To renew or not to renew? African nations reconsider EU fishing deals
- The European Union currently has fisheries access deals with 11 African countries, several of which are up for renegotiation this year.
- Under the deals, called Sustainable Fisheries Partnership Agreements (SFPAs), European fishing companies gain access to resource-filled foreign waters, while the African countries get cash.
- Senegal was the first country to sign such a deal, in 1979, but President Bassirou Diomaye Faye was elected in March after proposing to suspend it altogether in response to concerns that it’s unfair to local fishers. It’s not yet clear whether he will follow through, but his rhetoric reflects shifting arrangements in African fisheries, where the EU no longer dominates as it once did.
- Experts see this as a possible win for local control of precious marine resources, but they also caution that many of the alternative arrangements African governments are turning to instead of SFPAs are more socially and environmentally problematic, and less transparent.

Twilight zone fishing: Can we fish the ocean’s mesopelagic layer?
- Fishing experts are looking for ways to fish in the mesopelagic zone, a layer of water that stretches from 200-1,000 meters (660-3,300 feet) beneath the surface, which has, thus far, remained relatively unexploited.
- Many challenges stand in the way of making mesopelagic fishing a reality, such as the difficulties of finding and capturing mesopelagic fish, and processing them into usable products.
- Yet experts are working to overcome these obstacles, with one suggesting that mesopelagic fishing could begin in the next few years.
- Conservation experts have expressed concern about the possible start of mesopelagic fishing, arguing that it could cause environmental problems.

As plastic talks wrap up in Canada, fishers in Indonesia count the costs
- Fishers in the Thousand Islands archipelago off the Jakarta coast have reported extensive economic losses due to the scale of plastic waste littering their seas.
- Declining catch volume and costly repairs to boat engines are cited as drags on productivity, with one fisher telling Mongabay that his family now earns less than a decade earlier.
- Negotiators convened by the U.N. hope to conclude an international agreement in November that would limit the hundreds of millions of tons of plastic produced around the world each year.

Indonesia resumes lobster larvae exports despite sustainability, trade concerns
- The Indonesian government will resume a controversial policy of exporting lobster larvae, initially just to Vietnam, in exchange for investment in its own lobster-farming industry.
- The ban has met with controversy since it was introduced in 2016; a subsequent attempt to lift it failed after the fisheries minister at the time was arrested for taking bribes to issue export permits.
- The current minister says the lifting this time around is based on pragmatic considerations, with law enforcement efforts failing to stop the smuggling of lobster larvae.
- Critics say the move will benefit Vietnam more than it will Indonesia, given that the former’s far more advanced lobster-farming industry generates far more value from the sale of mature lobsters than Indonesia ever could from the sale of larvae.

Fewer fish and more rules lead to illegal catches, Italian fishers say
- The line between legal and illegal fishing in the waters off Italy’s Calabria region is often blurred, with fishers blaming stringent top-down regulations for constricting their traditional practices.
- The issue is further muddied by the presence here of the ‘ndrangheta or Calabrian mafia, which investigations have shown is involved in the fish trade and also uses it as cover for illicit activities such as drug smuggling.
- The Mediterranean Sea is experiencing a decline in fish stocks, ranging from 60-90% depending on the species, with the NGO Sea Shepherd Italia blaming illegal fishing for environmental damage.

No protection from bottom trawling for seamount chain in northern Pacific
- A recent meeting of the intergovernmental body that manages fisheries in the North Pacific Ocean failed to confer new protections for the Emperor Seamount Chain, a massive and richly biodiverse set of underwater mountains south of the Aleutian Islands.
- Bottom trawlers plied the Emperors aggressively in the past, decimating deep-sea coral communities and fish stocks.
- A proposal by the U.S. and Canadian delegations at the meeting of the North Pacific Fisheries Commission (NPFC) would have temporarily paused the limited trawling that continues there today, but failed to reach a vote.
- The NPFC did pass a separate proposal to regulate fishing of the Pacific saury (Cololabis saira), a severely depleted silvery fish that Japanese people traditionally eat in the fall.

Annual ocean conference raises $11.3b in pledges for marine conservation
- The 9th Our Ocean Conference (OOC) took place in Athens from April 15-17.
- Government, NGO and philanthropic delegates made 469 new commitments worth more than $11.3 billion to help protect the oceans, which was lower than in previous years.
- While some conference hosts and attendees celebrated the many successes of the OOC, there was also a shared concern that decision-makers aren’t moving fast enough to secure a sustainable future for the global ocean.

Caribbean startups are turning excess seaweed into an agroecology solution
- Sargassum, a type of brown macroalgae, has been inundating beaches across the Caribbean since 2011. It comes from the Sargasso Sea in the Atlantic Ocean.
- The seaweed has harmed Caribbean economies and human health, making it a national emergency in some island-nations.
- Over the past decade, entrepreneurs and scientists have found ways to turn sargassum into nutrient-rich biofertilizers, biostimulants and other organic products to boost agricultural yields while cutting back on chemicals.
- But there are hurdles to scaling the industry, including sargassum’s inconsistent arrival, heavy metal content and fast decomposition rates.

Global coral bleaching now underway looks set to be largest on record
- Scientists say that coral reefs are currently undergoing a global bleaching event, with more than 54% of the world’s coral reef areas in the territorial waters of over 50 countries experiencing heat stress. According to one scientist, the percentage of areas dealing with bleaching-level heat stress “has been increasing by roughly 1% per week.”
- To assess the current bleaching event, scientists drew on satellite-derived sea surface temperature data and in-water measurements.
- Experts say the current El Niño, a phase in the El Niño–Southern Oscillation (ENSO) climate pattern, in combination with rising global sea temperatures, is responsible for the extensive coral bleaching.
- Mongabay interviewed scientists most familiar with coral reef bleaching data, and experts attending the 9th Our Ocean Conference in Athens, taking place from April 15-17.

In Java Sea, vigilantism and poverty rise as purse seine fishing continues
- Fishing communities on small islands in the Java Sea and farther afield have long complained that large purse seine vessels are encroaching on traditional fishing grounds.
- On Sembilan Island, between the islands of Java and Borneo, local fishers have resorted to vigilantism due to what they say is inaction by authorities to prevent fishing with the purse seine, known locally as cantrang.
- The head of the local fisheries department told Mongabay Indonesia that fishers would see a crackdown against the boats.

Rewilding program ships eggs around the world to restore Raja Ampat zebra sharks
- A rewilding project aimed at saving endangered zebra sharks (Stegostoma tigrinum is sending eggs from aquarium sharks more than 12,000 kilometers (7,500 miles) away to nurseries in Raja Ampat.
- After hatching, the young sharks are kept in tanks until they are strong enough to release into the wild.
- Researchers hope to release 500 zebra sharks into the wild within 10 years in an effort to support a large, genetically diverse breeding population.
- A survey estimated the zebra shark had a population of 20 spread throughout the Raja Ampat archipelago, making the animal functionally extinct in the region.

Putting a value on Indonesia’s marine resources: Interview with Annisya Rosdiana & Heidi Retnoningtyas
- A group of experts led by Annisya Rosdiana from the Fisheries Resource Center of Indonesia (FRCI) is designing Indonesia’s ocean account to determine the exact abundance of the country’s maritime and fisheries resources.
- This initiative, begun in 2021, is part of the Ministry of Marine Affairs and Fisheries’ efforts to improve sustainable marine management.
- Indonesia’s ocean account is also part of the Global Ocean Accounts Partnership (GOAP), which aims to establish globally accepted ocean accounting methods.
- The initiative faces challenges due to data deficiencies, lack of coordination among government agencies, and weak enforcement of fisheries policies on the ground.

As a megaport rises in Cameroon, a delicate coastal ecosystem ebbs
- The deepwater port at Kribi, Cameroon, is a massive project, begun in 2011 and slated for completion in 2040.
- It aims to decongest the existing port at Douala and become a trade hub for all Central African countries.
- The port is located just a few kilometers from Cameroon’s only marine protected area, home to green, olive ridley and hawksbill turtles.
- While aiming to improve the country’s economy, the port has generated unintended environmental consequences, intensifying coastal erosion, increasing human pressure and pollution, and endangering marine life and local fishers’ livelihoods.

Indonesian court jails environmentalist for flagging illegal farms in marine park
- An Indonesian court has sentenced an environmental activist to seven months in jail for a Facebook post in which he criticized the growing problem of illegal shrimp farms operating inside a marine park.
- The court found that Daniel Frits Maurits Tangkilisan had “created unrest” because of his post, under a controversial 2008 law on online speech that’s been widely used to silence environmental and human rights activists.
- Three other activists face similar charges in the case, which centers on their efforts to highlight the presence of illegal shrimp farms inside Karimunjawa National Park, which is supposed to be a protected area.
- Fellow rights activists have lambasted the ruling against Daniel, saying it sets a dangerous precedent for exploitation of the justice system to silence and criminalize individuals.

Deep-sea mining’s future still murky as negotiations end on mixed note
- Between March 18 and 29, members of the International Seabed Authority (ISA), the U.N.-affiliated regulator of deep-sea mining activities in international waters, met for talks in Kingston, Jamaica.
- One focus of discussion was the ongoing revision of the regulations governing exploitation, which are still in draft form, but which member states are aiming to finalize by July 2025. Seabed mining activities could begin before then, as early as next year.
- ISA officials said “good progress” was made on the regulations. However, one NGO observer pointed out that there were “many areas where these negotiations have not progressed.”
- Delegates to the meetings also didn’t adopt either of two proposals to limit the ability of Greenpeace International to protest deep-sea mining activities at sea.

Indonesian activists face jail over FB posts flagging damage to marine park
- Four environmental activists in Indonesia face up to 10 months in jail for “hate speech” after complaining online about the proliferation of illegal shrimp farms inside a marine park.
- Karimunjawa National Park, which is supposed to be a protected area, has seen the number of such farms inside its borders proliferate in recent years, which groups like Greenpeace have linked to ecosystem degradation.
- Daniel Frits Maurits Tangkilisan is the first of the four members of the #SaveKarimunjawa movement to go to court; a verdict in his case is expected on April 4.
- All four men have been charged under a controversial 2008 law on online speech, which critics say has been abused vigorously by the Indonesian state to stifle dissent and opposition.

In Raja Ampat, pearl farming balances business and ecological sustainability
- In the Raja Ampat islands of eastern Indonesia, pearl farming thrives within a healthy marine ecosystem, with companies like PT Arta Samudra focusing on sustainable practices.
- Pearl farms are very secretive about their methods, which include the delicate process of implanting beads into oysters to cultivate pearls, a technique developed to accelerate pearl production.
- Challenges such as climate change impacts and maintaining a pristine environment highlight the importance of balancing industry growth with ecosystem preservation.
- With concerted efforts to protect marine habitats, Raja Ampat’s pearl industry aims for global recognition while emphasizing sustainability.

Communities worry anew as PNG revives seabed mining plans
- Coastal communities in Papua New Guinea’s New Ireland province rely on the sea for their livelihoods and culture.
- But Solwara 1, a resurgent deep-sea mining project aimed at sourcing metals from the ocean floor, could threaten their way of life, community leaders and activists say.
- They also say they haven’t been properly consulted about the potential pros and cons of Solwara 1, and government and company leaders have provided little information to the public about their plans.
- A coalition of leaders, activists and faith-based organizations called the Alliance of Solwara Warriors is opposing the project in Papua New Guinea and abroad, and calling for a permanent ban on seabed mining in the country’s waters.

Huge new no-fishing zones give Antarctic marine predators and their prey a break
- The government of the South Georgia and South Sandwich Islands (SGSSI), which operates as a British overseas territory, recently announced that it had established new no-fishing zones over 166,000 km² (64,100 mi²) of its existing marine protected area, and prohibited krill fishing in an additional 17,000 km² (6,600 mi²) of the MPA.
- These new no-fishing zones were established to protect krill-dependent marine wildlife, including baleen whales and penguins, while also considering the fisheries operating in the area, which target krill and other species.
- While conservationists initially pushed for further protections, they ultimately accepted the decision, with one calling it a “positive and good outcome.”
- However, Argentina, which claims the South Georgia and South Sandwich Islands as part of its Tierra del Fuego province, has expressed its dissatisfaction with the SGSSI government’s decision.

Madagascar takes key step toward improving transparency of its fisheries
- Madagascar recently released its first fisheries transparency report, part of an effort to open up, democratize, and improve the sustainability of its fisheries sector.
- The report is a key step in a process defined by the Fisheries Transparency Initiative (FiTI), a Seychelles-based nonprofit.
- It contains important information on traditional, artisanal and industrial fisheries, a list of the laws and regulations governing the sector, tenure arrangements, and access agreements — including previously undisclosed information.
- It also assesses the country’s transparency according to the availability and accessibility of data from six thematic areas as outlined by the FiTI Standard.

Indonesia unveils plan to launch a satellite network for maritime monitoring
- Indonesia plans to launch a satellite constellation starting in July to monitor its marine and fisheries resources more effectively.
- This constellation of 20 nanosatellites aims to actively manage conservation efforts and ensure economic benefits from marine resources.
- The satellites will feature radio frequency, imaging and vessel-tracking equipment, allowing officials “to know every condition in Indonesia from one [data] center.”
- Challenges such as budget cuts and low compliance among fishing companies underscore the need for technological solutions to protect Indonesia’s vast marine areas.

Report: Rising slaughter of small whales and dolphins threatens ocean balance
- Killings of small whales, porpoises and dolphins are rising, with more than 100,000 of these marine mammals slaughtered each year, according to a new report from German and British NGOs.
- Many regions report increased catches driven by demand for dolphin meat as food and shark bait in areas impacted by economic crisis and dwindling fish stocks.
- Failure to address unsustainable exploitation of small cetaceans exacerbates ecological imbalance and heavy metal toxicity risks to humans who eat them, according to the report.
- Insufficient legislation and enforcement remain critical issues, according to the report, which calls for international collaboration and stronger protection measures.

Fears of marine disaster loom after fertilizer-laden ship sinks in Red Sea
- The MV Rubymar, a cargo ship carrying about 21,000 metric tons of ammonium phosphate sulfate fertilizer, has sunk in the Red Sea following an attack by Yemen’s Houthi rebels, raising fears of an environmental disaster.
- In addition to the fertilizer potentially entering the ocean, the vessel is also leaking heavy fuel, which experts say will impact the marine environment.
- The Red Sea is known to harbor some of the world’s most heat-resistant coral reefs, which makes the sinking of the Rubymar particularly concerning.

‘Corals dying’ as yet more bleaching hits heat-stressed Great Barrier Reef
- Both aerial and in-water surveys have shown that the southern section of the Great Barrier Reef is undergoing extensive coral bleaching.
- Surveys have also shown “limited bleaching” in the northern part of the Great Barrier Reef.
- However, scientists and reef managers plan to conduct more air and in-water surveys to further assess the coral bleaching across all parts of the Great Barrier Reef.
- Scientists suspect but have not yet confirmed that a seventh mass bleaching event since 1998 is currently underway; the last mass bleaching event on the Great Barrier Reef happened in 2022.

PNG communities resist seabed mining: Interview with activist Jonathan Mesulam
- The government of Papua New Guinea appears poised to approve Solwara 1, a long-in-development deep-sea mining project in the country’s waters.
- However, PNG has signed onto several seabed mining moratoria, and scientists have urged caution until more research can determine what the effects of this practice will be.
- Proponents say the seafloor holds a wealth of minerals needed for batteries, especially for electric vehicles, and thus are vital for the transition away from fossil fuels.
- But coastal communities in PNG’s New Ireland province have mounted a fierce resistance to Solwara 1, arguing that it could damage or destroy the ecosystems that provide them with food and are the foundation of their cultures.

Norwegian salmon farms gobble up fish that could feed millions in Africa: Report
- Norwegian salmon farms are taking huge amounts of wild fish from West Africa, mining the food security of the region, according to a report from the U.K.-based NGO Feedback.
- In 2020, the industry produced salmon feed ingredients using up to 144,000 metric tons of small pelagic fish caught along the coasts of West Africa, where they could have fed between 2.5 million and 4 million people, according to the report.
- The analysis comes as the industry faces a wave of public opposition after revelations of high mortality rates and the sale of fish deemed unfit for human consumption, along with accusations of antitrust violations by the European Commission.

Hong Kong as a reef fish haven? These scientists want to get the word out
- For the past 10 years, marine biologist and conservationist Stan Shea has been leading a citizen-science program called the 114°E Hong Kong Reef Fish Survey to compile data on local reef fish species and raise awareness about the marine environment.
- The program relies on a core network of around 50 volunteer divers, who assist Shea with his mission to raise awareness about Hong Kong’s aquatic life.
- There are likely about 500 reef fish species in Hong Kong, but only about 460 have been identified so far; Shea and his team aim to find and document as many of the other overlooked as possible.
- Shea is also working on a photographic book about Hong Kong’s reef fish, which will be published in 2026.

With drop in illegal fishing comes rise in piracy, study in Indonesia finds
- Indonesia’s crackdown on illegal fishing is driving an increase in maritime piracy, a new study shows.
- In recent years, the government has taken harsh measures against illegal fishers, including banning foreign fishing vessels from its waters, and blowing up those it seizes.
- However, researchers say the crackdown’s success, without addressing the drivers of illegal fishing, including poverty, “can inadvertently shift effort from fishing to piracy.”
- Illegal fishing costs an estimated $3 billion in lost revenue for Indonesia, the world’s second-biggest producer of wild-caught seafood.

On Kaho’olawe, new technology could restore a sacred Hawaiian island
- The small Hawaiian island of Kaho‘olawe is a sacred site for Indigenous Hawaiians, who used it for navigational training, religious ceremonies, and fishing.
- But the island has faced decades of ecological destruction due to invasive plants and animals, erosion, and bombings as a test site by the U.S. military.
- A new conservation project has successfully tested a novel method using AI-equipped camera traps and an aerial drone to collect images of invasive cats, which have destroyed the island’s seabird populations, in dangerous and difficult-to-access parts of the island.
- But funding for the work on Kaho‘olawe remains scarce, and the drone project is now on hold as local organizations seek further funding to deal with the feral cats.

Find the manatee: New AI model spots sea cows from images
- A new computer model developed by engineers at the Florida Atlantic University uses deep learning to count manatees in images captured by cameras.
- The model has been trained to identify manatees in shallow waters, and can be used to identify where they aggregate, which can, in turn, be helpful to plan conservation actions and design rules for boaters and divers.
- However, the model can’t yet distinguish between adults and calves, or between males and females, both of which are details that are vital for conservation and research purposes.
- The engineering team says it plans to continue training the model in the months ahead, while also working with biologists to get their feedback on how to improve it further.

