Indigenous knowledge helps reveal the ties between reefs and mangroves
- A scientific collaboration between Australian scientists and First Nations Bardi Jawi rangers and elders has highlighted how fish species rely on the connectivity of reef and mangrove ecosystems.
- The study found that culturally important fish species, which form part of traditional fishery practices in the Kimberley region of northwestern Australia, migrated between the two ecosystems more than other species.
- The collaboration enabled Western scientists to draw on millennia of traditional ecological knowledge in carrying out the study and interpreting its findings.
- While most of the findings were already part of traditional ecological knowledge, rangers say they learned how certain species may not be able to survive if either reefs or mangroves were threatened by climate change and environmental impacts.

Marine conservation collides with mining in Indonesia’s biodiversity-rich Moramo Bay
- Pressure on a protected marine area in Indonesia’s Southeast Sulawesi province is growing as conservation efforts intersect with mining activity.
- Moramo Bay is part of the Coral Triangle, one of the world’s richest marine biodiversity regions, and provides habitat for humphead wrasse and other protected species.
- Researchers and officials say the health of its coral reefs and marine life is increasingly under scrutiny as development expands around the conservation area.

South Korea’s ‘sea women’ seek justice after marine habitat devastated by harbor work
- A community of hanyeo, South Korea’s free-diving women fishers, accuse a harbor project in their village of devastating the local marine habitat they’ve depended on for decades for their livelihoods.
- The women are demanding compensation from construction giant Ssangyong, taking their fight to Seoul after the loss of their traditional fishing grounds.
- While they are not ruling out a lawsuit against the company or the government, they face a costly, years-long legal battle requiring scientific evidence linking the construction activity to the habitat’s destruction.
- With many of the haenyeo now in their 70s and 80s, time is not on their side and some say a settlement on offer from the company amounts to little — slightly more than enough to cover the costs of their protest trip to Seoul.

Global sea surface temperatures reach a record high, again
Global sea surface temperatures have reached a record high, raising serious concerns for global Earth systems, according to new data released by the European Union’s Copernicus Climate Change Service (C3S). On Aug. 22, the daily global average sea surface temperature, outside polar regions, reached 21.1° Celsius (69.98° Fahrenheit), exceeding the previous record set in March […]
Blast fishing destroys reefs. Underwater microphones can help detect it
- Once home to a pristine and vibrant network of coral reefs, the Spermonde Archipelago off the coast of South Sulawesi in Indonesia has had its coral decimated by the illegal practice of blast fishing, in which improvised explosives are tossed into the sea to kill and stun fish en masse.
- A new study harnesses acoustic data to produce what is likely the first rigorous estimate of the frequency and intensity of bomb fishing in the archipelago.
- Using low-cost microphones and an easy-to-run algorithm, the researchers detected more than 3,500 so-called fish bombs going off in their study area within the archipelago — an average of 23 blasts a day, or almost one every hour.
- The scientists believe their approach could help communities and NGOs around the world design targeted interventions to combat the practice, which can devastate not only reefs but the broader marine ecosystems.

Scientists discover 149 new deep-sea species at remote Indian Ocean seamounts
- A new study details a deep-sea expedition near the remote Christmas and Cocos islands, where researchers visited unexplored seamounts and identified 149 previously unknown marine species, including black corals, sea worms, sea cucumbers and a variety of fish.
- At a site they dubbed “The Shark Tooth Graveyard,” researchers discovered around 1,000 shark teeth, covering more than 22 million years of evolution.
- Researchers from institutions in Australia, New Zealand, Canada and the U.S. surveyed the seafloor down to 5,431 meters (17,818 feet), where conditions are cold, dark and high-pressure with limited food options for benthic species.
- Deep-sea research is notoriously challenging, but scientists stress the importance of exploring these ecosystems as they face growing threats from warming oceans, pollution, overfishing and deep-sea mining.

El Niño is disrupting the Pacific’s marine food web from the bottom up
As the 2026 El Niño strengthens in the equatorial Pacific, satellites are capturing the first major signs of disruption to the marine food web. According to by NASA’s Earth Observatory observations, satellite measurements show a substantial drop in surface concentrations of chlorophyll across the Central Pacific compared with neutral conditions in June 2025. Chlorophyll is […]
Local knowledge guides rediscovery of spinach pipefish, not seen in four decades
- Scientists have rediscovered spinach pipefish, a freshwater species endemic to Papua New Guinea’s Sepik River, not seen in nearly 40 years.
- The discovery came during a two-week survey led by local scientists and community members. Local fisherwoman Helen Asu netted two spinach pipefish, which scientists sent to experts for confirmation of the taxonomy.
- Scientists say the rediscovery offers hope that populations of the little-known, elusive fish still survive and provides an opportunity to understand more about its life cycle, habitat and ecology.
- The discovery highlights the importance of combining local knowledge with scientific research.

Antarctic krill fishery closes months early amid increasing fishing pressure
- The krill fishery in the Southern Ocean has closed more than three months early after reaching its annual catch limit of 620,000 metric tons — a precautionary quota established to prevent overfishing.
- Krill forms the foundation of the Antarctic food web, with penguins, whales, seals, fish, squid and other animals depending on the tiny shrimp-like crustacean.
- The early closure of the fishery is linked to the growth of the krill-targeting fleet, as well as to what some scientists call an “unprecedented” concentration of fishing activities in areas where krill is most abundant.
- Scientists are raising concerns about the combined impacts of overfishing and climate change on both krill and the Antarctic and Southern Ocean wildlife it nourishes.

Reconnecting the skies: Linking flyways for migratory seabirds across continents
- Seabirds are the most threatened group of birds, with more than 30% at risk of extinction. Migratory seabirds are especially vulnerable.
- Researchers have described six marine flyways used by migratory pelagic seabirds, aerial corridors that cross the national waters of 56 countries; the high seas are used by at least 151 species.
- In March, the U.N. Convention on Migratory Species adopted a resolution on marine flyways, creating a structure for international cooperation on protections.
- Researchers are using seabird tracking data to identify key sites along marine flyways that need protection or mitigation measures against threats.

Indigenous fishers rethink shark hunting & protect species on Colombia’s coast
- In the Colombian department of La Guajira, at South America’s northernmost tip, Indigenous Wayuu fishers from the community of Punta Gallinas are working with marine biologists to conserve and document shark populations.
- Despite a 2021 law banning targeted shark and ray fishing in Colombia, the meat remains a vital protein source in one of the country’s most remote and food-insecure regions.
- Colombian shark conservation initiative Proyecto Puyuii is working with Wayuu fishers to record shark species in the understudied waters of La Guajira, implementing sustainability measures such as larger-mesh nets, safe release techniques and avoiding longlines.
- With sustainable tourism touted as a potential economic alternative to shark fishing, some fishers argue that compensation will need to be offered before they can afford to stop.

Philippine Supreme Court rules monitoring commercial fishing vessels is unconstitutional
- The Philippine Supreme Court struck down a regulation requiring commercial fishing vessels to continuously transmit their locations and submit electronic catch reports.
- The requirement was partially implemented before being suspended in 2022 during a court challenge, with devices installed on about 52% of targeted vessels.
- Small-scale fishers and scientists warn reduced oversight could increase commercial incursions into coastal waters where many fish stocks are already overexploited.
- Following the high court’s decision, the country’s Bureau of Fisheries and Aquatic Resources filed a motion for reconsideration, a procedural remedy that allows a party to ask the Supreme Court to review its ruling before it becomes final.

Mobile queen conch hatcheries strive to help the species, engage Caribbean communities
- International demand for queen conch meat and shells has led to severe overharvesting, while habitat degradation, pollution and warming waters add further threats.
- In a bid to slow the decline of the queen conch, researchers are partnering with local conservation organizations across the Caribbean to establish a network of mobile hatcheries aimed at protecting the giant marine snail through its vulnerable early life stages.
- The goal is not only to nurture developing conch, but to create community spaces where local people can learn about the queen conch life cycle and participate in restoration efforts.
- However, some researchers have doubts about whether aquaculture alone can restore wild conch fisheries.

Aceh’s community fishers struggle to preserve tradition amid blooms of plastic pollution
- Coastal communities in Indonesia’s Aceh province have practiced community fish trawling since the time of the Aceh Sultanate, but the tradition today exists in only a handful of communities across the semiautonomous province.
- The customary panglima laot, a customary fishery lead, at one beach in the Aceh capital Banda Aceh, told Mongabay Indonesia that the customary rules included environmental protections such as requirements not to take threatened species.
- However, this traditional fishing practice is under threat due to the increasing burden of plastic and other household waste accumulating in nearshore waters and along beaches.
- For many, the time and cost required to patch holes in giant fishing nets can make the cost of doing business unviable, leading some fishers to abandon the tradition for jobs elsewhere.

South Africa’s top court blocks Shell oil exploration off country’s Wild Coast
In a landmark judgment on Aug. 14, South Africa’s Constitutional Court set aside exploration rights held by oil giant Shell and Impact Africa, a South African oil and gas company. The ruling prevents the companies from exploring for fossil fuels off South Africa’s Wild Coast. The case was brought by Wild Coast communities and environmental […]
Sand mining plans spark opposition from fishers in Indonesia’s Riau Islands
- Plans to mine marine sand off Indonesia’s Numbing Island have sparked opposition from fishers, environmental groups, and some lawmakers who warn of damage to fishing grounds and marine tourism.
- Although the government describes the project as marine sediment management and no company has begun operations, the proposal has divided local communities over the promised compensation.
- Critics warn the dredging could increase water turbidity, damage coral reefs, alter coastal currents, and weaken natural coastal defenses.
- The dispute has also raised legal and geopolitical concerns, with researchers arguing the Riau Islands’ strategic location makes the environmental risks a national security matter.

Illegal mining threatens Ghana’s first marine protected area
- Illegal gold mining in Ghana’s Greater Cape Three Points Forest Reserve threatens vulnerable and endangered species in the protected forest, say conservationists.
- Sediment and toxic chemicals from the mining also threaten the adjacent waters of a newly declared marine protected area just offshore.
- Conservation NGOs want the government to act against illegal miners, including establishing permanent camps in the forest to protect a wider area.

Cambodia’s banned sand trade with Singapore appears to be back
- Cambodia appears to have resumed exporting sand to Singapore, despite a 2017 national ban, with Koh Kong provincial authorities saying a new dredging operation has been licensed.
- Mongabay traced at least four bulk carriers from Koh Kong to Singapore’s Tuas Port, where the site of a massive land reclamation project.
- The dredging is taking place within protected area boundaries and could affect riverbanks, fisheries and wildlife, as well as a major downstream mangrove forest.
- Environmental activists say they hope to draw attention to the renewed sand trade, but Cambodia’s shrinking civic space and restrictions on civil society groups have made standing up to environmental violations increasingly difficult.

Gabon ends fisheries partnership agreement with EU
Gabon has ended its 19-year fisheries partnership with the European Union, which allowed EU industrial vessels to target tuna in Gabonese waters in exchange for payment, arguing the agreement no longer serves the country’s economic interests. The decision follows a June 2025 Council of Ministers meeting at which the government announced it would seek to […]
Decades after bottom trawling, Chilean seamounts remain degraded
- A new study found seamounts in Chile’s Juan Fernández Archipelago remained degraded 25 years after bottom trawling took place there, while an ecologically similar seamount outside of the archipelago, where no bottom trawling had been recorded, continued to support deep-sea habitats, including coral and sponge communities.
- The researchers also found that the degraded seamounts in the archipelago had become inundated with sea urchins, which they hypothesized could be preventing the recovery and regrowth of coral communities.
- While the lead author of the study said the research points to the destructiveness of bottom trawling, an outside expert said bottom trawling is not as destructive in some other marine environments, such as sandy, naturally dynamic seabed habitats.
- While the study’s authors call for protection of these surveyed seamounts, experts acknowledge that protection may not be enough if destruction has already occurred.

How social media and parrotfish poop are protecting the Maldives
- Parrotfish play a vital role in reef ecosystems by producing sand from consumed coral and maintaining healthy reefs by grazing algae; in doing so they support the sediment accretion processes that help low-lying atolls naturally grow and adapt to rising sea levels.
- A grassroots social media campaign in the Maldives raised awareness about the ecological importance of parrotfish, helping build widespread public support for their conservation after the species began proliferating in local fish markets during the COVID-19 pandemic.
- Public backing from the #FishForTomorrow campaign led the Maldivian government to ban the catch of all parrotfish species in 2020, making the Maldives one of the first countries to enact national protections based largely on community advocacy.
- Building on this success, the NGO Maldives Resilient Reefs is expanding conservation efforts through sustainable fishing partnerships, seagrass protection and a nationwide initiative to protect 30% of the country’s marine habitats by 2030.

Documentary captures impacts of diamond mining along South Africa’s West Coast
- A documentary explores the legacy of mining along South Africa West Coast and its impacts on coastal ecosystems and the local population.
- The West Coast, an area stretching 450 kilometers up to the Namibian border, has historically been a hotspot for diamond mining.
- Out of Mined features the voices of the Indigenous Nama peoples, fishing communities and conservationists who live with the long-term impacts of the extractive industries.
- The region is now facing a new wave of mining applications, mostly targeting heavy minerals.

Wind farms join bottom trawlers and oil rigs in a protected North Sea sandbank
- Dogger Bank is a vast, shallow sandbank in the North Sea that was once among the most productive marine nurseries in Europe, prompting experts to call it the ecological heart of the North Sea.
- While much of Dogger Bank has been protected for its unique seabed habitat, destructive industrial activities like oil and gas extraction as well as fishing practices like bottom trawling have continued, even in the protected zones.
- Now, conservationists have notched a win with a recent court ruling that curtails bottom trawling in Dogger Bank.
- However, they say the threats continue, notably in the form of major wind farm developments rising in a protected area.

First Nations lead the return of salmon to Canada’s Upper Columbia River
- First Nations in British Columbia, western Canada, are working to restore salmon to the Upper Columbia Basin and leading ceremonial salmon fry releases to reestablish connections between salmon and salmon people.
- The Columbia River was once one of the greatest salmon-bearing rivers in North America, but the construction of the Grand Coulee Dam, built without fish passage mechanisms, blocked salmon from a significant portion of the river’s length.
- The loss of salmon has profoundly affected Indigenous nations and tribes, with a loss of food sovereignty and cultural connections.
- The Bringing the Salmon Home initiative, led by the Secwépemc, Syilx-Okanagan and Ktunaxa nations, in partnership with the governments of British Columbia and Canada, is advancing salmon reintroduction to the Upper Columbia Basin, with technical studies showing reintroduction is feasible.

Fatal WWII bomb blast in Indonesia was a result of illegal fishing activity, police say
- At least seven people were killed on May 31 when a World War II bomb exploded in Fandoi village on Indonesia’s Biak Island.
- Interviews with officials indicate the explosion occurred while an unexploded wartime ordnance was being dismantled to recover explosives for illegal blast fishing.
- The HALO Trust estimates that unexploded bombs and ammunition have killed or injured around 25,000 people in neighboring Papua New Guinea since the end of the World War II, reflecting the region’s enduring wartime legacy.
- A casualty estimate for the Indonesian territory of the New Guinea archipelago is unclear.

Fishers fight for solutions as Brazil lists tambaqui as threatened
- One of the most cooked fish in the Brazilian Amazon, the tambaqui was included in the official national list of threatened species, triggering fear of losses from Amazon small-scale fishers who depend on the species for their livelihood.
- The tambaqui was classified as vulnerable due to projections of a 43.4% overall population decline over three generations as it’s targeted by intense fishing.
- Starting at the end of October, its fishing could be prohibited in Brazil if a recovery plan isn’t implemented, according to the Ministry of Environment and Climate Change.
- The gray triggerfish was also included in the list of 490 fish and invertebrate threatened fauna, triggering reactions from artisanal fishers and the fishing industry.

‘The shape of the land will change:’ South African villages resist heavy sands mine
- Communities in South Africa’s Eastern Cape are opposing a proposed heavy mineral sands mine that a South African company wants permission to operate day and night for 30 years on their communal land.
- They say the land targeted for mining is far from unused, supporting more than a 1,000 cattle, traditional medicine gathering, tourism and facilitates access to the coast and fishing.
- The villagers say that if the mine goes ahead, it will damage livelihoods, ancestral graves, biodiversity and water resources.
- The planned mine could also impact their long-running campaign to acquire commercial seaweed harvesting permits and an existing small-scale sand mining business run by a village committee.

Finning the High Seas
This investigative series uncovered a massive illegal shark-finning scheme and widespread labor abuses across the fleet of Dalian Ocean Fishing (DOF), a major Chinese tuna company with dozens of boats operating in international waters. Reporters tracked down and interviewed some two dozen Indonesian deckhands who worked aboard the company’s vessels, documenting their experiences with excessive […]
New treaty promises safer conditions for Indonesia’s fishing crews
- Indonesia has ratified the ILO Work in Fishing Convention (ILO 188), committing to stronger protections for fishing crews, including safer working conditions, fairer pay and better access to health care.
- Labor groups say the convention could close long-standing legal gaps that have left many domestic fishing workers vulnerable to poor conditions and weak oversight.
- Experts say stronger labor standards could also help curb illegal fishing and boost the credibility of Indonesian seafood exports in markets with strict sustainability requirements.
- The biggest challenge now is implementation, with the government facing a year to update regulations and improve enforcement, training, and support for the fishing industry.

One scientist’s mission to save Ghana’s disappearing guitarfish
- Fishers from Ghana travel the length of the West African coastline to find the richest fishing grounds, but the availability of this vital source of protein is under threat from a number of sources.
- Declining catches of bony fish like tuna and mackerel have put elasmobranch populations — sharks and rays — under increasing pressure by fishers, who seek them not just to supply local markets for their meat, but to meet lucrative demand for their fins from Asia.
- Sawfish and wedgefish species have now been fished to local extinction in Ghana, and marine biologist Issah Seidu warns guitarfish will be next.
- Earlier this year, Seidu was the recipient of a Whitley Award, which will support the work of his NGO alongside Ghanaian fishing communities to research and protect guitarfish.

How saline drinking water raises preeclampsia risks in coastal Bangladesh (commentary)
- Climate change and rising sea levels are driving salt water intrusion into drinking water sources in coastal Bangladesh, which research links to an increased risk of preeclampsia, a leading cause of maternal mortality.
- Rural communities lack adequate freshwater infrastructure, which means pregnant women are often forced to consume saline water, making them particularly vulnerable to the life-threatening effects of excessive sodium intake.
- To address this hidden health crisis and prevent further maternal deaths, Bangladesh’s government and partner organizations must take urgent action by subsidizing household rainwater harvesting tanks for the most vulnerable coastal families.

