To renew or not to renew? African nations reconsider EU fishing deals
- The European Union currently has fisheries access deals with 11 African countries, several of which are up for renegotiation this year.
- Under the deals, called Sustainable Fisheries Partnership Agreements (SFPAs), European fishing companies gain access to resource-filled foreign waters, while the African countries get cash.
- Senegal was the first country to sign such a deal, in 1979, but President Bassirou Diomaye Faye was elected in March after proposing to suspend it altogether in response to concerns that it’s unfair to local fishers. It’s not yet clear whether he will follow through, but his rhetoric reflects shifting arrangements in African fisheries, where the EU no longer dominates as it once did.
- Experts see this as a possible win for local control of precious marine resources, but they also caution that many of the alternative arrangements African governments are turning to instead of SFPAs are more socially and environmentally problematic, and less transparent.
Twilight zone fishing: Can we fish the ocean’s mesopelagic layer?
- Fishing experts are looking for ways to fish in the mesopelagic zone, a layer of water that stretches from 200-1,000 meters (660-3,300 feet) beneath the surface, which has, thus far, remained relatively unexploited.
- Many challenges stand in the way of making mesopelagic fishing a reality, such as the difficulties of finding and capturing mesopelagic fish, and processing them into usable products.
- Yet experts are working to overcome these obstacles, with one suggesting that mesopelagic fishing could begin in the next few years.
- Conservation experts have expressed concern about the possible start of mesopelagic fishing, arguing that it could cause environmental problems.
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.
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.
One of Colombia’s largest estuary ecosystems is drying up, communities warn
- Decades of sediment pollution, contamination and government infrastructure projects have disrupted the natural flow of saltwater and freshwater into the Ciénaga Grande of Santa Marta, one of Colombia’s key wetlands and a major estuary on the Caribbean Sea.
- Fish stocks have also plummeted, with profitable, big species being replaced by smaller ones and leaving fishing communities without their livelihoods.
- Although authorities claim that they are investing in the region, locals complain the autonomous corporation in charge is not taking steps to dredge the canals and that there isn’t enough transparency on how the money is being spent.
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.
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.
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.
Stalemate: WTO talks again fail to end overfishing subsidies
- At the World Trade Organization’s 13th ministerial conference (MC13), which closed in Abu Dhabi on March 2, negotiators failed to finalize phase two of an international treaty banning harmful fisheries subsidies.
- Despite 22 years of negotiations, member states remained divided on crucial aspects of the treaty to phase out subsidies worth an estimated $22 billion annually that support overfishing.
- The draft negotiating text includes contentious loopholes, raising concerns about fairness and effectiveness from state delegates, fisheries experts and scientists.
- Ratifications of phase one of the treaty leapt to 71 as 10 more states signed up during MC13, but 39 more are needed for implementation.
Norwegian salmon farms gobble up fish that could feed millions in Africa: Report
- Norwegian salmon farms are taking huge amounts of wild fish from West Africa, mining the food security of the region, according to a report from the U.K.-based NGO Feedback.
- In 2020, the industry produced salmon feed ingredients using up to 144,000 metric tons of small pelagic fish caught along the coasts of West Africa, where they could have fed between 2.5 million and 4 million people, according to the report.
- The analysis comes as the industry faces a wave of public opposition after revelations of high mortality rates and the sale of fish deemed unfit for human consumption, along with accusations of antitrust violations by the European Commission.
Hong Kong as a reef fish haven? These scientists want to get the word out
- For the past 10 years, marine biologist and conservationist Stan Shea has been leading a citizen-science program called the 114°E Hong Kong Reef Fish Survey to compile data on local reef fish species and raise awareness about the marine environment.
- The program relies on a core network of around 50 volunteer divers, who assist Shea with his mission to raise awareness about Hong Kong’s aquatic life.
- There are likely about 500 reef fish species in Hong Kong, but only about 460 have been identified so far; Shea and his team aim to find and document as many of the other overlooked as possible.
- Shea is also working on a photographic book about Hong Kong’s reef fish, which will be published in 2026.
With drop in illegal fishing comes rise in piracy, study in Indonesia finds
- Indonesia’s crackdown on illegal fishing is driving an increase in maritime piracy, a new study shows.
- In recent years, the government has taken harsh measures against illegal fishers, including banning foreign fishing vessels from its waters, and blowing up those it seizes.
- However, researchers say the crackdown’s success, without addressing the drivers of illegal fishing, including poverty, “can inadvertently shift effort from fishing to piracy.”
- Illegal fishing costs an estimated $3 billion in lost revenue for Indonesia, the world’s second-biggest producer of wild-caught seafood.
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.
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.
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.
Kenyan villagers show how to harvest more octopus by fishing less
- Residents of Munje, a fishing village south of the Kenyan port of Mombasa, have established an octopus closure to ensure sustainable fishing.
- Octopus catches in the reefs just offshore had been declining as larger numbers of fishers, often using damaging techniques, hunted this profitable species.
- Previous attempts to regulate the octopus fishery had failed, but the village’s beach management unit enlisted support from an NGO to replicate successful strategies from elsewhere.
- Clearer communication and patient consensus-building have secured buy-in from the community, and the village is anticipating a second successful harvest period in February.
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.
Spain sanctions fishing vessels for illegally ‘going dark’ near Argentine waters
- The Spanish government sanctioned 25 of its vessels for illegally turning off their satellite tracking devices while fishing off the coast of Argentina between 2018 and 2021.
- Experts say ships that “go dark” by turning off their trackers often do so to partake in illicit behavior, such as crossing into a nation’s exclusive economic zone (EEZ) without authorization.
- While some have praised the Spanish government’s actions, one expert says he doesn’t believe the sanctions go far enough.
- Most fishing activity in this region is also unregulated and unmonitored, which raises environmental concerns.
Salmon and other migratory fish play crucial role in delivering nutrients
- Pacific salmon can play a key role in transporting nutrients from marine to freshwater and terrestrial ecosystems.
- In the past, Pacific salmon and other anadromous fish that spawn in freshwater and spend part of their life in the ocean likely played a much larger role in global nutrient cycles, scientists find.
- But today, many populations of Pacific salmon and other anadromous fish are under pressure from habitat loss, overfishing, climate change, dams and other pressures that have greatly reduced their numbers, weight and ability to migrate freely.
- Population declines could further curtail their role in global nutrient transport in future, with increasing consequences, especially for nutrient-poor ecosystems that have relied in the past on migratory fish for significant nutrient additions.
Still on the menu: Shark fin trade in U.S. persists despite ban
- An Al Jazeera investigative report has revealed that the trade in shark fins is still happening in the U.S. despite legislation banning the activity.
- The report also showed illegal shark finning operations occurring in Peru, currently the world’s largest exporter of fins due to laws that make this export legal, and in Ecuador, where sharks are landed in high volumes.
- A year ago, the international convention on wildlife trafficking enacted shark trade bans, but this has not yet stamped out the global fin trade, prompting experts to call for better enforcement and scrutiny.
Farewell, Java stingaree: Scientist declare the first marine fish extinction
- In December 2023, scientists declared the Java stingaree (Urolophus javanicus), a species of stingray, extinct.
- It’s the first marine fish confirmed to have gone extinct due to human actions.
- Scientists know very little about the species, which they haven’t spotted since a naturalist purchased the specimen from which he described the species at a fish market in Jakarta in 1862.
‘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.
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.
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.
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.
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.
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.
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.
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.
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.
Sumatran Indigenous seafarers run aground by overfishing and mangrove loss
- Many among Indonesia’s Duano Indigenous community have hung up their fishing nets in response to recent environmental and economic shifts.
- A study published in October found that intact mangroves were associated with up to a 28% increase in fish and shellfish consumption among coastal communities.
- Duano elders say young people from the community are increasingly retiring from the community’s traditional livelihood to take up poorly paid casual work.
Record North Atlantic heat sees phytoplankton decline, fish shift to Arctic
- Scientists warn that record-high sea surface temperatures in the North Atlantic Ocean this year are having consequences for sea life.
- As marine heat waves there have worsened over the years, populations of phytoplankton, the base of the oceanic food chain, have declined in the Eastern North Atlantic.
- With experts predicting more heat anomalies to come, North Atlantic fish species are moving northward into the Arctic Ocean in search of cooler waters, creating competition risks with Arctic endemic species and possibly destabilizing the entire marine food web in the region.
- Lengthening and intensifying marine heat waves around the globe are becoming a major concern for scientists, who warn that the world will see even greater disruptions to ocean food chains and vital fisheries, unless fossil fuel burning is curtailed.
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.
Indonesian village forms coast guard to protect octopus in Mentawai Islands
- An island community in Indonesia’s Mentawai archipelago has responded to dwindling octopus stocks with a seasonal fishing closure to enable recovery.
- Global demand for octopus is expected to outpace supply over the medium term, implying higher dockside prices for many artisanal fishers, if stocks can be managed sustainably.
- Maintenance of local fishing grounds also offers crucial nutritional benefits for remote coastal communities in the Mentawais, where rates of child stunting exceed Indonesia’s national average.
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.
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.
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.
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.
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.
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.
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.
West African fishers strike for fair wages and ‘respect’ on EU-owned vessels
- African fishers, mostly from Senegal and Ivory Coast who work on dozens of EU vessels that operate in West Africa and the Indian Ocean, took part in a strike that lasted from June 5-8, alleging wage violations.
- Vessels owned by EU companies are allowed to fish in foreign countries’ waters through agreements between the EU and the host nations. However, a third of such vessels operating in West Africa use flags of other countries and evade labor rights provisions agreed to under these pacts.
- Fishers who participated in the strike told Mongabay they were fighting for more than fair wages, saying that African sailors were not treated with respect on European boats despite doing some of the most arduous jobs.
- Seafarers’ unions called off the strike after the Senegalese government initiated negotiations with vessel owners and unions. Talks are expected to conclude in five months.
Can Spain keep the rising sea from washing away a critical delta?
- One of Europe’s most important deltas, a vital wildlife sanctuary and economic engine, is facing a myriad of threats stemming from climate change and water management.
- Rising sea levels and stronger storms are washing away the very sediment that constitutes the Ebro Delta and sending saltwater far inland.
- The government plan to bolster the delta relies heavily on trucking sediment to its exposed outer banks, but it’s a stop-gap measure until researchers can develop a more sustainable long-term solution.
- The question is: Can they find one in time?
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.
Indonesia looks into tuna farming to boost aquaculture, reduce overfishing
- Indonesia is developing tuna farming in the country’s bays in an effort to boost its aquaculture sector and ease the pressure on its world-leading marine tuna fishery.
- The fisheries ministry said it was consulting with international fisheries experts about implementing tuna farming.
- Indonesia’s archipelagic waters are key fishing grounds for several many tuna species, as well as spawning grounds for the fish.
- Indonesia’s tuna fisheries is an important source of livelihood for coastal communities and a key source of food for consumers around the world.
Europe’s top science panel supports call for moratorium on deep-sea mining
- The European Academies’ Science Advisory Council has announced its support for a moratorium on deep-sea mining.
- In a new report, the council conveys its skepticism that deep-sea mining is necessary to meet the needs of critical minerals for renewable technologies.
- It also points out that deep-sea mining would cause irreparable harm to marine ecosystems, and that the mining regulator lacks a scientific definition of what qualifies as serious harm.
- Many European nations and companies currently possess licenses to explore the international seabed for resources, although exploitation has yet to begin.
A Southeast Asian marine biodiversity hotspot is also a wildlife trafficking hotbed
- A recent report documents the seizure of 25,000 live animals and more than 120,000 metric tons of wildlife, parts and plants from the Sulu and Celebes seas between 2003 and 2021.
- The animals trafficked include rays, sharks and turtles, mostly between Indonesia, the Philippines and Malaysia, for which the region forms a maritime border zone.
- The people of the Sulu and Celebes seas region have strong transboundary cultural and trade links, prompting experts to call for enhanced international cooperation in enforcement efforts.
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.
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.
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.
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.
Saving forests to protect coastal ecosystems: Japan sets historic example
- For hundreds of years, the island nation of Japan has seen various examples of efforts to conserve its coastal ecosystems, vital to its fisheries.
- An 1897 law created protection forests to conserve a variety of ecosystem services. “Fish forests,” one type of protection forest, conserve watershed woodlands and offer benefits to coastal fisheries, including shade, soil erosion reduction, and the provision of nutrients.
- Beginning in the late 1980s, fishers across Japan started planting trees in coastal watersheds that feed into their fishing grounds, helping launch the nation’s environmental movement. Although the fishers felt from experience that healthy forests contribute to healthy seas, science for many years offered little evidence.
- New research using environmental DNA metabarcoding analysis confirms that greater forest cover in Japan’s watersheds contributes to a greater number of vulnerable coastal fish species. Lessons learned via Japan’s protection and fish forests could benefit nations the world over as the environmental crisis deepens.
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.
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.
‘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.
