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

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

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

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

Togo cosponsors proposal to review commercial whaling ban
Togo is cosponsoring a proposal to review commercial whaling quotas, drawing criticism from whale conservation groups. The draft resolution was submitted for discussion at the upcoming 70th meeting of the International Whaling Commission (IWC), which will be held Sept. 27 to Oct. 2. Togo was the only African nation to support the proposal, which was […]
Namibia greenlights controversial project to dredge phosphate from seabed
- Company Namibian Marine Phosphate has received an environmental clearance for dredging within a concession that spans 2,234 square kilometers (863 square miles) of the Atlantic seabed off Namibia’s coast.
- The company wants to mine phosphate rock, a major ingredient in fertilizers, which has previously only been commercially mined on land.
- The nonprofit Ocean Conservation Namibia (OCN) has strongly criticized the decision to issue the ECC, warning “that the large-scale development could have significant impacts on the Benguela marine ecosystem, Namibia’s fishing industry, and marine conservation.”
- NMP, registered in Namibia, is 85% owned by Oman-based Mawarid Mining LLC and 15% owned by a Namibian company, Havana Investments (Pty) Ltd.

The world’s reefs are disappearing. Coral trafficking is booming
- There are more than 1,300 documented cases since 2000 of live coral smuggling, with many cases sourcing coral from Southeast Asia, including the Philippines and Indonesia, according to data from the wildlife trade watchdog TRAFFIC.
- The cases involve at least 43 countries around the world, with the U.S. by far the biggest importer of corals.
- The cases include 3.15 million pieces of coral, with many shipments intentionally mislabeled as toys, clothes, or food to get endangered species past customs inspectors.
- Experts say there are solutions, including farm-raised coral substitutes and dyeing farmed coral to document that it was not grown in the wild, making it easier for authorities to spot illegally harvested varieties.

Gulf of Mexico’s unique Orca Basin shouldn’t become a carbon dump (commentary)
- Deep in the Gulf of Mexico, an ecosystem exists in water so salty and lacking in oxygen that its marine life is unique and virtually unstudied.
- Called the Orca Basin, it’s now the focus of a corporate effort to profit from fighting climate change by dumping tons of organic waste into its depths, a deep-sea biologist explains in a new op-ed.
- “The Orca Basin is not a waste repository waiting for a use. It is a living system that has been developing for thousands of years, hosting organisms we have barely begun to characterize, preserving a chemical and biological record we have barely begun to read,” the author argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Indigenous rangers pull killer ‘ghost nets’ from Australia’s northern coast
- Indigenous ranger groups across northern Australia are removing tons of ghost nets and other marine debris from some of the country’s most remote coastline, where abandoned fishing gear kills turtles, dugongs and sharks long after it is lost.
- The nets ride ocean currents into the Gulf of Carpentaria from Southeast Asia, and removing them is slow and dangerous work, though rangers are now using drones and AI to find nets faster than before.
- After funding for the patrols nearly lapsed, the Australian government committed AU$25 million ($18 million) over four years, most of it to continue the cleanups, and AU$4.5 million ($3.2 million) to stop nets from reaching the ocean in the first place.
- Rangers and advocates say the fix is not to blame any single country, but to address the problem at its source and keep supporting the Traditional Owners who care for this coastline.

Coastal Texas and Louisiana warned of tropical storm as a potential hurricane moves toward Hawaii
MIAMI (AP) — The National Hurricane Center issued a tropical storm warning on Monday for the Gulf of Mexico coast from the Galveston and Houston, Texas, area to the western parishes of Louisiana. As of late Monday morning, the potential tropical cyclone was centered about 120 miles (195 kilometers) south-southeast of Morgan City, Louisiana, and 230 miles […]
‘You can’t protect what you don’t know:’ Interview with marine scientist Loyiso Dunga
- The Great African Seaforest is one of the only expanding kelp forests in the world. To better understand this important ecosystem, and why it should be conserved, marine biologist Loyiso Dunga set out to map the entire forest for the first time ever in 2016 using satellite imagery.
- Dunga now works on kelp forest conservation across the globe with both the International Union for Conservation of Nature and the Kelp Forest Alliance.
- As a member of an Indigenous community in South Africa, Dunga is sensitive to how conservation measures were employed during the country’s apartheid-era to expel coastal communities, and makes sure that other scientists include coastal communities in their work.
- “There is so much knowledge that is documented within coastal communities but is outside of science,” Dunga says. “I try to spend a lot of time understanding that, which also enriches my science.”

Global sea surface temperatures reach a record high, again
Global sea surface temperatures have reached a record high, raising serious concerns for global Earth systems, according to new data released by the European Union’s Copernicus Climate Change Service (C3S). On Aug. 22, the daily global average sea surface temperature, outside polar regions, reached 21.1° Celsius (69.98° Fahrenheit), exceeding the previous record set in March […]
A sea cucumber venture in Zanzibar seeks to balance business and conservation
- For decades, conservationists have argued that protecting nature cannot rely indefinitely on donor funding. To endure, conservation efforts must generate enough economic value to sustain themselves.
- That search for sustainable financing has prompted governments, investors and conservation organizations to experiment with models that seek to align commercial returns with environmental protection.
- On Tanzania’s Pemba Island, a company called Asili is betting that sea cucumber ranching can do both. The venture is building the infrastructure needed to cultivate and process sea cucumbers for sale while supporting the restoration and protection of marine ecosystems.
- Yet, significant questions remain. Can enough sea cucumbers be produced to make the business commercially viable? Can profits be shared equitably with local communities? And can a model built around conservation and commerce truly deliver on both promises?

More than 380 coastal World Heritage Sites may face climate risks, new data shows
- Coral reefs, medieval coastal castles and mangrove forests on UNESCO’s World Heritage list now share something in common: Precise digital boundaries.
- A new dataset maps 386 coastal World Heritage Sites, offering the clearest picture yet of what stands to be lost as the world’s climate changes.
- Covering 235 million hectares (~581 million acres) of coastline, the new high-resolution, open-access dataset can be used by researchers and local managers to study flooding, erosion and other climate risks faced by heritage sites.
- The tool is a critical first step to understand climate risks, but not a substitute for the local knowledge needed to help these places survive, some experts say.

US environmental groups plan to sue to relist gray whales under Endangered Species Act
A group of environmental organizations announced their intent to sue the United States National Marine Fisheries Services (NMFS) for failing to consider protections for Eastern Pacific gray whales under the Endangered Species Act (ESA). Gray whales (Eschrichtius robustus) are experiencing a potentially catastrophic population decline, a sharp reversal from what had been considered a conservation […]
Blast fishing destroys reefs. Underwater microphones can help detect it
- Once home to a pristine and vibrant network of coral reefs, the Spermonde Archipelago off the coast of South Sulawesi in Indonesia has had its coral decimated by the illegal practice of blast fishing, in which improvised explosives are tossed into the sea to kill and stun fish en masse.
- A new study harnesses acoustic data to produce what is likely the first rigorous estimate of the frequency and intensity of bomb fishing in the archipelago.
- Using low-cost microphones and an easy-to-run algorithm, the researchers detected more than 3,500 so-called fish bombs going off in their study area within the archipelago — an average of 23 blasts a day, or almost one every hour.
- The scientists believe their approach could help communities and NGOs around the world design targeted interventions to combat the practice, which can devastate not only reefs but the broader marine ecosystems.

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

El Niño is disrupting the Pacific’s marine food web from the bottom up
As the 2026 El Niño strengthens in the equatorial Pacific, satellites are capturing the first major signs of disruption to the marine food web. According to by NASA’s Earth Observatory observations, satellite measurements show a substantial drop in surface concentrations of chlorophyll across the Central Pacific compared with neutral conditions in June 2025. Chlorophyll is […]
In Raja Ampat, children learn that their knowledge can help protect their islands
- Research suggests that children who grow up closely connected to their surroundings can develop sophisticated understandings of their local environment.
- A recent children’s book reading was part of a gathering of Indigenous communities in Arborek that brought together representatives from 20 Indigenous subtribes in Raja Ampat, as well as Indigenous people from other parts of Indonesia and abroad.
- The book turns the biodiversity of Indonesia into a visual story about what could be lost if mining damages the environment.
- The author and illustrator hope that seeing their home, animals and stories represented in a book will encourage the children to tell more stories of their own.

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

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

A deadly cross over: In South Africa, rabies moves from land animals to seals
- Cape Town, South Africa, has recorded 135 incidents of aggressive seal behavior toward humans since September 2021, including injuries that led to hospitalizations.
- Researchers suspect the cause is rabies, a disease normally associated with land animals but has leapt to Cape fur seals.
- Since May 2024, rabies cases have been confirmed in Cape fur seals along the Western Cape and Northern Cape coastlines of South Africa — the first time the virus has established itself in a marine mammal population anywhere in the world.
- Beyond attacks on humans, researchers worry whether the disease will spread to other marine mammals, as seals interact with different species.

Art and science must come together for coral reef conservation, biologists argue
Art and science can work together to raise public awareness and propel conservation efforts needed to safeguard coral reef ecosystems, a group of coral scientists argues in a new research article published in Science Advances. Coral reefs are among Earth’s most threatened ecosystems amid climate change, coral bleaching and threats from mining. However, most people […]
Angola’s peatlands highly underestimated, new study suggests
- New research mapping out the Angolan Highlands Water Tower (AWHT), a stretch of elevated plateau spanning 380,382 km², finds that a significantly larger portion of the region hosts peatland than previously thought.
- The findings show that the AWHT, named thus because it receives and regulates vast amounts of rainwater, and because it feeds important freshwater systems across southern Africa, is also a critical carbon sink.
- The research can inform national carbon policies and conservation strategies for these peatlands which store thousands of years-old carbon, experts said.
- The biggest threats to the AHWT’s peatlands are human-made including slash and burn agriculture and the unsustainable use of peat — partially decomposed plant material that builds up in waterlogged soils — which result in the release of CO2.

