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.
Undercover in a shark fin trafficking ring: Interview with wildlife crime fighter Andrea Crosta
- Worldwide, many of the key players in wildlife trafficking are also involved in other criminal enterprises, from drug smuggling to human trafficking and money laundering.
- In an interview with Mongabay, Andrea Crosta, founder of Earth League International, talks about the group’s new report on shark fin trafficking from Latin America to East Asia and the concept of “crime convergence.”
- International wildlife trafficking, including the illegal trade in shark fins, is dominated by Chinese nationals, Crosta says.
- Since smuggling routes often overlap and criminal groups frequently work together across borders, Crosta calls for field collaboration among countries and law enforcement agencies to fight wildlife crime, the world’s fourth-largest criminal enterprise.
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.
‘Our life support system is at risk’: Interview with ‘Her Deepness’ Sylvia Earle
- At the 9th Our Ocean Conference in Athens, Mongabay’s Elizabeth Claire Alberts interviewed oceanographer and marine biologist Sylvia Earle about the pressures facing our oceans, actions needed to turn things around, and how to find hope for the future.
- Earle has been a trailblazer in her career as a scientist, with more than 225 publications to her name, leading more than 100 expeditions, and breaking records as the first woman to venture into the deep ocean in a submersible and also to perform the deepest untethered sea walk.
- She’s currently president and chair of the NGO Mission Blue and an explorer-in-residence at the National Geographic Society.
- Now in her late 80s, she still spends most of her time traveling the world to inspire action to protect the ocean.
No answers for Ghanaian fishery observer’s family months after suspected death
- Samuel Abayateye, a 38-year-old father of two, was working as a fisheries observer when he was reported missing from his assigned vessel in October 2023.
- After a body missing its head, forearms and feet that Abayateye’s family says closely resembled him washed ashore in December, the Ghana Police Service opened an investigation.
- Five months later, Abayateye’s family said they still haven’t received any information from the authorities investigating the case, or the results of a DNA test to confirm the identity of the body.
- A fisheries observer told Mongabay the case has sown fear among observers appointed to monitor and report on illegal fishing in fleets operating in Ghana. Fishing industry experts say the case highlights the dangers faced by observers, whose job is critical to ensuring fishing vessels comply with the law.
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.
It will take 880 years to achieve UN ocean conservation goals, at this rate (commentary)
- Indigenous conservationist Angelo Villagomez will speak at the Our Ocean conference, one of the largest and highest profile conferences of its kind, this week in Athens, Greece.
- He plans to say that ocean conservation has lost momentum toward protecting 30% of the ocean by 2030 and that a lot more needs to be done to address the human dimensions of conservation, including guaranteeing access rights, equity, and justice.
- “At this rate, raising the area of global ocean protection from 8% to 30% will take an additional 880 years,” he argues in a new op-ed.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
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.
Island-building and overfishing wreak destruction of South China Sea reefs
- The offshore islets and reefs of the South China Sea have been the stage of intense geopolitical standoffs for decades, as the region’s coastal states compete for territorial control of the productive maritime area that includes oil and gas fields and reef and oceanic fisheries.
- A new investigation based on satellite monitoring and fisheries data reveals that overfishing, giant clam harvesting and island-building have devasted significant portions of the region’s shallow coral reefs.
- Experts say the direct loss of some of the world’s most diverse marine ecosystems is not the only cost, citing likely consequences for distant fisheries that depend on spawning grounds on some of the now-obliterated reefs.
- Actions by China and Vietnam were found to be by far the most egregious; however, experts say the onus lies on all South China Sea coastal states to work together toward solutions that will ensure the long-term protection and health of remaining reefs.
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.
Lebanese youths take up rods and reels to learn sustainable fishing
- Lebanon’s fisheries face multiple challenges, including the prevalence of illegal and destructive practices, like dynamite fishing.
- New initiatives aim to shift mentalities, particularly among the younger generation.
- One of them, run by the Lebanese NGO Friends of Nature, aims to train 300 youths across the country in sustainable fishing methods.
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.
Japan prepares to mine its deep seabed by decade’s end
- Japan is one among just a handful of nations actively pursuing deep-sea mining within its own waters.
- The country aims to be ready to mine by the late 2020s and could be among the first nations to exploit the deep sea.
- The country has completed multiple small-scale mining tests that it claims are world firsts, and it positions itself as a global leader in the “sustainable development” of deep-sea mining.
- However, concerns about the environmental impacts of deep-sea mining have prompted widespread opposition to the practice, and one critic notes that Japan’s momentum may be too great to stop for any warning signs its research might raise.
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.
Son of Cali Cartel leader tied to Colombia-Hong Kong shark fin trafficking
- Although Colombia banned the fishing and trading of sharks in early 2021, their fins — taken from sharks in Colombia and around the world — have continued to feed a global industry worth $500 million per year.
- This is the story of the largest seizure of its kind ever carried out in Colombian territory. A shipment of more than 3,400 shark fins destined for Hong Kong was intercepted at the airport in Bogotá in September 2021.
- For the first time, this investigation reveals the owner of this contraband: Fernando Rodríguez Mondragón. He is the son of the late Gilberto Rodríguez Orejuela, who was the leader of the Cali Cartel, once one of the largest drug trafficking organizations in the world.
- This investigation reconstructs the shipment’s route from the department of La Guajira, on the border with Venezuela, to Colombia’s capital, passing through the mountains in the department of Valle del Cauca.
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.
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.
Should all marine reserves ban fishing? Not necessarily, new study shows
- A new study examined the performances of two types of marine protected areas: no-take MPAs, where all fishing activity is banned, and multiple-use MPAs, which allow certain forms of fishing.
- It found that no-take MPAs increased fish biomass by 58.2%, and multiple-use MPAs increased by 12.6% compared to zones without any form of protection; the study also found that both types of MPAs were more than 97% likely to improve fish populations.
- The authors suggest that multiple-use MPAs can provide “a viable and potentially equitable pathway to advance local and global conservation” when adequately designed and managed.
- However, an expert not involved in the study suggests that MPAs with full protection are more urgently needed to protect marine ecosystems like coral reefs.
Seabird poop is recipe for coral recovery amid climate-driven bleaching
- Researchers have found that nutrients from seabird poop led to a doubling of coral growth rates and faster recovery after bleaching events, promoting overall resilience.
- Islands with invasive rats, which kill birds, saw half the coral growth rate of islands with healthy seabird populations, emphasizing the need for rat eradication to restore seabirds and nutrient flow.
- Individuals, organizations and governments can help coral reefs by better protecting seabirds, implementing and funding invasive predator control programs, restoring native vegetation, and cutting greenhouse gas emissions.
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.