What happened to the vessels Panama busted in 2025 for fishing in its flagship MPA?
- In January 2025, Panama’s government announced it had caught more than a dozen vessels fishing illegally inside the country’s flagship marine protected area, declaring it the largest such enforcement operation in the country’s history. Yet the government has released little information about the case over the past year and a half.
- To find out what happened, Mongabay sought information from Panamanian government agencies and reviewed government files that a local nonprofit obtained in freedom of information requests. Much of the information in this article, including about the number and nature of the vessels involved and the status of legal proceedings, hasn’t previously been reported.
- Two government agencies have issued fines against many of the vessel owners, though certain cases have been dismissed and the fines in other cases were reduced upon appeal. The status of criminal proceedings led by the public prosecutor’s office, a third government authority, isn’t known.
- The fishers involved protested the fines on multiple grounds; for one, they’ve said they weren’t in fact fishing. Meanwhile, a representative of the Panama-based nonprofit said the government hadn’t been strict enough in enforcing the MPA’s rules and hasn’t conducted the cases with full transparency. The agencies have rejected the criticisms.

Activists allege Cambodia has resumed sea sand exports to Singapore
- An environmental group in Cambodia alleges that sea sand exports to Singapore have quietly resumed despite a 2017 government ban, citing new footage of dredging operations and cargo vessels bound for the city-state.
- The allegations by Mother Nature Cambodia revive long-standing concerns over sand mining in Koh Kong province, where dredging has been linked to environmental damage and declining fisheries, and where a previous export scandal prompted the 2017 ban.
- Cambodia’s minister of mines defended sand mining as important for navigation and construction, while acknowledging environmental concerns, but did not address claims that exports to Singapore have resumed.
- The dispute comes as Mother Nature Cambodia continues to face pressure from the government, with several of its members imprisoned on charges widely viewed as retaliation for exposing environmental abuses.

Melanesian nations announce intention to create massive ocean reserve corridor
- Solomon Islands is the latest Pacific island nation to sign on to a new network of marine protected areas (MPAs) known as the Melanesian Ocean Corridor of Reserves, or MOCOR, which was announced by Papua New Guinea, Vanuatu and Fiji at the first Melanesian Ocean Summit in May.
- Located in the southwestern Pacific, Melanesia is a hotspot for marine biodiversity and the discovery of new species.
- While large marine corridors can be more effective than isolated MPAs, researchers caution that robust management and enforcement are necessary to prevent them from becoming so-called “paper parks.”
- Details about MOCOR’s size, configuration, precise location, governance, enforcement mechanisms and community consultation processes are scarce.

Why Africa should link nutritional data with fisheries management (commentary)
- The Our Ocean Conference in Kenya last month put Africa’s ocean future in the global spotlight, but the real test now is whether new commitments help countries build the systems needed to manage aquatic foods for people and not just for production, trade and conservation, a new op-ed argues.
- Fisheries ministries count landings, and health ministries count nutritional deficiencies, but rarely do the two talk to each other — a problem which can be addressed when the right data is gathered and communicated.
- “If Africa can pivot to managing fisheries not only for how much is produced, but for what the catch means for its people’s nutrition, the next generation of fisheries management will be able to harness its oceans for greater social impact and inclusive development,” writes Essam Yassin, director general of research organization WorldFish.

Fossil fuel-based mega projects displace locals in Bangladesh, pushing youth out
- The Bangladesh government has adopted a master plan to develop Maheshkhali sub-district through three industrial zones: An energy hub with 13 gigawatts of LNG and coal power plants, a deep-sea port with container and multipurpose terminals, and a special economic zone.
- The development requires about 37,000 hectares of land across Maheshkhali and Matarbari coastal areas, potentially displacing more than 770,000 residents.
- A coal power plant and deep-sea terminal have already displaced 20,000 people by acquiring 2,820 acres of land used for salt production, fish farming and shrimp cultivation.
- The coal power plant and deep-sea terminal have affected more than 90,000 people, leaving many without livelihoods and pushing some to risk illegal migration to East Asia for work.

A marine protected area can ban fishing boats. It cannot stop drifting gear
- Drifting fish aggregating devices, or dFADs, are widely used by tuna fleets to gather and catch fish, but they can drift into marine protected areas without vessels crossing the boundary.
- A new Science Advances study found that dFADs have likely interacted with 53% of the global MPA network by area and stranded in 174 protected areas, including sites that harbor at least 490 at-risk species.
- The problem exposes a weakness in ocean protection: MPAs can regulate fishing boats inside their boundaries, but they are less equipped to manage mobile industrial gear that crosses those boundaries, sinks, breaks apart, or washes ashore.
- The costs often fall on MPA managers, island communities, and conservation groups, making dFADs a test of whether fishing governance can assign responsibility before protected areas become cleanup sites for other people’s gear.

 Seeking swordfish, catching dolphins and whales: EU pushes to rein in driftnets
- Environmental groups continue to allege widespread illegal use of driftnets in the Mediterranean Sea.
- The use of driftnets — fishing nets, sometimes kilometers long, that drift with the ocean currents — is prohibited to catch large pelagic species like swordfish.
- Highlighting that current measures lack adequate definitions and enforcement provisions, the European Union presented a proposal to strengthen international restrictions on driftnet fishing at the International Commission for the Conservation of Atlantic Tunas technical meeting in June.
- Morocco, one of the countries most criticized for the use of illegal large driftnets, has emerged as a strong supporter of the proposal.

Illegal fishing takes a toll on Australia’s sea cucumbers
- Researchers blame an increase in illegal fishing for the decline of sea cucumbers in a remote Australian marine park and say many other reefs in the country have also been affected.
- The Australian government has launched an operation to crack down on illegal fishing in the country’s Northern Territory where the problem is acute, including for high-value sea cucumbers.
- But as long as the market for sea cucumbers remains strong in China and other East Asian countries, experts say, wild populations of this slow-growing animal could collapse and put the health of reef systems at risk in Australia and beyond.

Cabo Verde program and its fishers have been protecting the sea for 10 years
- In Cabo Verde, 190 fishers from seven of the archipelago’s 10 islands volunteer with the Guardians of the Sea program, reporting illegal practices and sightings of marine megafauna as they go about their daily fishing work.
- Their presence at sea acts as a strong deterrent against illegal activities and raises awareness among other fishers about the importance of long-term, sustainable marine management, according to a program co-founder.
- Fishers have always been a pillar of Cabo Verde’s economy and identity. The country hosts a fleet of approximately 1,535 vessels, ranging from artisanal to semi-industrial, and the sector provides a livelihood for coastal families.

‘The only possible transition is a just transition’: Interview with WEF’s Clemence Schmid
- Kenya formally launched the National Plastic Action Partnership (NPAP) in collaboration with the Global Plastic Action Partnership (GPAP), an initiative of the World Economic Forum, at the Our Ocean conference held in Mombasa.
- Plastic pollution is a pressing threat to Kenya’s marine ecosystems, fisheries and coastal livelihoods, driven by poor or non-existent waste management on land, along the coast and at sea.
- The initiative seeks to accelerate the transition to a circular plastics economy, which aims to reduce plastic pollution, valorize materials traditionally considered ‘waste’ and generate economic opportunities in the process.
- Mongabay spoke to Clemence Schmid, Director, Global Plastic Action Partnership (GPAP), on the sidelines of the Mombasa conference to understand what the collaborative effort is trying to achieve in Kenya.

Sightings off Southern Africa suggest blue and fin whales may be rebounding
Sightings of blue whales and fin whales off Southern Africa’s Atlantic coast have increased in recent years, according to a newly published study. This could signal recovery of the marine mammals after being virtually eliminated from the area by commercial whaling in the 20th century, the study authors say. Scientists estimate around 350,000 Antarctic blue […]
Declining carp fishes in Bangladesh’s Kaptai Lake leave small-scale fishers struggling
- Kaptai Lake is one of Bangladesh’s largest inland fish hubs, supporting the livelihoods of more than 27,000 registered fishers in the Chittagong Hill Tracts.
- Over the past several years, catches of high value carp fishes have declined sharply, forcing many small-scale fishers to abandon or supplement the ancestral profession.
- Researchers said carp species depend on specific spawning conditions including suitable breeding grounds. But the lake’s major breeding areas have been degraded, while overharvesting has further reduced the chances of natural recovery.
- Experts warn that without restoring breeding grounds, increasing carp fry stocking and improving fisheries management, the decline could continue, which would deepen economic pressure on small-scale fishers.

Indonesia’s ratification of fishing labor reforms will also boost conservation (commentary)
- Indonesia’s formal ratification of the ILO Work in Fishing Convention is a historic milestone for workers and will boost the sustainability of the fishing industry, the writer argues.
- Such reforms require a broad coalition beyond traditional labor actors and must include fisheries authorities, fishing companies, fishers’ organizations and conservation groups.
- “Fishers working under safer and fairer conditions are more likely to engage in responsible fishing practices and support conservation measures,” the author writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Recent discoveries of ‘lost’ Mekong giant salmon carp renews hope for the fish
A large fish once feared extinct in Cambodia has been recorded in the country’s waters for the fourth time since 2020, renewing hope for the species. The Mekong giant salmon carp (Aaptosyax grypus), a critically endangered large-sized freshwater fish, was formally described from the Mekong River in 1991. Over the next 14 years, there had […]
Aquatic animal and terrestrial meat trades now almost on par, FAO report finds
- The FAO recently released its State of World Fisheries and Aquaculture (SOFIA) report, a biennial collection of data that policymakers, scientists and civil society groups rely on.
- Global fisheries and aquaculture production, including algae as well as animal products, reached a record 235 million metric tons in 2024, with farmed aquatic animal production surpassing 100 million metric tons annually for the first time. This brings the total aquatic animal product trade close to that of terrestrial meat.
- The report, which covers around 70% of global fisheries, found that sustainably fished stocks fell by 2.1% to a new low of 62.4%.
- The report projects continued growth in aquatic animal production from both fisheries and aquaculture, but warns that achieving it sustainably and equitably will require greater investment, effective governance and continued innovation.

Women patrol Tanzania’s Pemba waters in a community-led push to protect the sea
- More than 1.8 million people live in Zanzibar, the semi-autonomous archipelago that united with Tanganyika in 1964 to form present-day Tanzania.
- Of Zanzibar’s population, roughly 550,000 people live on Pemba Island, one of its two main islands, where many households depend directly on the surrounding marine ecosystem for food, income, and livelihoods.
- Across the island, a community-led approach to marine resource management is taking root. Local communities are organized through Shehia Fisheries Committees and Collaborative Management Groups, which develop and implement rules governing the use of marine resources, including fisheries and locally managed conservation areas.
- Enforcing those rules, however, is not always straightforward. Community patrol teams often lack the legal authority needed to take action against offenders. In a largely Muslim society where marine patrols have traditionally been dominated by men, women are increasingly joining these teams to help monitor fishing activities and encourage compliance.

India’s fishers confront homegrown ‘ghost gear’ problem
- Across India’s west coast, fishers often abandon or discard their damaged gear at sea after seabed snags, mounting economic pressures, and increasingly crowded near-shore waters make recovery difficult, creating a constant stream of “ghost gear” into the Arabian Sea.
- Once lost, fishing gear continues to function, whether it drifts through the water column or settles on the seabed, trapping marine life or entangling marine habitat.
- Incentive schemes, retrieval efforts, recycling initiatives and other efforts to reduce harm show promise in some places in India. But experts say they tend to remain piecemeal and face common challenges such as a lack of recycling infrastructure and dependence on short-term funding.
- Many experts say the key to addressing India’s ghost gear problem lies in moving from ad hoc initiatives to institutionalized systems that intervene across the gear’s lifecycle, from design and use to end-of-life disposal.

A trailblazing Ugandan championing women in African fisheries: Q&A with Lovin Kobusingye
- In fishing communities along Africa’s coast, women are often the backbone of household economies. They process and sell fish, support households and pay school fees, often while facing significant economic and social challenges.
- Hotels, ports and other developments are reshaping many African coastlines. While they can bring jobs and investment, some women working in fisheries say they are also being pushed away from traditional landing sites and areas they have depended on for generations.
- At a recent gathering of marine organizations in Kenya, one woman stood before the audience to share the realities faced by women fishers, fish traders and others working across the fisheries value chain.
- Uganda’s Lovin Kobusingye knows those realities well. Having overcome numerous obstacles of her own to become a successful entrepreneur, she now advocates on behalf of millions of women working across Africa’s fisheries value chain, many of them women whose contributions to fisheries remain largely unseen and undervalued.

Three years after Cyclone Freddy, farms remain under water in Malawi’s Elephant Marsh
- Hundreds of thousands of people depend on Malawi’s Elephant Marsh for their livelihoods.
- Despite the name, there are no longer elephants in these wetlands, whose boundaries expand and contract with seasonal rains, but they provide habitat for hippos, crocodiles, fish and more than 100 waterbird species as well as thousands of farming and fishing households.
- The water from floods caused by 2023’s Cyclone Freddy never receded from large parts of the marsh, and this has displaced more than 1,000 farming households.
- Ongoing changes to the landscape upstream and in the marsh itself have destabilized the wetlands’ ability to absorb seasonal flooding. Increasingly frequent storms like Freddy are a further challenge to the ecosystem’s functioning.

Asia’s shark and ray hotspots remain poorly protected, study finds
- A new regional assessment has identified 122 important shark and ray areas (ISRAs) across Asia, spanning more than 1 million square kilometers (386,102 square miles) and supporting 121 species, many of them threatened with extinction.
- Despite their ecological importance, only 5.4% of these habitats overlap with existing marine protected areas with only 2.8% falling within fully protected no-take zones, highlighting major conservation gaps.
- Sri Lanka has five identified ISRAs, home to nine species with eight of them threatened with extinction, but only Pigeon Island in the island’s east is formally protected, with most areas still functioning as active fishing grounds.
- The new study underscores an urgent need to move from mapping to management, using ISRAs to guide marine spatial planning, fisheries regulation and habitat protection ahead of global 30×30 ocean targets.

In Kenya’s Mida Creek, fishers confront a changing ocean with hope
- Scientists say that the oceans are warming and absorbing more than 90% of the excess heat trapped by greenhouse gases in the atmosphere. These rising temperatures are placing growing stress on marine ecosystems, fueling coral bleaching, disrupting breeding cycles of marine organisms, and reshaping fish habitats.
- In the Western Indian Ocean – including along Kenya’s coast – warming is occurring faster than the global average in some places, raising fresh concerns for communities whose food security and livelihoods depend on the sea.
- Along the shores of Mida Creek in Watamu, one of Kenya’s best-known coastal destinations on Kenya’s Indian Ocean coast, fishers say they are already feeling the effects. Many report traveling farther offshore in search of fish and returning with smaller catches than they did a generation ago.
- During a recent reporting trip, Mongabay met fishers and women involved in the fish value chain who spoke about declining catches and fears for the future. At the same time, they pointed to local efforts to restore mangroves, protect fish breeding grounds, and clean beaches as reasons to hold on to hope for Mida Creek’s future.

Six marine sanctuaries recognized as Blue Parks, four of them in Africa
- On June 16, the Marine Conservation Institute recognized six marine protected areas, three in Madagascar and one each in Senegal, Chile and Canada, as Blue Parks.
- The awards, announced at the Our Ocean conference in Mombasa, Kenya, recognize MPAs whose management is “durable, equitable and effective” at protecting marine life.
- Under the Kunming-Montreal Global Biodiversity Framework, countries agreed to protect 30% of the world’s land, freshwater and marine areas by 2030, but experts say that protection must be meaningful, not just symbolic.
- One of the common features of the awardees is the existence of some form of co-management with Indigenous peoples and local communities.

Studying giant devil rays through war in Gaza: Interview with Mohammed Abu Daya
- Mohammed Abu Daya is a marine ecologist in Gaza. His research focuses on spinetail devil rays, a large-bodied species of ray that roams the Mediterranean Sea and beyond.
- Since 2013, Abu Daya has monitored the impact that local fisheries have on spinetail devil rays, which are listed as “critically endangered” on the IUCN Red List. Palestinian fishers occasionally target the rays when they stray into Gaza’s coastal water, as other fishing resources in the area have been depleted due to longstanding Israeli restrictions.
- Displaced by Israeli bombings during the war in Gaza that began in 2023, Abu Daya now lives in a tent, with limited access to basic necessities like food and drinking water, or to the internet. His university office has been destroyed, and he can no longer conduct research at sea. Yet he continues to carry out his scientific work, in the hope that it will help improve the conservation of devil rays globally.
- In 2025, at the height of the war, Abu Daya co-authored an international research paper documenting the behavior of spinetail devil rays and showing the importance of the Levantine region for the conservation of this species.

US moves to allow commercial fishing in Pacific marine protected areas
On June 11, U.S. President Donald Trump signed an executive proclamation to open additional commercial fishing grounds in remote areas of the Pacific. The proclamation says restoring access to these areas “will promote economic opportunity.” However, local groups warn it will open the door to overfishing in a crucial marine habitat and sacred cultural site. […]
Saudi parrotfish festival stretches scientific & traditional ecological knowledge (commentary)
- During the annual “hareed” festival in the Farasan Islands — an archipelago in the Red Sea off the coast of Saudi Arabia — hundreds of people run into the water to catch parrotfish, which aggregate there annually since time immemorial.
- Science cannot yet explain this annual phenomenon, but there are clues in traditional ecological knowledge and cultural history, a new op-ed explains.
- “Only by weaving [traditional] knowledge together with science can we begin to understand what we are trying to protect,” the author writes.

To help combat illegal fishing, 15 countries commit to sharing fisheries data
Fifteen countries from Africa, Asia, Latin America and Europe adopted the Mombasa Declaration on June 17, 2026. Together, they committed to advance global fisheries transparency and strengthen efforts to combat illegal, unreported and unregulated (IUU) fishing. The declaration was adopted during the 11th meeting of the international Our Ocean Conference, held in Mombasa, Kenya. Africa […]
Protect Antarctic krill to preserve the health of Africa’s coastal communities (commentary)
- African leaders must demand an end to industrial krill fishing in the Southern Ocean while at the Our Ocean Conference this week, before irreversible damage is done, Angola’s Minister of Fisheries and Marine Resources warns in a new op-ed at Mongabay.
- Antarctica and the ocean systems upon which Africa depends rely on krill — the tiny crustacean that gathers in huge swarms and which whales, seals, penguins and fish species feast upon — so letting business interests dictate how the base of this important food chain, that millions of people also benefit from, is irresponsible, she writes.
- “What happens in Antarctica affects the global ocean. That means the whales migrating along African shores, the resilience of our coastal communities, and the health and livelihoods of our coastal communities,” the minister argues. “Please join me in calling for an end to krill fishing now.”

