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.

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 […]
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.

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.

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.

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.

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.

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.

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.

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.

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 […]
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.

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.

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.

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.”

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 […]
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.

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.

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.

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.

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.

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.

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.

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

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 […]
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.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

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.

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.

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.
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.

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.

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 […]
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.

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.

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.

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 […]
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 […]
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.

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.

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 […]
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.

‘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.

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.

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

BANJUL, Gambia (AP) — A “sea war” is brewing off the West African nation of Gambia as desperate local fishermen attack foreign commercial fishing vessels, and each other. The fight is driven by market forces and foreign seafood appetites that are far beyond their control. The Associated Press exclusively obtained video of one attack that […]
Mongabay shark meat exposé sparks call for hearing and industry debate
- A Brazilian lawmaker said he would call for a parliamentary hearing after Mongabay’s shark meat investigation.
- Experts reacted to the investigation, saying the uncovered public tenders show greater extinction risk for sharks and urging stronger global protection.
- Industry groups called Mongabay’s investigation “alarmist,” defending shark meat’s safety and sustainability, despite warnings from scientists.

Shrinking Mekong megafish underlines risks to the river, study finds
- A new study has found that the Mekong River’s largest freshwater fish are shrinking in size, with critically endangered species like the giant catfish and giant barb now averaging less than half their historical size.
- Researchers analyzed more than 397,000 samples of 257 species across Laos, Cambodia and Vietnam, finding that fish longer than 60 centimeters (2 feet) are shrinking fastest, while smaller species show little change.
- Overfishing, habitat loss, dam construction, sand mining, pollution and climate change are driving the decline, raising fears of collapse in one of the world’s most important inland fisheries.
- Scientists warn the trend mirrors global declines in large freshwater species, such as in the Amazon and Nile basins, but recent discoveries of massive fish like a 300-kg stingray show it’s not too late for recovery if urgent action is taken.

Ghana passes landmark legislation to protect artisanal fisheries
- Ghana has passed a new fisheries act which aims at strengthening the artisanal fishery sector, restoring fish stocks and tackling problems with illegal, unregulated and unreported fishing.
- A major change is the expansion of the country’s inshore exclusion zone, which will double in size, expanding from 6 to 12 nautical miles (11 to 22 kilometers) from shore.
- The law has been welcomed by artisanal fishers who have been struggling with declining pelagic fish stocks due to destructive fishing practices within the IEZ.

Indonesia’s Bajau fishers lament nickel mining’s marine pollution
For many members of the nomadic Bajau sea tribe on Indonesia’s Kabaena Island, growing up meant swimming and fishing in clear waters, just outside their homes built on stilts. However, in 2010, the water turned red, which the villagers blame on runoff from nearby nickel mining, Mongabay’s Hans Nicholas Jong reported in July. “Now, I […]
Brazil cities vow to stop buying threatened shark meat after Mongabay probe
Several government agencies in southern Brazil have said they will stop ordering angelshark meat for public meal programs, in response to a Mongabay investigation that highlighted the widespread consumption of the threatened species. Shark meat is often served in public schools, hospitals and other institutions due to its low cost and lack of bones. The […]
Killings on Kenya’s Lake Naivasha raise questions over coast guard role
- The deaths of two unlicensed fishers in Kenya’s Lake Navaisha region, allegedly at the hands of the Kenya Coast Guard Service, raise questions about tactics used to police illegal fishing.
- Jayne Kihara, the member of parliament from Naivasha, accuses the coast guard officers in the region of “killing our youth left, right and center, and drowning them when they go to look for their livelihood.”
- The coast guard’s heavily armed operations and past allegations of excessive force have left many in the region questioning whether such a force belongs in their midst.
- Mongabay reached out to the Kenya Coast Guard Service about the incidents but didn’t receive a response. The service also didn’t respond to a request for data about encounters between the coast guard and fishers that resulted in injuries or fatalities.

Brazil cities order endangered angelshark meat despite fishing ban
Government agencies in Brazil’s Rio Grande do Sul state launched public procurements for more than 200 metric tons of meat from endangered angelshark species between 2015 and 2025, a Mongabay investigation has revealed. The meat is served in public institutions, including schools.  Fishing for angelsharks is prohibited in Brazil, but its trade is legal if […]
Philippine fishers struggle as LNG ‘superhighway’ cuts through biodiversity hotspot
Fishers in the Philippines’ Batangas Bay are struggling to make ends meet and feed their families as nearby coastal areas are developed into a natural gas import hub, Mongabay contributor Nick Aspinwall reported in July. Families that have been fishing in Batangas Bay for years have been asked by local officials to leave to make […]
Indonesia’s aquafarm revamp sparks fears for fate of farmers and mangroves
- Indonesia plans to revitalize 78,000 hectares (193,000 acres) of state-owned aquaculture ponds, starting with 20,400 hectares (50,400 acres) in West Java province, aiming to boost yields, create 119,000 jobs and attract investors.
- Small-scale farmers like Warno in Karawang district, who rent and maintain ponds from the state, say they fear losing their livelihoods without compensation if the government takes over their farms.
- NGOs and experts warn the program could fuel mangrove clearing, coastal damage and privatization of coastal areas, while sidelining local communities’ rights and voices.
- Critics also raise concerns over the government’s push for more farming of saltwater tilapia, citing risks from the invasive species and an industrial aquaculture model that could reduce locals to laborers.

How will fisheries change in a hotter world? Experts share
- Fifty years from now, in 2075, global ocean temperatures are forecast to rise by between 2° and 5° Celsius (3.6° and 9° Fahrenheit). Warming is already reshaping fisheries worldwide, and even more dramatic changes are expected as fish largely move to cooler latitudes.
- These fish migrations will change ecosystem patterns and will likely have unexpected consequences even in places far from the fish themselves. They also may devastate fishing communities, both on an economic scale and a social one.
- However, there are potential solutions to avoid the most catastrophic effects for fishers and ecosystems alike, including setting aside some ecosystems as marine protected areas, changing fisheries management strategies and retraining communities to provide supplemental income.

Displaced and dispossessed, Cambodia’s ethnic Cham fishers struggle to survive
- Ethnic Cham fishers in Cambodia say they face repeated evictions from their floating homes, often timed with major events and justified as environmental protection.
- They report unequal treatment by authorities, with harsher crackdowns on their small-scale fishing while larger, illegal operations go unpunished.
- Displacement and enforcement have pushed many into poverty, with little access to alternative livelihoods or support systems.
- Experts and advocates warn that current policies risk erasing Cham culture and call for more equitable, historically informed solutions.

Revealed: Brazilian state buys endangered angelsharks for school lunches
Endangered angelsharks have been served to schoolchildren in the Brazilian state of Rio Grande do Sul for years, as well as in hospitals, clinics, shelters and other public institutions, Mongabay has found. We identified 52 tenders totaling more than 211 metric tons of “peixe anjo,” a common name for angelshark, issued by the state and city […]
Encouraging signs from a no-fishing zone in Comoros could inspire others
- Signs of improvement in fisheries arising from a small no-fishing zone in the Indian Ocean nation of Comoros could inspire the establishment of more such zones across the archipelago.
- A fishers’ group installed the first no-take zone inside a marine protected area off the island of Anjouan in 2021. The group’s president told Mongabay fishers are now encountering more fish nearer to the shore outside the zone’s bounds.
- Buoyed by the results, a local nonprofit plans to establish five no-take zones in Anjouan over the next two years, covering 425 hectares (1,050 acres) of coral reefs.
- Earlier efforts to enforce temporary fishing closures to promote octopus fisheries for export and reduce pressure on fragile coral reef ecosystems didn’t lead to the anticipated benefits.

Upmarket fish maw trade in Singapore & Malaysia includes endangered species: Study
- A new study using DNA barcoding reveals that Singapore and Malaysia’s fish maw markets include species listed as vulnerable, endangered or critically endangered, many of which are poorly monitored and sourced from unmanaged fisheries.
- Researchers identified 39 species from 503 dried maw samples, including critically endangered large yellow croakers and European eels, highlighting the scale and complexity of this high value, underregulated trade.
- Experts warn that the trade poses a growing threat to marine biodiversity, and with nearly 30% of samples coming from species lacking IUCN assessments, it makes sustainability difficult to evaluate.
- Researchers and conservationists urge governments to expand CITES protections, enhance species monitoring, educate stakeholders, and improve international coordination to prevent more marine species from being pushed toward extinction.

Rapid development, legal changes put pressure on Vietnam’s forestland
- A planned tourism and residential development on Vietnam’s Phú Quốc Island, has led to the forced relocation of 508 households and the clearing of 57.7 hectares (142.5 acres) of forest within Phú Quốc National Park.
- The project is just one of 286 development projects planned for the island. Since July 2024, authorities there have authorized the conversion of more than 180 hectares (445 acres) of forest, the majority of which is “special use” forest, meaning it is deemed to be of particular ecological or scientific importance.
- The island has seen a spike in forest conversion approvals following legal changes in 2024 that reduced central-government oversight of forest-conversion approvals, and that expanded the list of project types for which natural forest can be converted.