Summit on migratory species sides with science, throws shade on deep-sea mining
- Representatives from 133 member states of the Convention on the Conservation of Migratory Species of Wild Animals (CMS) met in Samarkand, Uzbekistan, from Feb. 12-17 to discuss measures to protect migratory species on a global scale.
- Many decisions at the meeting, known as COP14, focused on the protection of marine species, including the listing of several species in the convention’s appendices, a draft decision on vessel strikes, and an updated resolution on climate change that urges parties to take measures to protect species from future threats.
- The convention also adopted a resolution urging parties not to engage with or support deep-sea mining until more scientific evidence is acquired. This resolution garnered criticism from the secretary-general of the International Seabed Authority (ISA), the U.N.-mandated body that governs deep-sea mining in international waters.
- While attendees say COP14 had many successes, some experts say that more action and resources are required to keeping species from sliding toward extinction.
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.
Concern for Mexico’s vaquita as totoaba swim bladder trafficking surges online
- The dried swim bladders, or “maw,” of totoaba, an endangered fish found in the Gulf of California in northern Mexico, are being increasingly trafficked on digital platforms, according to a report from the Environmental Investigation Agency (EIA).
- The demand for totoaba has impacted other animals that get caught in the same gillnets, most notably the vaquita, the smallest porpoise in the world.
- EIA’s investigation found an increase in the number of swim bladders sold online and on some social media platforms like WeChat, a Chinese texting and cash payments app.
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.
From exporting coral to restoring reefs, a Madagascar startup rethinks business
- After her father died, Jeimila Donty took over her family’s coral export business and shifted its focus to conservation, creating Koraï.
- Donty is part of a young “pro-climate” generation that’s keen to incorporate the environment into business models.
- Koraï plants corals in Madagascan waters on behalf of other companies as part of their corporate social responsibility (CSR) commitments.
- The business is ambitious and faces challenges, such as recruiting workers and a lack of political support.
Pakistan bucks global trend with 30-year mangrove expansion
- Around the world, mangrove forests have undergone a decades-long decline that is just now slowing to a halt.
- In Pakistan, by contrast, mangroves expanded nearly threefold between 1986 and 2020, according to a 2022 analysis of satellite data.
- Experts attribute this success to massive mangrove planting and conservation, as well as concerted community engagement.
- Many in Pakistan are looking to mangroves to bolster precious fish stocks and defend against the mounting effects of climate change — even as threats to mangroves, such as wood harvesting and camel grazing, continue with no end in sight.
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.
In Argentina, scientists scramble to study seal colonies hit hard by avian flu
- A powerful strain of the avian flu has swept through seal colonies in southern Argentina, wiping out many juvenile populations and raising concern about a spread to other species.
- The flu, also known as H5N1, appeared in Argentina in August 2023 and resulted in newborn mortality rates of over 90% in some seal colonies.
- Researchers are monitoring colony population trends and trying to better understand how the disease jumps from one species to another, which could affect other mammals like orcas.
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.
DNA probe uncovers threatened shark species in Thailand’s markets
- A shark DNA investigation has revealed the presence of shark species threatened with extinction in products commonly sold in Thailand’s markets.
- The study identified products derived from 15 shark species, more than a third of which have never been recorded in Thai waters, highlighting the scale of the international shark trade.
- Marine conservation groups say the findings underscore that consumers of shark fin soup and other shark products could well be complicit in the demise of threatened species that fulfill vital roles in maintaining ocean balance.
- Experts have called on Thai policymakers to improve traceability in shark trade supply chains, expand marine protected areas, and make greater investments in marine research.
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.
Palau is the first nation to ratify treaty to protect high seas
- Palau has become the first nation to ratify the high seas treaty, which seeks to protect and manage ocean areas beyond national jurisdiction.
- At least two other nations, Chile and the Maldives, appear to be on the cusp of ratifying the treaty.
- A total of 60 nations must ratify the treaty for it to take effect.
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.
AI and satellite data map true scale of untracked fishing and ocean industry
- A new study shows that more than 75% of industrial fishing activity and almost 30% of transport and energy activity in the oceans has not been tracked by public systems, revealing a significant gap in global observational data.
- The study, led by Global Fishing Watch, used AI to analyze 2 petabytes of satellite imagery collected between 2017 and 2021, providing unprecedented insights into hidden fishing hotspots and offshore energy infrastructure development.
- The research highlighted the potential of combining AI with Earth observation data to gain a more comprehensive understanding of ocean activities, which is needed to manage and improve the sustainability of the $2.5 trillion blue economy.
- The open-source code developed during the study can help inform policy for safeguarding ocean ecosystems, enforcing laws and identifying renewable energy expansion sites, the study authors said.
‘Really a sad day’ as Norway votes to allow deep-sea mining in Arctic waters
- Norway’s parliament has voted to allow deep-sea mining to commence in the Norwegian Sea, a move that has garnered criticism from scientists and environmentalists.
- While the Norwegian government insists that it can conduct deep-sea mining in a sustainable way, critics say these activities will put marine ecosystems and biodiversity at risk.
- Norway will open a 281,000-square-kilometer (108,500-square-mile) area of the ocean for deep-sea mining, which mostly falls along its continental shelf.
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.
Photos: Top species discoveries from 2023
- Scientists described a slew of new species this past year, including an electric blue tarantula, two pygmy squid, a silent frog, and some thumb-sized chameleons.
- Experts estimate less than 20% of Earth’s species have been documented by Western science.
- Although a species may be new to science, it may already be well known to local and Indigenous people and have a common name.
- Many new species of plants, fungi, and animals are assessed as Vulnerable or Critically Endangered with extinction as soon as they are found, and many species may go extinct before they are named, experts say.
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.
Peru’s ports allow entry of Chinese ships tied to illegal fishing & forced labor
- Experts say that as of October, around 75 foreign vessels, most of them Chinese, entered Peruvian ports in 2023 without carrying a satellite tracking device Peru requires of foreign fleets.
- Mongabay Latam analyzed the background of 56 vessels that entered between June and August 2023 and found that at least 10 belonged to companies with a history of illegal fishing or forced labor.
- Experts cite deficiencies in port inspections and say Chinese-flagged ships have continued to turn off their satellite systems on the Peruvian border at sea to avoid detection.
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.
Causeway threatens mangroves that Philippine fishers planted as typhoon shield
- The city of Tacloban in the central Philippines was ground zero for Typhoon Haiyan, one of the most powerful tropical cyclones ever recorded and the deadliest in the Philippines’ modern record.
- A decade after the storm, the city is moving forward with controversial plans to build a road embankment and land reclamation project that proponents say will help protect the city from storm surges.
- Opponents of the plan say it threatens local fisheries, will disrupt natural storm protection measures like mangroves, and is poorly designed as a barrier against storms.
