Why are they killing this beautiful fish?
Lionfish are beautiful, venomous and devastating Caribbean reefs. In Honduras, divers are fighting back with homemade spears, hunting competitions and by putting lionfish on restaurant menus. Watch the full film to meet the community fighting back against one of the Caribbean’s most destructive invasive species.
Marine conservation collides with mining in Indonesia’s biodiversity-rich Moramo Bay
- Pressure on a protected marine area in Indonesia’s Southeast Sulawesi province is growing as conservation efforts intersect with mining activity.
- Moramo Bay is part of the Coral Triangle, one of the world’s richest marine biodiversity regions, and provides habitat for humphead wrasse and other protected species.
- Researchers and officials say the health of its coral reefs and marine life is increasingly under scrutiny as development expands around the conservation area.

Damselfish-assisted repair of wounded corals surprises scientists
- A new study finds that a coral-associated damselfish may help hasten the healing of wounded corals.
- The research showed a 55% faster recovery rate from larger coral wounds in the presence of damselfish, and a 38% faster rate of healing for smaller wounds.
- Algae living within wounded corals exhibited decreased photosynthetic efficiency, an energy source vital to coral healing, when damselfish were absent.
- Scientists say the findings could inform conservation management plans, focusing more attention on preserving fish habitats to better protect corals.

Turning the tables on invasive lionfish: How Honduran divers are fighting back
TELA, Honduras — Mario never set out to become a lionfish hunter. An engineer by training and founder of the local dive center Tela Divers, he simply wanted to do something about the growing number of invasive lionfish appearing on the reef where he learned to dive. Native to the Indo-Pacific and thought to have […]
Global sea surface temperatures reach a record high, again
Global sea surface temperatures have reached a record high, raising serious concerns for global Earth systems, according to new data released by the European Union’s Copernicus Climate Change Service (C3S). On Aug. 22, the daily global average sea surface temperature, outside polar regions, reached 21.1° Celsius (69.98° Fahrenheit), exceeding the previous record set in March […]
Blast fishing destroys reefs. Underwater microphones can help detect it
- Once home to a pristine and vibrant network of coral reefs, the Spermonde Archipelago off the coast of South Sulawesi in Indonesia has had its coral decimated by the illegal practice of blast fishing, in which improvised explosives are tossed into the sea to kill and stun fish en masse.
- A new study harnesses acoustic data to produce what is likely the first rigorous estimate of the frequency and intensity of bomb fishing in the archipelago.
- Using low-cost microphones and an easy-to-run algorithm, the researchers detected more than 3,500 so-called fish bombs going off in their study area within the archipelago — an average of 23 blasts a day, or almost one every hour.
- The scientists believe their approach could help communities and NGOs around the world design targeted interventions to combat the practice, which can devastate not only reefs but the broader marine ecosystems.

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

Local knowledge guides rediscovery of spinach pipefish, not seen in four decades
- Scientists have rediscovered spinach pipefish, a freshwater species endemic to Papua New Guinea’s Sepik River, not seen in nearly 40 years.
- The discovery came during a two-week survey led by local scientists and community members. Local fisherwoman Helen Asu netted two spinach pipefish, which scientists sent to experts for confirmation of the taxonomy.
- Scientists say the rediscovery offers hope that populations of the little-known, elusive fish still survive and provides an opportunity to understand more about its life cycle, habitat and ecology.
- The discovery highlights the importance of combining local knowledge with scientific research.

Nepal pushes for hydropower in protected areas through legal grey area
- Nepal’s government is allowing hydropower development inside protected areas, despite a January 2025 Supreme Court ruling that invalidates the legal provision for this activity.
- With the court’s full verdict still unpublished, the government has interpreted the ruling and continued to issue land-use and environmental permits.
- Mongabay’s investigation finds that 10 private hydropower projects, totaling more than 360 MW, have received permits since January 2026, affecting about 85 hectares across the Annapurna, Gaurishankar and Kanchanjunga protected areas, and the buffer zones of Makalu Barun and Langtang national parks.
- Officials say they are relying on 2023 guidelines and cabinet decisions covering projects licensed before July 2024, while the country’s wildlife department has continued approving feasibility studies, environmental assessments and transmission lines in protected-area buffer zones.

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

Tapirs, bats and nests: How plastic infiltrates Amazonian wildlife
- Studies have found microplastics in various species of Amazonian wildlife, including fish, tapirs, crabs and bats, even within protected areas far from major urban centers.
- Contamination spreads through multiple routes, traveling from small forest streams known as igarapés to the mouth of the Amazon River, where birds are building “blue nests” out of plastic debris.
- Although the toxic effects on animals remain poorly understood, data show that microplastics cross between aquatic and terrestrial ecosystems, potentially impacting the entire food chain.

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

100 species on the brink get a $200m conservation lifeline
Recovery projects for 100 critically endangered and extinct-in-the-wild species across the world are set to receive new funding under a conservation initiative announced Aug. 4. Re:wild and the Bezos Earth Fund, both U.S.-based environmental organizations, created the Phoenix Species Project and committed $100 million each, for a total of $200 million, to the project. The […]
Illegal mining threatens Ghana’s first marine protected area
- Illegal gold mining in Ghana’s Greater Cape Three Points Forest Reserve threatens vulnerable and endangered species in the protected forest, say conservationists.
- Sediment and toxic chemicals from the mining also threaten the adjacent waters of a newly declared marine protected area just offshore.
- Conservation NGOs want the government to act against illegal miners, including establishing permanent camps in the forest to protect a wider area.

Gabon ends fisheries partnership agreement with EU
Gabon has ended its 19-year fisheries partnership with the European Union, which allowed EU industrial vessels to target tuna in Gabonese waters in exchange for payment, arguing the agreement no longer serves the country’s economic interests. The decision follows a June 2025 Council of Ministers meeting at which the government announced it would seek to […]
In Amazon rivers, fish breathe and ingest plastics
- Following proof of the presence of microplastics in Amazonian rivers, streams and lakes, researchers are investigating how these particles affect fish health and physiology.
- A study highlights the risks associated with microplastics in the air-breathing organs of the pirarucu, a giant fish that must rise to the surface to breathe.
- Studies conducted with Amazonian fish show microplastics in their gills and digestive tracts, and experiments with the tamoatá point to increased stress and weight loss.
- Scientists warn of risks to human health in a region where fish is a dietary staple; in Brazil’s Amazonas state, average annual consumption is 14 kilos per person, five times the national average.

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

Four Pacific nations are planning one of the world’s largest ocean corridors
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Four Melanesian countries are planning a network of marine reserves across one of the world’s richest stretches of ocean. Papua New Guinea, Vanuatu, and Fiji announced the Melanesian Ocean Corridor of Reserves in May. Solomon Islands joined in […]
Introduced fish thrive amid Kashmir’s freshwater habitat degradation
Native fish in the lakes and rivers of India’s Kashmir Valley are under increasing pressure from pollution, habitat loss, dam construction and other human activities, a recent review finds. These same threats are also likely giving exotic fish introduced to these freshwater habitats an edge, researchers say. “Our indigenous fishes are becoming vulnerable, endangered and […]
Drifting tuna fishing gear enter half of marine protected areas: study
- A global study estimates that drifting fish aggregating devices, or dFADs, affect more than half of the world’s protected marine area.
- Researchers documented at least 6,324 dFAD strandings across 174 protected areas in 53 maritime jurisdictions over a period spanning 2007-2023.
- The analysis found no clear evidence that fishing fleets systematically concentrate dFAD fishing around large marine protected areas.
- Researchers and an independent fisheries expert are calling for stronger limits on dFAD deployments, better tracking and for companies to have greater responsibility for retrieving lost devices.

