No respite for Indonesia’s Raja Ampat as nickel companies sue to revive mines
- Three companies are suing the Indonesian government to be allowed to mine for nickel in the Raja Ampat archipelago, a marine biodiversity hotspot, Greenpeace has revealed.
- The finding comes after the government’s recent revocation of four other mining permits in the area, following a public outcry over environmental damage and potential zoning violations.
- At the same time, the government is also encouraging the development of a nickel processing plant nearby, raising concerns this could fuel pressure to reopen canceled mines to supply the smelter.
- Greenpeace has called for a total mining ban across Raja Ampat and for an end to the smelter project to ensure the conservation of the archipelago’s unique ecosystems and biodiversity.

If implemented as envisioned, the reserve would become the world’s first Indigenous-led ocean reserve, covering an area nearly as big as the Amazon Rainforest. Speaking at the U.N. Ocean Conference underway in Nice, France, representatives […]
‘It’s our garden’: PNG villages fight to prevent mine waste dumping in the sea
- Communities in Papua New Guinea filed a lawsuit asking for a review of an environmental permit awarded in 2020 to companies for the Wafi-Golpu copper and gold mine. But a decision from the country’s Supreme Court had been delayed several times, before happening on June 12, even as other officials have signaled the government’s apparent support for the project.
- The villages are located near the outflow of a proposed pipeline that would carry mining waste, or tailings, from the mine and into the Huon Gulf.
- The companies say the method, known as deep-sea tailings placement (DSTP), would release the waste deep in the water column, below the layer of ocean most important for the fish and other sea life on which many of the Huon Gulf’s people rely.
- But community members are concerned this sediment and the potentially toxic chemicals it carries could foul the gulf — risks they say they were not adequately informed of.

Speaking on the first day of the United Nations Ocean Conference in France, French Polynesian President Moetai Brotherson said the MPA will cover the territory’s entire exclusive economic zone (EEZ), or 4.8 million square kilometers (roughly 1.9 million square miles). “We have […]
‘Madness’: World leaders call for deep-sea mining moratorium at UN ocean summit
- World leaders have renewed calls for a global moratorium on deep-sea mining at the 2025 U.N. Ocean Conference (UNOC) in Nice, France, as the U.S. moves to mine the deep sea in international waters under its own controversial authority.
- Four additional countries have joined the coalition of nations calling for a moratorium, precautionary pause, or ban on deep-sea mining, bringing the total number to 37.
- The U.S., which did not have an official delegation at UNOC, is pushing forward with its plans to mine in international waters — a decision that has drawn criticism from the international community.

New study dismisses Amazon River runoff as primary cause of sargassum blooms
- Brazil’s northern beaches recently suffered from arrivals of sargassum blooms, a phenomenon affecting Caribbean nations that most scientists so far have associated with nutrients coming from the Amazon River plume into the Atlantic Ocean.
- A recent study suggests that ocean changes are the primary nutrient source for sargassum blooms since 2011, challenging previous hypotheses.
- Sargassum is causing considerable health and economic concerns as large amounts of this brown macroalgae arrive and accumulate in coastal ecosystems of western Africa and the greater Caribbean Sea every year.
- Brazilian authorities are learning from Caribbean countries how to manage sargassum blooms best, and experts think they should keep monitoring possible ocean current changes.

Stars & lighthouses: Marine conservation that blends Pacific Islander wisdom and Western knowledge (commentary)
- The U.N. Ocean Conference this week is tackling a range of issues, such as how to conserve and sustainably use the oceans and marine resources: a new op-ed argues that the strength of Indigenous islander conservation practices lies in their flexibility and adaptability, while Western conservation efforts bring clear, formal, and intentional goals — and that blending the two can return inspiring results.
- “Conservation is not just about the number of lighthouses we build — about visible policies and formal designations — but we must also name and recognize the stars that have guided us all along; the quiet, steadfast traditions that have protected our oceans for thousands of years,” the author writes.

Indonesian women sustain seaweed traditions in a changing climate
- The women of Indonesia’s Nusa Penida and Nusa Lembongan islands have harvested seaweed for generations.
- Climate change and tourism development now threaten seaweed cultivators’ centuries-old practices.
- In the face of these changes, seaweed cultivators are working with tourism operators and coral-conservation groups to preserve, and adapt, their traditional practices.

Indonesia halts most nickel mining in Raja Ampat, but allows one controversial permit
- Indonesia has revoked four out of five nickel mining permits in Raja Ampat after public pressure and findings of environmental damage in the ecologically sensitive archipelago, home to some of the world’s richest marine biodiversity.
- However, the government retained the permit for PT Gag Nikel, citing its location outside a UNESCO-designated geopark, lack of visible pollution, ongoing land rehabilitation, and the high economic value of its nickel deposits.
- Environmental groups have criticized the decision, pointing to legal bans on mining on small islands and warning of threats to marine life such as manta rays and coral reefs from barge traffic and industrial activity.
- The case reflects broader concerns about Indonesia’s nickel rush, with nearly 200 mining concessions on small islands nationwide, raising alarms over environmental destruction and the prioritization of industry over legal and ecological safeguards.

When our oceans can’t breathe, a sea change is needed (commentary)
- “Even if we can’t see it, the ocean is telling us it can’t breathe. It’s time to listen and to act,” a new op-ed argues as global leaders and changemakers gather for the U.N. Oceans Conference this week.
- When oxygen levels in parts of the ocean drop dangerously low due to land-based pollution, hypoxic “dead zones” where marine life can no longer thrive are the result, driving ecosystem and fisheries collapses.
- These zones have grown by an area the size of the European Union over the past 50 years, but the Global Environment Facility’s Clean and Healthy Ocean Integrated Program is aimed at tackling this overlooked yet expanding threat.

One-two punch for mangroves as seas rise and cyclones intensify
- More than half of mangroves worldwide may face high or severe risk by 2100 due to increased tropical cyclones and sea level rise, with experts predicting Southeast Asia to be hardest hit under all emissions scenarios.
- A new risk index combines multiple climate stressors — cyclones and sea level rise — with ecosystem service value, providing a novel, globally scalable tool for risk assessment and conservation planning.
- Mangrove loss has major human and economic costs, jeopardizing flood protection worth $65 billion annually and threatening 775 million people dependent on coastal ecosystems.
- Urgent, dynamic conservation and emissions cuts are essential; restoring degraded areas, enabling inland migration, and reducing emissions could significantly reduce risk and buy adaptation time.

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

World Oceans Day: Scientists find new clues about frontiers of ocean life
Humpback whales in Western Australia. Image courtesy of Emilie Ledwidge/Ocean Image Bank.In 2008, the United Nations recognized June 8 as World Oceans Day to spotlight the rising vulnerabilities facing the oceans that cover more than 70% of Earth’s surface. Seventeen years later, average ocean temperatures have never been higher. Heat stress has hit 84% of the world’s coral reefs. In places as far as Antarctica, whales […]
Researchers race to understand disease killing Caribbean corals at unprecedented rates
- Stony coral tissue loss disease (SCTLD) is a novel coral disease that first emerged in Florida in 2014, and has now spread to 33 countries and territories in the Caribbean, including along the Mesoamerican Reef.
- SCTLD affects an unprecedented number of species (more than 30 species of reef-building corals), spreads quickly, and has a very high mortality rate.
- Researchers are still trying to figure out exactly what causes the disease.
- Researchers are also trying to understand how the coral microbiome is involved in or responds to SCTLD infection, and developing probiotics that they hope will offer an alternative treatment to antibiotics, with fieldwork in Belize, Colombia and elsewhere.

New method can detect nearly every coral genus in Japan from water samples
- Environmental DNA (eDNA) coral research involves analyzing water samples to identify corals based on the DNA that they secrete into the water, largely via their mucus.
- eDNA research on corals can help scientists understand the changes wrought by global warming and marine pollution by providing coral identification data faster and in some cases more accurately than visual surveys by scientists.
- A team of marine scientists based in Japan, an archipelagic nation with a high level of coral biodiversity, has used an eDNA method to develop a system that can detect nearly all of the country’s 85 reef-building coral genera; no other research group in the world has achieved the same level of detection accuracy and coverage for corals using eDNA.
- They released their findings in a study published on May 22.

Pay-to-release program reduces shark deaths, but backfires in some cases
- A pay-to-release program for threatened sharks and rays significantly reduced bycatch in Indonesia, with 71% of wedgefish and 4% of hammerheads released alive; but it also led some fishers to intentionally catch these species to claim incentives.
- Unequal payments across regions (ranging from $1 to $135 per fish) and the absence of national protective laws have complicated conservation efforts in key fishing areas like East Lombok and Aceh Jaya.
- A rigorous randomized controlled trial revealed unintended consequences: wedgefish mortality dropped by just 25%, while hammerhead mortality rose by 44% due to incentive-driven targeting.
- Local NGO KUL, which runs the program, has revised it to limit payouts and promote gear swaps, aiming to better align conservation outcomes with fisher livelihoods in the world’s top shark- and ray-catching nation.

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

Marine artificial upwelling, problematic climate solution slow to advance
- Artificial upwelling is a form of geoengineering that aims to use pipes and pumps to channel cool, nutrient-rich water from the deep ocean to the surface. In doing so, it could fertilize surface waters, prompting the growth of plankton, which can then absorb and store large amounts of atmospheric carbon.
- Long considered a potential marine carbon dioxide removal (CDR) method, artificial upwelling has more recently been coupled with seaweed farming to potentially soak up even more atmospheric CO2.
- But technological challenges have plagued open-water upwelling experiments, while environmentalists worry that large-scale use could ultimately prove ineffective and ecologically harmful.
- Experts state that though upwelling could prove a viable solution to improve fisheries and protect coral reefs from marine heat waves, more research is needed. Considering the rapid current pace of climate change, it’s debatable as to whether implementation at scale could come in time to stave off dangerous warming.

From local planting to national plan, Belize bets on mangrove recovery
- Mangroves in Belize protect coastlines, are nursery grounds for fish, and store vast amounts of carbon.
- In 2021, the government of Belize committed to restoring 4,000 hectares (nearly 10,000 acres) of mangroves, and protecting an additional 12,000 hectares (nearly 30,000 acres) within a decade, as part of its emissions reduction target under the Paris climate agreement.
- To support this restoration target, WWF Mesoamerica is developing a national mangrove restoration action plan.
- Restoration initiatives are already underway in areas like Gales Point, Placencia Caye and elsewhere.

US pioneers restoration of deep water corals damaged by country’s worst oil spill
- Scientists are conducting a pioneering large-scale deep-sea coral restoration in the Gulf of Mexico following the 2010 Deepwater Horizon oil spill, which damaged 1,994 square kilometers (770 square miles) of seafloor habitat.
- Underwater robots and Navy divers using specialized gear to work at depths up to 100 meters (328 feet) plant coral fragments on the ocean floor, while labs in Texas, South Carolina and Florida grow corals in tanks for future transplantation.
- The novel eight-year, multi-million-dollar project has achieved milestones including high deepwater coral survival rates at sea and the first successful spawning of deep-sea corals in captivity, which produced more than 1,000 baby corals.
- The restoration faces ongoing threats from climate change, commercial fishing, agricultural runoff and potential future oil spills, with nearly 1,000 spills occurring in U.S. waters in 2021 and 2022 alone.

Only a tiny % of the deep seafloor has ever been visually observed: Study
- Just 0.001% of the deep seafloor has ever been captured by photo or video images, a new study finds.
- That which has been captured is “biased” and potentially unrepresentative: 65% of observations have been in the waters of the United States, Japan or New Zealand, according to the study.
- Experts told Mongabay that policymakers at a wide range of international institutions should bear the study’s findings in mind, including those governing high seas fisheries, deep-sea mining, and the use of marine carbon dioxide sequestration systems.

Mining companies use legal loopholes to move forward without environmental licensing off the Brazilian coast
- Applications for deep-sea mining permits in Brazil have soared in recent years: of the 950 requests filed since 1967, nearly half were submitted between 2020 and 2024.
- Demand for key minerals used in the clean energy transition, as well as geopolitical uncertainties, are driving the race to the seabed.
- Loopholes in Brazilian legislation are allowing mining companies to work without environmental licensing, a situation made worse by the lack of specific rules for deep-sea mining.
- Researchers warn that the lack of environmental impact studies could have widespread impacts on marine ecosystems, especially on coral reef biodiversity.