How a popular spaghetti dish is threatening Italy’s marine ecosystem
- In the waters off Naples, Italy, a single 75-minute raid by poachers can net nearly 1,000 sea urchins, an in-demand ingredient in a dish popular with tourists. A haul like that can deal a significant blow to the local urchin population.
- In a healthy marine ecosystem, fish like sea bream feed on urchins, keeping populations in check. When poachers decimate sea urchin colonies, commercial fish move elsewhere to find food, threatening legal fishers’ livelihoods.
- Experts say Italy’s marine protected areas are particularly vulnerable. Although they have criminal penalties to deter poachers, the surrounding waters have been completely stripped bare of urchins, making them attractive targets.
- Now, scientists are collecting data from law enforcement operations to raise awareness and drive regulatory changes.

To improve its floundering fisheries, Kenya boosts data collection on artisanal fleet
- In Kenya, fishers are experiencing increased competition for dwindling catches. A lack of data is stymying their decision-making about where and when to fish as well as the governments’ decision-making about how to manage fishing in the country, experts say.
- A new project aims to improve the collection of fisheries data, harmonize them and make them accessible to fishers and the government alike.
- It involves beefed-up data collection methods, the installation of trackers on fishing vessels and a centralized database and digital platform.
- The initiative is modeled around a program in Timor-Leste that began in 2016 and now serves as the country’s national fisheries monitoring system.

In Indonesia’s Lombok, fishers find food security tied to mangrove reforestation
- On the east coast of Indonesia’s Lombok Island, local people who rely on the local crab fishery have initiated their own mangrove planting program in a bid to resuscitate failing crab habitats.
- The system is known as a silvofishery, which integrates mangrove forests with aquaculture cultivation to raise productivity.
- Instead of catching immature crabs from the coastline for quick sale, some local fishers have started to raise the crabs to adulthood alongside newly planted mangroves, garnering a higher price while overseeing a more sustainable population.
- However, local officials say a lack of technical training means most silvofishery initiatives have been forged through trial and error, and that expanding the system could result in greater mangrove planting in addition to boosting purchasing power in subsistence communities.

Four alleged wildlife traffickers arrested in Guinea, dried seahorses and shark fins seized
- Guinean authorities arrested four alleged wildlife traffickers and seized 41 kilograms of dried seahorses and 26 kilograms of shark and ray fins.
- The suspects are thought to be part of a transnational criminal network operating in West Africa involved in smuggling protected marine wildlife for more than four decades, and now face 1-5 years in prison and fines.
- The arrests were made when the accused were trying to sell seahorses to Chinese nationals in the country, who would then export them to China.
- The seizure highlights the growing role of West Africa as a source of the illegal global trade in marine species protected under CITES, the international wildlife agreement.

Malawi’s Elephant Marsh: The challenge of protecting a wetland that sustains thousands
- Elephant Marsh is one of Malawi’s most important fishing grounds, directly employing more than 4,000 people, with thousands more involved in processing and selling fish.
- But the marsh is under multiple pressures, including expanding settlements and farming, and deforestation, which is causing the wetland to shrink.
- The government of Malawi has established and empowered community groups to take on responsibility for conserving the wetland to sustain their livelihoods.

Tuna are rebounding. The work is far from done.
Tuna offer a useful case study for World Ocean Day because their recovery has come through the least sentimental parts of conservation: quotas, enforcement, stock assessments, and years of difficult diplomacy. By the early 2010s, several tuna stocks were in serious trouble. Atlantic bluefin had become a marker of overfishing. Pacific bluefin had fallen to […]
New records of ‘lost’ bamboo shark confirmed in Madagascar
For nearly 20 years, the blue-spotted bamboo shark, found only in Madagascar, went scientifically undetected and unrecorded. But researchers have now found four new records of the “lost” shark while surveying fishing villages and a Malagasy university’s fish collection. These recent records, and interviews with fishers, suggest the species may be more common than previously […]
Fisheries and climate research would be hit hard in Trump’s proposed budget
- In April, the Trump administration released its proposed fiscal year 2027 budget for the National Oceanic and Atmospheric Administration (NOAA).
- The proposed budget would slash around $1 billion from the agency, terminate or reduce dozens of programs, and eliminate more than 1,000 positions, with particularly deep cuts aimed at NOAA Fisheries and climate research.
- While the budget proposes many cuts to NOAA’s operations, it also recommends increased financial support for deep-sea mining development, vessel development, and the seafood industry.
- Experts say delayed release of already-approved funding is disrupting research, threatening long-term scientific data sets and hampering fisheries management, species protection and weather and climate monitoring. However, the Office of Management and Budget, which is responsible for dispersing NOAA’s funding, denies there have been delays.

Uncertainty about weakening Atlantic currents isn’t a reason to wait but to act (commentary)
- The Atlantic Meridional Overturning Circulation (AMOC) is the system of ocean currents that mediates weather on both sides of the Atlantic, and research suggests it’s shifting due to climate change in ways that threaten marine ecosystems, wildlife, agriculture and more.
- Though no one can yet prove how it’s changing and how soon, the latest research on the AMOC should be understood as a warning sign that the potential outcomes could be even more severe than projected, a new op-ed argues.
- “Discussions about AMOC weakening should not be confined to maps of temperature and rainfall. They should also be about biodiversity, fisheries, and the resilience of ocean ecosystems already under strain,” the author writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Shark Meat Nation
Brazil is the world’s largest consumer and importer of shark meat. But it’s not just restaurants and grocery stores — a Mongabay investigation found that the country’s government agencies have purchased thousands of tons of shark meat to serve in schools, hospitals, prisons, military bases, homeless shelters and other public institutions. The findings raise serious […]
Global sand demand is outpacing nature’s ability to replenish it, UN says
The global sand mining industry removes around 50 billion metric tons of material each year, outpacing the rate at which sand replenishes through the slow geological processes of weathering, reports Mongabay’s Carolyn Cowan. According to a report by the U.N. Environment Programme (UNEP), the demand for sand is expected to grow by 45% by 2060 […]
Davis “Yellowash” Washines, Yakama elder who spoke for the river and salmon
- Davis “Yellowash” Washines, a Yakama elder, public servant, ceremonial leader, and former police chief, devoted much of his life to defending Yakama treaty rights, clean water, and the Columbia River, known to the Yakama people as Nch’i-Wána.
- Drawing on his background in law enforcement, he described the toxic pollution at Bradford Island near Bonneville Dam as a crime scene, with the water, salmon, and people who depended on them as victims.
- His work joined law, culture, education, and public service: he served as Yakama Tribal Police chief, Columbia River Inter-Tribal Fish Commission police chief, Yakama Nation General Council chairman, counselor, language instructor, trustee, and board chair.
- The 2022 designation of Bradford Island as a Superfund site reflected years of persistence, but he saw the deeper goal as clean, healthy fish, safe water, and the fulfillment of responsibilities to future generations and those unable to speak for themselves.

What is happening to Thailand’s famous giant nets
SONGKHLA LAKE, Thailand — Jampen tends her Yo Yak lift nets and grandkids amid vanishing Luk Bre fish. As pollution threatens this ancestral tradition, villagers join researchers to build fish shelters, map routes with GIS, and innovate processing. Can local wisdom and science revive a fading way of life? Mongabay’s Video Team wants to cover […]
Tracking Lucero: Scientists follow a rare Eastern Pacific leatherback sea turtle
Fewer than 1,000 leatherback sea turtles remain in the Eastern Pacific, nesting along the coastline that runs from Mexico to Ecuador. Scientists have previously fitted tracking devices to leatherbacks on other beaches across Latin America and from bycatch near Ecuador. However, they recently tagged the first nesting leatherback in Ecuador, the southern limit of the […]
Iceland must protect wild salmon and reject new aquaculture legislation (commentary)
- Aquaculture and other factors like climate change pose a potentially mortal threat to wild Atlantic salmon, so a new bill in the Icelandic parliament should be rejected, Patagonia founder Yvon Chouinard argues in a new op-ed.
- More than 65% of Icelanders polled agree with him in opposing open-net salmon farming, which the bill would allow to expand despite the fact that it employs a small fraction of those working in the tourism sector, and which relies heavily on the nation’s natural beauty and healthy wildlife populations.
- “Icelandic ministers can listen to reason and citizens and set an example of responsibility, rather than giving in to the worldwide aquaculture industry,” Chouinard writes.

Countries push new protections for the Amazon’s iconic migratory catfish
- Around the world, migratory freshwater fish are in peril from activities including overfishing and, more recently, dams blocking their migratory routes.
- The most threatened species include two large Amazonian catfish, and an inaugural conservation plan will be implemented by the five countries where they range.
- Connected river habitat is crucial for the gilded catfish and Laulao catfish: They undertake some of the longest known river migrations in the world, traveling up to 12,000 kilometers (7,500 miles) over their lifetimes.
- The main challenge in saving these migratory catfish and many other aquatic species is maintaining connectivity among rivers, which in the Amazon are increasingly being affected by dams and shipping.

Indian Ocean tuna regulator eases yellowfin fishing curbs amid sustainability concerns
- During its annual meeting this month, the Indian Ocean Tuna Commission (IOTC) reframed management measures for yellowfin tuna following a determination that the species’ stock health has improved.
- Industry representatives welcomed the decision, but conservationists are urging caution, citing the long history of yellowfin overfishing and the difficulties in monitoring and curbing overexploitation.
- The IOTC also moved on regulating the swordfish fishery in the Indian Ocean by determining enforceable catch limits for members.
- Manta and devil rays are especially at risk in tuna fisheries; the IOTC adopted guidelines for their handling and release to reduce bycatch mortality.

Norlan Pagal, fisherman and guardian of Tañon Strait, died on May 14th, aged 56
- Norlan Pagal spent more than a decade defending the waters of Tañon Strait from illegal fishing.
- He survived dynamite, beatings and a 2015 ambush that left him paralyzed from the waist down.
- From his wheelchair, he continued watching the sea with binoculars and reporting violations to patrols.
- His work helped inspire other fishers to protect their waters and earned him recognition as an Ocean Hero.

Thai island community rallies to protect beloved dugongs, revive declining seagrass
- Seagrass beds around the island of Koh Libong in Thailand’s Andaman Sea have died off in recent years, part of wider nationwide declines scientists say have multiple, complex causes.
- The seagrass shortage has devastated the island’s once famed dugong population, jeopardizing tourism businesses and impacting the island community who have long protected them.
- Locals frustrated by slow government seagrass recovery plans are working with researchers and conservation groups to build citizen science skills and trial seagrass restoration techniques.
- Signs of hope are emerging, with recent surveys recording more dugongs in local waters, prompting local leaders to call for increased public awareness and enforcement of protections.

Rising waters and mounting pressures collide on Kenya’s Lake Turkana
- Lake Turkana in northern Kenya has risen by as much as 10 meters (33 feet) over the past 15 years, displacing communities, flooding infrastructure and reshaping fisheries in one of the country’s most climate-vulnerable regions.
- Scientists and local residents are still debating the causes of the lake’s expansion, with theories ranging from heavier rainfall linked to climate change, to tectonic and groundwater shifts, while researchers say Ethiopia’s Gibe III Dam upstream has also altered the lake’s ecological dynamics.
- Fishers around the lake say catches have declined sharply in recent years as changing water levels alter breeding grounds and fish distribution, while drought drives more pastoralists to rely on fishing for survival.
- Researchers and local advocates say Lake Turkana suffers from decades of poorly planned development and limited scientific monitoring, though new efforts are underway to improve data collection and guide more sustainable management of the lake and its fisheries.

‘Turkana has always adapted to change’: Interview with environmentalist Ikal Angelei
- Local livelihoods around Kenya’s Lake Turkana have long shifted between pastoralism, fishing, farming and trade as people adapted to a landscape defined by fluctuation.
- But as the scale and intensity of erratic climate patterns, mounting pressure on its fisheries, and conflict over resources has increased, their space has shrunk.
- The lake has long been a place where the poorest could make a living, but as the economic value of resources here increases, there is a risk that they will be pushed out by those better placed to access infrastructure and opportunities.

Philippine fishing and Indigenous communities wary of clean energy boom in Marcos stronghold
- The Philippines is currently highly dependent on fossil fuels for energy generation, but the government has committed to reaching 50% renewables by 2050.
- The resulting energy boom — especially in Ilocos North, the president’s home province — has seen an influx of foreign investment, but also raised questions about who will bear the costs of the country’s energy transition.
- Fishers in Ilocos Norte say they worry that wind energy projects in their traditional fishing grounds will disrupt marine life and fishing routes.
- Inland, the Masamuyao Isneg Yapayao tribal council is trying to stop the expansion of a solar farm that officials say failed to obtain the tribe’s consent.

Who controls Indian Ocean tuna?
The Indian Ocean hosts one of the world’s largest tuna fisheries, supplying global seafood markets and sustaining livelihoods across dozens of coastal nations. But scientists warn some stocks are under mounting pressure as foreign-owned industrial fleets continue to overfish tuna and coastal countries expand their fisheries — intensifying disputes over how the resource is managed. […]
19,000 Great Pyramids a year: Report flags unsustainable rate of sand mining
- A new analysis of global sand extraction indicates the industry is removing roughly 50 billion metric tons a year, a pace that far outstrips natural replenishment.
- Experts say the loss of sand from landscapes, river deltas, and coastal zones threatens ecosystems, livelihoods and many processes on which life depends.
- Although the sand mining industry is operating at unsustainable levels, experts say measures exist to lessen its impact.
- Solutions include coordinated governance, stronger monitoring and long-term, cross-border planning.

European bottom trawling costs billions every year in climate impacts, study finds
Europe’s fishing industry makes around 180 million euros ($210 million) every year in profits from bottom trawling, which involves dragging heavy fishing gear along seabeds. But a new study found when climate costs associated with the practice are calculated, society is paying a price up to 90 times higher than the fishing industry profits. “Bottom […]
Seabed life triples after bottom trawling ban in Scotland protected area
Nearly a decade since Scotland established the South Arran Marine Protected Area and banned bottom trawling across much of it, life on the seafloor has thrived, a new study has found. Scientists surveying the area found three times more seabed organisms and twice as many species compared to nearby unprotected waters. “What looks like […]
At world’s largest shark conference, scientists warn of a grim outlook across the board
- Hundreds of researchers and conservationists met in Colombo from May 4-8 for Sharks International, held once every four years.
- Major topics at the conference included the trade in shark and ray meat, reducing shark bycatch, and the use of new technologies in conservation.
- Participants also highlighted innovative programs that encourage community-based conservation, and grappled with the contentious topic of closing fisheries to aid recovery of threatened species.

China and Norway push to increase krill harvests around Antarctica
- In Antarctic waters, an international fishery targets krill, shrimp-like crustaceans that form massive schools and support the continent’s iconic wildlife. Krill meal and oil is used primarily in the production of aquaculture feed, followed by pet food and human dietary supplements.
- China and Norway are working to expand the Southern Ocean krill fishery, promoting a new management system for the fishery that would increase harvests while also establishing a long-sought marine protected area.
- The two countries are also continuing to support their krill fleets politically and financially, while adding vessels to increase harvest capacity.
- Meanwhile, several NGOs have recently stepped up their campaigns against krill fishing, arguing that the krill fleet competes for food with Antarctic wildlife species already struggling with climate change and reduced food availability such as emperor penguins and Antarctic fur seals that have both recently been declared endangered.

The Southern Ocean is key to our planet’s future & we have a chance to protect it this year (commentary)
- The wildlife-rich Southern Ocean is not simply another stretch of water in need of protection: just one part of it — the Antarctic Peninsula — is home to roughly a third of the global krill population, which sustains large populations of whales, penguins, seals, seabirds, fish and more.
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is responsible for governing these waters, and the U.K. is set to chair its pivotal 45th annual meeting this year.
- This is an opportunity to act on Southern Ocean conservation, a new op-ed by former U.K. environment minister Zac Goldsmith argues, but that’s not all: “It would also send a powerful signal, at a time when multilateralism is under strain, that countries can still come together around shared values and act for the global good,” he writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Sawfish in Sri Lanka may be ‘functionally extinct,’ but refuges remain
The sawfish, recognizable by its distinctive saw-shaped snout or rostrum, is now thought to be “functionally extinct” in Sri Lankan waters. This, researchers say, means that while a few individuals may still exist, their numbers are likely too low to maintain a viable breeding population, reports contributor Malaka Rodrigo for Mongabay. In a 2021 study, […]
Sour on the ‘blue economy,’ small-scale fishers seek ‘blue justice’ instead
- The blue economy is a somewhat ambiguous term that’s been used in international policy circles for the past decade and a half.
- The World Bank defines it as “the sustainable use of resources for economic growth, improved livelihoods, and job creation while preserving the health of ocean ecosystems.”
- In recent years, some small-scale fishers and coastal community members have started to question the blue economy agenda, arguing that it’s bad for them and the ecosystems they depend on — a kind of cover for business as usual.
- Groups of small-scale fishers are now working together across countries and continents to fight for their interests, and some are calling for “blue justice,” a concept that centers human rights and marine tenure rights.

Sharks and rays do not know boundaries and a new high seas treaty seeks to protect them
- A recent panel discussion at a global conference on sharks and rays explored how the newly adopted Biodiversity Beyond National Jurisdiction (BBNJ) Agreement, or the High Seas Treaty, could transform conservation of migratory sharks known to travel across national borders into international waters.
- Speakers highlighted sharks’ vulnerability once they leave protected national waters, emphasizing how effective conservation requires international cooperation to avoid threats from industrial fishing, bycatch, and habitat degradation across geographical boundaries.
- The treaty creates a legal framework for establishing marine protected areas in the high seas, with scientists noting that Important Shark and Ray Areas (ISRAs) could help identify critical migratory routes and habitats for future protection.
- Panelists said the agreement on BBNJ marks a historic shift in ocean governance, but warned that enforcement, political cooperation and coordination with treaties such as CITES, the Convention on Migratory Species and the Convention on Biological Diversity will be essential for meaningful shark conservation.

Dangerous arsenic levels detected in Thailand’s Mekong mainstream for first time
- Thai authorities have detected dangerous levels of arsenic contamination in sediment from the Mekong River mainstream and three of its tributaries in the country’s north.
- The contamination has been widely linked to a surge in unregulated mining, including for rare earth minerals, upstream in Myanmar’s Shan state.
- Experts warn that toxic heavy metals could threaten aquatic ecosystems, fisheries and the livelihoods of millions of people who depend on the Mekong Basin.
- Regional coordination and monitoring remain limited, with the Mekong River Commission lacking authority over key upstream areas in Myanmar and China.