No sea change on marine policy from candidates as Indonesia heads to polls
- None of the three candidates running in Indonesia’s Feb. 14 presidential election have presented meaningful policy changes for the country’s coastal communities and marine resources, observers say.
- Indonesians are voting in the biggest single-day election in the world, but the failure by candidates to prioritize maritime issues is a major omission for the world’s biggest archipelagic country.
- Observers say the interests of fishing communities continue to be subordinated to those of industry and developers when it comes to competition for space and resources, and that none of this looks set to change under any of the three candidates.
- They also note that issues such as poverty in coastal areas, threats to marine ecosystems, and the marginalization of coastal communities persist despite the significant role these communities play in Indonesia’s fisheries sector.

Annual South Pacific fisheries meeting nets bottom trawling controversy
- The annual conference of the South Pacific Regional Fisheries Management Organisation (SPRFMO), an intergovernmental body, took place in Manta, Ecuador, between Jan. 29 and Feb. 2.
- SPRFMO, which manages fisheries across the vast international waters of the South Pacific Ocean, made key decisions on bottom trawling, labor rights, observation of squid-fishing vessels and transshipment at sea, a practice that can obscure the origin of illegally caught seafood.
- In what was perhaps the most controversial outcome of the meeting, delegates failed to adopt a proposal to complete the implementation of rules passed last year that would have limited bottom trawling of vulnerable marine ecosystems, such as coral communities.

EU parliament expresses disapproval of Norway’s deep-sea mining plans
- On Feb. 7, members of the European Parliament voted in favor of a resolution that raises concerns about Norway’s intentions to begin deep-sea mining activities.
- Although the resolution doesn’t hold any legal power, experts say it sends a strong signal to Norway that it doesn’t have the European support it may be relying on.
- Norway’s foreign ministry said that it has taken note of the resolution, adding that, like its European partners, it is committed to “sustainable ocean management.”
- In January, Norway voted to allow deep-sea mining exploration to commence in its waters.

Study: Indonesia’s new capital city threatens stable proboscis monkey population
- A recent study warns that the ongoing construction of Indonesia’s new capital city on the island of Borneo could destabilize the population of endangered proboscis monkeys currently thriving in the area.
- President Joko Widodo has characterized the development as green and with a minimal environmental impact, but concerns have arisen over the potential threat to the nearby Balikpapan Bay mangrove ecosystem that’s home to proboscis monkeys and other threatened wildlife.
- Scientists have advocated for sustainable development practices and emphasized the importance of respecting local biodiversity while constructing the new city, Nusantara.
- Their recommendations include legal protection for affected areas, habitat restoration, and collaboration with local stakeholders to mitigate the environmental impact.

In East Java, social media push against Indonesia shark & ray trade lacks bite
- Over a period of four months in late 2023, Mongabay spoke with fishers and traders dealing primarily in rays and sharks in Indonesia’s East Java province.
- Advertisements for shark and ray products continued to feature on social media platforms despite pledges by companies to prevent users from conducting transactions in wildlife.
- Indonesia’s fisheries ministry said more needs to be done to enhance traceability to crack down on trade in protected shark and ray species.

Cambodia sea turtle nests spark hope amid coastal development & species decline
- Conservationists in Cambodia have found nine sea turtle nests on a remote island off the country’s southwest coast, sparking hopes for the critically endangered hawksbill turtle (Eretmochelys imbricata) and endangered green turtle (Chelonia mydas).
- It’s the first time sea turtle nests have been spotted in the country in a decade of species decline.
- Two nests have been excavated to assess hatching success; conservationists estimate the nests could hold as many as 1,000 eggs.
- Globally, sea turtle populations are declining, largely due to hunting for food and the animals’ shells, used in jewelry; other threats to sea turtles include tourism development, pollution and climate change.

Critics push for more transparency at RFMOs that govern high seas fishing
- Around 17 regional fisheries management organizations (RFMOs) manage fishing in international waters, or the “high seas.”
- Scientists and civil society members have long criticized these international bodies for failing the high seas; many of the stocks they manage are overfished, research shows.
- Critics cite opaque decision-making as a key reason for conservation failures, and they’re making an increasingly vociferous case for RFMOs to become more transparent, citing their oversight of shared public resources.
- RFMO representatives, while citing internal rules as well as a need for privacy to maintain open negotiations among parties, point to recent steps toward transparency.

Mangrove crab sustainability is vital for fishers in Indonesia’s Aru Islands
- Mud crab fishing in Lorang village, Aru Islands, has been a vital livelihood since 2014, but a recent survey suggests signs of depletion, raising concerns among local fishers.
- The boom in crab fisheries began after a government moratorium on various commodities.
- Despite high economic value, a rapid assessment by Indonesian researchers reveals a decline in mud crab abundance, possibly due to overfishing exceeding natural regeneration.
- To address this, there’s a call for conservation efforts, including a wildlife protection reserve and agreements with neighboring villages to establish a “crab bank” for sustainable crab populations.

Overfishing leads to decline in Bangladesh marine fish stocks & diversity
- Bangladesh is facing a decline in marine fish stocks and diversity due to lack of knowledge among fishers, proper implementation of the Marine Fisheries Act and rampant use of industrial trawlers and unauthorized fishing gear in permitted fishing zones.
- The country has a 710-kilometer (440-mile) coastline with 121,110 square kilometers (46,760 square miles) of exclusive economic zones (EEZs) within the Bay of Bengal and is a hub of 740 aquatic species.
- The marine fisheries sector contributes about 15% of Bangladesh’s total fish production, which helps meet the population’s demands for animal protein.

Indonesia invites Turkish investors to develop tuna farms in Papua
- Indonesia has invited Turkish investors to participate in offshore tuna farming in the Papua region’s Biak Numfor district, aiming to make it a hub for tuna exports.
- The Indonesian fisheries ministry said Turkish fisheries operators can bring innovation to enhance productivity and ensure sustainability of the tuna fishery.
- Indonesia, a significant contributor to global tuna production, faces sustainability challenges due to excessive harvesting of wild tuna.
- The outreach to Türkiye is the latest in efforts to get foreign investors to help develop Indonesia’s various fisheries, including a similar offer earlier in January for Vietnam to invest in lobster farms.

First ever U.S. Indigenous Marine Stewardship Area declared in California
- The Tolowa Dee-ni’ Nation, Resighini Rancheria, and Cher-Ae Heights Indian Community designated the first ever Indigenous Marine Stewardship Area (IMSA) in the U.S. along the northern California coast.
- The tribes plan to steward nearly 700 mi2 (1,800 km2) of their ancestral ocean and coastal territories from the California-Oregon border to Little River near the town of Trinidad, California.
- As sovereign nations, the tribes say they’re not seeking state or federal agencies’ permission to assert tribally led stewardship rights and responsibilities; rather, they want to establish cooperative relationships recognizing their inherent Indigenous governance authority.
- The tribes aim to restore traditional ecological knowledge and management practices that sustained the area’s natural abundance before colonial disruption.

Report: Human tragedy stalks the prized Honduran lobster industry
- The Caribbean spiny lobster (Panulirus argus) is a coveted delicacy, with Honduras exporting $46.7 million worth of the shellfish in 2019, mainly to the U.S.
- But its flourishing trade comes at the expense of the Indigenous Miskito community living along Honduras’s Atlantic coast, according to an investigation published in December by nonprofit news outlet Civil Eats.
- Hundreds of Miskito lobster divers have died, and thousands more are injured or have become paralyzed in pursuit of the lobsters, the report noted.
- So far, efforts at reforming the Honduran lobster fishery have failed to adequately address the divers’ situation, according to the investigation.

Global shark deaths increasing despite finning bans, study shows
- A new study finds that shark mortality increased by 4% in coastal fisheries and decreased by 7% in pelagic fisheries, between 2012 and 2019, despite legislation to ban shark finning increasing tenfold over this period.
- Based on these findings, experts say shark finning regulations may not be effective in decreasing shark mortality, and may even create new markets for shark meat.
- However, the study also shows that successful management of shark fisheries can lead to a decrease in mortality; such is the case with retention bans and other measures taken by regional fisheries management organizations.

2023’s top ocean news stories (commentary)
- Marine scientists from six international research and conservation institutions share their list of the top ocean news stories from 2023.
- Hopeful developments this past year include a monumental global treaty to protect biodiversity on the high seas and the regulation of international trade in 97 species of sharks and rays under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
- At the same time, 2023 was the hottest year on record, with widespread bleaching of corals in the Caribbean and Great Barrier Reef, and many more hot years forecast as humanity’s emissions of greenhouse gases that cause global warming continue.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

Indonesia offers lobster larvae exports to Vietnam in exchange for investment
- Indonesia is seeking investment from Vietnam to develop Indonesia’s fisheries sector, especially the lobster farming industry, the country’s fisheries minister said during a visit to Hanoi.
- In exchange, Indonesia could supply up to 300 million lobster larvae to Vietnam and would stop seizing Vietnamese fishing boats encroaching into Indonesian waters, instead just turning them back.
- Jakarta banned exports of lobster larvae in 2016 to prevent the overharvesting of wild population from the country’s rich waters, but smuggling remains rampant.
- Despite concerns about potential harm to the domestic aquaculture industry, the government plans to finalize a decree to resume exports, citing the economic benefits and potential to reduce smuggling.

Spain sanctions fishing vessels for illegally ‘going dark’ near Argentine waters
- The Spanish government sanctioned 25 of its vessels for illegally turning off their satellite tracking devices while fishing off the coast of Argentina between 2018 and 2021.
- Experts say ships that “go dark” by turning off their trackers often do so to partake in illicit behavior, such as crossing into a nation’s exclusive economic zone (EEZ) without authorization.
- While some have praised the Spanish government’s actions, one expert says he doesn’t believe the sanctions go far enough.
- Most fishing activity in this region is also unregulated and unmonitored, which raises environmental concerns.

Salmon and other migratory fish play crucial role in delivering nutrients
- Pacific salmon can play a key role in transporting nutrients from marine to freshwater and terrestrial ecosystems.
- In the past, Pacific salmon and other anadromous fish that spawn in freshwater and spend part of their life in the ocean likely played a much larger role in global nutrient cycles, scientists find.
- But today, many populations of Pacific salmon and other anadromous fish are under pressure from habitat loss, overfishing, climate change, dams and other pressures that have greatly reduced their numbers, weight and ability to migrate freely.
- Population declines could further curtail their role in global nutrient transport in future, with increasing consequences, especially for nutrient-poor ecosystems that have relied in the past on migratory fish for significant nutrient additions.

Finance and support are key to fishers adopting eco-friendly gear, study shows
- Access to financing, the support of a peer group, and a general awareness of environmental problems are all factors that make it more likely a fisher will switch to using eco-friendly gear, a new study shows.
- The findings come from a three-month survey of nearly 650 blue swimming crab fishers on the north coast of the Indonesian island of Java.
- It found that those who made the switch also enjoyed significantly higher production and profitability, while also reducing their catch of egg-bearing female crabs, thus helping the sustainability of stocks.
- The study authors say these factors should provide valuable insights for fisheries policymakers in Indonesia and other less-industrialized countries.

Sumatran dugong hunter struggles to adapt to changing times
- The herbivorous dugong was classed as a vulnerable species in 1982 by the International Union for Conservation of Nature.
- Hunters like Munsa in Bintan, a cluster of islands between Sumatra and Singapore, have retired from hunting the mammal in response to conservation initiatives.
- However, Munsa complains that the family’s income has plummeted, and that he needs government to provide alternative livelihoods.

Still on the menu: Shark fin trade in U.S. persists despite ban
- An Al Jazeera investigative report has revealed that the trade in shark fins is still happening in the U.S. despite legislation banning the activity.
- The report also showed illegal shark finning operations occurring in Peru, currently the world’s largest exporter of fins due to laws that make this export legal, and in Ecuador, where sharks are landed in high volumes.
- A year ago, the international convention on wildlife trafficking enacted shark trade bans, but this has not yet stamped out the global fin trade, prompting experts to call for better enforcement and scrutiny.

Farewell, Java stingaree: Scientist declare the first marine fish extinction
- In December 2023, scientists declared the Java stingaree (Urolophus javanicus), a species of stingray, extinct.
- It’s the first marine fish confirmed to have gone extinct due to human actions.
- Scientists know very little about the species, which they haven’t spotted since a naturalist purchased the specimen from which he described the species at a fish market in Jakarta in 1862.

U.S. auctions off endangered whale habitat for oil and gas drilling
- On Dec. 20, the U.S. Department of the Interior’s Bureau of Ocean Energy Management (BOEM) held a lease sale to auction off oil and gas drilling rights in the Gulf of Mexico.
- Environmental groups and the U.S. Interior Department had tried to postpone this sale due to concerns about protecting the critically endangered Rice’s whale, a species whose key habitat overlaps with the lease sale areas.
- Scientists estimate there are fewer than 50 Rice’s whales left, and that the primary threat to the species is the oil and gas industry.
- While the lease sale went through without any protections for the Rice’s whale, environmental groups continue to explore legal and political avenues to ensure the species’ survival.

‘Shark dust’ helps researchers ID threatened species in Indonesia fish trade
- Researchers have developed a new tool to identify a wide range of threatened and protected sharks being processed at fish factories in Indonesia.
- The method relies on DNA analysis of “shark dust,” the tiny fragments of skin and cartilage swept from the floors of fish-processing plants and export warehouses.
- From 28 shark dust samples collected from seven processing plants across Java Island, they found the genetic sequences of 61 shark and ray species.
- About 84% of these are CITES-listed species, meaning there are official restrictions in place on the international trade in these species.

Indonesia delays enforcement of widely panned fisheries policy
- The Indonesian government has pushed back the implementation of a new fisheries policy based on catch quotas amid near-universal criticism from stakeholders.
- The fisheries ministry said the year-long delay would allow more time to prepare the fundamental infrastructure, but some observers speculated it was likely also linked to political factors.
- The quota-based fisheries management policy, introduced in March this year, will have affected industrial, local and noncommercial fishers, while small fishers are exempted from the quota.
- The fisheries ministry, however, said it would use the extended time to increase efforts for public outreach, education and gaining support for the implementation of the new policy.

The ex-shark fishermen teaching schoolkids how to protect the environment
- Shark conservationist Kathy Xu joined with ex-shark fishermen on the Indonesian island of Lombok to launch The Dorsal Effect.
- The eco-enterprise teaches students about the marine environment through snorkeling trips, coral health checks and beach trash cleanups.
- The Dorsal Effect helps provide an alternative source of income for the former shark fishermen of Lombok and aims to stop the shark finning trade.

Vast new MPAs are PNG’s first to be co-managed by Indigenous communities
- On Nov. 12, the government of Papua New Guinea declared two large new marine protected areas totaling more than 16,000 square kilometers (6,200 square miles) that reportedly triple the country’s marine area under protection.
- The announcement capped a six-year effort led by U.S.-based NGO Wildlife Conservation Society to consult with local communities about how to set up the MPAs to curtail the harvest of threatened species and restore the health of fisheries that people have depended on for generations.
- The NGO called the announcement “one of the first and most ambitious community-led MPA wins” since countries agreed last year to protect 30% of land and sea area by 2030 under the U.N. Convention on Biological Diversity.
- However, some observers note the potential problems that could arise from foreign-led conservation in an area experiencing poverty, conflict, and minimal government support, and there is widespread agreement that the MPAs’ success will depend on securing financing for enforcement.

Did the tides turn for oceans at COP28? Climate summit draws mixed reviews
- The ocean featured in many negotiations around the climate crisis at the U.N. climate summit known as COP28, which took place in Dubai between Nov. 30 and Dec. 13.
- The final version of the global stocktake (GST), which served as the main agreement for COP28, referred to the importance of protecting and preserving the ocean and coastal ecosystems, and called for “ocean-based action.”
- However, experts say the GST does not capture the necessary urgency to curtail fossil fuel emissions and may encourage the launch of controversial and still-untested geoengineering techniques that aim to lock away carbon in the ocean.
- COP28 was also the stage for several large pledges to support the protection of marine and coastal ecosystems.

Philippines oil spill may reverberate long after cleanup declared complete
- On March 1, the MT Princess Empress oil tanker sank in the Philippines, carrying 900,000 liters (237,754 gallons) of industrial fuel oil. A huge oil slick polluted local waters and prompted authorities to impose a ban on fishing that sent local communities into a tailspin.
- The wreck occurred in the Verde Island Passage, between the Philippines’ main islands of Luzon and Mindoro, an area with the highest concentration of marine biodiversity in the world.
- The spill cleanup activities are now finished, and life is returning to normal in many places. However, experts say the effects of the oil spill on the ecosystem could linger over the long term.
- The spill has reinvigorated calls for the Philippine Legislature to pass a law declaring the entire Verde Island Passage a marine protected area.

With Indonesia’s new fishing policy starting soon, fishers still mostly unaware
- Indonesia is scheduled to enforce a new fisheries policy at the start of the new year, but new reports have highlighted persistent inadequacies in the strategy.
- The office of the Indonesian Ombudsman says the quota-based fisheries management policy in general lacks accountability and transparency, including broader consultation with fishing communities.
- A separate report from Destructive Fishing Watch (DFW) Indonesia, an NGO, similarly found that many fishers had very limited awareness of the regulation changes and that existing fisheries infrastructure was inadequate to support the new strategy.
- Both organizations have called on the fisheries ministry to boost its efforts in public outreach about the new policy and ensure infrastructural readiness at all levels of government in the short time remaining before the policy goes into force.

Last of the reef netters: An Indigenous, sustainable salmon fishery
- Reef net fishing is an ancient, sustainable salmon-harvesting technique created and perfected by the Lummi and other Coast Salish Indigenous people over a millennium.
- Rather than chasing the fish, this technique uses ropes to create an artificial reef that channels fish toward a net stretched between two anchored boats. Fishers observe the water and pull in the net at the right moment, intercepting salmon as they migrate from the Pacific Ocean to the Fraser River near present-day Washington state and British Columbia.
- Colonialism, government policies, habitat destruction, and declining salmon populations have separated tribes from this tradition. Today, only 12 reef net permits exist, with just one belonging to the Lummi Nation.
- Many tribal members hope to revive reef net fishing to restore their cultural identity and a sustainable salmon harvest but face difficulties balancing economic realities with preserving what the Lummi consider a sacred heritage.

Indonesia launches new front in climate campaign focusing on seagrass
- Indonesia has published a road map for seagrass protection and rehabilitation, as part of its efforts to mitigate the impacts of the climate crisis.
- Seagrass meadows are estimated to sequester carbon dioxide from the atmosphere at a much greater rate, hectare for hectare, than even tropical rainforests.
- Indonesia has long been recognized as a crucial country for protecting the underwater flowering plants, as it’s estimated to host at least a tenth of the world’s seagrass meadows.

Fish out of water: North American drought bakes salmon
- An unprecedented drought across much of British Columbia, Canada, and Washington and Oregon, U.S., during the summer and fall months of June through October could have dire impacts on Pacific salmon populations, biologists warn.
- Low water levels in streams and rivers combined with higher water temperatures can kill juvenile salmon and make it difficult for adults to swim upriver to their spawning grounds.
- Experts say relieving other pressures on Pacific salmon and restoring habitat are the best ways to build their resiliency to drought and other impacts of climate change.