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

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

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

Thai MP calls for new committee to scrutinize AI data centers’ environmental impact
- A Thai member of parliament has called for the formation of a new committee to scrutinize the development of new data centers.
- Experts have warned that Thailand needs to find a balance between economic development and the water and energy resources required to fuel data centers.
- Despite these concerns, international tech companies are spending billions of dollars on data centers in Thailand, sparking fears over water scarcity and energy infrastructure.

Winners of the annual Mangrove Photography Awards: See the photos
In celebration of World Mangrove Day on July 26, the U.S.-based Mangrove Action Project (MAP) has announced the winners of its 12th annual photography awards. “Mangroves are the underdog. They will never be as glamorous as the Amazon rainforest or coral reefs. But through photography we can change that narrative, and intrigue people by showing […]
New treaty promises safer conditions for Indonesia’s fishing crews
- Indonesia has ratified the ILO Work in Fishing Convention (ILO 188), committing to stronger protections for fishing crews, including safer working conditions, fairer pay and better access to health care.
- Labor groups say the convention could close long-standing legal gaps that have left many domestic fishing workers vulnerable to poor conditions and weak oversight.
- Experts say stronger labor standards could also help curb illegal fishing and boost the credibility of Indonesian seafood exports in markets with strict sustainability requirements.
- The biggest challenge now is implementation, with the government facing a year to update regulations and improve enforcement, training, and support for the fishing industry.

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

Scientists call on countries to act on ‘forgotten’ sawfish teeth trade
- Teeth of critically endangered sawfish species continue to be used as cockfighting spurs in Latin America despite bans from cockfighting organizations, a new study found.
- Researchers interviewed cockfighting practitioners in Peru, where the sport is widely prevalent, and leaders from cockfighting associations in Peru, Mexico, Ecuador and Puerto Rico to understand the dynamics of this illegal trade.
- The study found sawfish teeth are sold for anywhere between $25 and $400 per pair, making them some of the most valuable wildlife products. Peru, Ecuador, Costa Rica, Brazil and Colombia supply most of the teeth, while Peru tops the list of consumers.
- All commercial international trade in sawfish is prohibited under CITES, and the fish is a protected species across Latin America. Scientists call on countries to enforce their laws and on CITES to act against hidden illicit trade.

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

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

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

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

Kent Carpenter spent half a century counting the life of Philippine reefs
- Kent E. Carpenter spent more than 50 years studying the fish, reefs, and marine biodiversity of the Philippines.
- His mapping of 2,983 species helped identify the central Philippines as the “Center of the Center” of marine shore-fish biodiversity. He combined taxonomy, genetics, conservation, teaching, and policy work to document both the richness of marine life and the pressures reducing it.
- At 73, he was still conducting field research and contributing to new surveys of Philippine reefs.
- Carpenter was shot dead at his home in Sibulan, Negros Oriental, on July 12th. An investigation is under way, according to authorities.

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

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

Like wolves, non-native lake trout have radically altered Yellowstone ecosystems (commentary)
- The 1995 reintroduction of wolves to Yellowstone National Park is a well-known conservation story, where the native predators were observed to return balance to the ecosystem.
- In opposite fashion, non-native lake trout that have become established in Yellowstone Lake are now outcompeting native cutthroat trout and seriously altering the overall ecosystem, both in and beyond the lake, and largely unseen.
- “We see animals moving through valleys [but] do not see connections breaking between lakes, streams, and the surrounding landscape,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

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

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

Brazil’s expanding offshore oil frontier puts biodiversity at risk: study
- Fossil fuel exploration off the northeast coast of Brazil presents a greater cumulative risk of oil spills than previously expected, according to new modeling.
- Seagrass meadows and deep-water reefs in the Potiguar Basin are at greatest risk, as well as portions of the coasts of Ceará, Rio Grande do Norte and Amapá states.
- As the Brazilian government is pursuing rapid expansion of oil exploration in the region, researchers recommend prioritizing preparedness for emergencies where pollution would likely spread, and expanding Marine Protected Areas (MPAs) in low-risk areas.
- Campaigners worry that MPAs might restrict local fishing communities or be implemented too slowly.

Declining carp fishes in Bangladesh’s Kaptai Lake leave small-scale fishers struggling
- Kaptai Lake is one of Bangladesh’s largest inland fish hubs, supporting the livelihoods of more than 27,000 registered fishers in the Chittagong Hill Tracts.
- Over the past several years, catches of high value carp fishes have declined sharply, forcing many small-scale fishers to abandon or supplement the ancestral profession.
- Researchers said carp species depend on specific spawning conditions including suitable breeding grounds. But the lake’s major breeding areas have been degraded, while overharvesting has further reduced the chances of natural recovery.
- Experts warn that without restoring breeding grounds, increasing carp fry stocking and improving fisheries management, the decline could continue, which would deepen economic pressure on small-scale fishers.

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

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

As Amazon oil drilling begins, scientists warn of risks to a little-known reef
- Brazilian state oil and gas company Petrobras has started drilling in the Equatorial Margin after years of political, scientific and environmental disputes over the risks posed by oil exploration at the mouth of the Amazon River.
- Researchers warn that the Amazon Reef system harbors a wealth of biodiversity and has not been widely studied, despite being close to Petrobras’s exploration block.
- Scientists disagree about the composition and extent of the Amazonian reefs, while environmentalists denounce attempts to downplay their ecological importance.
- Experts warn that an oil spill could reach mangroves, small-scale fisheries, and even neighboring countries, due to strong marine currents in the area.

São Tomé declares first two of eight planned marine protected areas
The West African island nation of São Tomé and Príncipe has formally designated its first two protected sites off its coast. This comes less than a year after presenting its plans to establish a national network of eight marine protected areas (MPAs) covering 93 square kilometers (36 square miles) in the Gulf of Guinea. The two […]
Women patrol Tanzania’s Pemba waters in a community-led push to protect the sea
- More than 1.8 million people live in Zanzibar, the semi-autonomous archipelago that united with Tanganyika in 1964 to form present-day Tanzania.
- Of Zanzibar’s population, roughly 550,000 people live on Pemba Island, one of its two main islands, where many households depend directly on the surrounding marine ecosystem for food, income, and livelihoods.
- Across the island, a community-led approach to marine resource management is taking root. Local communities are organized through Shehia Fisheries Committees and Collaborative Management Groups, which develop and implement rules governing the use of marine resources, including fisheries and locally managed conservation areas.
- Enforcing those rules, however, is not always straightforward. Community patrol teams often lack the legal authority needed to take action against offenders. In a largely Muslim society where marine patrols have traditionally been dominated by men, women are increasingly joining these teams to help monitor fishing activities and encourage compliance.

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

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

Our Ocean Conference in Kenya ends with $6.4 billion in pledges, review of past promises
- Governments, nonprofits, institutions and the private sector made more than 300 voluntary commitments and mobilized $6.4 billion for ocean conservation at the Our Ocean Conference in Mombasa, which closed June 18. It was the first time the annual gathering took place in Africa.
- The conference host, Kenya, laid out more than 40 commitments backed by more than $1 billion in finance for the expansion of marine protected areas, fisheries monitoring, climate finance and blue economy.
- With less than five years remaining to meet the goal of protecting 30% of the world’s oceans by 2030, a lot of attention was on governments to accelerate the process, but experts continued to call for strengthening of existing protections alongside expansions.
- Between 2014 and now, more than 3,200 commitments totaling $176 billion have been made at these conferences, and about 85% of those commitments have been fulfilled or are in the process.

