World Turtle Day: Important conservation wins amid turtle extinction crisis
World Turtle Day is celebrated every May 23 to raise awareness about the threats faced by turtles and tortoises. Turtles, tortoises and terrapins, which together make up the order Testudines, have evolved over millions of years, dating back to the Triassic period. However, recent reports show that more than half of the world’s 359 turtle […]
AI listens for endangered orcas to help reduce underwater noise exposure
Artificial intelligence is listening to orca calls in real time and helping to reduce their exposure to underwater noise. The effort is focused on an endangered orca subspecies in the Salish Sea, off the coasts of the northwestern U.S. and western Canada, reports Mongabay writer Abhishyant Kidangoor. The southern resident orcas (Orcinus orca ater), made […]
Norlan Pagal, fisherman and guardian of Tañon Strait, died on May 14th, aged 56
- Norlan Pagal spent more than a decade defending the waters of Tañon Strait from illegal fishing.
- He survived dynamite, beatings and a 2015 ambush that left him paralyzed from the waist down.
- From his wheelchair, he continued watching the sea with binoculars and reporting violations to patrols.
- His work helped inspire other fishers to protect their waters and earned him recognition as an Ocean Hero.

More than 1,000 uncharted coral reefs mapped in vast, understudied northern Australia
Scientists have layered hundreds of satellite images to reveal more than 1,000 previously uncharted coral reefs in the turbid waters of northern Australia. The number is comparable to the Great Barrier Reef, though many reefs are smaller in size, researchers say. The reefs of northern Australia, while probably known to locals, had previously largely remained […]
New conservation effort launched to protect coral reefs in Yap
Conservation groups have launched a new initiative to safeguard coral reefs in Yap, a state in the Federated States of Micronesia, through both scientific innovation and traditional stewardship. The Yap Resilience Hub, a partnership between The Nature Conservancy (TNC) and the Great Barrier Reef Foundation (GBRF), is a three-year project that seeks to support local […]
Ghost shark, carnivorous sponge among 1,000+ newly discovered marine species
The third year of a global Ocean Census has revealed 1,121 potentially new-to-science marine species, including a worm that lives inside a “glass castle,” a ghost shark, and a carnivorous sponge. The Ocean Census, launched in April 2023, aims to discover and describe marine life “at speed and at scale” before it is lost. The […]
Philippine fishing and Indigenous communities wary of clean energy boom in Marcos stronghold
- The Philippines is currently highly dependent on fossil fuels for energy generation, but the government has committed to reaching 50% renewables by 2050.
- The resulting energy boom — especially in Ilocos North, the president’s home province — has seen an influx of foreign investment, but also raised questions about who will bear the costs of the country’s energy transition.
- Fishers in Ilocos Norte say they worry that wind energy projects in their traditional fishing grounds will disrupt marine life and fishing routes.
- Inland, the Masamuyao Isneg Yapayao tribal council is trying to stop the expansion of a solar farm that officials say failed to obtain the tribe’s consent.

Monica Montefalcone, leading seagrass scientist, dies in Maldives diving accident, aged 51
- Monica Montefalcone, a University of Genoa marine ecologist and leading expert on Mediterranean Posidonia oceanica meadows, died in a diving accident in the Maldives at age 51.
- Her daughter, Giorgia Sommacal, 23, died with her, along with three other Italians, four of whom were connected to the University of Genoa.
- Montefalcone’s work linked field science, conservation practice and public understanding, especially through mapping, monitoring and restoring seagrass meadows and other coastal marine habitats.
- Colleagues and students remembered her as a demanding field scientist, generous teacher and clear communicator who helped younger researchers find their place in marine biology.

Marine conservation suffers when the ocean is not accessible to all, especially on remote islands (commentary)
- Coastal and marine systems across much of the world remain structurally inaccessible to persons with disabilities, older populations, and marginalized communities.
- If people protect what they value, and they value what they can experience, then marine conservation will be a low priority for these people, a new op-ed argues.
- “If the ocean is to be protected, it must first be experienced, but for millions of people, it remains fundamentally out of reach,” the author writes.

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

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.

Ocean philanthropy: small sums for a vast domain
- Ocean philanthropy remains small relative to the scale of the ocean itself, accounting for well under 1% of global charitable giving despite steady growth over the past decade.
- Funding is concentrated among a small group of foundations and continues to focus heavily on marine science, habitat protection, and fisheries, though climate-related ocean funding has risen sharply in recent years.
- Most ocean conservation funding needs lie not in creating protected areas, but in the long-term costs of management and enforcement, with current spending far below estimated requirements.
- Philanthropic funding often plays a catalytic role by supporting early-stage research, policy work, and financing mechanisms such as blue bonds and debt-for-nature swaps that can unlock larger pools of public and private capital.

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.

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.

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

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

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

One of the world’s largest deep-sea coral reefs discovered off Argentina
- Scientists have discovered what may be one of the world’s largest cold-water coral reef systems, located about 1,000 meters (3,300 feet) deep in Argentina’s territorial waters, with much of it remaining unmapped.
- The reef, dominated by the rare coral species Bathelia candida, hosts a surprisingly rich ecosystem, including dozens of deep-sea species new to science.
- Researchers found signs of human impact, including fishing debris and possible trawling damage, and worry the reef area might also be targeted for oil and gas exploration.
- The researchers are testing restoration techniques, including the installation of 3D-printed “artificial corals,” which they hope will encourage the rapid growth of new corals.

As global 30×30 goal lags, Colombia shows how progress can be made
- In 2022, nearly 200 nations pledged to protect and conserve 30% of terrestrial and marine areas by 2030 under Target 3 of the Kunming-Montreal Global Biodiversity Framework.
- Currently, 18% of land and inland waters, and 10% of marine and coastal areas are protected and conserved.
- Colombia, one of the world’s most biodiverse countries, has exceeded the global average, protecting and conserving 47% of marine and 26% of terrestrial areas.
- This has been achieved through new and expanded public and private protected areas, other area-based effective conservation measures (OECMs), and other means, including Heritage Colombia, an innovative “project for finance permanence” initiative.

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

Photos: A shark meat processing village and market in Indonesia’s Lombok
Shark meat has quietly surpassed shark fins in international trade volume and value. In East Lombok it sells for as little as 29 cents a skewer. Photojournalist Garry Lotulung documented the shark trade at Lombok’s Tanjung Luar fish market and nearby Rumbuk village, an important shark meat processing center. EAST LOMBOK, Indonesia — Indonesia consistently […]
Chile’s plan to protect another 10% of its ocean is stalled by the new government
The expansion of two vast Pacific marine parks near Chile has been suspended for six weeks, leaving protections for around 337,000 square kilometers (130,000 square miles) of ocean in limbo. Former President Gabriel Boric signed a decree creating marine parks Juan Fernández II and Nazca-Desventuradas II on March 10, his last day in office. Together […]
AI tool listens for endangered orcas in real time to reduce human disturbance
- An AI initiative is listening to southern resident orcas in real-time to help them steer clear of vessels and noisy coastal construction.
- OrcaHello builds on a network of underwater microphones to detect orcas and push out alerts that have helped pause coastal construction and redirect boat traffic as the orcas pass by.
- Southern resident orcas are considered an endangered subspecies, with only 76 remaining individuals.
- Major threats to the species include a decline in their food sources, primarily Chinook salmon, along with noise pollution and vessel traffic.

How marine flyways could help save the world’s declining seabird population
The routes taken by migratory birds, known as flyways, often cross vast expanses of ocean. Six of these marine flyways have now been formally recognized by the U.N.’s Convention on Migratory Species, at the suggestion of scientists who published their findings on these flyways in the British Ecological Society’s Journal of Applied Ecology. Tammy Davies, […]
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.

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

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 […]
Council recommends opening US Pacific marine monuments to commercial fishing
A U.S. fishing regulator recently recommended allowing commercial fishing across all four of the country’s Pacific marine national monuments. The Western Pacific Regional Fishery Management Council (Wespac) said the move is “about restoring sustainable fishing.” Conservationists and native peoples, however, say it will damage some of Earth’s most pristine ocean ecosystems. The monuments — Pacific […]
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.

In Indonesia, a coastal vine used as medicine now signals ecological decline
- The beach morning glory (Ipomoea pes-caprae) vine is widely used as a traditional medicine in the north of Indonesia’s Sulawesi Island, and in many tropical coastal communities, to treat common complaints, and by fishers to treat stings from venomous fish.
- In addition to its medicinal use, the plant, also known as bayhops, reinforces beaches by binding sand dunes, increasing the resilience of global coastlines to risks of abrasion and erosion.
- Beach morning glory is a ubiquitous crawling vine, but some communities in Sulawesi’s Gorontalo province say the medicinal plant has disappeared locally due to industrial development and infrastructure construction.

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

A French city cut its marine pollution — and its seagrass bounced back
- Neptune grass is generally regarded as the most ecologically important seagrass and shallow-water habitat in the Mediterranean Sea, where it is endemic. But the species has been in decline for many decades.
- A new study found that following the introduction of stronger environmental regulations and practices in the mid-to-late 1980s, Neptune grass (Posidonia oceanica) repopulated sampled sections of the waters off Marseille, France, over the ensuing four decades at rates that experts called “exceptional” and “remarkable.”
- The lead author said the study shows the value of passive restoration: letting seagrass meadows regrow on their own after removing the human-caused drivers of decline, rather than focusing on replanting or transplanting the species.

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

10% of the ocean is protected. Now just 20% more to go
- Data from the World Database on Protected and Conserved Areas (WDPCA) indicate that more than 10% of the ocean is now protected, marking a significant milestone for ocean conservation efforts.
- With a global goal to protect 30% of the ocean by 2030, experts warn that efforts must accelerate dramatically: An area roughly the size of the Indian Ocean must be protected within the next four years to meet the goal.
- While overall coverage is important, protection levels vary widely. For instance, only about 3.3% of the ocean is currently classified as fully or highly protected — and that number may even decrease.
- Experts have also raised concerns about the quality and effectiveness of many areas designated as “conserved,” which are now counted alongside traditional marine protected areas.

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.