Indonesia welcomes new Singapore regulation to help curb lobster smuggling
- A new reexport regulation in Singapore could help stem the smuggling of lobster larvae from neighboring Indonesia.
- The city-state is a key destination for the contraband and a transit point for lobster larvae reexported to third countries like Vietnam and China.
- Under the new regulation, reexporters in Singapore will have to get health certificates for live animals from the country of origin, which in theory should be impossible for smugglers.
- Indonesian authorities have cautiously welcomed the plan, but say both countries must work more closely on the long-running problem.

Lethal or not? Australia’s beaches are a crucible for shark control methods
- For decades, Australia’s east-coast states have attempted to keep beachgoers safe from sharks by deploying entangling shark nets and culling species deemed dangerous.
- Recent figures published by the state of New South Wales reveal that almost all the animals caught in the nets during the 2022/23 summer season were “nontarget” species, including turtles, dolphins and endangered shark species, the majority of which died due to entanglement in the nets.
- In contrast, the west-coast state of Western Australia has abandoned a shark culling regime in favor of nonlethal alternatives, such as drone monitoring and “eco barriers,” swimming enclosures that keep marine life out but do not risk entanglement.
- Despite calls from environmental groups to exclusively adopt nonlethal technologies, shark control programs are continuing in both New South Wales and its northern neighbor, Queensland, during the 2023/24 Australian summer.

Is ocean iron fertilization back from the dead as a CO₂ removal tool?
- After a hiatus of more than 10 years, a new round of research into ocean iron fertilization is set to begin, with scientists saying the controversial geoengineering approach has the potential to remove “gigatons per year” of carbon dioxide from Earth’s atmosphere.
- The idea behind ocean iron fertilization is that dumping iron into parts of the ocean where it’s scarce could spark massive blooms of phytoplankton, which, when they die, can sink to the bottom of the sea, carrying the CO₂ absorbed during photosynthesis to be sequestered in the seabed for decades to millennia.
- So far, proof that this could work as a climate-change solution has remained elusive, while questions abound over its potential ecological impacts.
- Scientists with the Woods Hole Oceanographic Institution in Massachusetts, U.S., recently received $2 million in funding from the U.S. government that will enable computer modeling research that could pave the way for eventual in-ocean testing, effectively reviving research into ocean iron fertilization.

Dominica set to open world’s first reserve centered around sperm whales
- The tiny island nation of Dominica has announced that it will create a 788-square-kilometer (304-square-mile) reserve to protect endangered sperm whales.
- Most of the sperm whales that live off the coast of Dominica are part of the Eastern Caribbean Clan, which currently has a population of fewer than 300 individuals.
- Sperm whales in this region are threatened by fishing gear entanglement, pollution, boat strikes, and even tourism.
- The new reserve aims to protect whales by restricting activities such as fishing, vessel traffic and tourism, while not entirely banning them.

‘Very good progress’ but nothing firm as deep-sea mining rules are hashed out
- Between Oct. 30 and Nov. 8, representatives of the 36 member states of the the International Seabed Authority (ISA) council met in Kingston, Jamaica, to work on a set of regulations that would govern how deep-sea mining activities could proceed.
- Previously, at the ISA meetings that took place in July 2023, delegates agreed to try to finalize the regulations by July 2025.
- However, observers say they believe the regulations are far from being complete, despite continued work on the text.
- The Metals Company (TMC), a Canadian firm that could be the first in the world to begin deep-sea mining, has indicated that it intends to submit an application for exploitation following the July 2024 meeting; if this application is approved, mining could start in the near future without regulations to govern this activity.

Climate change threatens the North Atlantic’s currents, ecosystems and stability (analysis)
- The Atlantic Meridional Overturning Circulation (AMOC) is a vital component of the Earth’s global ocean circulation, and encompasses a network of currents within the Atlantic Ocean.
- Current research shows a possible slowing or stopping of the AMOC due to climate change, with direct and major impacts on marine ecosystems, weather variability, and food security in North America and Europe, and by extension the rest of the world.
- “A significant and sustained weakening of the AMOC has the potential to lead to its outright collapse, which would have far-reaching and mostly irreversible effects on marine and terrestrial ecosystems,” a new analysis explains.
- This post is an analysis. The views expressed are those of the author, not necessarily of Mongabay.

Galápagos waters yield massive deepwater corals in latest biodiversity find
- Researchers have found two new deepwater coral reefs, including one that spans more than 800 meters, or half a mile long, in the waters around the Galápagos Islands.
- They were discovered through the process of mapping the seafloor in Galápagos Marine Reserve with laser scanning technology.
- The reefs displayed a diversity of stony coral species and other organisms such as crustaceans, sharks and skates.
- The discovery of these two reefs occurred six months after the first discovery of deepwater reefs in the waters of the Galápagos Islands.

Key Indonesian fish populations depleted & new assessments needed, study shows
- The wild populations that sustain a significant Indonesian fishery are more depleted than the government had estimated, as highlighted by a recent scientific study.
- The authors have called for a reevaluation of the method used to assess fish stocks to address the overexploitation of these populations.
- The Indonesian deep-slope demersal fisheries have helped position Indonesia to be the world’s second-largest exporter of snapper species.

O.K. Coral: Outlaw fisher turns reef marshal in Indonesia’s Sumbawa
- Former dynamite fisher Amiruddin has ceased using destructive fishing practices and become a marine conservationist in his native Sumbawa.
- In 2010, Amiruddin was arrested and almost died while using poison to kill fish off Sumbawa’s west coast.
- Today he has installed lattices to support coral growth in the islands where he fished with explosives and poison in his youth.

Amid record melting, countries fail again to protect Antarctic waters
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with protecting marine life and managing fisheries in the Southern Ocean, met from Oct. 16-27 in Hobart, Australia, with 26 member countries and the European Union participating.
- For the seventh year in a row, the CCAMLR declined to establish new marine protected areas (MPAs) around Antarctica, despite having committed to creating “a representative network of MPAs” in 2009.
- Scientists, conservationists and some governments have been pushing for greater protections, concerned that the melting ice in Antarctica has reached alarming levels, jeopardizing some key populations of penguins, krill, whales, seals and other marine animals.
- The stalemate came even as a new threat to wildlife emerged in the region: the discovery last week that a virulent form of avian flu had reached Antarctic bird colonies.

The Indo-West Pacific harbors two distinct mangrove hotspots, study says
- New research on slugs has found two types of mangrove forests in the Indo-West Pacific region, highlighting their much-needed protection against deforestation and rising sea levels.
- The Indo-West Pacific is known to have the highest diversity of mangrove plants in the world, but it wasn’t previously clear which parts of the region had peak diversity.
- The latest research found the mangrove forests of the archipelagic region that spans from Papua New Guinea to Malaysia differ in numerous characteristics, including sediment size, freshwater input and plant species.

New Caledonia expands strictly protected coverage of its swath of the Pacific
- New Caledonia, an overseas territory of France in the Pacific, recently announced that it would highly protect 10% of its economic exclusive zone (EEZ).
- These new highly protected areas will be off-limits to industrial activities such as fishing, drilling and mining.
- A decade ago, New Caledonia designated its entire EEZ as a marine protected area, the Natural Park of the Coral Sea, but industrial activities were permitted across 97.6% of that area at the time.

Can aquaculture solve the Mediterranean’s overfishing problem?
- In the Mediterranean, 73% of commercial fish stocks are fished beyond biologically sustainable limits.
- Part of the strategy to reduce overfishing promoted by the General Fisheries Commission for the Mediterranean, a regional fisheries management organization, is to promote the expansion of aquaculture, which is growing rapidly.
- However, most fish farms in the region produce carnivorous species, causing concern among experts and NGOs about the risk of worsening the burden on wild marine stocks to produce enough feed.

With record ocean temps, is the Great Barrier Reef facing catastrophe?
- The inaugural international edition of the famed South by Southwest (SXSW) film festival and conference took place from October 15-22, 2023 in Sydney and Mongabay spoke with some of the most interesting presenters there.
- On this edition of the Mongabay Newscast, multiple guests working in coral reef conservation, kelp reforestation and sustainable agriculture detail their projects and challenges they’re tackling.
- Like the catastrophic Great Barrier Reef bleaching event of 2016, if the current conditions line up just right, “we could lose a huge part of the reef by February,” says guest Dean Miller of the Forever Reef Project, which is now racing to add the final coral specimens to its “biobank.”
- Guests also include John “Charlie” Veron from the Forever Reef Project, Mic Black from Rainstick, and Adriana Vergés from the Kelp Forest Alliance.

Report: Half of MSC-certified ‘sustainable’ tuna caught with controversial gear
- Tuna fisheries often rely on fish aggregating devices (FADs), floating human-made structures that fish congregate around, which makes it relatively easy to catch them, but which have also raised concerns about high rates of bycatch, capture of juvenile tuna, and pollution.
- Despite these concerns, the number of tuna fisheries using FADs that are certified sustainable under the standards of the Marine Stewardship Council (MSC), the largest ecolabeling scheme for wild fisheries, has soared, and FAD-fished tuna now account for more than half of all MSC-certified tuna, according to a new report from France-based nonprofit BLOOM Association.
- The report contends this constitutes a weakening of MSC standards in order to meet market demands for tuna.
- The MSC has refuted this claim, pointing to steps that certified fisheries are taking to reduce and study the impact of FADs.

As population ‘flattens,’ North Atlantic right whales remain at risk
- A new population estimate for North Atlantic right whales found about 356 individuals left in 2022, which suggests the population trend is “flattening.”
- In 2021, scientists previously estimated there were 340 right whales, although this number was later revised to 364 to account for several newborn calves.
- Despite there not being a notable difference between the population estimates in 2021 and 2022, scientists say North Atlantic right whales are still in danger of going extinct and that urgent measures need to be put into place to protect them.

Indonesia renews effort to resume controversial lobster larvae exports
- The Indonesian government is drafting a new policy that could allow the resumption of lobster larvae exports, which were banned in 2016 to prevent overharvesting of wild stocks.
- The fisheries ministry says a resumption is necessary to boost local fishers’ earnings and develop the domestic aquaculture industry.
- However, critics say the new policy mirrors a previous attempt to resume exports in 2020, which spawned a corruption scandal that led to the fisheries minister at the time being jailed.
- The ministry says this time around the policy will be monitored and enforced more strictly, although questions still remain over how sustainably lobster larvae can be harvested from the wild.

Iceland’s whaling paradox (commentary)
- As Iceland’s latest whaling season comes to a close, a heated debate continues over the ethics and sustainability of the country’s policy on these marine mammals.
- Filmmaker and activist Micah Garen — who co-directed the documentary “The Last Whaling Station” — shares his thoughts on what may be the nation’s last whaling season.
- “The paradox of whaling is the inherent contradiction between a utilitarian and Kantian world view. If you believe your choices matter, then ending whaling now is the only ethical, moral and philosophical choice we can make,” he argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

An ‘aquatic moonshot’ in Vietnam aims to fight livestock methane with seaweed
- Scientists from the R&D company Greener Grazing aim to reduce global greenhouse gas emissions by growing and marketing a red seaweed (Asparagopsis taxiformis) as an additive for livestock feed.
- Worldwide, some 3 billion cattle and sheep produce roughly 231 billion pounds of methane annually; researchers estimate some 100 million tons of A. taxiformis would be needed to eliminate 98% of those emissions, a figure that’s roughly three times current global production of all seaweeds.
- Greener Grazing is experimenting with growing A. taxiformis in central Vietnam’s Van Phong Bay, but there are challenges.
- Skeptics also say the benefits of seaweed are limited in both the amount of methane that can be reduced as well as the capacity for scaling production to meet the size of the problem.

Seaweed: The untapped economic potential for Bangladesh
- Bangladesh currently produces some 400 tons of seaweed, valued at 55 million taka (about $500,000), while a study suggested the country could produce 50 million tons of seaweed annually by 2050.
- Despite the potential to grow and earn more foreign currency through export, the sector is dealing with a number of difficulties, including inadequate investment as well as proper guidelines and regulations.
- According to the Food and Agriculture Organization (FAO), seaweed farming is one of the fastest-growing aquaculture sectors globally, with an annual production of about 33 billion tons, valued at $11.8 billion.

Microplastics pose risk to ocean plankton, climate, other key Earth systems
- Trillions of microplastic particles in the ocean threaten marine life, from huge filter-feeders to tiny plankton. Although not lethal in the short term, the long-term impacts of microplastics on plankton and marine microbes could disrupt key Earth systems such as ocean carbon storage and nitrogen cycling.
- Oceans represent Earth’s largest natural carbon store and are crucial to mitigate atmospheric CO2 increase. Carbon taken up by plankton and stored in the deep ocean — known as the biological carbon pump — is a major process in ocean carbon storage. Microplastics may “clog” this pump and slow ocean carbon uptake.
- Microplastics in marine sediments alter microbial communities and disrupt nitrogen cycling, potentially magnifying human-caused problems like toxic algal blooms. Changes in plankton communities at the ocean surface could exacerbate deoxygenation driven by climate change, starving marine organisms of oxygen.
- Small plastic particles are impossible to remove from the oceans with current technology, so stopping pollution is a priority. Plastic production continues to soar year-on-year, but a U.N. treaty to address plastic pollution could offer a glimmer of hope that the international community is ready to take action.

For Indonesia’s Kei islanders, a marine protected area makes perfect sense
- Fishing communities in Indonesia’s Kei Islands support the idea of a marine protected area to safeguard their main source of livelihood from unsustainable fishing and climate change impacts.
- That’s the finding of a new study by local researchers, who found that the majority of respondents said they were also willing to contribute a token annual payment for the upkeep of such an MPA.
- The researchers have proposed the MPA to the local government and council, and say they hope that if it’s accepted, it could serve as a template for other MPAs in the region.
- The waters around the Kei Islands are blessed with some of the richest fish stocks in Indonesia, but destructive fishing practices and the impacts of climate change are threatening the age-old fishing tradition here.

Seventy-plus nations sign historic high seas treaty, paving way for ratification
- As of Sept. 22, 76 nations and the European Union had signed the high seas treaty while gathered at the 78th U.N. General Assembly in New York.
- After signing the treaty, each nation must ratify it. Then, once 60 nations have ratified the treaty, it will come into force after 120 days.
- The high seas encompass two-thirds of the world’s oceans, but only 1% currently has protected status.

First Nation and scientists partner to revive climate-saving eelgrass
- Seagrass meadows, of which eelgrass is a key species, are some of the most biodiverse and productive ecosystems in the ocean, and play a crucial role in sequestering carbon.
- But eelgrass is disappearing rapidly around the globe, and in Canada, questions remain about where exactly these meadows are distributed, and how effective they are at storing carbon.
- A collaborative project between marine biologists and Indigenous Mi’kmaq communities is attempting to answer these questions in eastern Canada while also restoring lost eelgrass meadows.
- The project could help with eelgrass’s long-term survival in the area, as researchers identify eelgrass populations that are more resilient to climate change, and communities work toward eelgrass conservation.

Fisherwomen fight plan for coastal salt farms on Indonesia’s Madura Island
- A group of women in Sumenep district of East Java province is leading a protest against the local government’s proposal to develop a salt farm on 20 hectares (49 acres) of land on the coast of Gersik Putih village.
- In 2009, the local government issued land titles on 73 hectares (180 acres) of land along the coast of Tapakerbau hamlet in Gersik Putih, and all of it was to become salt farms.
- The fishers say the plan could jeopardize their fishing jobs and the sustainability of the marine ecosystem on which they have for generations depended for their livelihoods, and they say they believe the salt ponds have exacerbated the flooding there in recent years.
- The protest in Sumenep is one of many against plans for the development of coastal aquaculture in Indonesia, a country that has the world’s second-longest coastline.

‘Totally unsustainable’ sand mining harms marine environments, new data suggest
- New data from the newly launched platform Marine Sand Watch suggest that the dredging industry is extracting about 6 billion tons of sand from the marine environment annually.
- Experts say the extraction of sand can have numerous impacts on the marine environment, such as harming biodiversity, polluting water and making coastlines more vulnerable to sea level rise.
- While the sand mining industry is currently operating at unsustainable levels, experts say there are solutions to mitigate its damage.

For the oceans, global community must fund Sustainable Development Goal 14 (commentary)
- Oceans sustain life by providing myriad ecosystem services and foods which over three billion people depend on for survival, so its conservation is covered in Sustainable Development Goal (SDG) 14.
- Though #14 is underfunded, leaders of the global community can take action during the 2023 SDG Summit taking place today and tomorrow, 18-19 September, in New York City.
- “We call on the President of the General Assembly and donor governments to increase investments in the ocean [as it is] vital to the success of each of the other sustainable development goals. We must ensure a vital ocean for the billions that depend upon its health,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

In Indonesia, ‘opportunistic’ whale shark fishery shows gap in species protection
- Indonesia has since 2013 banned the capture, trade and exploitation of whale sharks, a protected species.
- Yet scores of records from 2002-2022 shown whale sharks continue to be butchered and sold along the southeastern coast of Java Island after either beaching or being unintentionally caught by fishers, according to a new study.
- The continuing illegal exploitation shows the need for more awareness raising against it by conservation authorities and groups, experts say.
- Indonesia is home to the longest coastline in Asia, and its waters serve as both a habitat and an important migratory route for species of marine megafauna like whale sharks.

Study finds old pear trees make for surprisingly rich reef habitats
- In a new study, researchers used old pear trees to create artificial reefs and settled them in the Wadden Sea in the Netherlands to see what kinds of marine biodiversity aggregated on or around them.
- They found that the tree reefs attracted a surprising amount of biodiversity over a short period of time, including sessile organisms like barnacles and mobile species like fish and crabs.
- The authors say tree reefs can be replicated in other parts of the world, mainly temperate regions.

Small-scale fishers in Indonesian isles flag use of banned net by outsiders
- Fishers on a group of small islands in the Java Sea are calling for a crackdown on larger boats using a banned type of seine net in their waters.
- The Masalembu Islands, which lie in one of the most heavily trafficked fishing zones in Indonesia, have frequently seen boats from elsewhere encroach into the near-shore zone that’s reserved for small-scale traditional fishers.
- The local fishers say these bigger boats typically use a cantrang net, banned by the fisheries ministry but still in widespread use amid a lack of law enforcement.
- The fishers have petitioned the government to clearly designate the traditional fishing zone that should be strictly off-limits to these cantrang boats.

Pacific alliance adopts moratorium on deep-sea mining, halting resurgent PNG project
- The Melanesian Spearhead Group put in place a moratorium on deep-sea mining within its member countries’ territorial water in a declaration signed Aug. 24.
- Leaders from Fiji, Papua New Guinea, the Solomon Islands, Vanuatu and an alliance of pro-independence political parties known as FLNKS from the French territory of New Caledonia said more research is needed to establish whether mining the seabed below 200 meters (660 feet) is possible without damaging ecosystems and fisheries.
- The moratorium ostensibly thwarts the return of Nautilus Minerals, a Canadian company, to Papua New Guinea and its Solwara 1 project in the Bismarck Sea, where it had hoped to mine gold and copper from sulfide deposits on the seafloor.
- Proponents of deep-sea mining say that minerals found deep beneath the ocean are necessary for the production of batteries used in electric vehicles and thus are critical in the global transition away from fossil fuels.