New map highlights complex web of marine migrations
- Scientists have launched a new database on marine migratory patterns to address gaps in the knowledge of policymakers and conservationists.
- The Migratory Connectivity in the Ocean (MiCO) database pulled data from 1,300 existing studies in the scientific literature to describe the migratory patterns of 109 mammal, bird and fish species.
- The database highlights the interconnected nature of marine migrations, and underscores the need for cross-border collaboration in conservation efforts.

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

Coral reef research dominated by rich countries, plagued with inequities: Study
- A new study finds that coral reef researchers come mainly from institutions in high-income countries, and that the contributions of researchers from tropical, lower-income nations aren’t adequately recognized.
- “Parachute” research that leaves out local input is common, and when more local researchers are included, they report that it’s often done in a tokenistic way, the study finds.
- The lead authors say the same communities that face the most direct impacts from the demise of coral reefs are left out of the scientific study of reefs.

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

Climate change now threatens thousands of species on Earth
- A new analysis of more than 70,000 wild animal species reveals that climate change now threatens thousands of to the planet’s wildlife, along with overexploitation and habitat degradation.
- The study found that nearly 5% of the assessed species are threatened by climate change, with ocean invertebrates being particularly vulnerable to climate change-related threats, such as extreme temperatures, floods, droughts, storms and ocean acidification.
- The study warns that some animal populations, both on land and at sea, have already begun to collapse due to climate change-related events, and it’s now necessary to monitor mass die-offs to understand the impacts of climate change and predict future impacts.

The Great Whale Conveyor Belt (cartoon)
While migrating between their feeding and mating grounds, baleen whales transport massive amounts of nutrients across latitudes. This phenomenon is termed “The Great Whale Conveyor Belt”, prompting scientists to argue that whale conservation can help improve the resilience of global marine ecosystems.
Cruise ships and intensified tourism in Mexico threaten whale shark habitat
- In Baja California Sur, Mexico, a private tourism company, Aquamayan Adventures, and the port administration have reached an agreement that allows mega cruise ships to enter Bahía de La Paz. Environmental organizations are urging the government to cancel the agreement.
- The agreement allows at least 150,000 annual visitors, a figure four times that of cruise passengers received in 2023 and equivalent to 60% of the resident population of the city of La Paz, the state’s capital.
- In addition, the company intends to build a large tourism and commercial complex that could have serious environmental, social and economic impacts on the city and surrounding area, according to organizations concerned about the project.
- Bahía de La Paz is a critical location for marine species like the whale shark, which was affected by the presence of a high number of mega cruise ships in 2020, and which could now be the victim of collisions with vessels arriving to port.

Angling for answers, this saltwater fishing group boosts research for better conservation
- Though anglers aren’t generally thought of as environmentalists, many people who fish are conservation minded, whether because it’s an outdoor pursuit, or because they wish to ensure future harvests.
- Whatever their reasons, there aren’t many groups that help anglers advocate for sustainable fishing regulations based on solid science, nor ones that also work to generate new data that helps them argue for better conservation.
- “Until we came along, there was no voice for those saltwater anglers who cared about conservation, but didn’t have enough time to put into it to really understand it,” says American Saltwater Guides Association vice president Tony Friedrich.
- His team not only helps its members articulate the need for conservation and regulation, they actively participate in developing data that helps managers set better limits, through projects like their GotOne App.

European body proposes mass killing of cormorants to protect fish stocks

The proposal […]
There’s something fishy about ‘blue economy’ proposals for sustainable marine management (commentary)
- Proposals for developing a “blue economy” emerged in the 2010s as a vision for sustainable ocean development, as communities across the world grappled with challenges of declining ocean health, economic crises and stalling development outcomes.
- Central to their appeal is a promise to transform human interactions with the ocean, promoting a shift toward ecological health, improved livelihoods and job creation, but too often these proposals have been driven by large nations and interests, rather than small coastal nations whose prosperity is most heavily linked with marine ecosystems.
- The author of this commentary warns that this sustainable ocean vision may be operating as a tool for pacifying demands for sustainable and equitable ocean relations, rather than as one that advances them.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Annual ocean conference nets $9.1 billion for initiatives, despite US absence
- The 10th annual Our Ocean Conference took place in Busan, South Korea, April 28-30.
- Delegates announced 277 new commitments totaling around $9.1 billion for initiatives across the conference’s six main target areas: the ocean-climate nexus, marine pollution, MPAs, sustainable fisheries, the blue economy and maritime security.
- Notable commitments at this year’s conference included Panama moving to increase fisheries transparency, $6 billion in funding for blue economy initiatives and more pledges to ratify the high seas treaty.
- This marked the first OOC without delegates or financial pledges from the U.S. government, which initiated the conference in 2014.

A Honduran reef stumps conservationists with its unlikely resilience
- The latest “report card” on Mesoamerica’s coral reefs made clear that 2024’s hottest-ever recorded summer temperatures devastated some of the region’s most iconic reef sites.
- But against all odds, a reef in Tela Bay on Honduras’s Caribbean coast, composed largely of critically endangered elkhorn corals (Acorpora palmata), displays remarkable health.
- Known affectionately as “Cocalito,” this patch of coral is raising urgent questions about what qualities endow coral with heat resilience and whether they can be harnessed to help save other reefs.

Blue whale decline in Sri Lanka tied to climate and human activity
- A resident population of blue whales has for many years lived in the coastal waters of Sri Lanka, but in recent years sightings of the animals have declined rapidly.
- With multiple pressures on these massive creatures — from ship traffic on one of the world’s busiest shipping lanes, to disturbance from whale tourism, pollution and surface sea temperature rise and climate change — there are several possible factors for the disappearance of the whales.
- Sri Lanka’s leading marine researchers agree that increasing sea temperatures in the North Indian Ocean, warming at the fastest rate of any of the world’s oceans, have likely pushed the whales to new waters.

Scientists warn coral restoration can’t keep pace with global reef collapse
- Coral restoration is vastly outpaced by degradation, while intensifying climate stress, prohibitive costs, poor site selection and lack of coordination make large-scale restoration currently unviable, a new study has found.
- The scale-cost mismatch is staggering: Restoring just 1.4% of degraded coral could cost up to US$16.7 trillion, while current global funding is only US$258 million.
- The study found most projects assessed prioritize convenience over ecological value, restoring easily accessed reefs instead of climate-resilient or biologically strategic ones, undermining long-term outcomes.
- Researchers say standardized data and smarter planning are urgently needed to ensure that global coral restoration is scientifically informed and strategically targeted, and not merely symbolic.

‘We belong to one ocean’: Indigenous leaders push for seat at the table of high seas biodiversity treaty
- Members of Indigenous peoples and coastal communities convened at the United Nations Permanent Forum on Indigenous Issues to call for their inclusion in the Agreement on Marine Biodiversity of Areas Beyond National Jurisdiction (BBNJ), also known as the High Seas Treaty.
- These are the first-ever calls by Indigenous and coastal communities as members attending the forum prepare for the entry into force of the BBNJ agreement.
- Their participation could include involvement in governance, environmental management, and best-practice strategies based on traditional ecological knowledge and values.
- The BBNJ agreement will enter into force once at least 60 countries ratify it. So far, 113 countries have signed the agreement, while 19 have ratified the treaty.

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

Global offshore oil platforms are among top ocean polluters, report finds
Most new oil and gas projects in 2024 were located offshore, where spills can be hard to detect.

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

Whales and dolphins at risk as report reveals ecological decline in Gulf of California
- The recent “Assessment of the Ecological Health of the Gulf of California” report shows a decline in several populations of animals throughout the narrow sea flanked by the Mexican mainland and Baja California.
- The report was compiled by the Next Generation Sonoran Desert Researchers (N-Gen) in the U.S. in collaboration with Prescott College’s Kino Bay Center field station in Mexico, and draws on long-term monitoring studies.
- Many of the assessed groups, such as seabirds, whales, giant squid, crabs, starfish and fish, are in decline.
- Basic primary productivity, which nurtures species diversity and abundance in the Gulf of California, remains stable.

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

With deep-sea mining plans in limbo, Norwegian companies fold or dig in
- Norway’s plans to mine seabed minerals in Arctic waters remain in limbo after the first licensing round was delayed in December 2024. However, the government maintains that progress will resume soon, with a licensing round tentatively set for 2026.
- Some deep-sea mining companies have faced significant financial struggles due to the delay, with one company going bankrupt and another slashing costs; yet, other firms remain optimistic, insisting the industry’s future is still secure.
- Experts warn that considerable knowledge gaps must be addressed before deep-sea mining can proceed, particularly regarding environmental impacts.
- In Norway, the industry also continues to face heavy opposition from environmental groups, the fishing sector, and several political parties.

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

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

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

Even the Gulf of Aqaba’s ‘supercorals’ bleached during 2024 heat wave
- Scientists have long considered the corals in the Gulf of Aqaba in the northern Red Sea to be uniquely resilient to extreme temperatures.
- For the first time on record, however, the heat wave of 2024 bleached some of these super-resilient corals in Israeli and Jordanian waters, according to scientists.
- Scientists studying the episode’s severity and extent estimate that perhaps 5% of the corals in their study area in Israeli waters bleached during the oppressive Northern Hemisphere summer; a small fraction died, but most recovered over the relatively cooler months that followed.
- Tackling threats like pollution that could reduce the corals’ ability to withstand extreme heat is the best way to protect them from rising marine temperatures, and scientists say an oil terminal that sits barely half a kilometer from some of the “supercorals” poses an imminent threat.

Award-winning film highlights lasting damage from X-Press Pearl disaster in Sri Lanka
- “This Is Not a Pearl,” a short film by Sri Lankan filmmaker Tharindu Ramanayaka, uses a poetic narrative of a pearl oyster mistaking toxic plastic pellets, or nurdles, for her pearl to symbolize the environmental devastation caused by the 2021 MV X-Press Pearl disaster.
- The sinking of the MV X-Press Pearl off Sri Lanka’s coast released 1,680 metric tons of plastic nurdles, marking the world’s largest nurdle spill and triggering long-term damage to marine ecosystems.
- Scientific studies show that toxic chemicals from the spill continue to harm marine life, especially zooplankton like sea urchin larvae and copepods, threatening the broader ocean food web.
- Sri Lanka’s legal efforts for compensation, including cases in both Singapore, where the ship’s operator is based, and the Sri Lankan Supreme Court, remain unresolved; meanwhile, nurdles continue to wash ashore, requiring continuous cleanup efforts nearly four years later.

Melting Antarctic ice could weaken world’s strongest ocean current, study warns
Scientists on a British Antarctic Survey ship measure the conditions of the ACC. Image courtesy of Michael Meredith.The strongest ocean current on Earth circles Antarctica. It’s the primary way water moves between the Atlantic, Pacific and Indian oceans, and helps regulate the global climate. But a new study suggests the Antarctic Circumpolar Current (ACC), which until now has been extremely stable, might begin to slow down in the next 25 years, with […]
Bangladesh witnesses coastal erosion, salinization as tourism crushes a flowering creeper
- Bangladesh’s sandy beaches have been witnessing the disappearance of a once-common flowering vine, the beach morning glory, especially on Cox’s Bazar beach.
- Seashore erosion is now increasing in the region as this plant is supposed to retain soil and protect the beach from erosion.
- Experts and studies indicate the excessive and unchecked tourism in the coastal district as one of the major reasons for this loss.

Study delves into increase in humpback whale sightings in UK and Ireland

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

‘Substantial’ transshipment reforms adopted at North Pacific fisheries summit
- The annual meeting of the North Pacific Fisheries Commission (NPFC), a multilateral body that manages most non-tuna fisheries in the region’s international waters, was held March 24-27 in Osaka, Japan.
- In a bid to deter illegal fishing, the NPFC’s nine members agreed to require independent observers on ships that transfer fish at sea.
- The parties agreed to study the impact of bottom fishing on ocean habitats and to protect two small areas on one seamount. They also increased transparency in the NPFC compliance process and reduced the total allowable catch for two key pelagic species.