American Samoa said ‘no’ to deep sea mining, Washington heard ‘faster’ (commentary)
- The U.S. government is moving fast to grant leases to corporations for deep sea mining in places like the territory of American Samoa: once issued, these are very difficult to rescind.
- Leaders there have weighed in against this lease on cultural and environmental grounds, but the federal agency in charge has merely acknowledged this dissent while continuing to move forward.
- “American Samoa is not a test case; it’s at risk of becoming the federal government’s blueprint” on deep-sea mining licensing, a new op-ed states.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Baby octopus in Argentina: Photo of the week
These eggs belong to a small octopus known in Argentinian Patagonia as pulperos. The Patagonian octopus (Octopus tehuelchus) is one of the more common octopus species in the region, but researchers still haven’t been able to determine its global conservation status, although reported catches in Patagonia have declined over the past 50 years. The photo […]
Singapore resort said to halt controversial dolphin sourcing, breeding
- Singapore’s Resorts World Sentosa is to end sourcing dolphins from the wild and has suspended a captive breeding program, according to sources.
- The company is assembling a team of experts to decide the future of more than 20 Indo-Pacific bottlenose dolphins, most of which were captured from the Solomon Islands in 2008 and 2009.
- The resort has maintained the dolphins are well cared for and the exhibit at Singapore’s Oceanarium serves educational and conservation purposes.
- Experts say that rehabilitation and release of the dolphins is possible, with transfer to a natural sea pen the first step for assessment.

Marine flyways are the missing map we can use to boost seabird conservation (commentary)
- At the 15th Conference of the Parties to the Convention on Migratory Species last week in Brazil, delegates formally established something scientists have long understood but never before mapped at a global scale: marine flyways used by seabirds.
- Seabirds are more than charismatic travelers along these routes, rather, they are indicators of ocean health and can guide conservationists to the most important areas for marine biodiversity.
- “Seabirds have been tracing these routes for millennia. They have shown us the map. Now it is our turn to follow it with urgency, ambition and a shared commitment to safeguarding the ocean that sustains us all,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Traditional protection proves more successful for clams in American Samoa
- A study found that on the most populated island in American Samoa, traditional village-based protections and remote sites had the highest density of giant clams — outperforming federally designated no-take zones in one case.
- The authors suggest that traditional community stewardship could offer a viable alternative to federal restrictions, especially in areas communities rely on for giant clam harvesting, while respecting traditional management practices.
- The giant clams, which are slow-growing, face threats from habitat degradation, ocean warming, watershed pollution and overharvesting.
- The NOAA National Fisheries Service proposed protections for several giant clam species in 2024 which could lead to a top-down ban on harvesting. Some sources say a blanket ban without including communities in conservation strategies would impact people who rely on harvesting.

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.

New strategy to reverse Kenya’s shark decline tries to bring fishers on board
- A new strategy by government agencies, scientists and coastal community members proposes a working plan of 19 goals to reverse the steep decline of sharks and rays in Kenya.
- As small-scale fishers have a lot of influence on the marine species’ populations, most of the goals directly involve fishers or try to get them on board to make the conservation strategy a success.
- Goals include alternative fishing gear, different livelihoods to reduce fishing pressure, increasing the number of locally managed marine areas, involvement of fishers in conservation decision-making and more effective enforcement.
- Community fishing representatives say they are on board with the plan but highlight that a few points, like concrete and viable alternative livelihoods and fishing methods, need to be offered to reach the conservation goals.

China’s deep-sea mining fleet may also track US submarines
A Mongabay and CNN investigation found the eight Chinese state-owned ships that conduct deep-sea mining research in China’s mining areas allocated by the International Seabed Authority (ISA) actually spent little time in these exploration areas, while spending much of their remaining time operating in militarily strategic waters. Many of these vessels are linked to the […]
PNG’s New Ireland coastal waters causing fish deaths, human sickness
- Communities on the east coast of Papua New Guinea’s New Ireland province report that contact with the seawater there has made people sick since December 2025; residents have also reported spikes in the number of dead fish and other marine life along the shoreline.
- A group of local and international NGOs has responded, providing help with sampling to determine the cause and raising money for the affected villages.
- New Ireland’s coastal communities depend on the sea for food, but government officials have warned against eating fish until the cause of the problems has been identified.
- Government ministries have been aware of the situation for at least two months, and while leaders say that tissue, water and soil samples have been collected, no results have been released yet.

Deep-sea mining rules face delays despite urgent push
Commercial deep-sea mining hasn’t yet begun, but it soon could — with the potential to reshape vast stretches of the ocean as companies move to extract minerals from the seafloor. However, this nascent industry lacks a set of international rules to govern it, and a recent meeting of the regulatory body charged with drafting one […]
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.

Brazil protects huge coastal area with endangered dolphins and megafauna fossils
Brazil’s federal government created a huge conservation area on March 6 to protect a critical biodiversity hotspot in the Atlantic Ocean. The newly created Albardão marine park and coastal environmental protected area are home to at least 25 endangered species and Pleistocene epoch megafauna fossils. The new national park is off the coast of Brazil’s […]
Why saving seagrass meadows could help save the world’s coastlines
- Seagrass is known for its blue carbon potential, but meadows also play an important role in coastal protection by helping reduce wave intensity and stabilizing sediments, both of which are key to reducing coastal erosion.
- Experts point out that seagrass brings multiple other benefits, such as improving water quality that helps the marine environment, including coral reefs.
- Yet seagrass meadows across the globe face declines due to multiple stressors, including climate change.
- Conservationists and researchers are working to restore meadows and help them become resilient to increasing ocean temperatures and potentially devastating marine heat waves.

If Florida reefs aren’t protected, storms will increase flooding & costs: Study
- Coral reefs absorb incoming waves, protecting shorelines from tropical storms.
- A recent Earth’s Future study examines flood risks from tropical storms to communities in Florida, if coral reefs keep degrading at current rates.
- The study finds that future coral reef degradation will increase the annual risk of flooding to people by 42% and to buildings by 47%.
- This increased degradation would predictably cause $412.5 million in damages to structures and economic disruption of $438.1 million annually.

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.

Sri Lankan waters under ‘close watch’ following wreckage of Iranian warship
- At least 90 bodies were recovered from the wreckage of the IRIS Dena, an Iranian warship that was torpedoed by a U.S. submarine on March 4.
- The Sri Lanka Navy has spotted oil patches and life rafts during the rescue mission but no oil spill reported so far.
- Maritime experts say Sri Lanka will have an opportunity to raise a claim for environmental damage following the sinking of the frigate.
- If the Indian Ocean island intends to seek damages, the government may have to claim environmental damages through an international tribunal, considering the frigate was sunk under conditions of war.

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.

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.

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.

Panama NGOs face lawsuits, asset seizures in fight over port construction
- Two environmental groups fighting the Puerto Barú project in Panama have been named in lawsuits claiming they defamed the developers and created public confusion about the project.
- The Center for Environmental Advocacy of Panama and the Adopt a Panama Rainforest Association (Adopta Bosque) say the port could damage mangroves and harm vulnerable shark and ray species.
- Both organizations have had their assets seized, including bank accounts and properties that serve as private nature reserves.

In Thailand, a coral cryobank tries to buy time for dying reefs
- Scientists in Phuket are freezing coral larvae and their symbiotic algae, aiming to create a “living seed bank” to preserve Thailand’s reef genetic diversity amid accelerating climate stress.
- Thailand’s reefs, home to more than 300 coral species, have experienced repeated mass bleaching events since 2022, with damage compounded by tourism pressure, wastewater runoff, sedimentation and overfishing.
- Researchers describe coral cryobanks as a form of “genetic insurance” and ex-situ conservation, but stress they can’t replace in-water protection and must be integrated into broader restoration and marine management strategies.
- Conservation experts say improving water quality, regulating tourism impacts and strengthening community-led marine protection are essential if preserved coral material is to be successfully restored to the wild.

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.

Scientists discover a new whale highway after tagging a pygmy blue whale by drone
- Scientists in Indonesia have tagged a pygmy blue whale for the first time using a drone.
- Data from the tag revealed a previously unknown path used by the species on its southern migration from Indonesia to the west coast of Australia.
- The biggest threats to the pygmy blue whale include ship strikes in busy shipping lanes, ocean noise pollution, and climate change.
- A team from Timor-Leste will now repeat the drone tagging protocol in their waters.

Coral bleaching: How warming seas are transforming the world’s reefs
- Mass coral bleaching occurs when unusually warm ocean temperatures disrupt the partnership between corals and the microscopic algae that supply most of their energy, leaving corals weakened and often leading to widespread mortality if heat stress persists.
- The 2014–2017 Global Coral Bleaching Event was the most severe on record, affecting more than half of the world’s reefs, and a new global bleaching event that began in 2023 suggests that large-scale damage is continuing as oceans warm.
- Bleaching interacts with other pressures — including ocean acidification, overfishing, pollution, coastal development, and destructive fishing — reducing reefs’ ability to recover and increasing the risk of long-term degradation.
- While conservation, restoration, and experimental interventions may help protect resilient reefs or buy time locally, scientists emphasize that limiting global warming is critical to preserving coral reefs as diverse, functioning ecosystems.

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.

In Kenya’s Jomvu Creek, women help restore a vanishing coast through crab farming
- On the outskirts of the coastal Kenyan city of Mombasa, a women’s organization in Jomvu Creek aims to transform livelihoods and the environment through mud crab farming.
- A blue economy grant is allowing the women to establish a crab-fattening enterprise and build a boardwalk through the creek, with hopes of boosting ecotourism.
- In a good month, the women’s crab sales amount to $310, meaningful income in an area where many had said they were living hand to mouth.
- Beyond income, the Jomvu women see themselves as caretakers of the creek, linking crab farming to mangrove restoration and planting nearly 1 million seedlings; the trees stabilize the shoreline, reduce erosion and create nursery habitats for fish and crabs.

‘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.

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

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

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

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

Seagrass restoration in Malaysia finds multi-species approach boosts recovery
- Seagrass restoration is increasingly recognized as crucial for addressing the twin crises of biodiversity loss and climate change.
- However, much remains unknown about the most effective techniques, especially in tropical ecosystems where long-term projects struggle for funding.
- A decade-long seagrass recovery program in Peninsular Malaysia has achieved high survival rates at a site heavily impacted by coastal development, raising hopes that degraded meadows can be revitalized.
- The study also identified several factors that can increase success, including: knowledge of the biology of local seagrass species, adapting methods to suit local environmental and physical conditions, and properly addressing the original drivers of decline.

Lower levels of PFAS ‘forever chemicals’ in North Atlantic whales show regulations work: Study
- North Atlantic pilot whales now have 60% lower concentrations of some legacy PFAS (forever chemicals) than they did a decade ago, according to a Harvard University-led study.
- This represents roughly a decade-long lag after major manufacturers began phasing out production of the most problematic legacy PFAS in the early 2000s due to toxicity concerns.
- The study also reveals a troubling pattern known as “regrettable substitution,” where banned harmful substances are replaced by similar chemicals that cause comparable harm.
- The findings contrast with trends in human blood samples, where total organofluorine levels have remained stable or even increased despite declining concentrations of legacy PFAS, suggesting newer replacement PFAS may be accumulating primarily on land.