International outcry as Iceland lifts ban on what could be last whale hunt
- The Icelandic government has announced that commercial whaling will recommence following a two-month suspension of the activity, albeit with increased monitoring and stricter hunting regulations.
- The government temporarily banned whaling in June due to animal welfare concerns, but the ban expired on Aug. 31.
- The decision to restart whaling has drawn criticism from environmentalists and animal rights advocates.
- Only one company in Iceland currently has a whaling license, and it’s set to expire this year, with no guarantee the government will renew it for the coming years.

Indonesia, Singapore to work more closely against lobster larvae smugglers
- Indonesia has called for Singapore’s commitment to shut its borders to illegal exports of lobster larvae.
- Indonesia has since 2021 banned exports of wild-caught lobster larvae, but Singapore still permits their import, serving as both a key market and a regional trading hub.
- Lobsters are among Indonesia’s top fisheries commodities, but the illegal export of larvae and baby lobsters costs the country billions of rupiah in lost revenue and threatens the declining wild population of the shellfish.
- The fisheries ministry puts the latest estimate of potential wild lobster stock in Indonesian waters at 27 billion, but many of the officially sanctioned fishing zones are overfished, with the rest being harvested at maximum capacity.

Expected ship traffic to LNG Canada port could see whale deaths also rise
- The nutrient-rich ancestral waters of the Gitga’at First Nation in northern British Columbia are a critical habitat for fin, humpback and killer whales.
- The development of a $35.5 billion LNG terminal threatens these whales, as shipping traffic in the region is projected to surge, leading to more frequent encounters between whales and ships, a recent study warns.
- It uses whale movement data and predicted ship traffic modeling to conclude that two fin whales and 18 humpback whales could be killed each year in ship strikes in Gitga’at territorial waters.
- Researchers suggest mitigation measures like reducing ship speeds in whale hotspots and restricting ship traffic during August, when whales are most abundant in these waters.

Deep-sea mining project in PNG resurfaces despite community opposition
- An embattled deep-sea mining project appears to be moving ahead in Papua New Guinea, according to officials in the Pacific Island nation, despite more than a decade of opposition from local communities on the grounds that it could harm the fisheries on which they rely as well as the broader ecosystem.
- Backers of deep-sea mining say it could help provide the gold, copper and other minerals necessary for the transition to electric vehicles and away from fossil fuels.
- But deep-sea mining has not yet happened anywhere in the world, and scientists, human rights groups and Indigenous communities highlight the lack of evidence demonstrating its safety.
- The Alliance of Solwara Warriors is a group of Indigenous communities and church organizations that have been fighting the Solwara 1 project in Papua New Guinea, which received the world’s first deep-sea mining license from PNG in 2011.

Indonesian fishers not biting at new policy perceived as undermining them
- The Indonesian fisheries ministry issued a decree earlier this year introducing a quota-based fisheries management policy aimed at maximizing state revenue from the sector.
- A new study, however, has found that the new policy is unpopular with fishers, who say it reduces the role of local authorities and fishing communities.
- Local stakeholders’ responses also suggest the policy only benefits large-scale investors and commercial fishers, who are perceived to have a high negative impact on the environment.
- Indonesia’s fisheries sector plays a major role in the global seafood supply, with the country home to some of the world’s richest marine biodiversity.

As Bangladesh’s crab fishery booms, its wild stocks suffer the fallout
- Crab harvests in Bangladesh are booming to meet thriving export demand, but the rates at which wild stocks are being depleted may be unsustainable, experts warm.
- Researchers say the loss of large numbers of mud crabs from ecosystems like the Sundarbans mangroves could trigger an ecological imbalance.
- Bangladesh exported about $35 million worth of crabs in the 2019-2020 fiscal year, with the trend expected to increase to markets like the U.S., the EU and Singapore.
- Experts have called for more efforts to hatch crabs on aquafarms as a way to ease the pressure on wild stocks, but this option isn’t available yet at commercial scale.

Video: Rio de Janeiro’s defender of mangroves
- Guanabara Bay in Rio de Janeiro has suffered for decades from inefficient sewage treatment, oil spills and mangrove deforestation.
- For more than 30 years, biologist Mario Moscatelli has been fighting to reverse this process and revitalize the landscape.
- For denouncing corruption, environmental crimes and government inaction, he faced intimidation and even death threats.

Indonesian illegal shark and ray exports remain rampant amid poor monitoring
- Indonesia allows the trade of some endangered shark and ray species, but illegal exports remain rampant and unchecked.
- Mongabay-Indonesia conducted an investigation earlier this year to learn about the regulations, the loopholes and the challenges within the complex trade and fisheries of sharks and rays.
- The investigation found that the lack of oversight in the field was the leading cause of illegal shark and ray trade in the country.
- Indonesia is home to more than a quarter of the world’s 400 known shark species; a fifth of all shark species are endangered.

Madagascar signs new ‘sustainable’ tuna deal with the EU
- In late June, Madagascar and the European Union struck a new four-year deal allowing fishing vessels flagged to EU countries to resume harvesting tuna in Madagascar’s waters after an unusual four-and-a-half-year gap.
- The EU says the deal benefits Madagascar by providing key funding to support fisheries governance, and civil society groups praised the Madagascar government for creating a more inclusive and transparent negotiating process than in the past.
- However, critics contend that the deal offers little benefit to the citizens of Madagascar, one of the poorest countries in the world, and enables European vessels to exacerbate the overfishing of Indian Ocean tuna stocks.

Study: Protecting marine life is a big benefit to local communities, too
- A new study of the Mesoamerican Reef in the Caribbean found that marine protected areas (MPAs) are not only beneficial for conservation but can also lift up the socioeconomic status of the local and Indigenous communities that live near them.
- Led by the Smithsonian Environmental Research Center, the study used data from the Healthy Reef Initiative and USAID to analyze social and economic factors like income, food security and the rates of stunted growth connected to chronic malnutrition in children.
- One reason that MPAs benefit local and Indigenous communities is that no-take zones reach their carrying capacity as fish populations grow and recover, creating “spillover” into waters without fishing restrictions.

Study reveals turtles’ millennia-old food affair with North African seagrass
- Researchers have traced the 3,000-year-old “food footprints” of endangered green sea turtles around the Mediterranean.
- By comparing turtle bone samples from Bronze and Iron Age archaeological sites to skin samples from turtles they’re tracking by satellite today, they’ve uncovered turtles’ enduring preference for the same sea meadows.
- The findings highlight the importance of protecting these underwater meadows, which face degradation due to conversion, pollution and climate change.

‘The deep sea is vital to protect the ocean’: Q&A with France’s Hervé Berville
- In November, France took a strong position on deep-sea mining by declaring that this future activity should be banned in international waters. The nation has also banned it from its national waters.
- Berville also said he wants to make sure there is a “coalition in favor of a principle of precaution or moratorium.”
- Member states of the International Seabed Authority, the UN-associated mining regulator, recently agreed to push back its timeline for finalizing rules that would enable deep-sea mining to start.
- Mongabay’s Elizabeth Claire Alberts interviewed Berville at the French Embassy in Kingston, Jamaica, during the meeting of the ISA assembly in July.

Plastic ‘Frankenrocks’ pose new pollution threat to coastal environment
- Scientists are finding more evidence of a new, insidious form of plastic pollution: melted plastic that has melded with rocks, coral and other naturally occurring material in coastal areas.
- Samples of these “Frankenrocks” collected from a single beach on a single island in Indonesia were likely formed by the burning of plastic trash.
- They pose a danger to marine life because they can break down into microplastics that then enter the food chain, and can also leach toxic chemicals into the environment.
- Scientists have called for more study into this new and growing phenomenon, saying these Frankenrocks require specialized cleanup management to ward off a “serious problem.”

The endless struggle to clean up Rio de Janeiro’s highly polluted Guanabara Bay
- Once a nursery for marine life, Guanabara Bay in Rio de Janeiro is now dying from the dumping of thousands of liters of sewage into its waters; artisanal fishers now survive by picking up the garbage that floats in the bay.
- Faced with failed promises of de-pollution by the government, civil society organized itself, creating areas of environmental protection and pressuring the companies responsible for basic sanitation in the state, which is still deficient today.
- On the shores of the Rodrigo de Freitas lagoon, a biologist started replanting the mangroves; life returned and the site has become a model of what can be done to save the Guanabara Bay.

Deep-sea mining meetings conclude after stalemate on key agenda items
- Negotiations by member states of the International Seabed Authority (ISA), a U.N.-associated regulator, broke down at a crucial meeting in Kingston, Jamaica, before delegates reached a partial compromise in the final hours.
- The point of contention was whether to discuss two proposals at the meeting: one to conduct a review of the ISA itself and the other to discuss the possible consequences to the marine environment from a rule on deep-sea mining.
- The previous week, member states of the ISA council, the organization’s policymaking body, agreed to aim for July 2025 to finalize rules, regulations and procedures to govern deep-sea mining.
- Deep-sea mining has not yet begun anywhere in the world, but the potential impacts of this activity have stirred controversy.

‘Mud, muck and death’: Cambodia’s plan to obstruct trawlers and revive local fishing
- On Cambodia’s coast, a local NGO is building concrete underwater structures in an effort to deter destructive illegal trawlers that kill most everything in the habitat.
- The structures also serve as artificial reefs that provide small nurseries for fish, sponges, grasses and other species.
- An ambitious government plan will erect the structures near 25 fishing communities along the country’s coastline in a bid to revive Cambodia’s nearshore marine fisheries, besieged by years of destructive illegal fishing and increasing development.
- If successful, the plan could bring an influx of funding to fishing communities hit hard by the destruction of marine habitats and loss of income that have forced many to leave in search of other work.

Deep-sea mining rules delayed two more years; mining start remains unclear
- Member states of the International Seabed Authority (ISA) are currently meeting in Kingston, Jamaica, to discuss the future of deep-sea mining in international waters.
- These current meetings were highly anticipated because they coincided with the expiration of a rule that could have enabled deep-sea mining to start in the near future.
- On July 21, nations intensely negotiated an agreement to finalize regulations for deep-sea mining by July 2025, although this timeline is not legally binding.
- While companies can now technically apply for mining licenses, experts say the new agreement may make it more difficult for these to be approved before the mining regulations are finalized.

Seaweed farmers in eastern Indonesia struggle in a changing climate
- Seaweed farmers in Indonesia are losing out on revenue from their harvests as a result of erratic weather patterns and warming waters — signs of climate change impacts.
- The warming seas encourage the growth of a bacteria that attacks the commercially valuable Eucheuma cottonii species of seaweed.
- To avoid this, farmers are harvesting their crops earlier, before the seaweed grows to the optimal size, giving them a smaller yield and lower revenue at the market.
- The farmers have devised some workarounds to adapt to the situation, but say these solutions can’t be sustained in the face of a changing climate.

Scientists: Fishing boats compete with whales and penguins for Antarctic krill
- Scientists and campaigners recently documented huge krill fishing vessels plowing through pods of whales feeding in Antarctic waters, a permitted practice they say deprives the whales of food.
- As Antarctic waters warm due to climate change, krill numbers are declining, stressing wildlife that rely on the small crustaceans at the bottom of the food chain.
- The intergovernmental body in charge of regulating the krill fishery, the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), has taken specific steps to protect penguins and seals but not whales.
- At the same time, CCAMLR has stalled on the establishment of new marine protected areas and the adoption of new conservation measures. A special meeting to advance protected areas concluded June 23 with no progress.

Clean me a river: Southeast Asia chokes on Mekong plastic pollution
- New research shows that the drift of microplastics from the Mekong River to the coastlines of countries around the South China Sea depends on variable factors, including seasonal changes in winds and ocean currents.
- The Philippines is most exposed to plastic waste that mainly drifts from the Mekong River to the sea during the monsoon season, with 47% of the stranded particles ending up on its coast, followed by Indonesia at 24%, Vietnam at 17%, and Malaysia at 8%.
- Environmental advocates say the findings of this study underscore the importance of international cooperation in combating plastic pollution, which harms marine biodiversity and coastal economies.

West African fishers strike for fair wages and ‘respect’ on EU-owned vessels
- African fishers, mostly from Senegal and Ivory Coast who work on dozens of EU vessels that operate in West Africa and the Indian Ocean, took part in a strike that lasted from June 5-8, alleging wage violations.
- Vessels owned by EU companies are allowed to fish in foreign countries’ waters through agreements between the EU and the host nations. However, a third of such vessels operating in West Africa use flags of other countries and evade labor rights provisions agreed to under these pacts.
- Fishers who participated in the strike told Mongabay they were fighting for more than fair wages, saying that African sailors were not treated with respect on European boats despite doing some of the most arduous jobs.
- Seafarers’ unions called off the strike after the Senegalese government initiated negotiations with vessel owners and unions. Talks are expected to conclude in five months.

Tag team effort brings tech to aid leatherback turtle conservation
- In Puerto Rico, scientists and conservationists are deploying drones and satellite tags to gather data about leatherback sea turtles.
- Leatherback sea turtles, the largest species of turtles in the world, have seen their populations decline due to poaching, habitat loss and bycatch in fishing nets.
- Two teams are now collaborating to use drones to identify nesting sites in Maunabo in Puerto Rico.
- They’re also tagging the animals to understand more about their migration patterns once they leave the nesting beach.

Calls grow to put the brakes on deep-sea mining as countries discuss rules
- Deep-sea mining is facing growing opposition from various countries, including Canada, Sweden, Ireland and Switzerland, as well as the U.N. human rights chief and a major seafood industry group.
- On July 10, the International Seabed Authority (ISA), the U.N.-associated deep-sea mining regulator, began a set of highly anticipated meetings in Kingston, Jamaica, to discuss adopting mining regulations.
- Commercial deep-sea mining has not yet begun. One firm previously said it intended to apply for a mining license later this year, adding urgency to the discussions.
- Mining companies say it’s necessary to mine the deep sea to extract minerals for renewable technologies; scientists and other experts say seabed minerals aren’t required for these technologies, and this mining could cause irreparable damage to the marine environment.

How to ‘flip’ a paper park: Success in the North Sea carries lessons
- A recent study found that 27% of surveyed marine protected areas (MPAs) were likely “paper parks” that fail to confer real ecological protection.
- There are different kinds of paper parks, including those with overly permissive rules and those where the rules are not followed or enforced.
- Discussions among conservationists have turned to how to “flip” paper parks to make them more effective. This can require changing park rules, often only through sustained pressure on governments, or improvements in MPA management, which can be costly.
- It’s a crucial time for figuring out how to make MPAs more effective; in December, nearly 200 countries signed a landmark agreement to conserve 30% of Earth’s land and sea by 2030, committing to more than triple MPA coverage within seven years.

Keep it down: U.N. report lists ways to reduce ocean noise pollution
- A new report published by the U.N.’s Convention on the Conservation of Migratory Species of Wild Animals (CMS) outlines possible solutions to human-caused ocean noise that impacts marine life.
- It focuses on three main types of underwater noise: shipping, seismic air gun surveys, and pile driving.
- Lindy Weilgart, the report author, said she believes it’s essential to move toward finding solutions rather than only studying the impacts of human-caused ocean noise.
- An outside expert praised the report but also questioned the likelihood of the suggestions being followed, and argued that the noise impacts of wind turbines have not been fully considered.

Deep-sea expedition reveals rare octo-nurseries off Costa Rica
- A scientific expedition in June found two new deep-sea octopus nurseries on two different low-temperature hydrothermal vent sites off the west coast of Costa Rica — two of only three known deep-sea octopus nurseries in the world.
- On a previous expedition in 2013, scientists had found a group of brooding octopuses at one of these vents, but didn’t detect any babies. But in June 2023, scientists did find octopus babies.
- Researchers theorize that the brooding octopus are attracted to the rocks, warmth, or microbes at these sites.

Study finds locally managed marine areas in Fiji yield mixed results
- A study found that Fijian communities engaged in the country’s locally managed marine areas network, known as FLMMA, exhibited strengths in the mechanisms believed to advance conservation efforts, such as community participation in decision-making and financial support.
- However, it also found that FLMMA villages didn’t necessarily experience improved economic well-being, wealth, food security or even better ecological outcomes for marine resources.
- The authors say they hope the results will encourage practitioners to reassess community-based marine management projects to understand how they can be modified for success.
- Fiji has one of the most extensive LMMA networks in the world, collectively covering more than 10,000 square kilometers across the country’s territory.

Indonesia to expand ‘smart fisheries’ program aimed at empowering communities
- Indonesia will expand its smart fisheries village program, aiming to empower fishing communities to boost their productivity, achieve sustainability standards, and improve their overall economic welfare.
- Twenty-two fishing communities are enrolled in the initial batch of the program, which will focus primarily on fisheries, but also look to improve community welfare through tourism, public health interventions, financial literacy, and other initiatives.
- The participating communities are involved in catching or farming a wide range of seafood and other products, from octopus and tilapia to shrimp and organic salt.
- The fisheries sector employs about 12 million Indonesians, with most of the fleet today, about 650,000 vessels, operated by small-scale and traditional fishers.

Indonesia to cut tuna harvest in bid for more sustainable fishery
- Indonesia will reduce its overall tuna catch by 10% over the course of three years, citing unsustainable current levels of fishing.
- The government is also pushing for more tuna fisheries in Indonesia to obtain sustainable certification and eco-labeling, as part of wider efforts to show that it can manage the species within its waters.
- Fisheries experts have welcomed the move to protect the world’s tuna populations, but say other countries in the region should also be encouraged to reduce their catch to make it effective.
- Indonesia catches more tuna than any other country, accounting for about 16% of the world’s total tuna supply.

‘No future’: Iceland cancels whale hunt over animal welfare concerns
- Citing animal welfare concerns, Iceland has suspended its whale hunting season until Aug. 31.
- This decision follows the release of a government-commissioned independent report that found that many whales suffer immensely after being harpooned.
- Iceland had been set to kill around 200 fin whales, up from the 148 it killed in 2022.

Science and culture join forces to restore 120 miles of Hawaiian reefs
- A new program in Hawai‘i, known as Ākoʻakoʻa, will focus on restoring 193 kilometers (120 miles) of coral reefs off the west of the Big Island, which have been in decline for the past 50 years.
- A key aspect of the program will be the building of a new research and coral propagation facility in Kailua-Kona on the Big Island.
- While the program will be largely science-driven, it will also rely on the traditional knowledge of community leaders and cultural practitioners.

Indonesia looks into tuna farming to boost aquaculture, reduce overfishing
- Indonesia is developing tuna farming in the country’s bays in an effort to boost its aquaculture sector and ease the pressure on its world-leading marine tuna fishery.
- The fisheries ministry said it was consulting with international fisheries experts about implementing tuna farming.
- Indonesia’s archipelagic waters are key fishing grounds for several many tuna species, as well as spawning grounds for the fish.
- Indonesia’s tuna fisheries is an important source of livelihood for coastal communities and a key source of food for consumers around the world.