- The plan will also result in the relocation of a coastal village of 500 households, who have been active stewards of the bay’s mangrove forests.
Marine conservation technology hub rises from old L.A. wharf (analysis)
- In 2014, the Port of Los Angeles gave a 50-year lease to an aging wharf called City Dock No. 1 to a project called AltaSea.
- AltaSea is a non-profit project founded in 2014 that in less than 10 years has become a leading ‘blue economy’ research hub focused on renewable ocean energy, sustainable aquaculture and other blue technologies.
- Hub tenants include marine renewable energy startups, sustainable aquaculture projects, a marine seed bank, a research effort aimed at decarbonizing oceanic shipping, and other projects.
- This article is an analysis. The views expressed are those of the author, not necessarily of Mongabay.
‘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.
Reef damage from 2024 Olympics surfing venue is avoidable (commentary)
- Parisians are not the only ones criticizing the 2024 Olympic Games: residents of Tahiti in French Polynesia are concerned about negative impacts on its celebrated reef from a surfing event venue being built in Teahupo’o.
- A coalition of fishermen, farmers, surfers, and citizens of Teahupo’o have started a petition and have held at least one protest in hopes of forcing Olympic organizers to change their plans.
- “If Paris 2024 intends to follow through with its promises to ‘bring about a new era’ of sustainability in the sporting world, it must take action to ensure that the Teahupo’o reef is left undamaged for its marine and human populations,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
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.
In reversal, Mexico calls for moratorium on international deep-sea mining
- On Nov. 21, Mexico became the latest nation to call for a moratorium on deep-sea mining in international waters.
- Before this announcement, some Mexican delegates to the International Seabed Authority, the UN-associated body tasked with regulating the activity, had expressed support for fast-tracking mining rules that would enable mining to start.
- This announcement came two weeks after member states of the ISA met to work on a set of regulations, which are currently far from complete.
- While calling for a moratorium on seabed mining in international waters, it remains unclear if Mexico will allow deep-sea mining in its own waters; there are several mining concessions in the Bay of Ulloa, off the coast of Baja California.
90 NGOs question Thailand Prime Minister on fisheries deregulation plan (commentary)
- Thailand’s new government is promising to “unlock” fisheries by reducing regulation and transparency around vessels’ activities.
- A letter signed by 90 NGOs questions the National Fishing Association’s proposals for fisheries reform, including returning to day-rate salaries, permitting child labor and weakening punitive measures designed to deter illegal, unregulated and unreported (IUU) fishing.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Jamaica battles relentless plastic pollution in quest to restore mangroves
- In recent decades, mangroves in Jamaica have declined rapidly, from about 15,000 hectares (37,000 acres) in the 1970s to about 9,945 hectares (24,574 acres) now.
- Currently there are several efforts to restore mangroves in the island country, as experts recognize the many ecosystem services they provide, including the protection and stabilization of coastlines as human-induced climate change worsens.
- However, restoration efforts face numerous challenges: Near Kingston, the main one is voluminous tides of plastic waste, which can stunt mangrove growth or kill them.
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.
Fisheries managers should act to protect swordfish this month (commentary)
- Between 1960 and 1996 swordfish declined more than 65%, the average size of fish caught shrank, and the species became severely overfished in the North Atlantic.
- A campaign led by consumer groups and chefs helped convince regulators like ICCAT to take action, to the point that the fishery is now considered ‘recovered.’
- Top chef and restaurateur Rick Moonen’s new op-ed argues that it’s time for a next step: “Now ICCAT has another opportunity to improve the long-term health of the swordfish population. This November, ICCAT members can adopt a new management approach for the stock and lock in sustainable fishing,” he says.
- This post is a commentary. 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.
To keep track of salmon migrations in real time, First Nations turn to AI
- Partnering with First Nations, a new interdisciplinary study proposes harnessing artificial intelligence and computer-based detection to count and produce real-time data about salmon numbers.
- Monitoring their population when they return to the rivers and creeks is crucial to keep tabs on the health of the population and sustainably manage the stock, but the current manual process is laborious, time-consuming and often error-prone.
- Fisheries experts say the use of real-time population data can help them make timely informed decisions about salmon management, prevent overfishing of stocks, and give a chance for the dwindling salmon to bounce back to healthy levels.
- First Nations say the automated monitoring tool also helps them assert their land rights and steward fisheries resources in their territories.
Not MPAs but OECMs: Can a new designation help conserve the ocean?
- To meet the landmark commitment struck last year to protect 30% of the ocean by 2030, the world’s nations will have to designate many new and large marine protected areas. But there’s also a different, less familiar option for meeting that target: “other effective area-based conservation measures,” or OECMs, areas that are not necessarily designed to protect biodiversity — they just happen to do so.
- Countries are now working to identify areas that meet the criteria and register them as OECMs, including in Africa where a recent webinar highlighted the promises and pitfalls of this relatively new conservation designation.
- Conservationists say OECMs could bring many positives, including the development, recognition or financing of de facto conservation areas led by local communities or Indigenous peoples.
- However, they also warn of the dangers of “bluewashing” or creating so-called paper OECMs that fail to deliver real conservation benefits in the rush to meet the 2030 deadline.
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.
Can blue bonds boost investment in ocean conservation? (commentary)
- Although they’re new vs. green bonds, the blue bond market is poised to take off as governments, companies, and investors begin to realize the importance of the blue economy and the relationship between climate change and the oceans.
- The Republic of Seychelles issued the first blue bond in 2018, with funds dedicated to expanding marine protected areas and improving fisheries governance. To date, only 25 other blue bonds have been issued.
- “The future of the blue bond market hinges on aligning financial incentives with environmental objectives, fostering innovation, and building a robust infrastructure that inspires trust and commitment from a diverse set of stakeholders,” a new op-ed states.

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.
Climate refugees? As the sea warms, corals thrive in Japan’s cool waters
- As tropical and subtropical coral reefs succumb to bleaching due to climate change in many parts of the world, the idea that they could take refuge in cooler, temperate seas has offered cause for hope.
- For a while, this is exactly what researchers thought was happening in Japan, where corals are replacing seaweed as the dominant benthos in many places, shaking up both ecosystems and coastal economies.
- But the latest research has tempered those hopes, showing that it’s mainly Japan’s genetically distinct temperate corals that have been expanding their range and edging out seaweed.
- The long-term implications of this shift are unclear, but researchers say it could take tens of thousands of years for these new high-latitude coral communities to evolve the structures, niches and symbioses necessary to support biodiversity on par with the world’s current tropical reefs.
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.
Oil firm Perenco eyes new blocks in DRC amid criticism of its track record
- Oil multinational Perenco has bid on two new oil blocks being auctioned off by the government of the Democratic Republic of Congo.
- Perenco operates the country’s only oil production facilities, at Muanda, near the mouth of the Congo River.