Division’s final journey
- Division, a four-year-old North Atlantic right whale known as Catalog #5217, was found dead off the coast of North Carolina in January after weeks in failing health caused by a severe fishing-gear entanglement that responders were unable to fully remove.
- Born in 2021 to a female named Silt, Division had already survived three earlier entanglements, a reminder of how early and repeatedly right whales now encounter life-threatening human hazards.
- His death comes amid fragile signs of hope for the species, with fifteen calves recorded this winter in a population of roughly 380 whales, far short of the numbers needed for recovery.
- Division’s short life illustrates how the threats facing right whales are not abstract but cumulative and prolonged, shaping lifespans measured in decades and placing the species’ future in the balance of decisions made far from the water.

Coast-to-coast coral assessment reveals Thailand’s reefs losing complexity
- Marine scientists have documented Thailand’s coral reefs in unprecedented detail, providing a crucial baseline against which reef managers can measure future change.
- The surveys indicate that, as in other parts of the world, Thailand’s reefs are losing structural complexity, becoming dominated by simpler boulder-forming corals, while staghorn and branching species die out.
- Experts say the new baseline can help steer future strategies to prepare for future bleaching events through reef restoration and assisted reproduction.
- The surveys were conducted just before the full effects of the 2024 global bleaching event were felt in Thai waters, which will have inevitably taken an as-yet-unquantified toll on the region’s reefs.

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

A new treaty comes into force to govern life on the high seas
- A new United Nations treaty governing biodiversity in areas beyond national jurisdiction will enter into force on January 17th 2026, creating the first global framework to conserve life on the high seas.
- The agreement covers roughly 60% of the ocean and introduces mechanisms for marine protected areas, environmental impact assessments, benefit-sharing from marine genetic resources, and capacity building for poorer states.
- Long treated as a global commons with weak oversight, international waters have seen mounting pressure from overfishing, prospective seabed mining, and bioprospecting, with less than 1.5% currently protected.
- The treaty’s significance will depend less on its text than on whether governments use it to impose real limits on exploitation and translate shared commitments into enforceable action.

Ocean set ‘alarming’ new temperature record in 2025
- Ocean temperatures set a record high in 2025, according to a new study.
- The authors found that the heat content of the ocean increased by about 23 zettajoules between 2024 and 2025. That’s roughly the equivalent of 210 times humanity’s annual electricity generation.
- The ocean has warmed significantly in recent decades largely because it absorbs roughly 90% of the excess heat trapped in the atmosphere by human-caused greenhouse gases. That makes the ocean a key indicator of global warming.
- Warming ocean temperatures contribute to sea-level rise and to extreme weather events, which were frequent in 2025.

Study tracks fishing boats to see how heat waves affect fish distribution
- A new study suggests an early way to detect ecological shifts during marine heat waves: Use fishing vessel tracking data.
- The study found that tracking data could provide early detection of extreme northward and inshore shifts in albacore tuna and Pacific bluefin tuna distribution in response to heat waves and showed when such shifts weren’t happening despite high sea surface temperatures.
- The authors position fishers as “apex predators” and build on research that finds that predators are good ecosystem sentinels.

South Africa’s great white shark population worries researchers
Great white shark populations in South Africa are disappearing, driven largely by human activities that are likely responsible for the collapse of a locally critical apex predator. That’s the conclusion of a review paper published by a group of scientists and conservationists who analyzed data on the abundance of great whites in South African waters. […]
Marine protected areas expanded in 2025, but still far from 30% goal
In December 2022, nearly 200 nations committed to protecting 30% of Earth’s lands and waters by 2030. As of 2025, about 9.6% of the world’s oceans are now covered by marine protected areas, according to the latest global tracking data by the World Database on Protected Areas. This marks a 1.2% increase in 2025, up […]
Azores must respect its exceptional network of marine protected areas (commentary)
- Just over a year ago, the Azores created the largest network of marine protected areas (MPAs) in the North Atlantic, becoming a beacon of hope and a global leader in ocean conservation.
- Then, in early 2025, a proposal to allow tuna fishing in “no-take” areas there was submitted to the Regional Assembly; this is currently under discussion and could come to a vote this week or next week.
- “Such a retreat from ocean protection would not only be a local tragedy but also a disheartening contribution to the global backpedaling on environmental political will,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Emma Johnston, a marine ecologist with institutional reach, has died at 52
- Emma Johnston, who died at 52 in December 2025, moved between marine science and university leadership, arguing that evidence matters only if it can be understood and acted upon beyond the laboratory.
- Trained as a marine ecologist, she built influential research programs on human impacts in coastal ecosystems and became a prominent public advocate for science in an era of misinformation and political noise.
- Her career expanded into national leadership roles, including president of Science & Technology Australia and senior research posts at UNSW and the University of Sydney, before she became vice-chancellor of the University of Melbourne in 2025.
- Though her tenure as vice-chancellor was brief, she pressed a strategy centered on resilience and education, leaving Australian science without a leader who could connect data, institutions, and public life with unusual clarity.

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.

Kristina Gjerde, defender of the deep ocean, has died
- Much of the global ocean lies beyond national borders, where governance long lagged behind industrial expansion and responsibility thinned with distance from shore.
- Kristina Maria Gjerde helped reframe that problem as one of law and institutions, combining science, legal craft, and persistence to make protection of the high seas politically workable.
- Over two decades, she built and sustained coalitions that turned scattered warnings about deep-sea damage into a binding international framework.
- That effort culminated in the 2023 High Seas Treaty, an agreement whose force lies less in sudden ambition than in the accumulation of careful, patient work.

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.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

Huge ‘blue carbon’ offsetting project takes root in the mangroves of Sierra Leone
- In October, a wholly owned subsidiary of West Africa Blue, a Mauritius-based company, signed a “blue carbon” offsetting deal with the 124 communities on the island of Sherbro in Sierre Leone.
- The agreement will reward the communities financially for conserving and restoring their mangroves, which act as a carbon sink.
- The funds will be generated by selling offsets on the voluntary carbon credit market, with revenues shared between West Africa Blue, the communities and the government of Sierra Leone.
- Though carbon offsetting projects have been subject to criticism in the past, community members on Sherbro say they’re optimistic about the improvements to their livelihoods that the project could bring.

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.

Century-old corals reveal the Pacific Northwest is acidifying faster than expected
- When compared with historical samples, corals show that the Salish Sea and California Current System are acidifying faster than anticipated because of greenhouse gas emissions. Models indicate that at this rate, carbon dioxide levels in the oceans will continue rising faster than concentrations in the atmosphere.
- Increasingly acidic seas pose growing risks to sensitive marine life, from clams and oysters to any organism with a spine, as well as economically important fisheries and the communities that depend on them.
- British marine ecologist Stephen Widdicombe calls the threat existential. Our continued failure to cut emissions can only lead to “a world where uncontrolled climate change including ocean acidification leaves us with an ocean that is less productive, less diverse and less able to provide humans with the wealth of services that we currently all benefit from,” he said.

Zombie urchins & the Blob: California sea otters face new threats & ecosystem shifts
- Southern sea otters living along California’s coast are struggling in warmer seas, with new threats and changing food sources. They, like the other two sea otter subspecies, are classified as endangered.
- Human disturbance, especially in Monterey Bay, is limiting the otters’ ability to forage, impacting mother and pup survival. Meanwhile, sharks are expanding their range as waters warm, with increasing attacks on otters.
- Following a mass die-off of the purple sea urchin’s predators — sunflower and ochre sea stars — the urchins decimated kelp forests, which are important sea otter habitat. Mussels then proliferated, replacing urchins in the otter’s diet, and invasive green crabs are now also on the menu.
- Otter numbers seem to be dropping, but a definitive census has not been conducted since 2019. A new population estimate based on data and statistical modeling is due to be released soon.

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.

Philippines’ newest marine protected area ‘sets inspiring example’ (commentary)
- Nestled in the heart of the Coral Triangle, one of the most biodiverse marine regions on the planet, Panaon Island is a jewel of the Philippines’ natural heritage.
- Despite its biodiversity, Panaon Island faces growing threats, so a broad coalition of community leaders, environmental advocates and government agencies have rallied to designate the waters surrounding it as a new marine protected area (MPA).
- But safeguarding marine habitats requires more than designations and new maps. “Marine protected areas need proper funding, active monitoring and strong enforcement to prevent illegal activities from undermining conservation,” a new op-ed says.
- This article is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Seafloor survey in Cambodia finds simple anti-trawling blocks help seagrass recover
- A recent study provides the first large-scale map of Cambodia’s coastal habitats and reports early seagrass recovery near anti-trawling structures in the Kep Marine Fisheries Management Area.
- Surveys across 62,146 hectares (153,566 acres) show a 39% loss of seagrass cover in Kampot province over the past decade.
- The study doesn’t examine potential impacts from the planned $1.7 billion Funan Techo Canal, which is set to meet the sea about 2.5 kilometers (1.6 miles) away from the Kep Marine Fisheries Management Area.

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

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

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

Unregulated tourism risks disrupting Timor-Leste’s whale migration
- 2025 has been a big whale tourism season in Timor-Leste; operators were fully booked during the peak season of September to December.
- But increasingly aggressive practices fueled by competition between tour operators could mean “another Sri Lanka,” where whales already stressed by climate-induced food scarcity are disappearing from the area.
- East Timorese are mostly excluded from the sector, which is controlled by expats and foreign tour operators raking in thousands from “bucket listers” and social media “influencers.”
- Whale tourism in Timor-Leste needs regulation, enforcement and legal compliance to ensure sustainable, inclusive growth, experts say.

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.

The last of the Vaquita Porpoise (cartoon)
With an estimated less than 10 individuals alive, the vaquita porpoise of the Gulf of California is on the brink of extinction. Entanglement in gill nets used for fishing totoaba fish in the Sea of Cortez has been the prime threat to vaquitas, and while bans are already in place, the lack of enforcement leaves […]
Philippine mangroves survived a typhoon, but now confront a human-made challenge
- A new study shows mangroves in Tacloban, the Philippine city hit hardest hit by Typhoon Haiyan in December 2013, have expanded beyond pre-storm levels.
- This recovery was driven by community-led reforestation efforts from 2015-2018, when residents planted 30,000 Rhizophora mangrove seedlings across 4 hectares (10 acres) of Cancabato Bay.
- Satellite image analysis and modeling reveal how the forest was destroyed by Haiyan and how it later withstood 2019’s Typhoon Phanfone.
- However, experts warn that the recovering mangroves may be threatened by an ongoing project to build a causeway across the bay, which could generate pollution and physical disturbances.