Fishy business of squid vessels needs stronger regulation, study says
- Experts are drawing attention to the unregulated nature of squid fishing, which they say could lead to the overexploitation of species, allow illegal fishing activity to flourish, and contribute to inequity.
- New research suggests that squid fishing increased by 68% across the global oceans between 2017 and 2020, and that 86% took place in unregulated parts of the ocean.
- China’s distant-water fishing fleet accounts for 92% of this tracked squid fishing activity.
- Experts say that unregulated squid fishing needs to be addressed with better management, monitoring and transparency.
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.
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.
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.
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.
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.
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.
More marine protected areas planned for Indonesia’s Maluku after 2022 spree
- The Maluku Islands in Indonesia will protect more swaths of their seas this year, following from the designation of five marine protected areas in 2022 alone.
- The new protected areas will cover the waters around the western island of Buru, where fishing activity will be limited to traditional fishers using sustainable gear.
- Indonesia currently has 284,000 square kilometers (110,000 square miles) of marine area under protection, roughly two-thirds of its target of protecting 10% of its waters.
- The Maluku Islands sit within the Pacific Coral Triangle, an area renowned for its richness of corals and reef fish.
Fishers on Indonesia’s Batam Island suffer as mangrove cover declines
- Fishing is becoming a meager profession in Indonesia’s industrial and resort hub of Batam.
- Satellite imagery shows that only 1.5% of the island’s landmass still retains mangrove habitat.
- Construction of dams, industrial estates and reservoirs are the primary causes of mangrove destruction, according to researchers and local environmental nonprofit Akar Bhumi.
Sharks received landmark protection to combat fin trade, but the culling must stop (commentary)
- CITES CoP19 marked a historic win for shark conservation and the fight against the global trade in shark fins and meat, but an equally critical issue that must be tackled is shark culling.
- For many decades, popular culture and media, through the choice of words and visual depictions, have portrayed sharks as a threat to humans. Several countries actively kill sharks in mass numbers to control their presence near beaches.
- While shark nets and drumlines can separate the sharks from the humans at beaches, they aren’t fully effective. There are new methods that use technology, like electric shark repellents and magnetic and visual stimuli, work better to prevent human-shark encounters.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
2022’s top ocean news stories (commentary)
- Marine scientists from the University of California, Santa Barbara, share their list of the top 10 ocean news stories from 2022.
- Hopeful developments this past year include the launch of negotiations on the world’s first legally binding international treaty to curb plastic pollution, a multilateral agreement to ban harmful fisheries subsidies and a massive expansion of global shark protections.
- At the same time, the climate crises in the ocean continued to worsen, with a number of record-breaking marine heat waves and an accelerated thinning of ice sheets that could severely exacerbate sea level rise, underscoring the need for urgent ocean-climate actions.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Mongabay Explains: What’s all the brouhaha over bottom trawling?
- A new episode of “Mongabay Explains” examines the controversial fishing method known as bottom trawling, in which vessels drag a net across the seafloor to scoop up bottom-dwelling marine life.
- Ever since the 14th century, fishers who use other gear types — later joined by conservationists and scientists — have objected to bottom trawling, saying the gear takes too many fish and destroys seafloor habitat that’s essential to the functioning of marine ecosystems.
- Proponents of bottom trawling, however, argue that the practice provides an important share of our seafood as well as numerous jobs, and cannot be abandoned.
- In this video, Mongabay takes a look at bottom trawling and the reasons it’s so controversial.
Strong marine protected areas credited with manta ray surge in Indonesia
- Manta ray populations are thriving in Indonesia’s Raja Ampat archipelago, a new population assessment shows, highlighting the importance of marine protected areas to the species’ conservation.
- The study showed that reef manta ray (Mobula alfredi) populations saw up to 10.7% compound annual increase from 2009-2019 in the region, even as global ray and shark populations undergo a sweeping decline.
- The study authors attribute this to well-planned and -implemented conservation measures by Indonesian authorities, conservation groups and local communities.
- The finding chimes with the discovery earlier this year that manta ray populations are also flourishing in Komodo National Park, another tightly regulated protected area in Indonesia.
From bombs to seasonal closure, Indonesian fishers move toward sustainability
- Kahu-Kahu village on Sulawesi’s Selayar Island is implementing its first season- and location-based fishery closure.
- The three-month closure of a 6-hectare (15-acre) stretch of coastal water is intended to replenish local octopus populations by reducing fishing pressure.
- Local fishers will install and plant artificial reefs in the area during the closure.
Dalian Ocean Fishing, subject of Mongabay probe, now sanctioned by U.S.
- The U.S. Department of the Treasury’s Office of Foreign Assets Control recently announced sanctions on Chinese individuals and companies allegedly involved in human rights abuses and illegal, unreported, and unregulated (IUU) fishing while operating in distant waters.
- One sanctioned company, Dalian Ocean Fishing Co., Ltd. (DOF), was the subject of two Mongabay investigations: one uncovered widespread human rights abuses, and the other exposed extensive illegal shark-finning operations within the DOF fleet of longline fishing vessels.
- China, which operates the world’s largest distant-water fishing fleet and has a long history of fisheries offenses, denounced the sanctions, saying that it is a “responsible fishing country.”
Shark-fishing gear banned across much of Pacific in conservation ‘win’
- The Western and Central Pacific Fisheries Commission has outlawed shark lines and wire leaders, both of which aid industrial-scale fishers in targeting sharks.
- Shark numbers in the open ocean have dropped by roughly 71% in the past 50 years.
- Proponents consider the measure a potentially precedent-setting move that could precede similar bans in other regions.
Fishers in Flores Sea opt to limit harvest of overexploited sea cucumbers
- Fishers on Indonesia’s Sapuka island have decided to regulate their sea cucumber harvests.
- Since the 1960s, sea cucumber has been an important commodity for the island, but heavy harvest pressure has pushed the fishery to overexploited status.
- Sea cucumbers play a crucial role in the marine ecosystem by providing food to other species and adding nutrients and pH balance in waters around coral reefs and other shallow-water ecosystems.
Illegal bottom trawling widespread inside Mediterranean marine protected areas
- A new “atlas” reveals widespread illegal bottom trawling inside Mediterranean marine protected areas.
- The atlas, an interactive online map, shows thousands of days of apparent bottom-trawling activity in areas where it is banned, in 2020 and 2021.
- Bottom trawlers can damage the seabed, destroy coral and sponge habitats, and catch unintended species at a high rate.
- The findings demonstrate “the lack of enforcement and transparency in the Med, which is the most overfished sea in the world,” an atlas coordinator told Mongabay.
No requiem for sharks just yet as nations push to protect species from trade
- Nations party to CITES, the global convention on the trade in endangered species, are supporting three proposals to list dozens of sharks and rays from three families onto Appendix II of the convention.
- While a CITES Appendix II listing would not prohibit trade outright, it would regulate it by requiring export permits, which would help mitigate overexploitation.
- A recent study found that more than a third of sharks, rays and chimeras are threatened with extinction, making them the second-most threatened vertebrate group, after amphibians.
- The proposals are up for discussion at CITES’s 19th Conference of the Parties, or CoP19, taking place from Nov. 14-25 in Panama.
Negotiations to conserve Antarctic Ocean end in stalemate on many issues
- The 41st annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with conserving marine life in the Southern Ocean and managing fisheries there, ended Nov. 4 with little progress made on several key issues.
- In 2009 CCAMLR committed to creating a network of marine protected areas to preserve Antarctic ecosystems. It established one that year and another in 2016, but since then China and Russia have repeatedly blocked the creation of additional protected areas, as well as other conservation-related measures.
- The commission also failed to reach the consensus required to enact new regulations for the krill and toothfish fisheries, or to protect a vast nesting area for icefish discovered earlier this year.
- CCAMLR members did agree to designate eight new vulnerable marine ecosystems, areas home to slow-growing organisms such as corals, sponges, brittle stars and feather stars that are now permanently protected from bottom fishing.
Did climate change really kill billions of snow crabs in Alaska?
- In October 2022, the National Oceanic and Atmospheric Administration (NOAA) announced that the lucrative snow crab fishery in the Bering Sea would close for the first time, following a population decline of 80% between 2018 and 2022.
- While fisheries managers and biologists say climate change is to blame for the species’ retreat, some fishers and crab experts suggest that trawling bycatch and other fishing activity may have played a role in the snow crab’s decline.
- The fishery’s closure has amplified a chorus of concerns about Alaska’s trawling industry and the knowledge gaps around its potential impact on fisheries.
Small island, big ocean: Niue makes its entire EEZ a marine park
- In April, Niue, a small island nation in the South Pacific Ocean, designated its entire exclusive economic zone — an area about the size of Vietnam — as a multiple-use marine park called Niue Nukutuluea.
- Forty percent of the park is a no-take marine protected area; a smaller slice is managed by local villages. And about 56% of the park is a general-use zone where commercial fishing and other activities, including possibly deep-sea mining, could take place.
- The country has developed an unusual mechanism to fund the park, and is gathering support to confront the perennial challenge of monitoring and compliance in technologically advanced ways.
New Zealand convicts company of illegal trawling in high seas restricted area
- In late August, a court in Aotearoa New Zealand convicted a subsidiary of one of the country’s major seafood companies of illegal trawling in a closed area in the Tasman Sea between New Zealand and Australia.
- The judge fined the company NZ$59,000 (about $33,000) and the skipper NZ$12,000 (about $7,000), and seized the vessel.
- It’s the fourth case in the past five years where courts convicted New Zealand-flagged vessels of illegal trawling.
- The recent conviction comes amid an ongoing debate about trawling in New Zealand, with campaigners calling for a ban on bottom trawling on submarine mountains, and the industry disputing their arguments and resisting aspects of the proposed change.
Deep dive uncovers previously unknown underwater ecosystem in Maldives
- Scientists recently identified a previously undiscovered marine ecosystem in the waters around the Maldives, known as the “trapping zone,” about 500 meters (about 1,600 feet) below the surface.
- The researchers say the trapping zone refers to a region of subsea vertical cliffs and shelving terraces that “trap” small, migrating mesopelagic organisms, which attract pelagic predators like sharks, tuna and large fish.
- Prior to this mission, very little was known about the Maldivian sea below 30 m (about 100 ft), despite the country’s total area consisting 99% of water.
- The researchers say trapping zones likely exist in the waters around other oceanic islands with similar topography, and that they’re already gathering evidence of such an ecosystem in the waters of the Chagos archipelago, south of the Maldives.
Why fish are disappearing from Amazonian waters
- From the coastline to freshwater streams, people living in Amazonia say industrial fishing, deforestation, hydroelectric dams and climate change have reduced fish populations.
- Industrial fishing is one of the main explanations for the low numbers. Fishermen report that large boats are trawling with nets up to 30 kilometers (18.6 miles) in length that do not allow fish to reach the shore.
- Other challenges local fishers are facing have to do with the effects of climate change on rivers and mangroves, including increased temperature and lower pH and oxygen levels in the water, which make it harder for species to survive.
- Hydroelectric dams are a threat to inland Amazonian fish species because they interrupt migratory flow, leading to genetically compromised populations; this phenomenon has been seen in the Xingu River, which, dammed by the Belo Monte hydroelectric plant, is suffering from falling fish reproduction rates.
To boost fish catches, try banning fishing, new study shows
- A new study has found that the Papahānaumokuākea Marine National Monument in Hawai‘i, the world’s largest contiguous marine protected area, increased the catch rates of yellowfin and bigeye tunas in nearby fisheries due to a “spillover effect.”
- Between 2016 and 2019, catches of yellowfin tuna increased 54% in waters near the MPA, and catch rates for bigeye tuna rose by 12%.
- Another study found that MPAs not only increase the catches for fisheries, but also yield other benefits, like the enhancement of carbon sequestration and biodiversity.
- However, both studies suggest that the best results come from fully protected MPAs that don’t allow fishing, and that underprotected MPAs yield “little to no social or ecological benefits.”
Fish-feed industry turns to krill, with unknown effects on the Antarctic ecosystem
- The Antarctic krill fishing industry has been growing in the past two decades.
- The global growth of fish farming is driving the demand for Antarctic krill as an alternative to wild fish in fish feeds, amid the depletion of many wild fish stocks.
- Independent scientists say the krill fishery could have a detrimental effect on Antarctica’s predator populations, which are also suffering from the impacts of global warming.
- The krill industry is expanding its fleet and planning to significantly increase catches in the next few years.
Panama restricts information on sanctioned boats, evading transparency
- Over the course of three months earlier this year, Mongabay and Bloomberg Línea requested information from the Panamanian authorities concerning inspections carried out on Panama-registered boats and the resulting sanctions that were imposed.
- Panamanian authorities denied much of the request, claiming it concerns information of a restricted nature.
- The authorities did grant a request to review vessel records at the location where they are held, but prohibited the reporting team from taking photographs or making photocopies. The team found paper records arranged in thick folders with pages in neither ascending nor descending order, which made the search a complex task.