- Local and international critics accuse the oil company of polluting the environment, affecting fishing and farming, as well as residents’ health; the company denies this.
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.
South Africa’s penguins heading toward extinction; will no-fishing zones help?
- With just 10,000 breeding pairs left, the endangered African penguin (Spheniscus demersus) could be extinct in the wild by 2035 if the current rate of population decline continues.
- To protect the bird’s food supply and slow its population collapse, South Africa is throwing a protective no-fishing cordon around its main breeding colonies for a period of 10 years.
- But the devil is in the details, and conservationists say the cordons are too small to ensure the penguins get enough fish.
- Negotiations over whether to adjust the cordons are continuing in advance of an early 2024 deadline.
Fishing ban extension raises hopes for iconic Amazon pink river dolphin
- The Amazon river dolphin, or boto, is an integral feature of the rainforest’s biodiversity and culture, and is central to several Indigenous tales.
- Even though the dolphin isn’t fished for human consumption, it’s become endangered over the decades because fishers use its flesh as bait for catching piracatinga catfish.
- The Brazilian government earlier this year renewed a moratorium on fishing of piracatinga, first imposed in 2014, in the hope of saving the dolphin, but experts say fishers have just been ignoring the rule.
- The measure became even more relevant in October following the detection of more than 100 dead dolphins in an Amazon lake — experts suspect that the deaths are directly linked to the extreme drought affecting the region.
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.

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.
How the United Nations, kids and corporations saved the Red Sea from an oil disaster
- In August, an international effort led by the U.N. averted a massive oil spill in the Red Sea.
- The FSO Safer, a deteriorating oil tanker anchored in Yemen’s Marib Basin, posed a 1.14-million-barrel environmental and humanitarian threat, with a potential $20 billion cleanup cost.
- Even schoolchildren from Westbrook Elementary School in Maryland recognized the urgency and initiated their own fundraising efforts, but most oil companies with historical involvement in the Marib Basin have failed to contribute so far.
- While some nations and organizations stepped up to help, ongoing challenges in securing funding highlight the need for collective responsibility in preventing environmental disasters.
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.
As climate change hits the Turkish coast, more marine reserves are needed (commentary)
- The Mediterranean Sea’s marine life is facing many threats, not least of which is the rapidly rising water temperatures.
- The sea is warming faster than the global average, and with that warmth comes unwelcome tropical visitors like lionfish, which prey on native marine biodiversity, spurring conservationists to focus fishing pressure on these voracious predators, but that’s not all they’re doing.
- “We believe the expansion of the marine protected area network is now an essential next step, and we are working with the Turkish government to make this happen,” one such conservationist writes in a new op-ed.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
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.
Tien Hai Nature Reserve latest battleground in Vietnam’s push for development
- In April, the government of Vietnam’s Thai Binh province quietly issued a decision to remove protection from 90% of Tien Hai Nature Reserve, which forms an integral part of the UNESCO-recognized Red River Delta Biosphere Reserve.
- After environment activists publicized the decision last month, public backlash prompted officials to pause plans to develop a resort in the degazetted area — at least for now.
- The project is just one of several recent cases in which the country’s protected wetlands and forests have been threatened by development projects.
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.
For South Africa’s small fishers, co-ops prove a necessary, but bumpy, step up
- Sixteen years after small-scale fishers in South Africa were promised legal recognition and fishing rights, the policy regulating the new sector is at last being implemented.
- As fishing communities draw closer to finally claiming equal rights in a fishing industry that has been dominated by the commercial sector, they are currently forming cooperatives to access collective fishing rights and co-manage local marine resources.
- The rollout of the new policy has been long and bumpy, with many issues still to be resolved, and long-time fishers complaining they’ve been excluded.
- Even so, hope remains that cooperatives can hold new opportunities for income generation and equity building.
Hope, but no free pass, as Pacific corals show tolerance to warming oceans
- New research suggests that coral reefs in the Pacific islands of Palau are becoming increasingly tolerant to thermal stress brought on by climate change.
- The study found that Palau’s coral reefs appeared to suffer less bleaching over three successive marine heat waves in 1998, 2010 and 2017.
- While the findings provide some hope for coral reefs, one expert says the study has some limitations in providing a clear picture of how corals respond to different heat events.
- Scientists also say that reducing carbon emissions is essential to safeguard coral reefs — and to secure the planet’s future.
Off Mexico’s coast, world’s largest limpet is slipping into extinction
- Scutellastra mexicana, the world’s largest limpet, is at risk of extinction and requires urgent conservation action, according to a group of researchers.
- Once widely dispersed, the few remaining viable populations of these sea snails are now found in Mexico’s Islas Marias, a biosphere reserve. Though officially protected, the limpet continues to be harvested.
- Limpet species such as S. mexicana play an important role in maintaining coastal ecosystems, and research suggests they can mitigate some of the effects of warming oceans.
- Researchers are calling for “extreme protection” for S. mexicana and the Islas Marías to halt the species’ decline and potential extinction.
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.
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.
Offshore drilling faces backlash in Argentina after skirting environmental regulations
- Argentina granted permits to a dozen major oil companies to develop new offshore drilling projects near the Atlantic coast. But some of them may have disregarded policies meant to protect surrounding marine ecosystems.
- A court filing by the Environment and Natural Resources Foundation (FARN) argues that offshore drilling exploration could disorient, injure and even kill marine life and disrupt feeding and migratory areas.
- The companies that received permits include Equinor, Exxon Mobil, Qatar Petroleum Pluspetrol, Shell, Tullow, Total Austral and Shell, among others.
‘All will be well’: Q&A with Kenyan fisher turned coral gardener Katana Ngala
- Once a fisherman, Katana Ngala has been restoring corals near his home in Kuruwitu, Kenya, for more than 20 years.
- Early on, the area’s coral was degraded due to destructive fishing practices and coral bleaching, and he and other fishermen were experiencing diminished catches.
- Now the coral and fish are flourishing in the area, which the local community set aside as a no-fishing zone.
- Ngala spoke about the changes he’s seen in the coral garden over time and how he shares his commitment to the sea with fishers, students, scientists and the wider community in an interview with Mongabay at his seaside coral workshop.
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.
To protect the oceans, we must map them (commentary)
- About 80% of our oceans remain “unmapped, unobserved, and unexplored,” according to NOAA.
- Technologies like un-crewed marine drones, high-resolution satellites, and remote operating vehicles are now being paired with modern digital mapping techniques to reveal critical new insights about the oceans.
- “Considering we’ve barely mapped a quarter of [the oceans] so far, imagine what we could know, what we could prepare for, if every inch was mapped,” a new op-ed suggests.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Kenyan fishers put new twists on an age-old marine conservation system
- Over the past two decades Kenyan fishing communities have been setting up no-fishing zones called tengefus, Swahili for “set aside.”