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

Community-based conservation cuts thresher shark fishing by 91% in Indonesia: Study
- A conservation effort in eastern Indonesia helped reduce thresher shark catches by 91% among participating fishers by providing alternative income opportunities, according to a recent study.
- The program, which ran from 2021 to 2023, supported nine voluntary fishers with resources to transition to new livelihoods, leading to increased income for some, though a few struggled due to personal challenges and job instability.
- However, some fishers felt pressured by family or community expectations to continue shark fishing, and conflicts with local leaders also influenced participation.
- The study highlights the need for long-term conservation efforts that involve local communities, address socio-political challenges and receive strong government support.

Locals debunk myths linking endangered pink river dolphins to ‘love perfumes’
Why is this endangered dolphin being killed to make "love perfumes"?A colonial-era myth about endangered pink river dolphins in the Amazon has led to a false belief that perfumes or pusangas made from their body parts are potent love potions. According to a recent Mongabay documentary, the myth has created a market for the perfumes, further endangering the dolphins. The film, released in February, follows […]

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

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

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

‘Fatal Watch’: Interview with documentary makers on fisheries observer deaths
- A new documentary, “Fatal Watch,” shows the dangers of work as a fisheries observer, a job that involves collecting scientific data aboard industrial fishing vessels and documenting compliance with conservation and other rules.
- The film focuses on four cases in which fisheries observers died or disappeared on the job during the last decade.
- “Fatal Watch” also casts a critical eye on the fishing industry as a whole, touching on management and transparency issues that the filmmakers see as intertwined with the observer safety problem.
- The film will premiere in California on March 21 at the Sonoma International Film Festival and play in Washington, D.C., on March 24 at the DC Environmental Film Festival, where Mongabay is a media partner.

Seal ‘oceanographers’ reveal fish abundance in Pacific Ocean’s twilight zone
- The open ocean’s twilight zone, a vast deep ecosystem rich in fish biomass, is poorly understood because it is expensive and challenging for humans to reach its depths 200–1000 meters (660–3,280 feet) below the surface.
- A new study used northern elephant seals (Mirounga angustirostris) — marine predators that forage in the twilight zone — to help understand fish abundance deep down, both five decades into the past and two years into the future.
- The findings illustrate how apex marine predators, such as elephant seals, can serve as sentinels in understanding how fish abundance cascades through marine food webs.
- Given increased interest in fishing in the twilight zone and the unfolding effects of climate change, seals and other deep-diving marine predators could help keep an eye on changes in the oceans’ depths.

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

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

A bird last seen by Darwin 190 years ago reappears on a Galápagos island
The Galápagos rail, a small, black, ground bird, hadn’t been seen on Floreana Island in the Galápagos since 1835, when Charles Darwin first described it. That changed recently when researchers monitoring birds on Floreana recorded the rail at three different locations. These new sightings after 190 years are likely the result of efforts to eradicate […]

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

New Zealand blocks tighter trawling rules at South Pacific fisheries meeting
- The South Pacific Regional Fisheries Management Organisation (SPRFMO), a multilateral body that regulates fishing in the vast waters of the South Pacific Ocean, held its annual meeting Feb. 17-21 in Santiago, Chile.
- At the meeting, Aotearoa New Zealand blocked an effort to implement a rule that would reduce bottom trawling, a fishing practice that disrupts the seabed, in areas occupied by vulnerable marine ecosystems.
- Conservationists lambasted New Zealand’s move, while a New Zealand official defended the country’s approach.
- In other meeting news, the parties raised the fishing quota for jack mackerel above scientifically advised limits and, at the same time, moved forward toward adopting a harvest strategy for the stock that could prevent such abrupt quota hikes in the future.

Funerary practices in Fiji protect marine areas while honoring the deceased
- Indigenous (iTaukei) people across Fiji have historically protected their freshwater and marine areas in memory of chiefs and community members who have passed away. These are called aquatic funerary protected areas (FPAs).
- Researchers published a study to shine a light on this sustainable resource management practice, which they say could present a community marine conservation solution in the region but is largely absent from scientific literature and rarely implemented as a strategy.
- FPAs differ in size and practice but can stretch from shoreline to fringing reefs and tend to ban fishing and harvesting of many species for 100 nights after they are declared.
- From 1960 to 2019, communities established a total of 188 FPAs where 44% of FPAs were protected for 100 nights, and 47% protected all resources and associated ecosystems form fishing and harvesting.

Concerns of illegal sea turtle trade persist in Bali as police foil smugglers
- Seizures of large consignments of live turtles in northwest Bali in January have raised concerns among conservationists that trade in the protected species may remain pervasive despite recent progress by civil society and law enforcement.
- Six of the world’s seven species of sea turtle live in the waters around Indonesia, the world’s largest archipelago country.
- WWF Indonesia said the scale of the seizures in January indicated that the trade may be to supply turtle meat for consumption, rather than just for Hindu ceremonial uses.
- A 2019 investigation found authorities in Indonesia, Malaysia and Vietnam seized at least 2,354 whole turtles and more than 91,000 eggs from 163 law enforcement operations between 2015 and July 2019.

The U.S. terminated its 30×30 conservation plan but this also presents an opportunity (commentary)
- “We should be proud of the progress that was made over the last years, but conservation priorities have always evolved [to] save the whales, save the rainforest, to today’s focus on climate change and area targets,” and the recent U.S. withdrawal from the global 30×30 conservation initiative won’t change that, a new op-ed argues.
- The U.S.’s 30×30 goal was central to President Biden’s America the Beautiful for All initiative and mobilized federal funding, new protections, and an all-of-government approach to conservation.
- “We should not accept these rollbacks as permanent defeat,” the authors say, but rather as “an opportunity to make our efforts sharper and more effective.” The loss of 30×30 should not be seen as a rejection of conservation values, but as a call to reimagine a conservation strategy that works for more people in more places.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

Baja California tourism poses mounting challenges for conservation, critics say
- Baja California Sur attracts more foreign tourism investment than any other state in Mexico, but the rapid development also poses threats to protected areas, marine habitats and the traditional customs of small communities.
- Numerous hotel projects underway this year could level sand dunes and encroach on protected areas, overwhelming many environmental activists who aren’t sure how to combat the rapid development.
- Some critics question the eco-tourism model that has been applied to coastal fishing villages, many of which regret trading in their customs for tourist businesses.

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

Conservation groups look for new strategies, tech to halt vaquita decline
- Experts believe fewer than 10 vaquita, the world’s smallest porpoise, survive in Mexico’s Gulf of California, also known as the Sea of Cortez, the only place the species lives.
- Illegal fishing has decimated their population, forcing environmental groups to come up with innovative conservation solutions.
- Vaquitas get caught in illegal gillnets that fishermen use to target totoaba, a fish whose swim bladder can go for tens of thousands of dollars per kilo on the international black market.
- Some environmental groups have focused on patrolling vaquita habitats with ships, sonar, radar and drones, while others maintain that dismantling the organized crime groups behind the totoaba trade is a better use of resources.

How a Philippine town is dealing with the fallout of its own popularity

Order restored in Indonesia as fishers recapture scores of farmed crocodiles
- On Jan. 13, several hours of extreme rain over Indonesia’s Batam archipelago, a one-hour ferry from Singapore, caused a breach in the perimeter of a large saltwater crocodile (Crocodylus porosus) farm on the east of Bulan Island.
- More than 100 of the stir-crazy predators reportedly escaped in the storm, causing panic among the population while halting local fishing activities.
- Elected representatives in Batam have since called for the farm to be closed, citing tax irregularities.
- The global supply of reptile skins remains concentrated in northern Australia for the fashion industry, which claims to operate high animal welfare standards despite allegations of extensive suffering on farms.

Lawsuit is latest push to curb bottom trawling in protected European waters
- The fishing practice of bottom trawling continues in European marine protected areas (MPAs) despite conservation concerns over its destruction of seabed habitats and indiscriminate catches.
- Four NGOs have sued the Netherlands to stop bottom trawling in the Dutch section of Dogger Bank, an MPA in the North Sea, citing its ecological importance.
- Advocacy efforts across Europe, including other lawsuits, have led to some restrictions on the practice, such as the closure of the U.K. section of Dogger Bank to bottom trawling, but most European MPAs remain insufficiently protected, a 2024 study indicates.
- Fishing interests often disagree with the NGOs’ position on bottom trawling in MPAs, saying that regulated bottom trawling can coexist with conservation goals and support communities socioeconomically, and that blanket restrictions risk marginalizing fishing communities without addressing broader environmental challenges like pollution or climate change.

Mass salmon deaths hit Scottish farms as government investigates
- Hundreds of thousands of Atlantic salmon (Salmo salar) died on fish farms in Scottish waters in the final months of 2024.
- Poisonous jellyfish, disease and parasites were behind the mass mortality events, despite major investments by the salmon industry to combat these threats.
- In January, a parliamentary committee concluded an inquiry into the industry, saying it was “disappointed” by the lack of progress on environmental pollution and animal welfare issues.

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

The world’s kelp needs help — less than 2% is highly protected
- Kelp forests support a kaleidoscope of biodiversity and perform crucial ecosystem functions, yet they are in trouble globally.
- A recent journal commentary shows that just 15.9% of kelp forests are in protected areas, and only 1.6% of them are in areas with the highest levels of protection.
- The authors said they hope their findings will motivate policymakers to include kelp forests in international conservation targets, such as the “30×30” mandate to protect 30% of Earth’s land and sea by 2030.

Tourists are back at this Instaworthy Philippine town, but can its sewage system keep up?
- The town of El Nido on the Philippine island of Palawan, known for its stunning limestone cliffs and azure waters, has become a popular tourist destination due to heavy social media promotion.
- But tourism has caused severe coastal contamination, with consistently high fecal coliform levels in the sea off El Nido, despite efforts like a new sewage treatment plant.
- Policies like tourist caps and subsidies for sewage connections have been introduced, but the system’s pipeline network remains insufficient, with only 3.3% of households in the town center connected to the system.
- Experts blame poor planning, overpromotion on social media, and prioritization of economic gains over environmental health, and urge stronger waste management, regulatory enforcement, and social media campaigns promoting responsible tourism.

Study suggests algal blooms disorient whales, putting them in danger
- Harmful algal blooms (HABs) in the ocean produce toxins that can sicken humans and marine animals.
- A new study has found an increase in large-whale deaths and injuries near HABs on the U.S. East and West Coasts, mainly due to ship strikes and entanglement in fishing gear.
- The authors propose the reason may be that HAB toxins disorient whales, decreasing their ability to avoid ships and fishing gear. However, they say more research is needed to confirm the link.
- They recommend using advanced HAB prediction models to reduce whale deaths by limiting activities like fishing when HABs and whales overlap.

Underwater citizen science reveals the specter of ghost fishing in Thailand
- Teams of scientists and hobbyist scuba divers have assessed the extent of discarded fishing gear on Thailand’s marine wildlife, finding it poses a pervasive threat to a huge range of species.
- Discarded or “ghost” fishing gear comprises 10% of all marine plastic debris in the ocean, persisting for decades and passively catching and killing species from sea snails to whale sharks.
- Thailand is famed for its recreational diving, and efforts are underway to retrieve ghost gear from the ocean and rescue animals found entangled, as well as to work with fishers to help them recycle their old equipment.
- Experts say preventing gear from entering the ocean in the first place is paramount; solutions must extend beyond cleanup and recycling efforts to encompass policy reform, economic incentives, and improved infrastructure.

Marshall Islands protects ‘pristine’ Pacific corals with first marine sanctuary
The Marshall Islands government has announced it will protect an area of the Pacific Ocean described as one of the most “remote, pristine” marine ecosystems on Earth.

Salmon farms under fire on U.S. East Coast after being shuttered on West Coast
- An advocacy group has sued the last company in the U.S. still farming salmon in sea cages, citing alleged violations of the Clean Water Act.
- Cooke Aquaculture runs more than a dozen sites in the northeastern state of Maine. The lawsuit accuses the company of illegally discharging pollutants, exceeding limits on effluents and nutrient buildup, and reporting violations.
- The legal action comes the same month that the state of Washington banned industrial salmon aquaculture over environmental concerns, making Maine the only U.S. state where the practice continues.
- Critics argue that netpen salmon farming not only pollutes the marine environment but also threatens wild salmon populations, while requiring the harvest of too much wild fish and krill for feed.