- Lawyers who specialize in fishing and environmental issues say the authorities should release the information, and that the difficulty accessing it hinders efforts to uncover illicit activities.
As Indonesia protects more marine areas, top priority is management: experts
- As Indonesia aims to protect more of its seas, scientists say in a new paper that effective management of these marine areas must be the government’s top priority in a world faced with global climate change and biodiversity crises.
- The researchers say that marine protected areas must protect the natural resources, provide long-term benefit to local people, and be equipped with a zoning system, monitoring, surveillance, adequate staff capacity, facilities, and self-financing.
- The Indonesian government has pledged to secure 10% of the country’s territorial waters towards biodiversity protection and sustainable use by the end of this decade, and triple the size by 2045.
- The move is part of the country’s contribution to the global “30 by 30” conservation goal, which aims to protect 30% of the world’s seas and lands by 2030.
Panama: A ‘flag of convenience’ for illegal fishing and lack of control at sea
- Why would a Chinese ship want to fly the Panamanian flag? This practice is known as flying a “flag of convenience” and although it’s legal, experts say it often lets shipowners benefit from lax auditing and is closely associated with illegal fishing because it can hide the identity of a vessel’s true owners.
- Mongabay Latam and Bloomberg Línea investigated violations and alleged crimes committed by the fleet of ships flying the flag of Panama, the country whose flag is most commonly used.
- Our analysis of an official database shows that some of the vessels operating under the Panamanian flag do business with a Chinese company that has one of the global fishing industry’s longest criminal records.
A ‘super reef’ recovery raises hopes — but also questions about its resilience
- Experts documented the substantial recovery of coral reefs around the southern Line Islands in the central Pacific after the area was hit by a large-scale coral bleaching event in 2015 and 2016.
- Many factors may have contributed to the reef’s recovery, including the fact that the reef is seemingly untouched by human activity, which helped maintain a healthy and resilient ecosystem.
- But other experts question whether this reef would be able to recover after more frequent bleaching events, which are predicted to increase as global temperatures continue to rise.
Podcast: ‘Destructive & flawed’: Claire Nouvian on bottom trawling’s many impacts
- Goldman Environmental Prize winner Claire Nouvian joins the Mongabay Newscast to discuss the many impacts of bottom trawling and a historic policy shift by the European Commission to rein in the practice.
- This kind of fishing is known for damaging deep-water coral reef ecosystems and marine biodiversity, and for having a heavy carbon footprint.
- Nouvian discusses the successful activism of her organization that won an EU-wide ban on bottom trawling below 800 meters (875 yards) after seven years of grassroots organizing. She also discusses what individuals can do if they want to support more sustainable fishing practices.
Indonesia’s sustainable fisheries push sails into storm in Java Sea
- Civil society activists have questioned whether a sanctioned alternative to the seine net will help fish stocks recover in Indonesia’s fishing zones.
- Fishers on Java’s northern coast are struggling to adapt to sustainability changes announced by Indonesia’s fisheries ministry.
- Cases of conflict between seine net fishers and smaller local fishing boats continue to be reported.
Java fishers struggle with seine net ban amid rising costs, falling profits
- Fishers on the north coast of Java are struggling to adapt to a ban on the seine net, with many boats confined to port after the government ceased issuing new permits to seine net fishers.
- Java fishers report declining catch volumes from the alternative net.
- Some boat captains fear bankruptcy as cash flow pressures mount.
Indonesia to update conservation efforts for aquarium favorite cardinalfish
- Indonesia’s fisheries ministry says it is working on a new conservation road map for Banggai cardinalfish (Pterapogon kauderni), a popular species in the aquarium trade globally that is found only in the waters around the country’s Banggai Archipelago.
- The fish is caught in large numbers — an estimated 500,000 to 900,000 individuals annually — and is exported mainly to the United States and Europe.
- The updated conservation plan will evaluate the previous five-year plan for the cardinalfish, and use this to inform the national strategy for the next five years, the ministry said.
- The cardinalfish’s habitat, the Banggai Archipelago, is considered to be in the heart of the Pacific Coral Triangle, which is home to the highest diversity of corals and reef fishes anywhere on the planet.
U.S. charts course for adopting ropeless fishing to reduce whale deaths
- The National Oceanic and Atmospheric Administration (NOAA) has published a report laying out a strategy to allow the use of “ropeless” or “on-demand” fishing gear off the U.S. East Coast with the goal of reducing entanglements of the critically endangered North Atlantic right whale.
- The gear uses acoustic signals to locate and retrieve gear, reducing the amount of time that vertical lines are present in the water column, where they can ensnare right whales and other types of marine life.
- Right whale numbers in the North Atlantic have declined precipitously in the past decade, as collisions with ships and entanglements have killed individuals and hampered the species’ ability to reproduce.
- NOAA’s Ropeless Roadmap estimates that on-demand fishing gear can substantially diminish the risk to right whales, while allowing economically and culturally important fisheries of the northeastern U.S. to continue.
Europe moves to protect deep-sea sites in Atlantic from bottom fishing
- The European Commission recently announced that it will protect 16,000 square kilometers (6,200 square miles) of the deep sea — known as “vulnerable marine ecosystems” — in EU waters in the northeast Atlantic Ocean by prohibiting bottom fishing in these areas.
- This move is a key component to the Deep-Sea Access Regulation, a plan adopted by the EC in 2016 to protect deep-sea environments in EU waters. However, the regulation stipulated that vulnerable marine ecosystems should be protected by 2018, so its implementation comes four years late.
- The fishing sector has warned that this move will threaten the future of bottom fishing and impact more than 10,000 fishers.
- Conservation experts have welcomed this announcement, despite its lateness, saying that such a move is essential in protecting fragile and ecologically important deep-sea environments.
Thailand’s contentious plan to curtail bottom trawling unfolds in slow motion
- To rebuild its dwindling fish stocks, Thailand has implemented a series of reforms to its fishing sector since 2015, reining in illegal fishing while curtailing catches and the size of its commercial fishing fleet.
- In July, the Thai government announced a ban on new registrations for bottom trawlers, a particularly destructive and indiscriminate kind of fishing vessel, coupled with a $30 million buyout program for them and other gear types.
- Small-scale fishers say the reforms don’t go far enough to protect fish stocks, while commercial fishers say the new rules are hobbling their industry and should be scrapped.
Greenland’s sustainable halibut fishery may threaten newfound corals, sponges
- Industrial trawling for halibut in the Davis Strait off western Greenland is currently done in a certified sustainable manner, but new studies suggest it may be doing long-term harm.
- The studies describe assemblages of unique marine life on the seafloor both inside and near the halibut fishing zones that could potentially be considered “vulnerable marine ecosystems.”
- Scientists have called for protection of these potential VMEs, but acknowledge that ending bottom trawling altogether isn’t a viable option when fishing accounts for 93% of Greenland’s exports.
- Fishing industry stakeholders say they’re confident that existing rules designed to help the halibut fishery meet sustainability requirements will be sufficient to spare these potential VMEs, and point to a new management plan for the entire Greenlandic seabed that is in development as a way to strengthen protections.
Illegal fishing, worker abuse claims leave a bad taste for Bumble Bee Seafood
- A new report published by Greenpeace East Asia has found that Bumble Bee Seafoods and its parent company, Fong Chun Formosa Fishery Company (FCF) of Taiwan, are sourcing seafood from vessels involved in human rights abuses as well as illegal, unreported and unregulated (IUU) fishing practices.
- It found that 13 vessels supplying seafood to Bumble Bee violated Taiwanese fishery regulations, and were even on the Taiwan Fisheries Agency’s (TFA) list of vessels involved in IUU fishing, and that many supply vessels were involved in issues of forced labor and human trafficking.
- Both Bumble Bee and FCF have sustainability and corporate social responsibility policies in place.
Maldives shark-fishing ban tested by ebbing support from small-scale fishers
- A 2010 blanket ban on shark fishing in the Maldives doesn’t enjoy support from artisanal reef fishers, a new study suggests.
- Many fishers blamed sharks for stealing their catches, eating into their earnings, and damaging their fishing equipment — problems they perceive have worsened since the creation of a shark sanctuary.
- These negative perceptions could result in lower compliance with fishing restrictions and undermine efforts to revive shark populations in Maldivian waters.
- Pole-and-line skipjack tuna fishers reported the greatest support for the shark fishing ban because sharks corral tuna to the ocean surface, making them easier to catch.
Healthy mangroves build a resilient community in the Philippines’ Palawan
- According to historical accounts, the fisheries of Malampaya Sound in the Philippines’ Palawan province were once so rich it was difficult to wade to shore without stepping on crabs.
- This bounty fueled migration to the area from across the Philippines, and by the turn of the 20th century, much of the areas’ mangroves had been cleared or degraded, leading to a decline in fish catches.
- From 2011-2013, mangrove restoration efforts were initiated as part of the Philippines’ National Greening Program, but, as elsewhere in the country, the initiative performed far below target.
- Today, however, thanks to ongoing outreach initiatives, community partnerships and Indigenous belief systems, the importance of preserving mangroves is widely recognized and the area’s coastal forests and fisheries are seeing a recovery.
Indonesia announces plan to protect 10% of its seas by 2030, and 30% by 2045
- Indonesia will expand its marine protected area coverage to 325,000 square kilometers (125,000 square miles) by the end of this decade, or 10% of its total territorial waters, the fisheries ministry says.
- From 2030 to 2045, the government plans to triple that coverage to 975,000 km2 (376,000 mi2).
- An oceans conservation activist has welcomed the plan, but says the government needs to be able to square it with a recently announced fisheries management policy that critics say threatens the sustainability of fish stocks.
- The activist also emphasized the need to ensure the quality of the protection rather than the quantity.
In Sumatra, rising seas and sinking land spell hard times for fishers
- Fishers operating near the port of Belawan on the Indonesian island of Sumatra are reporting declining catches and a hit to their livelihoods from tidal flooding.
- The flooding has grown more frequent and severe, exacerbated by rising seas and the clearing of mangrove forests for oil palm plantations.
- Traders who buy local catches have also been affected by the flooding, which can cut off commercial transport routes.
- This region of northern Sumatra is one of the areas targeted by the Indonesian government for mangrove restoration, but until that yields results, the fishers say they’re essentially helpless.
Love ‘em and loathe ‘em: Mediterranean grapples with tasty, voracious invasive crabs
- Two invasive blue crab species have recently settled in the Mediterranean.
- Both species are voracious predators that disrupt bottom habitats, shred fishers’ nets and ruin their catches. They’re also edible.
- Mediterranean countries are considering whether to target the invasive crabs to control them, or embrace and even protect them as a new socioeconomic resource for the future.
- This story was produced with the support of the Pulitzer Center.
‘Spiderwebs’ to the rescue for Indonesia’s coral reefs
- A small-scale project in Indonesia is seeing success in efforts to restore coral reefs damaged by blast fishing.
- Lightweight cast-iron rods form underwater “spiderwebs” that are placed onto existing reefs, with new coral grafted onto the structure.
- Proponents of the project say the benefits are already tangible, but add that to make them last, there needs to be an end to destructive fishing practices.
Amid rising pressure, Indonesia’s sea-based communities adapt to change
- A growing population, destruction of coral reefs, and the loss of traditional fishing methods all threaten the way of life of traditional communities in Indonesia whose livelihoods have for generations depended on the sea.
- Among them are the seafaring Bajo people, nomads of the waters between Indonesia, Malaysia and the Philippines, who say their resources “are declining day by day.”
- In the Sangihe Islands in the archipelago’s northeast, modern nets and outboard motors have replaced the bamboo gear and sampan boats used by local fishing communities.
Record-breaking seafood production must undergo a ‘blue transformation’: FAO
- The U.N.’s Food and Agriculture Organization released its latest “State of World Fisheries and Aquaculture” (SOFIA) report in late June. The flagship report, released biennially since 1995, provides data, analysis and projections that inform decision-making internationally.
- Fisheries and aquaculture production rose around 3% since 2018, to an all-time high of 214 million metric tons in 2020, with a first-sale value of around $406 billion, the report found. Growth was driven by a 6% rise in aquaculture production, while wild fish capture dropped by almost 4.5%.
- The number of sustainably fished marine fish stocks continued a long-term decline; less than 65% of stocks are now being fished within biologically sustainable levels, down from 90% in the 1970s.
- The new report outlines a “blue transformation” that aims to make both the aquaculture and wild fisheries sectors more sustainable and productive so they can help feed a human population projected to reach 10.9 billion by the end of this century.
Fish-farming practices come under scrutiny amid surge in aquaculture
- A recent investigative report claims to reveal for the first time the poor conditions, including mistreatment of fish, in some Indonesian fish farms.
- While activists and industry figures are at odds over the magnitude of the problem, both agree that aquaculture throughout Asia needs to be better managed while supporting small-scale farmers to address the issue of fish welfare.
- Production of farmed fish grew by 527% worldwide from 1990-2018; production of wild-caught fish during the same period rose by just 14%.