- The idea was inspired by the fishing habits of their forebears, who prior to colonization established seasonal fishing closures to ensure plentiful harvests.
- Today there are 22 tengefus in various stages of development in the country, some more successful than others.
- Successful tengefus have seen fish populations and coral cover increase, and they’ve established tourism enterprises that fund community initiatives. To work, experts say tengefus need support from communities, donors and the government.
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.
Prickly babies: A Jamaican nursery aims to restore sea urchins felled by disease
- The long-spined sea urchin (Diadema antillarum) is a key algae grazer in the Caribbean. A disease outbreak in the 1980s killed off most of the urchins, resulting in the overgrowth of many Caribbean coral reefs with algae.
- Last year, a recurrence of the disease hampered the species’ slow recovery. This time, scientists were able to discover the culprit, which they revealed in a recent paper.
- The waters of Jamaica’s Oracabessa Bay Fish Sanctuary remained largely unaffected by the disease. Scientists there collected healthy long-spined sea urchins and started an urchin nursery in hopes of restoring the species on reefs around the island.
- This story was produced with support from the Pulitzer Center.
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.
Offshore oil plans in Brazil threaten South America’s largest coral reef
- The Parcel de Manuel Luís coral reef, off the coast of northeastern Brazil, is a vital habitat for several species, including 53 at risk of extinction.
- Despite vetoes from Brazil’s environmental regulator, the local government is seeking to give the go-ahead to oil drilling projects in this part of the Pará-Maranhão Basin.
- Oil drilling in the region also poses a threat to the longest continuous stretch of mangrove in the world, which runs from the Maranhão coastline to the northern state of Amapá, in the Amazon.
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.
Airport proposal for Malaysian island doesn’t fly with conservationists
- A proposal to build an international airport on Tioman Island in Malaysia would destroy coral reefs in the heart of one of the country’s most biodiverse marine parks and have wide-ranging impacts on local communities and biodiversity.
- Plans for the airport were rejected by authorities in 2018 due to the scale of the environmental impacts it would cause, but government officials are again considering an environmental impact assessment for the development.
- Many of the island’s 3,000 residents have been left in the dark about the plans, which could wipe out livelihoods in two of the island’s seven villages.
- Critics of the project recommend authorities focus on upgrading an existing airstrip on the island to accept larger aircraft and in the meantime invest in sustainable, meaningful, nature-based tourism.
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.
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.
S. Africa to purge bird-eating mice from key albatross breeding island
- Non-native house mice arrived on Marion Island in the southern Indian Ocean two centuries ago, when the island was a stopping-off point for sealing ships.
- Their population has exploded recently, as temperatures warm and summers lengthen. With more mouths to feed, they’ve gutted their main food source — insects — and are now feeding on seabird chicks and adults.
- While mouse attacks on seabirds remain low and their impact on nesting or breeding success isn’t known yet, conservationists nevertheless see them as a serious and growing threat.
- Now the South African government is planning a rodent eradication program for mid-2025 that will be the largest of its kind on a sub-Antarctic island.
Blue carbon deserves a green light for the climate fight (commentary)
- Marine habitats like mangrove forests, seagrass meadows, salt marshes, and kelp forests cover just 0.2% of the ocean surface and provide shelter & food for myriad life forms while containing 50% of the carbon sequestered in marine sediments.
- Yet at a time when the world needs to keep carbon sequestered to mitigate the effects of climate change, about 35% of the world’s mangroves and 30% of all seagrass meadows have been lost or degraded.
- A new op-ed argues that the world should be moving to reverse these trends: “We are currently throwing away a golden opportunity to tackle the climate crisis, bolster sustainable fisheries and allow wildlife to thrive.”
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
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.
The ‘Sloth Lady of Suriname’: Q&A with Monique Pool
- Monique Pool and the Green Heritage Fund Suriname (GHFS) have rescued and rehabilitated more than 600 sloths. The Xenarthra Shelter and Rehabilitation Center is a sanctuary for sloths and other Xenarthra species.
- Sloths in Suriname face threats from deforestation — including in and around the capital, Paramaribo — as well as urban expansion and development and attacks from people’s pets.
- Pool and the GHFS also raise awareness about dolphins and marine life, collaborating with veterinarians and scientists to study these species and preserve their habitats.
- The GHFS promotes sustainable development of natural resources and biodiversity in Suriname, providing information and education to create a better understanding of the country’s wildlife and ecosystems; Pool says she believes protecting and preserving sloths, dolphins and their habitats contributes to the overall health of the planet.
Tangled in marine debris, skate egg cases dry up and die on Peruvian beaches
- A new study has found that shorttail fanskate populations may be being affected by plastic pollution.
- The skates mistake abandoned fishing nets and other debris for seaweed and attach their eggs to them, unaware that the debris could wash up on the shore where the eggs will dry out.
- Shorttail fanskates (Sympterygia brevicaudata) are considered near threatened by the International Union for Conservation of Nature (IUCN).
Brazil claims record shark fin bust: Nearly 29 tons from 10,000 sharks seized
- Brazilian authorities announced the seizure of almost 29 tons of shark fins, exposing the extent of what they described as illegal fishing in the country. The previous record for the largest seizure reportedly took place in Hong Kong in 2020, when authorities confiscated 28 tons of fins.
- The seized fins, reportedly destined for illegal export to Asia, came from an estimated 10,000 blue (Prionace glauca) and anequim or shortfin mako (Isurus oxyrinchus) sharks, according to Brazil’s federal environmental agency IBAMA. Shortfin makos recently joined the country’s list of endangered species.
- IBAMA is filing infraction notices and fines against two companies over the seized fins. Other firms remain under investigation for illegal shark fishing related to the seizure, according to the agency.
- Through detailed analyses of the origins of these fins, an IBAMA statement said the agency identified a wide range of irregularities, including the use of fishing authorizations for other species and the use of fishing gear to target sharks.
New hope in the Mediterranean: Scientists find deep corals withstand heat waves
- Over the past decade, the Mediterranean Sea has experienced frequent, destructive marine heat waves that have impacted a diversity of marine life, including red gorgonians (Paramuricea clavata).
- In 2022, researchers launched “Noah’s Ark of the Deep,” an expedition to study the gorgonians in the western Mediterranean Basin. In April, the second mission of the expedition explored gorgonians below 50 meters (164 feet).
- While the gorgonians in shallow waters suffered as temperatures rose, corals in deeper waters appeared untouched by the impacts of thermal stress.
- Researchers are currently trying to understand if these deeper gorgonians can help repopulate shallow populations if climate conditions allow them to regenerate.