In Panama, major port construction begins at key mangrove site
- The Puerto Barú project, located outside the town of David in the Pacific province of Chiriquí, will be a new industrial port on Panama’s west coast, where channels and lagoons support mangroves, breeding grounds and nurseries for a variety of marine species.
- The project requires dredging a riverbed and increasing maritime traffic of cargo ships, cruise ships and yachts.
- More than 50 conservation groups have organized a “No to Puerto Barú” campaign, but an initial injunction to stop construction was shot down in court.

As Gálapagos ecotourism booms, top naturalist guide urges sustainability
- Galápagos National Park and the marine reserve protecting the islands’ surrounding waters welcome 300,000 visitors a year and support sustainable fisheries and tourism jobs for about 30,000 residents.
- The Ecuadorian government restricts the number of visitors accessing each island or dive site daily, and requires each tourist or group to hire a guide to accompany them, ensuring that maximum ecological information is shared and that park rules aimed at protecting the unique flora and fauna are followed.
- Many hundreds of Galápagos residents work year-round in this capacity, like veteran guide Marco Andres Vizcaino Garcia, who Mongabay interviewed about the challenges and opportunities he sees for ecotourism, conservation and research across these iconic islands he calls home.

Global ocean temperatures set new record in 2024
- Average temperatures across the world’s oceans reached an all-time high in 2024, according to a multi-team study published Jan. 10.
- The temperatures surpassed even those of 2023, which themselves represented a marked uptick over any previous years on record.
- Each of the two main metrics for ocean temperature hit a record high in 2024, while a commonly cited overall metric that accounts for both land and sea temperatures also reached a new high.
- The findings fit with a decades-long trend of ocean heating. The long-term rise is both a result of climate change and a cause of climate change effects like sea-level rise and increased likelihood of extreme weather.

Atlantic puffins are perilously attracted to artificial light, new study shows
- When they make their first journey into the ocean, fledgling Atlantic puffins are prone to being stranded on land, imperiling them. For years, scientists have wondered what leads to these strandings.
- A new study provides experimental evidence to show that artificial light lures young puffins toward land, contributing to strandings.
- The study found pufflings don’t have a strong preference for any particular light source or color. However, once stranded, they move more under darkness and high-pressure sodium lights than under LED lights.
- Reducing artificial lights along the coast and offshore could save puffin lives, say conservationists, as Atlantic puffin populations are decreasing in parts of Europe. It can also save other threatened seabirds, such as Leach’s storm petrel found off Canada’s coast.

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

New evidence spells massive trouble for world’s sharks, rays and chimaeras
- A third of the world’s sharks, rays and chimaeras are threatened with extinction, and their numbers have dwindled since 1970, finds a new IUCN report and a study.
- Overfishing is the biggest threat to these marine fish, halving their populations in five decades, followed by the international trade in shark parts, habitat degradation and pollution.
- Scientists call for immediate actions to prevent extinction, regulate trade and manage shark fisheries to promote sustainability.

Sunken ships in Sri Lanka’s Colombo attract more fish than coral reefs
- Shipwrecks host more diverse fish assemblages compared with natural coral reefs off the coast of Colombo, Sri Lanka’s commercial capital.
- Research shows that shipwrecks provide more complex structures with various microhabitats, attracting fish and offering both food and safety, making them more appealing than coral reefs.
- Scientists used the diver operated video recording method, in which a diver carries a video camera along a predefined transect, for allowing species identification and quantification later in the laboratory.
- Sri Lankan waters contain 115 known shipwrecks, with the oldest being the Godawaya wreck, dating back to the second century BCE, and they play a significant role in dive tourism.

Marine protection efforts in 2024 were still a drop in the ocean
Banner image: A sea turtle swims over a coral reef off the coast of Australia. Image by Jordan Robins via Ocean Image Bank.In 2022, the world agreed at a U.N. biodiversity summit to protect 30% of Earth’s land and water by 2030. While protected areas already account for almost 15% of the planet’s land, protection for the world’s oceans is lagging far behind, at just over 8%. In 2024, several new marine protected areas (MPAs) helped nudge […]
Photos: Top new species from 2024
- Scientists described numerous new species this past year, from the world’s smallest otter in India to a fanged hedgehog from Southeast Asia, tree-dwelling frogs in Madagascar, and a new family of African plants.
- Experts estimate that fewer than 20% of Earth’s species have been documented by Western science, with potentially millions more awaiting discovery.
- Although such species may be new to science, many are already known to — and used by — local and Indigenous peoples, who often have given them traditional names.
- Upon discovery, many new species are assessed as threatened with extinction, highlighting the urgent need for conservation efforts.

Pacific’s ‘Blob’ heat wave killed millions more seabirds than thought: Study
In 2016, scientists became aware of a die-off of common murres, seabirds resembling flying penguins, that were found washed ashore from Alaska to California. A 2020 study estimated, based on an extrapolation from carcasses found on beaches, that roughly 1 million murres may have died, calling it “unprecedented and astonishing,” even “biblical.” However, a new […]
‘These stories deserve to be told’: Shining a light on secretive fisheries managers
In 2024, the U.N.’s climate and biodiversity conferences, COP29 and COP16, drew the attention of more than 3,500 media delegates and 1,000 journalists, respectively. Though these massive global negotiations are consequential for international policy on the environment and have human rights implications, there were also international negotiations this year on managing the majority of the […]
Electrochemical removal of ocean CO2 offers potential — and concerns
- Stripping seawater of carbon dioxide via electrochemical processes — thereby prompting oceans to draw down more greenhouse gas from the atmosphere — is a geoengineering approach under consideration for largescale CO2 removal. Several startups and existing companies are planning projects at various scales.
- Once removed from seawater, captured carbon dioxide can be stored geologically or used commercially by industry. Another electrochemical method returns alkaline seawater to the oceans, causing increased carbon dioxide absorption over time.
- In theory, these techniques could aid in carbon emission storage. But experts warn that as some companies rush to commercialize the tech and sell carbon credits, significant knowledge gaps remain, with potential ecological harm needing to be determined.
- Achieving the scale required to make a dent in climate change would require deploying huge numbers of electrochemical plants globally — a costly and environmentally risky scenario deemed unfeasible by some. One problem: the harm posed by scale-up isn’t easy to assess with modeling and small-scale projects.

Coral destruction for toilet construction: Interview with a Malagasy fisher
- Toamasina, a coastal city in eastern Madagascar, is surrounded by an extensive network of coral reefs that are home to near-threatened species.
- For decades, these reefs have been under threat from an unusual activity: The use of coral in the construction of septic tanks.
- Mongabay spoke with Abraham Botovao, a boat skipper and the president of a local fishers’ association, who has been closely monitoring this trade and its impact on the local marine environment.
- “It frustrates me every time I see them when I’m out fishing, but unfortunately all I can do is watch without being able to do anything,” Botovao said.

A port is destroying corals to expand. Can an NGO rescue enough to matter?
- The ongoing expansion of the port of Toamasina in eastern Madagascar is set to destroy 25 hectares (62 acres) of coral reefs.
- Tany Ifandovana, a Malagasy NGO, removed a small portion of these corals before construction began, and transplanted them to a coral island several kilometers away, as a way to ecologically compensate for the losses, at least in part.
- The NGO faces major challenges, including a lack of resources, little support from the port, and locals destroying corals around the island transplant site.
- “As an environmentalist, it hurt my heart to know that these corals were just going to be filled in,” Tany Ifandovana’s vice president told Mongabay. “Something had to be done.”

European Commission to review Greek oil activity permits in whale habitat
The European Commission will reportedly “seek clarification” from Greece about its recent approvals for offshore oil and gas activities in areas critical for threatened whales and sea turtles. That’s according to the NGO ClientEarth, which, alongside WWF Greece and Greenpeace Greece, filed a formal complaint with the European executive body in 2023 alleging that the […]
Hundreds of whales to be harpooned as Iceland issues new hunting licenses
- On Dec. 6, Iceland’s interim government announced it had issued five-year commercial whaling permits to hunt fin and minke whales.
- The permits, issued to domestic whaling companies Hvalur hf and Tjaldtangi, allow the hunting of 209 fin whales and 217 minke whales each year in Icelandic waters.
- The move follows recent government decisions to briefly pause whaling based on welfare concerns about using grenade-tipped harpoons for hunting, and then resume it again.
- Conservationists say the new whaling decision is a blow to marine conservation and question its timing by an interim government that’s soon due to hand over power to a coalition that isn’t pro-whaling.

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

Time for a ‘moral reckoning’ of aquaculture’s environmental impacts
Aquaculture is often promoted as a solution to declines in wild fish populations, and has outpaced the amount of wild-caught fish by tens of millions of metric tons each year. But it carries its own myriad environmental impacts, to the detriment of both humans and the ocean, says Carl Safina, an ecologist and author. He […]
After historic 2024 coral bleaching, hope remains for Mesoamerican Reef
- The Mesoamerican Reef, the longest barrier reef in the Western Hemisphere, stretches 1,000 kilometers (620 miles) along the Caribbean coasts of Mexico, Belize, Guatemala and Honduras.
- The latest instalment of the Mesoamerican Reef Report Card, a periodic health assessment, finds that in 2024, the worst coral bleaching event on record reduced the reef’s coral cover.
- Although the overall health of the Mesoamerican Reef remains “poor,” according to the report, its health actually improved for the first time in five years.
- The report attributes this positive development to an increase in fish populations due to effective enforcement of fisheries rules by regional authorities.

As Thailand’s blue swimming crabs decline, crab banks offer a sustainable solution
- Fishing of blue swimming crabs in Thailand has historically exceeded sustainable levels, leading to a decline in both the number and size of crabs that fishers were catching.
- Understanding the urgency of recovering the crab population, fishers, government agencies, NGOs and the private sector have rolled out a series of initiatives to make the fishery more sustainable.
- These include seasonal bans on harvesting egg-carrying crabs, restrictions on trawling and certain kinds of fishing gear, and the establishment of crab banks, where egg-bearing females are nurtured, with their hatchlings later released into a secure marine site.
- Fishers and experts welcome the crab banks, but emphasize the need for a “sustainable holistic scheme,” given that a reliance on crab banks alone won’t rebuild blue swimming crab populations.

In Chile, discovery of shallowest red hydrocoral forest yet surprises scientists
- Scientists have discovered massive marine forests in southern Chile’s Kawésqar National Reserve, formed by the red hydrocoral species Errina antarctica.
- These colonies, found at depths ranging from 1.23 to 33 meters (4 to 108 feet), are the world’s southernmost and shallowest known to date.
- Experts emphasize the importance of protecting these fragile ecosystems and hope the newly discovered forests will be considered in the reserve’s management plan.

Traditional fishers in Peru guard the coast from illegal fishing
- In Chimbote, north of Lima in Peru, fishers have been working for years to protect the Peruvian grunt (Anisotremus scapularis), a fish species in high demand for its meat, along a 1.5-kilometer (almost 1-mile) stretch of coast.
- Illegal fishing methods such as explosives have become common in this area, and the authorities have failed to deter them.
- The fishers, who use traditional methods to catch the grunt from shore, keep watch for illegal activities in the area in hopes that the species will not disappear.

Norway kills first round of Arctic deep-sea mining permits amid opposition
Norway has cancelled the first licensing round for deep-sea mining in the Arctic after pressure from activists and a small environmentalist political party. Plans to mine Norway’s seabed minerals were largely expected to sail through with little opposition, as the government eyed the start of commercial mining in 2030.

On the night of Nov. 12, fishers from the riverine community of Igarapé do Costa, near the city of Santarém in northern Brazil, began […]
Desalination plants proposed for Texas Gulf Coast spur broad opposition
- Corpus Christi is a city on the Texas Gulf Coast located close to water hungry industries in the drought plagued state, attracting multiple proposals to build desalination plants that would turn saltwater into freshwater for plastic manufacturers and other industrial end users.
- Desalination uses a lot of energy but also produces brine, which can be twice as salty as seawater and can contain elevated levels of heavy metals.
- This brine is set to be pumped back into Corpus Christi Bay or further out into the Gulf of Mexico, causing an array of stakeholders from the fishing community to birdwatchers to oppose the ‘desal’ plants.
- The director of one of the grassroots action groups discusses the situation in an interview with Mongabay.