Europe’s top science panel supports call for moratorium on deep-sea mining
- The European Academies’ Science Advisory Council has announced its support for a moratorium on deep-sea mining.
- In a new report, the council conveys its skepticism that deep-sea mining is necessary to meet the needs of critical minerals for renewable technologies.
- It also points out that deep-sea mining would cause irreparable harm to marine ecosystems, and that the mining regulator lacks a scientific definition of what qualifies as serious harm.
- Many European nations and companies currently possess licenses to explore the international seabed for resources, although exploitation has yet to begin.

A Southeast Asian marine biodiversity hotspot is also a wildlife trafficking hotbed
- A recent report documents the seizure of 25,000 live animals and more than 120,000 metric tons of wildlife, parts and plants from the Sulu and Celebes seas between 2003 and 2021.
- The animals trafficked include rays, sharks and turtles, mostly between Indonesia, the Philippines and Malaysia, for which the region forms a maritime border zone.
- The people of the Sulu and Celebes seas region have strong transboundary cultural and trade links, prompting experts to call for enhanced international cooperation in enforcement efforts.

Indonesia eyes enrolling more ports in fight against illegal fishing
- Only four of Indonesia’s nearly 2,500 ports implement the Port State Measures Agreement (PSMA), an international treaty that targets illegal, unreported and unregulated (IUU) fishing by denying access to vessels engaged in that practice.
- With neighboring Thailand having 26 ports that implement PSMA, the Indonesian government says it’s considering expanding coverage to more of its ports.
- The PSMA is part of a set of tools to improve fisheries transparency and traceability, which in turn would increase global trust in fish products coming from Indonesia, one of the world’s top producers of seafood.
- Indonesia’s estimated fish stock is 12 million metric tons, down almost 4% from 2017, while 53% of its fisheries management zones are considered “fully exploited,” up from 44% in 2017.

Expedition to Pacific ecosystems hopes to learn from their resilience
- An expedition led by National Geographic’s Pristine Seas project will voyage across the Pacific over five years to gather information about marine ecosystems needing protection.
- The Pristine Seas team will collaborate with Pacific island nation governments, communities, Indigenous and local peoples, and local scientists, to gather data and produce films.
- The first stop of the expedition will be the southern Line Islands, part of Kiribati, to understand how its reefs recovered after an El Niño triggered a large-scale bleaching event in 2015 and 2016.

Illegal trawling ravages Tunisian seagrass meadows crucial for fish
- The largest remaining seagrass meadows in the Mediterranean are in Tunisia’s Gulf of Gabès, a hotspot for biodiversity and fishing.
- But illegal bottom trawling and industrial pollution are destroying this unique habitat, a natural nursery to numerous species of fish and other marine fauna.
- Hundreds of trawlers ply their trade overtly with little consequence, and most of the catch makes its way to Europe, skirting laws designed to prevent the entry of illegally caught seafood.

Melting Arctic sea ice is changing bowhead whale migrations, study finds
- Research has found that some bowhead whales in the Bering–Chukchi–Beaufort (BCB) population are no longer migrating to the northwestern Bering Sea in the winter but remain in the Canadian Beaufort Sea.
- These migratory shifts are occurring as sea ice declines in the region due to climate change.
- These changes could mean that bowhead whales become more susceptible to ship strikes, underwater noise, and entanglements, and that Indigenous communities may not be able to rely on bowhead whales for nutrition and cultural subsistence.
- However, this bowhead population is currently not threatened, and these changes may not be fully impacting Indigenous communities yet.

Study: Indonesia’s extensive network of marine reserves are poorly managed
- Indonesia has put nearly a tenth of its waters under some form of protection, and intends to expand this to nearly a third by 2045.
- However, a study has found that none of Indonesia’s existing marine protected areas demonstrates effective and sustainable management, and that the government is off-pace to reach its 30% target by 2045.
- Key challenges in the effective management shortcomings, the study says, are lack of funding and poor financial planning for the MPAs.
- Indonesia is home to some of the most diverse marine life on the planet, which plays an important role in the domestic and global supply of seafood.

Studies show oyster reef restoration can work out well — given enough time
- Researchers have found that the restoration of eastern oyster (Crassostrea virginica) reefs in the U.S. have been largely successful, improving oyster production, enhancing habitat, and increasing nitrogen cycling.
- They also found that oyster restoration was more successful in deeper, saltier parts of coastal waters and that it generally took at least eight years for restored reefs to yield long-term benefits.
- But since the 1800s, more than 85% of global reefs have disappeared due to overfishing, disease and other anthropogenic pressures.
- Researchers say their findings can help restoration managers identify which ecosystem services can benefit from their work, how long those benefits might take to accrue, where to construct oyster reefs.

Sargassum surges in Mexico: From nuisance to new green industry?
- Since 2011, sargassum has worsened as a nuisance — possibly due to an influx of synthetic fertilizers into the Atlantic Ocean — with the brown algae washing up on Caribbean beaches where it rots, stinks like rotten eggs and devastates tourism, including in Mexico where 30 million go for beach holidays annually.
- Sea currents have made the beaches of the Mexican state of Quintana Roo a leading arrival point for the annual surge. So early on, scientists, members of civil society, politicians and businesspeople worked together to find solutions and turn the huge waste problem into an opportunity for new green businesses.
- Once cleaned of heavy metals, microplastics, sand and other detritus, sargassum is finding many uses, particularly as biogas, but also biofertilizer, cellulose packaging and even artificial vegan leather. But a national law regulating sargassum remains elusive, with the issue tangled up in Mexican bureaucracy.
- Debate is ongoing as to who should pay for disposal, for expensive recollection and transport of the algae. As entrepreneurs experiment, Mexico has become a regional leader in creating a sargassum industry, with other Caribbean nations seeking to learn from Mexico’s business mistakes and copying its successes.

Ecuador to boost protection of Galápagos in biggest debt-for-nature deal ever
- Ecuador has launched a debt-for-nature deal that will wipe out some $1 billion in interest payments in exchange for boosting its protection of the waters around the Galápagos Islands.
- Much of the funding will focus on managing the newly established Hermandad Marine Reserve, the existing Galápagos Marine Reserve, and sustainable fishing and climate resilience efforts.
- The deal would also finance an endowment to generate ongoing funding for marine conservation in the Galápagos Islands.
- This is the world’s largest debt-for-nature deal to date.

Seabird conservation mostly works, comprehensive new data set shows
- Researchers compiled a data set of seabird restoration projects, including those that used translocation and social attraction, from around the world.
- Ornithologist Stephen Kress pioneered translocation and social attraction, but these methods have been used more than 850 times in the last 70 years — mostly to great success.
- Experts say seabirds are one of the most threatened bird groups in the world, and translocation and social attraction can help protect them against threats like invasive species and the impacts of climate change.

Philippines a global hotspot for giant clams — and their illegal trade
- Giant clams, which can grow to weigh more than 200 kilograms (440 pounds), have long been traded for their shells, which are carved into decorative items, as well as for food and the aquarium trade.
- An analysis by the NGO TRAFFIC has found that giant clams are threatened by “both a sizeable legal trade and a parallel illegal trade that is much larger than we know.”
- TRAFFIC identified the Philippines as a hotspot of the illicit trade giant clam shells, accounting for more than 99% of all seizures linked to Southeast Asia despite laws prohibiting their harvest or trade.
- The NGO has called on governments to more closely monitor the trade in giant clams, and to scale up investigations into the networks that facilitate the illegal trade.

Seafloor life abounds around hydrothermal vents hot enough to melt lead
- A team of international scientists on board the RV Falkor (too), a research vessel operated by the Schmidt Ocean Institute, recently discovered active hydrothermal vents on the Mid-Atlantic Ridge.
- This discovery was the first in more than 40 years for a 700-kilometer (423-mile) stretch of the Mid-Atlantic Ridge.
- Researchers say hydrothermal vents help regulate global ocean chemistry, support complex ecosystems, and store vast amounts of marine genetic resources.
- However, there is already interest in mining the sulfide deposits of hydrothermal vent systems for their commercially valuable minerals.

Hawaiian communities restore Indigenous conservation, from mountains to sea
- In Hawai’i, an Indigenous stewardship and conservation system known as ahupua’a is slowly being revived on a mountain-to-sea scale in partnership with U.S. government agencies.
- Three Indigenous communities that have successfully reintroduced the ahupua’a system are seeing some conservation successes, such as a 310% increase in the biomass of surgeonfish and an increase in the Bluespine unicornfish (Naso unicornis) population.
- The inclusion of Indigenous Hawaiian conservation, social and spiritual values, like Aloha kekahi i kekahi, have been key to building these conservation areas and forming better working relations with the government.

Kelp forests contribute $500 billion to global economy, study shows
- New research suggests that kelp forests generate up to $562 billion each year by boosting fisheries productivity, removing harmful nutrients from seawater, and sequestering carbon dioxide.
- The findings suggest that kelp forests are about three times more valuable than previously believed, contributing the equivalent of Sweden’s entire GDP to the global economy.
- However, experts say that kelp forests are generally overlooked and undervalued, and that many of these ecosystems are under threat worldwide.

At the United Nations, Indigenous Ryukyuans say it’s time for U.S. military to leave Okinawa
- Opponents of the latest U.S. military base in Okinawa, Japan, are calling for urgent intervention by the United Nations to halt the construction of the new base, release military groundwater test data on toxic spills, and close all 32 U.S. military bases.
- The new facility and other military bases have been linked to toxic environmental pollution and construction threatening marine species, along with historical land conflicts between native Okinawans and the mainland Japan and U.S. governments.
- Latest water tests by the Okinawa government reveal PFAS levels up to 42 times higher than Japan’s national water standards with contamination found in drinking and bathing water for roughly 450,000 people.
- Amid rising tensions with China and efforts to counter its influence in the region, Japan and the U.S. cite Okinawa’s proximity to Taiwan and location in the Indo-Pacific as a strategic reason for maintaining bases on the island.

Norway proposes opening Germany-sized area of its continental shelf to deep-sea mining
- Norway has proposed opening up a Germany-sized part of the Norwegian Sea to deep-sea mining.
- The area holds considerable quantities of minerals needed for renewable energy technologies, such as magnesium, cobalt, copper, nickel and rare-earth metals.
- The Norwegian government and industries say they will take a precautionary approach to this deep-sea mining.
- However, critics say plans should be progressing more slowly to properly assess the marine environment and the possible impacts of mining, and the Norwegian government received numerous responses during a public consultation period arguing that the country should not mine its deep sea.

Bringing the ocean’s vast ‘awesomeness’ to light: Q&A with Farah Obaidullah
- “The Ocean and Us,” edited by ocean advocate Farah Obaidullah, provides information from more than 35 female experts on various topics related to the ocean.
- These cover, among others, climate change, overfishing, pollution, ocean management schemes, the human relationship with the ocean, and inclusion and diversity in the ocean space.
- The book helps fulfill the aims of “ocean literacy,” a concept identified by the United Nations as a key driver for achieving the U.N. Decade of Ocean Science for Sustainable Development outcomes.
- “The Ocean and Us” was published by Springer Nature in February 2023.

Uterine implants and underwater ultrasounds aim to demystify shark births
- For years, studying the reproductive biology of sharks has depended on capturing the animals and dissecting them.
- Scientists recently developed the Birth Alert Tag, an egg-shaped satellite transmitter that can be implanted in the uterus of pregnant sharks to document the location and timing of births.
- In another development, scientists took ultrasound readings of whale sharks and sampled their blood to detect if they were pregnant.
- The new methods aim to help researchers determine sharks’ pregnancy status and the location of shark births; one goal is to inform the establishment of corridors to protect the animals, which are among the most vulnerable vertebrates on Earth.

Deep-sea mining meeting closes without resolving whether mining can start in July
- Delegates to the International Seabed Authority (ISA), the U.N.-associated body responsible for regulating deep-sea mining in international waters, recently met to discuss a possible start of this activity in the near future.
- While some member states support the adoption of regulations that would permit mining to commence, other nations have expressed concerns with the process.
- Observers of the meeting say there is no agreement on whether the ISA will permit mining to begin and that delegates didn’t have sufficient time to discuss the issue at the meetings, which ran March 7-31 in in Kingston, Jamaica.
- In July 2021, Nauru triggered a “two-year rule” that could obligate the ISA to allow mining to start within 24 months, no matter what regulations are in place.

‘Manta grid’ provides a ray of hope against industrial bycatch threat
- Most species of manta and devil rays (genus Mobula) are endangered, yet industrial purse seine fishing vessels unintentionally catch about 13,000 each year while hunting tuna, according to one scientific estimate.
- New regulations, handling techniques and equipment aim to reduce this number.
- Fishers are working with scientists to return the rays, which are slippery and can weigh as much as a small car, back into the sea when they are brought on deck in fishing nets.
- At the same time, experts warn that far more mobulids die in gillnets set by small-scale and semi-industrial local fishers in countries throughout the tropics.

As oceans warm, temperate reef species edge closer to extinction, study shows
- New research found that most Australian shallow reef species, including fish, corals, seaweeds and invertebrates, experienced population declines over a decade, mainly in response to warming events driven by human-induced climate change.
- While scientists recorded species decline across Australian waters, some of the most pronounced changes occurred on the temperate reefs of southern Australia, a region that has received less conservation attention than tropical reefs.
- The authors say temperate reefs could be in greater danger of extinction than tropical species, leading to calls for increased conservation efforts for these threatened ecosystems.

Can we control marine invaders by eating them?
- The Mediterranean Sea is home to more than 750 exotic species. Some have adverse ecological effects, like lionfish and blue crabs, but are also edible and even tasty.
- Observers often argue that eating invasive marine species is the best way to deal with them, but some scientists warn that this doesn’t always offer a straightforward solution.
- Setting up targeted fisheries to control marine invaders involves balancing many considerations: fishers’ interests, markets, government policy and conservation.
- Even so, harvesting and serving marine invasive species has immense power to raise awareness about them.

When a red snapper is more than just a fish: Q&A fisheries scientist Elle Wibisono
- Fisheries scientist and artist Elle Wibisono recently published a children’s book, “A Snapper Tale,” that features red-colored snappers native to Indonesia’s waters.
- Equipped with her extensive knowledge and experience in marine conservation and sustainable fisheries, Wibisono uses her book to highlight the importance of fish identification, a key component of sustainable fisheries.
- Indonesia is home to one of the world’s richest marine ecosystems, with its fisheries sector supplying seafood demand from home and around the world.
- Mongabay’s Basten Gokkon spoke with Elle Wibisono recently about her book and the highlighted fisheries issues, and her hopes for the impacts it will have on readers young and old and on Indonesia’s marine conservation policies.

Rule change sees foreign investors back in Indonesia’s fisheries scene
- The Indonesian government on March 6 issued a decree on a fisheries policy change that ushers in quota-based capture in six fishing zones for industrial, local, and non-commercial fishers.
- The policy also allows foreign investment back into the country’s marine capture sector, after it was banned in 2016 in an effort to tackle illegal, unreported and unregulated (IUU) fishing by foreign vessels in Indonesian waters.
- These key changes have raised concerns among some marine conservationists and defenders of artisanal fishers’ rights, who say the new regime is oriented mostly toward the large-scale exploitation of Indonesia’s marine resources when more than half of fishing zones in the country are already “fully exploited.”
- Indonesia is one of the world’s biggest marine capture producers, with some of the richest marine biodiversity on the planet.

As U.N. members clinch historic high seas biodiversity treaty, what’s in it?
- On March 4, U.N. member states reached a landmark agreement on a legally binding treaty aimed at protecting the international waters of Earth’s oceans.
- The deal, more than 15 years in the making, was finalized after talks overran their two-week schedule into a final, grueling 36-hour negotiation marathon.
- Delegates reached consensus on multiple thorny matters, including a framework for establishing and maintaining a network of marine protected areas on the high seas and mechanisms to share benefits from high seas resources fairly among nations.
- For the new high seas treaty to be implemented, delegates must officially adopt the treaty text at an unscheduled next meeting, and then a minimum of 60 states must ratify it, a process that could take months or years.

Will new bottom trawling rules do enough to protect South Pacific seamounts?
- The South Pacific Regional Fisheries Management Organisation (SPRFMO) is an intergovernmental body that regulates fishing across the vast international waters of the South Pacific Ocean.
- At a meeting in Manta, Ecuador, in February, the SPRFMO changed its rules around bottom trawling, a controversial fishing practice that involves dragging fishing gear along the seabed, running roughshod over any organisms or structures in its path.
- The new rules mandate the protection of at least 70% of species that indicate the presence of so-called vulnerable marine ecosystems, such as sponge fields and cold-water coral communities.
- However, conservationists have decried the new rules, calling them less protective than the current policy, let alone the ban on trawling seamounts they’ve been asking for.

China-funded bridge threatens Paradise Reef in southern Philippines
- Samal Island, a popular tourist destination near Davao City in the southern Philippines, is fringed by a 300-meter (980-foot) coral system known as Paradise Reef, which hosts more than 100 coral species.
- A plan to build a bridge linking Davao to Samal threatens to destroy the reef, scientists and conservationists warn.
- Campaigners in the area are calling on the Philippine government to reroute the bridge to minimize damage to the ecosystem.

Panama ocean conference draws $20 billion, marine biodiversity commitments
- The eighth annual Our Ocean Conference took place in Panama March 2-3.
- Participants made 341 commitments worth nearly $20 billion, including funding for expanding and improving marine protected areas and biodiversity corridors.
- One key announcement came from Panama, which said it would protect more than 54% of its marine region.

Indonesian fisheries fee change promises more revenue, but likely also more violations
- The Indonesian fisheries ministry is implementing a new scheme under which operators of large fishing boats would pay a range of fees after landing their catch instead of before.
- The ministry says the change is meant to boost state revenue from these non-tax fees, but observers warn it opens the potential for an increase in unreported catches.
- That’s because a key feature of the new policy is that it relies heavily on self-declarations by fishing boat operators when reporting the volume of their catch at port.
- Indonesia has one of the biggest fishing industries in the world, employing about 12 million mostly artisanal fishers, and its waters support some of the planet’s highest levels of marine biodiversity.

Reef ruckus: Fish fights erupt after mass coral bleaching, study finds
- An international team of researchers studied the behavioral changes among butterflyfish on a series of reefs in the Indo-Pacific before and after the 2016 global mass coral bleaching event.
- They found that following the bleaching event, fish behaved more aggressively toward one another in their newly degraded reef home.
- The energetic toll of encounters involving fighting and chasing one another could have implications for the long-term survival of reef fish species, the study authors conclude.
- Given rates of ocean warming and predictions for more frequent and intense coral bleaching over the longer term, it’s unclear whether reef fish have the capacity to adapt their behavior to their rapidly changing environments.