Countries back strong new trade limits for sharks and rays at CITES summit
Delegates at a global summit to update international wildlife trade rules have agreed on sweeping new protections for more than 70 shark and ray species. The move marks a significant step toward effectively tightening the legal trade in some of the world’s most threatened marine life. The meeting in Samarkand, Uzbekistan, running through this week, […]
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.

What’s at stake for the environment in Honduras’ presidential election?
- Honduras will hold elections Nov. 30 for president and all 128 seats in Congress.
- The winners will hold office for the next four years, shaping the country’s environmental policies at a time when its many forests and ocean ecosystems are rapidly disappearing.
- Leading candidates include Rixi Moncada of the progressive LIBRE party, Salvador Nasralla of the centrist Liberal party and Nasry ‘Tito’ Asfura of the conservative National party.

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.

COP30: What did it deliver for the ocean?
- As climate change talks took center stage at COP30, a growing number of countries have integrated ocean-based solutions into their national climate commitments.
- A new report found that 92% of coastal and island nations’ updated climate plans now include ocean-related measures, although these strategies still represent only 12% of all proposed climate mitigation actions.
- Brazil and France unveiled a Blue NDC Implementation Taskforce to boost ocean solutions, while countries like the Solomon Islands and Ghana launched new plans for protecting their marine and coastal systems.

Abrolhos: A South Atlantic marine treasure in need of protection
- Located off the coast of the Brazilian states of Bahia and Espírito Santo, the vast Abrolhos Seascape is home to some of the South Atlantic Ocean’s richest marine biodiversity. Here, more than 500 species inhabit coral reefs, mangrove forests and islands. Brazil’s largest humpback whale breeding ground also occurs within the seascape.
- Yet little legislation has been created to protect this region, leaving it at risk of predatory fishing and deep-sea mining: Less than 2% of the South Atlantic’s largest coral reef, which occupies 46,000 square kilometers within the wider Abrolhos Seascape, is fully protected.
- A recent study identified critical areas and vulnerable ecosystems within Abrolhos Seascape that the authors say need urgent conservation action; these include rhodolith beds — clusters of limestone rock that are crucial for climate security and marine species reproduction.

‘Forever chemical’ contamination could undermine sea otters’ fragile recovery in Canada
- Sea otters living along the coastline of Canada’s British Columbia province are exposed — and absorb — forever chemicals, a new study shows.
- Each of the 11 sea otters tested carried residues PFAS chemicals, with concentrations higher for those living near dense human populations or shipping lanes.
- The Canadian government released an assessment earlier this year recommending that PFAS be classed as toxic and is moving toward adopting tighter rules for these chemicals. Environmentalists support the initiative.

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

Lethal dose of plastic for seabirds and marine animals ‘much smaller than expected’
- A new study looking at the impacts of plastic ingestion by seabirds, sea turtles and marine mammals found that relatively small amounts of consumed plastic can be deadly.
- The research analyzed the necropsy results for more than 10,000 animals and quantified the amount of plastic that could prove deadly as well as the types of plastic with the biggest impact, which included synthetic rubber, soft plastics (such as plastic bags and wrappers) and discarded plastic fishing gear.
- Overall, one in five of the deceased animals had consumed plastic (affecting 50% of all studied sea turtles, 35% of seabirds and 12% of marine mammals); nearly half of the species studied were considered threatened or near threatened on the IUCN Red List.
- The researchers didn’t consider other health impacts of plastic, such as chemical exposure and entanglement, which led the lead author to conclude the study likely underestimates the “existential threat that plastic pollution poses to ocean wildlife.”

Offshore fossil fuel exploration jeopardizes Brazil’s climate leadership, study says
- Ahead of the COP30 U.N. climate summit in Brazil, a report by environment-monitoring organization SkyTruth mapped the environmental impact of the advance of offshore exploration for fossil fuels in Brazil, criticizing the country’s unfulfilled energy transition promises.
- The study detected 179 probable oil slicks in Brazilian waters since 2017, as the oil and gas sectors boomed. Analyses showed that traffic from fossil-industry vessels grew by 81% between 2012 and 2023, while methane burning skyrocketed — releasing into the atmosphere the equivalent emissions of 6.9 million cars annually.
- According to the investigation, Brazil still embraces environmentally controversial initiatives, such as oil exploration at the mouth of the Amazon River. This agenda brings risks to rich marine ecosystems and Indigenous and traditional communities, moving the country further away from its climate and conservation goals.

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.

Construction of TotalEnergies pipeline cuts through coral reefs in Mozambique
- A Dutch company dredged through a highly sensitive coral area for TotalEnergies’ liquefied natural gas project in Mozambique, satellite imagery and vessel traffic data confirm.
- The French oil and gas company declared force majeure after insurgents attacked the facility in 2021, but some work on the project continued.
- Environmental groups warn that the environmental impact assessments for TotalEnergies’ project and three others in the same waters are inadequate.

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.

Plans to dispose of mining waste in Norway’s Arctic Ocean worries Sámi fishers, herders
- Mining company Blue Moon Metals plans to dispose of its mining waste in Repparfjord, a nationally protected salmon fjord in the Norwegian Arctic that Indigenous Sámi fishers rely on.
- When operational, the Nussir ASA copper mine will deposit between 1 million and 2 million metric tons of tailings at the bottom of the fjord annually, according to the company’s permit.
- The Norwegian Environment Agency told Mongabay that the company plans to place its mining waste into the fjord in a controlled manner to limit the dispersal of harmful residues.
- Some Sámi residents, whose livelihoods depend on fishing and reindeer herding, told Mongabay they fear the tailings and mine will destroy vital marine habitats for salmon and disrupt traditional reindeer breeding and migration areas.

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.

A 2021 debt-for-nature “blue bond” […]
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.
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Expedition charts Cook Islands seafloor, amid scrutiny over mining motives
- Between Oct. 1 and 21, a U.S government-funded vessel, the E/V Nautilus, conducted an expedition in the Cook Islands’ exclusive economic zone (EEZ), following an agreement between the U.S. and the Cook Islands to “advance scientific research and the responsible development of seabed mineral resources.”
- During the 21-day expedition, the E/V Nautilus mapped more than 14,000 square kilometers (5,400 square miles) of the Cook Islands’ seafloor while also documenting deep-sea biodiversity.
- Environmental activists protested the expedition, arguing it would help accelerate deep-sea mining in the Cook Islands. The crew of the E/V Nautilus, however, rejects the accusation.
- The Cook Islands government has issued three deep-sea mining exploration licenses, which will expire in 2027. One company operating in the Cook Islands has said it hopes to apply for an exploitation license in 2027.

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.

Ethanol plant spills harmful wastewater into Philippine marine reserve
A chemical spill from an ethanol distillery has put one of the Philippines’ largest marine protected areas at risk. A wall retaining the wastewater pond of an ethanol distillery plant collapsed on Oct. 24, causing about 255,000 cubic meters (67 million gallons) of wastewater to flow into Bais Bay in the central Philippines, according to […]
Antarctic conservation summit closes with stalemate on MPAs & krill fishing rules
- The annual meeting of the international body responsible for the conservation of Southern Ocean marine ecosystems concluded Friday with no progress on two contentious issues before it: the creation of new marine protected areas and the strengthening of regulations governing the fishery for krill (Euphausia superba), a species on which numerous iconic species of Antarctic wildlife depend.
- This year’s annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) was particularly tense, due to a clash between two occasionally overlapping groups of countries: on one side, those working to establish new marine protected areas (MPAs), and on the other, those more focused on increasing krill fishing.
- CCAMLR has considered proposals to establish three large MPAs annually for years but has failed to pass them under its consensus-based decision-making process. This year was the same, due to vetoes of MPA proposals by Russia and China.
- The combination of a lack of will to reinstate previously agreed regulations governing the krill fishery and a new push to drastically increase the krill harvest suggests a change in direction at CCAMLR toward more permissive fishing.

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.

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

On first International Day of the Deep Seabed, we seek stewardship and consensus (commentary)
- “I could not be more delighted to celebrate this inaugural International Day of the Deep Seabed,” writes the secretary-general of the International Seabed Authority (ISA) in a new op-ed at Mongabay.
- On Nov. 1, 2025, she notes that the world will for the first time mark a day that celebrates the great biodiversity of the planet’s mysterious deep seabed and its potential role in the future of humanity’s progress, while reiterating that consensus-building among member states and nongovernmental actors remains critical to ensure its stewardship.
- “Together, by delivering on our commitments under the Law of the Sea, we can ensure that this last great frontier remains a source of wonder, discovery, opportunity and shared benefit for all humankind,” she argues.

In Mauritius, an NGO is tracking the sex life of corals to save them
- Mauritius will soon be home to one of the largest projects in the Western Indian Ocean aimed at restoring corals through sexual propagation.
- The scientific research for the Odysseo coral restoration initiative is led by U.S.-based nonprofit Secore, which has also worked in the Caribbean Sea and reported success in breeding heat-tolerant corals.
- The initiative aligns with a recent policy push by the Mauritian government to promote coral restoration through sexual propagation as opposed to through asexual methods.
- However, this method of coral restoration is in its nascency in this region, and Secore is currently focused on gathering knowledge that will help it choose species to breed, donor sites to collect sperm and egg cells, and transplanting sites for newly grown coral.

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.

Australia celebrates ‘humpback comeback,’ but a main food source is under threat
News of Australia’s “humpback comeback” is making waves globally. Numbers of humpback whales (Megaptera novaeangliae) on the nation’s east coast have rebounded to an estimated 50,000 from a historic low of just a few hundred before commercial whaling was outlawed in the 1970s. And wildlife scientist and whale expert Vanessa Pirotta joins the podcast to […]
‘A very successful story’: An Egypt tribe welcomes tourists & protects its coast
- Al-Qula’an is an “eco-village” in the Wadi El Gemal protected area in Egypt that environmentalists say is an example of how eco-tourism, along with traditional knowledge and practices, can help protect sensitive ecosystems.
- The mangroves of Al-Qula’an provide nursery grounds for marine species, and the coastal habitats serve as nesting sites for endangered sea turtles.
- The village has transformed from a subsistence fishing community to a low-impact eco-tourism destination while upholding principles of the Ababda tribe, like the importance of preserving mangroves.