WTO ban on ‘harmful’ subsidies won’t impact small-scale fishers, Indonesia says
- Indonesia will continue subsidizing its small-scale fishers in the wake of a recent deal struck by members of the World Trade Organization to end “harmful” subsidies.
- The legally binding agreement prohibits WTO member states from giving subsidies that support the fishing of already-overfished stocks and curbs those that contribute to illegal, unregulated and unreported (IUU) fishing at sea.
- Indonesian subsidies to fishers — in the form of insurance, fishing gear and fuel subsidies, among others — amount to $92 per fisher annually, much less than in the U.S. ($4,956), Japan ($8,385) or Canada ($31,800).
- Indonesia is the second-biggest marine capture producer, after China, harvesting 84.4 million metric tons of seafood in 2018.
Experts fear end of vaquitas after green light for export of captive-bred totoaba fish
- After a 40-year prohibition, international wildlife trade regulator CITES has authorized the export of captive-bred totoaba fish from Mexico.
- Conservationists say they fear this decision will stimulate the illegal fishing of wild totoabas and that this will intensify the threats facing the critically endangered vaquita porpoise.
- Only around eight individual vaquitas remain alive; they regularly drown in nets set illegally for totoabas in the Upper Gulf of California, where the two species overlap.
- The swim bladders of totoabas are sold in Asian markets at exorbitant prices because of their value as status symbols and their supposed medicinal properties.
In Costa Rica, unlicensed fishers and regulators unite over a common enemy
- Artisanal fishers on Costa Rica’s southern Caribbean coast have been operating in a legal gray area since 2005, when the government ordered a freeze on fishing licenses pending a study on fishing sustainability.
- Now, however, they’ve come back into favor, thanks to their efforts to tackle the explosive growth of an invasive species: the red lionfish.
- The lionfish has no natural predators in these waters, and its proliferation threatens commercially important species such as snapper, lobster and shrimp.
- Today, fishers’ associations are working with regulators on joint efforts to fight back the lionfish tide and compile fisheries data, in exchange for licenses.
WTO finally nets deal curbing fisheries subsidies, but tables key bits for later
- Negotiators agreed on a deal to curb “harmful” government fisheries subsidies that are compromising fish populations and damaging the marine environment.
- The talks among the World Trade Organization’s 164 member states were scheduled for June 12–15, but overtime negotiations didn’t conclude until early June 17.
- The new agreement addresses certain harmful subsidies. But in the interest of reaching consensus, negotiators put off dealing with others where agreement proved elusive.
- Many observers are welcoming the agreement as “historic,” coming as it does two decades after talks began in 2001, even as others point out “major weakness.”
Sea restoration projects quilt a ‘mosaic of habitats’ with striking results
- The concept of restoring more than one type of marine habitat at a time — such as oyster reefs, seagrass meadows and salt marshes — is becoming increasingly popular as scientists and conservationists learn about the advantages of this approach.
- Many studies clearly show the mutual benefits that integrated habitats provide to each other, as well as the larger benefits offered to the ecosystem.
- Yet other studies show mixed results, drawing attention to the complex nature of this approach.
- Numerous seascape restoration projects are taking place around the world, including in the coastal bays of Virginia, U.S., the sea off the coast of South Australia, and the estuaries and lochs in the U.K.
Ray care center: Indonesia’s Raja Ampat a key nursery for young reef mantas
- Scientists have published new evidence confirming that Wayag Lagoon in Indonesia’s Raja Ampat archipelago is a globally rare nursery for juvenile reef manta rays (Mobula alfredi).
- Visual observations from 2013 to 2021 show that juvenile reef manta rays are repeatedly encountered in the small, shallow and sheltered lagoon, without the presence of adult individuals; the young rays spend months at a time inside the lagoon, never venturing out.
- The findings have prompted marine authorities in Indonesia to start revising the management of the lagoon to safeguard the manta nursery zone, with regulations being drawn up to limit disturbances to the young rays.
- Both oceanic and reef manta rays are protected species under Indonesian law, which prohibits their catch and the trade of any of their body parts.
‘Why sharks matter’: Q&A with author and shark biologist David Shiffman
- In a new book, conservation biologist David Shiffman explores the importance of sharks to the world’s marine ecosystems.
- An enthusiastic “deep dive” into the latest research, “Why Sharks Matter” also addresses the threats sharks face and what scientists, NGOs and the public can do to support shark conservation.
- Mongabay caught up with Shiffman just before the May 24 release of the book.
In Sierra Leone, local fishers and foreign trawlers battle for their catch
- At wharfs across the Freetown peninsula in Sierra Leone, local fishers say in recent years it’s become harder to get a good catch. They blame foreign trawlers for overexploiting the country’s fish stocks.
- Sierra Leone’s Ministry of Fisheries and Marine Resources says it has systems meant to curb illegal, unreported, and unregulated fishing, but enforcement remains a challenge.
- In 2019, China signed a fisheries agreement with Sierra Leone that includes a promise to build a $55 million harbor, but some fishers say boats owned by its citizens are among the worst offenders.
For reef mantas, Indonesia’s Komodo National Park is a ray of hope
- A new study has found that Komodo National Park in Indonesia has an aggregation of 1,085 reef manta rays, currently classified as a vulnerable species.
- Experts say that locations such as Komodo will play an important role in safeguarding the species from extinction.
- Manta rays are under pressure from fishing activity, including targeted fishing and bycatch.
- However, experts say the species is also impacted by tourism and the changing dynamics of the ocean.
Wage-related abuses in fishing industry exacerbated by pandemic response
- The COVID-19 pandemic left migrant fishers in Asia, already a highly vulnerable section of the workforce, with less income and at higher risk of labor abuses, a new report says.
- The brief, commissioned by the International Labour Organization and authored by Cornell University researchers, looked at workers’ experiences in the fishing and seafood-processing industries of Japan, South Korea, Thailand and Taiwan from March 2020 to March 2021.
- Common issues they uncovered included employers paying wages below the legal minimum, making illegal wage deductions, deferring wage payments, and not paying wages upon termination of employment.
- Labor shortages caused by border closures due to the pandemic should have given workers more leverage in wage negotiations, but this wasn’t the case, the researchers found.
Indonesia cancels fisheries infrastructure projects in Maluku region amid lack of funds
- Indonesia doesn’t have the money to build the National Fish Bank or a new Ambon port, two infrastructure projects the national government had promised in the province of Maluku, a minister announced last month.
- The obstacle for the National Fish Bank project relates to its chosen location, near an underwater volcano and abandoned mines from World War Two.
Murky provenance of a Chinese fleet clouds Madagascar shrimp fishery
- Thirty-nine trawlers are licensed to catch up to 4,170 metric tons of shrimp in Madagascar’s waters during the 2022 campaign, which officially began on March 1.
- Chinese-owned company Mada Fishery, which holds eight exploration rights did not apply to catch shrimp this year, and its eight vessels are now sitting idle.
- Three of the vessels were previously engaged in fishing violations in the Gambia, and under Malagasy law should not be eligible to fish in Madagascar now — unless there’s been a change in their ownership.
- But a murky document trail and general lack of transparency into the vessels’ ownership makes it unclear whether that has happened; transparency advocates say the implementation of simple measures would have made a significant difference in the investigation of Mada Fishery.
Scaling Palauan tradition to regional fisheries: Q&A with Noah Idechong
- After training as a traditional hunter and fisherman in his village in Palau as a boy, Noah Idechong has since become a “bit of a legend” in Pacific marine conservation.
- He has been a government official, an activist, a politician, a legislator, and the founder of a domestic conservation NGO. Currently, he’s the executive director for Micronesia and Polynesia at the international conservation NGO The Nature Conservancy.
- In all of these roles, Idechong has focused on one main thing: championing the traditional systems the communities of Palau employ to protect and conserve the archipelago’s rich marine biodiversity and domestic fisheries.
- Today, he’s applying that ethos at a regional scale as he helps build more sustainable regional tuna fisheries that benefit the Pacific island nations in whose waters the tuna swim, rather than foreign fishing enterprises.
Boats behaving badly: New report analyzes China’s own fisheries data
- China’s distant-water fishing fleet, which operates on the high seas and in other countries’ waters, is far bigger and catches far more seafood than those of other nations.
- As a result, and also because of numerous high-profile cases of illegal behavior, the Chinese fleet receives intense scrutiny from international NGOs and the media.
- A new report, based mainly on data China released since enacting transparency measures in 2017 as well as a database of global fisheries violations and crew interviews, identified hundreds of fisheries offenses committed by the fleet between 2015 and 2019, and details a range of human rights abuses and environmentally destructive fishing practices.
- However, some experts say that although the Chinese fleet is by far the biggest, vessel for vessel its behavior isn’t all that different from other fleets, and that all share responsibility to reform.
Troubled waters: A massive salmon farm off the coast of Maine is stalled
- Norwegian-backed American Aquafarms was slated to build the largest salmon farm in North America along the coast of the U.S. state of Maine, using a closed-pen system said to minimize waste.
- But opponents say the closed-pen technology is untested at such a large scale, and warn that environmental impacts will devastate the pristine waters.
- The proposed salmon farm would have been right at the shorelines of Acadia National Park, threatening the region’s untarnished views and noise pollution.
- Currently, the project is indefinitely delayed as state officials terminated the lease application on April 19th. However, with Maine leasing the ocean for only $100 an acre ($250 a hectare) per year, opponents worry that future investors will see the coast as a lucrative target.
Pilot program tries to get U.S. aquariums to raise their own fish, not catch them
- A collaboration between the New England Aquarium in Massachusetts and Roger Williams University in Rhode Island has developed protocols for breeding marine aquarium fish, including five species never before raised in captivity.
- Though some fisheries for ornamental fish are responsibly managed and benefit local economies, harmful collection practices like cyanide fishing and overcollecting can harm ecosystems.
- Aquaculture of ornamental fish can improve fish welfare, reduce the spread of disease, take the guesswork out of fish sourcing, and reduce impacts on wild populations.
Stranded coal barge spills cargo, disrupts fishery in Indonesian waters
- An Indonesian coal barge that ran aground off East Java has reportedly spilled much of its cargo and disrupted the local fishery.
- Local fishers blame the spill for turning the water in the area dark and affecting their fishing activities.
- An environmental group has called for an investigation by fisheries and environmental agencies into the incident.
- Indonesia is one of the world’s biggest producers of coal, but has paid a heavy price for that standing, including the massive deforestation wrought to mine the fossil fuel, as well as the numerous environmental and safety incidents associated with transporting and burning it.
Oil spill contaminates wildlife, beaches and protected areas in Peru
- On Jan. 15, a refinery owned by Spanish oil company Repsol spilled nearly 12,000 barrels of oil into the sea off Lima, Peru, as it was pumping the oil from a tanker.
- Experts have questioned why the refinery of La Pampilla was operating that day, when there were unusually high waves caused by the Tonga volcano eruption and tsunami.
- Peru’s Environmental Evaluation and Enforcement Agency (OEFA) has fined Repsol for similar spills on at least three prior occasions, and this time the company could be hit with more than $37 million in fines.
- The spill has spread beyond the Lima coast and out toward islands that are part of a network of protected nature reserves, posing serious threats to marine life and to artisanal fishermen.
The Great Barrier Reef is bleaching — once again — and over a larger area
- The Great Barrier Reef is currently experiencing its sixth mass bleaching event, and the fourth event of this kind to happen in the past six years.
- Based on aerial surveys that were concluded this week, bleaching has affected all parts of the Great Barrier Reef, with the most severe bleaching occurring between Cooktown, Queensland, and the Whitsunday Islands.
- Sea surface temperatures around the Great Barrier Reef have been higher than normal, despite the region going through a La Niña climate pattern, which usually brings cooler, stormier weather.
- Climate change remains the biggest threat to the Great Barrier Reef and other reefs around the world, experts say.
Study links many reported fisheries crimes to just a few repeat offenders
- A new study in the journal Science Advances analyzed roughly 8,000 fisheries offenses reported globally between 2000 and 2020, a database the authors call the “largest existing repository” of reported fisheries offenses.
- The study shows that a small number of companies may be responsible for a large chunk of international industrial fisheries crimes.
- It also shows that the vessels committing abuses, such as unauthorized fishing and human rights and labor violations, often engaged in more than one offense.
- Illegal fishing accounts for one fourth the value of all landed seafood products, roughly $30 billion globally. It contributes to the depletion of fish and other marine wildlife populations.
Fourth round of U.N. talks fail to finalize a treaty to manage the high seas
- U.N. member states met this month in New York to hash out a treaty governing the sustainable management of the high seas, resource-rich international waters that span about two-thirds of the ocean.
- Hopes were high that after 10 years of discussion and three previous negotiating sessions, delegates to the meeting would finalize a legally binding treaty.
- Talks ended March 18 with no deal, amid a failure to reach consensus on several key points, including how to establish marine protected areas on the high seas.