At sea as on land? Activists oppose industrial farming in U.S. waters
- Aquaculture produces more than half of the world’s seafood, mostly in inland and coastal waters. Industrial marine and coastal finfish aquaculture, such as salmon farming, accounts for just a fraction of that production, and comes with a host of negative environmental impacts.
- A set of agribusiness giants and other corporate interests are pushing to expand industrial finfish aquaculture into U.S. federal waters — the open seas — where proponents argue that it will help feed a growing global demand for seafood and have less environmental impact. They want Congress to pass legislation establishing a federal aquaculture system.
- Though Congress has not yet acted, in 2020, Donald Trump issued an executive order that gave the industry a boost, and government agencies have begun the permitting process for several projects in which finfish would be raised in open-ocean pens miles out to sea.
- Environmental advocates, including the campaign group Don’t Cage Our Oceans, are fighting against the proposed congressional bills, calling for a reversal of the executive order and a stop to the proposed projects in U.S. federal waters.
In Indonesia’s Aru Islands, a popular eco-defender climbs the political ladder
- A decade ago, Mika Ganobal campaigned to prevent Indonesia’s eastern Aru Islands from becoming a sugar plantation.
- Mika has since risen from a village chief to the head of one of the Aru Islands’ 10 subdistricts.
- Mika and his wife, Dina Somalay, are raising their children to understand and value a rich landscape that was almost lost a decade ago.
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.
Penguins ‘enrich our lives’: Q&A with Pablo Borboroglu, protector of penguins
- Pablo Garcia Borboroglu, a marine biologist from Patagonia, Argentina, was recently awarded the 2023 Indianapolis Prize for his work in protecting penguins around the world.
- Penguins face many threats, including pollution, human disturbance, and the impacts of fisheries and climate change.
- Borboroglu has helped protect penguins through various actions, including establishing marine and terrestrial protected areas, conservation research programs, and educational programs.
Several reef sharks at greater threat of extinction than thought, study shows
- A new study found that five key reef shark species — gray, blacktip, whitetip and Caribbean reef sharks, and nurse sharks — declined by 60-73% worldwide.
- It also indicated that all five species would qualify as endangered on the IUCN Red List.
- Early results from the study were used to escalate the status of two of the five species to endangered, but the others are still considered to have a lower extinction risk.
- The study also showed that well-governed or protected reefs had healthier shark populations.
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.
Can an app help Liberian artisanal fishers fight illegal fishing?
- Small-scale fishers in Liberia are using a data collection platform to document cases of illegal activity at sea.
- Artisanal fishers have long borne the brunt of illegal, unreported and unregulated (IUU) fishing, some of it occurring within an inshore exclusion zone that extends 6 nautical miles from shore.
- Through the use of a mobile app called DASE, released by the NGO Environmental Justice Foundation, local fishers can geotag images and videos of incidents at sea and submit them to the National Fisheries and Aquaculture Authority for verification and possible investigation.
- Though the app has not resulted in any prosecutions yet, fishers say it is having a deterrent effect on illegal activities.
New digital tool maps blue carbon ecosystems in high resolution
- The Blue Carbon Explorer, a digital tool developed by the nonprofit Nature Conservancy and the Earth-imaging company Planet, combines satellite imagery, drone footage and fieldwork to map mangroves and seagrass in the Caribbean, Papua New Guinea and Indonesia.
- The tool aims to help scientists, conservationists and governments gauge mangrove health and identify areas in need of restoration.
- The Blue Carbon Explorer comes at a time of growing interest in blue carbon ecosystems as potential nature-based solutions for climate change.
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.
Illegal fishing for fish meal widespread in Ecuador marine reserve
- Industrial fishing is prohibited in the coastal waters of the Cantagallo-Machalilla Marine Reserve in Ecuador’s Manabí province, which is home to numerous threatened species.
- Yet between November 2020 and March 2022, more than half of the government alerts for unauthorized fishing in Manabí province occurred within the marine reserve, according to a Mongabay analysis.
- Local residents say industrial ships enter the reserve’s waters to illegally harvest small pelagic fish like anchovies and sardines for processing into fish meal, despite a government order prohibiting this practice. They say the fish are dwindling, reducing food for people and wildlife alike.
- Created in 2015, the marine reserve’s management plan is still considered a draft, leaving the reserve without the management mechanisms needed to control the illegal fishing.

New index identifies marine reserves that are protected in theory only
- Marine protected area (MPA) status doesn’t guarantee that conservation efforts are effective, according to new research that looks at the de facto situation of preserved areas around the world.
- A third of the MPAs analyzed appear likely to be protected only on paper, most of them in Latin America, Southeast Asia and Oceania, and the Indian Ocean.
- Researchers created a Paper Park Index (PPI) based on interviews with local stakeholders and their perceptions of fishing levels within MPAs, with the PPI showing the difference between the theoretical goals of the MPAs and the reality on the water.
- The new methodology could help provide more realistic information about the effectiveness of MPAs and support further conservation efforts, the study suggests.
U.S. says Mexico failed to uphold international treaty protecting vaquita porpoise
- The United States said the government of Mexico has failed to stem the illegal harvest and commercial export of totoaba, which has directly impacted the vaquita.
- The vaquita has dwindled to around just 10 specimens in recent years, the result of getting caught in gillnets targeting totoaba, whose swim bladder is treasured on the Chinese black market.
- US law allows for an embargo on wildlife trade when a country isn’t doing enough to combat illegal activity. However, it isn’t clear that President Joe Biden will take that step.
As one Indian Ocean tuna stock faces collapse, nations scramble to save others
- Indian Ocean Tuna Commission members failed to make progress on key measures to protect declining yellowfin tuna (Thunnus albacares), like reducing annual catches and limiting the use of harmful fish aggregating devices (FADs), during their annual meeting.
- Although the commission declared yellowfin tuna overfished in 2015, to date, the intergovernmental regional management body has failed to curb overfishing, bringing the stock closer to collapse.
- Objections from the European Union helped nullify an ambitious plan adopted by the IOTC in February to limit the use of drifting FADs: Objecting parties don’t have to implement the measure, and the EU tuna fleet, which has historically pulled in the largest yellowfin tuna catches in the Indian Ocean, is the biggest deployer of DFADs in the region.
- The commission declared the Indian Ocean bigeye tuna (T. obesus) stock overfished in 2022, and at its meeting in May parties agreed to a 15% reduction from 2021 levels in the permitted annual catch; they also adopted protective measures for seabirds and marine mammals at the meeting, but not for sharks.
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.
Record year for olive ridley turtles in Bangladesh as conservation work pays off
- Bangladesh has recorded the highest number of olive ridley turtle eggs this nesting season, a conservationist group says.
- The species’ main nesting grounds in Bangladesh are the various small islands off the southeastern district of Cox’s Bazar in the Bay of Bengal.