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

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

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

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

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

To help combat illegal fishing, 15 countries commit to sharing fisheries data
Fifteen countries from Africa, Asia, Latin America and Europe adopted the Mombasa Declaration on June 17, 2026. Together, they committed to advance global fisheries transparency and strengthen efforts to combat illegal, unreported and unregulated (IUU) fishing. The declaration was adopted during the 11th meeting of the international Our Ocean Conference, held in Mombasa, Kenya. Africa […]
New walking shark discovered in Papua New Guinea
Researchers have described a new-to-science species of walking shark, which lives in the remote, shallow waters off southeastern Papua New Guinea. The newly named Dudgeon’s walking shark (Hemiscyllium dudgeonae) is a type of epaulette shark, a group of small sharks famous for their ability to use their fins to “walk” when stranded in tidal shallows. […]
Africa’s community-led marine organizations on which 30×30 depends
- More than 5,000 delegates are gathering in the Kenyan coastal city of Mombasa for a major global conference on the future of the oceans.
- At the heart of the discussions is ocean governance and the global push to meet the 30×30 target — protecting 30% of the world’s land, freshwater and oceans by 2030.
- But meeting that goal will depend not only on governments and international pledges, but also on community-led organizations doing the difficult work of conserving fragile marine ecosystems.
- Across Africa and around the world, thousands of grassroots groups are carrying out this work, often far from the spotlight, helping shape ocean conservation and blue economies that support local livelihoods. Mongabay spoke with representatives of four such organizations working across the continent from the Western Indian Ocean to Africa’s Atlantic coast.

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

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

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

A year on, Australia’s biggest harmful algal bloom continues to wreak havoc
- The largest and longest-lasting harmful algal bloom in Australia’s history, which started in early 2025, has potentially affected more than 20,000 square kilometers of ocean waters and about a third of the coasts in the state of South Australia.
- The algal bloom has devastated marine ecosystems and caused significant economic losses in the local fishing, aquaculture and tourism industries.
- As officials, researchers and communities grapple with its ecological, health and social impacts, the bloom has exposed a lack of preparedness at all levels of government for responding to future HABs.

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

Tuna are rebounding. The work is far from done.
Tuna offer a useful case study for World Ocean Day because their recovery has come through the least sentimental parts of conservation: quotas, enforcement, stock assessments, and years of difficult diplomacy. By the early 2010s, several tuna stocks were in serious trouble. Atlantic bluefin had become a marker of overfishing. Pacific bluefin had fallen to […]
Despite oil spills in Nigeria’s mangrove forests, Shell continued operations, documents show
- Documents disclosed as part of a lawsuit against UK-based oil company Shell show leadership continued operating a compromised pipeline in Nigeria’s Niger Delta despite knowing it posed a pollution risk in the surrounding coastal wetland environment.
- According to locals in Bille, a town near the pipeline, oil spills between 2011 and 2013 killed thousands of hectares of mangroves and aquatic life that rely on the wetland ecosystem, impacting people who depend on fishing.
- Shell said organized criminal gangs were responsible for the spills and that shutting down the pipeline and removing illegal connections also came with security risks.
- The Niger Delta region is a globally important biodiversity hotspot, hosting four Ramsar Wetlands and the largest mangrove forest in Africa.

Indigenous communities in eastern Indonesia revive systems for marine protection
Across the small islands of eastern Indonesia that lie within the Wallacea region, one of the world’s richest marine biodiversity regions, coastal communities are reviving ancient customary systems to safeguard marine ecosystems from destructive fishing and habitat loss. This movement is the centerpiece of Jejak Wallacea, a recent documentary highlighting how local empowerment can succeed […]
Offshore wind power cables can affect sensory system of sharks and rays: studies
- A series of studies found that electromagnetic fields from offshore-wind farm cables can trigger various effects in bottom-dwelling sharks and rays depending on species and life stage.
- Experiments on small-spotted catsharks and thornback rays showed behavioral and developmental responses.
- The researchers concluded that electromagnetic fields may increase predation risk during early development by altering natural behaviors linked to predator avoidance.
- eDNA surveys detected multiple shark and ray species inside offshore wind farms, suggesting they may serve as potential refuge areas, though major knowledge gaps remain.

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.

Europe removes record number of dams in 2025 to restore rivers, help species
A massive slab of wartime concrete blocked the Pčinja River in Kumanovo, North Macedonia for more than 70 years. A 53-meter-long and 30-meter-wide (174 by 98 feet) structure of reinforced concrete packed with salvaged railway steel impeded the free flow of water and fish for at least 70 kilometers (44 miles) upstream. It was considered […]
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.

New species of ghost pipefish named after Sesame Street character found in Australia
It’s “hairy,” bright orange or red and “exceptional” at camouflaging. Meet the hairy ghost pipefish, whose recent formal description demonstrates that even well-studied marine environments like the Great Barrier Reef still hold remarkable secrets for science. In a recent study, researchers shared the name of the ghost pipefish, Solenostomus snuffleupagus, for its “conspicuously shaggy appearance,” […]
Iceland must protect wild salmon and reject new aquaculture legislation (commentary)
- Aquaculture and other factors like climate change pose a potentially mortal threat to wild Atlantic salmon, so a new bill in the Icelandic parliament should be rejected, Patagonia founder Yvon Chouinard argues in a new op-ed.
- More than 65% of Icelanders polled agree with him in opposing open-net salmon farming, which the bill would allow to expand despite the fact that it employs a small fraction of those working in the tourism sector, and which relies heavily on the nation’s natural beauty and healthy wildlife populations.
- “Icelandic ministers can listen to reason and citizens and set an example of responsibility, rather than giving in to the worldwide aquaculture industry,” Chouinard writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

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.

Kenyan communities protest planned nuclear plant near Lake Victoria
On May 21, residents of Sakwa, in southeastern Kenya, gathered to protest the government’s plan to install a nuclear power plant near their homes, along Lake Victoria. Sakwa, in Siaya County, is home to the Luo tribe and lies along the shores of Africa’s largest freshwater lake, which Kenya shares with Uganda and Tanzania. In […]
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.

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.

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

European bottom trawling costs billions every year in climate impacts, study finds
Europe’s fishing industry makes around 180 million euros ($210 million) every year in profits from bottom trawling, which involves dragging heavy fishing gear along seabeds. But a new study found when climate costs associated with the practice are calculated, society is paying a price up to 90 times higher than the fishing industry profits. “Bottom […]
Egyptian teens use robots for ‘smarter and more responsive’ way to protect Earth
- A team of Egyptian students was among five from Africa shortlisted for this year’s Earth Prize, which recognizes the efforts of 13- to 19-year-olds offering innovative solutions to pressing environmental challenges.
- The “TerraSkipper” robot they designed is inspired by the real mudskipper fish, with a body and feet that “skip” through wet, salty and degraded farmland, collecting data on soil conditions like salinity and pH levels.
- The goal is not only to build the prototype, “but to contribute to a smarter and more responsive way of protecting our planet,” 16-year-old Mustafa Mohammed, one of the team members, told Mongabay.

Seabed life triples after bottom trawling ban in Scotland protected area
Nearly a decade since Scotland established the South Arran Marine Protected Area and banned bottom trawling across much of it, life on the seafloor has thrived, a new study has found. Scientists surveying the area found three times more seabed organisms and twice as many species compared to nearby unprotected waters. “What looks like […]
At world’s largest shark conference, scientists warn of a grim outlook across the board
- Hundreds of researchers and conservationists met in Colombo from May 4-8 for Sharks International, held once every four years.
- Major topics at the conference included the trade in shark and ray meat, reducing shark bycatch, and the use of new technologies in conservation.
- Participants also highlighted innovative programs that encourage community-based conservation, and grappled with the contentious topic of closing fisheries to aid recovery of threatened species.