Spain proposes 23 new marine protected areas in the Canary Islands and Mediterranean
- The proposal represents Spain’s latest effort to advance protection of 30% of its waters by 2030.
- It looks to protect 22,405 square kilometers (8,651 square miles) of marine waters, primarily in the eastern North Atlantic Ocean around the Canary Islands, as well as four sites in the Mediterranean Sea.
- Conservation groups have raised concerns in recent years about the state of Spain’s marine protected areas, highlighting a significant discrepancy between areas designated “on paper” and those that are subject to effective protection.

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

Climate change drove extreme July heat in European seas, study finds
European coastal waters recorded unprecedented sea surface temperatures in July 2026. A new study has found that human-induced climate change primarily drove the temperature surge, pushing marine ecosystems past their limits. The rapid analysis was conducted by World Weather Attribution (WWA), a global network of researchers who analyze the influence of climate change in extreme […]
Indigenous fishers rethink shark hunting & protect species on Colombia’s coast
- In the Colombian department of La Guajira, at South America’s northernmost tip, Indigenous Wayuu fishers from the community of Punta Gallinas are working with marine biologists to conserve and document shark populations.
- Despite a 2021 law banning targeted shark and ray fishing in Colombia, the meat remains a vital protein source in one of the country’s most remote and food-insecure regions.
- Colombian shark conservation initiative Proyecto Puyuii is working with Wayuu fishers to record shark species in the understudied waters of La Guajira, implementing sustainability measures such as larger-mesh nets, safe release techniques and avoiding longlines.
- With sustainable tourism touted as a potential economic alternative to shark fishing, some fishers argue that compensation will need to be offered before they can afford to stop.

Dolphin mother and calf observed using shells to catch fish in Australia
A small population of dolphins in Shark Bay in Western Australia have a documented history of using an unusual tool to help them catch fish: Large, empty snail shells. For the first time, scientists have now observed the same behavior in a different dolphin population on Australia’s east coast. Researchers even filmed a baby dolphin […]
New Zealand opens marine reserves with groundbreaking Māori co-management model
- Five new marine protected areas (MPAs) came into effect in Aotearoa New Zealand in July after more than a decade of grassroots and governmental work — and a sixth is expected to open in the near future.
- The MPAs are no-take marine reserves, areas where all extractive activities are banned, co-managed by the regional Māori tribe Kāi Tahu and the Department of Conservation.
- The reserves are the first in the country to be co-managed by Indigenous people and the government through shared decision-making and a joint ranger team.
- The reserves are the first part of a planned network, called Te Au Roa o Te Rakihouia, which is expected to have not only the reserves but also other types of protected areas that have less strict protections.

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

On the Great Barrier Reef, management by Traditional Owners is growing
- Joint management of the Great Barrier Reef is changing, with Traditional Owners playing an increasing role in the conservation of one of the seven natural wonders of the world.
- Despite climate change continuing to threaten the health of the Reef, the World Heritage Committee has again decided not to put the Great Barrier Reef on its “in danger” list, and has cited increased levels of Traditional Owner management in its decision.
- Traditional use and management agreements currently cover 43% of the Great Barrier Reef’s coastline and the government has announced new funding and measures to further include Indigenous management.
- There are still gaps in the full inclusion of Indigenous communities in the stewardship of their traditional waters, say Indigenous governance organizations, though strides are being made.

As an industry and a cooking ingredient, seaweed is gaining ground in Brazil
- In Paraty, Brazil, a Caiçara family has transformed seaweed cultivation into gastronomy, educational tourism and a source of income. The venture is driven by strong female participation and a deep connection to their territory.
- Originally introduced in Brazil to supply the carrageenan industry, the macroalgae Kappaphycus alvarezii is also being used as a biofertilizer and increasingly as a food item..
- Its farming also supports ecological balance. It produces oxygen, absorbs carbon and helps improve water quality by filtering out excess nutrients.
- Experts say the expansion of seaweed farming in Brazil faces bottlenecks in credit, marketing, technology and regulation. New research networks and public policies are attempting to organize the sector as part of the country’s growing bioeconomy.

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

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

South Africa’s top court blocks Shell oil exploration off country’s Wild Coast
In a landmark judgment on Aug. 14, South Africa’s Constitutional Court set aside exploration rights held by oil giant Shell and Impact Africa, a South African oil and gas company. The ruling prevents the companies from exploring for fossil fuels off South Africa’s Wild Coast. The case was brought by Wild Coast communities and environmental […]
Global marine protected areas fail to safeguard most sharks and rays: Study
- Marine protected areas (MPAs) cover less than 10% of the ranges of most species of sharks and rays, with significant shortfalls for threatened and critically endangered species, a new study finds.
- The analysis also reveals major gaps in reporting on the extent of fishing and harvesting re-strictions in these preserves.
- The study’s authors recommend including biodiversity targets as part of the 30×30 framework and encourage policymakers to consider aligning MPAs with important shark and ray areas to maximize conservation and biodiversity benefits.
- However, some researchers disagree that blanket MPAs would meaningfully benefit shark and ray conservation.

Sand mining plans spark opposition from fishers in Indonesia’s Riau Islands
- Plans to mine marine sand off Indonesia’s Numbing Island have sparked opposition from fishers, environmental groups, and some lawmakers who warn of damage to fishing grounds and marine tourism.
- Although the government describes the project as marine sediment management and no company has begun operations, the proposal has divided local communities over the promised compensation.
- Critics warn the dredging could increase water turbidity, damage coral reefs, alter coastal currents, and weaken natural coastal defenses.
- The dispute has also raised legal and geopolitical concerns, with researchers arguing the Riau Islands’ strategic location makes the environmental risks a national security matter.

Six African countries now support precautionary pause on deep-seabed mining
Three more African countries have joined calls for a precautionary pause on deep-sea mining until the environmental, social and economic impacts of such mining are better understood. This brings the number of African countries supporting a moratorium to six. Mauritius, Mozambique and the Republic of the Congo announced support for the precautionary pause during the […]
Illegal mining threatens Ghana’s first marine protected area
- Illegal gold mining in Ghana’s Greater Cape Three Points Forest Reserve threatens vulnerable and endangered species in the protected forest, say conservationists.
- Sediment and toxic chemicals from the mining also threaten the adjacent waters of a newly declared marine protected area just offshore.
- Conservation NGOs want the government to act against illegal miners, including establishing permanent camps in the forest to protect a wider area.

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

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

As Canada’s captive belugas arrive in the US, questions linger about their future
- Thirteen beluga whales from a pod of about 30 languishing in the shuttered Canadian marine park Marineland arrived in the U.S., six of them on July 21, and seven on August 3, as part of an emergency rescue of these captive cetaceans.
- The transfers come after nearly a year of jostling between the Canadian government and Marineland about the belugas’ future, amid threats of euthanasia and disagreements over where the cetaceans should be housed.
- Earlier this year, several U.S. aquariums drew up an emergency rescue plan to transfer these cetaceans to four U.S. facilities.
- Conservationists say the U.S. move leaves questions unanswered about the cetaceans’ future, including if they would be used for entertainment or bred in captivity — both outlawed in Canada since 2019.

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

On a Philippine beach, villagers are stepping up to save sea turtle nests
Beaches in San Vicente municipality in the Philippines’ Palawan province are crucial nesting grounds for olive ridley sea turtles. But the turtles and their babies face perilous journeys on those beaches — from dogs, tourism, and increasingly severe storms and high tides. To counter these threats, the NGO Large Marine Vertebrates Research Institute Philippines (LAMAVE) […]
What happens after a whale strands on a Mumbai beach?
On the morning of June 27, a 7.6-meter (25-foot) blue whale calf washed ashore on a busy beach in Mumbai, India’s financial capital and the capital of Maharashtra state. Whale strandings are rare along the Maharashtra coast, so Mongabay spoke with experts to find out what happened next. “Each stranding incident is a totally unexpected […]
Mining threat persists in Raja Ampat, Indonesia’s ‘Amazon of the Seas’
- The Indonesian archipelago of Raja Ampat is home to some of the world’s richest marine biodiversity.
- A year ago, the Indonesian government suspended mining activities for review and later revoked the permits of four of the five nickel companies operating in Raja Ampat following a public backlash.
- According to a new Greenpeace report, Raja Ampat remains vulnerable to nickel mining, with three companies still pursuing mining rights on its largest island and state-owned PT Gag Nikel continuing to operate.

Papua New Guinea, Vanuatu, and Fiji announced the Melanesian Ocean Corridor of Reserves in May. Solomon Islands joined in […]
Deep-sea snails and mussels in Indian and Pacific Oceans contain microplastics, study finds
- A new study has found microplastic particles in almost all sampled mussels and snails inhabiting deep-sea hydrothermal vents in the Indian Ocean and southwestern Pacific Ocean.
- By comparing snails and mussels from hydrothermal vents in two oceans, researchers found stark differences in levels of microplastic contamination between the two.
- The new study suggests the animals’ different feeding mechanisms might influence the amount of plastic pollution in their bodies.

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

Coral reef experts press on, with climate looming over international conference
- Coral reef scientists, conservationists, policymakers and community leaders from more than 90 countries met July 19-24 at the International Coral Reefs Symposium in Auckland, Aotearoa New Zealand.
- Participants discussed how to combat the drivers of climate change, how to characterize and communicate the current condition of coral reefs, and how to empower Indigenous communities and integrate their knowledge systems, among other topics.
- During the week of the conference, a new U.S.-based coral reef research center was launched and the first-ever high-resolution mapping of living corals for the Pacific Ocean was announced.
- The next International Coral Reef Symposium will take place in Rio de Janeiro, Brazil, in July 2030.