As gas giants move in, Philippine fishers fight for their seas and survival
- Fishing communities along the Philippines’ Verde Island Passage, a haven for marine biodiversity, say the development of a natural gas import hub in the area is leading to environmental degradation.
- Fishers say their catches have declined since a liquefied natural gas plant was built in the area a decade ago, and that they’re being turned away from remaining fishing grounds due to the ongoing construction of an LNG terminal.
- The Japan Bank for International Cooperation, a key funder of the LNG project, denies these claims, saying in a recent report that it didn’t find evidence that LNG development had led to environmental degradation or a reduction in income for local fishing communities.

That ‘fish’ on the menu? In Brazil’s schools and prisons, it’s often shark
Brazil, the world’s top importer of shark meat, is feeding much of it to preschoolers, hospital patients, military staff, public workers and more via government procurements, Mongabay has found. This influx of shark meat into public buildings is exposing infants and other vulnerable groups to high levels of heavy metals like mercury and arsenic, which […]
Batang coal plant’s seawater permit imperils marine life, fishing communities
- The Batang coal-fired power plant in Central Java, now legally permitted to use vast amounts of seawater for cooling, has raised alarms among experts over its impact on marine ecosystems and traditional fisheries.
- Since operations began, the plant has displaced fishing communities, polluted coastal waters with heated discharge and caused up to a 50% decline in shrimp catches, particularly affecting traditional fishers in Roban Barat.
- Community resistance was met with intimidation and arrests, while some residents accepted compensation from the operator, PT Bhimasena Power Indonesia, further dividing the local population.
- Critics, including Greenpeace and KIARA, say the project reflects Indonesia’s coal-centered energy policy, undermining both environmental justice and climate goals, as the country continues to expand fossil fuel use despite international pressure to shift toward renewables.

Sri Lanka hit by plastic pollution after cargo ship sinks off Indian coast
Sri Lankan authorities, locals and environmentalists say they’re deeply concerned about the possible impacts on the country’s marine ecosystem and coastal communities from the sinking of a container ship off the southern coast of India in May, Mongabay contributor Malaka Rodrigo reported in June. The Liberia-flagged ship MSC Elsa 3 sank on May 25 about […]
Evolution in overdrive as Baltic cod shrink due to fishing pressure, study shows
- The eastern Baltic cod has shrunk dramatically in size in recent decades due to rapid evolution — changes at the genetic level — caused by decades of intensive fishing, a new study says.
- Eastern Baltic cod, which are a distinct subpopulation of Atlantic cod (Gadus morhua), lost nearly half of their length and four-fifths of their weight from 1996 until 2019.
- It’s one of the first studies to show that a marine species has evolved in response to fishing pressure.
- An expert said the shrinking of the cod was “alarming,” and called on fisheries managers to work to protect fish biomass and size, given this new evidence of fisheries-induced evolution.

Conservationists raise sharks to restore reefs in waters around Thailand
- A new rewilding program aims to boost the local population of bamboo sharks in the waters of Khao Lak, Thailand.
- The species, classified as near threatened on the IUCN Red List, used to be abundant in the area, but has declined as a result of overfishing and habitat destruction.
- Since the project launched in 2018, with the support of luxury resorts in the area, it has released 200 bamboo sharks into the wild.
- A separate program that started in May 2025, is breeding leopard sharks, which are listed as endangered. They will be released in the waters off Phuket, and eventually the Gulf of Thailand.

Indonesia moves to revise sea sand export policy after court ruling
- Indonesia’s Supreme Court earlier this year struck down key parts of a 2023 regulation allowing sea sand exports, citing legal contradictions and environmental risks.
- The annulled policy had reversed a two-decade ban and faced backlash for potentially harming marine ecosystems and coastal communities.
- The government now says it’s revising the regulation, arguing that dredging can benefit ocean health and support domestic infrastructure projects.
- Critics warn the practice threatens fisheries, marine carbon stores and long-term sustainability, and call for a shift toward restoration over exploitation.

Global tracking study reveals marine megafauna hotspots lie largely unprotected
- A global study tracking nearly 13,000 marine animals representing 111 species reveals they spend 80% of their time in just 63% of their range, yet only about 5% of these high-use ocean areas are currently protected.
- The research identifies Important Marine Megafauna Areas (IMMegAs) as ecological hotspots that span national waters and the high seas, where governance and protection are often lacking.
- Findings show that the global target of protecting 30% of the ocean by 2030 is insufficient to safeguard migratory species unless paired with additional mitigation measures outside protected areas, like bycatch reduction and ship speed regulations.
- Researchers call for stronger international coordination and more dynamic, movement-informed conservation strategies to effectively protect wide-ranging ocean wildlife.

A new data hub helps small-scale fishers adapt to climate change
Roughly 40% of the global fish catch comes from small-scale fisheries. It’s one of the food production systems most vulnerable to climate change, and governments are lacking data to help fishers adapt. To help address that gap, the global research partnership CGIAR recently launched its Asia Digital Hub at WorldFish’s headquarters in Penang, Malaysia. The Hub […]
Listings of Indonesian islands renew fears of privatization for coastal communities
- Listings of Indonesian islands on a foreign real estate site have sparked concerns about privatization, prompting the government to block the site domestically and clarify that islands cannot be sold to foreign entities under national law.
- Officials said the listings were likely aimed at attracting investment, not outright sales, but critics warn such practices enable control over island and offshore areas, often displacing fishers and triggering land conflicts.
- A 2021 regulation allows foreign investors to lease small islands for up to $1,900 per km² per year, and a government portal launched in 2024 streamlines permits for islands smaller than 2,000 km², accelerating commercialization.
- Watchdogs say 254 small islands have already been privatized, often without adequate oversight, and warn that unchecked investment could jeopardize fisher livelihoods and national sovereignty over maritime territories.

Seismic noise from oil companies threatens Amazon River Mouth marine life
- As oil companies push for drilling on the Amazon coast, an underwater war silences the ocean’s most vocal creatures.
- Petrobras has been conducting surveys since 2013 using seismic airgun blasts that can destabilize marine ecosystems by interrupting essential communication in the marine food chain.
- Blasts fired every 10 seconds, reaching more than 230 decibels, disorient and kill cetaceans and other marine life that rely on sound.
- The Amazon region is emerging as a new oil frontier, driven by recent discoveries and political will to expand hydrocarbon exploration despite environmental and social risks in an area known for strong sea currents and diverse wildlife.

With coral-rich Churna Island now an MPA, Pakistan takes baby steps on ocean protection
- In September 2024, Churna Island and the sea surrounding it became Pakistan’s second designated marine protected area, home to a variety of corals and serving as a nursery for fish.
- It followed the 2017 designation of the country’s very first MPA around Astola Island, a haven for coral, birds and sea turtles to the east.
- While Pakistan’s first two MPAs are small and have yet to be fully implemented, they represent baby steps in the country’s nascent effort to protect its marine environment.
- The country still has a long way to go to protect 30% of its ocean by 2030, as mandated by the United Nations Convention on Biological Diversity.

Two coasts, one struggle for octopus fishers battling overfishing and warming waters
- In Spain and Mexico, demand for octopus is up, but octopus populations are down.
- In both countries, artisanal octopus fishers are sticking to traditional fishing techniques while joining eco-certification schemes with tighter regulations, hoping to protect not just the cephalopod population, but their own livelihoods.
- But while this may offer a lifeline to the fishers’ economies, it may only work well for the octopus populations when all fishers in an area join in, experts say — and that’s not the case in Mexico, where illegal octopus fishing is rampant.
- Moreover, factors beyond fishers’ control, like warming waters, may affect the fishers and the octopuses alike.

Illegal fishing and its consequences: the human toll of migration in Senegal
- In 2024, more than 2,000 people are believed to have died at sea while attempting to reach Spain’s Canary Islands from Senegal and the Gambia.
- According to the NGO Environmental Justice Foundation (EJF), people from Senegalese fishing communities are tempted to migrate to Europe due to declining fish stocks, owing in part to illegal fishing by European and Asian fleets.
- Illegal fishing, along with trawler fishing, are among the main drivers of this depletion of marine resources, depriving small-scale fishers in Senegal of a livelihood.
- Advocacy groups Oceana and ClientEarth have taken the Spanish government to court for failing to investigate — and, where appropriate, sanction — Spanish vessels that go dark by failing to transmit their location, and for not effectively monitoring the fishing operations of Spanish companies in West Africa.

What happens to artisanal fishers when a deep-sea fishing port comes to town?
- A new fishing port slated for completion in June will bring huge commercial vessels into the artisanal fishing community of Shimoni, Kenya.
- Local fishers fear that once the new port comes online, their fishing will become impossible in the near-shore waters they have fished for ages, and the huge vessels will disrupt local seafood markets.
- In 2023, President William Ruto promised to equip the local fishers with boats capable of fishing in the deep sea, but more than a year later, this promise has yet to be fulfilled, and local fishers say that boats the county delivered aren’t up to the task.
- Moreover, they say training will be essential to operate any deep-sea fishing vessels, along with mechanical support, and they worry they won’t be able to afford the upkeep costs.