In eastern Indonesia, communities revive customary systems to protect the seas
- A new documentary, “Jejak Wallacea,” highlights how coastal communities across eastern Indonesia are reviving customary marine management systems to protect ecosystems threatened by destructive fishing, turtle hunting and habitat loss.
- Communities featured in the film use locally rooted approaches including seasonal fishing closures, turtle hatcheries, mangrove restoration, customary sanctions and community patrols to manage reefs, fisheries and coastal forests.
- Conservation groups behind the project say community-led systems rooted in Indigenous and local knowledge can succeed where top-down conservation models and formal protected areas alone often fall short.
- The initiatives have helped protect species including sea turtles, dugongs and thresher sharks, but organizers say long-term success depends on stronger government recognition and support for community-based conservation.

Who are the women sustaining luxury fishing in Brazil’s Pantanal?
- In the heart of the Pantanal wetland, women from riverine communities spend up to 12 hours a day in murky waters, surrounded by caimans and snakes, to gather live bait that feeds a multimillion-dollar fishing tourism industry.
- Sportfishing in the Pantanal generates around $20 million a year, but the gatherers receive only a few cents for each piece of bait.
- During the close season, from November to February, when fishing is banned, they are supposed to receive compensation from the state; but this season there was still no payment as of early February.
- According to government data, women make up 40% of professional fishers in Brazil’s two Pantanal states, and they do most bait collection in the biome.

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

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

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

With its first marine reserve, Ghana protects its ocean to secure its future (commentary)
- Last month, Ghana made news when it declared its first marine reserve and sited it in one of the nation’s most ecologically and biologically significant marine environments.
- Ghana’s minister for fisheries and aquaculture explains in a new commentary that the Greater Cape Three Points reserve will help restore marine ecosystems and protect the livelihoods of 21 coastal communities, while advancing the nation’s 30×30 conservation goal ahead of next month’s Our Ocean Conference in Kenya.
- “We urge governments everywhere to follow in Ghana’s footsteps to protect more of our ocean, invest in effective management, and ensure communities are at the heart of these efforts,” the minister writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

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

Tierney Thys, marine biologist and interpreter of the sunfish
- Tierney Thys spent decades studying the giant ocean sunfish, using its improbable form to ask broader questions about life in the open ocean.
- Trained as a marine biologist, she moved between research, filmmaking, and public storytelling, helping make complex ecological processes accessible to wider audiences.
- In later years, her work extended beyond the sea, linking issues such as textiles and microplastics back to ocean health.
- Across her career, she returned to a central concern: how people come to value the natural world, and what sustains that commitment over time.

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

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

Cocaine exposure drives salmon to alter movements
Young Atlantic salmon exposed to cocaine and its breakdown product, benzoylecgonine, swim farther and more widely in the wild, a new study shows. This behavioral change can put them in risky situations, researchers say. “[T]he effects of illicit drug pollution on aquatic wildlife is not just a laboratory finding — it can measurably alter wildlife […]
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.

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 […]
Oil spill continues in Gulf of Mexico vulnerable habitats, while Pemex admits fault
- An oil spill has contaminated 933 kilometers (about 580 miles) of shoreline along the western Gulf of Mexico, impacting the Mexican states of Veracruz, Tamaulipas, Campeche and Tabasco in eastern Mexico.
- After two months of contradictory theories about what could have caused the spill, Mexico’s national oil company, Pemex, admitted the spill was caused by a leak in one of its pipelines.
- Local communities have had to reduce or stop their fishing and ecotourism activities due to a lack of information from authorities about the risks of coming into contact with the water, and despite a government-led cleanup, residents continue to document damages to the environment, such as oil-slicked vegetation and intoxicated or dead fauna.
- Conservationists say the containment of the spill is urgent for the protection of more than 1,000 marine species, among them, endangered Kemp’s ridley sea turtles whose nesting season is underway on the beaches of northern Veracruz and Tamaulipas.

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

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

Landmark US Magnuson-Stevens fisheries law turns 50 amid budget cut concerns
April 13 marked the 50th anniversary of the U.S. Magnuson-Stevens Act (MSA), a landmark conservation law credited with saving numerous U.S. fisheries from collapse and protecting vital ocean habitats. Despite decades of success, conservationists warn that recent federal funding cuts could undermine those gains. The MSA was passed in 1976, in the same decade the […]
In Tasmania, the mines have closed but the rivers remember
- Legacy copper mining in Tasmania, carried out for more than 100 years, has left parts of the King River ecosystem severely degraded, with scientists describing sections as “biologically dead” due to acid mine drainage and metal contamination.
- Globally, legacy mine waste has polluted hundreds of thousands of miles of rivers, exposing an estimated 23 million people to toxic metals, mostly through long-term sediment contamination rather than major disasters.
- Long-closed mines, which often operated with minimal or no environmental oversight, continue to leach waste from quarry and mine sites and tailings piles, causing long-term and ongoing contamination of rivers, streambeds and floodplains. Remediation across widely polluted landscapes is difficult and costly to carry out.
- Tasmania’s rivers are now a test case for the world: Despite decades of research and mitigation efforts, legacy pollution persists there, offering a warning as demand for critical minerals accelerates globally, with large amounts of copper and other metals required for electric vehicles, AI data center servers and other uses.

From carp to hippos, 43% of large freshwater animal species spread far beyond native ranges
From fish and turtles, to hippos and crocodiles, about 43% of all known large freshwater animal species have been deliberately introduced into ecosystems outside their native ranges, a recent study finds. Most species were introduced to boost fisheries, food security or tourism, but many have had unintended consequences for local wildlife, habitats and people. Fengzhi […]
Ghana declares its first marine protected area
Ghana has declared its first marine protected area after more than 15 years of efforts to bolster marine conservation and safeguard its depleting fish stocks. Vice President Naana Jane Opoku-Agyemang announced the creation of the MPA on April 14. It marks a “historic moment,” according to Ghana’s fisheries commission, Benjamin Campion. The designated area covers […]
In northern Kenya, a shifting Lake Turkana reshapes traditional livelihoods
- According to Kenya’s environment ministry, water levels in Lake Turkana have risen by several meters in the past decade, expanding its total surface area by around 10%.
- The rise, mainly caused by increased rainfall far upstream, has affected communities and infrastructure on the lake’s shores, as well as disrupted fishing in its changing waters.
- Extended drought in surrounding areas has drawn thousands of new fishers to Lake Turkana, sometimes sparking conflict.
- The people who have lived here the longest are negotiating their survival in what a researcher calls “a system with many variables, both natural and human.”

Creating the North Atlantic’s largest MPA network: Interview with Azores President José Manuel Bolieiro
- In May, José Manuel Bolieiro, president of the Portuguese-administered Azores region, will be honored at the international Peter Benchley Ocean Awards, known as the “Oscars for the Ocean.”
- Bolieiro played a key role in the recent expansion of the archipelago’s existing ocean protections with the establishment of the Azores Marine Protected Areas Network, now the largest MPA network in the North Atlantic.
- He spoke to Mongabay about the importance of ensuring adequate funding and enforcement for the new MPA network, his hope that Portugal can be a global reference for ocean conservation, and how growing up in the Azores fostered his deep love of the sea.