In Senegal, artisanal fishing kills a surprising number of sharks and rays: study
- A study at two fish landing sites in southern Senegal found artisanal fisheries catch large numbers of sharks, rays and guitarfish, most of them threatened species.
- The authors suggest artisanal fishing may have a greater impact on these species than industrial trawling due to its large scale and limited monitoring and enforcement.
- Much of Senegal’s trade in artisanally caught sharks and rays is poorly monitored and exports take place without required permits, raising concerns about ongoing species population declines in the region, experts say.

A 10-year whale shark satellite study helps create new protected area in Indonesia
- Fishers and scientists joined together in Indonesia for a 10-year study to protect whale sharks (Rhincodon typus).
- The bagan fishers’ unique relationship with the endangered whale sharks enabled scientists to satellite tag the fish.
- The data from the decade-long study revealed previously unknown migration routes, feeding grounds and a whale shark nursery.
- The data will be used to help create a marine protected area designed for whale sharks.

With its first marine reserve, Ghana protects its ocean to secure its future (commentary)
- Last month, Ghana made news when it declared its first marine reserve and sited it in one of the nation’s most ecologically and biologically significant marine environments.
- Ghana’s minister for fisheries and aquaculture explains in a new commentary that the Greater Cape Three Points reserve will help restore marine ecosystems and protect the livelihoods of 21 coastal communities, while advancing the nation’s 30×30 conservation goal ahead of next month’s Our Ocean Conference in Kenya.
- “We urge governments everywhere to follow in Ghana’s footsteps to protect more of our ocean, invest in effective management, and ensure communities are at the heart of these efforts,” the minister writes.

Cambodia tested waters amid pollution claims; months later, still no public results
- Following local Indigenous Brao reports of health issues stemming from water since gold mining began in the area in 2023, Cambodian authorities tested water and sediment from the O’Ta Bouk River in February.
- To date, no results of water, sediment or fish sampling has been made public, despite experts urging more comprehensive testing and communities languishing in uncertainty over the safety of the river.
- All of this is taking place in Virachey National Park, one of Cambodia’s oldest and most remote protected areas, home to many endangered species, where the Cambodian government awarded an 18,900-hectare mining exploration license to a politically connected company.
- Brao fishers who live along the banks of the O’Ta Bouk River say there are no fish in the water, which they attribute to persistent problems linked to pollution; farmers who use the O’Ta Bouk’s waters for irrigation question whether to plant another year’s crops.

Migratory freshwater fish are in trouble: Will we act in time to save them?
- Migratory freshwater fish have declined by an estimated 81% since 1970 yet remain largely overlooked in global conservation policy. At the latest meeting of the Convention on Migratory Species (CMS), a new assessment identified 325 species worldwide in urgent need of coordinated protection.
- These long-distance swimmers underpin inland fisheries that feed hundreds of millions of people across the Amazon, Mekong, Congo and other river basins. By moving through river systems, they connect habitats, sustain food webs and support local economies.
- Dams, water extraction and habitat loss are rapidly severing migration routes, often cutting off access to spawning and feeding grounds. Scientists warn that without stronger protections, many migratory fish species — and the river systems they sustain — face an uncertain future.

World’s largest shark conference is set to begin in Sri Lanka next week
- When Colombo hosts Sharks International 2026 from May 4-8, it will be the first time a global shark and ray science conference is convened in Asia, drawing global attention to the region’s fisheries and biodiversity challenges.
- The conference will bring together leading global experts, policymakers and fisheries managers to strengthen the links between science, policy and practice, particularly in regions where shark fisheries are both economically important and ecologically under pressure.
- Key discussions will revolve around methods to bridge persistent gaps between shark conservation policy and on-the-water reality, and how regulations exist in formal frameworks but fail to translate into consistent awareness and action, compliance and enforcement.
- More than one-third of shark and ray species are now threatened with extinction globally, driven by overfishing, bycatch and international demand, making improved fisheries governance and enforcement a central focus of the 2026 meeting.

Global trade in sea cucumbers ‘alarming’ with many species at risk: Study
- The global trade in sea cucumbers has grown since 2013 and continues to decimate the populations of many species, according to a recent study that cites “escalating impacts” and calls for stronger conservation measures.
- The study found that global capture of sea cucumbers increased from 2013 to the late 2010s and dipped slightly during the peak pandemic years of 2020 and 2021, the last years in the study period.
- China and it’s special administrative region of Hong Kong, where sea cucumbers are used in traditional medicine and consumed as a delicacy on special occasions, are the main importers as measured by dollar value, the study found.

Marine resource conflicts in Africa revolve mostly around access: Study
- A new study identified more than 1,000 conflicts in Africa over an 11-year period and found that nearly 75% were disputes over access to spaces and resources.
- The study calls for more participatory and transparent governance to reduce conflicts, warning that without such reforms, conflicts could derail African policymakers’ sustainability and equity goals.
- The analysis, based on media reports and academic articles, found that the underlying drivers of the conflicts, some more direct than others, included illegal fishing, changes in distribution of benefits, weak governance and resource degradation caused by human activity.

Nearly three in four marine protected areas undermined by wastewater pollution
- A global modeling study found that 73% of marine protected areas are exposed to nitrogen pollution from wastewater — often at higher levels than in nearby unprotected waters.
- The findings indicate that marine conservation planning often fails to adequately account for land-based wastewater pollution or to integrate land-sea management.
- Wastewater pollution, largely untreated globally, introduces nitrogen and phosphorous nutrients and other contaminants that degrade marine ecosystems, with impacts on coral reefs, seagrass and water quality, and can undermine the effectiveness of MPAs.
- Addressing the issue is considered feasible but constrained by fragmented governance, underfunding and limited monitoring, despite solutions that include existing technologies, various policy proposals and examples of improved wastewater management.

NPFC adopts illegal fishing measures — but no Emperor Seamount protections
- The 10th annual meeting of the North Pacific Fisheries Commission (NFPC) took place April 14-17 in Osaka, Japan.
- While the NPFC members enacted new measures to combat illegal, unreported and unregulated fishing, leading NGOs criticized the commission for failing to act on bottom trawling in the Emperor Seamount Chain, a biodiversity-rich volcanic submarine mountain range in the Northwest Pacific.
- Some NPFC members and observers also expressed disappointment about backtracking on stock management and conservation for the Pacific saury, which is targeted by fishing fleets of several member countries.

Photos: A shark meat processing village and market in Indonesia’s Lombok
Shark meat has quietly surpassed shark fins in international trade volume and value. In East Lombok it sells for as little as 29 cents a skewer. Photojournalist Garry Lotulung documented the shark trade at Lombok’s Tanjung Luar fish market and nearby Rumbuk village, an important shark meat processing center. EAST LOMBOK, Indonesia — Indonesia consistently […]
Chile’s plan to protect another 10% of its ocean is stalled by the new government
The expansion of two vast Pacific marine parks near Chile has been suspended for six weeks, leaving protections for around 337,000 square kilometers (130,000 square miles) of ocean in limbo. Former President Gabriel Boric signed a decree creating marine parks Juan Fernández II and Nazca-Desventuradas II on March 10, his last day in office. Together […]
Oil spill continues in Gulf of Mexico vulnerable habitats, while Pemex admits fault
- An oil spill has contaminated 933 kilometers (about 580 miles) of shoreline along the western Gulf of Mexico, impacting the Mexican states of Veracruz, Tamaulipas, Campeche and Tabasco in eastern Mexico.
- After two months of contradictory theories about what could have caused the spill, Mexico’s national oil company, Pemex, admitted the spill was caused by a leak in one of its pipelines.
- Local communities have had to reduce or stop their fishing and ecotourism activities due to a lack of information from authorities about the risks of coming into contact with the water, and despite a government-led cleanup, residents continue to document damages to the environment, such as oil-slicked vegetation and intoxicated or dead fauna.
- Conservationists say the containment of the spill is urgent for the protection of more than 1,000 marine species, among them, endangered Kemp’s ridley sea turtles whose nesting season is underway on the beaches of northern Veracruz and Tamaulipas.

Study finds bottom trawling nets 3,000 marine fish species, including threatened ones
How many marine fish species do bottom trawls catch? Researchers now have a list, and it’s long, running to some 3,000 species, according to a recent study. Bottom trawling is a commercially popular, and controversial, fishing method in which boats drag weighted nets along the seafloor. Usually they target commercially valuable marine life at the […]
Goldman Prize winner Alannah Hurley fights Pebble Mine “from a place of love”
- Alannah Acaq Hurley, executive director of the United Tribes of Bristol Bay, has been awarded the Goldman Environmental Prize for organizing opposition to what would have been the largest open-pit mine in North America, called Pebble Mine.
- Proposed in 2001, Pebble Mine was vetoed in 2023 by the Environmental Protection Agency for posing a major threat to the abundant salmon fishery of Bristol Bay, in southeast Alaska. That veto received additional support this year in court by the Department of Justice.
- In an interview with Mongabay, Hurley discussed the long path she and the United Tribes of Bristol Bay’s coalition have walked to defeat Pebble, as well as the hurdles that remain ahead as the fight moves to court, and as UTBB pursues more comprehensive protections for the Bristol Bay watershed.

Asia’s longest free-flowing river contaminated by arsenic linked to Myanmar mines
- Independent testing of the Salween River began in September 2025 after researchers found alarming levels of toxic contaminants in the nearby Kok, Sai and Ruak rivers in Thailand, much of it linked to unregulated mining in Myanmar.
- Rare earth mines exporting crucial minerals needed for artificial intelligence, mobile phones, electric vehicles, renewable energy technologies and other uses have been blamed, but the mining of gold and various critical minerals also continues largely in secrecy across river basins in Myanmar.
- Most suspected mines were found upstream in the Salween’s basin, notably in Shan state, where various factions such as the United Wa State Army and the Myanmar National Democratic Alliance Army, as well as the Myanmar military, are fighting for territory.
- A working group was formed to address the growing issue of contamination across Thailand’s rivers, including the Salween, and tests showed arsenic levels at every monitoring point were more than double safety levels; news of the contamination has put local fishers and communities on alert.

Landmark US Magnuson-Stevens fisheries law turns 50 amid budget cut concerns
April 13 marked the 50th anniversary of the U.S. Magnuson-Stevens Act (MSA), a landmark conservation law credited with saving numerous U.S. fisheries from collapse and protecting vital ocean habitats. Despite decades of success, conservationists warn that recent federal funding cuts could undermine those gains. The MSA was passed in 1976, in the same decade the […]
Drones aid dugong conservation as threats mount across their range
- Drone technology is revealing new information about the elusive dugong, a marine herbivore classified as globally vulnerable but already extinct in parts of its range.
- Scientists are using drones to improve estimates of dugong numbers and conduct noninvasive health checks.
- Dugongs feed exclusively on seagrass meadows, where their foraging helps to maintain these important carbon sinks.
- Researchers are highlighting the need to link efforts to conserve seagrass meadows with protecting dugongs.

From carp to hippos, 43% of large freshwater animal species spread far beyond native ranges
From fish and turtles, to hippos and crocodiles, about 43% of all known large freshwater animal species have been deliberately introduced into ecosystems outside their native ranges, a recent study finds. Most species were introduced to boost fisheries, food security or tourism, but many have had unintended consequences for local wildlife, habitats and people. Fengzhi […]
Aaron Longton, fisherman who tied sustainability to survival
- Aaron Longton was a commercial fisherman in Port Orford, Oregon, who built his career through persistence and a deep understanding of the marine environment.
- He helped pioneer a model that connected fishermen directly with consumers, improving prices while increasing transparency around how seafood is caught.
- Longton argued that conservation and economic survival were inseparable, supporting science-based management and habitat protection to sustain fisheries over time.
- His work reflected the challenges facing small-boat fishing communities and offered a practical approach to maintaining both livelihoods and fish stocks.

Deep-sea wildernesses are more important than the promise of seafloor mining (analysis)
- A scientist who was part of a major 2008 expedition exploring the promise of deep-sea mining writes in a new analysis that what they found offshore of Papua New Guinea ended his enthusiasm for the nascent industry.
- The biodiversity documented by their remotely operated vehicle — added to the fragility and uniqueness of the geology and ecology they documented — was clearly too special to perhaps permanently decimate for electric vehicles and renewable energy.
- “I entered this project in good faith, working with the mining company to help determine whether or not deep-sea mining at Solwara I could be conducted with minimal harm to the marine environment. I exited convinced that there is no viable path forward for hydrothermal vent mining, anywhere in the ocean.”
- This article is an analysis. The views expressed are those of the author, not necessarily of Mongabay.

Ghana declares its first marine protected area
Ghana has declared its first marine protected area after more than 15 years of efforts to bolster marine conservation and safeguard its depleting fish stocks. Vice President Naana Jane Opoku-Agyemang announced the creation of the MPA on April 14. It marks a “historic moment,” according to Ghana’s fisheries commission, Benjamin Campion. The designated area covers […]
In northern Kenya, a shifting Lake Turkana reshapes traditional livelihoods
- According to Kenya’s environment ministry, water levels in Lake Turkana have risen by several meters in the past decade, expanding its total surface area by around 10%.
- The rise, mainly caused by increased rainfall far upstream, has affected communities and infrastructure on the lake’s shores, as well as disrupted fishing in its changing waters.
- Extended drought in surrounding areas has drawn thousands of new fishers to Lake Turkana, sometimes sparking conflict.
- The people who have lived here the longest are negotiating their survival in what a researcher calls “a system with many variables, both natural and human.”

Council recommends opening US Pacific marine monuments to commercial fishing
A U.S. fishing regulator recently recommended allowing commercial fishing across all four of the country’s Pacific marine national monuments. The Western Pacific Regional Fishery Management Council (Wespac) said the move is “about restoring sustainable fishing.” Conservationists and native peoples, however, say it will damage some of Earth’s most pristine ocean ecosystems. The monuments — Pacific […]
Half of seabirds are declining. Protecting marine flyways could help save them
- Nearly half of migratory seabird species are in decline, in part because conservation systems stop at borders while the birds do not.
- A new study maps six “marine flyways” spanning the world’s oceans, showing how 151 species depend on connected routes across dozens of countries.
- These pathways link breeding sites, feeding areas, and migration corridors, but face persistent threats from bycatch, invasive species, and climate change.
- Coordinating protection along these routes—rather than focusing only on isolated sites—could improve conservation outcomes for seabirds at a global scale.

How the US rebuilt a collapsed fishery
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. After this piece was published, we were informed that Aaron Longton had passed away. On the docks of Port Orford, a small fishing town on the southern coast of the U.S. state of Oregon, Aaron Longton runs a […]
EU citizens file complaint for delays in response to anti-shark fin campaign
The organizers of a campaign against shark finning in the European Union have filed a formal complaint against the EU Commission, accusing it of mishandling their case and missing deadlines. The European Citizens’ Initiative (ECI) is an EU tool that allow citizens to participate in policy-making. The ECI known as “Stop Finning – Stop the […]
Malawi says there’s been no illegal crayfish smuggling for a year
Authorities in Malawi have credited stronger monitoring and border controls with effectively ending the smuggling of invasive crayfish into the country, nearly a year after a major seizure from neighboring Zambia. Davie Khumbanyiwa, the fisheries department officer responsible for monitoring, control and surveillance, said the department has increased inspections for redclaw crayfish (Cherax quadricarinatus), a […]
Migratory species summit adopts new marine protections amid extinction warnings
- Delegates to the latest meeting of the Convention on Migratory Species of Wild Animals adopted new protections for 40 migratory species, including 33 marine animals like sharks, seabirds and shorebirds.
- The convention’s 15th Conference of the Parties (COP15), held in Brazil March 23-29, recognized the importance of “marine flyways” for migratory birds and highlighted key marine biodiversity areas.
- It also urged protection of seamounts from destructive fishing practices and a precautionary approach on deep-sea mining to address potential impacts on migratory species.
- Conservation advocates lauded the steps taken at COP15, but the summit also issued stark warnings that extinction and species decline are accelerating.

At high seas treaty summit, a dispute over fisheries managers’ role in conservation
- The high seas treaty was agreed to by the world’s nations in 2023 and took effect in January. The treaty created a means to establish marine protected areas (MPAs) in international waters, or the high seas.
- A summit to draft the treaty rules took place March 23-April 2 at the United Nations headquarters in New York City. Five multilateral organizations that manage high seas fishing, known as regional fisheries management organizations (RFMOs), jointly proposed changes in a bid to ensure their own work is not duplicated or displaced.
- The draft rules that emerged from the summit, to be voted on at a future meeting, accommodated the RFMOs’ wishes, according to critical observers, who argue the RFMOs are influenced by fishing industry priorities and may use authority conferred by the rules to inhibit MPA creation.
- In other news at the summit, parties also worked on developing rules governing the participation of non-state observers such as NGOs and a process for determining the location of the treaty’s secretariat.

Latin America’s largest hospital complex cancels plan to buy shark meat
- Last month saw a series of new policy developments for sharks in Brazil.
- Brazil’s biggest hospital complex said it would strike shark meat from a planned 2026 procurement, though the boneless fish could still be served at some of its institutes.
- The environment agency issued a host of new rules, including a ban on shark fins detached from the carcass, drawing ire from industry groups.
- A court ruled that federal procurements of shark meat for public institutions must meet new species labeling and traceability requirements.

10 years after Vietnam’s Formosa steel plant spill, justice for victims remains elusive
- This month marks the 10th anniversary of a marine disaster in Vietnam, caused by the release of toxic chemicals by the Formosa steel plant off the coast of Hà Tĩnh province.
- At least 100 metric tons of dead fish washed ashore beginning April 6, 2016, sickening thousands of people and shutting down the fishing and tourism industries.
- After widespread public mobilization, the company admitted responsibility and agreed to pay $500 million in compensation.
- Thousands of Formosa victims say they have not been properly compensated; lawsuits against the company are stalled; and victims and their supporters face repression, including imprisonment, inside Vietnam.

Talks to reduce funding for overfishing remain stalled at WTO meeting
- Delegates at a recent World Trade Organization summit in Cameroon agreed to continue “Fish Two” negotiations aimed at a deal to curb government subsidies that support unsustainable fishing, but progress remains limited, with just three countries blocking consensus despite broad support.
- The first phase of the deal, “Fish One,” entered into force in September 2025 and now has 116 ratifications; but key fishing nations, including India and Indonesia, have not joined.
- Disputes over Fish Two center on fairness: Developing countries argue the draft text disadvantages them, particularly through sustainability-based exemptions that favor wealthier nations with better scientific capacity.
- A four-year “sunset clause” triggered by Fish One’s entry into force now puts pressure on talks: If a full agreement is not reached by 2029, the entire deal, including Fish One, risks collapsing.