Listening offers a clearer picture of India’s hidden finless porpoises
The Indo-Pacific finless porpoise is one of India’s smallest cetaceans, inhabits turbid coastal waters, and lacks a dorsal fin — all of which make it a difficult species for researchers to spot. Recent research suggests these animals are far more prevalent in Indian waters than visual sightings suggest, yet they may be disappearing before they […]
Wind farms join bottom trawlers and oil rigs in a protected North Sea sandbank
- Dogger Bank is a vast, shallow sandbank in the North Sea that was once among the most productive marine nurseries in Europe, prompting experts to call it the ecological heart of the North Sea.
- While much of Dogger Bank has been protected for its unique seabed habitat, destructive industrial activities like oil and gas extraction as well as fishing practices like bottom trawling have continued, even in the protected zones.
- Now, conservationists have notched a win with a recent court ruling that curtails bottom trawling in Dogger Bank.
- However, they say the threats continue, notably in the form of major wind farm developments rising in a protected area.

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

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

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

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

Scaling up offshore wind requires overcoming global and local challenges
- Offshore wind has great potential as a renewable source of energy, experts say, but remains underutilized; its pace of development is slower than needed to meet set climate goals.
- As a sector, offshore wind is buffeted by global economic factors, such as inflation and supply chain constraints. That’s led to failed auctions and canceled projects in recent years.
- Other challenges at the national level, such as ensuring timely grid connections and ship and port capacity, have also emerged.
- These must be overcome if offshore wind is to scale, according to experts.

Extreme weather dampens breeding success for marine predators in Tasmania: study
- A recent study found that extreme weather events like storms, heat waves and floods can interfere with the breeding success of marine predators like seals, shearwaters and albatross that raise their young along the coasts of the Australian state of Tasmania.
- While some colonies appeared unaffected by extreme weather, others saw offspring swept away by powerful waves and storm surges, hypothermia during unusually wet episodes, and deadly overheating during periods of high temperatures.
- The researchers noted that these extremes are among many challenges seals, seabirds and other marine predators face, including pollution, disease and declining food supplies, which can also be influenced by extreme weather events.

Finning the High Seas
This investigative series uncovered a massive illegal shark-finning scheme and widespread labor abuses across the fleet of Dalian Ocean Fishing (DOF), a major Chinese tuna company with dozens of boats operating in international waters. Reporters tracked down and interviewed some two dozen Indonesian deckhands who worked aboard the company’s vessels, documenting their experiences with excessive […]
Winners of the annual Mangrove Photography Awards: See the photos
In celebration of World Mangrove Day on July 26, the U.S.-based Mangrove Action Project (MAP) has announced the winners of its 12th annual photography awards. “Mangroves are the underdog. They will never be as glamorous as the Amazon rainforest or coral reefs. But through photography we can change that narrative, and intrigue people by showing […]
New treaty promises safer conditions for Indonesia’s fishing crews
- Indonesia has ratified the ILO Work in Fishing Convention (ILO 188), committing to stronger protections for fishing crews, including safer working conditions, fairer pay and better access to health care.
- Labor groups say the convention could close long-standing legal gaps that have left many domestic fishing workers vulnerable to poor conditions and weak oversight.
- Experts say stronger labor standards could also help curb illegal fishing and boost the credibility of Indonesian seafood exports in markets with strict sustainability requirements.
- The biggest challenge now is implementation, with the government facing a year to update regulations and improve enforcement, training, and support for the fishing industry.

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

Sea salt in Lombok Island, Indonesia is contaminated with microplastics: study
Sea salt sold in markets across Lombok Island, Indonesia, is contaminated with microplastics, according to a recent study. Microplastics are small plastic particles less than 5 millimeters in length that form when larger plastic waste breaks down. Microplastics have been found everywhere scientists have looked for them, including seafood and table salt, raising concerns for public […]
How saline drinking water raises preeclampsia risks in coastal Bangladesh (commentary)
- Climate change and rising sea levels are driving salt water intrusion into drinking water sources in coastal Bangladesh, which research links to an increased risk of preeclampsia, a leading cause of maternal mortality.
- Rural communities lack adequate freshwater infrastructure, which means pregnant women are often forced to consume saline water, making them particularly vulnerable to the life-threatening effects of excessive sodium intake.
- To address this hidden health crisis and prevent further maternal deaths, Bangladesh’s government and partner organizations must take urgent action by subsidizing household rainwater harvesting tanks for the most vulnerable coastal families.

As Australia expands seismic testing, experts warn of profound effects on sealife
- Research has shown the intense, impulsive underwater noise from marine seismic surveys can harm marine animals up and down the food chain. Yet marine scientists say major gaps remain in understanding how the effects of repeated exposure may accumulate across ecosystems over time.
- Even so, the technology is becoming embedded in Australia’s energy transition plans, as projects increasingly rely on seismic surveys not only to search for gas, but also to repeatedly monitor sites where carbon dioxide captured during gas production would be injected permanently into seabed rock formations.
- The process, known as carbon capture and storage, is relatively new, and while proponents say it is the only way to reach net zero goals, major economic and performance challenges remain.
- The expansion of carbon capture and storage could make seismic surveys a recurring feature of Australia’s net-zero ambitions.

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

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

Oystercatchers, known for sharp bills and beady eyes, are making a comeback thanks to conservation
SOUTH KINGSTOWN, R.I. (AP) — A shorebird known for its sharp, orange bill and beady eyes is making a comeback in North America thanks to a yearslong conservation effort. The American Oystercatcher was nearly wiped out on the East Coast at the turn of the 20th century due to hunting and egg collecting. But the […]
Félix Guillermo Moncada Gavilán helped move Cuba from sea turtle fishing to protection
For much of the 20th century, Cuba’s sea turtles were treated as a fishery. Green turtles were taken for meat, and hawksbills for the patterned shell used in jewelry and ornaments. In the 1980s, legal fisheries landed an average of 836 metric tons a year. Research focused in part on how the catch might be […]
US government announces plans to lease deep-sea mining rights in American Samoa
The U.S. government has taken another definitive step toward launching a deep-sea mining industry, starting in the waters of American Samoa, despite public opposition. On July 17, the Marine Minerals Administration (MMA), a new U.S. agency formed by merging the Bureau of Ocean Energy Management and the Bureau of Safety and Environmental Enforcement, announced intentions […]
How a community is helping sea turtles hatch in the Philippines
- The municipality of San Vicente in the Philippines’ Palawan is a vital nesting ground for Olive Ridley sea turtles.
- Nesting turtles and their eggs face an array of challenges. Predation by dogs is the most immediate threat, but rising sea levels, more severe storms and tourism development plans also loom large.
- To try to protect the turtles, Large Marine Vertebrates Research Institute Philippines, a Philippine-based NGO, runs a research project and works with paid patrollers to monitor and protect turtles and their nests.
- Community involvement is key to the group’s conservation efforts.

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

Gray whales are suffering catastrophic population decline in the Pacific Ocean
Gray whales are experiencing a potentially catastrophic population decline, a sharp reversal from what had been considered a conservation success. As of July 6, 2026, there were 145 gray whale (Eschrichtius robustus) stranding deaths in the Pacific, according to National Oceanic and Atmospheric Administration (NOAA) data. The environmental non-profit Public Employees for Environmental Responsibility (PEER) […]
Invasive giant prawn spreads through protected areas in Brazil
- A study led by researchers from Brazil and Uruguay confirmed the presence of invasive prawns in several conservation areas along the Brazilian coast, including estuaries listed by UNESCO as Natural World Heritage Sites.
- Considered an opportunistic predator and highly adaptable to different marine conditions, the giant river prawn competes with native species for food and shelter, in addition to being a potential vector for diseases.
- While scientists demand concrete actions to stop the advancement of this intrusive crustacean, small-scale fishers report significant drops in their capture of native animals, warning about the impact of invasive species on their livelihoods.

Deep sea mining identified as biggest threat to known and unknown deep-sea creatures
In its most recent update to the Red List of threatened species, the International Union for Conservation of Nature (IUCN) identified deep-sea mining as the biggest threat to a critically endangered deep-sea snail. Discovered in 2021, scientists named the mollusk Lirapex felix — the lucky lirapex — because of the luck it took to find […]
Bill Montevecchi showed what seabirds could tell us about the sea
- Bill Montevecchi spent more than five decades showing how seabirds could reveal changes in the North Atlantic, helping establish them as indicators of ocean health, fisheries, pollution, and climate change.
- Based at Memorial University in Newfoundland, he combined field research with public communication, believing scientists had a responsibility to explain their work beyond academic journals.
- His research informed marine conservation, fisheries management, and environmental policy, while his mentorship and interdisciplinary collaborations influenced generations of seabird scientists.
- Montevecchi approached birds as sources of evidence rather than symbols, arguing that careful observation and rigorous science offered one of the clearest ways to understand a rapidly changing ocean.

Rising seas, garbage and heat threaten Brazil’s migratory shorebirds
- Among the many effects linked to climate change and damages to estuarine ecosystems, research indicates that migratory birds that depend on coastal wetlands could lose half of their habitats by 2050
- The impact is significant for Brazilian shorebirds: besides depending on a continuous chain of healthy wetlands to complete their long journeys between hemispheres, they suffer from the degradation of feeding areas such as mangroves.
- One the most threatened species is the red knot (Calidris canutus): low food availability could impair the bird’s preparation for the 8,000-kilometer (5,000-mile) journey it makes from Brazil’s northeast coast to the U.S. coast.
- Researchers are conducting censuses and conservation projects in areas of high shorebird biodiversity, including the Potiguar Basin in Brazil’s Rio Grande do Norte state, considered a “regionally important site” for these migratory birds.