- A movement to protect 30% of the ocean by 2030 depends on the swift completion of a high seas treaty, and observers say a deal remains within reach by the end of the year.
‘Small-scale fishers have a Ph.D. in the ocean’: Q&A with Vatosoa Rakotondrazafy
- Traditional fishers along Madagascar’s coastline are grappling with falling fish stocks, cyclones, and competition from industrial trawlers, mostly owned by foreigners.
- In an attempt to better manage the country’s marine wealth and secure local fishers’ rights, communities banded together to form Mihari, a network of locally managed marine areas (LMMAs) that leans heavily on traditional ocean knowledge.
- As Mihari’s national coordinator for six years Vatosoa Rakotondrazafy supported a campaign to reserve fishing areas for small scale fishers and helped create a space for women to fully participate in decision-making.
- She spoke with Mongabay recently about the challenges facing fishing communities, their depth of marine knowledge, and the prospects for securing their fishing rights.
Four new MPAs in Maluku boost Indonesia’s bid to protect its seas
- Indonesia’s Ministry of Marine Affairs and Fisheries designated four new marine protected areas in the country’s east in January.
- The new conservation areas are in the waters surrounding the islands of Tanimbar, Damer, Mdona Hiera, Lakor, Moa, Letti and the Romang in Maluku province.
- The newly designated MPAs are home to threatened and protected species, including the green turtle, the scalloped hammerhead shark, and an abundance of coral reefs and other marine ecosystems.
- The four new MPAs bring the Indonesian government two-thirds of the way toward its goal of ensuring “effective management” of 10% of national waters by 2030.
‘There’s hope’ for North Atlantic right whales: Q&A with filmmaker Nadine Pequeneza
- The documentary “Last of the Right Whales” seeks to bring the plight of these gentle giants to audiences that are largely unaware of how close to extinction the species is today.
- North Atlantic right whales (Eubalaena glacialis) were historically decimated by hunting, but the biggest threats to the species today are ship strikes and entanglement in fishing gear.
- There are an estimated 336 of the animals remaining, more than 80% of which have experienced entanglement in ropes tethered to fishing gear on the sea floor.
- Documentary director Nadine Pequeneza spoke with Mongabay about bringing these threats to public attention, the importance of engaging with and not vilifying fishers, and why she holds out hope for the whale’s future.
Indonesia to tighten regulation of tuna harvest in bid for sustainability
- Indonesia plans to develop a nationwide harvest strategy for its world-leading tropical tuna fishery.
- The fisheries ministry says having a set of rules in place under such a strategy will be crucial to protecting the country’s wild tuna stock.
- The move will also help the government’s ongoing push to achieve sustainability certification for its fisheries and subsequently open them up to the growing global demand for eco-labeled seafood.
- Indonesia is the world’s biggest producer of tuna, but its fisheries have long been plagued by poaching and destructive fishing practices.
Seychelles embraces transparency in fisheries, but gaps in data and action remain
- Launched in 2015, an enterprise known as the Fisheries Transparency Initiative (FiTI) is working to make fisheries more transparent and sustainable.
- The Seychelles joined FiTI in 2017 and recently released its second report to the initiative, which details its government’s efforts to increase public access to information about the management and direction of its fisheries.
- The information released in this report has substantially increased fisheries transparency in the Seychelles, and elucidated the national and foreign fishing interests that are straining local stocks, including yellowfin tuna.
- However, experts say there are still many information gaps and issues that need to be overcome in fisheries management in the Seychelles.
Bleached reefs still support nutritious fish, study finds
- A recent study published in the journal One Earth looked at the nutrients available in fisheries in Seychelles before and after bleaching killed around 90% of the island nation’s coral in 1998.
- Warming ocean temperatures have caused mass bleaching of corals across the tropics, sometimes causing the deaths of these reef-building animals, and the phenomenon is expected to continue as a result of climate change.
- The research found that bleached reefs continue to support fisheries that provide essential micronutrients to human communities.
In Indonesia’s Sulawesi, a community works to defuse blast-fishing crisis
- Decades of blast fishing have destroyed much of the coral reefs off Indonesia’s Lora village, reducing fish catches.
- Increased law enforcement and advocacy by NGOs has helped roll back these destructive practices, but other threats loom, including increasingly unpredictable weather and competition from large trawlers.
- A community organization is seeking to have the region zoned as a conservation area.
Changes to Madagascar’s trawling sector raise questions and hopes
- Madagascar’s auction for nearshore trawling rights has elicited concern from civil society members, who say it was not conducted transparently and opens the door for environmental mismanagement.
- Two Chinese-backed firms won nearly half of the fishing rights. One of them has brought in vessels that were caught fishing illegally in West Africa last year, and the other, which was already fishing in Madagascar, may have violated a national fishing regulation this year.
- But observers have also welcomed other aspects of Madagascar’s fisheries management overhaul this year.
- These include the creation of the Ministry of Fisheries and the Blue Economy, the appointment of scientist and civil society member as the new minister and the joining of FiTI, a global fisheries transparency initiative.
Madagascar’s small fishers cheer new trawl-free zone, but do trawlers obey it?
- Madagascar in July imposed a prohibition on industrial trawlers fishing in waters within 2 nautical miles (3.7 kilometers) of the country’s coast.
- Small-scale fishers, who for years have clashed with the industrial vessels, welcomed the new rule, but say the trawlers are largely ignoring it.
- Vessel-tracking data appear to corroborate their claims, with at least 14 trawlers apparently fishing in the prohibited zone along the west coast in recent months.
- An industry executive said that any incursions by his company were uncommon and accidental. Regulators say penalties will be imposed based on the severity of the violations.
Latest delay casts pall over WTO bid to end harmful fishing subsidies
- International negotiators were set to discuss ending government subsidies that lead to overfishing at the Twelfth WTO Ministerial Conference, scheduled to run Nov. 30 through Dec. 3 in Geneva, Switzerland.
- Days before it was due to start, however, organizers postponed the event indefinitely, due to concerns over the newly announced COVID-19 variant, Omicron.
- Negotiators have been struggling to close the remaining gaps in an agreement that has been 20 years in the works.
- Observers say the ongoing failure to reach agreement on fishing subsidies calls into question the WTO’s ability to adapt to a changing world and meet the U.N.’s Sustainable Development Goals.
Overfishing threatens to wipe out bowmouth guitarfish in Indonesia, study says
- A study has found that uncontrolled fishing of wedgefish, a family of rays, in Indonesia threatens to push the bowmouth guitarfish to extinction.
- The bowmouth guitarfish and the white-spotted guitarfish are the most commonly caught wedgefish species in Indonesia, with their fins supplying the shark fin trade.
- Researchers have called on the government to impose full protection of juvenile wedgefish and a reduction in catches of bowmouth guitarfish specifically to ensure their survival.
- Both the bowmouth and white-spotted guitarfish are critically endangered species, but neither is included in Indonesia’s protected species list.
New research hopes to shine a light on wedgefish, the ‘pangolin of the ocean’
- Wedgefish, a type of ray, are some of the least-known and most endangered fish in the ocean.
- A new research project in Mozambique is employing two types of tags, acoustic and satellite, to better understand two of these critically endangered species.
- Researchers aim to uncover the species’ range and habitat requirements to preserve them from extinction.
- Wedgefish are heavily targeted by the shark-fin trade, and their populations have declined precipitously throughout much of their range.
Will ‘ropeless’ fishing gear be seaworthy in time to save endangered whales?
- Perhaps fewer than 360 North Atlantic right whales are alive today, according to researchers’ estimates.
- Scientists blame the declining population on the twin tolls exacted by ship strikes and entanglement in fishing gear.
- “Ropeless” fishing gear that minimizes the number of vertical lines in the water that ensnare right whales has emerged as a potential “home run” solution to the entanglement crisis.
- But fishers, industry groups and even ardent proponents of ropeless systems say that it’s not yet a viable replacement for traditional fishing gear in every situation.
Study shows how sustainable livelihood programs for Indonesian fishers can succeed
- Projects offering alternative livelihoods to fishers in Indonesia tend to succeed when they work closely with local NGOs and link participants to markets where they can sell what they produce.
- That’s the finding of a new study that looks at what makes successful sustainable livelihoods interventions tick, including partnership with local people to develop their skills and leverage traditional resource-management knowledge.
- Projects that failed tended not to understand the social context in which they were situated, including gender dynamics, resource and land-tenure systems, and the desires of local fishers.
- The study authors say the findings highlight best practices for alternative-livelihoods projects and are important given that communities with negative past experiences of such projects are less likely to engage with them again in the future.
Kenya port and ship-breaking projects threaten livelihoods and environment
- Plans to build an industrial fishing port and a ship-breaking yard along the Wasini Channel off Kenya’s coast threaten the livelihoods of local communities who depend on fishing, seaweed farming, and ecotourism, residents say.
- Underwater drilling carried out as part of surveys for the proposed port last November damaged coral reefs, while drilling for the ship-breaking yard destroyed seaweed crops.
- Community members say they fear even more devastating impacts once the projects, which also include a smelting plant, get underway in earnest.
Trawling bycatch increases risk of marine life extinction in Brazil
- Up to 50 kilos of fish caught in Brazil are thrown away for every kilo that arrives on land; more than 400,000 tons of marine life were discarded between 2000 and 2018 in just four states.
- Less than 10% of the 25,618 fishing boats registered by the Brazilian government are monitored by satellites, and the program that tracks fishing boats by these satellites is not publicly open and not integrated with worldwide monitoring initiatives.
- At the global level, 19 countries, regions and territories have prohibited trawling in their waters, including two in South America: Chile and Peru.
Brazil a wreck on trawling control
- The country’s lack of statistics and technical information made way for greater deregulation and private sector influence in Jair Bolsonaro’s extremist government
- The lack of control amplifies the impacts of trawling, a technique that uses fine-mesh nets to “scrape” the seabed, sweeping up everything in their path; species of low commercial value return to the waters, almost always dead.
- The sardine catch in Brazil has already fallen from 80,000 tons to about 15,000 tons annually, and stocks of mullet and other species are also shrinking; commercial species that could disappear from the map jumped from 17 to 64 (376%) between 2004 and 2014.
China joins the foreign fleets quietly exploiting Madagascar’s waters
- For decades, fleets of industrial vessels from several nations have fished in Madagascar’s waters.
- Now China appears to have joined the fishing spree, sending at least 14 industrial longliner fishing vessels in the last several years, new evidence shows.
- Clues from official documents indicate that Madagascar’s government may have authorized these vessels to fish, at least since 2019.
- If so, the authorization process was not public, raising renewed concerns about the lack of transparency in Madagascar’s offshore fishing sector.
Indonesia to send more tuna vessels out into international waters
- Indonesia is boosting its tuna-fishing fleet in the high seas, taking advantage of increased harvest quotas.
- The plan is part of a five-year sustainable tuna fisheries policy update to be issued by the Indonesian fisheries ministry by the end of August.
- In addition to the fleet expansion, the ministry also has plans to adopt a tuna-harvest strategy for the country’s waters; limit the number of operating fish aggregating devices; and reduce the carbon footprint of its vessels.
- Indonesia is the world’s top producer and exporter of tuna.
Building back Miami’s Biscayne Bay: Do natural solutions hold hope?
- A massive fish kill in August 2020 was a red flag that historically troubled Biscayne Bay in Miami had passed a biodiversity health tipping point.
- Years of scattered efforts and mixed results of various conservation actors working toward the bay’s recovery have begun to fade in favor of more collaborative, inclusive efforts.
- Scientists and citizens are now focusing their efforts on creative ways to restore biodiversity in Biscayne Bay.
Conservation solutions in paradise: Jamaica’s Oracabessa Bay Fishing Sanctuary
- A group of local fishermen and tourism industry stakeholders established a fishing sanctuary several years ago in Oracabessa Bay in response to a decline in vital Jamaican coastal life like coral and herbivorous fish.
- Surveys indicate an increase in reef health due to the efforts despite challenges, and the conservation model is set to be replicated at multiple other sites in Jamaica.
Indonesian researchers study how to help rays released as bycatch survive
- Researchers in Indonesia are studying the survival rate of manta rays and devil rays released after being caught unintentionally by fishers.
- The study, which has so far tagged five of the animals with satellite trackers, aims to come up with best practices to boost the survival of these threatened rays.
- Populations of mantas and devils rays, from the genus Mobula, have been hit by the global trade of their parts, particularly their gills, for traditional medicine and food.
Sharks on a knife’s edge as Maldives mulls lifting 10-year fishing ban
- Eleven years ago, the Maldives created a 90,000-square-kilometer (34,750-square-mile) sanctuary that banned shark fishing, but fisheries minister Zaha Waheed said recently that the government may be planning to lift the ban.
- Conservationists say reopening shark fisheries in the Maldives would have devastating effects on shark populations and adversely affect tourism, which brings millions of dollars into the country each year.
- There are unofficial reports the Maldivian government will not be lifting the shark fishing ban, possibly in response to the local and international outcry.