Endangered humphead wrasse gets a lifeline from facial recognition tech
- The endangered humphead wrasse, a reef fish that swims the seas from Africa to the South Pacific, is in high demand in mainland China and Hong Kong as a luxury culinary delicacy.
- Despite harvest limits, trading regulations and fishing bans, it’s overfished and illegally traded.
- Researchers in Hong Kong have developed a new AI-based photo identification smartphone app, Saving Face, to help enforcement officers identify individual fish using their unique facial patterns with just a photo.
- Researchers say they hope the app can address both illegal laundering of humphead wrasse and mislabeling of wild-caught fish as captive-bred; its developers say it can be tweaked to identify other species that have unique markings.

As a fishing port rises in Kenya, locals see threats to sea life, livelihoods
- In Shimoni, Kenya, a new fishing port is slated to open in June.
- While the government promises local people opportunities for jobs and businesses once operations start, some residents foresee more harm than good from the port.
- Some conservation activities — including seagrass, coral and mangrove restoration projects as well as fishing, seaweed farming and tourism operations — have already suffered during the port’s construction phase, which began in 2022, local people say. They fear it may get worse once the port opens, especially if planned dredging proceeds.
- A county government official said Kwale county is monitoring the situation and pledged to mitigate any impacts and safeguard fishing activities and conservation efforts.

Seaweed farming as an eco-friendly alternative for Tanzanian fishing communities
Climate change, overfishing and habitat loss have caused a sharp decline in fish stocks around Pemba Island, off the coast of Tanzania. To find a new income from the sea, women from Pemba are turning to sustainable seaweed farming, Mongabay’s video team reported in May. Seaweed farming was introduced to the island in 1989. It […]
Glass eel smuggling booms despite bans, leaving species on the brink
- The illegal trafficking of critically endangered European glass eels continues to thrive, generating up to 3 billion euros ($3.5 billion) in peak years, with more than 1 million live eels seized in 2023 alone — mostly en route to East Asian aquaculture farms where they’re raised to maturity to produce the delicacy unagi.
- Europol describes the trade as a highly organized transnational crime involving smuggling, document fraud and money laundering, with sophisticated players using scientific expertise to keep smuggled eels alive during transit.
- Conservationists warn that removing juvenile eels from the wild disrupts their life cycle and ecosystem functions, worsening the species’ 90% population decline since the 1970s and threatening biodiversity in connected marine and freshwater systems.
- Experts call for stronger enforcement, improved monitoring, public awareness and habitat restoration to combat the trade and avert further ecological damage.

Red tape fouls a coastal community’s fight to protect fjords in Chilean Patagonia
- Fishing pens are considered sustainable fishing method and have been used in Chile’s Patagonian region since pre-Columbian times.
- Residents of the Huequi Peninsula have restored a fishing pen and discovered that it no longer catches the hundreds of fish it once did.
- They’re seeking to protect the Comau and Reñihué fjords, which are threatened by the fishing and aquaculture activity.
- They’ve applied for designation of the waters in the two fjords as a Marine Coastal Space for Indigenous Peoples, but the process, which is supposed to take three years at most, has now dragged on for five years.

Ghana to expand artisanal fishing zone amid trawler violations
Ghana has announced plans to expand the area in which small-scale fishers can operate, in response to persistent violations by industrial trawlers encroaching into this zone. The country’s inshore exclusion zone, or IEZ, will now extend 12 nautical miles (22 kilometers) from shore, up from 6 nmi (11 km) currently. Emelia Arthur, Ghana’s newly appointed […]
Tanzania’s Mafia Island eyes sea cucumber farming to prevent extinction
Residents of Mafia Island in Tanzania don’t really eat sea cucumber; they call it jongoo bahari, or “ocean millipede” in Swahili. But sea cucumbers are a prized delicacy in East Asia, where demand has fueled a black market for the spiny sea creatures, Mongabay’s Ashoka Mukpo reported in May. A kilogram of dried sea cucumbers […]
Specter of dams and diversion looms over Southeast Asia’s Salween River
- The Salween River, one of Asia’s last free-flowing rivers, supports Indigenous communities and biodiversity across China, Myanmar and Thailand, but faces threats from at least 20 proposed hydropower dams, mainly in Myanmar.
- Myanmar’s postcoup instability has stalled dam construction, though powerful armed groups and foreign investors, particularly from China and Thailand, remain key players in determining the river’s fate.
- The Thai-backed Hatgyi Dam and the Yuam River Diversion Project risk submerging villages, displacing Indigenous Karen communities, and diverting massive amounts of water for agriculture in central Thailand.
- Local resistance, legal challenges and transboundary activism are mounting, with critics calling for permanent protection of the Salween and condemning the exclusion of affected communities from decision-making.

Whales still aren’t ‘eating all the fish’ (commentary)
- Estimating the amounts of krill or fish consumed by whales has long been an obsession of the proponents of industrial whaling, who argue that these amounts are too large and then use the figures as justification to hunt whales.
- However, this research is pseudoscience, a new op-ed argues, and badly misunderstands — or willingly misrepresents — established principles of marine ecology.
- “In order to counter the wild imaginings of how marine ecosystems work put forth by whalers and their bureaucratic enablers in whaling nations, new thinking is required,” the former NOAA scientist writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Peru’s new bycatch training aims to help save hooked sea turtles: Q&A with fisher Gustavo Rosales
- Sea turtles often get caught on hooks intended for mahi-mahi in the waters off the coast of southern Peru.
- The government is training fishers in best practices for releasing turtles, seabirds and other species accidentally caught by fishing gear.
- A 2022 regulation for the mahi-mahi fishery requires that at least one crew member per boat has obtained a training certificate.
- “If it weren’t for the turtles, there would be no balance,” says Gustavo Rosales, a fisher from the city of Ilo, who says the training has been beneficial.

On its 50th anniversary, ‘Jaws’ continues to provoke shark conservationists
- This month marks the 50th anniversary of the release of Jaws, a Hollywood blockbuster that depicts a series of attacks by a massive great white shark — a “man-eater” — in a fictional New England beach town.
- Shark populations have plummeted since the film was released, and experts agree that Jaws misrepresented the nature of sharks and likely had a net negative impact, however small, on their population sizes and conservation status.
- Most of the experts reached for this article said the film had spurred interest in sharks, some of which was channeled in positive directions. In fact, some people who worked on the film later advocated for shark conservation.

Endangered angelshark decline may be overestimated, study shows
Previous reports of drastic declines in the elusive angelshark in Wales, U.K., may be overestimated and may be partly explained by changes in fishing trends throughout the past decades, according to a recent study. The angelshark (Squatina squatina), listed as critically endangered on the IUCN Red List in 2006, is a bottom-dwelling shark that can […]
French Polynesia creates world’s largest marine protected area
French Polynesia has announced the creation of the world’s largest marine protected area. Speaking on the first day of the United Nations Ocean Conference in France, French Polynesian President Moetai Brotherson said the MPA will cover the territory’s entire exclusive economic zone (EEZ), or 4.8 million square kilometers (roughly 1.9 million square miles). “We have […]
Death of tagged white shark on bather protection gear in South Africa sparks debate
The recent killing of a juvenile great white shark on a drum line — a shark control method consisting of baited hooks attached to floating drums — off the east coast of South Africa has sparked a debate over the measures employed to protect swimmers at the expense of the threatened species. The 2.2-meter (7.2-foot) […]
In Nepal, northernmost sighting of Eurasian otter raises hope, concerns
- The northernmost Eurasian otter sighting in Nepal was recorded in the Karnali River, raising hopes for the species’ range expansion. But as the animal was found dead in a fishing net, conservationists highlight challenges to the species’ conservation.
- Researchers emphasize the rarity of such sightings in high-altitude, remote areas like Humla, where otters had been considered cryptic or absent for decades.
- The discovery builds on a series of recent sightings across Nepal, including in urbanized Kathmandu Valley, suggesting a wider distribution than previously known.
- Threats to otters include overfishing, poaching, hydropower projects, sand mining and net entanglement, all of which imperil not just the Eurasian otter but also Nepal’s two other otter species.

Bumble Bee asks court to dismiss lawsuit alleging forced labor in tuna supply chain
- In March, four Indonesian men filed a landmark lawsuit in the U.S. against canned tuna giant Bumble Bee Foods, accusing the company of profiting from abuse and exploitation aboard Chinese-owned vessels supplying its tuna.
- The plaintiffs described brutal conditions while working on vessels that allegedly supplied albacore tuna directly to Bumble Bee, including physical violence, inadequate food, lack of medical care and withheld wages.
- Despite claims of traceability and sustainability, Bumble Bee and its parent company, Taiwan-based FCF, have been linked to a network of vessels implicated in labor abuses. Critics argue the company failed to act on repeated warnings from rights groups and resisted regulatory changes.
- On June 2, Bumble Bee filed papers requesting the federal court handling the case dismiss it on legal grounds. The next step will be for a judge to decide whether to dismiss it or let it proceed.