How the US rebuilt a collapsed fishery
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. After this piece was published, we were informed that Aaron Longton had passed away. On the docks of Port Orford, a small fishing town on the southern coast of the U.S. state of Oregon, Aaron Longton runs a […]
EU citizens file complaint for delays in response to anti-shark fin campaign
The organizers of a campaign against shark finning in the European Union have filed a formal complaint against the EU Commission, accusing it of mishandling their case and missing deadlines. The European Citizens’ Initiative (ECI) is an EU tool that allow citizens to participate in policy-making. The ECI known as “Stop Finning – Stop the […]
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.

Microplastics found in fish in Tuvalu, a remote South Pacific nation
Tuvalu is a remote Polynesian nation made up of three reef islands and six atolls. Home to fewer than 11,000 people, Tuvalu is 1,100 kilometers (680 miles) from its nearest neighbor in Fiji. Yet dispite its isolation and small population, new research shows that the ocean ecosystems around Tuvalu are polluted with microplastics. A team of researchers […]
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.

Is the Galápagos damselfish extinct?
- A once-common reef fish in the Galápagos has not been seen since 1983, raising the question of whether it has already disappeared.
- A recent study by Jack Stein Grove and colleagues concludes the species is likely extinct, based on decades of failed searches and historical records.
- Its disappearance is linked to the severe 1982–83 El Niño, which disrupted the islands’ nutrient cycles and food webs.
- The case highlights how even well-known marine ecosystems can lose species quietly, with declines only becoming clear in hindsight.

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

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

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

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.

World Water Day: Earth’s freshwater reveals new species & faces mounting threats
Water covers most of our planet, yet less than 3% of it is freshwater and most of it is contained in glaciers, making it not readily usable. Contamination and overuse threaten the valuable supplies of freshwater that humans and other animals, especially aquatic organisms, depend on to live. On World Water Day, a United Nations […]
Contested Amazon dam called to review water flow as river ecosystem fails
- A federal court and Brazil’s environmental agency ordered the Belo Monte hydropower plant to revise the Xingu River’s water-sharing plan, a decade after its debut, but a legal stay blocks enforcement of the ruling.
- The plant’s water flow has been subject to several complaints, as low water levels in the Volta Grande do Xingu have dried flooded forests and rock habitats, disrupting fish and turtle reproduction and threatening endemic species.
- “Increasing the amount of water is the only solution to restore this ecosystem,” says Josiel Juruna, coordinator of an Indigenous-led monitoring program documenting the impacts.

Eight arrested as Europe cracks down on lucrative eel smuggling syndicates
- Authorities in France and Spain have arrested eight suspects tied to a cross-border syndicate, accused of trafficking critically endangered European eels.
- Investigators say more than 7 million juvenile glass eels, worth nearly 600,000 euros (690,000 dollars), were smuggled over two years’ time.
- The arrests follow a year-long joint probe by investigators from the two countries into illegal fishing and laundering of eel catches.
- The case highlights the scale of an illicit trade that persists despite bans and trade protections for the species.

A fish a day: More than 300 freshwater species described in 2025
Taxonomists described 309 new species of freshwater fish in 2025, according to a report released by SHOAL, the IUCN Freshwater Fish Specialist Group (FFSG) and the California Academy of Sciences (CAS). With nearly one new description each day of the year, the tally is the highest since 2017, and the third-highest since 1758, when scientists […]
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.

Marine biologist Edie Widder chases bioluminescence in new ‘Life Illuminated’ film
- The new documentary “A Life Illuminated” traces the career arc of U.S. marine biologist Edie Widder, an expert on bioluminescence who’s made headlines for decades.
- The film documents her team’s attempt to capture a remarkable deep-water phenomenon called “flashback” on camera. (Spoiler alert.)
- Bioluminescence serves a variety of functions for deep-sea creatures, and flashback may originate from bioluminescent bacteria on drifting organic matter, Widder said.
- “A Life Illuminated” will make its Washington, D.C., premiere on Mar. 19, the first night of the D.C. Environmental Film Festival, where Mongabay is a media partner.

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.

Belugas facing euthanasia at shuttered Canada theme park may find new homes in US
- In August 2025, Canada’s only entertainment park with cetaceans, Marineland of Canada, closed for good, prompting concern about the fate of 30 beluga whales and four dolphins remaining at the facility.
- After a plan to transfer them to a theme park in China was blocked by the Canadian government, Marineland called for euthanizing the animals. The Canadian government has now conditionally approved their possible transfer to four U.S. institutions.
- Keeping highly intelligent and social creatures in concrete-lined tanks adversely affects their health and well-being, experts say.
- With changing public perceptions and a growing number of countries, including Canada, banning the keeping and breeding of whales and dolphins, conservationists are calling for alternatives to house the more than 3,700 cetaceans in captivity worldwide, including building seaside sanctuaries.

Plastic, from home and abroad, spills into Türkiye’s waters
- Türkiye has become a major destination for plastic waste recycling, notably from Europe and the U.K. Most of this scrap heads to the roughly 180 waste facilities handling plastic in Adana province.
- But large quantities are dumped along riverbanks or escape the facilities through their wastewater and eventually flow downstream into the Mediterranean Sea.
- The resulting pollution is taking a toll on riverine and marine ecosystems, including important sea turtle nesting sites.
- Some experts say Türkiye should stop importing plastic altogether to stem the tide of pollution, but the government has said the recycling industry plays an important economic role.

Thai data center boom sparks fears of water shortage, air pollution
- Thailand is experiencing a rapid data center boom, with more than 70 projects planned or underway, many clustered in the industrial Eastern Economic Corridor.
- Residents and farmers in Chonburi and Rayong provinces say they fear the facilities will intensify water shortages and pollution in a region already struggling with industrial impacts.
- Data centers require large volumes of water for cooling and major electricity supply, raising concerns about wastewater contamination and increased burning of fossil fuels.
- Critics say the sector is expanding with little transparency or community consultation, leaving locals uncertain about environmental safeguards and benefits.

The promise and perils of the 1995 Mekong River Agreement (commentary)
- Thirty years after the 1995 Mekong Agreement, the treaty and the Mekong River Commission have failed to stop cumulative damage to the river from dams, sediment loss, sand mining and altered flows.
- Hydropower expansion and major projects such as Laos’s mainstream dams and Cambodia’s Funan Techo Canal are accelerating ecological decline, harming fisheries, sediment flows and the Tonle Sap–Mekong system despite consultation processes meant to prevent such impacts.
- “This is not cooperation,” the author writes of the agreement. “It is a rat race tearing the Mekong apart.”
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Cambodian market survey a snapshot of a resilient — but stressed — Mekong
- In February, an international team of researchers conducted a two-week survey of fish species sold in markets in the Mekong River towns of Stung Treng and Kratie in Cambodia.
- The survey builds on a benchmark set by a 1994 survey in Stung Treng, allowing scientists to detect patterns in the size and diversity of fish being pulled from the river.
- The team identified 130 species, compared with 113 in the 1994 survey; 46 species were newly documented, many of them linked to aquaculture, while 29 species documented in 1994 were not found.
- Survey members say the tally shows the resilience of the Mekong, especially in places like Stung Treng where it remains undammed, but also points to worrying trends such as smaller fish dominating catches.

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

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

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

Guinea-Bissau’s transitional government bans fish meal production
- On Jan. 29, the government of Guinea-Bissau issued a flat ban on fish meal production, citing threats to marine ecosystems and food security.
- In recent years, as West African coastal nations — most notably Mauritania — increasingly clamped down on the industry, Guinea-Bissau emerged as a new regional fish meal hub.
- The first Chinese-owned fish meal factory vessel arrived in its waters in October 2019, followed by a second one in May 2024; both were supplied by Turkish-flagged industrial purse seiners that had previously fished for fish meal factories in Mauritania.
- The production also expanded on shore: In April 2025, Guinea-Bissau’s then-president inaugurated a fish meal plant, and as of February 2026, at least one other facility was under construction.