Experts pushing for high-seas fishing ban win ‘Nobel Prize for environment’
- Fisheries experts Daniel Pauly and Rashid Sumaila have won the 2023 Tyler Prize for Environmental Achievement, an award administered by the University of Southern California.
- The prize has been referred to as the “Nobel Prize for the environment” and comes with a $250,000 award to be shared between the two laureates.
- Both Pauly and Sumaila have said they would like to use the prize opportunity to spread the message that it’s necessary to ban all fishing on the high seas, those parts of the ocean that don’t fall under any national jurisdiction.

‘They’re everywhere out there’: Three new nautilus species described
- Researchers have described three new species of nautilus found in the Coral Sea and the South Pacific.
- The three species can be differentiated due to genetic structure, shell size and coloration, and geographic location.
- Scientists generally know very little about nautiluses but are working to fill in the data gaps to understand how to protect them.
- Nautiluses are highly threatened by the shell trade, as well as pollution and the impacts of climate change.

End of the tuna FAD? Indonesia hopes so, but EU isn’t giving up just yet
- Indonesia has welcomed measures to cut back on the use of fish-aggregating devices, which critics blame for Indian Ocean tuna being caught at unsustainable rates.
- A senior Indonesian fisheries official says all countries on the Indian Ocean coast have a shared interest in tackling the overuse of FADs and in improving the conservation and management of the region’s tuna populations.
- In 2022, the Indian Ocean’s bigeye tuna population was declared overfished, while repeated violation of catch limits for skipjack tuna was reported.
- The European Union, whose fleet accounts for a third of the Indian Ocean tuna catch, has reportedly said it will object to the new resolution; in that event, its vessels will simply continue deploying FADs as usual, since the new measure isn’t enforceable.

On Lombok, rising sea levels force fishers into different jobs
- Residents of the Indonesian island of Lombok say sea levels are rising at alarming levels, swallowing seaside towns.
- People are abandoning their family trade of fishing to instead grow seaweed or leave the island for stable employment.
- The provincial government created a climate adaptation task force to address the compounding problems of climate change, as families send their children to school and hope they choose a life different from fishing.

Fishing communities create marine refuges to protect Chile’s biodiversity
- In Chile’s Valparaíso region, artisanal fishers have created grassroots marine reserves to protect marine biodiversity.
- The areas are small, some of them just 15 hectares (37 acres) in size, but they provide a haven for marine creatures to grow and reproduce.
- This growth can contribute to regenerating coastal biodiversity, making the region more resilient to climate change, while the fisherfolk can benefit from a greater availability of resources in the long term.

Potential impact on whales overlooked as deep-sea mining looks set to start, experts say
- Scientists say future deep-sea mining activities could impact cetaceans through noise pollution, which could interfere with their communication processes.
- According to an opinion piece, a team of experts say assessments of deep-sea mining impact have focused on species associated with the seabed rather than transitory megafauna that inhabit the proposed mining areas, and that urgent research is needed to understand the potential impact on cetaceans.
- However, a mining company says it is evaluating the potential impact of its proposed operations on cetaceans through the gathering of acoustic data during its recent mining test in the CCZ, which it will combine with three years of environmental baseline data.
- Deep-sea mining in international waters may begin later this year after the Pacific island nation of Nauru, which sponsors a subsidiary of a Canadian mining firm, requested accelerated approval of its mining operation.

Study: Paying fishers to ease off sharks and rays is cost-effective conservation
- Paying fishers in Indonesia to not catch sharks and rays could be a cost-effective way of conserving these species, a new study suggests.
- Interviews with fishers at two sites shows that payments of $71,408-$235,927 per year could protect up to 18,500 hammerheads and 2,140 wedgefish at those sites.
- Researchers say this money could come from dive tourism levies, and they are already carrying out a pilot project that has seen fishers release more than 150 hammerheads and wedgefish in eight months.
- An independent expert cautions that there need to be safeguards to prevent a perverse incentive where fishers are deliberately catching these species just so they can release them and claim payment.

Good fisheries management, if enforced, can help sharks and rays recover
- Effective fisheries management, strong regulations, enforcement, and monitoring can help conserve sharks and rays, according to new research.
- Researchers found that some shark populations in the northwest Atlantic recovered after the U.S. implemented a management plan in 1993, despite ongoing fishing, while populations in areas without sufficient management declined.
- A previous study found that overfishing threatens one-third of sharks, rays and chimeras with extinction, making them the second-most endangered vertebrate group, after amphibians.

An El Niño is forecast for 2023. How much coral will bleach this time?
- Forecasts suggest that an El Niño climate pattern could begin later this year, raising sea temperatures at a time when global temperatures are already higher than ever due to human-driven climate change.
- If an El Niño develops and it becomes a moderate to severe event, it could raise global temperatures by more than 1.5°C (2.7°F) above pre-industrial levels, the threshold set by the Paris Agreement.
- An El Niño would generate many impacts on both terrestrial and marine ecosystems, including the potential for droughts, fires, increased precipitation, coral bleaching, invasions of predatory marine species like crown-of-thorns starfish, disruptions to marine food chains, and kelp forest die-offs.

Thai government turns its sights on illegal coral trade
- For years, Thailand has focused on curtailing its illegal trade in terrestrial wildlife.
- Recently, the country has begun trying to do the same for marine coral species, primarily those caught up in the ornamental aquarium trade.
- New laws, higher penalties for breaking them, beefed-up enforcement and a national mandate to curtail illegal coral trade are all part of Thailand’s efforts to end the trade in its corals.
- While authorities have made several arrests, they have yet to bust any high-profile coral traders.

Mongabay Explains: What’s the difference between artisanal and industrial fishing?
- A new episode of “Mongabay Explains” examines the difference between artisanal and industrial fishing.
- Broadly speaking, artisanal fishing is a form of traditional fishing that uses relatively small, low-powered boats to make short trips close to shore and catch relatively small quantities of fish, whereas industrial fishing uses large vessels that make longer trips farther out to sea and catch larger volumes of fish.
- There are plenty of other differences between the two fishing sectors, too, including their relative impact on the marine environment.
- In this video, Mongabay explores the differences between the two forms of fishing, including some ways people are trying to make each sector more sustainable.

Indonesia opens its ‘ocean account’ for sustainable marine management
- The Indonesian government is designing a new scheme to measure over time the benefits provided by the country’s marine and coastal ecosystems for sustainable ocean management.
- The ocean accounting system will become the standard indicator for the government in policymaking and zoning when it comes to the country’s fisheries, conservation areas, and marine essential ecosystems such as seagrass meadows, mangrove forests and coral reefs.
- Indonesia’s ocean account initiative is also part of an international collaboration under the Global Ocean Accounts Partnership (GOAP), which aims to “develop globally recognized and standardized methods for ocean accounting by 2023.”
- Indonesia has partnered with another GOAP member, Norway, on long-term technical cooperation on ocean accounting.

Indigenous Kawésqar take on salmon farms in Chile’s southernmost fjords
- Sixty-seven salmon farms exist within Kawésqar National Reserve in southern Chile, an area that formed part of the Kawésqar Indigenous people’s ancestral lands, and another 66 concessions are under consideration there.
- The salmon industry claims the farms only occupy 0.06% of the reserve, which covers a marine area of 2.6 million hectares (6.4 million acres), and have a legitimate presence in the area.
- But Kawésqar communities accuse the farms of taking up the fjords where their sacred areas and fishing grounds are, of violating their rights on their own territory, and of compromising the ecosystem of the entire reserve through severe pollution.
- Kawésqar communities, with the support of various NGOs, are pursuing numerous legal avenues aimed at excluding salmon farms from the reserve.

U.S. refuses calls for immediate protection of North Atlantic right whales
- The U.S. government has rejected requests to implement emergency measures to protect critically endangered North Atlantic right whales from vessel collisions during the species’ calving season, which takes place between November and April each year.
- Some protections for right whales are already in place, but experts say urgent modifications are needed to protect pregnant females, lactating mothers and calves.
- There are only about 340 individual North Atlantic right whales left in the world, and birth rates are low.
- The National Marine Fisheries Service has proposed similar protections for right whales, including the enforcement of speed limits across more extensive areas of the ocean and for the rules to apply to more vessels — but charity workers are cautious about the outcome of this proposal.

Re-carbonizing the sea: Scientists to start testing a big ocean carbon idea
- Ocean alkalinity enhancement (OAE) involves releasing certain minerals into the ocean, sparking a chemical reaction that enables the seawater to trap more CO₂ from the air and mitigating, albeit temporarily, ocean acidification.
- Some scientists believe OAE could be a vital tool for drawing down and securely storing some of the excess CO₂ humanity has added to the atmosphere that is now fueling climate change.
- Yet many questions about OAE remain, including most prominently how it would impact marine life and ecosystems.
- Several programs are aiming to spark the research needed to answer these questions, including field tests in the ocean.

As sea lice feast away on dwindling salmon, First Nations decide the fate of salmon farms
- Increased sea lice infestations, scientists say are caused by salmon farms, threaten the already-vulnerable wild Pacific salmon populations in western Canada, worrying conservationists and First Nations.
- Three First Nations in the region are now deciding on the future of open net pen Atlantic salmon farms dotting the channels and waterways in and around their territories. They hope their decisions will pave the way to protect wild salmon, a culturally important species.
- So far, ten farms have been closed and the future of seven farms are to be decided this year, in 2023.
- The impact of the closure of the farms on local sea lice and wild salmon populations is still unclear, say scientists, and more time to monitor the data is needed.

Study aims to unmask fishing vessels, and owners, obscured by loopholes
- A new study reveals information about the shifting identities of the global fishing fleet, which can help tackle illegal, unreported and unregulated fishing (IUU) fishing.
- The research combines a decade’s worth of satellite vessel tracking data with identification information from more than 40 public registries to generate a first-of-its-kind global assessment of fishing compliance, foreign ownership of vessels, and reflagging.
- It found that nearly 20% of high seas fishing was likely unregulated or unauthorized, and that the reflagging of vessels, which operators may do to avoid oversight, mainly took place in ports in East Asia, West Africa and Eastern Europe.
- The researchers plan on making a broader data set publicly available soon and regularly updating this data so that authorities have access to timely information.

Invasive rats topple ecological domino that affects reef fish behavior
- A recent study reveals that the presence of invasive rats on islands can lead to behavioral changes in fish living on coral reefs offshore. A team of scientists found that damselfish have larger territories that they defend less aggressively on reefs near rat-infested islands.
- Rats and other rodents often tag along on ships. For hundreds of years, they’ve colonized islands around the world, where they feast on seabird chicks and eggs, decimating local populations.
- Seabirds deposit nutrient-rich guano on islands, some of which flows out to reefs and fertilizes the growth of algae.
- Smaller seabird numbers on rat-infested islands mean that fewer nutrients end up on reefs, and the algae there has lower nutritional value than off rat-free, seabird-rich islands. The study’s authors concluded that damselfish were less aggressive near islands with rats because it wasn’t worth the energy to defend a less valuable resource.

More marine protected areas planned for Indonesia’s Maluku after 2022 spree
- The Maluku Islands in Indonesia will protect more swaths of their seas this year, following from the designation of five marine protected areas in 2022 alone.
- The new protected areas will cover the waters around the western island of Buru, where fishing activity will be limited to traditional fishers using sustainable gear.
- Indonesia currently has 284,000 square kilometers (110,000 square miles) of marine area under protection, roughly two-thirds of its target of protecting 10% of its waters.
- The Maluku Islands sit within the Pacific Coral Triangle, an area renowned for its richness of corals and reef fish.

Island conservation should focus on land-sea links for most impact, paper says
- A new perspective piece in PNAS explores the idea that people, wildlife and the environment of islands thrive when conservation efforts focus on restoring both the land and sea together.
- One way to restore land-sea connections on islands is to eradicate invasive species, such as rats, which can harm native island species like seabirds and crabs.
- Research has shown that terrestrial and marine ecosystems reap benefits when invasive species are eliminated from islands.

Sharks received landmark protection to combat fin trade, but the culling must stop (commentary)
- CITES CoP19 marked a historic win for shark conservation and the fight against the global trade in shark fins and meat, but an equally critical issue that must be tackled is shark culling.
- For many decades, popular culture and media, through the choice of words and visual depictions, have portrayed sharks as a threat to humans. Several countries actively kill sharks in mass numbers to control their presence near beaches.
- While shark nets and drumlines can separate the sharks from the humans at beaches, they aren’t fully effective. There are new methods that use technology, like electric shark repellents and magnetic and visual stimuli, work better to prevent human-shark encounters.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Indonesian ‘island auction’ to go ahead despite concerns over permits
- Shares of a private company with the rights to develop tourism facilities within a marine reserve in Indonesia have reappeared for auction later this month despite the government’s plan to annul an agreement with the firm.
- The government plans to revoke developer PT LII’s 2015 memorandum of understanding with local authorities, including the rights to develop the Widi Islands for 35 years with a possible extension of another 20 years.
- The company’s plan has met mounting concerns in Indonesia, with experts saying it would be essentially selling the islands off to foreigners and cutting off local fishing communities from a key source of livelihood.
- The Widi Islands are also part of a marine reserve in the Pacific Coral Triangle, a region that’s home to the highest diversity of corals and reef fishes in the world.

Democratizing the deep sea: Q&A with Ocean Discovery League’s Katy Croff Bell
- The current expense of studying the deep seas stymies many research initiatives, so scientists have developed a low-cost imaging and sensor device to make access to the deep sea more equal.
- Developed using off-the-shelf hardware, “Maka Niu” can capture images and collect data on temperature and salinity down to a depth of 1,500 meters, or nearly a mile.
- Scientists in countries like the Maldives, Seychelles and South Africa are now deploying prototypes to provide feedback for the final product.

Restoring Hong Kong’s oyster reefs, one abandoned oyster farm at a time
- Conservationists and researchers are teaming up to restore oyster reefs across Hong Kong.
- At one site, they are repurposing concrete posts from an abandoned oyster farm that made use of traditional oyster cultivation methods dating back hundreds of years.
- Hong Kong’s oysters, and its oyster farmers, are threatened by development, warming and acidifying marine waters brought on by climate change, and toxic algae blooms due to pollution.
- By restoring the reefs, conservationists and scientists hope they can improve water quality, stabilize shorelines, and provide habitat for the city’s surprisingly rich marine wildlife.

Indonesia’s ‘essential’ mangroves, seagrass and corals remain unprotected
- Much of Indonesia’s mangrove forests, seagrass beds and coral reefs fall outside protected areas, according to a recently published report.
- Indonesia currently has 284,000 square kilometers (110,000 square miles) of marine area under protection, and plans to expand the size of its MPAs to 325,000 km2 (125,000 mi2) by the end of this decade, or 10% of its total territorial waters.
- Less than half of seagrass and coral reefs, and less than a fifth of mangroves, lie within currently protected areas, which experts say could thwart efforts at effective marine conservation.
- The country is home to some of the most diverse marine life on the planet, especially in its eastern region that falls within the Pacific Coral Triangle, an area renowned for its richness of corals and reef fish.

2022’s top ocean news stories (commentary)
- Marine scientists from the University of California, Santa Barbara, share their list of the top 10 ocean news stories from 2022.
- Hopeful developments this past year include the launch of negotiations on the world’s first legally binding international treaty to curb plastic pollution, a multilateral agreement to ban harmful fisheries subsidies and a massive expansion of global shark protections.
- At the same time, the climate crises in the ocean continued to worsen, with a number of record-breaking marine heat waves and an accelerated thinning of ice sheets that could severely exacerbate sea level rise, underscoring the need for urgent ocean-climate actions.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

Hunting for future-proof marine plants in the acidic waters bathing a volcano
- The naturally acidic seawater near an underwater volcano in Italy mimic pH levels that according to worst-case climate projections will be common by the end of the century and beyond.
- Scientists are studying local seagrass and seaweed responses to the acidic conditions.
- One question is whether they could be used for restoration purposes in other places that may become more acidic in a not-so-distant future.
- Even so, some researchers point out that these carbon-sequestering marine plants face more immediate challenges from pollution, habitat degradation and warming waters that need addressing for restoration to succeed.

Mongabay Explains: What’s all the brouhaha over bottom trawling?
- A new episode of “Mongabay Explains” examines the controversial fishing method known as bottom trawling, in which vessels drag a net across the seafloor to scoop up bottom-dwelling marine life.
- Ever since the 14th century, fishers who use other gear types — later joined by conservationists and scientists — have objected to bottom trawling, saying the gear takes too many fish and destroys seafloor habitat that’s essential to the functioning of marine ecosystems.
- Proponents of bottom trawling, however, argue that the practice provides an important share of our seafood as well as numerous jobs, and cannot be abandoned.
- In this video, Mongabay takes a look at bottom trawling and the reasons it’s so controversial.

Unsustainable fishing to be banned in Irrawaddy dolphin’s Bornean sanctuary
- Indonesia’s fisheries ministry is working with a conservation NGO to draw up plans prohibiting fishing gear considered dangerous to critically endangered Irrawaddy dolphins in the Mahakam River in Borneo.
- The prohibition will apply to a stretch of the Mahakam that was designated a conservation area earlier this year and that’s home to 90% of the estimated 80 Irrawaddy dolphins in the Mahakam.
- Among the practices they’re seeking to ban are fishing with a type of gill net known as rengge, electrofishing, poison fishing, and fixed-net fishing known as sawaran and kombongan.
- Local fishers are said to be supportive of the plan: “They want to continue fisheries but they also want to get rid of unsustainable fishing … because they care about the dolphins as well.”

Strong marine protected areas credited with manta ray surge in Indonesia
- Manta ray populations are thriving in Indonesia’s Raja Ampat archipelago, a new population assessment shows, highlighting the importance of marine protected areas to the species’ conservation.
- The study showed that reef manta ray (Mobula alfredi) populations saw up to 10.7% compound annual increase from 2009-2019 in the region, even as global ray and shark populations undergo a sweeping decline.
- The study authors attribute this to well-planned and -implemented conservation measures by Indonesian authorities, conservation groups and local communities.
- The finding chimes with the discovery earlier this year that manta ray populations are also flourishing in Komodo National Park, another tightly regulated protected area in Indonesia.

Plastic pellet pollution can end through coordinated efforts, report shows
- Tiny plastic pellets called nurdles are a major source of global pollution, littering waterways, harming ecosystems and threatening marine life.
- But plastic pellet pollution is preventable, according to a new report by the international conservation group Fauna & Flora International (FFI), and it’s one piece of the global plastic problem that can and should be tackled.
- Solving the problem will require coordinated efforts by companies, governments and the International Maritime Organization (IMO), according to FFI.

Extinct sea cow’s underwater engineering legacy lives on today, study finds
- In a new study, scientists said that the extinct Steller’s sea cow impacted kelp forests in the North Pacific by browsing at the surface, which would have encouraged the growth and strengthening of the algal understory.
- Not only would sea cows have positively impacted kelp forests in the past, but they may have also enhanced their resilience into modern times, according to the authors.
- Globally, kelp forests face many threats, including ocean warming, which can lead to an overabundance of predatory urchins.
- The authors suggest that it might be possible for humans to reproduce the species’ impact on the canopy of kelp forests to enhance kelp forest resilience.