Elephant seal colonies in Argentina face long recovery after ‘catastrophic’ avian flu
- Avian flu, also known as H5N1, spread through marine mammal colonies in Argentinian Patagonia in August 2023, nearly doubling the death rate among southern elephant seals in some areas.
- In a recent land survey, researchers found no new cases of the disease among the seals, signaling an end to the outbreak, at least for now.
- But they also found that the total number of elephant seals had decreased by as much as 66% in some areas, the direct result of the high mortality rates during last year’s outbreak.
- Colonies will only recover with undisturbed seasons of breeding and molting, as well as access to abundant food, experts said.

Leaders fail to address overfishing near Europe at ‘fraught’ international meeting
- The North-East Atlantic Fisheries Commission (NEAFC) held its annual meeting in London Nov. 12-15.
- NEAFC is a regional fisheries management organization, a multilateral body that controls fishing in international waters; its remit includes certain fish stocks in the Northeast Atlantic, near Europe.
- Among these, mackerel and herring have been overfished for years, yet NEAFC member countries did nothing to address the issue at the meeting.
- NGO observers have criticized NEAFC and its members for failing to address governance issues they say led to the overexploitation.

Let’s rethink debt-for-nature swaps toward greater sustainability & integrity (commentary)
- Debt-for-nature swaps are financial mechanisms that allow countries to reduce their debt burdens in exchange for committing to environmental conservation: Ecuador’s marine conservation program benefited greatly from this kind of agreement recently.
- These are powerful tools, but to fully unlock their potential, we must rethink their structure and governance, a new op-ed argues. A more inclusive, transparent, and robust framework is needed—one built on the principles of Global Public Investment, which places equity and shared responsibility at the heart of climate and biodiversity finance.
- “Let’s turn the potential of debt-for-nature swaps into a powerful force for change, unleashing the transformative power of finance to build a sustainable and just future for all,” the authors write.
- This article is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

Protecting 2.6% of oceans could prevent deadly whale-ship collisions: Study
Ship strikes are a leading threat to large whales, with global shipping routes overlapping 92% of their habitats, a new study finds. But protecting whales in the most dangerous collision hotspots would require action over just 2.6% of the ocean’s surface, researchers conclude, potentially saving thousands of whales with minimal disruption to global trade. The […]
India advances deep-sea mining technology in the Andaman Sea
- The National Institute of Ocean Technology recently conducted an exploratory deep-sea mining trial in the Andaman Sea.
- Even as the International Seabed Authority (ISA), is yet to finalize the mining code for commercial purposes, those with exploratory licenses have been conducting mining trials in international waters.
- The opposition to deep-sea mining, citing environmental impact, is also at an all-time high.

Scottish salmon farms seek growth despite mounting fish deaths and environmental concerns
- Scotland is the world’s third-largest producer of farmed Atlantic salmon (Salmo salar), after Norway and Chile.
- The industry is seeking to significantly increase production in Scotland, driven by growing export demand.
- However, it faces ethical concerns over mounting fish mortality, as well as environmental concerns about pollution, the proliferation of sea lice affecting wild salmon, and opposition from several local communities.
- Industry members acknowledge the challenge of growing salmon amid rising sea temperatures, but say Scottish salmon farms have made progress in managing sea lice and other health challenges.

A father and son duo fight invasive lionfish on a Honduran reef
- Live coral covers 68% of Tela Bay, on the northern coast of Honduras, creating a complex ecosystem that’s part of the wider Mesoamerican Reef system.
- Among stressors including overfishing and coral bleaching due to climate change, is the invasive lionfish — a spectacular-looking, venomous, striped fish native to the Indo-Pacific that, with no natural predators here, is wreaking havoc on marine ecosystems throughout the Caribbean.
- To protect Tela Bay’s embattled coral reef, a local father and son are mounting a single-minded lionfish hunting effort to limit the fishes’ spread, hunting the fish themselves and organizing hunting competitions.

Mapping ‘gloop and mud’ sheds light on seabed carbon storage
- Two new reports showing the extent of carbon storage in the marine sediments around the coasts of Canada and the U.K. are helping to build the case for greater protection of the seabed, as part of efforts to mitigate climate change.
- They also highlight some of the threats to this underwater carbon sink, particularly sediment disturbance caused by bottom trawling, a fishing method.
- A new project funded by the U.K.’s Natural Environment Research Council is set to investigate whether or not continued disturbance poses the risk of turning the seabed into a source of CO₂.

Coral biodiversity hotspot at risk from fossil fuel expansion, report warns
- A new report warns that the expansion of oil, gas and liquefied natural gas projects in the Coral Triangle region in the Western Pacific risks unleashing more oil spills, direct damage to coral reefs, noise pollution and ship traffic, not to mention greenhouse gas emissions.
- More than 100 offshore oil and gas blocks are currently in production, and more than 450 additional blocks are earmarked for future exploration, according to the report. If these projects are approved, the production and exploration blocks would cover 16% of the Coral Triangle, an area the size of Indonesia, the report states.
- The report notes there is already overlap between oil and gas operations and critical conservation zones, including 16% of the Coral Triangle’s marine protected areas.
- The Coral Triangle is one of Earth’s most biodiverse regions, stretching across the waters of the Philippines, Indonesia, Malaysia, Papua New Guinea, Timor-Leste and the Solomon Islands. It’s home to 76% of all known coral species, as well as numerous endangered marine species.

Peruvian fishers help red sea urchins recover from overfishing
- For 20 years, fishers from the district of Marcona, on Peru’s southern coast, have been recovering populations of red sea urchin, thanks to an alliance with the government.
- According to a monitoring study by the Peruvian Institute of the Sea, there are more urchins in the area where Marcona fishers work than in other areas.
- Part of the success is rooted in the spatial management of coastal areas that the artisanal fishers’ associations are applying; they are pioneers of this practice in the country.

Court throws out permits for controversial Baja California hotel project
- The Tres Santos hotel project in Baja California Sur will have to conduct new environmental impact studies in order to obtain permits that it failed to comply with when breaking ground nearly a decade ago.
- Over the last decade, residents said the environmental impact became worse than what had originally been described to them. Some wetlands were filled in and rivers and streams were being diverted.
- Earlier this year, a court found that the original environmental impact study didn’t justify the development that was carried out. It should have been rejected and done again before construction even started.

How the oceans fared at the COP16 biodiversity conference in Colombia
- The United Nations Convention on Biological Diversity summit (COP16) took place in Cali, Colombia, from Oct. 21 to Nov. 2.
- Several oceans-related decisions, as well as the formal inclusion of Indigenous peoples and local communities in negotiations going forward, were bright spots at the summit, observers said.
- A key development for the ocean was the agreement, culminating eight years of negotiations, on a protocol for identifying unique areas of the high seas, the two-thirds of the world’s oceans that are international waters, for protection.
- Other important developments included the announcement of new marine protected areas and new funding for ocean conservation.

Indonesia fisheries minister eyes aquaculture expansion under Prabowo
- Indonesia’s new president, Prabowo Subianto, has retained incumbent fisheries minister Sakti Wahyu Trenggono to oversee expansion in productivity in captive fisheries over the next five years.
- Sakti has pledged to revive ailing aquaculture ponds, most of which are located on the northern coast of Java, where numerous village fishing economies are struggling amid depleted near-shore fish stocks and coastal development.
- In July, Indonesia’s then-vice president, Ma’ruf Amin, told a fisheries summit that climate change, biodiversity loss and environmental damage had hindered the output of near-shore fisheries in the world’s largest archipelagic country.

Population crash means African penguins are now critically endangered
The endangered African penguins (Spheniscus demersus)Africa’s only resident penguin species is now officially critically endangered, according to a recent assessment by the International Union for Conservation of Nature (IUCN). Over the past century, the African penguin (Spheniscus demersus) has suffered precipitous declines in its population. In the mid-1950s, there were an estimated 141,000 breeding pairs of African penguins, or 282,000 […]
‘Don’t call it the high seas treaty’: Ocean biodiversity risks being sidelined in new deal
Hammerhead sharks.The global treaty designed for the “objective of the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction,” adopted last year, has more recently gained an inaccurate, but popular, nickname, and lacks independent enforcement, according to some observers.

Half of the MPA network is “fully protected,” while the […]
At COP16, the ocean needs action, not more promises (commentary)
- As delegates to COP16 debate conservation measures like 30×30 initiatives, a new op-ed by the environment director of Bloomberg Philanthropies, Antha Williams, and the founder of Pristine Seas, Dr. Enric Sala, says that protecting our ocean is more than a conservation measure — it’s a lifeline.
- Well-managed and highly protected marine areas (MPAs) help restore ecosystems, ensuring food security and livelihoods for the billions who depend on them, but a new analysis shows that only 8.3% of the world’s ocean is protected in this way, and that most MPAs are either protected weakly or in name only.
- “Ocean protection has never been more urgent. As leaders gather in Cali, they must ensure that ‘protecting our ocean’ means truly protecting it. The 30×30 target will only be meaningful if we protect areas effectively — not just on paper,” they argue.
- This article is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

More krill fishing and no new protected areas for Antarctic seas after latest talks
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) held its annual meeting Oct. 14-25 in Hobart, Australia.
- The international body comprised of 27 members is charged with conserving marine life in Antarctic waters, an area that is changing rapidly due to human-caused climate change.
- In 2009, the CCAMLR pledged to create “a representative network” of marine protected areas in the Southern Ocean, yet negotiations over four proposed MPAs have been at a standstill for years, due to repeated vetoes by the Chinese and Russian delegations.
- Despite a year of interim negotiations, CCAMLR members failed again at the latest meeting to reach agreement on creating any new marine protected areas and rolled back regulation of the burgeoning Antarctic krill fishery.

Protecting coral reefs boosts fish numbers by 10%: Study
- New research has found that the protection of coral reefs has boosted the amount of fish they harbor by around 10%.
- The study used survey data from about 2,600 reefs with varying levels of protection from overfishing.
- The team then built a statistical model to predict what would have happened if all reefs had not been protected, and the biomass, or collective weight of the resident fish, dropped by more than 10%.
- The scientists note their findings demonstrate that protections like marine protected areas are working and that greater coverage could lead to even more gains in fish biomass.

New abuse allegations hit China ghost ships in Indonesia waters
- In mid-April this year, several Indonesian crew members aboard the China-based Run Zeng 03 fishing vessel jumped into the Arafura Sea following a pattern of alleged mistreatment on board.
- One of those who jumped didn’t survive, while the others were rescued by a fishing boat that happened on the crew members fighting for life in the water.
- Authorities in Indonesia may have missed opportunities to confine boats operated by Donggang Runzeng Ocean Fishing Co Ltd, a Chinese company based in a port on the country’s border with North Korea.
- The Indonesian fisheries ministry’s head of supervision explained in an interview that his history of contact with the manager of the boats’ operator was part of a law enforcement operation.

Debate over Chile’s fisheries law exposes industry influence on fish management
- A new fisheries law is being debated in Chile’s Chamber of Deputies.
- Three members of Congress have recommended more than 200 changes to the proposed law that align with the main arguments put forward by large fishing conglomerates belonging to the country’s main industry group.
- One of these recommendations seeks to remove an article that would limit bottom trawling, a fishing method many scientists criticize due to its impact on marine ecosystems.
- The debate is exposing the industry’s influence on fisheries management in Chile, some experts say.

Near-extinct North Atlantic right whales get a small population boost
The population of the critically endangered North Atlantic right whale increased by five individuals, bringing the estimated total to 372 in 2023, according to an Oct. 22 report. The North Atlantic right whale (Eubalaena glacialis) population has declined since 2011. However, the slight rise in recent years may signal some stability for these ocean giants, […]
Studies identify microplastics contamination along entire Brazilian coastline
- Numerous projects are measuring the impacts of plastics in Brazilian seas; methods range from beach sampling to analysis of mollusk digestive tracts.
- Brazil discards 3.4 million tons of plastic every year, a third of which reaches the coast; it is estimated that between 86 million and 150 million tons of plastic residue have accumulated in the ocean here.
- A bill has been introduced in Brazil to promote plastic recycling. On the global level, the Global Plastics Treaty is being negotiated by 175 nations to diminish single-use plastic pollution.