A ‘big book’ documenting Cameroon’s sharks & rays fills critical conservation gap
- Between 2015 and 2023, researchers working with fishers recorded more than 7,000 sharks and rays caught at sea and landed along Cameroon’s coast.
- The recorded animals represent 45 species, of which 13 are critically endangered.
- Their research found that most sharks and rays landed in Cameroon’s fisheries are juveniles, raising serious concerns about population recovery.
- The data help scientists better understand species composition, catch trends and conservation priorities along Cameroon’s coast.

State fishing village plan in Indonesian Papua sparks Indigenous opposition
- Indigenous Wiyagar leaders in Indonesian Papua oppose a planned state-backed fishing village, saying it’s being pushed without proper consultation on their customary land.
- The project is part of a nationwide program to build thousands of “modern” fishing settlements, a key plank of President Prabowo Subianto’s maritime development agenda.
- Critics warn the initiative risks “blue injustice,” as top-down planning may sideline local livelihoods, cultural systems and legal rights to participation.
- The dispute underscores broader tensions in Indonesian Papua over Indigenous land rights, with concerns that fast-tracked national projects could deepen land conflicts and environmental impacts.

With high seas treaty in place, West African countries plan for protected area
- West African nations are working on a proposal to establish one of the first high seas marine protected areas located beyond their national waters.
- The focus of the proposed MPA is the convergence zone between the Canary and Guinea currents, covering a biologically productive and ecologically complex marine zone that stretches from the maritime borders of Senegal to Nigeria.
- The region is a global biodiversity hotspot facing threats, including industrial fishing and plastic pollution, and is at risk from future deep-sea mining.
- The Economic Community of West African States (ECOWAS) members are aiming to finalize the proposal by the end of this year, but questions remain about how the management of the area will be financed and on monitoring and enforcement.

Investigation of permit violations in South Africa’s shark fishery pending
- In June 2025, South African authorities fined a shark fishing vessel caught violating its permit conditions.
- It is not the first time the country’s small shark fishery has made headlines, including for breaches of conditions by fishing in protected areas and illegally cutting heads and fins off of its catch, preventing effective monitoring.
- In October, the fisheries department said it would consider further action; no updates have been made public, but satellite data suggest the Zanette has fished inside a marine protected areas on at least four occasions since then.

Small ray of hope for Sri Lanka’s sawfish, now feared ‘functionally extinct’
- Known for its saw-shaped snout or rostrum, the sawfish is now feared “functionally extinct” in Sri Lankan waters, with the last record dating back to 2017.
- Three critically endangered sawfish have historically been reported in Sri Lanka — the narrow sawfish (Anoxypristis cuspidata), largetooth sawfish (Pristis pristis), and green sawfish (P. zijsron) — but they are listed as either endangered or critically endangered due to overfishing, habitat loss and bycatch.
- Researchers say small populations may still be surviving and call for more surveys to identify potential habitats toward conservation.
- The sawfish’s rostrum serves as both a weapon and a sensory organ, helping it to hunt prey in murky waters, and in Sri Lanka, these are traditionally offered to churches as a sign of goodwill.

The squid rush in the South Pacific is forcing regulators to act
A recent annual meeting of the fisheries regulator for the South Pacific tackled a familiar challenge: how to manage one of the world’s largest squid fisheries before mounting pressure turns it into a depleted one. The meeting produced some new safeguards, though much of the hard work still lies ahead, reports Francesco De Augustinis. The […]
325 Long-neglected migratory freshwater fish species need protection now: Report
- As national representatives gather at the UN COP15 Convention on Migratory Species (CMS) meeting this week in Brazil, a new global report has been released profiling a dangerously neglected category of migratory animal: the world’s freshwater fish.
- Migratory freshwater fish populations have fallen by 81% since 1970, says the report, with 325 species worldwide urgently needing coordinated international conservation action. However, only 23 migratory freshwater fish species are currently listed under CMS.
- More than half of the 325 at-risk freshwater migratory fish species documented by the report are in Asia, with the Mekong River of major concern. While international conservation cooperation is urgently needed, China and other Mekong basin nations are non-parties to CMS, as are the U.S. and Russia.
- What is needed now, conservationists say, are transnational migratory freshwater fish species conservation action plans that cover entire river systems, with those plans managed cooperatively by multiple nations within each river basin.

The ocean’s enforcement gap
- Governments have designated vast marine protected areas and pledged to conserve 30% of the ocean by 2030, enforcement often lags behind these commitments.
- Research shows that the ecological benefits of marine protected areas depend less on their size than on whether rules are visible, monitored, and enforced.
- New tools—such as satellite imagery, vessel-tracking systems, and data analytics—are making it easier and cheaper to detect illegal fishing and focus enforcement efforts.
- As monitoring improves, the future of ocean conservation may depend less on creating new protected areas than on ensuring existing rules are consistently applied.

Contested Amazon dam called to review water flow as river ecosystem fails
- A federal court and Brazil’s environmental agency ordered the Belo Monte hydropower plant to revise the Xingu River’s water-sharing plan, a decade after its debut, but a legal stay blocks enforcement of the ruling.
- The plant’s water flow has been subject to several complaints, as low water levels in the Volta Grande do Xingu have dried flooded forests and rock habitats, disrupting fish and turtle reproduction and threatening endemic species.
- “Increasing the amount of water is the only solution to restore this ecosystem,” says Josiel Juruna, coordinator of an Indigenous-led monitoring program documenting the impacts.

The hidden cost of fisheries subsidies
- Governments provide roughly $35 billion a year in fisheries subsidies, much of it supporting fleets that can operate beyond what fish stocks alone would sustain.
- Research suggests many high-seas fisheries would be unprofitable without public support, raising questions about whether some “productive” fishing activity exists largely because of subsidies.
- Recent efforts such as the WTO fisheries subsidies agreement aim to curb support tied to illegal fishing and depleted stocks while improving transparency around how governments finance their fleets.
- Treating oceans as assets on the public balance sheet—from reforming subsidies to investing in monitoring and coastal ecosystems—could help governments reduce long-term fiscal risks while supporting healthier fisheries.

An ancient fishing tradition in Indonesia could help build a more sustainable fishery
In the remote coastal areas of eastern Indonesia, a centuries-old tradition is providing a contemporary blueprint for sustainable development. The practice, known as Sasi Laut, imposes temporary fishing closures of six to 12 months to allow sedentary marine species such as sea cucumbers and shellfish to replenish. A new study published in Marine Policy reveals […]
Outlook for migratory species worsens amid habitat loss & avian flu, report finds
- A U.N.-backed report finds that nearly half of the world’s migratory species protected under a global treaty are now decreasing — and about one in four now faces extinction.
- Habitat loss and degradation as well as hunting and fishing are driving these declines, but a deadly virus, Highly Pathogenic Avian Influenza, is also taking a heavy toll on bird populations.
- Wildlife corridors and protected ocean networks can play a pivotal role in conserving imperiled species: Animals need to move to find food, a mate and migrate.

Modest controls put on freewheeling squid fleet at South Pacific fisheries meeting
- The 14th meeting of the South Pacific Regional Fisheries Management Organisation (SPRFMO) took place in Panama City from March 2-6.
- The intergovernmental organization regulates fishing activities in the high seas of the South Pacific, a vast area encompassing about 59 million square kilometers.
- Key decisions concerned tightening regulation of the jumbo flying squid fishery following increased fishing activity and signals of overfishing, and adopting measures to reduce illegal fishing practices and labor abuses in the squid fleet.
- Decision-makers also took steps toward finalizing a new management procedure for jack mackerel. Negotiations over regulating bottom trawling, a source of disagreement at recent SPRFMO meetings, remained stalled.

Bangladesh sees rise in ray, shark fishing as traditional seafood species dwindle
- Bangladesh has seen a sudden rise in illegal shark and ray fishing and consumption in recent years.
- A decrease in catch of traditionally consumed fish species and the lower prices of sharks and stingrays have led to this rise in popularity. Additionally, traders export ray skins and shark parts to East and Southeast Asian countries.
- Sharks and rays are protected species in Bangladesh and existing laws prohibit their catching, selling and consumption.
- Conservationists blame the weak law enforcement and lack of awareness among fishers and suggest that the government initiate stricter conservation measures besides providing subsidies to the poor fishers.

Pascale Moehrle pressed Europe to take its seas seriously
- Pascale Moehrle, who led Oceana’s European office from 2019 to 2025, spent more than four decades working on wildlife conservation and ocean policy.
- Her death was announced by Oceana on March 4, 2026.
- Moehrle pushed European governments to follow scientific advice on fisheries, curb destructive fishing practices and enforce protections in marine protected areas.
- Her work focused on turning Europe’s commitments on ocean protection into practical policy that could restore marine ecosystems and sustain fisheries.

Antarctic krill sustainability label questioned
The Marine Stewardship Council (MSC) recently released a draft report for its fourth recertification of krill fishing in Antarctica by Aker QRILL Company. The certification would allow Aker to put an MSC label on its products that tells consumers the krill came from a sustainable well-managed fishery. However, the Antarctic and Southern Ocean Coalition (ASOC), […]
25 years after ‘disaster’ declaration, major U.S. fishery makes a comeback
- In 2000, the U.S. commerce secretary declared the groundfish fishery on the U.S. West Coast a “disaster,” with 10 key species overfished to below a quarter of their healthy levels.
- Fisheries authorities empowered by federal conservation laws took drastic action: They cut off vast tracts of the ocean to trawling, slashed fishing quotas and bought fishing vessels to remove them from operation. Many fishers were thrown into painful retirement.
- Careful management and innovation in the intervening years has led to a remarkable turnaround: In October 2025, fishery officials declared the last of the 10 overfished species to be rebuilt, years earlier than expected, and fishers have catches they thought would never be possible again.
- Even so, fishers’ profits have been low, and experts worry that key conservation programs could lose their teeth to cost-cutting measures and deregulation.

Seafood fraud is rampant, imperiling fish populations, report finds
- Up to roughly 20% of aquatic products are intentionally mislabeled as the wrong species or otherwise fraudulent, posing environmental and health risks, according to a new report.
- Inaccurate representation of species is one of the most frequent forms of fraud, the report says.
- Other cons include misrepresenting place of origin or eco-certification status, and adulterating a product to affect its weight or appearance of freshness.
- The report calls for governments and industry stakeholders to establish better traceability systems, use advanced detection methods, and educate the public. An NGO expert says government action on traceability is key.

China’s Pacific squid fishery rife with labor, fishing abuses: Report
- A new report from U.K.-based NGO the Environmental Justice Foundation draws on interviews with 81 fishers, mainly Indonesian sailors who worked between 2021 and 2025 on 60 Chinese vessels targeting jumbo flying squid (Dosidicus gigas) in the Southeast Pacific Ocean.
- It documents frequent labor abuses affecting crew members, including several indicators of forced labor as described by the International Labour Organization.
- The report also documents regular shark finning, targeted hunting of marine mammals, and involvement in suspected illegal fishing incidents, often inside Ecuador, Peru or Chile’s exclusive economic zones.
- The report was launched days before the annual meeting of the commission of the South Pacific Regional Fishery Management Organisation, the intergovernmental body that manages the fishery. Officials with fishing organizations mentioned in the report and members of China’s delegation to the meeting did not respond to Mongabay’s request for comment on the report.

Displaced for conservation, South Africa’s Thonga try to keep a fishing tradition alive
- A Thonga community on South Africa’s northeast coast is the custodian of a centuries-old fishing custom and its ecological knowledge with a light touch on migrating juvenile fishes.
- These fishers have limited access to their ancestral lands and lakes now, since they were evicted when the region was declared a protected area four decades ago, which later became the iSimangaliso Wetland Park.
- Three generations of fishermen talk about how they’re trying to keep the culture alive in a fast-changing world.
- The park’s management authority says they are inclusive of communities in public participation processes while officials promise that tourism would be the most viable development boost for the area.

The power of cities over the seas
- Much of what determines the ocean’s condition is decided on land, where ports control entry, cities regulate ship operations, and municipal buyers shape seafood demand. These urban levers can influence marine outcomes at scale even though they receive far less attention than treaties or national policy.
- Port rules on fuel use, emissions, and safety can compel global shipping companies to change behavior, as access to major trade hubs is too valuable to lose. When several large ports adopt similar standards, their combined weight can shift industry norms across entire maritime corridors.
- Public procurement provides another pathway, with city-run institutions able to influence fisheries through what they choose to purchase. Sustainability standards — or public scrutiny, as seen in Brazil’s school meal controversy — can ripple back through supply chains and alter incentives at sea.
- Philanthropy focused on oceans may find high leverage in supporting city-level actions such as port electrification, data-sharing systems, and procurement reform. By targeting where rules meet markets and infrastructure, urban governance can complement national efforts and deliver practical gains even when international cooperation falters.

Senegal GTA gas project draws international scrutiny
The UK’s OECD national contact point (NCP), which oversees complaints related to corporate conduct with the Organisation for Economic Co-operation and Development (OECD) has ruled admissible a complaint from Senegalese fishers alleging wrongdoing by energy companies in Senegal. A local NGO and an artisanal fishers’ association assert that the natural gas platform Grand Tortue Ahmeyim […]
How cockfighting imperils Peru’s critically endangered sawfish
- Mongabay’s new film “Why cockfighting is threatening Peru’s last sawfish” investigates how the critically endangered largetooth sawfish has become a victim of Peru’s legal cockfighting industry.
- Although the species has nearly disappeared from Peru’s Pacific waters, its rostral “teeth” continue to circulate in informal markets, prized for use as cockfighting spurs.
- A single sawfish can yield dozens of spurs, each worth up to $250, creating powerful economic incentives for artisanal fishers facing financial hardship.
- Through interviews with fishers, scientists and cockfighting industry leaders, the film explores whether cultural change within the sport can outpace the illegal trade before the species disappears entirely.

Mongabay shark meat exposé wins national journalism education award in Brazil
- On Feb. 24, Mongabay won first place in the higher education category of Brazil’s National Association of Directors of Federal Higher Education Institutions (Andifes), a top journalism education award in the country, with an investigation that revealed Brazilian state-run institutions were bulk-buying shark meat for public schools, hospitals and prisons.
- “The work stands out for its expert input from specialists and researchers, who contribute to the analysis of the environmental, health and regulatory impacts of the issue,” Andifes said in the announcement.
- In collaboration with the Pulitzer Center, the investigation published in July 2025 tracked 1,012 public tenders issued by Brazilian authorities since 2004 for the procurement of more than 5,400 metric tons of shark meat, worth at least 112 million reais.
- In December 2025, the investigation won second place in the national category of the 67th ARI/Banrisul Journalism Award, one of Brazil’s most prestigious journalism prizes.

Photos: In the Colombian Amazon, fishing binds a community to river and forest
- For members of the Macaquiño community in the southeastern Colombian department of Vaupés, fishing forms part of the deep cultural and spiritual connection they have with their waters and the species that inhabit it.
- The introduction of more intensive modern fishing gear, such as using longlines and mesh nets, has had an impact fish populations and has contributed to a decline in the use of some ancestral fishing practices, they said.
- Community elders told Mongabay that while some traditional fishing tools are still used today, few people know how to make them, raising concerns that fishers may eventually turn to other techniques that can damage habitats and reduce fish species.

Brazil revokes decree privatizing three Amazonian rivers after Indigenous protests
Brazil has revoked a presidential decree that placed sections of three Amazonian rivers — the Tapajós, Madeira and Tocantins — under a state-led privatization program. Indigenous groups had protested the plan for 33 days by blockading a Cargill grain port in Santarém in the western Brazilian Amazon. The decree was a part of a larger […]
Amazon riverfolk warn blasting rocks for shipping route will kill fisheries
- As Brazil moves to explode the deep, rocky river territory of the Lourenção Rocks, locals on the Tocantins River say the government’s refusal to recognize them as “impacted” excludes thousands of fishers from protections.
- Scientists compare the 43-kilometer (26.7-mile) rocky stretch to an “underwater Galapagos,” warning that detonations will destroy the quiet water pockets and deep rocks where rare species breed.
- The industrial shipping route is designed to accelerate global exports of soy and minerals, a move critics say prioritizes corporate profit over the survival of traditional peoples.

Azores dodges proposal to overturn no-fishing zones in its giant new MPA network
- A law establishing the Azores Marine Protected Areas Network was approved in October 2024 and took effect recently, on Jan. 1 this year.
- The network now safeguards 30% of Azorean waters, 287,000 square kilometers of seascape sheltering a rich array of marine life, and makes up the largest MPA network in the North Atlantic Ocean.
- Not two weeks later, on Jan. 15, the Azores Parliament voted on a measure that upholds a core provision of the MPA network, after it came under fire in recent months: No fishing inside the fully protected areas, which constitute half the vast network.
- Conservationists expressed satisfaction, broadly, with the agreement, but fishers’ groups expressed disappointment.

It’s electric: Scientists develop cheap way to keep sharks off fishing hooks
- Unintentional catch is a major reason that more than a hundred shark species are threatened with extinction.
- A new study found that creating a small electric field around fishing hooks using zinc and graphite is enough to keep many sharks away.
- Researchers have for decades tried to take advantage of sharks’ electrosensitivity to develop devices to keep them off fishing hooks. The authors of the new study chose zinc and graphite because they’re nonmagnetic, cheap and readily available materials.
- The lead author and two former students are pursuing commercial applications for the new method.

Migrant fishers’ deaths at sea tied to unchecked captain power, study shows
- A new study finds migrant fishers’ deaths at sea stem from systemic labor and governance failures, not isolated safety lapses.
- Far from shore, captains control food, medical care and even how deaths are recorded, with little oversight or accountability.
- Researchers documented 55 cases of Indonesian fishers who died or went missing, showing deaths occur through both direct abuse and prolonged neglect.
- The authors call for stronger international cooperation, mandatory death reporting and supply chain transparency, arguing existing rules alone cannot prevent further fatalities

New study assesses geoengineering marine ecosystem risks, knowledge gaps
- A new review study examines the current research regarding the risks that various geoengineering approaches pose to marine ecosystems.
- The study looked particularly at a range of marine carbon dioxide removal (mCDR) methods, along with solar radiation modification (SRM) technologies, and found that some approaches carry fewer risks than others.
- Electrochemical ocean alkalinity enhancement and anoxic storage of terrestrial biomass in the deep ocean (utilizing crop waste, for example) carry fewer risks to marine ecosystems than some carbon dioxide removal methods, such as those that would add nutrients to seawater to promote major plankton growth.
- However, better models, increased field testing, and better geoengineering regulatory oversight are needed to fully assess potential geoengineering marine ecosystem impacts, especially if commercialization proceeds. Public fears over field testing also need to be allayed.