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

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

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

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

What will Africa’s story on ocean governance be? Interview with David Willima
- With the High Seas Treaty in force, African proposals to designate marine protected areas in international waters are taking shape.
- Maritime security expert David Willima talks about why the West African marine protected area proposal is advanced and why others still require careful coordination.
- Willima says that with the current transformation marine governance is going through, African countries need to be actively engaged in order to have a voice in global decision-making.

Scientists use AI to produce first high-resolution map of global seagrass extent
- Scientists have produced the first high-resolution map of seagrass ecosystems around the world.
- Data from the map reveal that 70% of global seagrass cover is concentrated off the coasts of just five countries.
- The map also found that nearly 80% of seagrass loss happened outside marine protected areas, emphasizing the importance of targeted conservation action.
- Seagrass ecosystems play an important role in protecting coastlines and carbon sequestration; however, they face threats from hurricanes, coastal development, and marine heat waves.

Can conservation change how the world sees the Strait of Hormuz? (commentary)
- If seen only as an oil corridor, the main question becomes how to keep energy moving, but this overlooks a much more important reality, that the Strait of Hormuz is biologically rich yet fragile.
- Featuring mangroves, seabird colonies, coral reefs, turtle nesting beaches and islands, it is a narrow ecological corridor through which the Persian Gulf exchanges water between the Gulf of Oman and Indian Ocean, connecting nature across borders.
- “If it is also seen as an ecological corridor, another question enters the room: how much ecological capital is the region willing to risk while trying to protect its political and economic capital?” a new op-ed asks.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

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

Could a blighted urban inlet become a global beacon of waterway renewal?
- A group of advocates is seeking to transform False Creek, a tidal inlet in Vancouver, Canada, from a polluted city inlet into a place where nature thrives and people can safely swim in the water.
- Facing jurisdictional challenges over who gets to decide the future of this once vital marine ecosystem, advocates have explored various governance models for the inlet, such as getting it designated as an urban marine park or granted environmental personhood.
- Not everyone agrees, and now, they are pushing for the surrounding community to voice their desires and negotiate for False Creek’s future.

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

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

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

Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Mohammed Abu Daya is a marine ecologist from Gaza. His work focuses on spinetail devil rays, also known as giant devil rays, a critically endangered species that moves through the Mediterranean and beyond. Few scientists specialize in these […]
As East Africa’s oceans change, coastal women build new livelihoods
MALINDI, Kenya (AP) — Across East Africa’s coastline, climate change and industrial fishing are threatening the livelihoods of millions who depend on the ocean. In Kenya, women are turning to community tourism, mangrove restoration and other nature-based enterprises as declining fish stocks force them to adapt. Their experiences mirror a regional push to strengthen coastal […]
Listen to whales to improve connection, care & ocean health (commentary)
- From establishing conservation protections to developing tools to understand whale communication, the work of marine biologist David Gruber and oceanographer Sylvia Earle is grounded in the same belief: understanding leads to connection and care.
- While there have been remarkable conservation successes across the five decades of their efforts, the overall trend is clear: the health of the ocean is declining faster than efforts to protect it.
- “We still have an opportunity to leave future generations an ocean filled with life, wonder, and possibility. But this window is closing. The choices we make in the next decade will firmly shape the future of marine ecosystems,” the co-authors argue.
- This article is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Sightings off Southern Africa suggest blue and fin whales may be rebounding
Sightings of blue whales and fin whales off Southern Africa’s Atlantic coast have increased in recent years, according to a newly published study. This could signal recovery of the marine mammals after being virtually eliminated from the area by commercial whaling in the 20th century, the study authors say. Scientists estimate around 350,000 Antarctic blue […]
Australia’s seagrass meadows under pressure as climate change turns up the heat
- Australia is a global stronghold for seagrasses, the flowering plants that grow in coastal waters and bays.
- Seagrasses are unsung but vital ecosystem engineers: They stabilize sediments, provide habitat and food for marine species, help cleanse the water column of pollutants and sequester vast amounts of carbon dioxide.
- Across Australia’s waters, these undersea meadows are suffering as coasts are developed, seas are polluted and climate change continues to raise water temperatures.
- Conservationists are working to restore seagrasses and build resilience to preserve these vital marine ecosystems.

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

Rare fungi help restore Palmyra Atoll rainforests, new study finds. Here’s how
Palmyra Atoll in the North Pacific is one of the most remote island systems on Earth. A native rainforest tree on the island performs a critical ecological service by providing nesting sites for thousands of seabirds, whose guano fuels the surrounding coral reefs. But a new study revealed that this entire cycle depends on an […]
Indonesia’s ratification of fishing labor reforms will also boost conservation (commentary)
- Indonesia’s formal ratification of the ILO Work in Fishing Convention is a historic milestone for workers and will boost the sustainability of the fishing industry, the writer argues.
- Such reforms require a broad coalition beyond traditional labor actors and must include fisheries authorities, fishing companies, fishers’ organizations and conservation groups.
- “Fishers working under safer and fairer conditions are more likely to engage in responsible fishing practices and support conservation measures,” the author writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Sightings of humpback whales surge in Rio de Janeiro, fueling demand for whale-watching trips
RIO DE JANEIRO (AP) — Sightings of humpback whales off Rio de Janeiro’s coast are surging as they recover from decimation due to commercial whaling, prompting an acceleration in the demand for whale-watching excursions to spot the huge marine creatures during their annual migration. The species’ population has jumped from around 2,000 to around 35,000 […]
Can coastal infrastructure be engineered to harbor marine life instead of harming it?
- Living Seawalls is a global initiative that aims to make seawalls, marinas and other hard coastal structures more hospitable to marine wildlife by installing biodiversity-friendly panels, boulders and pilings.
- In 2025, Ireland’s first Living Seawalls installation was established at Kennedy Pier in the port town of Cobh, and marine life is already starting to colonize the panels.
- While researchers say the panels can help marine life colonize hardened coastlines, and stayed cooler than standard flat seawall surfaces, questions remain about their effect on seawalls’ main function of keeping waves at bay, leading scientists to suggest that design modifications may be needed.

Sea level rise is ruining coastal Bangladesh with salty water (commentary)
- Projections indicate that Bangladesh faces an amount of sea level rise that will bring major saltwater intrusion into precious freshwater supplies, plus human health impacts, flooding and rampant erosion across coastal areas.
- Though Bangladesh did very little to cause climate change, the nation is not without answers, including the government’s Delta Plan 2100, but it is not moving quickly enough to act on them in time to avoid the worst impacts, the author writes.
- “What has been missing is not knowledge or technology, but the institutional will to treat this like the emergency that it is,” the writer argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

A marine heat wave caused seabird deaths off California. El Nino could worsen the die-off
SAN DIEGO (AP) — Many seabirds are starving to death as a marine heat wave lingers off California and fish seek deeper, cooler waters. That’s according to scientists who say a persistent marine heat wave has shrunk the band of cold, nutrient-rich surface water where krill, anchovies and sardines thrive near the shore. Scientists fear […]
Wildlife’s unpredictable movements make climate-change planning difficult
- Ecologists expected many species to shift northward or upslope in response to warming temperatures, but only about half of observed range shifts so far align with their projections.
- Species responses are likely shaped by multiple factors — changing habitat, rainfall and food availability — not just temperature. Some species may be unable to move, trapped within a fragmented habitat.
- Research shows animals that move toward higher latitudes don’t necessarily fare better.
- These mismatches between predictions and reality create more uncertainty for conservation planning and how best to support species adaptation through corridors.

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

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

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

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

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

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

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

Chewing sounds can help decode an animal’s diet using AI, new study finds
- Scientists have developed an AI model that can listen to the chewing sounds of predators and identify what they are eating.
- The tool was trained with audio of whitespotted eagle rays crushing open shells of the mollusks they are preying on.
- It’s crucial to understand predator-prey interactions to figure out the resources the predator depends on and the pressure it puts on prey.

Not all coral reefs are doomed as a result of climate change, study suggests
One third of the world’s coral reefs may be able to withstand the impacts of climate change by 2050, according to a study conducted by the conservation NGO Wildlife Conservation Society and researchers from Macquarie University in Australia. The findings of the study, yet to be peer-reviewed, were presented on June 16 during the Our […]
In Kenya’s Mida Creek, fishers confront a changing ocean with hope
- Scientists say that the oceans are warming and absorbing more than 90% of the excess heat trapped by greenhouse gases in the atmosphere. These rising temperatures are placing growing stress on marine ecosystems, fueling coral bleaching, disrupting breeding cycles of marine organisms, and reshaping fish habitats.
- In the Western Indian Ocean – including along Kenya’s coast – warming is occurring faster than the global average in some places, raising fresh concerns for communities whose food security and livelihoods depend on the sea.
- Along the shores of Mida Creek in Watamu, one of Kenya’s best-known coastal destinations on Kenya’s Indian Ocean coast, fishers say they are already feeling the effects. Many report traveling farther offshore in search of fish and returning with smaller catches than they did a generation ago.
- During a recent reporting trip, Mongabay met fishers and women involved in the fish value chain who spoke about declining catches and fears for the future. At the same time, they pointed to local efforts to restore mangroves, protect fish breeding grounds, and clean beaches as reasons to hold on to hope for Mida Creek’s future.