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

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.

Ocean Equity Index aims to measure justice at sea
- Researchers have developed an Ocean Equity Index that seeks to measure how equitable ocean initiatives are based on 12 criteria.
- The index, which was introduced alongside an academic study, can be used by governments, companies and community or Indigenous groups; the authors hope its use will be institutionalized globally.
- Assessing equity quantitatively is challenging because of the subject’s complexity and because perspectives of equity vary widely across actor groups, experts say.

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.

Indigenous Ikoots community prepares to relocate as the Pacific floods their town
- On Mexico’s Pacific coast, sea level rise and infrastructure projects have eroded 8.4 meters of coastline per year since 1967.
- In the community of Cuauhtémoc, San Mateo del Mar, at least 900 Indigenous Ikoots people are increasingly affected by flooding, as homes and streets give way to the sea.
- The community voted to relocate in May 2025, but bureaucratic delays are hindering the process, and many lack the funds to leave the community on their own.

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.

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

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

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

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

‘Free for all’ — Dominican Republic withdraws trade protections, the latest blow to American eels’ future
- The Dominican Republic withdrew a proposal to regulate commercial trade of its American eels under CITES, an international wildlife trade treaty. Its decision came on the heels of a failed effort to end unsustainable trade in all freshwater eels at the November meeting of delegates from 184 nations and the European Union in Uzbekistan.
- Freshwater eels are in high demand as a culinary delicacy in East Asian cuisine, and juveniles are bought and sold both legally and on the black market for aquaculture. But illegal trade has soared in recent years.
- With unrelenting demand, European eels are now critically endangered. Their cousins, the American and Japanese eels, are endangered, with their numbers plummeting.
- Conservationists say the Dominican Republic’s failure to enact protections that would monitor trade is disappointing and further threatens the future of an imperiled species.

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.

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.

Malaysia lost 20% of its coral reefs in three years
Malaysia’s coral reefs are shrinking at a pace that is hard to ignore. According to the latest national survey by Reef Check Malaysia, about one-fifth of the country’s coral cover has been lost since 2022, a decline compressed into just three years. What had been gradual erosion now looks more like a slide. The 2025 […]
Whale sharks released from nets along India’s coast as fishers turn rescuers
- Once hunted and butchered for oil and meat, whale sharks (Rhincodon typus) are now being rescued by fishers along India’s western Arabian Sea coast.
- Since 2001, the nonprofit Wildlife Trust of India has been educating fishing communities about whale sharks, training fishers in safe disentanglement techniques and offering compensation for destroyed nets.
- During that time, more than a thousand whale sharks have been released from accidental entanglement in fishing nets along India’s west coast.
- However, experts say the compensation for rescues remains insufficient and that social security, insurance, training and livelihood-linked incentives should be offered to protect the fishers who engage in whale shark rescues.

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

‘Holy river’ carries industrial waste & sewage from Nepal to India
- The Sirsiya River, once central to daily life, agriculture and religious rituals in southern Nepal, is now heavily polluted with industrial waste and sewage, turning it into a public health hazard.
- Factories in Nepal’s industrial corridor discharge untreated effluents as weak enforcement, ineffective regulation and unimplemented wastewater plans allow pollution to persist.
- Pollution flows into Raxaul, India, contaminating water and harming crops, while residents on other side of the border say Indian efforts to treat local sewage can’t offset the influx from Nepal.

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.

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.

Sámi reindeer herders protest EU-backed graphite mine, fearing lost grazing ground
- Sweden has approved the EU-backed Nunasvaara South graphite mine by Australia-based battery anode and graphite company Talga Group on land Sámi reindeer herders use for winter grazing.
- The mining company told Mongabay it has designed the mine area to limit the impact on nature and it plans to shut down operations for six months of the year to allow reindeer to graze on their winter grounds.
- But Sámi residents, who depend on herding, told Mongabay they fear their reindeer will be displaced because their winter grazing grounds will be destroyed, and they criticize the company’s environmental safeguards.
- They also said the mine’s inclusion as a strategic project under the EU Critical Raw Minerals Act has allowed it to be fast-tracked without essential environmental safeguards and that the company has made little attempt to meaningfully communicate with affected communities.

In Nepal, the world’s smallest otter continues to elude researchers
- The Asian small-clawed otter was rediscovered in Nepal in 2024 after 185 years. Since then, however, it’s gone dark again, with no more confirmed sightings.
- Identifying the animal remains challenging due to its small size, dietary overlap with other carnivores, and resemblance to common species such as the crab-eating mongoose.
- Funding and logistical constraints impede targeted surveys, as conservation priorities in Nepal focus mainly on larger, charismatic species such as tigers and rhinos.
- Despite this, conservationists are already planning measures to reduce potential threats to the animal by including it into the national otter conservation action plan.

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.

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.

Earth’s freshwater fish face harsh new climate challenges, researchers warn
- Climate change is rapidly altering freshwater ecosystems — raising temperatures, altering flood pulses and oxygen levels — and driving complex, region-specific changes in how fish grow, migrate and survive.
- Long-term U.S. data show sharp declines in cold-water fish as streams and lakes warm, while warm-water species gain only slightly. Some cold-adapted species are now disappearing as deep waters cease being a cold refuge.
- From Africa to the Arctic, impacts are emerging, including stronger lake stratification, declining fisheries and rivers turning orange as thawing permafrost releases toxic metals. Declining freshwater fisheries increasingly put food security at risk, especially affecting diets and health in traditional and Indigenous communities.
- Scientists say management and conservation techniques rooted in past conditions no longer work. New approaches must anticipate shifting baselines as climate change rapidly accelerates.

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 […]
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.

The Amazon’s lakes are heating up at ‘alarming’ rate, research finds
Five out of 10 lakes in the central Amazon had daytime temperatures over 37° Celsius, (98.6° Fahrenheit) during the region’s 2023 extreme heat wave, a recent study found. One of the most well-known water bodies is Tefé Lake in Amazonas state, northern Brazil. In September and October 2023, 209 pink and grey river dolphins, roughly […]
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.

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.

New mapping reveals hidden mining boom in Laos that threatens the Mekong
- Satellite analysis has identified 517 suspected riverbank mines in Laos, many likely illegal, with clusters along key Mekong tributaries, raising fears of widespread, unmonitored contamination.
- Officials in Attapeu province confirmed illegal mining remains pervasive despite crackdowns, with most operations missing from official records and many linked to Vietnamese or Chinese supply chains.
- The mining surge, including gold and rare earth extraction, poses major risks to ecosystems and communities in the Mekong Basin, where water testing capacity is weak and signs of declining fish populations and polluted rivers are emerging.
- Researchers say Mekong countries must coordinate regionally and engage China, the main importer of the region’s mining output, while strengthening enforcement and environmental oversight to address a rapidly expanding, largely unregulated mining sector.

‘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.

New underwater acoustic camera identifies individual fish sounds, helping track threatened species
- More than 35,000 species of fish are believed to make sounds, but less than 3 percent of species have been recorded.
- A new audio and visual recording device allowed scientists to identify the most extensive collection of fish sounds ever documented under natural conditions.
- Labeling the unique sounds of fish will allow conservationists to better track the behaviors, locations, and populations of threatened fish species.