Fishers denounce plummeting fish stocks following Amazon hydroelectric dam
A hydroelectric dam impacting Brazil’s Amazonas and Rondônia states have slashed fished populations by as much as 90% in some locations, according to a new a study based on on-the-ground research in partnership with riverine communities. The 2008 construction of the Santo Antônio hydroelectric dam dramatically reduced the natural flow of the Madeira River, which […]
Farmers fear displacement, drought, flooding tied to Cambodia’s Funan Techo Canal
- The Cambodian government is set to begin construction of the Funan Techo Canal, a nearly $1.2 billion, 180-kilometer (112-mile) waterway navigation project that will cut across four provinces to connect the Mekong River to the sea.
- The primary rationale for building the canal is to reduce Cambodia’s shipping costs, as well as to generate jobs and economic development.
- Mongabay has followed this mega-project’s development for more than a year, speaking with more than 50 people living along the canal’s proposed route. Virtually everyone we spoke with noted that the government has provided very little information about the project, and amid the uncertainty, fear has taken root.
- In inland communities in the rich floodplains of the Mekong River, farmers we spoke with said they worried they’d lose their homes or land, and that construction would disrupt the annual months-long inundation of the wetlands they rely on for planting rice as well as for fishing, crabbing and raising livestock.

Sustainable fisheries can’t be built on exploited labor (commentary)
- The connection between human welfare and ocean conservation is direct and unavoidable, a new op-ed argues, because lawlessness toward people often goes hand in hand with lawlessness toward the ocean.
- Although there is an international legal framework governing crew welfare on fishing vessels at sea, these protections remain uneven, weakly enforced, or entirely absent for too many fishing crews, particularly migrant workers deployed on distant-water fleets.
- “We cannot reasonably expect crews to comply with complex fisheries regulations including logbooks, bycatch mitigation, finning bans, spatial closures and other requirements when they are overworked, underpaid, isolated and afraid,” the author writes.

Trump opens only US marine national monument in Atlantic to fishing — again
- U.S. President Donald Trump issued a proclamation on Feb. 6 to open the Northeast Canyons and Seamounts Marine National Monument, a marine protected area off the northeastern U.S., to commercial fishing.
- Trump wrote that reopening the area will not endanger marine species and will help the fishing business, and industry groups praised the proclamation.
- Conservationists decried the move, saying the monument is a critical sanctuary for marine life and the food webs that serve the interest of the U.S. public.
- The Trump administration has also moved to deregulate the other U.S. marine national monuments, which are in the Pacific Ocean.

Mexico considers shrinking protected areas for endangered vaquita porpoise
- Officials in Mexico are considering shrinking a protected area in the Gulf of California, the stretch of water between Baja California and mainland Mexico where the vaquita (Phocoena sinus) is endemic.
- The vaquita is the world’s smallest porpoise and the most endangered marine mammal, with only an estimated 10 individuals remaining.
- The proposal, not yet public but reviewed by Mongabay, would reduce a gillnet prohibition zone and allow traffic through a zero-tolerance area where all vessel activity is currently banned.
- The Ministry of Environment and Natural Resources and other agencies are developing the new regulations, but it’s unclear when they will be implemented.

Cambodia’s canal mega-project threatens coastal communities and marine life
- The Cambodian government is set to begin construction of the Funan Techo Canal, a nearly $1.2 billion, 180-kilometer (112-mile) waterway navigation project that will cut across four provinces to connect the Mekong River to the sea.
- The primary rationale for building the canal is to reduce Cambodia’s shipping costs as well as to generate jobs and economic development.
- Mongabay has followed this mega-project’s development for more than a year, speaking with more than 50 people living along the canal’s proposed route. Virtually everyone we spoke with noted that the government has provided very little information about the project, and amid the uncertainty, fear has taken root.
- In coastal communities in Kep province, where the canal will meet the sea and a new port and deepwater shipping lanes will be built, fishers we spoke with said they worried they’d lose their homes and that construction would render their already meager fishing grounds barren and inaccessible.

Abandoned tuna-fishing devices pollute the Galápagos Marine Reserve
- The tuna industry commonly uses fish aggregating devices (FADs) to efficiently collect large volumes of fish; when these devices are lost or abandoned, they can harm marine wildlife and habitats.
- In Ecuador, lost FADs can drift into the Galápagos Marine Reserve, a protected area with hundreds of endemic and threatened species, where they pollute the environment with plastic, harm reefs and entangle wildlife.
- Local agencies and organizations are developing ways to prevent FADs from entering the marine reserve in the first place and trying to clean up the mess they make when they do get in.

Critical shark and ray habitats in Western Indian Ocean largely unprotected: Study
- Almost half of the Western Indian Ocean’s shark and ray populations are considered threatened with extinction, as populations decline.
- The Important Shark and Ray Areas (ISRAs) project has mapped out 125 areas across the Western Indian Ocean that are critical for the survival of many species.
- Yet only 7.1% of these ISRAs fall within existing marine protected areas, and just 1.2% are in fully protected areas where fishing is prohibited.
- Researchers identified challenges related to fishing pressure as the most significant threat to sharks and rays in the region.

Whale sharks released from nets along India’s coast as fishers turn rescuers
- Once hunted and butchered for oil and meat, whale sharks (Rhincodon typus) are now being rescued by fishers along India’s western Arabian Sea coast.
- Since 2001, the nonprofit Wildlife Trust of India has been educating fishing communities about whale sharks, training fishers in safe disentanglement techniques and offering compensation for destroyed nets.
- During that time, more than a thousand whale sharks have been released from accidental entanglement in fishing nets along India’s west coast.
- However, experts say the compensation for rescues remains insufficient and that social security, insurance, training and livelihood-linked incentives should be offered to protect the fishers who engage in whale shark rescues.

In the Brazilian Amazon, community conservation success comes with a cost: Study
- In Brazil’s western Amazon, community-led efforts to protect the pirarucu, one of the world’s largest freshwater fish, bring conservation benefits that extend into upland ecosystems.
- A study in Nature Sustainability found that by patrolling oxbow lakes along the Juruá River, communities effectively protect a mean area 86 times larger than the lakes they directly monitor, making this the largest community-based conservation initiative in the Brazilian Amazon.
- Local families bear the full economic burden of conservation efforts; surveillance represents 32% of total costs and reduces community income by 21%. Researchers say that using payments for environmental services would help ease pressure on communities.

Rio de Janeiro state bans shark meat for school meals
- The government of Brazil’s Rio de Janeiro state has banned shark meat for meals in most of the schools it manages, after pressure from conservationists and school meal advisers raising health and environmental concerns.
- The shark meat ban applies to all 1,200 schools run by the state education department, but not to the thousands of other schools in the state that are managed by municipalities and private entities.
- A Mongabay investigation in July 2025 revealed 1,012 public tenders issued since 2004 to procure more than 5,400 metric tons of shark meat in 10 of Brazil’s 26 states, including Rio de Janeiro.
- Industry groups have criticized the Rio de Janeiro government’s decision, dismissing health risks linked to shark meat consumption, and complained of a lack of transparency in the decision-making process, noting that the ban has yet to be published in the state’s official gazette.

Making 60% of the ocean manageable (Commentary)
- A new UN treaty, BBNJ, has entered into force to create the first global framework aimed explicitly at conserving biodiversity on the high seas, where industrial activity has expanded faster than oversight. The agreement matters less for its text than for whether it can be translated into real-world governance and enforcement.
- The high seas have never been lawless, but they have been managed through fragmented sector-by-sector institutions, leaving biodiversity as a secondary concern. BBNJ attempts to close that gap without replacing existing bodies, which creates both opportunity and friction.
- The treaty’s success will hinge on practical systems: transparent environmental assessments, credible monitoring, and the capacity for more countries to participate meaningfully. Technology can make harmful activity harder to hide, but it cannot substitute for political will and durable enforcement.

From south to north, Sri Lanka’s cricket dreams undermine fragile ecosystems
- Sri Lanka plans to construct an international cricket stadium and a sports complex on the northern island of Mandaitivu spanning more than 56 hectares to popularize the sport in the country’s Northern province.
- Mandaitivu overlaps with mangroves and coastal wetlands in the ecologically sensitive Jaffna lagoon, and environmental groups warn that a construction on the low-lying island could reduce flood retention and increase climate vulnerability.
- Mandaitivu’s mangroves support fisheries and coastal livelihoods causing concern about potential decline in aquatic creatures, especially prawns and crabs, impacting the traditional fisherfolk.
- Conservationists say the project echoes past ill-informed infrastructure decisions, such as the Hambantota stadium built within an elephant habitat, reflecting weak environmental governance and repeated ecological trade-offs.

Mike Heusner, steward of Belize’s waters, has died, aged 86
For a small country, Belize has long carried an outsized reputation among people who care about water. Its flats and mangroves, its reef and river systems, have drawn anglers and naturalists who come for beauty but stay, if they are paying attention, for the fragile bargain that keeps such places alive. Tourism can finance protection. […]
Mauritania’s fishmeal fever ends as government tightens regulation
- Until recently, Mauritania was a major fishmeal producer, home to the world’s second-highest number of processing plants, with the boom driven largely by lax regulations and the rapid issuance of permits between 2007 and 2021.
- By 2021, more than half of Mauritania’s total pelagic fish catches were being used for fishmeal.
- That same year, however, the government began introducing stricter regulations and strengthening enforcement of rules governing the sector.
- Only eight fishmeal plants in Mauritania remain active as of September 2025, according to Mongabay’s estimates, and fishmeal production has fallen by more than half since its peak in 2020.

Cowboy boots made from pirarucu leather fund Amazon’s sustainable fishery
- Sustainable pirarucu fisheries in Brazil’s Amazonas are restoring once-depleted populations of this freshwater giant, thanks to community-led management systems and sales to brands overseas.
- Selling pirarucu skin to the fashion industry, especially for Texas-bound cowboy boots, is key to financing the fishery, helping maintain fair prices for fishers and cover part of the high costs of transport, storage and community monitoring.
- The system depends on heavy collective labor and constant protection against illegal fishing, with communities traveling long distances, patrolling lakes and facing armed threats — all while receiving limited recognition or policy support from authorities.

Azores must respect its exceptional network of marine protected areas (commentary)
- Just over a year ago, the Azores created the largest network of marine protected areas (MPAs) in the North Atlantic, becoming a beacon of hope and a global leader in ocean conservation.
- Then, in early 2025, a proposal to allow tuna fishing in “no-take” areas there was submitted to the Regional Assembly; this is currently under discussion and could come to a vote this week or next week.
- “Such a retreat from ocean protection would not only be a local tragedy but also a disheartening contribution to the global backpedaling on environmental political will,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Up close with Mexico’s fish-eating bats: Interview with researcher José Juan Flores Martínez
- The fish-eating bat (Myotis vivesi) catches fish and crustaceans thanks to its long legs, hook-shaped claws and waterproof fur.
- The species is found only on islands in Mexico’s Gulf of California; it’s considered endangered under Mexican law.
- Invasive species such as cats and rats threaten the bats.
- Researcher José Juan Flores Martínez has been studying fish-eating bats for more than 25 years, and discusses his fascination with the species and the threats it faces.

Fish deformities expose ‘collapse’ of Xingu River’s pulse after construction of Belo Monte Dam
- Independent monitoring has found a high prevalence of deformities in fish in the Volta Grande do Xingu area of the Brazilian Amazon, following the construction of the massive Belo Monte dam.
- Potential factors could include changes in the river’s flood pulse, water pollution, higher water temperatures, and food scarcity, all linked to the reduced flow in this section of the Xingu since the dam began operating in 2016.
- Federal prosecutors are scrutinizing the dam’s impact, alongside independent researchers, and at the recent COP30 climate summit warned of “ecosystem collapse.”
- Both scientists and affected communities say the prescribed rate at which the dam operator is releasing water into the river is far too low to simulate its natural cycle, leaving the region’s flooded forests dry and exacerbating the effects of drought.

Fishing ‘modernization’ leaves Tanzania’s small-scale crews struggling to stay afloat
- Tanzania’s boat modernization program aims to empower small-scale fishers with affordable, government-distributed vessels, but has instead left many struggling with unreliable vessels and unsustainable loans.
- In Kilwa district, fishers say the boats they received were poorly equipped, costly to operate and prone to mechanical failure, forcing them to rent missing gear and spend more on fuel.
- Mounting repayment pressure is driving some fishers toward illegal or risky fishing practices, undermining the project’s goal of promoting sustainability.
- Experts warn that poor consultation, mismatched designs and a lack of community input threaten to turn Tanzania’s fisheries modernization plan into a long-term burden rather than a solution.

Amazon fishers help scientists map dam harms to Madeira River stocks
- Having fishers as protagonists, a recent study disclosed unanswered details about the Amazon communities and fish species most affected by two Madeira River dams.
- The dams limited the natural flow of the Madeira, disrupting the currents that fish need and causing up to a 90% reduction in stocks in some locations; species like pirarucu and tambaqui have largely disappeared from traditional fishing communities.
- The research serves as evidence to support the decade-long legal battle by fishers in Humaitá who are seeking compensation for losses caused by power plants.

Top ocean news stories of 2025 (commentary)
- Marking the midway point in the U.N. Decade of Ocean Science for Sustainable Development, 2025 was a key year for the ocean.
- The past 12 months brought landslide multilateral wins for ocean policy, unprecedented ocean financial commitments, and increasing momentum to protect 30% of the ocean by 2030.
- Here, marine scientists, policy experts and a communications expert lay out the key ocean stories from the past year.

Mongabay shark meat investigation wins national journalism award in Brazil
- A Mongabay investigation that revealed Brazilian state-run institutions bulk-buying shark meat for public schools, hospitals and prisons won second place in the ARI/Banrisul Journalism Award, one of Brazil’s most prestigious journalism prizes.
- In collaboration with the Pulitzer Center, Mongabay revealed how authorities had issued 1,012 public tenders since 2004 for the procurement of more than 5,400 metric tons of shark meat, raising environmental and public health concerns.
- In a statement, the Rio Grande do Sul Press Association (ARI) said the award “recognized the talents” in professional and university categories amid a record number of entries, up 40% from the 2024 edition.
- Following the revelations, the investigation sparked several impacts, from a call for a public hearing in Brazil’s lower house of Congress, a citation in a lawsuit to ban shark meat from federal procurements, to an industry debate questioning the harms of shark meat consumption.

Mekong sand mining risks collapse of SE Asia’s largest freshwater lake, study finds
- Surging demand for sand used in construction projects poses an existential threat to Southeast Asia’s largest freshwater lake, new research indicates.
- The seasonal expansion and contraction of Cambodia’s Tonle Sap Lake is often referred to as the Mekong River’s “heartbeat” due to its fundamental role in sustaining ecosystems and human lives across the region.
- Sand mining in the Mekong River, particularly in Cambodia and Vietnam, has deepened the river channel, effectively halving wet season flows into Tonle Sap Lake between 1998 and 2018, the study found.
- The stark findings underscore the severity of sand mining impacts, adding urgency to calls for improved and coordinated river governance throughout the Mekong Basin.

A flood of logs post-Cyclone Senyar leaves Padang fishers out of work
- Flash floods in late November swept timber and mud from upstream forests into coastal waters around Padang, blocking access to the sea and cutting off the livelihoods of hundreds of fishers.
- Fishers say massive floating logs have damaged boats and halted daily incomes, forcing many families to rely on credit to meet basic needs.
- Marine scientists warn that suspended sediment and decaying timber threaten coastal ecosystems by blocking sunlight, disrupting food chains and degrading water quality.
- Environmental groups link the disaster to illegal logging and weak forest governance upstream, calling for stronger law enforcement, national disaster status and urgent government action.

Drug gangs in Ecuador and Peru also involved in shark fin trafficking: Report
Narcotrafficking gangs operating out of Manabí, a coastal province of Ecuador, are also involved in trafficking shark fins alongside their drug operations, according to a recent investigation by Ecuadorian news agency Código Vidrio. Evidence from wiretaps, surveillance and raids seen by Código Vidrio reporters suggests that gangs are capturing and finning sharks and transporting the […]
The lab-in-a-backpack busting illegal shark fins: Interview with Diego Cardeñosa
- Diego Cardeñosa chose lab-based DNA research over fieldwork during his Ph.D. on sharks, betting it could deliver greater conservation impact despite being less glamorous.
- He developed a portable, rapid DNA test — like the kits used during the COVID-19 pandemic — that allows inspectors to identify shark species from fins on the spot, solving a key bottleneck that let illegal shipments slip through.
- The tool has evolved from identifying a handful of protected species to distinguishing among more than 80 sharks and rays in a single test.
- Now deployed across multiple countries, the relatively low-cost kit is expanding through grant support, with plans to adapt the technology to other trafficked wildlife beyond sharks.

Pacific fisheries summit gives a boost to albacore & seabirds
- The Western and Central Pacific Fisheries Commission (WCPFC), a multilateral body that sets fishing rules for an area that covers nearly 20% of the planet, held its annual meeting Dec. 1-5 in Manila, the Philippines.
- The parties adopted a harvest strategy for South Pacific albacore (Thunnus alalunga) that will set near-automatic catch limits based on scientific advice, considered a best practice in fisheries management. Conservationists celebrated the move.
- The parties also adopted a measure that aims to keep seabirds from drowning on industrial fishing lines.
- They didn’t adopt any new rules on the ship-to-ship transfer of fish and other goods at sea, a practice known as transshipment that’s been linked to illegal fishing and other illicit activity.

Brazilian government serves shark to infants, prisoners and more: How Mongabay broke the story
Mongabay senior editor Philip Jacobson joins Mongabay’s podcast to discuss a two-part investigation published this year in collaboration with the Pulitzer Center about how state governments in Brazil have been procuring shark meat — which is high in mercury and arsenic — served to potentially millions of schoolchildren and thousands of public institutions. With Mongabay’s […]
Seafloor survey in Cambodia finds simple anti-trawling blocks help seagrass recover
- A recent study provides the first large-scale map of Cambodia’s coastal habitats and reports early seagrass recovery near anti-trawling structures in the Kep Marine Fisheries Management Area.
- Surveys across 62,146 hectares (153,566 acres) show a 39% loss of seagrass cover in Kampot province over the past decade.
- The study doesn’t examine potential impacts from the planned $1.7 billion Funan Techo Canal, which is set to meet the sea about 2.5 kilometers (1.6 miles) away from the Kep Marine Fisheries Management Area.

Artisanal fishers in Liberia question benefits of new tracking devices from government
- The Liberian government earlier this year distributed 400 automatic identification system (AIS) transponders to small-scale fishers in the counties of Grand Cape Mount, Grand Bassa, Margibi and Montserrado.
- The devices transmit a vessel’s position and speed via radio signals, and Liberian authorities say they hope it will help in speeding up responses to vessels that are in distress.
- However, many small-scale fishers appear reluctant to adopt the new device, with some saying they would prefer GPS-equipped devices that let them track their own location.
- The Liberia Artisanal Fishermen Association (LAFA), an advocacy group, blames the low adoption rate on the inadequate involvement of fishers during the design and rollout of the project.