Black Sea dolphin deaths prompt ecocide allegations against Russia
- On Dec. 7, Ukrainian President Volodymyr Zelenskyy accused Russia of ecocide during COP15, the U.N. biodiversity summit in Montreal, following unprecedented reports of dead dolphins and porpoises washing up on Black Sea beaches since Russia invaded Ukraine.
- On Dec. 2, researchers reported the first scientific analysis of changes in cetacean deaths and movement patterns since the war began in February.
- Mounting evidence is slowly painting a clearer picture of the mass mortality of Black Sea cetaceans.
- But estimates of the death toll vary and scientists diverge on whether research has progressed far enough to scientifically conclude the war’s effect.

Island shopping: Cambodian officials buy up the Cardamoms’ coast
- A buying spree by Cambodia’s wealthy and politically connected elites has put the fate of a string of small islands in the balance, affecting the livelihoods of local fishers.
- Resort developments threaten the Koh S’dach archipelago’s seagrass and coral ecosystems, which harbor rare and threatened marine life.
- Local fishers have also found themselves locked out of their traditional fishing grounds by the developers, leading to a loss of earnings.
- This story was supported by the Pulitzer Center’s Rainforest Investigations Network where Gerald Flynn is a fellow.

Dalian Ocean Fishing, subject of Mongabay probe, now sanctioned by U.S.
- The U.S. Department of the Treasury’s Office of Foreign Assets Control recently announced sanctions on Chinese individuals and companies allegedly involved in human rights abuses and illegal, unreported, and unregulated (IUU) fishing while operating in distant waters.
- One sanctioned company, Dalian Ocean Fishing Co., Ltd. (DOF), was the subject of two Mongabay investigations: one uncovered widespread human rights abuses, and the other exposed extensive illegal shark-finning operations within the DOF fleet of longline fishing vessels.
- China, which operates the world’s largest distant-water fishing fleet and has a long history of fisheries offenses, denounced the sanctions, saying that it is a “responsible fishing country.”

Peat on land and kelp at sea as Argentina protects tip of Tierra del Fuego
- Argentinian legislators recently approved a law to permanently protect the Mitre Peninsula at the tip of South America, which harbors vast peatlands and kelp forests that host an assortment of species.
- The Mitre Peninsula is thought to hold about 84% of Argentina’s peatlands, which are known to sequester about 315 million metric tons of carbon dioxide, roughly equivalent to three years of emissions in Argentina.
- The region also holds more than 30% of the world’s kelp forests, another key store of carbon.

Shark-fishing gear banned across much of Pacific in conservation ‘win’
- The Western and Central Pacific Fisheries Commission has outlawed shark lines and wire leaders, both of which aid industrial-scale fishers in targeting sharks.
- Shark numbers in the open ocean have dropped by roughly 71% in the past 50 years.
- Proponents consider the measure a potentially precedent-setting move that could precede similar bans in other regions.

Indonesian authorities nip island auction in marine reserve in the bud
- Indonesian officials have sought to neuter an apparent bid to auction off private tourism enclaves to foreign investors in a marine reserve in the country’s east.
- Shares of Bali-based developer PT Leadership Islands Indonesia (LII) had been up for bidding via Sotheby’s Concierge Auctions in New York from Dec. 8-14, but the deputy environment minister said this had now been annulled.
- LII holds the rights to develop tourism facilities in the Widi Islands, but not to sell off individual islands to foreign investors, which is against Indonesian law.
- The Widi Islands are part of a marine reserve in the Pacific Coral Triangle, and while most of the islands are uninhabited, they hold high social, cultural and livelihood importance for local fishing communities.

Fishers in Flores Sea opt to limit harvest of overexploited sea cucumbers
- Fishers on Indonesia’s Sapuka island have decided to regulate their sea cucumber harvests.
- Since the 1960s, sea cucumber has been an important commodity for the island, but heavy harvest pressure has pushed the fishery to overexploited status.
- Sea cucumbers play a crucial role in the marine ecosystem by providing food to other species and adding nutrients and pH balance in waters around coral reefs and other shallow-water ecosystems.

Illegal bottom trawling widespread inside Mediterranean marine protected areas
- A new “atlas” reveals widespread illegal bottom trawling inside Mediterranean marine protected areas.
- The atlas, an interactive online map, shows thousands of days of apparent bottom-trawling activity in areas where it is banned, in 2020 and 2021.
- Bottom trawlers can damage the seabed, destroy coral and sponge habitats, and catch unintended species at a high rate.
- The findings demonstrate “the lack of enforcement and transparency in the Med, which is the most overfished sea in the world,” an atlas coordinator told Mongabay.

No requiem for sharks just yet as nations push to protect species from trade
- Nations party to CITES, the global convention on the trade in endangered species, are supporting three proposals to list dozens of sharks and rays from three families onto Appendix II of the convention.
- While a CITES Appendix II listing would not prohibit trade outright, it would regulate it by requiring export permits, which would help mitigate overexploitation.
- A recent study found that more than a third of sharks, rays and chimeras are threatened with extinction, making them the second-most threatened vertebrate group, after amphibians.
- The proposals are up for discussion at CITES’s 19th Conference of the Parties, or CoP19, taking place from Nov. 14-25 in Panama.

France’s Macron joins growing chorus calling for deep-sea mining ban
- On Nov. 8, French President Emmanuel Macron became the first head of state to call for a complete ban on deep-sea mining, an activity that would extract industrial quantities of minerals from the seabed in international waters in the near future.
- Delegates of the International Seabed Authority (ISA) are currently meeting in Kingston, Jamaica, to discuss deep-sea mining regulations, and many member states are using this forum to express their concerns about mining going ahead.
- In June 2021, the Pacific island nation of Nauru, which sponsors Nauru Ocean Resources Inc. (NORI), a subsidiary of Canadian firm The Metals Company (TMC), triggered a “two-year rule” that could force the ISA to allow mining to go ahead in two years with whatever regulations are in place.

Negotiations to conserve Antarctic Ocean end in stalemate on many issues
- The 41st annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with conserving marine life in the Southern Ocean and managing fisheries there, ended Nov. 4 with little progress made on several key issues.
- In 2009 CCAMLR committed to creating a network of marine protected areas to preserve Antarctic ecosystems. It established one that year and another in 2016, but since then China and Russia have repeatedly blocked the creation of additional protected areas, as well as other conservation-related measures.
- The commission also failed to reach the consensus required to enact new regulations for the krill and toothfish fisheries, or to protect a vast nesting area for icefish discovered earlier this year.
- CCAMLR members did agree to designate eight new vulnerable marine ecosystems, areas home to slow-growing organisms such as corals, sponges, brittle stars and feather stars that are now permanently protected from bottom fishing.

Did climate change really kill billions of snow crabs in Alaska?
- In October 2022, the National Oceanic and Atmospheric Administration (NOAA) announced that the lucrative snow crab fishery in the Bering Sea would close for the first time, following a population decline of 80% between 2018 and 2022.
- While fisheries managers and biologists say climate change is to blame for the species’ retreat, some fishers and crab experts suggest that trawling bycatch and other fishing activity may have played a role in the snow crab’s decline.
- The fishery’s closure has amplified a chorus of concerns about Alaska’s trawling industry and the knowledge gaps around its potential impact on fisheries.

Small island, big ocean: Niue makes its entire EEZ a marine park
- In April, Niue, a small island nation in the South Pacific Ocean, designated its entire exclusive economic zone — an area about the size of Vietnam — as a multiple-use marine park called Niue Nukutuluea.
- Forty percent of the park is a no-take marine protected area; a smaller slice is managed by local villages. And about 56% of the park is a general-use zone where commercial fishing and other activities, including possibly deep-sea mining, could take place.
- The country has developed an unusual mechanism to fund the park, and is gathering support to confront the perennial challenge of monitoring and compliance in technologically advanced ways.

New Zealand convicts company of illegal trawling in high seas restricted area
- In late August, a court in Aotearoa New Zealand convicted a subsidiary of one of the country’s major seafood companies of illegal trawling in a closed area in the Tasman Sea between New Zealand and Australia.
- The judge fined the company NZ$59,000 (about $33,000) and the skipper NZ$12,000 (about $7,000), and seized the vessel.
- It’s the fourth case in the past five years where courts convicted New Zealand-flagged vessels of illegal trawling.
- The recent conviction comes amid an ongoing debate about trawling in New Zealand, with campaigners calling for a ban on bottom trawling on submarine mountains, and the industry disputing their arguments and resisting aspects of the proposed change.

Deep dive uncovers previously unknown underwater ecosystem in Maldives
- Scientists recently identified a previously undiscovered marine ecosystem in the waters around the Maldives, known as the “trapping zone,” about 500 meters (about 1,600 feet) below the surface.
- The researchers say the trapping zone refers to a region of subsea vertical cliffs and shelving terraces that “trap” small, migrating mesopelagic organisms, which attract pelagic predators like sharks, tuna and large fish.
- Prior to this mission, very little was known about the Maldivian sea below 30 m (about 100 ft), despite the country’s total area consisting 99% of water.
- The researchers say trapping zones likely exist in the waters around other oceanic islands with similar topography, and that they’re already gathering evidence of such an ecosystem in the waters of the Chagos archipelago, south of the Maldives.

Why fish are disappearing from Amazonian waters
- From the coastline to freshwater streams, people living in Amazonia say industrial fishing, deforestation, hydroelectric dams and climate change have reduced fish populations.
- Industrial fishing is one of the main explanations for the low numbers. Fishermen report that large boats are trawling with nets up to 30 kilometers (18.6 miles) in length that do not allow fish to reach the shore.
- Other challenges local fishers are facing have to do with the effects of climate change on rivers and mangroves, including increased temperature and lower pH and oxygen levels in the water, which make it harder for species to survive.
- Hydroelectric dams are a threat to inland Amazonian fish species because they interrupt migratory flow, leading to genetically compromised populations; this phenomenon has been seen in the Xingu River, which, dammed by the Belo Monte hydroelectric plant, is suffering from falling fish reproduction rates.

Wrong trend for right whales amid ‘devastating’ population decline
- A newly released estimate suggests that only 340 critically endangered North Atlantic right whales remained as of 2021, a 2.3% decline from 2020, when the population numbered around 348.
- Fewer calves have been born in 2022 so far, corroborating research that suggests that North Atlantic right whale species are becoming less capable of reproducing.
- No adult mortalities have been recorded in 2022, but experts say that only about a third of whale deaths are recorded.

Europe considers large-scale seaweed farming; environmental effects unknown
- The European Commission is planning large-scale industrial farming of seaweed across the continent’s shores.
- The goal is to farm 8 million metric tons of seaweed annually by 2030, up from the current annual farmed production of about 3,000 metric tons.
- Proponents tout a sustainable form of farming that can produce food, chemicals, pharmaceuticals and biofuels, and sequester carbon.
- However, the potential ecological impacts have yet to be fully assessed.

To boost fish catches, try banning fishing, new study shows
- A new study has found that the Papahānaumokuākea Marine National Monument in Hawai‘i, the world’s largest contiguous marine protected area, increased the catch rates of yellowfin and bigeye tunas in nearby fisheries due to a “spillover effect.”
- Between 2016 and 2019, catches of yellowfin tuna increased 54% in waters near the MPA, and catch rates for bigeye tuna rose by 12%.
- Another study found that MPAs not only increase the catches for fisheries, but also yield other benefits, like the enhancement of carbon sequestration and biodiversity.
- However, both studies suggest that the best results come from fully protected MPAs that don’t allow fishing, and that underprotected MPAs yield “little to no social or ecological benefits.”

Fish-feed industry turns to krill, with unknown effects on the Antarctic ecosystem
- The Antarctic krill fishing industry has been growing in the past two decades.
- The global growth of fish farming is driving the demand for Antarctic krill as an alternative to wild fish in fish feeds, amid the depletion of many wild fish stocks.
- Independent scientists say the krill fishery could have a detrimental effect on Antarctica’s predator populations, which are also suffering from the impacts of global warming.
- The krill industry is expanding its fleet and planning to significantly increase catches in the next few years.

Shallow-water mining isn’t the eco alternative to deep-sea mining, study says
- Mining in the shallow waters of the continental shelf is seen as more sustainable than deep-sea mining, but goes against global goals on sustainability and conservation, a new study says.
- There are already shallow-mining projects underway in Namibia and Indonesia; others, in Mexico, New Zealand and Sweden, have been proposed.
- But as with deep-sea mining, for which commercial operations have not yet begun, shallow-water mining can have drastic effects on marine biodiversity because it requires dredging up the seafloor to extract the minerals found there.

Proposal to grant the ocean rights calls for a sea change in legal framework
- In 2022, the professional sporting group the Ocean Race launched a bid to establish the Universal Declaration of Ocean Rights (UDOR).
- The proposed legal structure would give the ocean legal rights within a multilateral governance system.
- While some laws protect parts of the ocean, there is currently no framework to specifically recognize the ocean’s inherent rights on a national or international level.
- Various countries have already voiced their support for the UDOR, including Monaco, Cabo Verde and Panama.

Panama restricts information on sanctioned boats, evading transparency
- Over the course of three months earlier this year, Mongabay and Bloomberg Línea requested information from the Panamanian authorities concerning inspections carried out on Panama-registered boats and the resulting sanctions that were imposed.
- Panamanian authorities denied much of the request, claiming it concerns information of a restricted nature.
- The authorities did grant a request to review vessel records at the location where they are held, but prohibited the reporting team from taking photographs or making photocopies. The team found paper records arranged in thick folders with pages in neither ascending nor descending order, which made the search a complex task.
- Lawyers who specialize in fishing and environmental issues say the authorities should release the information, and that the difficulty accessing it hinders efforts to uncover illicit activities.

As Indonesia protects more marine areas, top priority is management: experts
- As Indonesia aims to protect more of its seas, scientists say in a new paper that effective management of these marine areas must be the government’s top priority in a world faced with global climate change and biodiversity crises.
- The researchers say that marine protected areas must protect the natural resources, provide long-term benefit to local people, and be equipped with a zoning system, monitoring, surveillance, adequate staff capacity, facilities, and self-financing.
- The Indonesian government has pledged to secure 10% of the country’s territorial waters towards biodiversity protection and sustainable use by the end of this decade, and triple the size by 2045.
- The move is part of the country’s contribution to the global “30 by 30” conservation goal, which aims to protect 30% of the world’s seas and lands by 2030.

Panama: A ‘flag of convenience’ for illegal fishing and lack of control at sea
- Why would a Chinese ship want to fly the Panamanian flag? This practice is known as flying a “flag of convenience” and although it’s legal, experts say it often lets shipowners benefit from lax auditing and is closely associated with illegal fishing because it can hide the identity of a vessel’s true owners.
- Mongabay Latam and Bloomberg Línea investigated violations and alleged crimes committed by the fleet of ships flying the flag of Panama, the country whose flag is most commonly used.
- Our analysis of an official database shows that some of the vessels operating under the Panamanian flag do business with a Chinese company that has one of the global fishing industry’s longest criminal records.

A ‘super reef’ recovery raises hopes — but also questions about its resilience
- Experts documented the substantial recovery of coral reefs around the southern Line Islands in the central Pacific after the area was hit by a large-scale coral bleaching event in 2015 and 2016.
- Many factors may have contributed to the reef’s recovery, including the fact that the reef is seemingly untouched by human activity, which helped maintain a healthy and resilient ecosystem.
- But other experts question whether this reef would be able to recover after more frequent bleaching events, which are predicted to increase as global temperatures continue to rise.

Mangroves and wildlife in Bornean bay at risk from Indonesia’s new capital
- Experts and activists say the construction of Indonesia’s new capital city upstream of Balikpapan Bay on the island of Borneo fails to mitigate against damage to the marine ecosystem.
- The stretch of coast between the bay and the mouth of the Mahakam River is packed with mangroves, which host a rich diversity of marine and terrestrial life, including proboscis monkeys and Irrawaddy dolphins.
- The government has said the construction of the new capital, Nusantara, will include retaining a large swath of mangrove forest, but zoning details show most of it won’t be protected against development.
- The $33 billion planned city will in 2024 take over as the Indonesian capital from Jakarta, and its full construction will be completed by 2045, according to the government’s plans.

Greenland shark, world’s longest-living vertebrate, gets long-awaited protection
- In September, the Northwest Atlantic Fisheries Organization (NAFO), an intergovernmental organization that manages fisheries, prohibited the retention of Greenland sharks in international waters.
- This ban would apply to the intentional catching of Greenland sharks as well as the retention of the species as bycatch.
- However, bycatch exceptions could be made if countries prohibit the discarding of fish.
- Greenland sharks are known to be the longest-living vertebrate in the world, reaching ages of between 270 and 500 years.

Indonesian program pays fishers to collect plastic trash at sea
- The Indonesian fisheries ministry has launched a four-week program to pay fishers to collect plastic trash from the sea.
- The initiative is part of wider efforts to reduce Indonesia’s marine plastic pollution by 70% by 2025.
- The country is a top contributor to the plastic trash crisis in the ocean.
- Each of the 1,721 participating fishers will receive the equivalent of $10 a week for collecting up to 4 kg (9 lbs) of plastic waste from the sea daily.

Podcast: ‘Destructive & flawed’: Claire Nouvian on bottom trawling’s many impacts
- Goldman Environmental Prize winner Claire Nouvian joins the Mongabay Newscast to discuss the many impacts of bottom trawling and a historic policy shift by the European Commission to rein in the practice.
- This kind of fishing is known for damaging deep-water coral reef ecosystems and marine biodiversity, and for having a heavy carbon footprint.
- Nouvian discusses the successful activism of her organization that won an EU-wide ban on bottom trawling below 800 meters (875 yards) after seven years of grassroots organizing. She also discusses what individuals can do if they want to support more sustainable fishing practices.

‘One more thing’ about plastics: They could be acidifying the ocean, study says
- New research suggests that plastic could contribute to ocean acidification, especially in highly polluted coastal areas, through the release of organic chemical compounds and carbon dioxide, both of which can lower the pH of seawater.
- The study found that sunlight enabled this process and that older, degraded plastics released a higher amount of dissolved organic carbon and did more to lower the pH of seawater.
- However, the findings of this study were conducted in a laboratory, so it’s unclear whether experiments conducted in estuaries or the open ocean would yield similar results, experts said.

Indonesian lobster larvae bound for Singapore reveal role of smuggling network
- Two recent seizures of lobster larvae shipments destined for Singapore have prompted an investigation by Indonesia into a smuggling network operating between the two countries.
- The shipments had an estimated value of $2.2 million, and were the latest in a string of attempts to smuggle the larvae to buyers in Singapore, Vietnam and China.
- Indonesia has banned the export of wild-caught larvae in an effort to its lobster stocks, and is encouraging the growth of the domestic lobster-farming industry.
- Lobsters are among Indonesia’s top fisheries commodities, but the illegal exports cost the country $64 million in lost revenue in 2019 alone, according to official data.