In Chocó, river defenders say race for energy transition threatens lifelines
- Colombia is looking to accelerate its energy transition amid growing international demand for strategic minerals. But activists from El Carmen de Atrato in Chocó, western Colombia, allege that El Roble, the country’s only active copper mine, is harming the environment and local community.
- The Atrato River, which flows beneath El Roble, was granted constitutional rights in 2016, yet activists raise long-standing concerns over water pollution, tailings dam risks and alleged failures to meet conservation commitments in the area surrounding the mine.
- Critics say the mine has been allowed to operate under antiquated environmental regulation, with a modern environmental licence still under review.
- El Roble rejects all allegations, stating it is a responsible business that complies with environmental regulations. The company says it is the primary source of employment in El Carmen and points to its track record of local investment and community projects.

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

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

Behind Sri Lanka’s ‘fish rain’ lies a web of migrations now blocked by rising dams
- Sri Lanka recently reported a “fish rain,” where fish were found far from water bodies after heavy rains; but rather than falling from the sky, experts say these were amphibious fish that “walked” overland after the rains, making a rare but real phenomenon appear mysterious.
- Events like this highlight the subtle yet vital migrations that many freshwater species undertake — from overland movements by climbing perch and snakeheads, to upstream monsoon breeding runs by small fishes, to the epic sea-to-river-to-sea journeys of eels navigating rocks, dams and reservoirs.
- Such migrations are ecological lifelines, linking wetlands, rivers and coastlines, enriching ecosystems (as with salmon), and ensuring the survival and reproduction of a wide range of freshwater species.
- But in Sri Lanka, a growing network of dams, mini-hydro barriers and irrigation weirs is fragmenting rivers and blocking these ancient routes; despite fish ladders being proposed by dam developers, they’re rarely built, leaving many species unable to complete migrations essential for their survival.

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.

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

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

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

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

Study maps whale shark stranding hotspots in Indonesia, highlights conservation needs
- A new study has identified whale shark stranding hotspots in Indonesia and linked them to seasonal ocean conditions, offering scientists a clearer picture of when and where risks are highest.
- The researchers found that most strandings involved juveniles and often occurred during upwelling seasons; they highlighted that human pressures such as fishing gear, ship traffic and pollution may further increase the danger.
- The study calls for stronger rescue networks, better community training, and international cooperation to improve survival rates and protect these migratory animals across the region.

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.

Photos: Drones help First Nations track down cold-water havens for salmon amid warming
- Indigenous fisheries association and river guardians, representing several Mi’kmaq nations in eastern Canada, have launched a drone-based thermal-mapping campaign to locate and protect cold-water refuges vital for threatened Atlantic salmon.
- Warming temperatures are pushing the Atlantic salmon beyond their ideal thermal tolerance, compounding existing pressures on the species, such as overfishing.
- Warming waters and declining river flows during droughts are impacting both the fisheries and the cultural lifeblood of Mi’kmaq society.
- Indigenous river guardians hope the project will pre-emptively shield cool-water habitats before key spawning and migration corridors become unviable.

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.

Researchers define the importance of the ‘circular seabird economy’
In a review article published in Nature Reviews Biodiversity, researchers have introduced a new term to describe the importance of seabirds across land and marine ecosystems: the circular seabird economy. Although seabirds spend most of their lives at sea, they return to land to breed, often forming colonies of thousands of individuals. This influx of […]
Healthy rivers, healthy people: A Brazil project links human & ecosystem well-being
- A night fishing trip 30 years ago showed Brazilian public health doctor Apolo Heringer the meaning of health: a clean river full of fish — a notion that inspired the Manuelzão Project to restore the Velhas River Basin in southeastern Brazil.
- The basin includes Belo Horizonte Metropolitan Region (BHMR), capital of Minas Gerais, the third-largest metropolitan region in Brazil and home to approximately 5.7 million people in 34 cities; here, the combination of high population density, inadequate urban planning and lack of infrastructure has damaged the rivers that cross the region.
- After sewage treatment plants began operating in the area, fish started returning to the waters; the dorado (Salminus franciscanus) was chosen as an indicator of good water quality since it needs a lot of oxygen to survive and polluted waters have low oxygen levels.
- Connections between the river, its health and people’s understanding are crucial to the Manuelzão Project and its goals for collective health.

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

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

It examines the competing interests reshaping Cambodia’s coast, […]
Belize’s blue reputation vs. reef reality: Marine conservation wins, and what’s missing (commentary)
- For over a year, journalists from Mongabay and Mongabay Latam have been digging into issues related to the Mesoamerican Reef, the Western Hemisphere’s largest barrier reef system, which runs from Mexico’s Yucatán through Belize and Guatemala to Honduras.
- As part of that effort, which involves exploring both problems and solutions, Mongabay founder Rhett Ayers Butler spoke to experts and reviewed many reports, scientific papers, and stories.
- With its early leadership and significant funding, Belize has emerged as a linchpin in Mesoamerican Reef conservation and fisheries management. This summary brings together what various experts have said—highlighting gaps, issues, and actionable recommendations as they relate to Belize.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Night dives reveal hidden alliances between young fish and larval anemones
- A new study, drawing on nighttime underwater photography, documented previously unknown “symbiotic associations” between juvenile fish and larval anemones, with some fish staying close to the anemones, and others carrying them around.
- The study suggests the fish may gain protection from predators by associating with the toxic anemones, while the anemones could benefit from being transported by the fish to new parts of the ocean.
- An outside expert also proposed that anemones might receive additional benefits, such as nutrients from the fish’s excretions or from food scraps left behind.
- All of the experts emphasized that more research is needed to fully understand the dynamics of these relationships.

UK fish stocks in trouble as catch limits exceed scientific advice: Report
Nearly half of the United Kingdom’s most commercially valuable fish populations are either overexploited, critically low or both, according to a new report warning that the government continues to set catch limits above scientific advice. The report, “Deep Decline,” by conservation nonprofit Oceana UK, found that 17 of 105 U.K. fish stocks are both overfished […]
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?

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 […]
Negro River study finds genetic damage in fish after oil spill
- Scientists assessed harmful effects on Amazonian fish after a barge capsized in 2013 with approximately 60,000 liters of petroleum asphalt cement in Manaus.
- Although the concentration of the contaminant decreased with rising water levels, the fish continued to exhibit effects of exposure three months after the accident, including DNA damage and neurotoxicity.
- The Negro River’s waters are rich in dissolved organic matter, which may increase the toxicity of the chemical compound.
- This research adds to other studies that attest to the harmful effects of oil on vertebrates, aquatic insects and plants in the Amazon, given the pressure for greater exploration in the region.

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.

Mining the deep-sea could further threaten endangered sharks and rays
- A new study indicates that deep-sea mining could threaten at least 30 species of sharks, rays and chimaeras, many of which are already at risk of extinction.
- The authors found that seabed sediment plumes and midwater discharges of wastewater from mining activities could cause a range of impacts on shark, ray and chimaera species, including, but not limited to, disruptions to breeding and foraging, alterations in vertical migration, and exposure to metal contamination.
- The authors recommend precautionary measures, including improved baseline monitoring, the development of protected zones, and discharging wastewater below below 2,000 m (about 6,600 ft).
- With companies planning to begin deep-sea mining in international waters as early as 2027, the authors say more research is urgently needed to understand the full ecological impact of this emerging industry on biodiversity.

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.