Study finds more ‘laggards’ than ‘leaders’ among high seas fisheries managers
- A new paper suggests that regional fisheries management organizations (RFMOs) haven’t done a very good job setting up systems to conserve fish stocks and broader ecosystems.
- The paper questions RFMOs’ readiness for a coming new era of marine governance, with the high seas treaty set to take effect in January.
- The authors rated 16 RFMOs based on 100 management-related questions, such as “Are there consequences for violations of conservation measures …?” and used the answers to help identify “leaders” and “laggards.” The average rating was 45.5 out of 100.
- They also determined that on average, more than half of RFMOs’ target stocks are overexploited or collapsed, reinforcing previous research.

Global manta and devil ray deaths far exceed earlier estimates: Study
- A new global assessment estimates more than 259,000 manta and devil rays (genus Mobula) die in fisheries each year, far exceeding previous figures, with researchers warning that the true toll is likely higher due to major data gaps.
- Small-scale fisheries account for 87% of global mortality, with India, Indonesia, Sri Lanka, Myanmar and Peru responsible for most mobulid deaths .
- The study documents steep, long-term declines, including in Mozambique, the Philippines and the eastern Pacific Ocean. Yet many losses came to light only recently due to late adoption of monitoring and weak reporting.
- Researchers say the recent uplisting of all mobulid species to CITES Appendix I, which bans international commercial trade, is a key step, but note that national-level protections, improved data reporting, gear reforms, and better spatial management are needed to reduce mortality.

As fish catches fall and seas rise, Douala’s residents join efforts to restore mangroves
- Cameroon’s coastal fisheries are in decline, leaving fishers with dwindling catches — a crisis linked directly to the depletion of the country’s mangroves, experts say, which are breeding grounds for fish.
- The expansion of urban settlements, conversion of coastal land for agriculture, and sand extraction drives mangrove loss in Cameroon; another key driver is the use of mangrove wood for smoking fish.
- The Cameroon government and NGOs have set themselves an ambitious goal of restoring 1,000 hectares (nearly 2,500 acres) of mangrove forests by 2050.
- A key strategy involves engaging local communities in the replanting process and providing alternative livelihoods, such as urban farming and beekeeping, to reduce dependence on mangrove wood.

South Greenlanders speak out on rare earths interests
QAQORTOQ, Greenland – South Greenland is increasingly targeted for new mining projects as global demand for critical minerals continues to grow. These developments promise jobs, revenue and the prospect of greater economic independence. Yet for small-scale fishermen like Jens Peter, the expansion of mining into coastal zones presents real risks, including potential restrictions on access […]
With a target on their bellies, can California’s sturgeon survive?
- California’s green sturgeon and white sturgeon face numerous threats from dams, harmful algal blooms and overfishing.
- White sturgeon are highly prized for their eggs, which are made into caviar.
- Their numbers have dropped so precipitously that they’re now being considered for protection under the California Endangered Species Act.
- The state banned commercial sturgeon fishing in 1954, but the amount of poaching and caviar trafficking is unknown, and there have been cases linked to criminal networks involved in other illegal activities.

‘Myopic’ fisheries managers toy with a new ‘tragedy of the commons’ (commentary)
- There are many examples of “tragedies of the commons,” whether in the atmosphere as a result of carbon dioxide pollution, or in the oceans because of marine plastics. But arguably the largest in the world is caused by overfishing, a new op-ed argues.
- The general absence of effective fisheries regulations that ensure the conservation of healthy fish populations endangers whole oceans and the billions of people who depend upon fish for their livelihoods.
- “Currently, fisheries ministers are myopically obsessed with the pain the industry always claims it would suffer next year if the right conservation policies were adopted. They should look instead at how long we have been getting it wrong, and how quickly things could be turned round,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

South Africa withdraws abalone listing even as illegal trade threatens species
- Ahead of the recent CITES summit to hash out wildlife trade regulations, South Africa was expected to table a proposal that would have tightened the legal trade in South African abalone, a shellfish in high demand in East Asia.
- The proposal was aimed at protecting an endangered species that’s been severely depleted by a massive illegal trade driven largely by organized crime.
- However, the South African delegation withdrew the proposal at the last minute, amid ongoing tensions in the country between conservationists, abalone farmers and coastal communities dependent on income from the illegal trade.
- A recent report by wildlife trade NGO TRAFFIC calls for coordinated international action to curb the illegal trade, including a CITES listing.

Healthy oceans are a human right (commentary)
- In 2022, the United Nations affirmed the basic human right to a clean, healthy and sustainable environment.
- The idea is straightforward: people’s fundamental human rights to health, food, security and even life rely on a healthy environment.
- But we are still far from ensuring that these rights are protected for the coastal communities living with the consequences of ocean decline every day, a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Indigenous knowledge and science join forces to save the choro mussel in Chile
- In southern Chile’s Huellelhue River estuary, three Mapuche Huilliche communities are leading efforts to restore the natural beds of the choro mussel through a participatory governance model that brings together ancestral knowledge, science and education.
- Intensive harvesting during the 1990s led to the collapse of this mollusk, disrupting local ecosystems and the livelihoods of coastal communities.
- After confirming the mussel’s critical state, a total harvesting ban was declared in 2019; the communities formally requested that the Undersecretariat of Fisheries and Aquaculture extend it to 2026.
- Thanks to the ban, the mussel population is now showing clear signs of recovery, while Indigenous communities and experts implement a sustainable management plan and a laboratory-based repopulation program.

45 more shark species up for CITES protections; tight vote expected
- Twenty-nine houndsharks and 16 gulper sharks are up for listing on CITES Appendix II at the wildlife trade regulator’s summit in Uzbekistan this week.
- Conservationists expect the vote to be close, with critics saying “lookalike” species shouldn’t face trade restrictions. Proponents argue it’s necessary given the lack of knowledge among customs officials.
- Houndsharks are widely consumed for their meat in Europe and Australia, while gulpers are hunted for their liver oil.

How community custody empowered Ecuador’s crab catchers and revived its mangroves
- Under agreements for sustainable use and protection, Ecuador’s environment ministry has granted concessions for 98,000 hectares (about 242,000 acres) of mangrove forests to artisanal fishers in the Gulf of Guayaquil.
- The fishers can catch crabs to sell, but are committed to the protection of this valuable ecosystem, imposing closed seasons twice a year and refraining from catching female and juvenile crabs.
- The concessions represent 62% of the total area of mangrove forests in Ecuador, of which 80% are located in the Gulf of Guayaquil.
- This system has allowed for the conservation of mangroves for 26 years and has been shown to be effective in protecting this type of forest, which is capable of retaining up to five times more carbon than other tropical forests.

The roughed-up roughy fish (cartoon)
The orange roughy may be among the oldest living deep-sea fish in the world, with a lifespan of up to 250 years. But bottom trawling practices in Australia and New Zealand might have already decimated their slow-breeding populations beyond recovery.
Toxic runoff from politically linked gold mine poisons Cambodian rivers, communities
- Communities along Cambodia’s O’Ta Bouk River are experiencing severe water contamination, skin ailments and the collapse of fish stocks, which they blame on an unregulated gold mine operating upstream inside Virachey National Park.
- Satellite imagery analysis shows more than 2,400 mining sites across Mekong river basins — including alluvial and heap-leach gold mines — whose toxic runoff threatens rivers, floodplains, farmland, wildlife and millions of downstream residents.
- Communities downstream of the gold mine told Mongabay that authorities have failed to act on the problem, despite multiple indicators suggesting the pollution of the river is linked to mining activity.
- Documents show that a company linked to tycoon Try Pheap controlled the mining area at the time when communities reported pollution that’s left them fearful for their health, livelihoods and food security.

For sharks on the brink of extinction, CITES Appendix II isn’t protective enough (commentary)
- Listing shark species under CITES Appendix II, which allows for well-monitored sustainable trade, has helped to save some sharks from extinction. But some species are so threatened that they need to be listed on Appendix I, which bans all trade.
- New research has revealed that many fins belonging to sharks protected by Appendix II are still being sold in large numbers in Hong Kong, one of the biggest markets, supporting the need for action on Appendix I listings for some species at the CITES COP20 meeting that commences next week in the Uzbek city of Samarkand.
- “Governments meeting at COP20 in Uzbekistan should follow the science, support these proposals, and help save these sharks and rays from the brink of extinction. It’s the only way to give these species a fighting chance at survival,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Study finds important Nassau grouper spawning site in Belize near collapse
- The Nassau grouper (Epinephelus striatus), a large-bodied top predator, was once the most abundant and commercially important fish in the Caribbean.
- Each winter, the groupers gather en masse at special places to breed, but many of these so-called fish spawning aggregation sites have been dwindling or succumbing entirely to overfishing.
- A new study looked at an important spawning site at Northeast Point on Glover’s Reef Atoll in Belize and found that the number of Nassau groupers attending the annual gathering declined by 85% over the past two decades and is now “on a trajectory towards local extirpation.”
- It attributes the decline to the government’s limited capacity to enforce regulations aimed at protecting the groupers from fishing at the remote site.

Trade in marine fish for aquariums includes threatened species, lacks oversight: Study
- A new study of major U.S.-based online retailers of marine fish bound for aquariums found that nearly 90% of traded species are sourced exclusively from the wild, including a number of threatened species, and that the trade is poorly tracked.
- The study raises concerns about the ecological impact of the trade on marine ecosystems, including around coral reefs, in countries such as Indonesia and the Philippines, where the fish are caught.
- Experts called for more work to develop sustainable fisheries and aquaculture in coastal communities in the Global South, and for building consumer awareness and establishing eco-certification schemes.

Pakistan declares its third marine protected area, but has a long way to go
- In September, Pakistan declared its third marine protected area, around Miani Hor Lagoon on the country’s central coast.
- The biodiversity-rich lagoon hosts a lush mangrove forest, numerous bird species and threatened marine mammals.
- Conservationists welcomed the new marine protected area as a baby step toward meeting the country’s so-called 30×30 commitment to protect 30% of its land and sea by 2030. However, the new addition puts Pakistan’s total protected marine area at just 0.23% of its marine and coastal jurisdiction.
- The scope of protections for the new protected area remains to be determined. Local people expressed concern that restrictions could upend the livelihoods of the local community, which depends on the lagoon and mangroves and already lacks basic necessities.

West Africa’s oceans get $68 million lifeline amid fisheries decline
A coalition of international organizations has launched the West Africa Sustainable Ocean Programme to tackle the region’s deepening fisheries decline. Led by the IUCN (the global wildlife conservation authority), Expertise France and the Fisheries Committee for the West Central Gulf of Guinea (FCWC), the WASOP initiative aims to curb illegal fishing, restore marine ecosystems, and […]
Mongabay launches dedicated Oceans Desk to expand global reporting on marine ecosystems
- Mongabay has launched a dedicated Oceans Desk composed of a global team of journalists specialized in reporting on oceans, fisheries and marine conservation.
- The desk, which includes editors, reporters and program directors from across Mongabay’s newsroom, marks a strategic shift to deepen our coverage of marine ecosystems.
- Mongabay’s ocean reporting has already led to real-world impacts, including exposing corruption in Chilean marine protected area management and informing international sanctions on a Chinese fishing company related to illegal shark finning and abusive labor practices.
- The Oceans Desk marks a milestone in Mongabay’s growth over more than two decades and strengthens the organization’s ability to inform, inspire and sustain effective action on marine conservation worldwide.

Embrace ‘blue’ foods as a climate strategy at COP30, fisheries ministers say (commentary)
- The “blue” or aquatic foods sector is often overlooked as a climate strategy, despite its potential to help meet demand for protein with a smaller environmental footprint, fisheries ministers from Brazil and Portugal argue in a new op-ed at Mongabay.
- Many blue foods generate minimal carbon emissions and use modest amounts of feed, land and freshwater, and their increased consumption could cut annual global CO₂ emissions by a gigaton or more.
- “Brazil and Portugal stand ready to champion global efforts to harness and safeguard blue foods for climate mitigation and adaptation strategies, generating multiple benefits across sustainable development goals. We call on more countries to implement measures across the blue food sector that strengthen food security and climate strategies at COP30 and beyond,” the authors write.

‘Not good’: Ocean losing its greenness, threatening food webs
- The ocean is losing its greenness, a new study has found: Global chlorophyll concentration, a proxy for phytoplankton biomass, declined over the past two decades, especially in coastal areas.
- Phytoplankton are the base of the marine food web, supporting fisheries and broader ecosystems, so their decline could have far-reaching implications, experts say.
- The phytoplankton decline could hurt coastal communities that live off the sea, and affect the ocean’s ability to act as a carbon sink, the authors say.

Scientists call for stronger action to save Indonesia’s vanishing seagrass meadows
- Marine experts at the Indonesian Seagrass Symposium in Bali warned that seagrass ecosystems — vital for carbon storage, biodiversity and coastal protection — remain largely overlooked in national policy and conservation efforts.
- Seagrass coverage in Indonesia has fallen from around 30,000 km2 in 1994 to about 8,000 km2 today, with losses driven by pollution, mining, coastal development and sedimentation that reduces water clarity and habitat quality.
- Indonesia holds some of the world’s most extensive remaining seagrass meadows, estimated to store more than 30 million metric tons of CO2, making their protection crucial for both national and global climate goals.
- Scientists and conservation leaders urged stronger data collection, funding and institutional capacity to support restoration, monitoring and community participation, positioning Indonesia as a potential leader in seagrass conservation.

Antarctic conservation summit closes with stalemate on MPAs & krill fishing rules
- The annual meeting of the international body responsible for the conservation of Southern Ocean marine ecosystems concluded Friday with no progress on two contentious issues before it: the creation of new marine protected areas and the strengthening of regulations governing the fishery for krill (Euphausia superba), a species on which numerous iconic species of Antarctic wildlife depend.
- This year’s annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) was particularly tense, due to a clash between two occasionally overlapping groups of countries: on one side, those working to establish new marine protected areas (MPAs), and on the other, those more focused on increasing krill fishing.
- CCAMLR has considered proposals to establish three large MPAs annually for years but has failed to pass them under its consensus-based decision-making process. This year was the same, due to vetoes of MPA proposals by Russia and China.
- The combination of a lack of will to reinstate previously agreed regulations governing the krill fishery and a new push to drastically increase the krill harvest suggests a change in direction at CCAMLR toward more permissive fishing.

Thai agri giant CPF sues activist over claims linking it to invasive fish outbreak
- The head of a Thai NGO focused on agricultural monitoring and food sovereignty is being sued by agribusiness giant Charoen Pokphand Foods (CPF) for alleging the firm is linked to the outbreak of an invasive fish species in Thailand’s waterways.
- The lawsuit has been slammed as a SLAPP (strategic lawsuit against public participation) and a tactic to divert attention away from containing the outbreak and identifying the source and parties responsible.
- The blackchin tilapia has spread to at least 19 provinces, where it outcompetes wild and commercially viable aquatic species, disturbing ecosystems and devastating farmers’ livelihoods.
- The case comes as Thailand awaits public hearing of new anti-SLAPP regulations aimed at curbing judicial harassment.

Chaos on Cambodia’s Coast
Along Cambodia’s rapidly transforming coastline, illegal trawling, elite-backed development, and weak enforcement are driving marine ecosystems and fishing communities to the brink. This 2024 series investigates the institutional breakdown behind the country’s marine crisis, from ineffective patrols in protected areas to billion-dollar land deals displacing small-scale fishers. It examines the competing interests reshaping Cambodia’s coast, […]
Belize’s blue reputation vs. reef reality: Marine conservation wins, and what’s missing (commentary)
- For over a year, journalists from Mongabay and Mongabay Latam have been digging into issues related to the Mesoamerican Reef, the Western Hemisphere’s largest barrier reef system, which runs from Mexico’s Yucatán through Belize and Guatemala to Honduras.
- As part of that effort, which involves exploring both problems and solutions, Mongabay founder Rhett Ayers Butler spoke to experts and reviewed many reports, scientific papers, and stories.
- With its early leadership and significant funding, Belize has emerged as a linchpin in Mesoamerican Reef conservation and fisheries management. This summary brings together what various experts have said—highlighting gaps, issues, and actionable recommendations as they relate to Belize.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

A fisheries observer disappeared at sea. His family still waits for answers
- Samuel Abayateye, a 38-year-old fisheries observer from Ghana, vanished from the Marine 707 in 2023 while monitoring tuna catches. Six weeks later, a mutilated body washed ashore near his home, but authorities have never released DNA results or an autopsy report.
- Fisheries observers like Abayateye work alone at sea to record catches and report illegal practices, often among the very crews they monitor. Their role is vital to enforcing fishing laws but exposes them to isolation, threats, and violence.
- His disappearance echoes that of Emmanuel Essien, another observer who vanished after documenting illegal fishing on a Chinese-owned trawler. Both cases remain unsolved, part of a global pattern in which at least one observer dies or disappears each year.
- Ghana’s government still mandates observers on every industrial vessel, yet offers them little protection—no insurance, secure contracts, or emergency communication. Abayateye’s family continues to seek answers, while his body, if it is his, remains unburied.

Norway’s proposal to double krill harvests raises tension at Antarctic conservation summit
- Norway has proposed almost doubling the catch limit for krill in the Southern Ocean, a proposal that has exacerbated tensions at the annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) in Australia. Conservationists have expressed concern because the continent’s iconic wildlife depend on krill for sustenance.
- The CEO of Aker BioMarine, a Norwegian company that dominates the Southern Ocean krill catch, said it has been working with CCAMLR member countries to advance the proposal as well as create a marine protected area around the Antarctic Peninsula.
- Chinese and Russian delegates have voted for years to veto new marine protected areas in the Southern Ocean.
- Russia came into the spotlight at this year’s meeting following its arrest of Leonid Pshenychnov, a researcher at the Ukrainian Institute of Fisheries, Marine Ecology and Oceanography and a longtime member of the Ukrainian delegation to CCAMLR.

UK fish stocks in trouble as catch limits exceed scientific advice: Report
Nearly half of the United Kingdom’s most commercially valuable fish populations are either overexploited, critically low or both, according to a new report warning that the government continues to set catch limits above scientific advice. The report, “Deep Decline,” by conservation nonprofit Oceana UK, found that 17 of 105 U.K. fish stocks are both overfished […]
Report finds dangerous mercury levels, highlights mislabeling in shark meat sold in EU
- Nearly a third of shark meat samples taken from products sold in Europe contained dangerously high methylmercury levels, with all tope shark and almost a quarter of blue shark samples exceeding EU safety limits, a new study finds.
- Much shark meat is mislabeled under names like rock salmon, huss or veau de mer, leaving consumers unaware they’re eating shark and could be ingesting a potent neurotoxin.
- Methylmercury can’t be cooked out, builds up in human tissue and can cause lasting neurological harm. Meanwhile, shark populations are declining, threatening marine ecosystem stability.
- The study’s authors urge stricter labeling laws, tighter food monitoring and consumer education, arguing that eating apex predators is both ecologically and medically unsustainable.