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

An island community in Thailand works to protect and revive its dugongs
Once a lush field of green, the seagrass meadows surrounding Thailand’s Koh Libong are now largely barren stretches of sand, devastating the island’s iconic dugong population, reports Mongabay’s Carolyn Cowan. Koh Libong’s seagrass meadows were once Thailand’s largest, and a critical coastal habitat that is protected nationally. Yet, between 2020 and 2024, seagrass cover in […]
Studying giant devil rays through war in Gaza: Interview with Mohammed Abu Daya
- Mohammed Abu Daya is a marine ecologist in Gaza. His research focuses on spinetail devil rays, a large-bodied species of ray that roams the Mediterranean Sea and beyond.
- Since 2013, Abu Daya has monitored the impact that local fisheries have on spinetail devil rays, which are listed as “critically endangered” on the IUCN Red List. Palestinian fishers occasionally target the rays when they stray into Gaza’s coastal water, as other fishing resources in the area have been depleted due to longstanding Israeli restrictions.
- Displaced by Israeli bombings during the war in Gaza that began in 2023, Abu Daya now lives in a tent, with limited access to basic necessities like food and drinking water, or to the internet. His university office has been destroyed, and he can no longer conduct research at sea. Yet he continues to carry out his scientific work, in the hope that it will help improve the conservation of devil rays globally.
- In 2025, at the height of the war, Abu Daya co-authored an international research paper documenting the behavior of spinetail devil rays and showing the importance of the Levantine region for the conservation of this species.

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

To help combat illegal fishing, 15 countries commit to sharing fisheries data
Fifteen countries from Africa, Asia, Latin America and Europe adopted the Mombasa Declaration on June 17, 2026. Together, they committed to advance global fisheries transparency and strengthen efforts to combat illegal, unreported and unregulated (IUU) fishing. The declaration was adopted during the 11th meeting of the international Our Ocean Conference, held in Mombasa, Kenya. Africa […]
New walking shark discovered in Papua New Guinea
Researchers have described a new-to-science species of walking shark, which lives in the remote, shallow waters off southeastern Papua New Guinea. The newly named Dudgeon’s walking shark (Hemiscyllium dudgeonae) is a type of epaulette shark, a group of small sharks famous for their ability to use their fins to “walk” when stranded in tidal shallows. […]
French Polynesia expands ocean protections to 30% of its waters
The government of French Polynesia announced it is expanding the extent of ocean where extractive industries like seabed mining and industrial fishing will not be allowed. With this move, 30% of French Polynesia’s waters will now be fully protected. Last year on June 8, French Polynesia, a French overseas territory, established the Tainui Atea marine […]
Protect Antarctic krill to preserve the health of Africa’s coastal communities (commentary)
- African leaders must demand an end to industrial krill fishing in the Southern Ocean while at the Our Ocean Conference this week, before irreversible damage is done, Angola’s Minister of Fisheries and Marine Resources warns in a new op-ed at Mongabay.
- Antarctica and the ocean systems upon which Africa depends rely on krill — the tiny crustacean that gathers in huge swarms and which whales, seals, penguins and fish species feast upon — so letting business interests dictate how the base of this important food chain, that millions of people also benefit from, is irresponsible, she writes.
- “What happens in Antarctica affects the global ocean. That means the whales migrating along African shores, the resilience of our coastal communities, and the health and livelihoods of our coastal communities,” the minister argues. “Please join me in calling for an end to krill fishing now.”
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Africa’s community-led marine organizations on which 30×30 depends
- More than 5,000 delegates are gathering in the Kenyan coastal city of Mombasa for a major global conference on the future of the oceans.
- At the heart of the discussions is ocean governance and the global push to meet the 30×30 target — protecting 30% of the world’s land, freshwater and oceans by 2030.
- But meeting that goal will depend not only on governments and international pledges, but also on community-led organizations doing the difficult work of conserving fragile marine ecosystems.
- Across Africa and around the world, thousands of grassroots groups are carrying out this work, often far from the spotlight, helping shape ocean conservation and blue economies that support local livelihoods. Mongabay spoke with representatives of four such organizations working across the continent from the Western Indian Ocean to Africa’s Atlantic coast.

‘Thinking how traffickers think’: Study uses AI to detect marine wildlife smuggling
- Researchers have developed what they say is the first AI algorithm dedicated to detecting trafficked dead marine wildlife from 3D X-ray images.
- The system was most effective at finding species with idiosyncratic shapes, like shark fins and seahorses, but also detected sea cucumbers with 86% accuracy.
- Interpol seized more marine specimens than reptiles, birds and primates combined in 2025, but experts say the illicit trade remains underrecognized compared to tracking of terrestrial animals and their parts.
- The effectiveness of the new approach may be limited by access to 3D X-ray machines in airports and mail pathways, and when officials try to distinguish between species in the same genus.

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

Lawmakers fight to stop the Trump administration’s dismantling of a $386M ocean observatory project
SEATTLE (AP) — Lawmakers are demanding the National Science Foundation stop dismantling the Ocean Observatories Initiative, a $386 million ocean monitoring network being wound down under President Donald Trump’s administration. House Democrats on two committees call the action illegal. Democratic Sen. Jeff Merkley says he’s drafting legislation to freeze the removal of instruments until a […]
Plastic food packaging blankets the world’s coastlines, study finds
- A new study analyzed thousands of shoreline litter surveys and other data from more than 100 countries to produce the first global index of macroplastic pollution by type.
- The study found food and beverage plastics were the most common litter type for 93% of countries surveyed, followed by plastic bags and cigarettes; the pattern was consistent across countries, regardless of waste management infrastructure.
- Plastic pollution harms marine life and disrupts ecological services provided by coastal ecosystems like mangroves, coral reefs and seagrass.
- Researchers call for reducing production, warning that waste management alone will not solve the global plastic pollution problem.

Australia establishes the first Sea Country Indigenous Protected Area
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. For the Karajarri people of Kimberley in northwestern Australia, the coastline, reefs, wetlands, beaches and desert-edge country form one estate, held through law, memory, work and obligation. That relationship now has new recognition, reports Mongabay’s John Cannon. In […]
Researchers find dramatic restoration on land and sea after island rat removal
When invasive rats are removed from islands, the ecological benefits can ripple across both land and sea more quickly than scientists expected, according to recent research. Scientists have long assumed that meaningful recovery after the predators are eradicated would take decades. However, researchers with the U.S.-based NGO Island Conservation conducted a rat-removal experiment on Ulong Island […]
‘Flamingo Revolution’ aims to stop Kushner-backed resort on protected Albanian delta
- In April, Albanian authorities allowed bulldozers to tear through the protected Vjosa-Narta delta — home to flamingos, loggerhead sea turtles and the endangered Mediterranean monk seal — without permits or environmental review, sparking mass protests that have shaken the government of Prime Minister Edi Rama.
- The construction is linked to a luxury resort backed by Jared Kushner’s Affinity Partners, targeting one of the last intact river-delta wildernesses in the Mediterranean, where only 4% of deltas remain undisturbed.
- As Albania’s anti-corruption authority investigates and the EU warns the development could jeopardize the country’s 2030 membership bid, conservationists say the crisis exposes a pattern of broken promises around the celebrated Vjosa Wild River National Park.

Pilot whales can’t hear each other over ship noise in Strait of Gibraltar, study finds
The rumble of ship traffic is drowning out the calls of long-finned pilot whales and potentially other marine species in the Strait of Gibraltar, a narrow strip of water between Morocco and Spain that separates the Atlantic Ocean from the Mediterranean Sea. Researchers who investigated this looked at near and long-distance communication between long-finned pilot […]
Global ocean faces ‘deepening crisis,’ but governance is improving: UN report
- On June 8, the U.N. released its third World Ocean Assessment, a comprehensive report on the state of the global ocean between 2021 and 2025, compiled by around 600 experts from 86 countries.
- The report highlights a deepening crisis for the global ocean, as human pressures, including pollution, overfishing and climate change, strain marine ecosystems already under extreme pressure.
- It notes that ocean governance is improving, and that models that incorporate Indigenous, traditional owner and local community knowledge are likely to achieve better outcomes.
- However, it also warns that ocean governance remains “fragmented” and insufficient to address the scale of the challenges facing the world’s oceans.

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

‘Chemical cocktail’ of pharmaceuticals found in Djibouti coastal waters
Common medications that billions of people take for ailments like pain, fever and infections were detected in several sites along Djibouti’s Gulf of Tadjourah in East Africa, according to a recent study. Researchers found that untreated urban wastewater contained dangerous concentrations of anti-inflammatory medicine like ibuprofen, caffeine, and the antiepileptic drug carbamazepine, which were contaminating […]
In Indonesia’s Lombok, fishers find food security tied to mangrove reforestation
- On the east coast of Indonesia’s Lombok Island, local people who rely on the local crab fishery have initiated their own mangrove planting program in a bid to resuscitate failing crab habitats.
- The system is known as a silvofishery, which integrates mangrove forests with aquaculture cultivation to raise productivity.
- Instead of catching immature crabs from the coastline for quick sale, some local fishers have started to raise the crabs to adulthood alongside newly planted mangroves, garnering a higher price while overseeing a more sustainable population.
- However, local officials say a lack of technical training means most silvofishery initiatives have been forged through trial and error, and that expanding the system could result in greater mangrove planting in addition to boosting purchasing power in subsistence communities.

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

Experts say ‘bare bones’ US laws are unfit to regulate nascent deep-sea mining industry
- As the U.S. government prepares to auction off slices of the seabed in federal waters, experts, including the former director of the federal agency overseeing deep-sea mining, say the regulations that would govern this activity are outdated and lack important oversight provisions.
- The Bureau of Ocean Energy Management recently proposed revisions to its rules to streamline leasing and permitting, but critics argue these revisions would weaken oversight by reducing environmental review requirements and limiting opportunities for public input.
- One expert also warned that the U.S. government’s classification of seabed resources as a source of critical minerals may increase the likelihood of exemptions from environmental protections.