- But a local expert says there are still grounds for concern if long-line fisheries are allowed to operate in the shark sanctuary, or if a legislative loophole is introduced that would allow shark fishing to recommence in some capacity.
From penguins to sharks to whales, swimming in circles is a surprisingly common trait
- Many marine animals are intentionally swimming in circles consecutively at a relatively constant speed more than twice, according to a new study using data from movement trackers.
- The researchers say the behavior is surprising in part because swimming in a straight line is known to be the most efficient way to move about.
- They found some of the animals swim in circles during different activities, including foraging, courtship, navigation and even possibly geomagnetic observations.
On the sea’s surface, a wealth of ocean life gets its start, study finds
- A new study found that surface slicks — moving patches of smooth water that form on the sea’s surface — host an array of species in larval form off the west coast of Hawaiʻi Island.
- The researchers identified more than 100 fish species from 54 families inside these slicks, representing 10% of all fish species ever recorded in Hawaiian waters.
- Surface slicks play a pivotal role in the marine ecosystem by providing food and shelter for larvae, and transporting them into different parts of the ocean.
- In addition to larvae, surface slicks accumulate large quantities of plastic, which has been found to be infiltrating the food chain.
When Chinook salmon is off the menu, other prey will do for endangered orcas
- A new study has found that endangered southern resident killer whales mainly consume endangered Chinook salmon, but will broaden their diet when this species isn’t available.
- The researchers obtained data through prey and fecal waste collected from resident killer whales over a 13-year period.
- Efforts to reinstate Chinook salmon populations through hatchery efforts can play an important role in supporting resident killer whale populations, although these programs need to be carefully managed to ensure that stocks are diverse, the study suggests.
Human impacts leave reefs short on sharks and long on moray eels
- A new study found that moray eels are more abundant on reefs where sharks are absent due to human pressures.
- The paper hypothesizes that moray eels might be benefiting from a reduction in predators and competition for food, although this hasn’t been proven.
- The authors say a lot more research is needed to assess the relationship between sharks and moray eels, and to understand the ecological role moray eels play in the marine environment.
A tale of two seas: Closed season is a mixed bag for Philippine sardines industry
- Since 2011, the Philippine government has imposed a closed fishing season on various major fishing grounds during the sardine spawning season.
- Implemented during the tail end of the year until March the following year, the closed fishing season has been both a boon and bane for communities.
- In the sardine capital of the Zamboanga Peninsula in the country’s south, the ban has boosted catch sizes for artisanal fishers, while in the Visayan Sea in the central Philippines, catches have dwindled.
- Experts point to different implementations of the fishing ban in the two regions and highlight the need to assess the economic implications of the measures, particularly to marginalized fishers.
In the fight to save the vaquita, conservationists take on cartels
- The critically endangered vaquita porpoise, a species endemic to the Sea of Cortez in the Upper Gulf of California in Mexico, is at severe risk of extinction due to illegal gillnet fishing for the critically endangered totoaba fish.
- Andrea Crosta of Earth League International (ELI) says the key to saving the species is arresting all criminals involved in the illegal totoaba trade, while other NGOs work to patrol the Sea of Cortez for illegal gillnet use or to introduce seafood sanctions.
- With only nine vaquita porpoises believed to be left in the world, most experts agree that this year will be critical to the vaquita’s survival.
Fishing fail: WTO negotiators flunk deadline to end harmful fisheries subsidies by 2020
- World Trade Organization member states missed a deadline to agree to curb harmful fisheries subsidies, part of the U.N.’s sustainable development goals.
- Exemptions for developing and least-developed countries, and rules concerning disputed waters are two major sticking points, among dozens that remain to be resolved.
- The missed deadline, on one of the first major sustainable development targets, may set a precedent for reaching future targets and raises questions about the WTO’s ability to facilitate the U.N. goals.
- Harmful subsidies fund otherwise economically impossible overfishing and incentivize illegal, unreported and unregulated (IUU) practices, contributing to the perilous state of global fish stocks.
Countries fall short of U.N. pledge to protect 10% of the ocean by 2020
- A decade ago, the international community pledged to protect 10% of the ocean by the end of 2020, under the auspices of the U.N. Convention on Biological Diversity.
- Despite adding new marine protected areas quickly, the international community is falling well short of that goal: only about 7.5% of the oceans is now protected, according to a generous assessment.
- Even proponents of marine protected areas acknowledge they are not always as effective as they could be.
- Conservationists are now pressing for the adoption of a more ambitious new international goal: protecting 30% of the oceans by 2030.
‘No other choice’: Groups push to protect vast swaths of Antarctic seas
- A coalition of conservation groups is advocating for the establishment of three new marine protected areas (MPAs) in East Antarctica, the Antarctic Peninsula and the Weddell Sea, which would encompass 4 million square kilometers (1.5 million square miles) of the Southern Ocean, or 1% of the global ocean.
- These proposals will be discussed at an upcoming meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which is due to take place online because of the pandemic.
- Conservationists anticipate that China and Russia may not support these MPA proposals due to fishing interests in the region, although they are optimistic that the MPAs will eventually be approved.
Hawaiian reefs lost almost half their fish to pollution and fishing
- A new study has found a 45% decline in the biomass of important fish species in West Hawai‘i’s reefs across a 10-year period.
- According to the research, sewage pollution was the biggest contributor to declining fish biomass; spearfishing, collection for the aquarium trade, and fishing using lay nets followed closely behind.
- The study will inform new management practices to protect Hawai‘i’s coral reefs, including the state’s 30 by 30 initiative, which aims to designate 30% of Hawai‘i’s nearshore waters as marine protected areas by 2030.
Sharks nearby? A bottle of seawater can hold the answer, study says
- A new study has been able to identify the presence of blacktip sharks in the waters of Terra Ceia Bay in Florida through eDNA detection in water samples.
- The water samples contained more blacktip eDNA in the spring and summer months, which is when the species uses the bay as a nursery, and less eDNA in the fall, which is when the sharks start to leave the area.
- While the current technique indicates if sharks are present in the water, it isn’t sensitive enough to provide an accurate population count.
China issues new sustainability rules for its notorious fishing fleet
- China has made the first major revisions to regulations governing its distant-water fishing fleet in 17 years.
- The new rules aim to curb illegal activity, increase transparency and improve sustainability in commercial fishing.
- As dominant nation in the global fishing industry, yet ranked worst for fishing offenses, China could have a huge positive impact through the new rules — if it enforces them, experts say.
Gray areas and weak policies mar lucrative Asian trade in live reef fish
- High demand for wild-caught reef fish from Southeast Asian countries like Indonesia, the Philippines and Malaysia to stock upscale restaurants in East Asia could be driving overfishing and depletion of fish stocks, export trends indicate.
- To ease the strain on wild fish populations, countries started adopting fish-farming practices in which they raise wild-caught grouper species in pens — a practice that is far from sustainable, a marine expert says.
- Government attempts to regulate the trade by imposing size limits and closed fishing seasons have largely fallen short, experts say.
- The COVID-19 pandemic and the civil unrest in Hong Kong, the prime market for the live reef food fish trade, have driven demand down, providing a window to aid the recovery of species like the leopard coral trout.
The first modern-day marine fish has officially gone extinct. More may follow
- The smooth handfish (Sympterichthys unipennis), an unusual species that could “walk” on its pectoral and pelvic fins, is the first marine bony fish to go extinct in modern times, likely due to habitat loss and destructive fishing practices.
- There was only ever one specimen of the smooth handfish known to scientists, which became the holotype for the entire species.
- The other 13 species of handfish are threatened with extinction due to habitat loss, pollution, destructive fishing practices, and other human-linked causes, and conservationists are stepping up efforts to protect them.
- Only four species of handfish have been spotted in the past 20 years, which has raised serious concerns for the future survival of these species.
Cook Islands to grant seabed mining exploration licenses within a year
- The Cook Islands government will allow miners to prospect for minerals on its seabed within the coming financial year.
- Officials justify the decision partly on the need to ease the country’s economic dependence on tourism, which has taken a hit from coronavirus-related travel restrictions.
- Scientists, environmental advocates and civil society organizations have expressed alarm at the plan and warned of potentially disastrous ecosystem impacts that could also hurt local fisheries.
- The Cook Islands in 2017 designated its entire exclusive economic zone (EEZ) of nearly 2 million square kilometers (772,000 square miles) as a mixed-use marine protected area, but advocates are concerned that seabed mining could contravene the objectives of the park.
Coral reef loss helps some fish grow bigger, but perhaps not for long
- A new study finds that large, herbivorous fish species, such as parrotfish, surgeonfish and rabbitfish, benefit from coral reef demise due to an increase of a food source, algal turf.
- Certain fish species grew larger in response to coral loss and increased algal turf, contributing to an increase in reef fish biomass, although the study suggests that any gains would be short-lived.
- Data for this study were collected between 2003 and 2018 off the coast of Lizard Island on the Great Barrier Reef, which experienced coral reef losses of up to 83% due to mass bleaching events and cyclone destruction during that period.
Lockdown allowed illegal fishing to spike in Philippines, satellite data suggest
- Satellite data indicate a spike in the number of commercial fishing vessels operating in waters within 15 kilometers (9 miles) of the Philippine coast — a zone that’s off-limits for commercial fishing.
- The increase coincided with the peak fishing season and the imposition of a lockdown in response to the COVID-19 pandemic, when marine patrols were reduced.
- Known as municipal waters, this coastal band is restricted to small-scale fishing, in order to protect the coral reefs and marine habitats that thrive there.
- Legislation mandating the use of the tracking devices on commercial fishing boats has been on the books since 2015, but the implementation continues to be delayed amid opposition from the industry.
Communities on Brazil’s ‘River of Unity’ tested by dams, climate change
- The Pixaim Quilombo is one of many traditional communities made up mostly of Afro-Brazilian descendants of runaway slaves. It sits at the mouth of the São Francisco River, one of Brazil’s most important waterways.
- Once a thriving community, it has been struggling for decades due to the impacts of upriver dams which reduce the river’s flow and alter aquatic migrations. As a result, one of the community’s two chief livelihoods has been sharply curtailed — the river’s fishery is in steep decline.
- Now, climate change threatens to make those struggles even greater, further changing fish populations, reducing river flow even more, and dangerously elevating the salinity of the stream as seawater intrudes. Rice, which once provided Paixim’s second major livelihood, can no longer be grown in the delta’s saltier marshes.
- Pixaim is seeing a major outmigration as subsistence livelihoods becomes more difficult. Residents there count among 18 million people residing in the São Francisco River watershed, impacted by a steadily dwindling water resource.
Mug shots and public pics join the dots of whale sharks’ Southeast Asian trips
- A study blending old and new techniques has recorded young whale sharks returning to the same spot in the Philippines after visiting Malaysia and Indonesia.
- Scientists recorded the second-biggest aggregation of whale sharks in the Philippines in Honda Bay in the province of Palawan.
- Compared to other whale shark groups in the Philippines, the one in Honda Bay is made up mostly of juvenile males that feed on small fish and krill.
- The discovery underscores the need for stronger collaboration between the Philippines, Malaysia and Indonesia, all part of the Sulu-Sulawesi Seascape Project under the Coral Triangle Initiative.
Chinese boat that dumped Indonesian crews at sea was also shark-finning: Reports
- A Chinese fishing company under scrutiny for the deadly labor abuses of its Indonesian boat crews was likely also engaged in illegal fishing, conservationists say.
- Jakarta has demanded answers for the slavery-like conditions under which the crew members worked on board a tuna boat belonging to the Dalian Ocean Fishing Co. Ltd.
- Four of the crew members died of illness, with three of them dumped at sea; photos provided by the surviving crew indicate the boat was engaged in the illegal finning of threatened shark species.
- “[Illegal] fishing and modern slavery practices at sea are two sides of the same coin,” said Greenpeace Indonesia oceans campaigner Arifsyah Nasution.
Will fish boom amid pandemic-driven fishing bust?
- The COVID-19 pandemic has created an exceptional crisis for fishing communities and the fishing industry as a whole.
- Since March 11, when the World Health Organization declared COVID-19 a pandemic, global fishing activity has been down by nearly 10% compared to the 2018-2019 average, according to a new estimate, and in some places the decline has been much greater.
- But it’s difficult to tell whether the global fishing slowdown will give marine life a chance to recover, experts say.
- Factors include the duration and timing of the slowdown, as well as whether illegal fishing may rebound in the absence of enforcement.
As COVID-19 batters fishery, Indonesia’s sharks get a respite
- The shark and ray fishery in Indonesia has largely ground to a halt as a result of plummeting demand due to COVID-19-related export restrictions and a domestic lockdown that has hit the restaurant industry.
- West Nusa Tenggara province, the heart of the country’s shark fishery and home to one of the world’s biggest markets for the species, saw trade volume drop by 68% in the first quarter of the year.