- Extensive conservation action across the area and the awareness programs carried out among local communities are the key reasons behind the success.
- However, the growth of the tourism industry and infrastructure development continue to pose major threats to the turtles and their nesting grounds.
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.
Targeting 3% of protected areas could accelerate progress on 30×30 goals, says Global Conservation’s Jeff Morgan
- In December, world leaders adopted the Kunming-Montreal Global Biodiversity Framework, targeting the conservation of 30% of Earth by 2030.
- However, Jeff Morgan, founder of Global Conservation, points out that simply designating protected areas is not enough to safeguard nature. His organization, therefore, focuses on strengthening protection within UNESCO World Heritage Sites in lower and middle-income countries, utilizing cost-effective technologies for law enforcement against poaching, illegal logging, and more.
- Global Conservation currently operates across 22 national parks and 10 marine parks in 14 countries and aims to expand its work to 100 sites by 2033. Morgan believes that this focus on existing national parks and habitats is the most efficient and cost-effective way to achieve climate goals.
- Morgan recently spoke with Mongabay founder Rhett A. Butler about Global Conservation’s approach.
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.
Spamming streams with hatchery salmon can disrupt ecosystems, study finds
- In a new study, researchers found that releasing hatchery-bred native masu salmon into freshwater streams in Hokkaido, Japan, destabilized the local ecosystems.
- Overall, the study found that the total number of fish, and number of different species, both declined in the long term due to greater competition for resources like food and preferred feeding spots.
- Masu salmon populations also did not increase in the long term, the research found.
- With hatchery releases increasing in many areas — and for many species — the findings add to the ongoing debate over their wider effects on wild fish populations.
The Mexican family who gave up fishing to monitor and rescue sea turtles
- The Kino Bay Turtle Group is made up of a family of former fishers from the state of Sonora in northwestern Mexico.
- The group keeps a close watch on sea turtles in the La Cruz Lagoon, a Ramsar site spanning 6,665 hectares (about 16,470 acres), monitoring the animals, rescuing any that become entangled and educating the public about their importance.
- The group has captured and logged data on more than 800 sea turtles; it is now training a team of Indigenous Comcáac youth to form their own turtle group and begin monitoring and conservation work along a 10-kilometer (6-mile) stretch of coast in Sonora.
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.
A Philippine town and its leaders show how mangrove restoration can succeed
- In the early 1990s, the coastal town of Prieto Diaz, in the Philippines’ Bicol region, was selected as a pilot area for a community-based resource management program created by the Department of Environment and Natural Resources.
- Today, an award-winning community organization helps maintain a mangrove ecosystem that has grown to be the region’s largest and supports the livelihoods of both its members and the broader community.
- Residents credit the restored mangrove ecosystem with protecting the village from storm surges, and point to committed local leaders as vital to the ongoing success of mangrove restoration and protection.
Global Ocean Census aims to find 100,000 marine species in 10 years
- A new initiative called the Ocean Census aims to expand marine biodiversity knowledge by finding 100,000 new marine species within a decade.
- It will send scientists on dozens of expeditions at marine biodiversity hotspots and use advanced technology like high-resolution imagery, DNA sequencing and machine learning, to identify new species.
- Scientists estimate that only about 10% of marine species have been formally described, and about 2 million species have yet to be identified.
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.
Colombia: Scientists explore remote seamounts to protect hammerhead sharks
- Since 2000, the Malpelo and Other Marine Ecosystems Foundation has conducted 40 expeditions on and around Malpelo Island, a rocky outpost about 500 kilometers (310 miles) off Colombia’s Pacific coast.
- These expeditions have allowed the foundation to gather information about the area’s population of scalloped hammerhead sharks (Sphyrna lewini) and to discover this critically endangered species’ breeding areas.
- They’ve also influenced the expansion of the Malpelo Fauna and Flora Sanctuary and UNESCO’s declaration of it as a World Heritage Site.
- Malpelo Foundation researchers hope their new expeditions to the area’s seamounts, which form a vital corridor for migratory species, will inform the ongoing fight against illegal fishing that threatens the hammerheads and other marine fauna.
Mouth of the Amazon oil exploration clashes with Lula’s climate promises
- State-owned Petrobras has requested a license to investigate an oil site in a region in the north of Brazil where the Amazon River meets the Atlantic Ocean.
- The region is home to swathes of mangroves and coral reefs that environmentalists say are highly biodiverse and fundamental to local communities.
- Experts demand that Brazil’s environmental agency reject the license, saying the government hasn’t conducted the required detailed studies to assess the potential impact.
- Critics warn that pursuing fossil fuels contradicts President Luiz Inácio Lula da Silva’s vows to adopt a renewable energy strategy and clashes with global climate change guidelines.
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.
Parasites of the Caribbean: Study pinpoints cause of sea urchin die-off
- Once abundant in the Caribbean, long-spined sea urchins (Diadema antillarum) experienced a mass die-off in the early 1980s, contributing to coral reef deterioration.
- Another die-off occurred in 2022, leading to a further decline in coral reef health in some parts of the Caribbean.
- A new study has identified the culprit: a parasite called a ciliate that took over the sea urchins’ bodies and quickly killed them.
- While researchers are still trying to determine how this disease is transmitted, they say it’s possible that climate change played a role.
Home to rare corals, a Chilean fjord declines in spite of protection
- The Comau Fjord, in the Chilean region of Patagonia, is one of the only sites in the world where the cold-water coral Desmophyllum dianthus lives just 5 meters (16 feet) below the sea surface.
- The easy access to these animals, which elsewhere live at extreme depths, motivated a group of scientists to study them.
- Their research brought new information to light about the corals’ biology and also revealed that the Comau Fjord is at serious risk.
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.
What’s black and white and spins? Wind turbines that don’t kill birds
- A new study suggests a way to stop seabirds from colliding with wind turbines: painting a black-and-white pattern on all three blades and the pylon to produce a flickering effect.
- This strategy has yet to be tested or implemented, but experts believe it has promise and would create its desired effect.
- However, getting approval for painting wind turbines can be difficult, and this mitigation strategy might generate the unintended effect of displacing seabirds, one expert says.
- It’s estimated that wind turbines kill thousands of birds in the U.K. alone.
‘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.
New MPA Tic-Toc Golfo Corcovado a safe haven for blue whales in Chile
- Chile declared some 100,000 hectares (247,100 acres) in the Gulf of Corcovado in Northern Patagonia a marine protected area, the highest category of protection.
- The area is an important feeding and breeding ground for endangered blue whales as well as home to numerous other marine mammal species.
- However, it represents only a small fraction of the blue whales’ range, so scientists say additional conservation efforts must continue.