In a big win, Yurok Nation reclaims vital creek and watershed to restore major salmon run
- Four dams are now down on the Upper Klamath River in northern California in the largest river restoration project in U.S. history. But a rarely mentioned cold-water creek is essential to restoring health to what was once the third-largest salmon run on the West Coast of North America.
- Blue Creek is located just 25 km (16 mi) from the mouth of the Lower Klamath at the Pacific Ocean. Critically, it’s the first cold-water refuge for migrating salmon that enables the fish to cool down, survive, and move farther upriver to spawn. The dams and logging have damaged this important watershed for decades.
- The Yurok, California’s largest Indigenous tribe, lost ownership of Blue Creek to westward U.S. expansion in the late 1800s. In 2002, a timber company, negotiating with the Yurok, agreed to sell back the 19,000-hectare (47,100-acre) watershed to the tribe.
- It took Western Rivers Conservancy, an Oregon-based NGO, nearly two decades to raise the $60 million needed to buy the watershed. In a historic transition, Blue Creek returns this spring to the Yurok for conservation in its entirety. The tribe considers the watershed a sacred place.

Samoa’s new marine spatial plan protects 30% of the country’s ocean
- The Samoan government announced June 3 that it has enacted a law establishing a marine spatial plan to sustainably manage 100% of its ocean by 2030.
- The country has also created nine new marine protected areas that cover 30% of its ocean.
- Fishing is prohibited in the new protected areas, which include a migration route for humpback whales.
- The plan became law on May 1.

Mining company returns to haunt Thailand’s Karen communities as resistance mounts
- A long-dormant fluorite mine is being reopened in northern Thailand, but the ethnically Karen communities that live in Mae Hong Son province’s Mae La Noi district are staunchly resisting the return of the mining company.
- Universal Mining, a Thai company, aimed to reopen its fluorite mine in 2021 following an injection of Chinese investments, but so far has failed to secure the environmental impact assessment needed to recommence mining operations in Mae La Noi.
- Experts warn that Universal Mining may be able to find a way around the environmental regulations as the Thai government has earmarked parts of Mae La Noi for extraction in its national mining strategy.
- According to rights advocates, the conflict brewing between the mining company and the Karen communities is a reflection of limited rights Thailand gives its Indigenous People.

Tuna fishing devices drift through a third of oceans, harming corals, coasts: Study
- Drifting fish aggregating devices (dFADs) are floating rafts with underwater netting used by fishing vessels to attract tuna.
- A recent study estimated that between 2007 and 2021, 1.41 million dFADs drifted through 37% of the world’s oceans, stranding in 104 maritime jurisdictions and often polluting sensitive marine habitats.
- Strandings were most frequent in the Indian and Pacific oceans, with the Seychelles, Somalia and French Polynesia accounting for 43% of cases; ecosystem damage and cleanup costs fall on local communities.

Central Java villages take fast fashion to the cleaners at Indonesia’s Supreme Court
- Indonesia’s Supreme Court recently confirmed the bankruptcy of the country’s largest textile group, Sritex, which made garments for global fast fashion retailers like H&M.
- The court also awarded damages to 185 people in Central Java province who had filed a class action suit against a Sritex subsidiary over toxic gas leaks and river pollution.
- More than 10,000 Sritex workers lost their jobs as the heavily indebted firm collapsed, but local residents say the environment has showed signs of recovery since the subsidiary stopped producing synthetic fibers near Java’s longest river, the Bengawan Solo.

The blobby little sea squirt that stowed away across the Pacific to California
- In 2023, scientists found a nonnative species of marine invertebrate in a private marina near Los Angeles, California.
- The arrival of this new member of California’s marine fauna highlights the massive, largely uncontrolled movement of marine species via ships that travel the world.
- Concerned about potential ecological and economic impacts, the state of California has tried to curb the movement of nonnative marine species through regulations of large ships and commercial ports, but the regulations don’t apply to smaller vessels.
- Beginning in 2025, California will have to comply with less-stringent federal biofouling and ballast water regulations.

West Sulawesi erupts in protest over sand mining for Indonesia’s new capital
- Hundreds of protesters, including Indigenous and coastal youth from Karossa, Pasangkayu and Kalukku, rallied on May 5 at the West Sulawesi governor’s office to demand the closure of PT Alam Sumber Rezeki’s sand mining operations, citing environmental harm, permit irregularities and lack of community consent.
- Tensions flared after Governor Suhardi Duka dismissed anti-mining resistance as “thuggery,” triggering public outrage and a clash with security forces during the protest, where demonstrators were met with water cannons and no official response.
- The mining, tied to supplying materials for Indonesia’s new capital, Nusantara, has fueled a wider grassroots resistance across West Sulawesi, with activists condemning the criminalization of local opposition and calling for meaningful community involvement in environmental decision-making.

Delay in land reform fuels new wave of settlers and violence in the Amazon
- Grassroots organizations are settling new areas in the Brazilian Amazon amid disappointment that President Luiz Inácio Lula da Silva has been slow to jump-start the stalled land reform agenda.
- According to the federal land agency, Incra, about 145,000 people are inhabiting camps all over Brazil, waiting for a plot of land.
- In one of the Amazon’s deadliest regions, a group fighting for land was besieged by a dozen armed men hired by ranchers; even in established settlements, harassment by land grabbers and lack of government support drive settlers out of their plots.
- The stalling of the land reform agenda pushes Amazonian people further into the forest, driving the cycle of deforestation, or else to the outskirts of cities, where many struggle to make a living.

New study maps the fishmeal factories that supply the world’s fish farms
- In April, scientists published the first-ever open-source map of fishmeal and fish oil factories around the world.
- The scientists found 506 factories across some 60 countries, and in most cases were able to identify the companies that own them.
- Fishmeal and fish oil production is controversial because it can incentivize the overexploitation of ocean ecosystems, depleting marine food webs, and negatively impact coastal communities that rely on fish for nutrition and livelihoods.
- In addition to location data, the scientists collected data on the types of fish many of the factories use and whether the raw material they process is fish byproduct or whole fish, which critics view as more problematic.

Brazil’s offshore wind farms could sacrifice small-scale fishing in Ceará
- In Brazil, the expansion of coastal wind energy has already disrupted traditional communities’ way of life; now, the concern is that these impacts will be repeated at sea, after a bill regulating offshore wind energy was signed into law in January.
- In the state of Ceará, 26 projects overlap with small fishing zones used by hundreds of traditional communities, including maroon, Indigenous, fisher and extractivist groups that have had a direct relationship with the sea for generations.
- The northeast region seeks to expand offshore wind energy, as it is vital to the production of green hydrogen aimed for European markets.

How manatees won over an entire village
BARRA DO MAMANGUAPE — Brazil. It’s hard to imagine today, but manatees were once hunted and eaten. These gentle sea mammals were considered a delicacy in Brazil, with their meat consumed by local fishermen and their skin and oil exported to Europe during colonial times. This exploitation pushed the species to the brink of extinction. […]
Community-led system boosts fisheries in a corner of fast-depleting Lake Malawi
Lake Malawi’s fish stocks are declining, but one community stands apart: around Mbenje Island, a traditional fisheries management plan has ensured thriving fish populations for generations, Mongabay contributor Charles Mpaka reports. Landlocked Malawi is highly dependent on the lake, which supplies 90% of the country’s fish catch; more than 1.6 million people rely directly or […]
Angling for answers, this saltwater fishing group boosts research for better conservation
- Though anglers aren’t generally thought of as environmentalists, many people who fish are conservation minded, whether because it’s an outdoor pursuit, or because they wish to ensure future harvests.
- Whatever their reasons, there aren’t many groups that help anglers advocate for sustainable fishing regulations based on solid science, nor ones that also work to generate new data that helps them argue for better conservation.
- “Until we came along, there was no voice for those saltwater anglers who cared about conservation, but didn’t have enough time to put into it to really understand it,” says American Saltwater Guides Association vice president Tony Friedrich.
- His team not only helps its members articulate the need for conservation and regulation, they actively participate in developing data that helps managers set better limits, through projects like their GotOne App.

European body proposes mass killing of cormorants to protect fish stocks
A regional fishery body is seeking to reduce cormorant numbers across Europe through  “coordinated” culling, citing the aquatic birds’ reported impacts on fisheries and aquaculture. The European Inland Fisheries and Aquaculture Advisory Commission (EIFAAC), a body under the Food and Agriculture Organization (FAO) of the U.N., published its draft plan on April 25. The proposal […]
There’s something fishy about ‘blue economy’ proposals for sustainable marine management (commentary)
- Proposals for developing a “blue economy” emerged in the 2010s as a vision for sustainable ocean development, as communities across the world grappled with challenges of declining ocean health, economic crises and stalling development outcomes.
- Central to their appeal is a promise to transform human interactions with the ocean, promoting a shift toward ecological health, improved livelihoods and job creation, but too often these proposals have been driven by large nations and interests, rather than small coastal nations whose prosperity is most heavily linked with marine ecosystems.
- The author of this commentary warns that this sustainable ocean vision may be operating as a tool for pacifying demands for sustainable and equitable ocean relations, rather than as one that advances them.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Dredging and pollution threaten fishing in the Niger River
- Some fishers in Bamako, Mali’s capital, are raising concerns about dredging of the Niger River in search of gold.
- They say the combination of dredging and increasing plastic pollution is causing fish stocks to decline.
- Damage to the river’s ecosystems is taking a toll on their livelihoods, with some forced to give up fishing for the more lucrative, but environmentally destructive, activity of river sand mining.