Fishers & scientists unite to restore seaweed populations on Chilean coast
- Scientists and fishers in Chile are repopulating a coastal area exposed to high levels of pollution with two species of seaweed that were once abundant in the area.
- The disappearance of the seaweed has formed ocean deserts. Its absence has not only reduced biodiversity but also deprived the area of the ecosystem services that these plants provide.
- Despite considerable challenges, the project already shows signs of hope.

Scientists discover new hammerhead shark species — and it’s already at risk
A new-to-science hammerhead species, the shovelhead shark, has been hiding in plain sight for three centuries due to its close resemblance to a long-lost relative, the bonnethead shark. After a decade of research, a breakthrough study published Sept. 24 found that these are two distinct species, challenging the widely accepted 1758 description by biologist Carl […]
Research proving impact of ocean acidification on marine life urgently needed: Report
Coral reef.A group of marine scientists is calling for focused research that provides “incontrovertible evidence” of how ocean acidification impacts marine life. In a report published Oct. 16., the scientists say that studies establishing a direct causal link between acidification and marine life are currently lacking, but are needed so policymakers can make informed decisions. Ocean […]
The disappearing red ghost crabs of Cox’s Bazar, a conservation crisis in Bangladesh
- Cox’s Bazar Beach in southeast Bangladesh is known for its vibrant red crab population, which creates a stunning spectacle in the early mornings and late afternoons. However, this natural wonder is now threatened by human activities and environmental degradation.
- Red ghost crabs benefit coastal ecosystems by aerating sand and improving water infiltration, and also as prey species. Their decline threatens the ecosystem health.
- Researchers say a beach management plan is crucial for their protection and restoration. Protected areas like in Kuakata have shown effectiveness in conserving ghost crabs. Raising awareness among local communities is also crucial for successful conservation efforts in Bangladesh.

Hotel built without permits on disputed land riles neighboring Paracas reserve in Peru
- A controversial hotel opened its doors to the public in 2023 in the Paracas National Reserve’s buffer zone, which acts as a protective strip around the reserve to minimize any impact on the protected area.
- The Hotel Boutique Atenas is owned by a former police officer with a history of land ownership conflicts. The hotel does not appear to have the required permits from Peru’s National Service of Natural Protected Areas, Mongabay Latam found.
- It was also built on a property currently subject to a land dispute. Marine farmers who work there claim to have been forcefully displaced from this area.

Norway poised to sail past opposition with deep-sea mining licensing plans
- In June, Norway proposed 386 license areas in the Norwegian Sea for future deep-sea mining activities.
- During the ensuing three-month public consultation period, the government received more than 70 responses from various organizations and members of the public. The responses offered a mix of views: the majority opposed Norway’s deep-sea mining plans, a minority expressed support, and many across the board called for more research.
- One entity criticizing Norway’s plans is the country’s own environment agency, which argued that there’s a lack of knowledge to safely pursue deep-sea mining while protecting the marine environment.
- Norway’s government has stated that it intends to begin issuing licenses in 2025 with a view to starting seabed mineral exploitation in 2030.

Rate of ocean warming has nearly doubled in the last two decades: Report
The world’s oceans are warming at an unprecedented rate. According to the EU Copernicus’ 8th Ocean State Report released this week, the rate of ocean warming has nearly doubled in the last 20 years. Roughly 22% of the global ocean surface experienced at least one severe to extreme marine heat wave event in 2023, according […]
Cambodian fishers-turned-citizen scientists monitor marine mammal deaths
- In Cambodia, the NGO Khmer Ocean Life has trained residents of coastal fishing communities about threats to marine mammals so they can participate in a citizen scientist network aimed at tracking bycatch and strandings.
- At least 10 species of marine mammals are commonly found in Cambodia, including dugongs (Dugong dugon), Indo-Pacific finless porpoises (Neophocaena phocaenoides), Indo-Pacific humpback dolphins (Sousa chinensis) and endangered Irrawaddy dolphins (Orcaella brevirostris); all of these species face an array of threats, including coastal development and unsustainable fishing practices.
- Bycatch is the biggest threat facing marine mammals globally, according Sarah Tubbs, Khmer Ocean Life’s co-founder and co-director, and coastal marine mammals face greater threats due to their proximity to fishing activities.
- Currently, data on marine mammal bycatch and strandings are lacking in Cambodia; the citizen scientist network will provide real-time insights into where bycatch mitigation efforts are most needed.

‘Mermaids’ dive to study and protect Mexican fishing grounds
- For more than 20 years, a fishing cooperative in the community of Isla Natividad, in Baja California Sur, Mexico, has been working to adapt and to be more resilient to climate-change impacts like tropical storms, marine heat waves, hypoxia and loss of kelp forests; these latter shelter species that help feed the community but have experienced mass mortality, such as the abalone.
- The community has invested in diversifying their economic activities and have established volunteer-run marine reserves. Their aim is to help affected fish stocks recover.
- A group of citizen scientist divers known as the Sirenas de Natividad was founded in 2019; this all-women team is made up of five homemakers, all wives and daughters of fishers, who are monitoring fishery resources and the volunteer-run marine reserves.

In the Pacific depths, an underwater mountain hosts a bonanza of new species
- Scientists discovered a new underwater mountain and more than 100 potentially new-to-science species during recent expeditions in the Southeast Pacific, including rare creatures like flying spaghetti monsters and Casper octopuses.
- The newly found seamount, located about 1,450 km (900 mi) off Chile’s coast, rises 3,100 meters (nearly 2 miles) from the seafloor and hosts thriving deep-sea ecosystems with ancient corals and glass sponges.
- These findings highlight the rich biodiversity of the high seas and come at a crucial time as the U.N. finalizes the high seas treaty to protect international waters.
- While the treaty sets rules for marine protected areas, challenges remain in its implementation, including formal adoption and ratification by at least 60 countries.

NGOs say EU Commission must act on Greece oil activity in whale habitat
Environmental NGOs are urging the European Commission to pursue their complaint about Greece’s approval of offshore oil and gas concessions in a crucial habitat for whales, after the executive body previously said the matter did not need it’s intervention. “The Greek state is persistently avoiding carrying out the required assessments on marine biodiversity and marine […]
Social media influencers’ bad behavior with marine wildlife is risky for animals, too (commentary)
- Social media accounts which showcase close encounters with marine wildlife — from whales to white sharks and manta rays — have become common and popular.
- A distinctive feature of these is the presence of people in the images, where the focus is frequently on the individual near – or sometimes in direct contact with – the species: the main subject is not the animal itself but the human interacting with it, which puts both people and wildlife at risk.
- “In these experiences, what many of us often seek – a unique connection with a species different from our own – overlooks a fundamental principle: marine wildlife does not need our friendship, but rather our protection,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Celestún refuge fights illegal fishing & helps revive species in Mexico’s Yucatán
- In 2019, the Celestún fishing community in Yucatán, Mexico, established a 324-square-kilometer (125-square-mile) Fishing Refuge Zone (FRZ), the largest in the Gulf of Mexico.
- The area was created in response to the overfishing of sea cucumbers, a species that had been in rapid decline, which caused social strife in the community.
- Local fishers have been trained to monitor the refuge to help the species recover and protect other species of commercial interest, like octopus and lobster. The participation of women has been an important part of the process, as they help lead community monitoring efforts.

In Mexico, scientists race to save Marietas Islands’ corals from ocean warming
- Temperatures in the Pacific Ocean broke records in 2023 as climate change and El Niño destroyed a large part of Mexico’s Islas Marietas National Park.
- Only a fifth of the coral coverage registered in 1995 still survives, experts say.
- But scientists working on the islands have discovered individual corals that can resist higher temperatures, creating hope that the corals can recover.

Plan for close season rings alarm bells for Liberia’s artisanal fishers
- Liberia revealed plans in May for a close season for fishing, but still hasn’t given any details of what it covers, whom it will apply to, or even when it will come into force.
- Policymakers say a pause in fishing activity is necessary to allow stocks to replenish, and is also an obligation for Liberia under a regional fisheries bloc whose other members have also planned or even implemented close seasons.
- Liberia’s small-scale fishers say the plan could be a solution to dwindling catches, but say there must be some form of livelihood support for them during the period when they can’t fish.
- They also say a close season must apply first and foremost to the industrial vessels that harvest a large amount of the country’s fish, including from nearshore waters that are supposed to be the exclusive domain of small-scale fishers.

Clock ticks on Indonesia shark skinners as predator population plunges
- Indonesia accounts for more sharks caught in open water than any other country, but fish stocks around the main island of Java are in crisis due to years of overfishing by large vessels using purse seine nets.
- In the fishing port of Brondong, a major landing site in East Java province, fishers continue to process dozens of species of sharks caught increasingly far from the world’s most populous island.
- Shark conservation is attracting increasing international attention because of the relative lack of protection and awareness of the predators’ roles in ocean ecosystems.

Amid haze of war, Lebanese activists helped turtle hatchlings journey to sea
- The sandy beaches of South Lebanon are a crucial nesting ground for sea turtles.
- This year, 2,500 sea turtle hatchlings safely reached the Mediterranean from Al-Mansouri Beach, a key nesting site near the city of Tyre, according to a volunteer group that has been tending the beach and its turtles for two decades.
- Despite the escalating conflict with Israel and the prevailing climate of fear, the volunteers continued their efforts to protect both the animals and the beach.
- On Sept. 23, the leader of the volunteer group told Mongabay she had to flee her home in Tyre after surviving several Israeli air strikes.

Global fisheries must change to avoid ocean collapse, study says
A new study by an international team of scientists finds that industrial fishing is driving the world’s oceans toward collapse. The report outlines 11 key actions needed to maintain healthy oceans, including the reduction of harmful fishing methods and keeping fish populations at 60% of their natural levels. One recommendation offered in the report is […]
NGOs raise concerns over oil exploration in Republic of Congo national park
- NGOs are calling on the government of the Republic of Congo to revoke a permit allowing oil exploration in Conkouati-Douli National Park, the country’s most biodiverse area.
- They argue that oil exploration and exploitation will have a catastrophic impact on the park and local communities living in and around it.
- They also argue that the project runs counter to agreements reached with international donors to fund forest protection and breaks the Republic of Congo’s own environmental law.

Five times more marine fish may be at risk of extinction: study
What’s new: The number of bony marine fish species at risk of extinction could be five times higher than previously estimated by conservation scientists, a recent study suggests. What the study says: Bony fish, or teleosts, represent some 96% of the world’s marine fish species. The IUCN Red List of Threatened Species, the global reference […]
Mexico loses phosphate mining lawsuit in controversial arbitration process
- Odyssey Marine Exploration, a deep-sea mining company based in Florida, sued Mexico after rejecting environmental permits for a phosphate mining project off the coast of the state of Baja California Sur.
- The company brought Mexico to arbitration through an obscure legal process known as an investor-state dispute settlement, which allows foreign companies to directly sue countries they’ve invested in.
- Investor-state dispute settlements have been criticized for their lack of transparency and public participation, offering few guaranteed rights to affected communities.

Inaugural Planetary Health Check finds ocean acidification on the brink
- A first of its kind Planetary Health Check by an international team of scientists indicates that six of nine planetary boundaries are not only transgressed, but are moving further into zones of risk. In addition, recent research shows that a seventh boundary, ocean acidification, is on the verge of transgression.
- Intensifying ocean acidification spells problems for marine life, fisheries and economies. Based on current human CO₂ emission trajectories, this boundary may be breached in a few years, say experts. Others argue this threshold may already have been crossed, with regional acidification above safe limits.
- Together, the nine planetary boundaries identify limits within which Earth systems can operate safely to maintain the planet’s habitability. Transgressing boundaries heightens risks of breaching tipping points that would bring about irreversible shifts to the planet, threatening humanity and life as we know it.
- This inaugural Planetary Health Check is the first of yearly scheduled reports on the wellbeing of Earth systems. Annual reports are now needed due to humanity’s rapid crossing of planetary boundaries, and due to the urgency of providing up to date scientific data to policymakers.

Lab-grown corals resisted bleaching during Caribbean’s worst marine heat wave
- In 2023, the Caribbean Sea experienced unprecedented heat: Beginning in March, sea surface temperatures throughout the region ranged from 1°-3°C (1.8°-5.4°F) warmer than normal.
- This unprecedented heat brought the worst coral bleaching event in the Caribbean’s recorded history, bleaching 60-100% of some reefs, and killing many patches.
- A new study found that certain species of coral propagated in the lab and then outplanted to restore reefs in five countries showed few signs of bleaching despite the prolonged marine heat wave, faring better than wild corals or corals propagated from fragments.