Indonesia’s sustainable fisheries push sails into storm in Java Sea
- Civil society activists have questioned whether a sanctioned alternative to the seine net will help fish stocks recover in Indonesia’s fishing zones.
- Fishers on Java’s northern coast are struggling to adapt to sustainability changes announced by Indonesia’s fisheries ministry.
- Cases of conflict between seine net fishers and smaller local fishing boats continue to be reported.

Java fishers struggle with seine net ban amid rising costs, falling profits
- Fishers on the north coast of Java are struggling to adapt to a ban on the seine net, with many boats confined to port after the government ceased issuing new permits to seine net fishers.
- Java fishers report declining catch volumes from the alternative net.
- Some boat captains fear bankruptcy as cash flow pressures mount.

Indonesia to update conservation efforts for aquarium favorite cardinalfish
- Indonesia’s fisheries ministry says it is working on a new conservation road map for Banggai cardinalfish (Pterapogon kauderni), a popular species in the aquarium trade globally that is found only in the waters around the country’s Banggai Archipelago.
- The fish is caught in large numbers — an estimated 500,000 to 900,000 individuals annually — and is exported mainly to the United States and Europe.
- The updated conservation plan will evaluate the previous five-year plan for the cardinalfish, and use this to inform the national strategy for the next five years, the ministry said.
- The cardinalfish’s habitat, the Banggai Archipelago, is considered to be in the heart of the Pacific Coral Triangle, which is home to the highest diversity of corals and reef fishes anywhere on the planet.

U.S. charts course for adopting ropeless fishing to reduce whale deaths
- The National Oceanic and Atmospheric Administration (NOAA) has published a report laying out a strategy to allow the use of “ropeless” or “on-demand” fishing gear off the U.S. East Coast with the goal of reducing entanglements of the critically endangered North Atlantic right whale.
- The gear uses acoustic signals to locate and retrieve gear, reducing the amount of time that vertical lines are present in the water column, where they can ensnare right whales and other types of marine life.
- Right whale numbers in the North Atlantic have declined precipitously in the past decade, as collisions with ships and entanglements have killed individuals and hampered the species’ ability to reproduce.
- NOAA’s Ropeless Roadmap estimates that on-demand fishing gear can substantially diminish the risk to right whales, while allowing economically and culturally important fisheries of the northeastern U.S. to continue.

Sri Lankan study identifies new jellyfish, sparking interest in the species
- A jellyfish study initiated by the Wayamba University of Sri Lanka has shed light on this ignored marine species that’s rarely been studied since 1905 and contributed to increasing the possible number of jellyfish species found in Sri Lanka to about 150.
- Researchers also described a new box jellyfish species named Carybdea wayamba, also the first species of this genus described from this part of the Indian Ocean, and are working on a number of other species that are potentially new.
- Jellyfish fishery has potential in Sri Lanka and the department of fisheries has made various attempts to popularize it before, but conservationists highlight the need for proper population and distribution study before introducing the new form of fishery.
- Even though the species found in Sri Lankan waters are not lethal, the jellyfish is a medically important species as Sri Lanka records several hospitalizations each year due to stings.

Europe moves to protect deep-sea sites in Atlantic from bottom fishing
- The European Commission recently announced that it will protect 16,000 square kilometers (6,200 square miles) of the deep sea — known as “vulnerable marine ecosystems” — in EU waters in the northeast Atlantic Ocean by prohibiting bottom fishing in these areas.
- This move is a key component to the Deep-Sea Access Regulation, a plan adopted by the EC in 2016 to protect deep-sea environments in EU waters. However, the regulation stipulated that vulnerable marine ecosystems should be protected by 2018, so its implementation comes four years late.
- The fishing sector has warned that this move will threaten the future of bottom fishing and impact more than 10,000 fishers.
- Conservation experts have welcomed this announcement, despite its lateness, saying that such a move is essential in protecting fragile and ecologically important deep-sea environments.

Regulator approves first deep-sea mining test, surprising observers
- The International Seabed Authority (ISA), the intergovernmental body responsible for overseeing deep-sea mining operations and for protecting the ocean, recently granted approval for a mining trial to commence in the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean.
- The company undertaking this trial is Nauru Ocean Resources Inc (NORI), a subsidiary of Canadian-owned The Metals Company (TMC), which is aiming to start annually extracting 1.3 million metric tons of polymetallic nodules from the CCZ as early as 2024.
- The approval for this mining test, the first of its kind since the 1970s, was first announced by TMC earlier this week.
- Mining opponents said the ruling took them by surprise and they feared it would pave the way for exploitation to begin in the near future, despite growing concerns about the safety and necessity of deep-sea mining.

Sri Lanka eyes major compensation case over X-Press Pearl sinking
- Sri Lanka has received $2.5 million in the third interim payment for the sinking of the X-Press Pearl cargo ship in June 2021, giving it a total of just $7.85 million for the worst maritime disaster in the country’s history.
- These payments from the Singapore-flagged vessel’s insurer are mainly to reimburse the government for the cost of the emergency response operations and for direct damages and cleanup.
- Environmental lawyers say the government can and should pursue a much larger compensation claim for the environmental damage wrought.
- The X-Press Pearl sank off Sri Lanka’s western coast after catching fire, in the process spilling its cargo of hazardous chemicals and billions of plastic pellets that continue to dot the country’s beaches.

Acid test: Are the world’s oceans becoming too ‘acidic’ to support life?
- The world’s oceans absorb about a quarter of humanity’s carbon dioxide emissions, buffering us against higher atmospheric CO2 levels and greater climate change. But that absorption has led to a lowering of seawater pH and the acidification of the oceans.
- The process of ocean acidification is recognized as a leading threat to ocean life due to its impairment of calcifying organisms and other marine species. The full impacts of acidification are unknown, but at some point reduced pH could be disastrous biologically.
- Researchers have designated ocean acidification as one of nine planetary boundaries whose limits, if transgressed, could threaten civilization and life as we know it. But there is debate as to whether there is a global boundary for this process, since acidification impacts some regions and species more or less than others, making it hard to quantify.
- Scientists agree that the primary solution to ocean acidification is the lowering of carbon emissions, though some researchers are investigating other solutions, such as depositing alkaline rock minerals into oceans to lower the pH of seawater.

‘Mind-blowing’ marine heat waves put Mediterranean ecosystems at grave risk
- A recent study reveals the widespread effects of climate change-driven marine heat waves on the ecological communities of the Mediterranean Sea.
- Rises in sea surface temperatures as high as 5° Celsius (9° Fahrenheit) above normal have caused die-offs in 50 different taxonomic groups of animals from around the Mediterranean Basin.
- These far-reaching impacts of the warming sea could devastate the fisheries on which many of the Mediterranean region’s 400 million people rely.
- Researchers advocate bolstering and expanding marine protected areas. Although they can’t hold back the warmer waters that have proven deadly to the sea’s rich biodiversity, these sanctuaries can help ensure that these species don’t have to cope simultaneously with other pressures, such as overfishing or pollution.

In Indonesia’s West Sumbawa, tide turns on taste for turtle eggs
- Consumption of turtle eggs is widespread in Indonesia’s West Sumbawa district, where they’re served to guests of honor such as local government officials.
- All seven species of sea turtle are listed as threatened worldwide, with egg poaching a key cause of endangerment.
- West Sumbawa officials have pledged to stamp out poaching and consumption of sea turtle eggs.

Greenland’s sustainable halibut fishery may threaten newfound corals, sponges
- Industrial trawling for halibut in the Davis Strait off western Greenland is currently done in a certified sustainable manner, but new studies suggest it may be doing long-term harm.
- The studies describe assemblages of unique marine life on the seafloor both inside and near the halibut fishing zones that could potentially be considered “vulnerable marine ecosystems.”
- Scientists have called for protection of these potential VMEs, but acknowledge that ending bottom trawling altogether isn’t a viable option when fishing accounts for 93% of Greenland’s exports.
- Fishing industry stakeholders say they’re confident that existing rules designed to help the halibut fishery meet sustainability requirements will be sufficient to spare these potential VMEs, and point to a new management plan for the entire Greenlandic seabed that is in development as a way to strengthen protections.

Seaweed an increasingly fragile lifeline for Philippine farmers
- Commercial seaweed farming began in the Philippines in the 1970s and has grown to be one of the country’s most significant aquaculture enterprises, supporting more than 200,000 coastal families.
- In communities in Palawan, seaweed farming also plays a role in protecting marine life, with small farmers serving as extra eyes and ears in the fight against illegal fishing.
- As climate change intensifies, warmer waters are making seaweed farms more susceptible to pests and diseases, threatening the survival of the industry and the families that depend on it.

Maldives shark-fishing ban tested by ebbing support from small-scale fishers
- A 2010 blanket ban on shark fishing in the Maldives doesn’t enjoy support from artisanal reef fishers, a new study suggests.
- Many fishers blamed sharks for stealing their catches, eating into their earnings, and damaging their fishing equipment — problems they perceive have worsened since the creation of a shark sanctuary.
- These negative perceptions could result in lower compliance with fishing restrictions and undermine efforts to revive shark populations in Maldivian waters.
- Pole-and-line skipjack tuna fishers reported the greatest support for the shark fishing ban because sharks corral tuna to the ocean surface, making them easier to catch.

Delegates come close, but fail again to clinch high seas protection treaty
- At the close of two weeks of negotiations on Aug. 26 in New York, delegates from around the world had failed to net consensus on a high-stakes, legally binding treaty to conserve biodiversity on the high seas.
- These areas beyond national jurisdictions comprise two-thirds of the global ocean and are a vast, resource-rich global commons. Yet there is no comprehensive, agreed-upon framework governing resource extraction or conservation there.
- Top sticking points included fair access to marine resources for all and how to establish marine protected areas on the high seas.
- The meeting was the fifth of four planned diplomatic sessions that began in 2017 following more than 10 years of discussion. It ended with a commitment to reconvene before the year is over.

Three-fourths of waste in Jakarta’s notoriously polluted rivers is plastic
- Most of the waste collected from the rivers and holding facilities in Indonesia’s capital, Jakarta, is plastic, new field-based research has found.
- Researchers note that the plastic debris recovered from the surface water amounted to 9.9 grams, or a third of an ounce, per person on average, which is lower than an estimate from a widely cited 2015 study.
- The researchers have called for a better mitigation strategy to eliminate plastic pollution in rivers and subsequently the ocean.
- Indonesia, a country of more than 270 million people, is the No. 2 contributor to global marine plastic pollution, behind only China.

Indonesia announces plan to protect 10% of its seas by 2030, and 30% by 2045
- Indonesia will expand its marine protected area coverage to 325,000 square kilometers (125,000 square miles) by the end of this decade, or 10% of its total territorial waters, the fisheries ministry says.
- From 2030 to 2045, the government plans to triple that coverage to 975,000 km2 (376,000 mi2).
- An oceans conservation activist has welcomed the plan, but says the government needs to be able to square it with a recently announced fisheries management policy that critics say threatens the sustainability of fish stocks.
- The activist also emphasized the need to ensure the quality of the protection rather than the quantity.

Study paints ‘bleak picture’ for nearly all marine life without emissions cuts
- New research published in Nature Climate Change has found that nearly 90% of assessed marine life would be at high or critical risk by 2100 if the world continues upon a high-emissions pathway.
- It found that the risks would be more concentrated in the tropics, and that top predators would be more at risk than species lower down the food chain.
- However, if countries drastically reduce their emissions, the study found that climate risk would decrease for more than 98% of these species.

Scientists develop AI that can listen to the pulse of a reef being restored
- Scientists have developed a machine-learning algorithm that can distinguish healthy coral reefs from less healthy ones by the soundscape in the ecosystem.
- Previous studies had established that the sounds of life in a successfully recovered reef are similar to those from a healthy reef, but parsing all the acoustic data was slow and labor-intensive.
- The new algorithm has been hailed as “an important milestone” for efficiently processing acoustic data to answer the basic question of how to determine the progress of a reef restoration program.
- Researchers say follow-up work is still needed, including to check whether the algorithm, tested in the Pacific Coral Triangle, also works in reefs in other parts of the world.

Indonesia backtracks on plan criticized for ‘privatizing’ fisheries resources
- Indonesia will not go ahead with a plan to allow foreign and domestic fishing companies to operate for up to 30 years under a contract system.
- The plan was widely criticized by small-scale fishers and marine experts, who said it threatened to turn a public resource into a private one for the highest bidders.
- The fisheries ministry now says it will revert to a quota-based system for allocating fishing permits, under which new investors will be eligible for “special permits” of up to 15 years.
- Experts say details of the new fisheries management system must be made public, given that the “special permit” scheme looks suspiciously like the axed contract system.

Overlooked and at risk, seagrass is habitat of choice for many small-scale fishers
- Seagrass meadows, rather than coral reefs, are the fishing grounds of choice for many fishing households in four countries in the Indo-Pacific region, a new study shows.
- Fishers in Cambodia, Tanzania, Indonesia and Sri Lanka identified seagrass meadows as being more easily accessible than coral reefs, often without the need for a boat, and less likely to damage equipment such as nets.
- However, seagrasses around the world are disappearing at rates that rival those of coral reefs and tropical rainforests, losing as much as 7% of their area each year.
- The study makes the case for better-informed management of these marine habitats, to ensure their sustainability for the marine life and people who depend on them.

‘Spiderwebs’ to the rescue for Indonesia’s coral reefs
- A small-scale project in Indonesia is seeing success in efforts to restore coral reefs damaged by blast fishing.
- Lightweight cast-iron rods form underwater “spiderwebs” that are placed onto existing reefs, with new coral grafted onto the structure.
- Proponents of the project say the benefits are already tangible, but add that to make them last, there needs to be an end to destructive fishing practices.

Amid haggling over deep-sea mining rules, chorus of skepticism grows louder
- This week, the International Seabed Authority, the intergovernmental body tasked with overseeing deep-sea mining in international waters, concluded its recent set of meetings, which ran from July 4 to Aug. 4, 2022.
- The purpose of these meetings was to progress with negotiations of mining regulations, with a view that deep-sea mining will start in July 2023 after the Pacific island nation of Nauru triggered a rule that could obligate this to happen.
- While many countries appear to support the rapid development of these regulations, an increasing number of other countries have expressed concern with this deadline, indicating a possible turn of events.

Sea life may downsize with ocean warming — bringing challenging impacts
- A new model predicts that marine microbes could shrink by up to 30% in the future due to climate change, impacting bigger organisms that eat them including fish, potentially disrupting the food chain from the bottom up. Smaller fish would mean impacted fisheries. Smaller microbes could mean less carbon sequestration.
- Warmer oceans hold less oxygen, and the model predicts that sea life will get smaller in response to more limited oxygen. But scientists have long debated why this downsizing occurs, and some say that other factors not considered in the model could impact oceanic microbes in unexpected ways.
- Accurately predicting warming impacts on marine life could improve ocean resource management.

‘We’ve got to help the oceans to help us’: Q&A with deep-sea explorer Dawn Wright
- On July 12, oceanographer and geographer Dawn Wright descended 10,919 meters (35,823 feet) below the surface of the ocean to the deepest known part of the planet, Challenger Deep, alongside deep-sea explorer Victor Vescovo.
- Wright was the first Black person to make the voyage to Challenger Deep, where she and Vescovo documented several findings, including the discovery of a beer bottle on the seabed.
- The goal of the expedition was to test out a side-scan sonar designed to go down to 11,000 m (nearly 36,100 ft) that can take detailed images of the seafloor, which was successfully achieved.
- Mongabay’s Elizabeth Claire Alberts spoke to Wright before and after her expedition to learn more about the voyage’s personal significance to Wright, the challenges in venturing this far down into the ocean, and the significance of understanding more about the deep-sea.

Concerns over transparency and access abound at deep-sea mining negotiations
- Delegates to the International Seabed Authority (ISA), the U.N.-mandated body responsible for overseeing the development of deep-sea mining in international waters and protecting the ocean, are currently meeting in Kingston, Jamaica, to negotiate a set of regulations that would determine how deep-sea mining can proceed.
- Scientists and conservationists say there are many transparency issues at the current meetings, and that the ISA has restricted access to key information and hampered interactions between member states and civil society.
- However, the ISA has stated that it’s committed to transparency and that attendees have full access to the discussions.
- Deep-sea mining could begin in as little as a year with whatever regulations are currently in place.

Stingrays can ‘talk’ when they get riled up, new study suggests
- A new paper provides the first evidence that wild stingray species produce short, loud clicking sounds.
- While scientists still need to learn how and why stingrays make these noises, they speculate that the clicking sounds are a distress or defense signal.
- The paper documents three instances of this behavior in mangrove whiprays and cowtail stingrays, two species threatened with extinction.

‘The sea means everything’: Q&A with deep-sea mining opponent Debbie Ngarewa-Packer
- New Zealand parliamentarian and Māori activist Debbie Ngarewa-Packer has spent more than two decades serving in leadership roles, using her positions to advance social justice issues and to campaign for the protection of the marine environment.
- A key issue that Ngarewa-Packer is currently working on is a push to ban deep-sea mining in the global ocean, a proposed activity that would extract large amounts of minerals from the seabed.
- Ngarewa-Packer previously worked with other Māori activists, NGOs and community members to block consent for a deep-sea mining operation in her home district of South Taranaki on New Zealand’s North Island.
- In an interview with Mongabay, Ngarewa-Packer talks about why it’s critical to protect the deep sea from mining, what ancestral teachings say about protecting the ocean, and why she feels hopeful about the future.

Ban on use of destructive net fails to make an impact in Indonesia, experts say
- Fisheries observers say a year-old ban on a seine net considered unsustainable and destructive has been largely ineffective.
- Reports show fishers continue to use the square-meshed cantrang net despite the ban, and can even modify the diamond-meshed replacement introduced by the fisheries ministry.
- While in theory the replacement net should allow juvenile fish to escape, in practice it’s used much the same way as the cantrang, threatening already depleted fish stocks around the country.
- Observers blame the continued violations on authorities’ reluctance to crack down on the hugely popular cantrang for fear of angering the millions-strong and politically important demographic of fishing communities.

Study: Climate impacts to disproportionately hurt tropical fishers, farmers
- The majority of 72 coastal communities studied in five countries in the Indo-Pacific region may face significant losses of agricultural and fisheries products — two key food sources — simultaneously under the worst-case climate change projections, a new study shows.
- These potential losses may be coupled with other drivers of change, such as overfishing or soil erosion, which have already caused declining productivity, the study adds.
- But if carbon emissions can be effectively managed to a minimum, the study’s authors say, fewer communities would experience losses in both the agriculture and fisheries sectors, indicating the importance of climate mitigation measures.
- The current global average temperature is 1.1°C (2°F) above pre-industrial times, and climate experts have warned that it could climb to about 3°C (5.4°F) higher by the end of this century if nothing changes.