Arctic seals edge closer to extinction as sea ice vanishes
- Three Arctic seal species have been moved up to higher threat categories on the IUCN Red List, with one now endangered and two now near threatened.
- Global warming is melting away the sea ice they need for breeding, resting and feeding, which has led to widespread breeding failures among ice-dependent seals.
- Loss of sea ice is also opening the region to more human activity, including shipping and oil exploration, bringing added disturbance, noise and pollution.
- The IUCN warns a similar pattern is emerging in the Antarctic. It says urgent global emissions cuts, along with stronger local protections such as reducing bycatch and pollution, are needed to prevent further declines.

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.

Booming sea otters and fading shellfish spark values clash in Alaska
- In Alaska, a state brimming with iconic wildlife — from grizzly bears to king salmon, humpback whales to harbor seals — the charismatic, densely coated sea otter stands out as perhaps the state’s most hotly debated, controversial species.
- Sea otters were nearly hunted into extinction a century ago for their luxurious pelts. But they have been surging in population in the Gulf of Alaska, bringing both benefits to nearshore ecosystems and drawbacks to the shellfish economy (due to the otters’ voracious caloric needs).
- Described by commercial shellfish harvesters and Native Alaskans as pillagers of clams and crabs, sea otters are seen by many marine biologists as having positive impacts on kelp forests — important for biodiversity and carbon storage. Scientists stress that shellfish declines are complex, with sea otters being just one among multiple causes.
- Native Alaskans are the only people given free rein to hunt sea otters. But long-standing federal regulations stipulating who qualifies as Native Alaskan make it illegal for most to manage their own waters. Tribes are fighting for regulatory changes that would enable them to hunt and help balance booming sea otter populations.

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

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

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.

State-NGO collaboration expands protection for Patagonia’s biodiversity hotspot
- A new provincial park in the province of Chubut aims to conserve one of Argentina’s most biodiverse stretches of coastline.
- The park is based on a conservation model that involves an NGO buying up private land and then donating it back to the provincial government in return for new legal protections.
- The park will complement existing legislation and the area’s existing status as a UNESCO Biosphere Reserve.
- Sustainable, low-impact tourism and a no-take fishing zone, which will support the local shrimp industry, are both set to give the region an economic boost.

Nickel mining threatens Raja Ampat ecosystems, communities & conservation: Report
- A new environmental report warns that expanding nickel mining is placing Raja Ampat’s coral reefs, forests and Indigenous communities under intensifying threat.
- Using geospatial mapping and field evidence, researchers document how mining concessions overlap with critical ecosystems and biodiversity hotspots within the UNESCO-designated geopark.
- They also describe the industry’s deep colonial-era roots, its modern expansion under state and private control and its connections to global electric vehicle supply chains through companies like Tesla, Ford and Volkswagen.
- Activists are urging the Indonesian government to revoke all remaining mining permits, enforce no-go zones and shift toward sustainable economic alternatives that protect the archipelago’s ecological and cultural heritage.

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 […]
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.

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

What fuel will ships burn as they move toward net zero?
- Spurred largely by pending global regulations, the race is on to develop low- and zero-carbon fuels for ships and scale up their use.
- There are “bridge fuels” that could be used during a transition period or in a limited way for the long term, such as biofuels, and then there are options that are more sustainable at scale, such as green methanol and green ammonia.
- Experts continue to debate the pros and cons of green methanol and green ammonia, which are generally seen as the best options in the medium to long term.
- A net-zero framework for shipping that would drive the adoption of alternative fuels is coming up for a vote in mid-October at a meeting of the International Maritime Organization in London.

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

Just as Raja Ampat fetches UNESCO Biosphere Reserve title, nickel mining looms
- On Sept. 27, UNESCO designated 26 new biosphere reserves, including Indonesia’s Raja Ampat, which is also recognized as a UNESCO Global Geopark; the two designations make it one of few places on Earth honored for both geological heritage and biodiversity.
- Yet nickel mining threatens to carve up the region’s forests and coral reefs; a new report finds that nickel concessions in Raja Ampat cover 22,000 hectares, including zones that overlap with coral reefs and marine habitats.
- This raises questions about whether international recognition alone can safeguard Raja Ampat against the growing pressure of nickel extraction, driven by global demand for batteries in electric vehicles and renewable energy storage.

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.

Northeast Pacific endures fourth-largest marine heat wave on record
The Northeast Pacific ocean, off the U.S. West Coast, is experiencing its fourth-largest marine heat wave since record-keeping began in 1982. “The extent of the current Pacific marine heatwave should be surprising … but unfortunately, record breaking heat is our new norm,” Chris Free, a marine scientist at the University of California, Santa Barbara, told […]
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.

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

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

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

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 […]
Scientists develop sunscreen made from pollen that doesn’t harm corals
Scientists have invented a pollen-based sunscreen, which their results suggest is as effective in blocking harmful ultraviolet rays as sunscreens containing chemicals that contribute to coral bleaching and pollution in oceans. In a recently published study, the researchers also showed their pollen sunscreen doesn’t harm corals. They added 1 milliliter (0.034 ounces) of both their […]
Iberian orcas sink sailboat in latest ramming ‘game’ in Portugal
Five people were rescued after a pod of critically endangered Iberian orcas rammed into a sailboat several times, causing it to sink off Portugal’s Costa do Caparica, near the nation’s capital, Lisbon, on Sept. 13. None of the people on board suffered any injuries, according to the Portuguese maritime authority. The boat, owned by yacht […]
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.

Most Caribbean coral reefs to stop growing by 2040, study warns
Most coral reefs in the Caribbean could stop growing, and even start eroding away, by 2040 if global warming continues unchecked, a new study finds. Coral reefs, especially those near shores, protect valuable coastlines from flooding during cyclones and storm surges by breaking up wave energy. For the reefs to continue to act as natural […]
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.

With global rules pending, can the shipping industry get more carbon efficient?
- The European Union and the International Maritime Organization have advanced shipping decarbonization regulations that will raise the price of maritime fuels.
- The push could lead to increased use of efficiency measures that reduce how much fuel vessels need in the first place.
- Such measures include everything from adding sails to ships to lubricating or redesigning hulls and optimizing routes or arrival times. These are cheaper and more immediately available than alternative fuels.
- Many associations and companies, particularly in Europe, are working to make efficiency gains as fast as possible.

Indonesia reopens Raja Ampat nickel mine despite reef damage concerns
- Indonesia has allowed state-owned PT Gag Nikel to resume mining operations on Gag Island in Raja Ampat, despite a ban on mining small islands and a previous suspension imposed in June.
- A 2024 survey commissioned by Gag Nikel reported widespread community complaints of dust, health issues, sedimentation, and coral damage from barges — contradicting the government’s claims of minimal impact.
- NGOs say the “green” rating cited by the government to justify the resumption masks real destruction in Raja Ampat, one of the world’s richest marine ecosystems, and note the government has revoked other mining concessions in the area for similar impacts but not Gag Nikel’s.
- More than 60,000 people have signed a Greenpeace petition opposing mining in Raja Ampat, warning sedimentation could destroy coral reefs and threaten local livelihoods even as the nickel feeds Indonesia’s EV battery supply chain.

On World Dolphin Day, spotlight falls on threats to dolphins worldwide
September 12 is World Dolphin Day. Marine conservation and advocacy nonprofit Sea Shepherd created the day in 2022 to remember that dolphins, among the most intelligent animals on Earth, are under threat and need protection. That date, Sept. 12, was chosen to memorialize the massacre of 1,428 Atlantic white-sided dolphins (Leucopleurus acutus) on the Faroe […]
Experimental ocean climate fixes move ahead without regulation
Experimental climate interventions in the world’s oceans are moving ahead in a regulatory vacuum, raising concerns among scientists about potential risks, Mongabay staff writer Edward Carver reported. The projects, known as marine-climate interventions, aim to tackle global warming or help people and ocean life adapt to climate change. But a group of 24 researchers warned […]
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 […]
Top court delivers a ‘huge’ climate win for island nations
The recent advisory opinion from the International Court of Justice (ICJ) on states’ obligations regarding climate change was celebrated globally for providing clarity on countries’ legal obligation to prevent climate harm, but was also appreciated by island nations for its additional certainty on their maritime boundaries remaining intact regardless of sea level rise. This week […]
Post-Blob, California’s kelp crisis isn’t going away
- Kelp forests function as major habitat for marine biodiversity, but are in rapid decline worldwide, largely because of climate impacts on the oceans.
- A 2013 marine heat wave known as “the Blob,” combined with the mass die-off of sea stars, caused a 95% loss of Northern California’s kelp forests.
- The loss of sea stars allowed the purple urchins that they thrive on to spread rapidly, converting lush kelp forests into “urchin barrens” in parts of California. There’s been very little recovery since.
- Restoration of kelp forests is extremely difficult and requires far more resources than are currently being committed.

Philippines protects huge coral hotspot off the coast of Panaon Island
The corals around Panaon Island in the southeastern Philippines form some of the healthiest and most climate-resilient reefs in the world, and they’re now a legally protected seascape. Philippine President Ferdinand Marcos Jr. approved the Panaon Island Protected Seascape law on Aug. 29. It creates a 61,204-hectare (151,200-acre) marine protected area within the Pacific Coral […]
Cruise industry expansion collides with Cozumel’s coral reef
- Mexico’s Cozumel Island is one of the most popular cruise ship destinations in the world, hosting more than 4.5 million tourists every year.
- A plan to build a new pier for cruise ships has attracted concern from Cozumel residents and conservationists, who say it will damage the surrounding reef and block public access to the sea.
- The company behind the project, Muelles del Caribe, maintains the pier will bring financial benefits to the community.
- Conservationists assert that the project’s environmental impact assessment was insufficient; in July, a court ordered a temporary suspension of the project to allow for a more thorough environmental assessment.

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.”

Sunscreens protect us but also pose real planetary health concerns
- Sunscreens have become an important part of people’s sun management routine, protecting skin from harmful solar UV radiation. But many of these products contain chemicals that can be harmful to saltwater and freshwater ecosystems, while preliminary findings indicate some ingredients can have health effects.
- Ultraviolet filter chemicals and mineral components found in sunscreens can harm marine species such as corals and help trigger bleaching. In recent years, numerous studies have shown that many of these chemicals persist in the environment and can impact seagrass, fish and other marine life.
- More research is needed to understand the full environmental and health impacts of chemicals used in sunscreens. New formulations using ingredients proven to be safe are required, say analysts, and makers should improve product labelling to better inform consumers, with government regulation potentially necessary.
- Experts also urge caution, noting that while there are environmental concerns surrounding sunscreen chemicals, this should not be understood as a call not to use these products.