Tuna talks bring wins for Indian Ocean sharks, but more needed, experts say
- At the most recent round of Indian Ocean tuna talks, countries adopted measures to curb shark finning, expand the scope of bans that prohibit fishers from holding on to sharks caught as bycatch and restrict the use of harmful fishing gear.
- Conservationists said the measures will reduce the unwanted capture, or bycatch, of sharks that get hauled in by fishers targeting tuna and tuna-like species.
- A complete retention ban is already in place for oceanic whitetip sharks and thresher sharks in the Indian Ocean, and it will most likely be extended to whale sharks.
- A partial ban on retaining shortfin mako, an overfished endangered species, will take effect in 2026. However, scientists fear the measures to save the Indian Ocean shortfin mako may not be enough.

Protecting coastal waters may be the best investment you’ve never heard of, says Kristin Rechberger
- In this interview, Kristin Rechberger—founder of Dynamic Planet and a Mongabay board member—discusses Revive Our Ocean, a new initiative empowering coastal communities to establish marine protected areas (MPAs) that benefit both nature and livelihoods.
- With only 3% of the ocean fully protected and the 2030 “30×30” target looming, Rechberger argues that waiting on governments isn’t enough; community-led efforts are crucial to scaling marine conservation rapidly and equitably.
- Drawing on a decade of experience creating large offshore marine reserves, Rechberger is now focusing on coastal regions where local communities have a direct stake in healthy seas—but often lack the legal authority, tools, or support to act.
- She emphasizes that marine protection is not only ecologically effective but economically smart, citing examples like Spain’s Medes Islands Reserve and Mexico’s booming dive tourism as models for prosperity through conservation.

Under Trump, US retreats from global fisheries and oceans leadership
- The United States has long been an international leader in fisheries and oceans science, with influence at international fora that it has sometimes wielded to support conservation measures and crackdowns on illegal fishing.
- However, U.S. influence at fisheries and oceans fora appear to be waning during the second Trump administration, which could compromise fisheries health and marine conservation, experts say.
- The administration, which took office Jan. 20, has begun to institute a program of budget and staff cuts at U.S. departments and agencies that work on fisheries and oceans governance, while turning away from or undercutting multilateral organizations.

Southeast Asia’s fisheries thrive despite decades of overfishing warnings: Study
- Overfishing in Southeast Asia’s coastal waters is a long-standing concern, but recent research suggests a more optimistic outlook, with 43% of marine stocks classified as underfished — 3.6 times higher than the global average.
- The study, covering stocks across the Indian and Pacific Oceans, highlights the region’s relatively abundant fisheries, particularly among pelagic species, 63% of which are underfished.
- Southeast Asia’s fisheries production surged by 7.1 million metric tons from 1993 to 2022, the largest increase globally, with Indonesia, Vietnam and Myanmar as major contributors.
- The research underscores the importance of small-scale artisanal fisheries that use nonselective methods to target multiple species, and co-management frameworks to maintain production and sustainability.

Oil companies have downplayed extent of spills in Gulf of Mexico, investigation finds
- Mongabay Latam and Data Crítica examined and compared official data of oil spills in the Gulf of Mexico, including satellite images by scientists studying oil spills and evidence compiled by fishing communities. Their analysis found that most oil spills are not reported.
- Occasionally, even the spills that are reported are played down. The volume of the Ek’ Balam oil spill in 2023 — the most serious spill in Mexico in recent years — was under-reported by 10 to 200 times, according to calculations performed by scientists using satellite images of the disaster.
- Between January 2018 and July 2024, the government of Mexico initiated 48 sanctioning processes against oil companies, but fines were only imposed in fewer than half of those cases. And only eight of those fines have been paid.
- Fishers are demanding oil companies release actual data and take responsibility and the government take action to protect their environment and livelihood.

Fishing cats misunderstood, misidentified in Nepal’s Kapilvastu
- Fishing cats in Nepal are often misunderstood and mistaken for leopards or blamed for fish losses, leading to retaliation and conflict with fish farmers.
- Surveillance measures like CCTV and myths have fueled fear and misinformation, despite little evidence showing fishing cats as major threats to aquaculture.
- A conservation initiative called “fish banks” tried to reduce conflict by compensating farmers with fish instead of money but had mixed results and eventually lost funding.
- Experts emphasize the need for science-based conservation, better population data and public education to protect fishing cats and promote coexistence in human-altered landscapes.

Indian trawlers leave Sri Lankan small-scale fishers a ravaged, bereft sea
- Bottom trawlers from India’s southern state of Tamil Nadu have been encroaching Sri Lanka’s northern waters for years, carrying out destructive fishing practices that have caused serious depletion of fish stocks and damaged marine habitats.
- Meanwhile, Sri Lanka’s local small-scale fishers continue to struggle due to reduced catches, destruction of their fishing nets and financial loss while being forced to fish in limited nearshore areas or abandon fishing temporarily to avoid conflict with the trawlers.
- In this political bone of contention, Tamil Nadu has been demanding reclamation of Katchatheevu — an uninhabited island between India and Sri Lanka — to gain unrestricted fishing rights, and the past bilateral promises to phase out bottom trawling have gone unfulfilled.
- Sri Lanka banned bottom trawling in 2017 and now needs to take specific actions to prevent illegal bottom trawling in its northern waters to avoid the risk of fisheries there from collapsing.

Sweeping cuts and deregulation imperil U.S. fisheries, experts warn
- The United States has long had one of the best systems of fisheries management in the world, supporting 2.3 million jobs and a relatively high number of healthy fish populations.
- The Trump administration is enacting sharp cuts to the budget, staff and facilities of the agency that manages U.S. fisheries, the National Oceanic and Atmospheric Administration (NOAA), and on April 17 ordered widespread deregulation of fisheries.
- The administration says the changes are necessary to reduce government waste and fraud, save taxpayer money, create jobs and enhance profitability, but experts and former NOAA employees told Mongabay these moves have been poorly planned and will be “devastating” for U.S. fisheries.
- The staff cuts, regulatory changes and facilities downsizing are not easy for the public to track, raising questions about the transparency of the Trump administration’s moves.

15 years after the BP oil spill disaster, how is the Gulf of Mexico faring?
- The Deepwater Horizon disaster on April 20, 2010, was the largest offshore oil spill in U.S. history, releasing an estimated 4.9 million barrels of oil into the Gulf of Mexico over nearly three months.
- Fifteen years later, the gulf ecosystem shows a complicated picture of both resilience and lingering damage, with some species, like brown pelicans, recovering, while others, like humans, dolphins and deep-sea corals, continue to struggle with long-term health impacts.
- The disaster prompted an unprecedented legal settlement directing billions toward restoration projects, though experts debate whether these funds have been used effectively for ecosystem-scale recovery.
- Climate change remains the “800-pound gorilla in the room,” threatening the gulf’s future resilience, one expert said, with others warning that continued pressure from fossil fuel development, agricultural runoff and other threats could push the system beyond its capacity to recover.

Mangroves mount a fragile green revival in Iraq’s toxic south
- Sea-level rise and upstream damming have worsened saltwater intrusion in the Shatt al-Arab River, pushing brine deep into Iraq’s interior and threatening agriculture, fishing and marshland ecosystems.
- A mangrove-planting project has been launched as a nature-based solution to combat coastal erosion, saltwater intrusion and pollution — threats that not only endanger Basra’s coastline but also the freshwater marshlands farther inland.
- Despite scientific backing and community support, the project faces significant obstacles like untreated sewage and industrial waste, while limited government support further hampers the project’s long-term viability and impact.

Vital Mekong fish corridors tracked for first time, but funding cuts threaten future research
- By implanting fish with small electronic transmitters, researchers were able to track key migration corridors in the Mekong River.
- The findings underscore the threat that dozens of planned dams along the Mekong will cut off these vital migratory paths.
- The study, which the lead author describes as a “pilot effort,” was funded by USAID; the funding gap caused by the U.S. foreign aid freeze leaves the future of such research in question.

Trump opens massive marine protected area to commercial fishing
U.S. President Donald Trump has signed a proclamation allowing commercial fishing in Pacific Islands Heritage Marine National Monument (PIH), a massive marine protected area home to threatened fish, sea turtles and marine mammals. The proclamation says U.S.-flagged vessels may now fish within 50-200 nautical miles (90-370 kilometers) inside PIH’s boundaries. While the proclamation and factsheet […]
How Mexican fishers are protecting an endemic oyster — and its ecosystem
- In Mexico’s Nayarit marshes on the Pacific Coast, the work of a fishing group called Ostricamichin has enabled the recovery of the Cortez oyster, an endemic and economically important mollusk, along with other marine species.
- The Marismas Nacionales Nayarit National Reserve, where the Cortez oyster is cultivated, accounts for 45% of Mexico’s national fishing production, thanks to floating rafts that help grow the endemic species in its waters.
- However, members of Ostricamichin say their project is threatened by climate change and illegal fishing. But the biggest threat, currently, is a proposed dam project which, they say, would devastate the delicate ecosystem.