- Conservationists say this is an opportunity to evaluate and improve the fishery by beefing up monitoring and traceability to protect the sustainability of wild populations, while also supporting fishers with alternatives sources of income.
- Indonesia, which has the world’s highest diversity of sharks, allows the catch of some endangered species for domestic consumption, but loopholes effectively allow the illegal export of protected species.
Climate change makes some fish smaller, and others bigger, study finds
- A decades-long study finds that fish either increase or decrease in size in response to climate change-induced warming water, with smaller fish generally getting smaller, and larger fish generally getting bigger.
- Fish species changed size more rapidly in response to climate change, by nearly 20% for every 0.5° Celsius (0.9° Fahrenheit) of warming.
- Fluctuations in fish size could have a serious impact on the marine food web, such as making certain species more susceptible to predation.
Pandemic staple: Report links top tuna company to forced labor, illegal fishing
- A new report based on interviews with migrant fishers on three tuna fishing vessels operating out of Taiwan suggests that forced labor and illegal fishing practices continue within major tuna supply chains, despite efforts by companies and governments to stamp them out.
- The fishers’ allegations included deception, physical violence, wage deductions, debt bondage, passport confiscation, and excessive working hours, according to the report by environmental NGO Greenpeace.
- The fishers also provided evidence that the vessels took part in unlawful fishing practices, such as shark finning and transferring shark fins between vessels, according to the report.
- Two of the vessels that interviewees accused of these practices supply tuna to the Taiwan-based Fong Chun Formosa Fishery Company (FCF), one of the world’s largest tuna traders and the new owner of major U.S. canned-tuna brand Bumble Bee.
Sinking feeling for Indonesian fishers as COVID-19 hits seafood sales
- Indonesia is taking measures to prop up declining sales of fish amid a slump in demand caused by the response to the COVID-19 pandemic.
- Restaurants and shopping malls have been shut down in most large cities across the country as part of social distancing measures, leading to the decline in demand for seafood.
- Fish exports have also slowed as Indonesia, like many other countries, has restricted its trade with other affected countries.
- Indonesia had nearly 2,500 confirmed COVID-19 cases as of April 6, mostly in Java, with 209 deaths.
Coronavirus, trawls take a toll on shrimp fishery in Indonesia’s Jambi
- The Indonesian government has temporarily restricted trade with China in the wake of the global outbreak of the novel coronavirus disease,
- The move has hit the shrimp-fishing community in Sumatra’s Jambi province, which is highly reliant on the Chinese market.
- The fishermen say they’ll need government assistance to switch to other fisheries, having already invested heavily in shrimping gear.
- They’ve also called for a crackdown on trawl fishers operating in their waters.
Small steps aim to make a large ocean safer for rays
- New rules that apply to a vast swath of the Pacific Ocean aim to improve manta and devil rays’ chances of surviving encounters with tuna fishing boats.
- The measure prohibits fishers from targeting the rays or keeping the ones they catch accidentally. It also mandates that fishers release rays that survive being caught in a manner “that will result in the least possible harm.”
- Growth in demand for manta and devil ray gill plates and anecdotal reports of decreasing populations have raised concerns about the effects of overfishing, both intentional and accidental.
Investigation reveals loopholes for illegal shark fin exports from Indonesia
- An undercover reporting initiative by Indonesian media has highlighted loopholes that allow protected sharks to be sold abroad.
- Shark products, mostly fins, end up being exported to Hong Kong, China, Singapore, Japan and Thailand.
- In Indonesia, some endangered shark species are allowed for limited catch, but not for export, but traders find their way around this prohibition by concealing the fins from customs authorities.
- Indonesia is home to more than a quarter of the world’s 400 known shark species; a fifth of all shark species are endangered.
Tuna supply chains under scrutiny as Bumble Bee brand changes hands
- Last month, Taiwan-based Fong Chun Formosa Fishery Company (FCF), one of the top three global tuna traders, bought U.S. canned-tuna brand Bumble Bee Foods for $928 million.
- The acquisition will significantly boost FCF’s economic clout and give it a public face through the sale of Bumble Bee products.
- FCF president Max Chou emphasized the companies’ mutual “commitment to sustainability and global fisheries conservation.”
- But differing definitions of what constitutes sustainability in the complex tuna industry, as well as concerns over workers’ rights, suggest there’s work to do to build confidence in the environmental and ethical pedigree of the cutely cartooned tuna cans on supermarket shelves.
Any illegal fishing going on around here? Ask an albatross
- Albatrosses fitted with tiny radar-detecting trackers can help spot fishing vessels that have gone “dark” by turning off their AIS onboard tracking systems, a new study has found.
- Over a six-month period, 169 wandering and Amsterdam albatrosses fitted with GPS trackers covered more than 47 million square kilometers in the southern Indian Ocean, detecting radar signals from 353 different boats in the process.
- In international waters, 37% of the boats had no AIS signal, a clue they could be engaged in illegal activity; within countries’ exclusive economic zones, nearly 26% of the boats were without an AIS signal.
- The findings suggest the seabirds could be deployed to patrol the ocean for vessels operating illegally, complementing a growing body of detection methods.
Philippine study finds microplastics inside a commonly consumed fish
- A study of rabbitfish (Siganus fuscescens) in four coastal areas in the Philippines shows high levels of microplastics in the fish’s digestive system.
- The species is a key commodity in the Philippines, prepared both in its dried variety and its guts used as fermented sauce, increasing the likelihood that locals may be consuming the microplastics.
- An earlier study identified the Philippines as being one of the world’s biggest plastic polluters, with microplastics infiltrating seaweed and algae, which constitute food sources for rabbitfish and other fish species.
- The majority of fish observed to have microplastics in their guts came from Bais Bay, a major fishing ground that is part of one of the country’s largest marine protected areas.
Science-backed policy boosts critically endangered Nassau grouper
- A study, published Jan. 6, has found that the population of Nassau grouper (Epinephelus striatus) around Little Cayman Island more than tripled between 2003 and 2015.
- The researchers attribute the rebound to a scientific monitoring effort by NGOs and universities as well as the Cayman Islands government response to the data.
- The government has closed the fishery and instituted size and catch limits to protect the critically endangered species.
Coal spill bedevils Indonesian beach more than a year later
- Coal from a barge that spilled onto a beach in Indonesia’s Aceh province in July 2018 still hasn’t been fully cleaned up.
- Lampuuk Beach, on the northern tip of Sumatra, is hosting a surfing championship this weekend, but participants and residents say that coal continues to litter and contaminate the site.
- The coal was destined for a power plant run by a cement producer, which had experienced an identical spill in 2016 at a nearby beach.
- While authorities have ordered the cement producer to clean up the site, the company says the barge operator should be held responsible.
Safer at sea: The unexpected benefit of traceability for small-scale fishers
- Consumers are demanding to know where the seafood they buy comes from to ensure catches are legal, sustainable and free from labor abuse.
- The technology to deliver that information, once out of reach for small-scale fishers, is becoming more accessible in places like the Philippines.
- Its adoption is not only increasing seafood traceability but also improving the safety of fishers while they’re out on the water.
- Fishers and their families, among the most vulnerable in the seafood supply chain, say they welcome the security and peace of mind the technology brings.
Ban on destructive fishing practice helps species recovery in Indonesian park
- In 2011, a destructive fishing practice known as muroami was banned in Karimunjawa National Park off Indonesia’s Java Island.
- In 2012-2013, the overall biomass of herbivorous fish species in the park had more than doubled from the 2006-2009 period, researchers have found.
- They attribute this recovery to the muroami ban and have called for it to be implemented in other marine parks across Indonesia.
Scientists emphasize disease control in booming aquaculture sector
- The World Organisation for Animal Health held a conference in Santiago, Chile, focused on aquatic animals
- Compared with land animals, little is known about diseases of aquatic animals.
- Yet experts are looking to aquaculture to support human food security in the coming years.
Madagascar: Opaque foreign fisheries deals leave empty nets at home
- Malagasy fishers blame shrimp trawlers that ply coastal waters for their declining catches.
- However, the bulk of industrial fishing in Madagascar’s waters takes place far from shore and out of view. It’s conducted by foreign fishing fleets working under agreements that critics say lack transparency.
- Conservationists argue that these foreign vessels are also depleting the country’s fish stocks and marine ecosystems.
- With negotiations to renew a fisheries deal with the European Union having flopped late last month and uncertainty lingering over an enormous and controversial fisheries deal with a Chinese company, much is at stake for Madagascar’s small-scale fishers.
Give it back to the gods: Reviving Māori tradition to protect marine life
- Ra’ui is an ancient Polynesian form of resource management in which traditional leaders close designated areas to the harvest of key species.
- While the power of ra’ui remains strong in the outer Cook Islands, where local tradition often trumps national decree, the system fell into disuse on the largest and most populous island of Rarotonga half a century ago.
- There, traditional leaders briefly and successfully revived the ra’ui system two decades ago, only for it to falter again in recent years.
- Today, traditional leaders in the Cook Islands are cautiously optimistic that the country’s 2017 decision to designate its entire marine territory as a mixed-use protected area will help reinvigorate ra’ui across Rarotonga.
Global fisheries deprive local communities of key nutrients, study finds
- New study shows that fish in tropical regions have higher concentrations of calcium, iron and zinc – critical for human health – than fish in colder waters.
- Fish already being caught off the shores of many nutritionally-vulnerable countries could easily meet needs for vital micronutrients for people living within 100 kilometres of the coast
- Fish – including small species traditionally landed, processed, and eaten locally – is instead being processed into fishmeal for export.
Paradise, polluted: Cook Islands tries to clean up its tourism sector
- Tourism accounts for almost 70 percent of the Cook Islands’ economy, but the industry is proving extremely damaging to its delicately balanced island ecosystem, and is contributing to islanders’ detachment from traditional ways of life.
- Now, though, some tourism players, activists and government officials are pushing the industry to change tack in hopes it can start to sustain the island’s people and culture while protecting its ecology, too.
- Tourism operators are being asked to live up to the sustainability street cred that the country’s 2017 decision to designate its entire exclusive economic zone as a multiple-use marine protected area has granted it on the international stage.
Will a massive marine protected area safeguard Cook Islands’ ocean?
- In 2017, the Cook Islands government passed the Marae Moana Act, which designated the country’s entire exclusive economic zone (EEZ) as a multiple-use marine protected area (MPA).
- Spanning almost 2 million square kilometers (772,000 square miles) — an area roughly the size of Mexico — the MPA is the biggest of its kind in the world.
- Now, as bureaucrats, NGOs and traditional leaders get to grips with implementing Marae Moana, many stakeholders are wondering what the act will mean in practice and whether it can meaningfully change the way the ocean is managed.
Rattled by sardine stock crash, India begins regulating its fisheries
- In India, fishing has transformed over the decades from a small-scale artisanal practice into an increasingly industrialized sector, and catches have grown apace.
- The industry has largely gone unregulated, and yields have slowed in the past decade, including an unexpected and disruptive crash in the sardine catch.
- In response, India’s coastal states and central government have begun to take measures to make fishing more sustainable.
- The latest, and potentially the most important move, is the creation of the first ministry for fisheries just last month.
Film that fish: Stereo-video speeds surveys of marine fish communities
- Researchers use underwater visual surveys to assess the sizes of fish in marine communities and their associated habitats, but diver-based data collection is time-consuming and requires expertise, and results may vary among different data collectors.
- A multinational research team recently published the first guide to help researchers using diver-operated stereo-video methods (stereo-DOVs) to standardize surveys of fish assemblages (species and their abundances) and their associated habitat.
- The video provides a permanent, shareable record of each survey transect, including the species and numbers of fish seen, while the stereo option allows researchers to measure fish using overlapping images.
- The guide provides information on appropriate equipment; designing a stereo‐DOV if needed; operating it during underwater studies; processing the video data after collection; and analyzing fish behavior, population features and habitat in the resulting video.
Ocean currents spin a web of interconnected fisheries around the world
- Most marine catches are made within a given country’s territorial waters, but the fish most likely originated in spawning grounds in another country’s jurisdiction, a new study shows.
- The modeling of catch, spawning and ocean current data shows that the dispersal of baby fish caught by ocean currents creates an interconnection between global marine fisheries.
- The finding highlights the need for greater international cooperation in protecting marine ecosystems everywhere, as an estimated $10 billion worth of fish spawn in one country and are caught in another every year.
Was Sierra Leone’s one-month fishing ban enough to replenish fish stocks?
- The Sierra Leone government closed the country’s waters to fishing by industrial vessels during the entire month of April to give flagging fish stocks a chance to rebuild. During that period artisanal fishers were allowed to fish.
- Both industrial and artisanal fishers appeared to support the closure, the first of its kind, amid declining catches and an influx of virtually unregulated foreign fishing vessels.
- Officials declared the closure a success, as part of Sierra Leone’s broader effort to formalize and gain regulatory control of its fisheries.
- However, outside experts have expressed doubt that the move would do much to improve the state of the country’s fisheries.