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

World Oceans Day: Marine protected areas surpass 10% mark in 2026
World Oceans Day is celebrated every June 8 to raise awareness about the conservation of Earth’s oceans. In honor of World Oceans Day 2026, the United Nations is focused on marine protected areas (MPA), and the goal of protecting 30% of the world’s oceans by 2030. The world collectively reached a third of the goal […]
‘Slumping’ afflicted soft corals around a South Korean island in 2024. Will it return this year?
- In 2024, scientists and conservationists documented a soft coral “slumping” event along the southern coast of South Korea’s Jeju Island, which led soft corals to lose their shape, droop, and even die in vast numbers.
- The event coincided with record heat and rainfall, which has led scientists to surmise, in a new paper, that the “slumping” resulted from a combination of thermal stress and changes to salinity and water quality.
- However, further research and testing is needed to determine the actual cause, researchers say.
- Scientists and conservationists say that while widespread slumping did not occur during 2025 or so far in 2026, the “Super El Niño” predicted for later this year could impact Jeju’s soft corals in a similar way.

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

Tuna are rebounding. The work is far from done.
Tuna offer a useful case study for World Ocean Day because their recovery has come through the least sentimental parts of conservation: quotas, enforcement, stock assessments, and years of difficult diplomacy. By the early 2010s, several tuna stocks were in serious trouble. Atlantic bluefin had become a marker of overfishing. Pacific bluefin had fallen to […]
New golf-ball sized blue octopus species now identified in the Galapagos
While on a deep-sea expedition in the Galapagos in 2015, scientists found a golf-ball sized, short-armed blue octopus. In a recent study, they confirmed that it’s new to science. The newly described octopus, named Microeledone galapagensis, was first sighted with a remotely operated vehicle (ROV) near an underwater mountain, roughly 1,773 meters (5,800 feet) below […]
Sea cucumber tissue survives for years in open water, study finds
Severed tissue from a cold-water sea cucumber can survive, heal, and even move independently for years in natural seawater, researchers recently found. Some animals have the ability to regenerate tissues and body parts. Certain lizards can regrow their tails, for example. Some sea stars and sea cucumbers, including Psolus fabricii that live in the cold […]
Pilot project in San Francisco Bay aims to help ships avoid gray whales
Starting in 2018, gray whales began regularly stopping in California’s San Francisco Bay, where they are vulnerable to ship strikes in one of the busiest ports in the United States. In response, researchers have deployed a monitoring network of thermal cameras and AI software to alert ships when whales are present in the bay to […]
Canadian government endorses a plan to move whales from shuttered Marineland park to US and Spain
TORONTO (AP) — Canada’s government endorsed a plan Wednesday to move the last remaining captive whales from a shuttered theme park in Ontario to aquariums in the United States and Spain — a plan that could save them from mass euthanasia if the deal goes through. There are 30 belugas and four dolphins left in the Marineland park […]
Offshore wind power cables can affect sensory system of sharks and rays: studies
- A series of studies found that electromagnetic fields from offshore-wind farm cables can trigger various effects in bottom-dwelling sharks and rays depending on species and life stage.
- Experiments on small-spotted catsharks and thornback rays showed behavioral and developmental responses.
- The researchers concluded that electromagnetic fields may increase predation risk during early development by altering natural behaviors linked to predator avoidance.
- eDNA surveys detected multiple shark and ray species inside offshore wind farms, suggesting they may serve as potential refuge areas, though major knowledge gaps remain.

New records of ‘lost’ bamboo shark confirmed in Madagascar
For nearly 20 years, the blue-spotted bamboo shark, found only in Madagascar, went scientifically undetected and unrecorded. But researchers have now found four new records of the “lost” shark while surveying fishing villages and a Malagasy university’s fish collection. These recent records, and interviews with fishers, suggest the species may be more common than previously […]
Scientists warn of climate blind spot as U.S. dismantles ocean sensors
Over the next 15 months, major sensor arrays that have provided crucial, decade-long observations of the ocean, marine ecosystems and climate change will be dismantled. These sensors are part of the Ocean Observatories Initiative (OOI), a $386 million network of more than 900 instruments funded by the U.S. government’s National Science Foundation (NSF), which has […]
Tiny ‘sesame’ sea slug discovered in Taiwan is first of its genus named in 30 years
Researchers have found a new-to-science species of a tiny sea slug with black and yellow spots resembling “scattered sesame seeds.” Measuring just three millimeters long (0.1 inches long), the researchers have named it Thecacera sesama, according to a recent study. Study lead author Ho-Yeung Chan first spotted the sea slug during a recreational dive in […]
France to send its last captive orcas to marine park, not sanctuary
- In May, the French government announced plans to send its last captive cetaceans — two orcas and 12 dolphins — to zoos and entertainment parks in Spain, sparking an outcry from animal welfare advocates.
- France had previously considered sending the marine mammals to an under-construction sanctuary in Canada, but decided to act more quickly because of deteriorating conditions at the shuttered Marineland Antibes park, where the animals are currently housed, according to a French official.
- The dolphins will be shifted to two marine parks in Valencia and Málaga, while the orcas — a mother and son — will be transported to Loro Parque, a zoo and entertainment park in Tenerife, one of Spain’s Canary Islands.
- Animal welfare organizations have criticized the decision, saying they believe the orcas will be used in Loro Parque’s marine shows and bred, which would go against France’s law banning the keeping and breeding of cetaceans for entertainment.

Fisheries and climate research would be hit hard in Trump’s proposed budget
- In April, the Trump administration released its proposed fiscal year 2027 budget for the National Oceanic and Atmospheric Administration (NOAA).
- The proposed budget would slash around $1 billion from the agency, terminate or reduce dozens of programs, and eliminate more than 1,000 positions, with particularly deep cuts aimed at NOAA Fisheries and climate research.
- While the budget proposes many cuts to NOAA’s operations, it also recommends increased financial support for deep-sea mining development, vessel development, and the seafood industry.
- Experts say delayed release of already-approved funding is disrupting research, threatening long-term scientific data sets and hampering fisheries management, species protection and weather and climate monitoring. However, the Office of Management and Budget, which is responsible for dispersing NOAA’s funding, denies there have been delays.

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

Amazon oil drilling plan excludes unique hybrid manatees too big for rescue
- Brazil’s environmental agency approved oil drilling off the mouth of the Amazon River, even though oil company Petrobras considers it “unfeasible” to rescue large animals like manatees in the event of an oil spill.
- Potential oil spills threaten a unique hybrid manatee population perfectly suited to live in the Amazon River mouth area.
- A simulation testing Petrobras’s wildlife rescue plan showed lack of basic supplies and boat accidents.
- The project is part of a massive new oil frontier in the Equatorial Margin estimated to hold 10 billion barrels of oil.

How we tracked China’s deep-sea mining fleet
- In March, Mongabay’s Elizabeth Claire Alberts and CNN International’s Kara Fox co-published an investigation into China’s deep-sea mining fleet’s ambitions and the alleged military dual uses of its oceanographic research ships. This project was supported by the Pulitzer Center, where Alberts was a 2024-2025 Ocean Reporting Network fellow.
- A key finding was that eight Chinese ships involved in deep-sea mining research only spent about 6% of their sea time over the last five years in internationally designated seabed mining areas, while spending the rest of the time elsewhere, including areas identified by Western experts as strategically important for military reasons.
- The investigation illustrates that the nascent deep-sea mining industry not only poses potential environmental risks, but also presents geopolitical implications.
- This article explains how Alberts and Fox worked together to undertake this investigation, which has drawn international attention and was cited or republished by outlets including The New York Times, Inkstick Media and Island Business.

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

Hidden ‘bubble cave’ may help world’s rarest seal steer clear of humans: Study
On the Greek islet of Formicula, researchers have found rare Mediterranean monk seals will take refuge in an air-filled “bubble cave,” according to a recent study. This type of hidden chamber, accessible via underwater passages, allows the seals to breathe, and possibly hide from tourists, the researchers said. Mediterranean monk seals (Monachus monachus), the world’s […]

SONGKHLA LAKE, Thailand — Jampen tends her Yo Yak lift nets and grandkids amid vanishing Luk Bre fish. As pollution threatens this ancestral tradition, villagers join researchers to build fish shelters, map routes with GIS, and innovate processing. Can local wisdom and science revive a fading way of life? Mongabay’s Video Team wants to cover […]
As African cities heat up, a new book argues trees are part of the solution
- Africa’s population is now estimated at nearly 1.5 billion people; the continent is urbanizing faster than any other region in the world and projections suggest that nearly 80% of future population growth will take place in urban areas.
- As the climate continues to warm, scientific evidence shows with high confidence that hot days and nights will become more frequent, while many coastal cities are expected to face increasing flood risks related to rainfall events and sea level rise.
- Across the continent, national authorities, city councils and local governments are increasingly turning to trees and green spaces as part of the solution. But the effectiveness and long-term sustainability of many of these initiatives continue to raise questions.
- A new book documenting 34 case studies from Southern, Eastern, Western and Northern Africa places trees and urban green spaces at the center of efforts to address the continent’s intertwined climate, biodiversity and inequality challenges.