In an ancient Javanese sultanate, coastal women battle climate fallout
- The coast of Demak district, the site of the first Islamic sultanate on the island of Java, has been inundated by the sea over decades owing to groundwater extraction and development.
- The erosion of human settlements is likely introducing new risks for women: “Our conclusion is that women and children, as well as poor families, including the elderly and disabled, are the most vulnerable,” a local legal aid nonprofit told Mongabay.
- Globally, around 90% of fish species are either fully exploited or overfished, and climate change is set to worsen the crisis by disrupting fish reproduction as oceans warm and acidify.

Fishing rights, and wrongs, cast small-scale South African fishers adrift
- A community of mixed-race families has lived and fished in South Africa’s Langebaan Lagoon since the 1800s.
- Starting with the former apartheid government in the 1970s, a series of conservation-oriented decisions ostensibly aimed at protecting fish stocks have slowly squeezed the number of these fishers allowed to operate in the lagoon.
- The government now says fish stocks have collapsed and it has reduced the number of small-scale fishers operating in the lagoon even further, while allowing recreational fishing to continue unimpeded. For their part, the fishers deny the stocks have collapsed, and blame declining catches on industrial developments.
- One expert likened the three-decade-long exclusion of the Langebaan net fishers to a case of fortress conservation, in which local people are squeezed out of nature and denied access to resources they’ve long used in order to preserve them for elites.

Seychelles becomes first country to comply with fisheries transparency standard
- Seychelles, an archipelagic nation off the eastern coast of Africa, has become the first country to comply with the Fisheries Transparency Initiative (FiTI) standard that lays down what information about a country’s fisheries sector should be published online by public authorities.
- When it committed in 2016 to becoming FiTI-compliant, Seychelles signed up to provide complete and up-to-date information on its fisheries sector that would be useful not just to policymakers but also to civil society organizations and the public.
- Seychelles’ FiTI-compliant status signals marked improvements in data availability, but it doesn’t guarantee that all the information on the fisheries sector is complete and fully accessible, with experts pointing out that some critical gaps remain.
- For example, fishing access agreements struck between the Seychelles and other governments, industry associations and private companies are now available online, but critics say decision-makers remain unable to evaluate them fully.

As Acapulco’s mangroves disappear, Mexico takes strides to protect its coastal forests
- One of Acapulco’s lagoons has experienced the near-complete loss of its mangroves due to urbanization and hurricanes.
- Another Acapulco lagoon has also lost portions of its mangroves, affecting the local fishing industry.
- Overall, the Mexican state of Guerrero has lost more than half of its mangroves since 1979.
- Mexico’s government is working with international organizations, scientists and local communities to restore the country’s lost mangroves.

Peruvian fishers sue for additional compensation after big December oil spill
- On Dec. 22, 2024, a pipeline leak at the New Talara Refinery in northern Peru spilled oil into the Pacific Ocean, coating 10 kilometers (6 miles) of coastline in black.
- Three days later, the Peruvian environment ministry declared a 90-day environmental emergency, paralyzing tourism and work for more than 4,000 artisanal fishers.
- Now, more than three months later, the fishers have returned to work on a sea dominated by the oil industry. They say the compensation they received from the refinery owner, state-owned oil company Petroperú, is insufficient and they are seeking more.
- For its part, the company says it has met its commitments.

Smuggling networks exploit migrant debt to fuel tiger poaching in Malaysia, study shows
- Fewer than 150 critically endangered Malayan tigers (Panthera tigris jacksoni) remain in the wild, and poaching for the illegal wildlife trade poses a major threat to their survival.
- A new study links human trafficking to Malayan tiger poaching, tracing how indebted Vietnamese migrant workers in Malaysia enter the illegal wildlife trade, and how network managers and fishing boat captains smuggle tiger parts to Vietnam by boat.
- Unlike a single kingpin-controlled network, Malayan tiger trafficking is driven by interconnected, nonhierarchical and small Malaysia-based groups that adaptively cooperate to maintain a seamless supply chain, according to the study.
- To slow the illegal Malayan tiger trade, the authors call for increasing penalties for traffickers, deterring poachers through clear messaging, and prioritizing key coastal communities in both countries for interventions aimed at disrupting transboundary crime and diverting economically vulnerable people from joining the trade.

In Pakistan, sea level rise & displacement follow fisherfolk wherever they go
- Rising sea levels are displacing fisherfolk in Pakistan’s coastal areas, forcing them to move to higher ground, such as Karachi, where they now face saltwater intrusion and other climate impacts.
- For many, this displacement is not just about losing homes, but also cultural heritage, traditions and livelihoods, with women, in particular, losing economic freedom as fishing communities decline.
- The Pakistani government lacks a formal policy for the voluntary migration of climate refugees, and while efforts like mangrove restoration have been attempted, they have not significantly alleviated the fishing community’s problems.
- Karachi is projected to receive 2.3 million climate migrants by 2050, primarily due to rising sea levels, saltwater intrusion, and other climate-related catastrophes.

Panama conducts large illegal fishing bust in protected Pacific waters
- Panamanian authorities seized six longliner vessels on Jan. 20 for fishing illegally in protected waters. They also opened an investigation into an additional 10 vessels that surveillance data showed had apparently been fishing in the area but left by the time authorities arrived.
- The seizures took place in the Cordillera de Coiba, a marine protected area that’s part of the Eastern Tropical Pacific Marine Corridor, which connects several MPAs in four countries. It was the largest illegal fishing bust in the history of Panama’s MPAs.
- The vessels, whose activity is still under investigation, were Panamanian-flagged, meaning they were registered in the country, but the identity and nationality of the owners isn’t clear.
- The surveillance work in the case was done in part through Skylight, an AI-powered fisheries intelligence platform, and was supported by a group of fisheries monitoring nonprofits.

Pirates of the Pacific terrorize artisanal fishers on the Peruvian coast
- For more than 15 years, artisanal fishers in the Tumbes region of northwestern Peru have been plagued by an evil that seems straight out of an adventure book: pirate attacks.
- But this is no fiction: more than 20 fishers have been killed in the past 21 years during pirate attacks.
- To date, no one has been tried or even arrested for these crimes.
- Although the police dismantled a pirate gang in 2018, the situation hasn’t improved significantly, and fishers are forced to pay protection fees to the pirates.

How Peruvian cockfighters could tip the scales for endangered sawfish
- In Peru, where cockfighting is not only legal but regarded as an important cultural practice, cockfighters have long brought their roosters to fight wearing sharp spurs fashioned from the “teeth” of sawfish.
- The largetooth sawfish (Pristis pristis), the only sawfish that lives in Peru, is incredibly rare and considered critically endangered.
- Advocates for the species both within and outside the sport have increasingly realized that cockfighting plays a role in preventing or hastening its demise in Peru and are working to eliminate sawfish spurs from the sport.
- Although trade in sawfish parts is now illegal in Peru, times are tough for the country’s artisanal fishers. Experts worry that demand for sawfish spurs could drive more sawfish killings than the species can support.

Tanzania’s marine reserves offer long-term benefits to communities, study finds
- The Tanzanian government established five marine protected areas (MPAs) in the 1990s to safeguard falling fish populations.
- Over nearly 20 years, villages near these protected areas became less dependent on fishing and agriculture and saw their standard of living rise faster than communities farther away, a new study shows.
- The authors didn’t find evidence that MPAs impacted fishing success in nearby settlements.
- They hypothesized that the MPAs lifted local economies by attracting tourists.

5 takeaways from the 2022 Repsol oil spill in Peru
- On Jan. 15, 2022, the largest oil spill in Peruvian history occurred when a pipeline broke during the offloading of oil from a tanker to a refinery owned by the Spanish company Repsol.
- 11,000 barrels of crude oil spilled into the ocean off the coast of Callao, near Lima. It sullied miles of beaches, killed untold marine animals and upended the livelihoods of thousands of fishers.
- Three years later, the consequences of the tragedy persist, even as the oil industry’s activities along the coast of Peru continue to cause environmental disasters.
- These are the latest details of the case, which has continued to affect Peru’s marine ecosystem and the fishers who depend on it to survive.

Plastic pollution cuts into fishers’ livelihoods in Ecuador and Peru
- A new study in Peru and Ecuador has found that artisanal fishers are losing revenue due to prolific plastic pollution in the ocean.
- Researchers surveyed 1,349 artisanal fishers in Ecuador and Peru and found that the more waste generated locally, the greater the financial losses.
- This is reflected in the national economy, with losses in Ecuador and Peru’s domestic product from fisheries.
- The study is part of the Pacific Plastic: Science to Solutions initiative, which is represented on an intergovernmental committee currently negotiating a treaty on plastic pollution.