In Chile’s Patagonia, another salmon plant angers water defenders
- The Dumestre salmon plant near the Chilean city of Puerto Natales is receiving backlash from conservationists who say the facility will dump waste into Patagonian waters.
- The plant can process over 70,000 tons of fish per year, requiring the management of 23,000 cubic meters of industrial liquid waste and the movement of 350 ships in the Señoret canal.
- Local activists say the community wasn’t properly consulted about their needs before the plant was opened.
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.
Indigenous Comcaac serve up an oceanic grain to preserve seagrass meadows
- The Indigenous Comcaac community of northwestern Mexico is working to preserve eelgrass and promote the renaissance of the grain they obtain from it.
- Known as xnois, this grain from the Zostera marina seagrass was once a vital ingredient in Comcaac food, and was sustainably harvested without harming seagrass meadows.
- Current generations of Comcaac hope to revive the ancient traditions while preserving the seagrass meadows off the coast of their territory.
- Through a recent cultural festival, they showcase the versatility of xnois in both traditional and modern cuisine, from tortillas to energy bars.
Fishing industry transparency is key for a thriving ocean (commentary)
- As fish populations decline in many regions, unscrupulous fishing fleet operators have turned to illegal fishing, human trafficking, slavery and other abuses to cut costs.
- This is facilitated by the complex, opaque nature of global fisheries, but there is one essential step every government can and must take to end this and bring fisheries out of the shadows: introducing comprehensive transparency.
- “The fact that illegal fishing, human rights abuses and ecological collapse in the ocean are so closely interlinked means that systematic, rigorous transparency can help to resolve them all,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
As livelihoods clash with development, Vietnam’s Cần Giờ mangroves are at risk
- Cần Giờ, a coastal district of Ho Chi Minh City, is home to a 75,740-hectare (187,158-acre) mangrove forest, planted and maintained as part of post-war reforestation efforts.
- The district’s residents largely depend on aquaculture, shellfish gathering and small-scale ecotourism for their livelihoods.
- The government and developers hope to market the area as an ecotourism city based on its natural beauty and post-war success story, but major projects could disrupt Cần Giờ’s precarious balance between ecosystems and livelihoods.
- All names of sources in Cần Giờ have been changed so people could speak freely without fearing repercussions from authorities.
‘Locals want their resources to last’: Q&A with marine ecologist Vilma Machava-António
- Ocean Revolution Mozambique (ORM), a recipient of the UNDP’s Equator Prize for 2022, promotes marine conservation in the East African nation by supporting Mozambican researchers in their quest for knowledge.
- “You cannot talk about ecosystem conservation without talking about people,” says Vilma Machava-António, a researcher who benefited from an ORM scholarship.
- The marine ecologist spoke to Mongabay about what attracted her to mangroves, the role these unique coastal systems play in climate adaptation, and what explains the success of some community-led efforts to preserve them.
- Mangroves stash carbon efficiently and are critical to adapting to climate impacts, especially in Mozambique, which is hit by cyclones with distressing frequency.
Machine learning makes long-term, expansive reef monitoring possible
- Conservationists can now monitor climate impacts to expansive marine ecosystems over extended periods of time, a task that used to be impossible, using a tool developed by scientists in the U.S.
- The machine learning tool, called Delta Maps, provides a new way to assess which reefs might be best suited for survival, and which play a key role in delivering larvae to others, and therefore should be targeted for preservation efforts, according to the scientists.
- The scientists used the tool to examine the impacts of climate change on connectivity and biodiversity in the Pacific Ocean’s Coral Triangle, the planet’s most diverse and biologically complex marine ecosystem.
- The authors also noted that the Coral Triangle had more opportunities for rebuilding biodiversity, thanks to the region’s dynamic climate component, than anywhere else on the planet.
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.
U.S. grocery chains flunk sustainability, human rights tests for tuna sourcing
- Greenpeace has scored the 16 largest U.S. grocery retailers on human rights and environmental sustainability in their tuna sourcing, giving just one, ALDI, a “passing” overall grade.
- The report gave just two of the retailers, ALDI and Whole Foods Market, passing grades for addressing sustainability issues.
- None of the retailers received a passing grade for efforts to rid their supply chains of forced labor and other human rights abuses.
- The U.S. is the world’s second-largest tuna importer and its retailers wield significant clout within the tuna sector, according to the report.
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.
Failed mangrove tourism project in Sumatra highlights need for community collaboration
- Once a bustling attraction, the Sicanang Mangrove Forest ecotourism project in North Sumatra is padlocked and falling into disrepair.
- Launched in 2019, the project was supported by Sumatra-based NGO Yagasu but fell apart in the wake of claims that the project was improperly established on private land.
- Facing multiple accusations, Yagasu withdrew from the project, which failed without the organization’s support. The outcome, Yagasu staff say, highlights the importance of close collaboration among NGOs, local governments and community groups.
Recent seismic activity in Indian Ocean likely led pilot whales to beach on Sri Lanka shores
- Marine experts say the seismic activity in the Indian Ocean in the past few days likely pushed a pod of pilot whales onto Sri Lanka’s shores.
- Authorities and volunteers undertook a strenuous 15-and-a-half-hour operation to send a pod of pilot whales safely back into the sea.
- Rescuers managed to push 11 pilot whales back into the sea while three died on the shores.
- Recorded incidents of whales beaching up on Sri Lankan shores go back as far as 1889.
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.
Costa Rica announces ban on fishing of hammerhead sharks
- Costa Rica announced an all-out ban on the fishing of hammerhead sharks, specifically the smooth hammerhead (Sphyrna zygaena), scalloped hammerhead (Sphyrna lewini) and great hammerhead (Sphyrna mokarran).
- Despite being critically endangered, hammerhead sharks have been bought and sold in Costa Rica for years, with demand being driven by shark fin soup.
- Although some conservation efforts have been made in the past, the government has been heavily criticized up to now for its relaxed approach to dealing with the overfishing of hammerheads.
Win for science as BP pressured into cleaning up offshore gas plans
- BP is launching an offshore gas platform with a pipeline through the world’s largest cold deep-water coral reef off the coast of Senegal and Mauritania.
- The project’s environmental impact assessment has been described as “nonsense” by a group of marine biologists
- A group of scientists has been fighting for four years to change this. Their proposals are currently being studied.
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.
Chile’s denial of Dominga port project is a just energy transition victory and lesson (commentary)
- Last week, Chile rejected the Dominga copper and iron mining project and its port, proposed for a location near the Humboldt Penguin National Reserve.
- Dominga’s estimated 20 to 30 years of operation would have jeopardized a marine biodiversity hotspot, along with human livelihoods and communities’ access to basic resources.
- “Dominga’s rejection is a victory for environmental justice and a lesson about the underlying tensions in the energy transition,” writes the author of a new op-ed.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
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.