20 animal species on the road to recovery: IUCN Red List update
From three species of Arctic seals to more than half of all birds globally, several animals have slipped closer to extinction, according to the latest update of the IUCN Red List. However, 20 species have seen a positive change in their status: they’ve moved farther away from the threat of extinction, thanks to effective conservation […]
Losing Nemo: In the Red Sea, clownfish vanish as anemones bleach
- A 2023 marine heat wave in the central Red Sea caused 100% of monitored sea anemones to bleach, followed by the death of 94-100% of clownfish and 66-94% of the anemones across three surveyed reefs.
- The findings challenge the belief that Red Sea marine life, already adapted to naturally hot water, would be protected from climate change, showing instead that rising temperatures are pushing even these heat-adapted organisms past their survival limits
- While six other Indo-Pacific regions experienced similar bleaching events with anemone deaths below 3%, the Red Sea’s 78% mortality rate reveals that 22 degree heating weeks marks a critical breaking point where these ancient partnerships fall apart.
- Researchers are calling for more monitoring of anemones worldwide while Saudi Arabia responds with expanded conservation efforts, including the world’s largest coral nursery and experimental probiotics to help reef organisms survive heat stress.

First oarfish sighting in Sri Lanka highlights citizen science in marine protection
- Scientists have documented the first-ever record of an oarfish (Regalecus russellii) in Sri Lanka, a 2.6-meter (8.5-foot) specimen caught off the country’s western coast.
- The find expands the known distribution of oarfish into the Indian Ocean, offering a new baseline for studying this rarely seen deep-sea species.
- Meanwhile, another oarfish was recorded in India’s Tamil Nadu this year, while within 20 days, three oarfish have been recorded from Australia and New Zealand, puzzling naturalists.
- The importance of promoting citizen science and raising awareness among fishers is needed.

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

Will California’s marine mammal conservation success come undone?
- With protection, many of California’s marine mammals — including whales, sea lions and seals — have made remarkable recoveries over the last half-century since bipartisan passage of the U.S. Marine Mammal Protection Act.
- However, climate-linked changes have now pushed the gray whale population into a state of collapse.
- Despite comebacks, marine mammals face a plethora of threats from pathogens, pollutants — including oil and plastic — disappearing food and more.
- In California, people and institutions are fighting for marine mammals and ocean biodiversity, but federal protections could be substantially weakened if proposed amendments to the Act move ahead.

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.

Africa’s largest freshwater lake could be site of Kenya’s nuclear power plant
- The proposal to build a 1,000-MW nuclear power plant on Kenya’s southeastern coast has faced strong opposition from residents and environmental experts, who warn of potential harm to communities, fisheries and the environment.
- Government agencies are now holding consultations at another prospective location on the other side of the country, near Lake Victoria, Africa’s largest freshwater lake.
- Kenya’s energy needs today are met mostly from low-carbon sources, and the country is on track to achieve universal energy access by 2030, but authorities say nuclear power is needed to meet future development goals.
- Some experts, however, warn about the high costs, delays, and long-term environmental risks associated with nuclear power projects.

Philippines protects coral hotspot
The Philippines recently protected 61,204-hectares (151,200-acres) of the seas around Panaon Island, home to some of the healthiest and most climate-resilient coral reefs in the world. The waters are also rich in fish and host several threatened species such as the endangered whale shark (Rhincodon typus), the critically endangered hawksbill turtle (Eretmochelys imbricata), the endangered […]
Indonesia eyes seagrass zoning for blue carbon; experts urge community benefits
- Indonesia is moving to designate 17 seagrass habitats as national strategic areas for blue carbon, a plan that promises climate and community benefits but raises concerns over safeguards.
- The fisheries ministry says the zoning will help cut emissions, protect marine ecosystems and boost coastal livelihoods, with seagrass storing carbon far more effectively than rainforests.
- Experts welcome the initiative but warn it must avoid privatization, ensure fair benefit-sharing and guarantee transparent governance to prevent conflicts and elite capture.
- With Indonesia holding 11.5% of the world’s seagrass meadows, scientists stress the urgency of protection as the ecosystems vanish globally at alarming rates.

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.

From South America to Asia, seahorses vanish into trafficking pipeline
- In June 2025, Ecuadorian police seized a package containing almost 3,000 seahorses that were likely destined for Colombia.
- Most seahorses are caught in industrial and artisanal trawl nets as bycatch, but they are then funneled into a lucrative illegal trade.
- Researchers have identified the busiest trafficking routes: Peru to China, Hong Kong and Vietnam.
- Seahorses are in high demand for use in traditional Chinese medicine, and are also sold as trinkets and as exotic additions to aquariums.

Hope for the iconic Yangtze sturgeon (cartoon)
After losing two of the Yangtze River’s native wildlife icons — the baiji (a river dolphin) and the Chinese paddlefish — to dams and overfishing, and almost losing the Yangtze sturgeon, China seems to be taking measures to correct the course. The demolition of dams along the Chishui He, a major tributary of the Yangtze River, […]
Study spotlights West Papua habitat as whale sharks face increased pressures
- A new study shows the Bird’s Head Seascape in West Papua is a crucial nursery for juvenile whale sharks, where most sightings involved young males feeding around fishing platforms.
- Researchers documented 268 individuals over 13 years, with more than half showing injuries tied to human activity, raising concerns about fisheries, tourism and emerging mining pressures.
- Scientists warn that protecting these habitats with stricter rules and better management is essential for the survival and recovery of the endangered species.

Long-lost white shark tag traces remarkable journey from South Africa to SE Asia
- The discovery of a satellite tag from a subadult female white shark in Indonesia marks the first recorded connectivity of white shark movement between South Africa and Southeast Asia.
- The white sharks found in South Africa and Australia belong to different genetic pools, which makes the two populations distinct from one another, even though they share the same migratory route.
- The biggest threats facing white sharks in South Africa and Indonesia are unsustainable fishing, where the sharks become both the bycatch and main catch.
- While there are attempts to support local fishers to pioneer shark conservation instead of hunting them, such efforts are thwarted by lack of funding.

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.

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

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

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

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

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

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

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

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.

Researchers describe three new-to-science snailfish species off California coast
In 2019, researchers surveying the seafloor off the coast of California came upon three unusual species of small fishes with large heads: one with bumpy pink skin, and the other two both black in color. The team collected the fish using underwater research vehicles and later analyzed their DNA and bodies. Their analysis showed that […]

Scientists capture rare video of bumblebee catfish climbing waterfalls in Brazil
In November 2024, members of Brazil’s environmental military police and scientists observed a “massive aggregation” of small catfish making their way up waterfalls in Brazil. These first-of-their-kind observations of the rare bumblebee catfish likely migrating upstream to spawn were published in a recent paper. The researchers’ video footage shows thousands of bumblebee catfish (Rhyacoglanis paranensis), […]
Scientists reconfirm rare shark sightings after 50 years in PNG
In 1973, researchers scientifically described a species of shark based on a single specimen: a pregnant female caught a few years earlier by a fisherman near the mouth of the Gogol River in Astrolabe Bay, Papua New Guinea. They named this new-to-science species the sailback houndshark (Gogolia filewoodi). And then, for the next half-century, they […]
A ‘sea war’ brews off Gambia as desperate local fishermen attack foreign vessels, and each other
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 […]
Climate change is driving fish stocks from countries’ waters to the high seas: Study
- A new study found that more than half of the world’s straddling stocks will shift across the maritime borders between exclusive economic zones (EEZs) and the high seas by 2050.
- Most of these shifts will be into the high seas, where fisheries management is much more challenging and stocks are more likely to be overexploited.
- Among the most serious potential consequences is a loss of fisheries resources for many tropical countries that did little to create the climate crisis, including small island developing states in the Pacific Ocean.

Scientists warn ocean-based climate fixes lack rules and oversight
- Marine-climate interventions have received increased money and attention in recent years.
- While many projects and ideas may be well-intentioned, they’re generally not subject to strong governance or oversight, and they often pose risks of social and ecological harm, according to a new paper.
- The authors call for local, national and global rules that will make interventions “safe, equitable and effective.”

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.