Sumatran culinary heritage at risk as environment changes around Silk Road river
- Research shows that landscape changes across the Musi River Basin in Indonesia’s South Sumatra province risks food security across the river delta as fish stocks diminish and protein availability declines, including in the provincial capital, Palembang.
- Some fish traders and artisans in the city of 1.8 million worry culinary culture in Palembang is becoming endangered as rising sedimentation in the Musi River threatens the freshwater snakehead murrel fish.
- Reporting in March, during the fasting month of Ramadan, showed prices of food staples made from this fish increasing sharply from previous months as demand surged for fast-breaking events.

Fish-tracking robot aims to make fishing more sustainable in developing nations
- Israeli scientists have developed a solar-powered underwater robot called SOUND that can roam autonomously for five days at a stretch, counting fish and communicating its findings back to observers onshore.
- The goal is to help local fishers in developing countries understand their fish populations so they can avoid overfishing and the capture of unwanted species.
- They tested the system in Malawi, among other locations, where fishers are facing a myriad of problems related to uncontrolled fishing.

Rep from American Samoa calls for opening protected Pacific waters to tuna fishing
- U.S. Congresswoman Amata Radewagen, who represents American Samoa, has urged the Trump administration to reopen most of Pacific Islands Heritage (PIH) Marine National Monument, a vast protected area in the Central Pacific Ocean, to industrial tuna fishing.
- Radewagen’s request came in a letter to President Donald Trump dated Jan. 23. It was accompanied by a background document that called for an executive order opening all Pacific marine national monuments and national marine sanctuaries to tuna fishing.
- Conservationists sharply criticized Radewagen’s move, while a tuna trade group supported it.
- Some details of the letter and background document, which Radewagen’s office shared with Mongabay, have not previously been publicly reported.

USAID funding cuts jeopardize creation of Ghana’s first Marine Protected Area
- The U.S. foreign aid freeze blocks the establishment of Ghana’s first Marine Protected Area (MPA).
- The MPA was being created under the Ghana Fisheries Recovery Activity (GFRA), a USAID-funded program that aimed to restore pelagic fish stocks crucial for the country’s food security.
- Ghana’s small pelagics, consisting mostly of sardines, anchovy and mackerels, make up about 60% of local fish landings and serve as a primary source of protein for almost two-thirds of the country’s population.
- The West African nation depended heavily on U.S. foreign aid to preserve its small pelagic fisheries sector, and without other funding, there could be cascading impacts on its economy.

Caribbean reef sharks rebound in Belize with shark fishers’ help
- Endangered Caribbean reef sharks (Carcharhinus perezi) and other shark species are making a striking recovery in Belize after plummeting due to overfishing between 2009 and 2019, according to recent observations.
- Experts say the establishment of no-shark-fishing zones around Belize’s three atolls in 2021 is what enabled the population boom.
- A remarkable cooperation and synergy among shark fishers, marine scientists and management authorities gave rise to the shark safe havens and led to their success, experts say.

To save a Honduran reef, locals craft custom gear and hunt invasive lionfish
Without a natural predator, invasive lionfish, which damage coral reefs, have become widespread throughout the Caribbean over the last several decades. To prevent further harm off the northern coast of Honduras, locals have resorted to crafting their own spears to effectively and safely hunt lionfish, reports Mongabay contributor Fritz Pinnow. Julio San Martín Chicas, program […]
Liberia to start industrial shrimp fishing, worrying artisanal fishers
- Liberia plans to expand industrial bottom trawling in the country by authorizing a new fishery for high-value shrimp.
- However, the government has released few details about the plan, including how much shrimp it will allow the new fishery to exploit, when the trawling would begin, or how it would be regulated.
- The country’s umbrella organization for artisanal fishers casts the move as a threat to the livelihoods, safety and food security of Liberia’s more than 57,000 artisanal fishers, as well as to the country’s marine life.

Study finds signs of tuna abundance outside marine protected areas
- Experts debate the degree to which marine protected areas (MPAs) that are closed to industrial fishing boost fish population abundance or fishing success outside their borders.
- A recent study indicates that large-scale no-fishing MPAs do provide “spillover” benefits: It showed purse seiner vessels caught more tuna per unit of fishing effort in the 100 nautical miles (185 kilometers) surrounding large MPAs than they would have if the MPAs did not exist.
- Such findings could strengthen the case for establishing large MPAs, which could be on the table once international agreements, including the High Seas Treaty, are rolled out in coming years.
- Some fisheries scientists argue that MPAs are not a good method of fisheries management; one critiqued the recent study.

Illegal sea fence displaces fishers and sparks land scandal near Jakarta
- A property developer installed 30 kilometers (19 miles) of bamboo fencing in the sea near Jakarta, blocking fishers’ access; an investigation revealed it encompassed 280 ocean plots for which title deeds had been illegally issued.
- The fence has forced many fishers to stop working, while coastal farmers have lost their land to the same luxury development; residents also face eviction with no clear alternatives.
- Authorities have sanctioned a handful of individuals from the public and private sectors and started revoking the illegal deeds, but activists are demanding criminal prosecutions against the companies responsible.
- The case highlights weak oversight of Indonesia’s national strategic projects, raising concerns over environmental destruction, loss of livelihoods, and government favoritism toward big developers.

Lake Chad isn’t shrinking — but climate change is causing other problems
- Contrary to popular conception, Lake Chad is not shrinking; new research shows that the volume of water in the lake has increased since its low point in the 1980s.
- However, more intense rain in the region, coupled with the impacts of historic drought, increases the risk of flooding.
- The region is also plagued by continuing conflict and insecurity, making to harder for people to adapt to the impacts of climate change.
- A Lutheran World Federation project is working with communities in the Lake Chad Basin on sustainable agriculture and fisheries, land restoration, conflict resolution and more.

India’s fisherwomen getting left behind by blue economy policies
Women make up nearly half of India’s marine fisheries workforce, yet policies to strengthen the country’s blue economy are leaving women behind, reports contributor Priyamvada Kowshik for Mongabay India. India’s draft blue economy policy framework aims to significantly boost the contribution of marine resources to the country’s GDP, and at the same time improve the […]
Thailand’s last sea nomads confront a changing world
MU KOH SURIN, Thailand — Ngui slips beneath the waves, his movements effortless and precise. He’s done this thousands of times, diving deep to find fish and crustaceans hiding beneath the coral shelves of the Andaman Sea. His catch today is different. A sheet of black plastic, snagged on a rock 50 kilometers (30 miles) […]
Endemic fish wiped out in Brazilian Amazon hydroelectric dam area, study finds
- The construction of the Balbina hydroelectric dam in the Brazilian Amazon led to the loss of seven endemic fish species in the Uatumã River, researchers have found.
- The hydroelectric dam has transformed the Uatumã River’s fast-flowing habitats into static environments, making them unsuitable for certain fish species.
- Researchers call for the investigation of unaffected tributaries, such as the Jatapu River, as possible refuges for the missing species and future conservation efforts.
- The study underscores the broader threat of hydropower dams and other environmental stressors, like industrial fishing and climate change, to Amazonian fish populations.

Conservationists suspect fishing nets, increased tourism for sea turtle deaths in Bangladesh
- More than 100 olive ridley turtles were found dead in Bangladesh’s Cox’s Bazar Beach in the last few weeks.
- Conservationists blame the uncontrolled use of fishing nets and increased tourism during the turtle nesting period to have played a key role in the incident.
- The olive ridley’s main nesting grounds are the various islands in the southeastern district, Cox’s Bazar in the Bay of Bengal, and they come to the beaches to lay eggs before returning to the sea.
- Over the last three years, Bangladesh saw there was an increased number of olive ridley turtles and hatchlings thanks to different conservation programs.

Illegal seabed dredging surges as Indonesia resumes sand exports
- Reports of unauthorized seabed dredging have surged following Indonesia’s decision to resume sea sand exports in 2023, raising environmental concerns and exposing weak marine law enforcement.
- Officials argue that removing sediment helps ocean health and prevents land buildup, but experts and activists warn the policy contradicts marine conservation efforts and lacks transparency.
- Dredging threatens mangroves, coral reefs, and fish populations, with projected losses to fishing communities far outweighing state revenue and corporate profits.
- Experts urge the government to reinstate the export ban, conduct thorough environmental impact assessments, and allocate funds for ecological restoration and affected communities.

Small-scale fishers’ role in feeding the planet goes overlooked: Study
- A new study found that small-scale fishing accounts for at least 40% of catch worldwide and provides employment for 60 million people, more than a third of whom are women.
- Small-scale fishing could provide a significant proportion of the micronutrient intake for the 2.3 billion people on Earth who live near coastlines or inland bodies of water, the study found.
- More than 60% of small-scale fishing catch in the studied countries came from places where small-scale fishers had no formal rights to participate in management and decision-making processes.
- “We wanted to have a paper that provided key findings at the global level for each of these dimensions, so that it will be clear for governments that small-scale fishing cannot continue to be overlooked in terms of policymaking,” one of the study authors told Mongabay.