For artisanal fishers, fish fences are an easy, but problematic, option
- The widespread use of fish fences by fishing communities in tropical countries leads to extensive economic, social and environmental damage, a new study finds.
- The technique involves stringing a net along stakes typically set in an intertidal flat, where it traps fish as the tide goes out. But the practice results in the indiscriminate catch of juvenile fish, threatening the sustainability of fish stocks.
- In the area studied, in eastern Indonesia, the fences are also a source of social tension, where they’re the exclusive domain of the island-based ethnic group and denied to the seafaring Bajo community.
- The researchers have called for restrictions on the use of fish fences, but acknowledge that getting fishermen to start going out to sea to fish will be difficult, given the low risk and high convenience that fish fences afford.
Indonesia investigates mass shark deaths at captive-breeding facility
- An investigation is underway after 127 sharks died at a captive-breeding facility in a marine national park in Indonesia.
- Experts suspect poor water quality may have triggered the die-off.
- The breeding facility, operating since 1960 and a key attraction inside Karimunjawa National Park, was shut in June 2018 after a visitor swimming in one of the floating cages was bitten by a shark.
Indonesia’s tuna fisheries seek out sustainability certification
- One tuna fishing operation in Indonesia has been certified for its sustainable practices, and at least a dozen more are seeking similar certification to meet growing global demand for eco-labeled seafood.
- Indonesia is the world’s biggest producer of tuna, but its fisheries have long been plagued by poaching and destructive fishing practices.
- NGOs working with local fishing communities have called on the government to do more to support the drive toward sustainable fishing certification, given the costs of undergoing the necessary assessment and implementing operational changes.
Women in small-island states exposed to high levels of mercury: study
- Tests of hair samples from hundreds of women in small-island countries and territories found 75 percent had mercury levels high enough to cause fetal neurological damage.
- Nearly 60 percent of the women had mercury levels exceeding a threshold beyond which brain damage, IQ loss, and kidney and cardiovascular damage can occur.
- The report attributed the mercury pollution in fisheries in these regions to air emissions of the toxic heavy metal emanating from coal-fired power plants and artisanal gold mining.
- The researchers have called for a complete ban on the trade in and use of mercury, and urged a transition away from coal power to renewables.
Indonesia demands cleanup after coal spill pollutes beach
- A coal barge spilled 7,000 tonnes of the fossil fuel just off a beach in northern Sumatra on July 30.
- The coal was reportedly destined for a nearby cement plant run by a subsidiary of Swiss giant LafargeHolcim, but now blankets a popular beach.
- Local fishermen and activists say the coal has damaged coral and killed marine life, devastating the livelihoods of the community.
- Officials have called on the cement firm and barge operator to clean up the coal, while environmental experts are pushing for a lawsuit against the companies.
One-third of global fisheries operating at biologically unsustainable levels
- About 3.2 billion people around the world currently rely on fish for nearly 20 percent of their animal protein. That means that humans eat more than 150 million metric tons of fish every year — and as the global population increases by a couple billion over the next few decades, that number will surely rise.
- The fishing industry is eager to capitalize on this growth and boost profits, of course, but overfishing is already threatening the global supply of fish and there are plenty of reasons to be skeptical that this growth can and will be achieved sustainably.
- According to the Food and Agriculture Organization (FAO) of the United Nations’ latest report on the state of the world’s fisheries and aquaculture, however, that doesn’t mean we’re approaching “peak fish” — though it will require that fisheries management be strengthened and loss and waste reduced, while problems like climate change, illegal fishing, and pollution must also be dealt with.
Shark fisheries hunting dolphins, other marine mammals as bait: Study
- Global shark fisheries have for decades engaged in the deliberate catch of dolphins, seals and other marine mammals to use as bait for sharks, a new study has found.
- The researchers found the practice picked up when prices for shark fin, a prized delicacy in Chinese cuisine, went up from the late 1990s onward.
- The researchers have warned that the targeting of these species could hit unsustainable levels, and have called for more studies into the species in question as well as better enforcement of existing law protecting marine mammals.
Government subsidies serving to prop up destructive high-seas fishing: study
- More than half of fisheries on the world’s high seas would be running a loss without the billions of dollars in government subsidies that keep the ecologically destructive industry afloat, a recent study suggests.
- The researchers described the annual subsidies as being far in excess of the net economic benefit from fishing in these international waters.
- They called for greater transparency by governments and substantial reforms of high-seas fisheries in a bid to improve the management of the industry they labeled as ecologically and economically unsustainable.
Indonesia targets illegal fishing vessel owners under new bill
- Indonesia’s fisheries ministry has submitted to parliament a bill of amendments aimed at strengthening the 2009 Fisheries Act through more stringent provisions.
- These include recognizing, for the first time, the criminal culpability of the owners of vessels engaged in illegal fishing activities. Under the bill, these owners would face longer prison sentences and heavier fines than their crews.
- While legal experts and sustainable-fishing activists have welcomed the bill, concerns remain over the less-than-clear language of some of the provisions, which could open up loopholes.
- The government expects the bill to be passed this year, and says it will bring much-needed transparency to the fisheries industry.
Fishing gear poses the greatest danger to young great whites off the West Coast of the U.S.
- Fishing lines and nets pose the most significant threat to the survival of young white sharks in the waters off Mexico and southern California, according to a new study.
- A team of scientists used a relatively “untapped” but ubiquitous storehouse of data to develop a statistical model for the survival rates of juvenile white sharks.
- The researchers calculated that 63 percent of young white sharks living in this part of the Pacific survive annually, but that nearly half probably come in contact with gillnets set by commercial fishers.
- The findings point to best practices, such as barring gillnets from inshore “nurseries” and asking fishers to check their nets for trapped sharks more regularly, that could help protect great whites.
Scientists highlight 9 potentially new reef fish species off West Papua
- Scientists in Indonesia may have discovered nine new reef fish species in the waters off West Papua province.
- The discovery highlights the importance of protecting the region’s marine ecosystem for its vast and rich biodiversity.
- However, the researchers also found indications of blast fishing in the protected areas, and have called for sustainable management of the ecosystem.
Indonesia’s crackdown on illegal fishing is paying off, study finds
- Indonesia’s crackdown on illegal, unreported and unregulated fishing in its waters is paying off for domestic fisheries and fish recovery, according to a new study.
- But for Indonesia to continue to reap the benefits from its anti-IUU fishing policies, the country needs to ensure that domestic fishing efforts are also well-managed, the paper’s authors noted.
- Indonesia’s success in tackling illegal fishing provides an example that can be implemented in other countries plagued by overfishing by foreign vessels, the researchers concluded.
Under the sea: Life is the bubbles in newly described deep-reef zone
- Scientists have recently described a layer of the deep ocean zone as the “rariphotic,” calling it home to an array of unidentified reef fish and a refuge for species from shallower waters drive out of their coral habitats by warming waters.
- Nearly 4,500 fishes were observed representing 71 species, nearly half of them new species, the researchers reported.
- The scientists are calling for more exploration into deeper marine ecosystems to better understand the deep-reef ecosystems and the impact of changes taking place in shallower zones.
Study reveals the Pacific Garbage Patch is much heftier than thought — and it’s growing
- A recent survey of the Great Pacific Garbage Patch revealed that the aggregated plastic there weighs in at 79,000 metric tons (87,100 short tons).
- The plastic is floating across an area larger than Mongolia at 1.6 million square kilometers (618,000 square miles).
- Around 75 percent of the pieces that are larger than 5 centimeters (2 inches) in length, and old fishing nets make up a minimum of 46 percent of the total mass.
- The scientists calculated that 94 percent of the 1.8 trillion pieces of plastic in the patch are microplastics.
Analysis: U.S. call to drill off all coasts, economic and ecological folly?
- 90 billion barrels of recoverable oil, plus 327 trillion cubic feet of natural gas lie untapped offshore on the U.S. continental shelf. In January, the Trump administration ordered that the entire coast, in the Pacific, Atlantic, Gulf, and Arctic, be opened to drilling.
- Environmentalists and the coastal states fear oil spills that could devastate tourism. They also are concerned about the massive infrastructure (pipelines, terminals, refineries, pumping stations and more) that would be needed to support the industry.
- The executive branch has moved forward with efficiency to create a surge in U.S. oil and gas production: the Interior and Energy departments, and the Environmental Protection Agency have all worked to slash regulations and open additional lands and seas to oil and gas exploration, with the plan of achieving U.S. “energy dominance” around the globe.
- Most coastal states are resisting the federal oil and gas offshore drilling plan; Florida has already been exempted, while other states are likely to fight back with lawsuits. The irony is that a flood of new U.S. oil could glut the market and drive prices down, resulting in an economic disaster for the industry.
Gaza City residents’ water problems continue to compound
- Locked between increasingly-polluted seascape and the borders of one of the most tightly-controlled enclaves in the world, Gaza City residents say the water has become so polluted they can no longer go swimming.
- Situated at the borders of Egypt, Israel, and the Mediterranean Sea, Gaza’s 2 million residents fear that an ongoing electricity crisis has pushed their maritime ecosystem past the brink.
- 80 percent of Gaza’s Mediterranean Sea coastline is thought to be polluted and families who used to rely on it for livelihoods and leisure now fear its waters.
First vaquita ‘rescued’ in bid to save the porpoise from extinction
- A project to save a small, critically endangered porpoise called the vaquita in the Gulf of California succeeded in capturing a 6-month-old calf in mid-October.
- Veterinarians noticed signs of stress, so they made the decision to release it back into the wild, rather than keep it in a sea pen.
- The project’s leaders are heartened by the experience and hope to round up more vaquita to keep them safe from the still-present threat of gillnet entanglement in the northern Sea of Cortez.
The Philippines commits to science-anchored fishery policies
- The Philippines ranks 10th in the world in terms of its annual catch, and Filipinos consume 32.7 kilograms (72.1 pounds) of fish each year.
- At the same time, 70 percent of the Philippines’ fish populations are overfished.
- The country is now set to work with the Environmental Defense Fund to bring data analysis and science into fisheries decisions by 2022.
‘SALT’ alliance aims to tackle illegal fishing on a global scale
- The Seafood Alliance for Legality and Traceability (SALT) alliance announced today at the Our Ocean conference in Malta aims to bring together representatives from seafood companies and seafood-producing and -consuming countries to decrease illegality in the fishing sector.
- Scientists reported that between 11 million and 26 million metric tons (12.1 million and 28.7 million tons) of the worldwide catch is illegal or unreported, costing as much as $23.5 billion a year.
- A year-long process headed by the NGO FishWise that will seek input from a variety of stakeholders begins this month.
Modern Fish Act: boon to recreational fishing or risk to U.S. fishery?
- The Magnuson-Stevens Fishery Conservation and Management Act sets strict, scientifically adjusted, annual catch limits on U.S. commercial, charter and recreational fisheries in order to sustain saltwater fish stocks, and is seen as a model of fishery management globally.
- The Modern Fish Act (MFA), a bill introduced in the U.S. House in April, would do away with limits on recreational fishermen, who argue they have no impact on fishery stocks. Environmentalists, however, say the MFA introduces legal loopholes that would allow for uncontrolled fishing at potentially unsustainable levels that could cause stocks to crash.
- Critics also say that the MFA muddies the waters between federal and state management, and allows political and economic considerations to override science in management decisions. The bill is still moving through Congress, and its chances for passage are presently unknown.
- The Trump administration has already made moves to undermine scientifically arrived at recreational fishing limits. Its Commerce Department overruled a NOAA limit on the red snapper season in the Gulf of Mexico, a ruling experts say could delay the fishery’s recovery.
New atlas bolsters global perspective of fisheries – book review
- The Global Atlas of Marine Fisheries draws on 10 years of fisheries data.
- More than 350 scientists around the world were involved in an effort to provide a more complete look at global fisheries.
- The team reconstructed fisheries datasets going back to 1950 to fill in gaps that exist in Food and Agriculture Organization’s State of the World’s Fisheries and Aquaculture.
Lake Maracaibo: an oil development sacrifice zone dying from neglect
- Venezuela’s Lake Maracaibo is a Caribbean estuary that for many years supported a strong commercial fishery. But over the past century the vast briny lake’s underlying oil deposits became a cash cow for the oil-dependent Latin American nation.
- Today, hundreds of working and abandoned oil wells mar the surface of Lake Maracaibo, and more than 25,000 kilometers of crumbling pipeline crisscross the bottom of the estuary ecosystem. Spills have increased since 2009 when the 76 companies that replaced and repaired the pipelines were taken off the job by the government.
- According to a report by state-owned oil company Petroleos de Venezuela SA (PDVSA), 15 “minor” spills — leaking about eight barrels of oil every day, nearly 3,000 barrels per year — are flowing from the poorly maintained pipelines into the estuary.
- Fishermen say that many commercial species have declined or disappeared completely since the Venezuelan economy hit hard times and oil cleanups have largely ceased in Lake Maracaibo — which seems to have become an oil infrastructure sacrifice zone.