‘World’s deepest banner protest’ launched at the bottom of the sea
Deep below the ocean surface, at roughly the depth of 130 five-story buildings stacked end to end, a robot has unfurled a protest sign that reads: “LISTEN TO THE SCIENCE!” A Greenpeace remotely operated vehicle (ROV) holds the banner more than 2,300 meters (7,500 feet) below the surface of the Norwegian Sea, in front of […]
As economic case for deep-sea mining weakens, industry should halt urgency to begin operation (commentary)
- Deep-sea mining in international waters is a unique proposition, given that the seabed is considered a global commons, so any extraction should be justified for the benefit of all humankind.
- But given the likely environmental and social costs and the increasingly weak economic arguments for it, its proponents must address why there is a supposed urgency to begin commercial production.
- “The financial case for deep-sea mining is being dismantled one argument at a time. As a small number of actors attempt to rush toward seabed mining, it is only a matter of time until more financial institutions join the momentum against [it],” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Risk of saltwater intrusion into coastal groundwater spans the globe: Study
- Coastal sites throughout the world are seeing notable declines in groundwater levels, putting them at risk of saltwater intrusion, according to a new study.
- About half of drinking water and a quarter of irrigation water comes from groundwater, so this trend threatens a vital source of freshwater for humanity.
- The study authors found that more than 10% of monitored locations showed a significant years-long decline in groundwater levels, indicating a susceptibility to saltwater intrusion, which can render water unusable.
- Many large-scale studies on groundwater and saltwater intrusion are model-based, but this one analyzed data from wells across much of the world.

New species of ghost pipefish named after Sesame Street character found in Australia
It’s “hairy,” bright orange or red and “exceptional” at camouflaging. Meet the hairy ghost pipefish, whose recent formal description demonstrates that even well-studied marine environments like the Great Barrier Reef still hold remarkable secrets for science. In a recent study, researchers shared the name of the ghost pipefish, Solenostomus snuffleupagus, for its “conspicuously shaggy appearance,” […]
US prepares to auction leases for seabed mining blocks in federal waters
- The U.S. government is preparing to conduct lease sales to auction off blocks of the seabed for deep-sea mining in federal waters of American Samoa, the Commonwealth of the Northern Mariana Islands, and Alaska.
- If the lease sales proceed, they would mark a major step toward commercial-scale deep-sea mining, making the U.S. one of the first players in the industry.
- While many oppose these plans to start mining the deep sea and say the government’s timeline is rushed, others are more supportive.
- A spokesperson for the U.S. agency managing the sales, the Bureau of Ocean Energy Management, told Mongabay it is pursuing this process in a responsible manner.

Tracking Lucero: Scientists follow a rare Eastern Pacific leatherback sea turtle
Fewer than 1,000 leatherback sea turtles remain in the Eastern Pacific, nesting along the coastline that runs from Mexico to Ecuador. Scientists have previously fitted tracking devices to leatherbacks on other beaches across Latin America and from bycatch near Ecuador. However, they recently tagged the first nesting leatherback in Ecuador, the southern limit of the […]
Iceland must protect wild salmon and reject new aquaculture legislation (commentary)
- Aquaculture and other factors like climate change pose a potentially mortal threat to wild Atlantic salmon, so a new bill in the Icelandic parliament should be rejected, Patagonia founder Yvon Chouinard argues in a new op-ed.
- More than 65% of Icelanders polled agree with him in opposing open-net salmon farming, which the bill would allow to expand despite the fact that it employs a small fraction of those working in the tourism sector, and which relies heavily on the nation’s natural beauty and healthy wildlife populations.
- “Icelandic ministers can listen to reason and citizens and set an example of responsibility, rather than giving in to the worldwide aquaculture industry,” Chouinard writes.

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

The most underfunded climate opportunities may be at sea
- At the Philanthropy Asia Summit’s “Sea Change” panel on ocean-climate solutions in Asia, speakers highlighted a mismatch between the ocean’s importance to the climate transition and the tiny share of philanthropic funding directed to ocean-climate work.
- Ocean philanthropy has long focused on conservation, fisheries, and coastal livelihoods, but climate change is now threatening many of those gains while also making the ocean central to mitigation through offshore wind, cleaner shipping, blue carbon, and coastal resilience.
- Philanthropy cannot finance offshore wind farms or the decarbonization of global shipping, but it can play a catalytic role by funding policy design, marine spatial planning, community engagement, technical research, coordination, and local capacity.
- Some of the strongest opportunities for funders lie in Asia, where offshore wind, ports, shipbuilding, shipping routes, and coastal communities converge, and where early philanthropic support can help make large-scale transitions faster, more inclusive, and more credible.

West Asia conflict brings Norwegian marine research vessel back to Sri Lanka
- The West Asia conflict unexpectedly redirected Norway’s state-of-the-arts Fridtjof Nansen research vessel to Sri Lanka after a planned survey in Oman was disrupted.
- The month-long expedition surveyed Sri Lanka’s marine ecosystems, fish stocks biodiversity and ocean conditions using advanced acoustic and oceanographic methods.
- Scientists documented around 800 species, including about 125 that may be new records from Sri Lankan waters, along with a few species that could be new to science, pending further detailed analysis of the collected specimens.
- The survey revived a previously cancelled mission due to approval delays and offered Sri Lankan researchers some rare hands-on training aboard the United Nations-flagged research vessel.

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

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

Mexico rejects ‘Perfect Day’ waterpark on Caribbean coast, citing environmental risks
Environmental authorities in Mexico have rejected the proposal for a large waterpark in the southern state of Quintana Roo, citing risks for coastal ecosystems and local communities. Royal Caribbean’s Perfect Day Mexico would have covered more than 80 hectares (200 acres) in the village of Mahahual with the “ultimate vacation for families,” including pools, restaurants […]

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

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

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

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

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.

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

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

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

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

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

New Congo oil find highlights Africa’s energy paradox amid Hormuz crisis
On April 13, 2026, TotalEnergies EP Congo announced it had discovered hydrocarbons on the Moho permit, offshore of the Republic of Congo. The company estimates the find could amount to nearly 100 million barrels of recoverable resources, though observers warn that the windfall won’t likely reach many Congolese citizens, roughly a third of whom live […]
Arabian Gulf’s fragile marine ecosystem threatened by current crisis (commentary)
- During the Iran–Iraq war of the 1980s and subsequent conflicts, large-scale oil spills and fires caused lasting environmental damage in the Arabian Gulf.
- A new commentary by United Arab Emirates special envoy of the minister of foreign affairs for nature Razan Khalifa Al Mubarak explains that recovery of impacted marine ecosystems, where it occurred, took decades, but that this progress is now threatened by the new conflict along the gulf.
- “What is at stake today is not only the repetition of past damage, but its amplification across interconnected systems,” she writes in arguing for an end to the current conflict.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

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.

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

The world’s great deltas are sinking — and with them, a global food system
- The Mekong Delta is sinking. Projections indicate that 90% of this life-sustaining landform could disappear by 2100 due to human-driven factors such as groundwater pumping and sediment capture by dams, compounding the effects of sea-level rise.
- The Mekong is just one of 40 of the world’s large river deltas threatened by high subsidence rates coupled with rising sea levels, according to a 2026 global study. Among the 19 river deltas seeing the most significant widespread subsidence are those on the Mekong, Nile, Chao Phraya, Ganga-Brahmaputra, and Mississippi rivers.
- As the world’s great deltas sink, humanity loses rich, irreplaceable agricultural lands, fisheries, urban areas and exceptional biodiversity — much of which will not be salvageable beyond a certain point. Delta loss poses a significant threat to global food security, and an existential threat to often impoverished delta communities.
- Delta subsidence can be slowed and even reversed by implementing well-understood mitigation strategies, say experts, by replacing hydropower dams with alternative energy, reducing sand mining and groundwater extraction, and altering agricultural practices. But these solutions are hampered by economics and lack of political will.

A baby boom for North Atlantic right whales, but extinction still a threat
Calving season for the critically endangered North Atlantic right whale has come to a close with 23 new baby whales, the most calves born in a single year since 2009. Part of the baby boom during the winter calving season can be attributed to females giving birth at closer intervals than in years past: 18 […]
Venezuela tells UN court that mineral-rich part of Guyana was ‘fraudulently’ taken in colonial era
THE HAGUE, Netherlands (AP) — Venezuela insisted Wednesday that a disputed mineral-rich region of Guyana was “fraudulently” taken in a 19th-century example of colonialism, arguing that a 1966 agreement and not the United Nations’ highest court should finalize ownership of the territory. The International Court of Justice is holding a week of hearings between the South American […]
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.

Iceland plans to resume whale hunting this summer
Icelandic commercial whaling company Hvalur hf. plans to resume whale hunting this summer, following a two-year pause in commercial operations. In 2024, the Icelandic government issued the company a five-year license allowing it to catch up to 209 fin whales (Balaenoptera physalus) annually. However, Hvalur hf. didn’t hunt any whales in 2024 or 2025. Iceland’s […]
Endangered whale protections may be delayed to 2035 under Trump-backed plan
PORTLAND, Maine (AP) — For roughly 380 right whales left in the North Atlantic, which can die after getting tangled in fishing ropes or hit by ships, the Trump administration said this month it wants to delay new protections by almost a decade in favor of commercial fishing interests. The sleek black whales, which weigh as much as a […]
With its first marine reserve, Ghana protects its ocean to secure its future (commentary)
- Last month, Ghana made news when it declared its first marine reserve and sited it in one of the nation’s most ecologically and biologically significant marine environments.
- Ghana’s minister for fisheries and aquaculture explains in a new commentary that the Greater Cape Three Points reserve will help restore marine ecosystems and protect the livelihoods of 21 coastal communities, while advancing the nation’s 30×30 conservation goal ahead of next month’s Our Ocean Conference in Kenya.
- “We urge governments everywhere to follow in Ghana’s footsteps to protect more of our ocean, invest in effective management, and ensure communities are at the heart of these efforts,” the minister writes.