Fishing in a fog: Ship noise hampers orcas’ hunting success
Underwater noise from ships is making it tough for killer whales, or orcas, to find and catch their favorite fish, a recent study has found. Orcas (Orcinus orca) rely heavily on sound to hunt. They emit ultrasonic echolocation clicks that bounce off objects. By listening for the echoes of these clicks, the orcas can identify […]
The ocean ‘belongs to all of us’: Interview with Palau President Whipps
- The President of Palau, Surangel S. Whipps Jr., has been calling for a moratorium — an official pause — on deep-sea mining in international waters for more than two years now, and he continues to reiterate his position.
- Palau has banned deep-sea mining in its national waters, but Whipps says his country is calling for a moratorium, rather than an outright ban, on seabed mining in international waters since the ocean “belongs to all of us.”
- While plans are progressing to allow deep-sea mining to start in international waters — and in some countries’ national waters — Whipps says he believes the world is starting to understand the importance of the deep sea as a growing number of nations call for a moratorium.

Maldives drops plan to reopen longline tuna fishing following protests
Longline fishing for tuna will remain closed in the Maldives, the island country’s president announced on Aug. 29. The decision came after local fishers, conservation NGOs and scientists protested against plans by the administration of President Mohamed Muizzu to reopen longline fisheries for yellowfin tuna and bigeye tuna. Longline fishing has been banned in the […]
A Mexican marine park shelters giant manta rays: Interview with Madalena Pereira Cabral
- For more than four years, marine biologist Madalena Pereira Cabral has been dedicated to investigating and understanding the movements of giant manta rays (Mobula birostris) in Revillagigedo National Park in the Mexican Pacific.
- Using satellite tags, the expert aims to describe these animals’ routes through the ocean and the reasons behind the fact that almost all the individual manta rays she has been studying end up leaving the marine protected area. Leaving this area exposes them to fishing pressure, which puts them at risk.
- One of the scientist’s most important findings is that giant manta rays’ movements and the groups they form are influenced by the El Niño phenomenon. This information is crucial for the conservation of this little-understood species.

Famous ‘spy’ beluga whale found dead in Norway
A beluga whale nicknamed Hvaldimir, who was initially suspected of being a Russian spy, was found dead on Aug. 31, according to Norwegian media. Hvaldimir’s body was first spotted by a father and son who were out fishing for mackerel near the port town of Risavika in southwestern Norway. “This morning, after receiving a sighting […]
Not merely ‘exploration’: PNG deep-sea mining riles critics & surprises officials
- Deep Sea Mining Finance (DSMF), an obscure company registered in the British Virgin Islands, recently conducted an exploratory mining operation off the coast of New Ireland province in Papua New Guinea (PNG), according to civil society members and a government official’s statements to the media.
- Satellite-based vessel-tracking data show that much of this mining activity took place in and around a controversial project site known as Solwara 1, where mineral-rich hydrothermal vents are located.
- Critics say the operation was illegal and that DSMF’s activities flout two ongoing moratoria that should prevent deep-sea mining in PNG’s territorial waters. On the other hand, a national official has said the company operated within its rights to explore the deep sea for minerals.
- The operation appears to have caught many by surprise, including government authorities meant to oversee such activities.

$35m debt-for-nature deal aims to protect Indonesia’s coral reefs
- A $35 million debt-for-nature swap between Indonesia and the U.S. aims to conserve coral reefs in eastern Indonesia over the next nine years, with the funding offset by canceled sovereign debt payable to the U.S.
- Indonesian conservation groups and their international partners will implement ground programs to protect reefs in key areas, strengthen marine protected areas and support community livelihoods under the deal.
- While environmentalists welcomed the funding, some argued debt swaps were insufficient to address the larger environmental and development challenges faced by countries in the global south.

South Africa seeks to settle landmark African penguin lawsuit
South Africa’s new environment minister is calling for an out-of-court settlement with conservation groups that earlier this year filed a case against his predecessor for not doing enough to protect plummeting populations of African penguins. Dion George, who took office in July, made the announcement on Aug. 20 via his Democratic Alliance party, adding he […]
Federal court requires stronger protections for endangered Rice’s whale
A U.S. District Court in Maryland recently ruled in favor of a coalition of environmental groups, finding that a federal assessment of oil and gas activities’ impact on the critically endangered Rice’s whale was flawed. Rice’s whales (Balaenoptera ricei) were identified as a new species in 2021 after a dead whale with plastic in its […]
Argentina weighs new MPA to curb international fishing frenzy in ‘Blue Hole’
- Creation of the “Blue Hole” marine protected area in the South Atlantic Ocean would protect thousands of square kilometers of seafloor from bottom trawling and require better working conditions on vessels fishing there. But the bill that would do so has stalled in Argentina’s Congress for years and will expire in November.
- The marine protected area would cover 148,000 square kilometers (57,100 square miles) of Argentina’s continental shelf, where global fishing fleets carry out unregulated fishing, including bottom trawling.
- The Blue Hole protected area would protect the seabed from bottom trawling but continue to allow fishing in the water column above it.
- Ratification of a U.N. treaty could enable Argentina to protect the area from all forms of fishing in the future.

New species of skate is named, 35 years since its discovery off Madagascar
Toward the end of 1988, the Russian research vessel RV Vityaz visited a remote underwater seamount off the island of Madagascar. The researchers on board collected several specimens of sharks, skates and rays in a bid to understand the region’s marine life better. More than three decades later, scientists have confirmed that six of those […]
Recently hatched baby skate offers hope for endangered Tasman species
A captive-breeding program for the Maugean skate, one of the rarest marine fish in the world, has given researchers hope: a baby Maugean skate has hatched from an egg laid in captivity, for the first time ever. The Maugean skate (Dipturus maugeanus; formerly Zearaja maugeana) is today known to occur only in Macquarie Harbour, an […]
As waterbodies lose oxygen, are we breaching a potential planetary boundary?
- A new perspective piece argues that aquatic deoxygenation — the depletion of oxygen in marine and freshwater environments — should be considered its own “boundary” in the planetary boundary framework first proposed by scientists in 2009. Human-caused nitrogen pollution and climate change have greatly worsened aquatic deoxygenation worldwide.
- The planetary boundary framework defines nine natural biophysical and biochemical system processes that maintain the resilience of the Earth system, allowing life to thrive. But each boundary includes limits within which humanity needs to safely operate.
- The paper’s lead author says that increased scientific understanding of dissolved oxygen in marine and freshwater environments shows that it regulates, and is regulated by many of the other planetary processes, which in turn warrants the inclusion of aquatic deoxygenation in the planetary boundary framework.
- The framework is a rapidly evolving theory. Whether aquatic deoxygenation is already indirectly taken into account by the existing framework, as some argue, or whether it should be considered as its own planetary boundary remains to be determined.

Japanese ship hunts massive fin whale, country’s first in 50 years
Japanese commercial whalers recently killed their first fin whale in 50 years. The fin whale (Balaenoptera physalus), the world’s second-largest whale, after the blue whale (Balaenoptera musculus), can grow to up to 27 meters (88 feet) in length. Industrial whaling until the mid-1900s severely depleted their populations, and the species is classified as vulnerable to […]
On Canada’s West Coast, clam gardening builds resilience among Indigenous youth
- The Nuu-chah-nulth Youth Warrior Family, also known as the Warrior Program, fosters leadership skills in boys and young men across several Indigenous Nuu-chah-nulth nations on the west coast of Vancouver Island in British Columbia, Canada.
- This youth-led program involves taking younger community members into ancestral lands for a variety of traditional activities, among them building and reviving clam gardens, an ancient maricultural method.
- Clam gardens consist of terraced rock walls built across small coastal bays that allow tidal sediment to accumulate and transform rocky or steep shores into flat, productive areas for clams. Clam garden construction and care, along with other cultural practices, such as hunting, spearfishing and medicinal-plant foraging, serve as rites of passage, helping Warrior Program youth reconnect with their heritage.
- This report’s companion video won 2nd place for Best Coverage of Indigenous Communities as part of the 2025 Indigenous Media Awards.

Mexican fishing industry rep killed after denouncing illegal fishing
- Minerva Pérez Castro, the Baja California representative for the Mexican fishing industry’s main trade group, was killed in July after speaking out against the presence of organized crime in the fishing industry.
- Sophisticated organized crime groups have long participated in illegal fishing in northern Mexico, one of the most important producing areas for the country’s prominent fishing industry.
- The residences of several suspects have been searched, according to the Attorney General of the State of Baja California.

Brazil’s Carvalho to lead seabed-mining authority following predecessor’s controversial term
- Brazilian oceanographer Leticia Carvalho will be the next secretary-general of the International Seabed Authority (ISA), the U.N.-mandated organization that oversees deep-sea mining activities in international waters.
- She won the election with 79 votes, while her predecessor, 64-year-old Michael Lodge, who served as the ISA’s secretary-general for two terms, received only 34 votes.
- Lodge has previously been accused of siding with mining companies, which went against the duty of the ISA secretariat to remain neutral and may have influenced the direction of the prospective deep-sea mining industry.
- Carvalho previously told Mongabay that she would work to make the ISA more transparent and rebuild trust within the organization.

Shark ‘Fitbit’ captures rare footage of collision with boat
A Fitbit-like device has captured the first known footage of a boat striking a basking shark, according to a new study. The basking shark (Cetorhinus maximus), the world’s second-largest fish, is endangered due to historical overfishing and government culling programs. But sightings have increased off the coast of Ireland, where basking sharks aggregate to feed […]
WTO negotiations flounder — again — over banning unsustainable fishing subsidies
- The WTO’s General Council meeting in Geneva in July failed again to finalize a treaty to stop “harmful” fishing subsidies that enable unsustainable fishing, hindered by India’s objections.
- Only 81 out of 166 member states have formally accepted the partial “Fish One” agreement, and progress on “Fish Two” remains stalled.
- Harmful subsidies continue to deplete fish stocks, jeopardizing marine ecosystems and food security for 3 billion people.
- In light of the 25-year struggle for international consensus, some observers suggest states instead strike bi- or plurilateral agreements to eliminate harmful subsidies.

Sharks have cocaine in their bodies
Cocaine has found its way into sharks at sea, a new study has found. Researchers dissected 13 Brazilian sharpnose sharks (Rhizoprionodon lalandii) caught by artisanal fishers in the waters off Brazil between September 2021 and August 2023. All 13 sharks had trace amounts of cocaine, while 12 were positive for benzoylecgonine, one of the metabolites […]
Cambodia’s largest mangrove forest is ‘teeming with life,’ biodiversity survey finds
- A survey of biodiversity in Cambodia’s Pream Krasop Wildlife Sanctuary and Koh Kapik Ramsar site identified more than 700 unique species.
- The study also highlights how biodiversity is being lost due to threats including habitat loss and hunting; while this survey recorded rare species including otters and pangolin, a decade ago there would have been tigers and dugongs in the area.
- The researchers plan to conduct further surveys, focusing on the marine environment of the mangrove zone.

Conservationists look for new ways to fight oil pipelines in southern Mexico
- Pipelines currently under construction in southern Mexico have become controversial because of threats of chemical spills, their contribution to climate change and the alleged lack of consultation with local communities.
- The projects include the Southeast Gateway Gas pipeline and Tuxpan-Tula pipeline, both constructed by the Federal Electricity Commission and the Canadian company TC Energy.
- A 2018 injunction against the Southeast Gateway Gas Pipeline was struck down after a court ruled the project was a matter of national security. Now, local communities and conservation groups are working to develop alliances with international groups to come up with a different legal strategy.

Anti-whaling activist Paul Watson arrested in Greenland
Prominent environmental activist Paul Watson has been arrested in Greenland, reportedly for his past interventions against Japanese whalers, according to a statement from his foundation.