Two years later, no closure for family of missing Ghanaian fisheries observer
- Samuel Abayateye, a father of two, tasked with monitoring a Ghana-flagged tuna-fishing vessel, was reported missing on Oct. 30, 2023.
- Two years on, his family still hasn’t receive any formal updates from the Ghanaian police or any other agency about what happened to Abayateye.
- The authorities haven’t shared the results of a DNA test on a body found a few weeks after Abayateye went missing, which the family believe was his.
- Mongabay made repeated attempts to contact the police, but didn’t receive a response about the case.

Rare earth mining expands into Laos, threatening entire Mekong River
- Satellite data show at least 27 new rare earth mines have opened across Laos since 2022, mostly in protected areas and many within the Mekong River Basin, raising transboundary pollution risks for Vietnam and the wider Mekong system.
- Though rare earth mining is banned in Laos, operations — often funded by Chinese investors — continue under local-level permissions, reflecting weak oversight and growing Chinese influence as Laos seeks to boost its resource exports.
- Past incidents of chemical spills and fish die-offs have already harmed communities in northern and northeastern Laos, yet limited press freedom and civic space mean contamination and environmental impacts remain largely unreported and unmonitored.
- Experts warn that a rare earth mining boom could have severe ecological and social consequences, including deforestation, loss of livelihoods, and toxic pollution, with local communities powerless against unregulated mining backed by local elites and foreign capital.

Global conservation body takes first step to protect ocean’s twilight zone
- Delegates at the IUCN World Conservation Congress in Abu Dhabi voted to adopt a motion urging precautionary measures to protect the ocean’s mesopelagic zone.
- The nonbinding motion calls for prospective activities such as fishing in the mesopelagic zone, deep-sea mining and geoengineering to be guided by the best available science and approached with caution.
- Both conservationists and industry representatives expressed support for the motion, highlighting the mesopelagic zone’s ecological importance and potential as a sustainable resource.

Why is protecting this Honduran lagoon so dangerous?
LAGUNA DE LOS MICOS, Honduras — Tension swirls around the Laguna de los Micos in northern Honduras, which is a critical marine ecosystem surrounded by mangroves and serving as a home and nursery for many species of coral reef fish. The communities living around the lagoon have voluntarily agreed to suspend fishing for two months […]
Booming sea otters and fading shellfish spark values clash in Alaska
- In Alaska, a state brimming with iconic wildlife — from grizzly bears to king salmon, humpback whales to harbor seals — the charismatic, densely coated sea otter stands out as perhaps the state’s most hotly debated, controversial species.
- Sea otters were nearly hunted into extinction a century ago for their luxurious pelts. But they have been surging in population in the Gulf of Alaska, bringing both benefits to nearshore ecosystems and drawbacks to the shellfish economy (due to the otters’ voracious caloric needs).
- Described by commercial shellfish harvesters and Native Alaskans as pillagers of clams and crabs, sea otters are seen by many marine biologists as having positive impacts on kelp forests — important for biodiversity and carbon storage. Scientists stress that shellfish declines are complex, with sea otters being just one among multiple causes.
- Native Alaskans are the only people given free rein to hunt sea otters. But long-standing federal regulations stipulating who qualifies as Native Alaskan make it illegal for most to manage their own waters. Tribes are fighting for regulatory changes that would enable them to hunt and help balance booming sea otter populations.

Ghost nets entangling turtles, marine life in Sri Lanka’s waters
In Sri Lankan waters, there’s a growing problem of ghost nets that are entangling sea turtles, fish, dolphins and seabirds, reports contributor Malaka Rodrigo for Mongabay. “Ghost nets” are fishing gear that have either been abandoned, lost or discarded into the sea. As these drift with the ocean currents, they continue to trap marine animals […]
Rare dugong calf sighting in Alor spotlights seagrass & marine mammal conservation
- A rare sighting of a dugong calf in Alor, Indonesia, has renewed focus on the health of the region’s seagrass ecosystem and the species’ fragile future.
- Conservationists say the presence of multiple dugongs indicates a thriving habitat, but threats from tourism, habitat loss and limited population data remain pressing concerns.
- Authorities and experts are pushing for stronger monitoring and coordinated conservation strategies under a forthcoming national action plan.

South African sharks threatened by fisheries, weak enforcement
- The only permit holder in South Africa’s demersal shark longline fishery has been reported breaching permit regulations, raising questions about the sustainability of the fishery.
- The fishery targets critically endangered and endangered shark species with no catch limits in place to prevent overfishing.
- Target species are already depleted, according to scientific assessments, while little is known about bycatch of other protected and endangered species.

Indonesia falls short in bid to increase its share of southern bluefin tuna catch
- The Commission for the Conservation of Southern Bluefin Tuna (CCSBT), a multilateral body that manages the stock of southern bluefin tuna, held its annual meeting Oct. 6-9 in Bali, Indonesia.
- Indonesia pushed for a larger share of the global catch, which is currently dominated by Australia and Japan, but CCSBT members instead kept each nation’s share unchanged.
- Members also agreed to once again fully fund a key stock monitoring program, and to set up a future meeting for discussion of seabird protection in the fishery, amid criticism from conservationists that the commission hasn’t done enough to protect seabirds.

Abandoning Antarctic krill management measure threatens conservation progress (commentary)
- Until 2024, spatial limits across four sub-areas of the Antarctic Peninsula region had reduced the risk of concentrated fishing in areas preferred by whales, seals and penguins.
- The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) had taken an ecosystem-based approach, recognizing that effects of fishing can ripple through ecosystems; but with the recent lapse of its Conservation Measure 51-07, ships can now concentrate their fishing efforts in key wildlife foraging hotspots.
- This October, as delegates gather to discuss CCAMLR priorities, the authors of a new commentary argue that, “At stake is more than a fishing rule, but also the commitment to manage fisheries proactively, rather than reactively.”
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Global treaty to end subsidies for destructive fishing takes effect
A landmark global treaty to curb billions of dollars in government subsidies for overfishing took effect on Sept. 15, Mongabay contributor Elizabeth Fitt reported. The agreement marks the first time the World Trade Organization (WTO) has approved an environmental sustainability agreement in its 30-year history. The deal came into effect after Brazil, Kenya, Tonga and […]
Cameroon inaugurates controversial dam despite local dissent
- The inauguration of Cameroon’s Nachtigal dam has boosted the country’s electricity supply.
- The dam’s construction has also led to loss of livelihoods for fishers and sand miners on the Sanaga River around the dam site.
- In 2022, these workers received compensation from the dam, but as the full dimensions of their losses emerge, they say this was inadequate.

A protected mangrove forest stands strong as Metro Manila’s last coastal frontier
- A Ramsar site described as the Philippine capital region’s last remaining functional wetland, Las Piñas-Parañaque Wetland Park is a vital sanctuary for more than 160 local and migratory birds.
- The wetland also serves as a haven for fish reproduction, bolstering regional fisheries, and serves as a buffer zone during storms.
- In March, the agency responsible for overseeing investments in large-scale reclamation projects put out a call for “lease or joint venture” proposals for the site.
- After facing public backlash, the agency quietly deleted the call, saying it is aware of the site’s ecological importance and does not plan reclamation projects within the park.

Octopus farming is a dangerous detour for marine conservation (commentary)
- Proponents of octopus farming claim it can reduce fishing pressure on wild octopus populations by supplying the seafood industry, and even suggest that these efforts could contribute to restocking wild populations in the future.
- In reality, they have a poor feed conversion rate, requiring a large amount of wild-caught marine protein to produce a relatively small amount of octopus, which risks exacerbating, rather than easing, pressure on wild fish populations and marine ecosystems that depend on them, the author of a new op-ed argues.
- “Octopus farming is a dead end masquerading as a solution. It does not address the root causes of wild population declines — it compounds them. The global community must resist the temptation to exploit another wild species under the guise of sustainability,” the author writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

UK rejects total ban on bottom trawling in offshore marine protected areas
The U.K. government has rejected calls to fully ban bottom trawling in its offshore marine protected areas, despite evidence that the fishing practice tears up seabed habitats and releases large amounts of carbon. Bottom trawling involves dragging weighted nets across the seafloor, often crushing coral reefs and sponges while stirring up sediments. The huge nets […]
Indonesia eyes seagrass zoning for blue carbon; experts urge community benefits
- Indonesia is moving to designate 17 seagrass habitats as national strategic areas for blue carbon, a plan that promises climate and community benefits but raises concerns over safeguards.
- The fisheries ministry says the zoning will help cut emissions, protect marine ecosystems and boost coastal livelihoods, with seagrass storing carbon far more effectively than rainforests.
- Experts welcome the initiative but warn it must avoid privatization, ensure fair benefit-sharing and guarantee transparent governance to prevent conflicts and elite capture.
- With Indonesia holding 11.5% of the world’s seagrass meadows, scientists stress the urgency of protection as the ecosystems vanish globally at alarming rates.

Turning a stream into a river: Inside India’s Yettinaholé diversion project
- In Karnataka’s Western Ghats, a biodiversity hotspot, a river diversion project is bringing long-term changes to local villages — and the environment.
- The Yettinaholé Integrated Drinking Water Supply Project aims to divert 24 TMC of stormwater from the Yettinahalla and other nearby streams to several dry districts hundreds of kilometers away.
- Village life is also undergoing a series of development changes — as well as an uptick in conflicts with elephants coming from the nearby forests; meanwhile, local fishers wonder how many of the streams they rely on will become part of the diversion project, fearing for the future of their livelihoods.

Illegal fishing threatens unique marine ecosystem in Peru
- Park rangers who patrol Illescas National Reserve often confront fishers who use chinchorros, a type of fishing net that is banned in Peru.
- The reserve is designated solely as a terrestrial protected area, which often limits the park rangers’ ability to act, as the marine area is outside their jurisdiction.
- Conservationists warn of the urgent need to safeguard this important marine area and its rich biodiversity.

How we probed a maze of websites to tally Brazilian government shark meat orders
- A recent Mongabay investigation found widespread government purchases of shark meat in Brazil to serve in thousands of public institutions.
- The series has generated public debate, with a lawmaker calling for a parliamentary hearing to discuss the findings.
- Here, Mongabay’s Philip Jacobson and the Pulitzer Center’s Kuang Keng Kuek Ser explain how we built a database of shark meat procurements.

As Sri Lanka struggles with ghost nets, volunteer youth lead seabed cleanup
- Abandoned, lost or discarded fishing gear, commonly called “ghost nets,” continue to trap and kill marine animals such as sea turtles, dolphins and whales, long after these nets being discarded in Sri Lankan waters.
- As this fishing gear can travel long distances via winds and ocean currents before sinking, it accumulates along shorelines or converges in large plastic patches in the oceans, becoming a transboundary issue.
- Volunteer initiatives such as The Pearl Protectors are diving to remove ghost nets, successfully recovering tens of hundreds of kilograms of discarded fishing gear from coral reefs and seagrass beds.
- While recycling efforts continue, a Sri Lankan designer has pioneered an innovative upcycling approach, transforming ghost fishing nets into fashion items — merging marine conservation with sustainable creativity to raise awareness of ocean pollution.

From Chile to Greece, ‘ghost gear’ from fish farms haunts the seas
- Studies and NGOs have documented lost or abandoned gear from open-net aquaculture operations in coastal areas across cold and temperate latitudes, where fish farming in the sea expanded rapidly in the 1980s and ’90s.
- In Chile, Greece and Canada, for example, observers have reported finding disused buoys, sections of rusting platforms, expanded polystyrene, net cages and other debris washed up on shorelines, or sunk in the water.
- Guidelines published by the Global Ghost Gear Initiative (GGGI), a worldwide alliance of groups seeking solutions to fishing gear pollution, say neglected or mismanaged aquaculture gear can disperse in the environment and break down into debris of various sizes, posing risks such as entrapping marine life, damaging habitats or contributing to microplastic pollution.
- Some industry groups say current regulations and practices suffice to prevent ongoing pollution and they are working to resolve legacy contamination.

Alaskan rivers turn orange as permafrost thaws, threatening fish and communities
- A new study found that 75 streams in Alaska’s Brooks Range have turned orange due to thawing permafrost, which releases metals like iron, aluminum and cadmium that exceed U.S. Environmental Protection Agency safety thresholds for aquatic life.
- The contamination threatens fish populations, with aluminum concentrations at one location reaching nearly five times the safe limit, and the study suggests this may help explain recent crashes in chum salmon returns that Indigenous communities depend on for food and income.
- The pollution flows hundreds of miles downstream to coastal communities like Kivalina, where residents who rely on traditional fishing face threats to food security as some tributaries of rivers like the Wulik have begun turning orange.
- Scientists warn that this climate change impact is irreversible and spreading across the Arctic, with no cleanup options, as these remote watersheds contain hundreds of contamination sources.

Indigenous fishers lead science-backed conservation of Colombia’s wetlands
- A community-based monitoring project is helping protect the rich diversity of freshwater fish species in the Ramsar-listed wetlands in the Colombian Amazon.
- By combining ancestral knowledge with scientific tools, Indigenous Amazonian leaders say their communities are strengthening their connection to their territory.
- Community monitoring and training efforts have helped inform fishing regulations to better protect ecosystems and ensure the sustainability of local populations’ livelihoods.

‘Super big deal’: High seas treaty reaches enough ratifications to become law
- The agreement on marine biodiversity of areas beyond national jurisdiction, also known as the high seas treaty, was reached in 2023 with much fanfare in marine conservation circles, partly because it sets up a system for establishing marine protected areas (MPAs) in international waters.
- On Sept. 19, Morocco became the 60th country to ratify the deal, which means it will become binding international law in January 2026.
- Experts and advocates celebrated the milestone, calling it a win for conservation and international cooperation.
- Uncertainty remains in how the treaty will interact with other regulatory regimes for fishing and mining, among other activities.

Mongabay shark investigation cited in motion to ban Brazil fin exports
Brazil’s top environment council cited a recent Mongabay investigation as it weighed a ban on shark fin exports and the use of wire leaders, a type of industrial fishing gear, within marine protected areas, Mongabay staff writer Karla Mendes reported. Brazil’s National Environmental Council, known as CONAMA, voted in favor of recommending a ban for […]
EV trial among Bali east coast fishers shows promise amid headwinds
- A social enterprise initiative to equip traditional fishing boats in east Bali with battery-powered engines has shown some encouraging responses among the trial cohort.
- More than 90% of the world’s 40 million fishers are small-scale operations working from small boats, which policymakers say are better suited to adopt electric vehicles compared with larger vessels.
- Azura Indonesia, the company manufacturing electric maritime engines, hopes new charging infrastructure will help overcome commonly cited challenges, including the need for inexpensive, frequent charging required by traditional fishers.
- The electric vehicle trial in Kusamba village was conducted under the Bali Net Zero Emissions Coalition’s energy transition work on the island of 4.5 million.

São Tomé and Príncipe commits to creating a marine protected area network
- São Tomé and Príncipe will establish eight marine protected areas (MPAs) covering 93 square kilometers (36 square miles) of coastal habitats in the Gulf of Guinea.
- The island nation aims to protect its marine environment while improving the lives of fishing communities, who rely heavily on fish for protein.
- Current challenges include the decline of pelagic fish stocks and loss of biodiversity due to indiscriminate fishing practices and climate change.
- The law designating the MPAs is expected to be enacted in September.

Pet sharks have become cool, but is owning them ethical?
- Owning a shark and keeping it in a home aquarium has become cool — and it’s no longer just the province of tech bros and celebrities.
- But experts note that most home aquariums are inadequate and can lead to stunted growth, deformities and early death.
- Yet sharks are often easy to buy, with some selling for as little as $90 online; zebra sharks (Stegostoma tigrinum), which are endangered, go for around $6,000.

24 years on, part one of WTO treaty curbing fisheries subsidies takes effect
- The first part of the WTO’s treaty banning harmful fisheries subsidies, known as Fish One, entered into force Sept. 15 after more than two decades of negotiation and three years of ratification.
- It bans subsidies for IUU fishing and exploitation of overfished stocks while requiring parties to the treaty to disclose detailed data on fleets, catches and subsidy programs.
- Yet it allows certain subsidies to persist; for instance, for fishers targeting unassessed fish stocks or “managed” overfished stocks.
- The treaty will lapse in four years if no follow-up “Fish Two” deal can be reached, but negotiations remain stalled.

Brazil weighs new measures to manage shark trade, fishing
- The Brazilian government is reviewing its legal framework for the trade in sharks, including fin exports and management of the fishery for blue sharks (Prionace glauca), the only species allowed to be caught in the country.
- At a Sept. 3 meeting, the National Environmental Council (CONAMA), a government advisory body, recommended the government ban shark fin exports and restrict the use of shark-fishing gear known as wire leaders.
- At the same meeting, the Ministry of Environment announced the suspension of an ordinance regulating blue shark fishing, including quotas, due to “increased pressure” on endangered species and flaws in monitoring and enforcement.
- The moves follow a recent Mongabay investigation revealing that government agencies sought to procure thousands of tons of shark meat for meals at public institutions including schools, hospitals and prisons. The exposé was cited at the Sept. 3 CONAMA meeting as well as in a class-action civil suit filed by conservation NGO Sea Shepherd Brasil seeking to ban federal public institutions from issuing tenders for shark meat.

Countries shorten tuna fishing closure at Pacific summit with few conservation ‘wins’
- The Inter-American Tropical Tuna Commission (IATTC), a multilateral body that manages tuna and other fish stocks in the Eastern Pacific, held its annual meeting Sept. 1-5 in Panama.
- Commission members agreed to shorten an annual fishing closure from 72 days to 64 days, which was in keeping with recommendations from the IATTC’s scientific committee.
- The members also agreed to move toward adoption, in 2026, of a long-term harvest strategy for bigeye tuna (Thunnus obesus).
- They didn’t adopt proposals to increase monitoring of longline tuna vessels and strengthen shark protection measures, due to resistance from East Asian members.

Indonesia’s giant Java seawall plan sparks criticism & calls for alternatives
- Indonesia has launched a massive new project on Java’s northern coast, framed as protection for millions of residents from worsening environmental threats.
- The plan has drawn sharp criticism from experts and activists who question its methods, costs and potential impact on vulnerable communities.
- Calls are growing for deeper public consultation and long-term solutions that go beyond quick fixes.