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

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

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

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

Saline intrusion in Mekong Delta leaves farmers and scientists at odds
- Vietnam’s Mekong Delta is increasingly facing saltwater intrusion, as sea levels rise, land subsides and the river’s natural cycles are disrupted by dams and irrigation infrastructure.
- A growing scientific consensus says Vietnam must learn to adapt to salt water rather than trying to engineer its way out of the problem; this perspective was officially integrated into Vietnam’s public policy with the 2017 Resolution 120.
- In practice, however, hard infrastructure like sluice gates are popular at the local level and continue to be built.
- Progress implementing Resolution 120 has also slowed due to 2025 administrative reforms that restructured ministries and re-drew provincial boundaries in the delta.

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

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

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

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.

Offshore wind’s clean energy potential remains largely untapped, say experts
- Offshore wind has enormous clean energy potential across the globe. Though the sector has expanded in recent years that potential remains largely untapped.
- Today, China and European nations lead the way in developing offshore wind farms, with the U.S. hampered by the Trump administration, and other nations just beginning to tap into the potential of marine wind.
- Currently, about 80 gigawatts of power is generated by existing marine wind farms. According to some estimates, more than 2,000 GW of offshore wind is needed to meet climate goals, requiring a huge expansion including in deeper waters using floating platforms.

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.

However, she called for transparency about […]
Chile’s plan to protect another 10% of its ocean is stalled by the new government
The expansion of two vast Pacific marine parks near Chile has been suspended for six weeks, leaving protections for around 337,000 square kilometers (130,000 square miles) of ocean in limbo. Former President Gabriel Boric signed a decree creating marine parks Juan Fernández II and Nazca-Desventuradas II on March 10, his last day in office. Together […]
Oil spill continues in Gulf of Mexico vulnerable habitats, while Pemex admits fault
- An oil spill has contaminated 933 kilometers (about 580 miles) of shoreline along the western Gulf of Mexico, impacting the Mexican states of Veracruz, Tamaulipas, Campeche and Tabasco in eastern Mexico.
- After two months of contradictory theories about what could have caused the spill, Mexico’s national oil company, Pemex, admitted the spill was caused by a leak in one of its pipelines.
- Local communities have had to reduce or stop their fishing and ecotourism activities due to a lack of information from authorities about the risks of coming into contact with the water, and despite a government-led cleanup, residents continue to document damages to the environment, such as oil-slicked vegetation and intoxicated or dead fauna.
- Conservationists say the containment of the spill is urgent for the protection of more than 1,000 marine species, among them, endangered Kemp’s ridley sea turtles whose nesting season is underway on the beaches of northern Veracruz and Tamaulipas.

Study finds bottom trawling nets 3,000 marine fish species, including threatened ones
How many marine fish species do bottom trawls catch? Researchers now have a list, and it’s long, running to some 3,000 species, according to a recent study. Bottom trawling is a commercially popular, and controversial, fishing method in which boats drag weighted nets along the seafloor. Usually they target commercially valuable marine life at the […]
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.

Goldman Prize winner Alannah Hurley fights Pebble Mine “from a place of love”
- Alannah Acaq Hurley, executive director of the United Tribes of Bristol Bay, has been awarded the Goldman Environmental Prize for organizing opposition to what would have been the largest open-pit mine in North America, called Pebble Mine.
- Proposed in 2001, Pebble Mine was vetoed in 2023 by the Environmental Protection Agency for posing a major threat to the abundant salmon fishery of Bristol Bay, in southeast Alaska. That veto received additional support this year in court by the Department of Justice.
- In an interview with Mongabay, Hurley discussed the long path she and the United Tribes of Bristol Bay’s coalition have walked to defeat Pebble, as well as the hurdles that remain ahead as the fight moves to court, and as UTBB pursues more comprehensive protections for the Bristol Bay watershed.

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

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

From carp to hippos, 43% of large freshwater animal species spread far beyond native ranges
From fish and turtles, to hippos and crocodiles, about 43% of all known large freshwater animal species have been deliberately introduced into ecosystems outside their native ranges, a recent study finds. Most species were introduced to boost fisheries, food security or tourism, but many have had unintended consequences for local wildlife, habitats and people. Fengzhi […]
San Francisco Bay emerges as high-risk area for migrating gray whales
Gray whales have one of the longest known migrations of any mammal — from the Arctic near Alaska, to the lagoons of Baja Mexico, where they mate and give birth. This annual migration, longer than 19,000 kilometers (12,000 miles), has been altered by climate change, with profound consequences for the 15-meter (50-foot) mammals. Since 2016, […]
Aaron Longton, fisherman who tied sustainability to survival
- Aaron Longton was a commercial fisherman in Port Orford, Oregon, who built his career through persistence and a deep understanding of the marine environment.
- He helped pioneer a model that connected fishermen directly with consumers, improving prices while increasing transparency around how seafood is caught.
- Longton argued that conservation and economic survival were inseparable, supporting science-based management and habitat protection to sustain fisheries over time.
- His work reflected the challenges facing small-boat fishing communities and offered a practical approach to maintaining both livelihoods and fish stocks.

Invasive ferrets removed from an island in a world-first
Rathlin Island off the north of Northern Ireland is now free from feral ferrets that were harming its native seabirds. Conservationists say this is the first time these nonnative animals, which were domesticated from polecats some 2,000 years ago, have been completely eradicated from any island. Ferrets (Mustela furo) were introduced to Rathlin in 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.”
- This article is an analysis. The views expressed are those of the author, not necessarily of Mongabay.

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

Council recommends opening US Pacific marine monuments to commercial fishing
A U.S. fishing regulator recently recommended allowing commercial fishing across all four of the country’s Pacific marine national monuments. The Western Pacific Regional Fishery Management Council (Wespac) said the move is “about restoring sustainable fishing.” Conservationists and native peoples, however, say it will damage some of Earth’s most pristine ocean ecosystems. The monuments — Pacific […]
Tropics take the brunt as hotter oceans drive large-scale humid heat waves: Study
- It’s well known that hotter temperatures due to climate change are dangerous to human health. But when paired with high humidity, this intense heat can be especially deadly. These extreme weather events, known as humid heat waves, are rapidly intensifying and increasing in frequency as the world warms.
- A recent study found a strong causal link between hotter coastal ocean temperatures and large-scale humid heat waves. Rising sea surface temperatures are driving 50-64% of the increase in large-scale humid heat waves, researchers found, especially in the tropics, and raising the risk of heat-related fatalities.
- These events do not remain localized. The researchers found that coastal humid heat waves can move far inland, and have a 90% chance of occurring even 1,000 kilometers (620 miles) away from where they originated over the ocean.
- Humid heat waves now pose a serious risk to people in tropical regions, though such events are forecast to worsen in temperate zones too as the world warms. Adding to threats in the tropics is insufficient air-conditioning to safeguard populations against such events. Humid heat waves also make outdoor work unsafe, impacting local economies.

Half of seabirds are declining. Protecting marine flyways could help save them
- Nearly half of migratory seabird species are in decline, in part because conservation systems stop at borders while the birds do not.
- A new study maps six “marine flyways” spanning the world’s oceans, showing how 151 species depend on connected routes across dozens of countries.
- These pathways link breeding sites, feeding areas, and migration corridors, but face persistent threats from bycatch, invasive species, and climate change.
- Coordinating protection along these routes—rather than focusing only on isolated sites—could improve conservation outcomes for seabirds at a global scale.

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.

24 new species found in ocean zone eyed for battery metals mining
- Scientists discovered 24 new species of tiny crustaceans and an entirely new evolutionary branch from a deep abyss in the central Pacific, some 4,000 meters below the surface.
- The the Clarion-Clipperton Zone (CCZ) is studded with chunks of fused nickel, cobalt, copper and other minerals, making it one of the most commercially coveted tracts of ocean on Earth.
- An estimated 90% of species in the Clarion-Clipperton Zone remain unnamed even as the U.S. moves to streamline the permitting process to mine the seabed for critical minerals.
- A 2025 study found that a commercial mining test in the zone reduced animal abundance by 37% within the machine’s tracks, highlighting the ecological cost of extraction in a region science is only beginning to understand.

EU citizens file complaint for delays in response to anti-shark fin campaign
The organizers of a campaign against shark finning in the European Union have filed a formal complaint against the EU Commission, accusing it of mishandling their case and missing deadlines. The European Citizens’ Initiative (ECI) is an EU tool that allow citizens to participate in policy-making. The ECI known as “Stop Finning – Stop the […]
Malawi says there’s been no illegal crayfish smuggling for a year
Authorities in Malawi have credited stronger monitoring and border controls with effectively ending the smuggling of invasive crayfish into the country, nearly a year after a major seizure from neighboring Zambia. Davie Khumbanyiwa, the fisheries department officer responsible for monitoring, control and surveillance, said the department has increased inspections for redclaw crayfish (Cherax quadricarinatus), a […]
Migratory species summit adopts new marine protections amid extinction warnings
- Delegates to the latest meeting of the Convention on Migratory Species of Wild Animals adopted new protections for 40 migratory species, including 33 marine animals like sharks, seabirds and shorebirds.
- The convention’s 15th Conference of the Parties (COP15), held in Brazil March 23-29, recognized the importance of “marine flyways” for migratory birds and highlighted key marine biodiversity areas.
- It also urged protection of seamounts from destructive fishing practices and a precautionary approach on deep-sea mining to address potential impacts on migratory species.
- Conservation advocates lauded the steps taken at COP15, but the summit also issued stark warnings that extinction and species decline are accelerating.

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

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.

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