Unchecked illegal trawling pushes Indonesia’s small-scale fishers to the brink
- Small-scale fishers in Indonesia face declining catches as illegal trawlers deplete fish stocks in near-shore waters, violating exclusion zone regulations.
- Trawling, a destructive fishing method banned in certain areas, is widely practiced due to weak law enforcement, with local authorities citing budget constraints for lack of patrols.
- The impact on traditional fishers has been severe, with daily catches and incomes plummeting, leading to economic hardship, job changes and social issues, such as increased poverty and divorce rates.
- Fishers and advocacy groups are calling for stricter enforcement of fishing laws and government action to protect small-scale fishers’ rights and livelihoods.

Researchers find microplastics for the first time in the Finnish Sámi waters
- Scientists and Indigenous Skolt Sámi knowledge holders have detected microplastics in the lakes and rivers that the Indigenous Sámi communities have used for generations.
- The concentration of microplastics was small, researchers found, but it was still higher than the quantity expected, given that the area is thought to be pristine.
- The average size of the microplastics was 100 micrometers and concentrations ranged from 45 to 423 microplastic particles per cubic meter.
- While the source of the microplastics is unknown, researchers say one of the sources could be from the transboundary pollution accumulated in fish that come from the ocean to the freshwaters for spawning.

Mexican fishers relocate in wake of sea level rise, raising job concerns
- In the southern Mexican state of Tabasco, most residents of the El Bosque community have been relocated after their homes were destroyed by coastal erosion.
- Community members have expressed concern about job security, as the new site is 12 kilometers (7.4 miles) away from the sea and residents cannot as easily fish, which they depend on for their livelihoods.
- While planned relocation has emerged as a critical strategy to protect those impacted by climate change, reports have shown relocation does not always reduce socioeconomic pressures.
- Although fishers from El Bosque are concerned about the impact of the relocation on their livelihoods, some see it as an opportunity for younger generations to seek alternative livelihoods and better opportunities.

Over 1,100 dead olive ridley turtles wash ashore in southern India
More than 1,100 dead olive ridley turtles have washed ashore on the beaches of Tamil Nadu state in southern India this month. Most were found near the state capital, Chennai. “I never heard [of] such large numbers of turtles stranded at any beaches of Tamil Nadu at least in the last three decades,” K. Sivakumar, […]
Underwater citizen science reveals the specter of ghost fishing in Thailand
- Teams of scientists and hobbyist scuba divers have assessed the extent of discarded fishing gear on Thailand’s marine wildlife, finding it poses a pervasive threat to a huge range of species.
- Discarded or “ghost” fishing gear comprises 10% of all marine plastic debris in the ocean, persisting for decades and passively catching and killing species from sea snails to whale sharks.
- Thailand is famed for its recreational diving, and efforts are underway to retrieve ghost gear from the ocean and rescue animals found entangled, as well as to work with fishers to help them recycle their old equipment.
- Experts say preventing gear from entering the ocean in the first place is paramount; solutions must extend beyond cleanup and recycling efforts to encompass policy reform, economic incentives, and improved infrastructure.

Fishing boats spotted competing with whales in Antarctica for krill
Nearly all of Antarctica’s iconic wildlife, from penguins to seals and whales, depend on krill, tiny crustaceans that make up the base of the food chain. Krill are also sought after by humans, who scoop them up using massive fishing boats, potentially putting whales in danger, scientists warn. The fishing boats and whales are “going […]
Ogoni women restore mangroves and livelihoods in oil-rich Niger Delta
- After decades of crude oil spills and the introduction of invasive plant species, thousands of hectares of mangroves in the Niger Delta are destroyed, impacting aquatic species and women’s livelihoods.
- Ogoni women from coastal villages, supported by the Lokiaka Community Development Centre, have been at the forefront of reforestation efforts.
- The women have planted 2.6 million mangrove trees since 2018, drawing attention from a government agency that hired them to share their knowledge and plant mangroves for its oil spill rehabilitation project.
- Around 300 women from Ogoni communities have been trained in mangrove reforestation.

Thai farmers demand action to restore ecosystems, compensate for invasive fish
- Citizens rallied in Bangkok this week demanding accountability and action from the government and private corporations following an outbreak of invasive fish that has ravaged Thailand’s freshwater ecosystems and aquaculture industry.
- Blackchin tilapia, an omnivorous species native to West Africa, is highly adaptable, breeds rapidly and is capable of outcompeting native wildlife and commercially farmed species, including shrimp.
- Thailand’s largest agricultural conglomerate has come under scrutiny because it obtained a permit to import the species in 2010, shortly before the first detections in the wild in the same province as its research facility.
- The activists urged the government to eradicate the species, compensate affected farmers and identity the parties responsible for the outbreak.

We need a North Pole Marine Reserve to secure a healthy future for Arctic waters (commentary)
- In 2024, the cod fishing moratorium on Newfoundland’s Grand Banks was lifted, 32 years after a historically significant ecological collapse of the fish’s population was caused by overfishing.
- The Central Arctic Ocean Fisheries Agreement signed in 2019 provides an example of how to address the threat from such overfishing by using the precautionary principle, international collaboration and science led evaluations of fish stocks.
- The future health of Arctic marine ecosystems can be secured by establishing a North Pole Marine Reserve, a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

South Australia bans fishing of many sharks and rays in its waters
The state of South Australia has banned fishing of several endangered or critically endangered sharks and rays in its waters. In a media release dated Dec. 11, the state government said the new rules prohibit both recreational and commercial fishing of critically endangered species such as the whitefin swellshark (Cephaloscyllium albipinnum), oceanic whitetip shark (Carcharhinus […]
After trial and error, Mexican fishers find key to reforesting a mangrove haven
- David Borbón and his community are working to restore mangroves in a fishing village within Mexico’s El Vizcaíno Biosphere Reserve, one of the country’s largest protected areas.
- The mangroves act as a natural barrier, protecting the coastal community and ecosystems from hurricanes and other severe weather.
- Borbón, who wasn’t formally educated in any science, conducted a series of experiments to find the best method to reforest the area’s declining mangrove forests and settled on a direct sowing technique that replicates natural patterns.
- With the support of his family and community, he has now planted more than 1.8 million mangroves and largely facilitate the recovery of the mangrove ecosystem.

Brazil’s shipping channel plans in Amazonian rivers will worsen climate change, experts warn
- Dredging and rock-blasting ever-drier rivers for new channels in Brazil might not achieve agribusiness’s goal of cheaper, year-round transport, experts warned, suggesting existing railways as price-comparable and more climate-resilient.
- Though waterway transport is promoted as lowering emissions, in fact proposed new shipping channels on the Tocantins and Madeira rivers increase carbon emissions and deforestation, experts told Mongabay.
- New shipping channel plans used old water data, stopping in 2017 for the Tocantins channel, and didn’t do climate risk projections or climate impact studies. Experts urge these studies must be done, or risk tens of billions of investments in rock-blasting and dredging river beds, leaving “ruins” and “abandoned projects.”
- An August lawsuit by federal prosecutors charges that licensing of rock-blasting and dredging in a 500-km stretch of the Tocantins River in Brazil is an illegal “trick” to circumvent legally required full environmental review of the whole Araguaia-Tocantins channel, for which an economic-technical feasibility study was never done. In March 2022, Ibama’s licensing director determined it was “unviable.”

‘These stories deserve to be told’: Shining a light on secretive fisheries managers
In 2024, the U.N.’s climate and biodiversity conferences, COP29 and COP16, drew the attention of more than 3,500 media delegates and 1,000 journalists, respectively. Though these massive global negotiations are consequential for international policy on the environment and have human rights implications, there were also international negotiations this year on managing the majority of the […]
Climate change forces Jakarta fishing families to marry off young daughters
Climate change is driving families on Indonesia’s northern Javanese coast toward child marriage as a survival strategy amid dwindling fish stocks and increasing economic hardships, two Mongabay reports show. Mongabay contributor Maulia Inka Vira Fendilla traveled to North Jakarta’s Kalibaru neighborhood in 2023 and met Janah and Jaroh, sisters who were both married off at […]
Balochistan’s Gwadar city sits at the crossroads of climate and conflict
- A new study examines the links between conflict and climate in Pakistan’s Balochistan province, where extreme weather can be a threat multiplier.
- The port city of Gwadar serves as an example, as local residents have long had grievances against the state, which were exacerbated by recent flooding that killed several people and displaced hundreds.
- Experts highlight the absence of data-driven policies, citing a gap in research that has hindered solutions; they call for investment in data and the inclusion of local people in decision-making and infrastructure planning.

‘Shifting baselines’ in Cabo Verde after 50 years of declining fish stocks
- In Cabo Verde, as in many low-income countries in Africa, the historical record of fish catch is incomplete, making it hard to know what’s been lost and what’s required to fully rebuild.
- In a new study, researchers interviewed fish workers to understand how catches have changed over the last five decades, finding evidence of a major decline in volume of catch and maximum size of key species.
- The study also shows that young fishers and fishmongers don’t fully realize the scale of the loss — a case of what scientists call “shifting baselines.”
- Fishing communities on the West African mainland tell a similar story of decline, pointing to the urgency of centering local knowledge when devising fisheries management and conservation policies.