Why the BBNJ treaty on marine biodiversity matters more in the Mediterranean (commentary)
- The Mediterranean Sea covers less than 1% of the world’s ocean surface, yet hosts more than 18% of its known marine species, while being beset by unresolved maritime boundaries plus growing pressure from climate change, overfishing and pollution.
- That’s why this marine ecology hotspot needs the new U.N. treaty on oceanic biodiversity (BBNJ), as it offers a unique chance for Mediterranean countries to cooperate on common ground: despite claims that it lies outside of the scope of the agreement, there are legal grounds to claim the contrary.
- “Vast areas of the Mediterranean remain undelimited and unclaimed, existing in a legal gray zone. Under international law, these areas are considered de facto beyond national jurisdiction and therefore within the geographical scope of the BBNJ Agreement,” the authors of a new op-ed argue. “By mobilizing diplomatic, legal and financial resources through its institutions and member states, the EU can help catalyze broader regional ratification and implementation.”

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

Indonesia’s Bajau fishers lament nickel mining’s marine pollution
For many members of the nomadic Bajau sea tribe on Indonesia’s Kabaena Island, growing up meant swimming and fishing in clear waters, just outside their homes built on stilts. However, in 2010, the water turned red, which the villagers blame on runoff from nearby nickel mining, Mongabay’s Hans Nicholas Jong reported in July. “Now, I […]
Brazil cities order endangered angelshark meat despite fishing ban
Government agencies in Brazil’s Rio Grande do Sul state launched public procurements for more than 200 metric tons of meat from endangered angelshark species between 2015 and 2025, a Mongabay investigation has revealed. The meat is served in public institutions, including schools. Fishing for angelsharks is prohibited in Brazil, but its trade is legal if […]
Philippine fishers struggle as LNG ‘superhighway’ cuts through biodiversity hotspot
Fishers in the Philippines’ Batangas Bay are struggling to make ends meet and feed their families as nearby coastal areas are developed into a natural gas import hub, Mongabay contributor Nick Aspinwall reported in July. Families that have been fishing in Batangas Bay for years have been asked by local officials to leave to make […]
Community efforts yield new marine protected area in the Philippines
The Philippines has officially designated a new marine protected area after an 18-year campaign by local communities, fisher associations, civil society organizations and government agencies, the Wildlife Conservation Society announced Aug. 13. The newly created Bitaug Marine Protected Area (MPA), which covers nearly 150 hectares (about 370 acres), is the largest MPA in Siquijor province […]
Indonesia’s aquafarm revamp sparks fears for fate of farmers and mangroves
- Indonesia plans to revitalize 78,000 hectares (193,000 acres) of state-owned aquaculture ponds, starting with 20,400 hectares (50,400 acres) in West Java province, aiming to boost yields, create 119,000 jobs and attract investors.
- Small-scale farmers like Warno in Karawang district, who rent and maintain ponds from the state, say they fear losing their livelihoods without compensation if the government takes over their farms.
- NGOs and experts warn the program could fuel mangrove clearing, coastal damage and privatization of coastal areas, while sidelining local communities’ rights and voices.
- Critics also raise concerns over the government’s push for more farming of saltwater tilapia, citing risks from the invasive species and an industrial aquaculture model that could reduce locals to laborers.

Belize project seeks out heat-resilient corals to protect its reefs
- An initiative called the Super Reefs program is setting out to identify the corals in Belize’s waters that have the highest chance of surviving warming waters amid climate change.
- Researchers with the program have discovered that corals that grow in the hottest areas are naturally more heat-resistant.
- Massive starlet coral (Siderastrea siderea) tends to be tolerant of warm water, whereas symmetrical brain coral (Pseudodiploria strigosa) is more sensitive.
- The team plans to use its findings, which are to be published by 2026, to inform the Belize government which coral communities in the country are best suited for protection and restoration.

Deep-sea mining is a false solution to our challenges (commentary)
- A new op-ed argues that the case for deep-sea mining is weak and also that the facts used by its proponents don’t add up, but rather cloud their judgment.
- The divergence between scientific understanding of likely ecological harms and prevailing narratives — like the touted economic benefits, which could actually be costs — came into sharp focus at the recent annual meeting of the International Seabed Authority, which governs the development of this industry.
- “Given the high costs and severe environmental risks, why then pursue deep-sea mining? This activity threatens unique deep-sea ecosystems and could irrevocably alter ocean health, impacting life on land,” the author writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Whale shark hotspot discovered along the Great Barrier Reef
- Whale sharks (Rhincodon typus) are the largest fish in the world and are endangered but are hard to study because they’re largely solitary creatures that roam great distances.
- There are only about 30 sites worldwide where they’re known to aggregate — and scientists have finally identified one of them along the Great Barrier Reef, a new study reveals.
- It’s the first known aggregation found in eastern Australia and in the entire southwest Pacific Ocean.
- The finding is significant for whale shark research and conservation efforts, experts said.

Ocean-based carbon storage ramps up, bringing investment and concern
- Storing captured carbon in the subsea — in depleted oil and gas wells or in aquifers — is ramping up as a climate solution, with projects planned across the globe by industry and governments.
- Tipped as a way to address “hard-to-abate” emissions from industries such as cement, steelmaking and chemicals, it’s hailed by proponents as a viable and necessary part of the transition to net-zero greenhouse gas emissions.
- But critics say offshore CCS poses great risks and will perpetuate a history of failure that has plagued onshore efforts to store carbon.
- It also raises environmental concerns, such as the potential for carbon leakage that could undermine climate efforts and harm marine life, contributing to already increasing ocean acidification.

There’s hope for sunflower sea stars, with their killer unmasked and reintroductions pending
- Since 2013, sea star wasting disease, worsened by warming oceans, has wiped out 99% of sunflower sea stars from Washington state to Mexico, collapsing kelp forest ecosystems.
- Researchers from the University of British Columbia and the Hakai Institute in Canada have pinpointed the bacterium Vibrio pectenicida as a key cause of the epidemic, confirming its lethal effects through lab experiments that replicated symptoms seen in the wild.
- A coalition of aquariums, nonprofits, Indigenous groups and government agencies has successfully bred sunflower sea stars in captivity for the first time, experimenting with fresh, frozen and cryopreserved sperm, and raising 72 juveniles in a Monterey facility with plans for controlled releases.
- Guided by the Pycnopodia Recovery Working Group and a 2024-2027 conservation plan, efforts have now turned to breeding, disease research, habitat protection, regulatory engagement and public outreach, with broad community support — including from fishers — for restoring this keystone predator.

Argentina pushes pipeline exports through protected Patagonian waters
- In Argentina, the construction of an oil port and a liquefied natural gas (LNG) terminal for ships threatens one of the most biodiverse areas in the southwestern Atlantic.
- The law that protected the area from these types of projects was amended without prior consultation in 2022.
- Oil spills, rising water temperatures, and ship strikes on the thriving whale population are among the greatest threats highlighted by critics.

Microbiomes may be corals’ secret weapon against climate change: Study
- Researchers compared how genetically similar populations of Pocillopora corals cope with heat stress in Panama’s Gulf of Panama and Gulf of Chiriquí, both on the Pacific coast.
- The team looked at the entire holobiont — the coral’s symbionts, microbiome and physiology — in addition to its genome and environment, finding that the holobiont may play an outsized role in boosting the corals’ ability to cope with heat extremes.
- The team found that corals exposed to upwelling in the Gulf of Panama were better able to withstand higher temperatures, thanks in part to their microbiomes.
- The work points to the importance of better understanding how symbiotic relationships and microbiomes interact with corals to increase their resilience.

Goldman Prize winner’s shift from engineer to activist in Tenerife, Canary Islands
Carlos Mallo Molina grew up inspired by his engineer father who led port construction projects across Spain. But while working on a highway project in Tenerife, one of Spain’s Canary Islands, Molina realized that a related plan to build a port in a marine protected area threatened the marine ecosystem that he had come to […]
Can we undo extinction? A growing effort to restore lost sharks
- ReShark is the world’s first shark rewilding program, aiming to restore Indo-Pacific leopard sharks to reefs where they’ve disappeared, starting in Raja Ampat, Indonesia.
- The initiative repurposes surplus eggs from aquariums, transporting them across oceans and rearing them in locally managed hatcheries before releasing them into the wild.
- A growing community of Indonesian conservationists—including trained “shark nannies,” students, and villagers—is central to the project’s success and sustainability.
- With global collaboration and scientific rigor, ReShark aims to produce a model for reversing extinction—one grounded in genetics, local stewardship, and public engagement.

Scientists identify the bacterium behind billions of sea star deaths
More than a decade ago, a mysterious illness killed billions of sea stars, particularly along the North American Pacific coast. The sea star wasting disease caused the stars to develop lesions, their arms to fall off and their bodies to disintegrate. Now, researchers in a recent study say they have zeroed in on the cause: […]
Revealed: Brazilian state buys endangered angelsharks for school lunches
Endangered angelsharks have been served to schoolchildren in the Brazilian state of Rio Grande do Sul for years, as well as in hospitals, clinics, shelters and other public institutions, Mongabay has found. We identified 52 tenders totaling more than 211 metric tons of “peixe anjo,” a common name for angelshark, issued by the state and city […]
World’s first industry-wide climate mandate could be launched with shipping vote
- Shipping could become the first industry governed by a global treaty that sets enforceable decarbonization standards.
- In October, more than 100 nations will gather at a meeting of the International Maritime Organization (IMO) in London to potentially adopt a “net-zero framework” for the industry.
- In 2023, the IMO, a United Nations body that regulates shipping, developed a nonbinding strategy to decarbonize “by or around” 2050; the new framework would make that vision concrete and binding. Critics from small island developing states and environmental groups say the framework falls short of fulfilling the original vision.
- Some oil-exporting countries opposed the deal, arguing that alternative fuels are costly and unproven.

Encouraging signs from a no-fishing zone in Comoros could inspire others
- Signs of improvement in fisheries arising from a small no-fishing zone in the Indian Ocean nation of Comoros could inspire the establishment of more such zones across the archipelago.
- A fishers’ group installed the first no-take zone inside a marine protected area off the island of Anjouan in 2021. The group’s president told Mongabay fishers are now encountering more fish nearer to the shore outside the zone’s bounds.
- Buoyed by the results, a local nonprofit plans to establish five no-take zones in Anjouan over the next two years, covering 425 hectares (1,050 acres) of coral reefs.
- Earlier efforts to enforce temporary fishing closures to promote octopus fisheries for export and reduce pressure on fragile coral reef ecosystems didn’t lead to the anticipated benefits.

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

UN meeting closes with no moratorium on deep-sea mining; groups lament
Civil groups expressed dismay as the 30th International Seabed Authority (ISA) session recently ended in Jamaica without a moratorium on deep-sea mining, a process of extracting minerals from the seafloor, which experts say can damage marine ecosystems. The ISA Council finished the second reading of the draft regulations for the commercial exploitation of deep-sea minerals. However, the […]
Malaysia’s turtle egg buyback scheme saved thousands — but is it sustainable?
- A recent study assessed the effectiveness of Malaysia’s decades-old sea turtle egg buyback scheme, which aims to prevent eggs from entering the illegal wildlife trade by purchasing them from licensed collectors and relocating them to hatcheries.
- Between 2016 and 2021, more than 71,000 green turtle eggs were purchased and relocated, resulting in high hatching (77.6%) and emergence (74.1%) success rates — highlighting the scheme’s biological effectiveness despite covering only a small fraction of total nests.
- The study flagged significant financial and logistical challenges, including rising costs, seasonal erosion, inconsistent cooperation from collectors, and limited capacity to purchase all available eggs, prompting concerns about long-term sustainability.
- With a statewide ban on turtle egg trade now in place, researchers and experts question whether the buyback model should continue, suggesting alternative strategies like nonextractive income opportunities and stronger enforcement against illegal trade.

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

Sri Lanka Supreme Court orders $1 bn payment in X Press Pearl marine disaster
- Sri Lanka’s Supreme Court has ordered $1 billion in compensation from the owners and local agents of the MV X-Press Pearl, which sank off Colombo in 2021, causing the worst maritime disaster in the island’s history and a massive marine plastic spill.
- The court held both the vessel’s operators and two former Sri Lankan officials accountable, citing negligence and violations of citizens’ constitutional rights.
- The July 24 ruling calls for the establishment of an independent compensation commission and requires the first installment of damages to be paid by September 2025, with a review hearing scheduled for the same month.
- Environmentalists describe the judgment as a milestone in line with the “polluter pays” principle, offering a potential model for environmental justice across the Global South.

Coral restoration after devasting Deepwater Horizon spill shows promise
When BP’s Deepwater Horizon oil rig exploded in the Gulf of Mexico in 2011, it led to the largest oil spill in U.S. history, severely damaging marine ecosystems. Part of the settlement money that BP agreed to pay has since been used for a deep-sea restoration project that has achieved significant milestones in spawning corals […]
Reversing damage to the world’s mangrove forests
Mangroves are an important lifeline for biodiversity, climate and coastal communities. Yet they are disappearing 3-5 times faster than total global forest losses, according to UNESCO. On July 26, celebrated as the International Day for the Conservation of the Mangrove Ecosystem, we present recent stories by Mongabay’s journalists on emerging threats to these critical ecosystems […]
Sri Lanka hit by plastic pollution after cargo ship sinks off Indian coast
Sri Lankan authorities, locals and environmentalists say they’re deeply concerned about the possible impacts on the country’s marine ecosystem and coastal communities from the sinking of a container ship off the southern coast of India in May, Mongabay contributor Malaka Rodrigo reported in June. The Liberia-flagged ship MSC Elsa 3 sank on May 25 about […]
Saving polar bears and beluga whales: Interview with Alysa McCall
- Beluga Cam is a long-running initiative that aims to document the migration of almost 57,000 beluga whales through Hudson Bay in Canada.
- The project is run by the nonprofit Polar Bears International in a bid to collect more data about beluga migration as well as to create more awareness about the species.
- The initiative got an upgrade this year with a new boat that houses the cameras and other equipment deployed for the work.
- As the Arctic rapidly loses sea ice, species such as beluga whales and polar bears bear the brunt in terms of losing access to food and their habitats.

Blue carbon ecosystems are key for protecting the Philippines from climate shocks (commentary)
- In the wake of historic typhoon activity in 2024, members of the Zoological Society of London (ZSL) and others are calling for scaled-up coordination and action to safeguard blue carbon ecosystems that increase local capacity to recover from climactic shocks.
- Community-led projects that offer opportunities to increase investment and bring security back to local communities like mangrove forest restoration are one key example of a blue carbon initiative that the National Blue Carbon Action Partnership (NBCAP) is implementing with the support of ZSL.
- “Coordinated action by NBCAP will enable these ecosystems to come to life, delivering both protection and income for coastal communities,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Darkest-ever dwarfgoby fish gets named after Darth Vader
From the volcanic fjords of Tufi in Papua New Guinea, researchers have described a new-to-science species of a coral reef fish called a dwarfgoby with an unusual purplish-black color. The tiny fish is the “darkest of all described dwarfgobies,” the researchers say in the study, naming it Eviota vader after the Star Wars villain Darth […]
Evolution in overdrive as Baltic cod shrink due to fishing pressure, study shows
- The eastern Baltic cod has shrunk dramatically in size in recent decades due to rapid evolution — changes at the genetic level — caused by decades of intensive fishing, a new study says.
- Eastern Baltic cod, which are a distinct subpopulation of Atlantic cod (Gadus morhua), lost nearly half of their length and four-fifths of their weight from 1996 until 2019.
- It’s one of the first studies to show that a marine species has evolved in response to fishing pressure.
- An expert said the shrinking of the cod was “alarming,” and called on fisheries managers to work to protect fish biomass and size, given this new evidence of fisheries-induced evolution.

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

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

Small island nations provide big environmental solutions but need finance partners (commentary)
- Small island nations offer the world powerful environmental solutions — from “blue” climate finance innovations to marine conservation — but they need the international community to match their ambition with fairness and support.
- Antigua and Barbuda Prime Minister Gaston Browne argues that for Small Island Developing States (SIDS) like his, navigating uncertainty is nothing new, but these days that must be increasingly tempered with fairness, as sea levels rise and marine ecosystems struggle due to a climate crisis that they did little to abet.
- “We face growing inequities, particularly around access to ocean resources and climate finance. Between 2000 and 2023, SIDS suffered more than $30 billion in losses from climate-related disasters, yet we are locked out of concessional financing due to narrow economic metrics. This is not just unsustainable — it is unjust,” he writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Canada’s Pacific Coast hit hard by trawling, with limited transparency: Report
- Trawling vessels pursuing fish are damaging marine ecosystems in Canada’s West Coast waters and could be operating illegally in some cases, and yet they work with insufficient transparency, a new NGO report says.
- Nine large trawlers have together trawled swaths of the ocean collectively larger than the size of Ireland since 2009; they have likely trawled in prohibited zones at least 47 times and have disrupted Chinook salmon (Oncorhynchus tshawytscha) migratory routes, which are foraging areas for an endangered population of killer whales (Orcinus orca), the report says.
- A trawling industry group dismissed the NGO’s findings, saying they lacked context and the fishery was very well regulated.
- A Canadian regulatory agency said the fishery was well managed, with strict monitoring and enforcement of rules.

Sharks didn’t rebound—so Mark Erdmann is putting them back
- For over 30 years, Mark Erdmann has combined scientific discovery with grassroots conservation in Indonesia, helping communities protect their reefs from destructive practices and documenting more than 220 new species.
- As a leader behind Raja Ampat’s pioneering community-governed marine protected areas, Erdmann has shown how local stewardship can revive ecosystems—bringing back sharks, rays, and sustainable tourism.
- Despite new threats like over-tourism and revived mining, Erdmann remains hopeful, pointing to rising public resistance, tech-enabled rewilding programs like ReShark, and a new generation of Indonesian conservationists.
- Erdmann spoke with Mongabay Founder and CEO Rhett Ayers Butler during a voyage in the Pacific in June 2025.

Locals fear Chile’s new port project for green energy will disrupt ecosystems
- A new private port for public use near Punta Arenas, a city in southern Chile’s Magallanes and Chilean Antarctic Region, has been approved for multipurpose services, such as the development of green hydrogen and salmon industries.
- The region has recently attracted a lot of attention due to its enormous green energy potential.
- The company concerned told Mongabay that this port will reduce the need for developers of green hydrogen and other projects in the region to build their own private ports as there is currently a limited capacity.
- Environmental organizations and local residents fear the port’s construction and operations will impact marine ecosystems and boost industries that will likely cause greater environmental impacts, such as contamination from salmon farms.

Coral once feared extinct rediscovered in the Galápagos after 25 years
Wellington’s solitary coral, a species thought to be extinct for more than two decades, was rediscovered in 2024 near Tagus Cove in Ecuador’s Galápagos Islands, according to a recent study. Over multiple dives in 2024, scientists from the Charles Darwin Foundation, the Galápagos National Park Directorate, and the California Academy of Sciences spotted more than […]
Oil and plastic pollution from shipwreck raises concerns, legal scrutiny in India
- The MSC ELSA-3 shipwreck, off Kerala’s coast in southern India, spilled oil and plastic pellets, with potential impacts on marine life, coastal ecosystems and fishing livelihoods.
- Gaps in maritime law and weak enforcement leave India ill-equipped to handle plastic spills and wreck removal.
- Experts call for stronger spill protocols, legal updates, transparent cargo data and long-term ecological monitoring.

Antarctic coalition wins €1m prize for safeguarding a fragile frontier
The Antarctic and Southern Ocean Coalition (ASOC), an advocacy group focused on the world’s coldest and most remote region, has received the 2025 Gulbenkian Prize for Humanity. The 1 million euro ($1.17 million) award, presented by the Portugal-based Calouste Gulbenkian Foundation, recognizes the coalition’s decades-long efforts to preserve Antarctica’s ecological integrity and protect the Southern […]
A new data hub helps small-scale fishers adapt to climate change
Roughly 40% of the global fish catch comes from small-scale fisheries. It’s one of the food production systems most vulnerable to climate change, and governments are lacking data to help fishers adapt. To help address that gap, the global research partnership CGIAR recently launched its Asia Digital Hub at WorldFish’s headquarters in Penang, Malaysia. The Hub […]
Out-of-range albatross makes a highlight in the revival of seabird watching in Sri Lanka
- Sri Lanka has recorded over 50 species of seabirds — birds that spend much of their lives at sea — within its territorial waters, including several long-distance migratory birds that travel thousands of kilometers across oceans.
- As observation of seabirds is challenging, only a small group of Sri Lankan birders have focused on this unique group. In the past decade, seabird studies in the island have seen a notable revival, led by enthusiastic young birders.
- Among last year’s remarkable observations is the sighting of a grey-headed albatross off Sri Lanka’s northern coast, marking the first-ever record of the species north of the equator, well beyond its usual Southern Ocean range near Antarctica.
- World Seabird Day, observed every year on July 3, commemorates the tragic extinction of the great auk, marking the last known pair of which was killed on that day in 1844 and highlighting the vulnerability of seabirds and the urgent need for their conservation.

Restoration, protection aim to save Belize’s coral reef from extreme heat and disease
- Charles Darwin described the Belize Barrier Reef, a complex system of coral reefs, atolls and cayes spanning 300 kilometers (186 miles) and cradling the nation’s coast, as “the most remarkable reef in the West Indies.”
- Today, unprecedented coral bleaching, a relatively new illness called stony coral tissue loss disease and other threats to corals are negatively impacting reef health across Belize, according to local organizations and a recent reef health assessment.
- The government is looking to identify 20% of the reef for full protection, part of an effort to roughly triple coral reef protection from 7% to 20%.
- Meanwhile nonprofit and scientific groups are doubling down on restoration and monitoring efforts.

Will temperate seas act as refuge for coral reefs? Not in time, study says
- Some scientists have held out hope that, given the threats tropical corals face from climate change, they could improve their viability by expanding their range — by finding refuge in more temperate seas.
- However, a new study found that coral reef decline will far outpace expansion into temperate waters. Most of the damage to corals will be done in the next 40 to 80 years, but expansion will take centuries.
- The severity of coral loss will depend on levels of greenhouse gas emissions in coming decades.

Listings of Indonesian islands renew fears of privatization for coastal communities
- Listings of Indonesian islands on a foreign real estate site have sparked concerns about privatization, prompting the government to block the site domestically and clarify that islands cannot be sold to foreign entities under national law.
- Officials said the listings were likely aimed at attracting investment, not outright sales, but critics warn such practices enable control over island and offshore areas, often displacing fishers and triggering land conflicts.
- A 2021 regulation allows foreign investors to lease small islands for up to $1,900 per km² per year, and a government portal launched in 2024 streamlines permits for islands smaller than 2,000 km², accelerating commercialization.
- Watchdogs say 254 small islands have already been privatized, often without adequate oversight, and warn that unchecked investment could jeopardize fisher livelihoods and national sovereignty over maritime territories.

A Kenya marine biodiversity credit program restores mangroves — and livelihoods
- The decline of mangroves significantly weakens Kenya’s coastal protection, leaving shorelines susceptible to erosion, storm surges and rising sea levels, disrupting marine ecosystems, depleting fish stocks, leading to reduced biodiversity — and lost livelihoods for locals.
- A U.S.-based organization called Seatrees is working with the local Community Based Environmental Conservation (COBEC) and residents of Marereni to restore and protect coastal and marine ecosystems as a natural solution to climate change.
- Since 2024, Seatrees has offered donors the option of buying $3 “biodiversity blocks,” each of which represents a single tangible conservation action: planting one mangrove tree on site in Marereni.
- The work goes beyond just planting trees, as community members turn mangrove restoration into a livelihood by establishing and maintaining nurseries — and, in some cases, starting side businesses with the income.

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

Countries seek urgent CITES protection of more than 70 sharks and rays
Several proposals seeking greater protection of more than 70 shark and ray species from commercial trade were raised this week for deliberation at the 20th meeting of CITES, the global convention on the wildlife trade, to be held in November. “The world is at a tipping point for sharks and rays,” Luke Warwick, director of […]
First-ever assessment highlights threats to Atlantic cold-water corals
- A new study published in the journal Marine Biodiversity delivers the first global IUCN Red List assessments for 22 cold-water coral species in the Northeast Atlantic.
- More than 30% of the species are at risk of extinction due to bottom-contact fishing, habitat destruction and climate change, with white coral (Desmophyllum pertusum) listed as globally vulnerable.
- Experts say the findings highlight gaps in conservation, especially for deep-sea species often excluded from monitoring and protection efforts.
- The study’s release comes at a key moment, as international talks continue under the Beyond National Jurisdiction Treaty to improve high seas biodiversity protections.

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

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

As ocean acidification ramps up, experts call for speedy ocean protection
- Scientists have known for decades that soaring atmospheric carbon dioxide emissions are causing changes in ocean chemistry, threatening marine life and ecosystems.
- In June 2025, a study found that ocean acidification has passed a safe threshold across large swathes of the world’s marine environment, not only near the sea surface, but also up to 200 meters (656 feet) deep. The effect is especially severe in polar regions.
- Ocean acidification is an added stressor to marine life already facing pressure from multiple threats connected to climate change (including marine heatwaves and reduced oxygen levels in seawater), along with other direct human impacts including pollution, overfishing and deep-sea mining.
- Carbon emissions need to be deeply slashed and ocean protections greatly enhanced to allow ecosystems time to adapt and one day recover, say experts.

Vanishing giants: The Indian Ocean’s biggest fish need saving (commentary)
- New research confirms the decline of predatory and large-bodied fishes in the western Indian Ocean due to overfishing, unregulated fishing practices and climate change.
- The lead author of a new paper published in the journal Conservation Biology argues that these fish must be protected to ensure healthier reefs, marine ecosystems and adjacent human communities.
- “This issue isn’t just about protecting fish, but also maintaining a healthy ecosystem, supporting a crucial food source for millions and sustaining the livelihoods of many coastal communities. If we act now, we can still turn the tide,” the author writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

What sharks are worth—and why that matters
- Stefanie Brendl, founder of Shark Allies, transitioned from shark tourism to advocacy after a pivotal free-diving encounter with a tiger shark, leading her to champion the world’s first shark fin trade ban in Hawaii.
- Her legislative work has since expanded across U.S. states and Pacific island nations, focusing on pragmatic, economically grounded arguments for shark protection over purely emotional appeals.
- Brendl is now developing valuation models that frame sharks as renewable assets, arguing that live sharks provide far greater long-term value through ecosystem services and tourism than the short-term gains from finning.
- She spoke with Mongabay Founder and CEO Rhett Ayers Butler in June 2025 during an interview conducted aboard a boat in the Pacific Ocean.

The Caribbean’s hardiest corals (cartoon)
Despite the Caribbean Sea witnessing some of the worst episodes of mass coral bleaching over the last year, a reef in Honduras’ Tela Bay, nicknamed Cocalito, has withstood pressures from climate change and pollution, surprising and impressing marine biologists. A Honduran reef stumps conservationists with its unlikely resilience
Indigenous divers on Chile’s island restore seabed to protect seafood sources
- Intensive harvesting of the mollusk known as “loco” and salmon farming are damaging the seabed and reducing the biodiversity of the Guaitecas Archipelago, in northern Chilean Patagonia.
- To restore it, divers are transporting shellfish and rocks that serve as food and shelter for the loco and other commercially valuable species.
- The Pu Wapi Indigenous community is also working to enhance marine protection by requesting a Coastal Marine Area for Indigenous peoples.

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

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

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

Major coral loss in Vietnam’s first marine protected area: Study
- Vietnam’s first marine protected area (MPA), Nha Trang Bay, has lost nearly 200 hectares (494 acres) of coral reef since it was established in 2002, according to a new study.
- Major drivers of the coral decline include coastal development, warming sea temperatures and devastating crown-of-thorns starfish (Acanthaster planci) outbreaks worsened by overfishing and nutrient pollution.
- The study calls for stronger conservation measures inside Nha Trang Bay and other MPAs, including pollution control, active reef restoration and inclusive community governance.
- Experts say Nha Trang Bay offers lessons for other MPAs in Southeast Asia facing similar threats.

Ghana to expand artisanal fishing zone amid trawler violations
Ghana has announced plans to expand the area in which small-scale fishers can operate, in response to persistent violations by industrial trawlers encroaching into this zone. The country’s inshore exclusion zone, or IEZ, will now extend 12 nautical miles (22 kilometers) from shore, up from 6 nmi (11 km) currently. Emelia Arthur, Ghana’s newly appointed […]
Tanzania’s Mafia Island eyes sea cucumber farming to prevent extinction
Residents of Mafia Island in Tanzania don’t really eat sea cucumber; they call it jongoo bahari, or “ocean millipede” in Swahili. But sea cucumbers are a prized delicacy in East Asia, where demand has fueled a black market for the spiny sea creatures, Mongabay’s Ashoka Mukpo reported in May. A kilogram of dried sea cucumbers […]
UN Ocean Conference makes progress on protecting marine waters
- The United Nations Ocean Conference, held June 9-13 in Nice, France, saw some progress on better protecting the hundreds of thousands of species that live in marine waters and the communities that depend on the sea for work or sustenance.
- New countries committed to the high seas treaty, a moratorium on deep-sea mining and the World Trade Organization Agreement on Fisheries Subsidies, while a huge group of nations pushed for a strong global plastics treaty.
- Several countries also moved to create marine protected areas (MPAs) and reserves, or strengthen existing ones, including the announcement of the world’s largest MPA in French Polynesia.
- A wide range of groups announced other marine conservation initiatives.

The ocean is in crisis. A new effort is betting on coastal communities to save it.
The ocean has long been treated as the world’s forgotten frontier — out of sight, out of mind, and dangerously overused. Yet efforts to reverse decades of neglect are gaining momentum. Late April saw the launch of Revive Our Ocean, a new initiative helping coastal communities create marine protected areas (MPAs) to restore marine life […]
On its 50th anniversary, ‘Jaws’ continues to provoke shark conservationists
- This month marks the 50th anniversary of the release of Jaws, a Hollywood blockbuster that depicts a series of attacks by a massive great white shark — a “man-eater” — in a fictional New England beach town.
- Shark populations have plummeted since the film was released, and experts agree that Jaws misrepresented the nature of sharks and likely had a net negative impact, however small, on their population sizes and conservation status.
- Most of the experts reached for this article said the film had spurred interest in sharks, some of which was channeled in positive directions. In fact, some people who worked on the film later advocated for shark conservation.

Pelicans recover, but dolphins and other species struggle 15 years after BP oil spill
Oil-soaked pelicans struggling to fly came to symbolize the catastrophic impacts of the 2010 BP Deepwater Horizon oil spill on the inhabitants of the Gulf of Mexico. Fifteen years later, brown pelicans in the region have seen some recovery, but other wildlife species haven’t been as fortunate, Mongabay’s Liz Kimbrough reported in April. Researchers estimate […]