Shaping the next generation of Indigenous rangers: Interview with Manni Edwards
- Aboriginal elders in the far north of Australia’s Queensland state are preparing the next generation of junior rangers to conserve endangered southern cassowaries, take care of their traditional land, safeguard their culture, and hold on to millennia of acquired knowledge.
- Along with declining southern cassowary numbers, traditional knowledge and values are diminishing in youth who put more attention on Western knowledge and technology.
- The young rangers not only spend time learning in classrooms; they also go out into the traditional country with elders who help shape their character and identity as caretakers of their people, land, Mother Earth and themselves.
- Ranger Manni Edwards says the way to effective conservation in his community, and in Australia, is by bringing together scientific and traditional ecological knowledge, which includes wisdom and values that forge a connection between people and nature.

‘Trust needs to be rebuilt’: Interview with candidate to head U.N. seabed-mining authority
- Leticia Carvalho, a Brazilian oceanographer and international civil servant, is running for secretary-general of the International Seabed Authority (ISA), the regulator of deep-sea mining in international waters, at a pivotal time for the deep-sea mining sector.
- Carvalhos’s opponent is Michael Lodge, a barrister from the U.K. who has served as the ISA secretary-general for two terms and is running for a third as a candidate from Kiribati.
- The election will take place at the ISA assembly meeting in Kingston, Jamaica, between July 29 and Aug. 2, 2024.
- Carvalho told Mongabay she believes it’s time for a change in leadership due to the principles of geographic rotation and gender equality, but also because she believes the ISA needs improvement in its management and governance.

French Polynesians revive traditional rāhui to protect fish — and livelihoods
- In French Polynesia, fishing is of paramount importance. Many residents depend on fishing to feed their families and make a living.
- Confronted with a decline in fish stocks, communities across the country are reviving a traditional method of managing natural resources called rāhui.
- This bottom-up solution, managed by local communities with help from scientists and the government, although imperfect, appears to demonstrate some degree of effectiveness.
- The island of Tahiti currently counts 13 rāhuis, and more communities are establishing them as a way to fight poverty, sustain fishers’ incomes and regain their culture.

For the first time ever, we’re farming more seafood than we’re catching: FAO
- For the first time in history, we now farm more seafood than we catch from the wild.
- At the same time, overfishing of wild fish stocks continues to increase, and the number of sustainably fished stocks declines.
- Those are among the key findings of the 2024 installment of the flagship global fisheries and aquaculture report from the U.N.’s Food and Agriculture Organization (FAO). The biennial report provides data, analysis and projections that inform decision-making internationally.
- Sustainably growing aquaculture and better managing fisheries are central to the FAO’s “Blue Transformation road map,” a strategy for meeting the U.N.’s Sustainable Development Goal 14, which seeks to improve the social, economic and environmental sustainability of aquatic food to feed more people more equitably. However, progress is “either moving much too slowly or has regressed,” the report says.

‘It is indeed our problem’: Interview with Mário Soares on Brazil’s mangroves
- Mário Soares, a professor of biological oceanography at Rio de Janeiro State University who leads the Mangrove Studies Center (NEMA), has spent more than 30 years studying Brazil’s mangroves, their role in climate change, the effects of oil spills and the importance of mangrove conservation.
- While mangroves fetch a lot of attention in conversations about carbon sequestration, Soares argues that they serve numerous purposes in mitigating climate change; they are also vulnerable to the effects of climate change and must be conserved so that they, in turn, can reduce the vulnerability of the coastal zone.
- Soares also says the carbon market doesn’t solve the problem, only the symptom, because it applies “the market logic,” which created the problem in the first place; meanwhile, we’re not reducing emissions.
- Soares recently spoke to Mongabay about the history and future of Brazil’s mangroves in a video interview.

In northern Spain, climate change is killing shellfish — and women’s livelihoods
- In Galicia in northwestern Spain, shellfish harvesting is traditionally women’s work.
- But the clams and cockles the shellfish pickers’ livelihoods depend on are increasingly harder to come by.
- Extreme weather events made more frequent and intense by climate change, including heat waves and torrential rain, threaten the four main shellfish species harvested in the region, and with them, the tradition that has been passed down through generations of women.

Indonesia must integrate marine protection with fisheries subsidies, study says
- Indonesia must integrate marine protection measures into its subsidies for small-scale fishers, according to a new study.
- Despite claiming exemption from the 2022 WTO agreement to halt harmful fisheries subsidies, Indonesia needs a strategy to support small-scale fisheries and ensure marine sustainability.
- The government provides various supports, including insurance and fuel subsidies, and has made efforts to protect marine resources and boost fish stocks.
- The study suggests these subsidies should continue, as they are crucial for small-scale fishers’ livelihoods, while also enforcing marine conservation measures.

New approach to restore coral reefs on mass scale kicks off in Hawai‘i
- ʻĀkoʻakoʻa is a recently launched program aiming to restore a 193-kilometer (120-mile) stretch of coral reef along the west coast of Hawai‘i Island — one of the first to attempt restoration at a large scale.
- The project will identify individual corals with high thermal tolerance and other high-performance traits, then use them to breed genetically resilient coral larvae for release onto the reefs during natural spawning periods.
- ʻĀkoʻakoʻa is working with partners to reduce other stressors to the reefs, which can help corals be more resilient to rising sea temperatures, and drawing on Hawaiian traditional values of environmental stewardship.
- If successful, the project could provide knowledge for how to restore ailing reefs around the world suffering from an onslaught of human-driven thermal stress.

Indonesia’s Avatar sea nomads enact Indigenous rules to protect octopus
- For generations the Bajo sea nomads from Indonesia’s Sulawesi region have relied on catching octopus to meet their economic and nutritional needs.
- However, in recent years catch volumes have declined and locals worry that overfishing and increasingly extreme weather threaten livelihoods providing for hundreds of families.
- In response the community began enacting seasonal limits in late 2022, closing the fishery for months at a time and imposing minimum weight restrictions on octopus that can be collected during the fishing season.
- Anecdotal testimony from fishers Mongabay Indonesia spoke with suggests income growth resulting from the policy has outpaced the regional minimum wage.

Using immersive media to strengthen support for the environment: An interview with Wendy Schmidt
- Wendy Schmidt, co-founder of a constellation of philanthropic initiatives, uses “systems thinking” to address ecological, social, and economic issues. She leverages her background as an interior designer and journalist to focus on sustainability and communications.

Ghost nets haunt marine life in Malaysian marine park, study finds
- Ghost nets are lost or abandoned fishing nets that can take centuries to break down. In the meantime, they can damage delicate marine ecosystems and entangle and kill wildlife.
- In 2015, a local NGO started training volunteers to remove ghost nets washed up on the coral reefs and beaches of Tioman Island in Malaysia. The NGO also set up a hotline where anyone can report a ghost net sighting.
- From 2016-22, the volunteers retrieved a total of 145 ghost nets weighing 21 metric tons from Tioman Island’s waters. Analyzing data from these retrievals, a new study identified a spike in ghost nets during the COVID-19 pandemic.
- The authors call for better enforcement of laws against illegal fishing, tighter regulation of the buying and selling of nets, and more convenient ways for fishers to dispose of nets that are no longer useful.

Efforts to save Cambodia’s coast tread water as fish stocks plummet
- Along the coast of Cambodia, illegal fishing is driving fish stocks toward collapse and fishing communities into poverty.
- The Cambodian government’s capacity for and will to counter fisheries problems are minimal, and several government fisheries reform efforts are off track or behind schedule.
- As one multimillion-dollar foreign project to bolster government capacity and revive Cambodian fish stocks comes to an end, another is just kicking off.
- Whether these efforts to salvage Cambodia’s coastal resources will pay off depends on a range of factors and actors, but so far the plans implemented haven’t been enough to stave off the impending collapse of marine fish stocks.

Report: Illegal fishing and labor abuse rampant in China’s Indian Ocean fleet
- A recent report by the Environmental Justice Foundation (EJF) shows that the Chinese distant-water fleet is participating in illegal, unreported and unregulated (IUU) fishing and exploitative practices such as shark finning and human rights violations in the Southwest Indian Ocean.
- The report also suggests that Chinese investment in the blue economy in the Southwest Indian Ocean region could contribute to these problems by obligating indebted states to grant fishing rights to Chinese vessels.
- China has previously stated that it has a “zero-tolerance” approach to illegal fishing activities by its distant-water fleet, but evidence suggests that China isn’t taking adequate action to stop these issues.
- At the recent meeting of the Indian Ocean Tuna Commission (IOTC), China tried to introduce a proposal that would limit scrutiny of its distant-water fleet, but this was rejected by other parties to the commission — a move that founder and CEO of EJF called a “big win” in the ongoing work to document illegal fishing activities.

On a remote island, Honduras plans mega-prison in an unstudied reserve
- To address the country’s ongoing security crisis, Honduras is preparing the construction of a maximum-security prison on the uninhabited Islas del Cisne (Swan Islands), part of a protected archipelago.
- Because the three-island archipelago is so far from mainland Honduras, it has a unique ecosystem yet to be completely studied.
- The prison is set to begin construction later this year even as environmentalists speak out about the archipelago’s rich biodiversity.

Restoring Indigenous aquaculture heals both ecosystems and communities in Hawai‘i
- The loko i’a system of native fishponds in Hawai‘i has for generations provided sustenance to Indigenous communities, supported fish populations in surrounding waters, and generally improved water quality.
- These benefits, long understood by native Hawaiians, have now been supported by scientists in a new study that looked at the restoration of one such fishpond.
- Unlike commercial fish farms, loko i‘a thrive without feed input and need little management once established — aspects that highlight the holistic thinking and values-based management behind them.
- The study authors say the finding is another step toward communicating Indigenous knowledge to support governmental decision-making, part of wider efforts across the archipelago to weave Indigenous and Western ways of knowing to heal both ecosystems and communities.

Indonesian fishers mount a community-led fight against destructive fishing
- In coastal communities across Indonesia, local fishers are pushing back against destructive and illegal fishing methods by organizing into volunteer patrol groups known as Pokmaswas.
- These groups have become crucial in protecting Indonesia’s vast marine resources amid limited government resources and infrastructure.
- In recognition of their importance, the government has increased financial support for Pokmaswas and aims to strengthen these community-run surveillance networks further.
- Mongabay Indonesia met with members of two groups, one on the island of Sulawesi and the other on Lombok, to find out the shared challenges they face, the role they play as educators, and their use of social media to promote their mission.

Fishers left with no land, no fish, in fire sale of Cambodian coast
- Coastal communities in Cambodia are facing a double threat, from land and sea, as developers evict them from their homes and farms, and trawlers encroach on their nearshore fishing grounds.
- Illegal fishing, chiefly embodied by rampant, unchecked trawling in protected and prohibited waters, has devastated fish stocks, trashed marine ecosystems and left coastal communities in dire poverty.
- At the same time, the land is being sold out from under them: Nearly half of Cambodia’s coast has been privatized since 2000, with a slew of new projects tied to politically connected wealthy investors announced in the last five years, displacing families and closing off access to the sea.
- This is the second part of a Mongabay series about challenges faced by Cambodia’s small-scale fishers along the coast.

Peru approves the creation of long-awaited marine protected area
- Experts have called the creation of the Grau Tropical Sea National Reserve, which took more than 10 years to be approved, a milestone as it is rich in biodiversity.
- Observers expect the reserve to allow for greater control and monitoring of the area to prevent illegal fishing.
- However, some industrial fishing, including trawling, is permitted in the new reserve, a decision criticized by marine conservation experts who say Peru needs “no-fishing areas.”

Thai plan to relax fishing law stokes fear of return to illegal catches, worker abuse
- Thai lawmakers are discussing fisheries reforms that observers say risk undoing eight years of hard-won progress on human rights and ocean protection.
- Many of the proposed changes would amend reforms introduced nearly a decade ago following investigations that exposed rampant IUU fishing and associated worker abuses among Thailand’s infamous fishing fleets.
- Commercial fisheries representatives say the reforms are necessary to remove bureaucratic complexities and unfair penalties they claim have harmed the industry’s profitability since measures were introduced to address IUU and labor abuses.
- Some artisanal fishers and other observers say the proposed reforms would take Thailand in the wrong direction at a time when policymakers should be bolstering the country’s global reputation as a source of legal and sustainably caught seafood and protecting its resources and communities against the impacts of climate change.

Bottom trawling in U.K.’s marine reserves, legally, is apparently a thing
- In 2023, commercial fishing vessels spent more than 33,000 hours operating in the U.K.’s offshore marine protected areas, mainly using trawling and dredging methods.
- Bottom trawling is permitted in most of the U.K.’s MPAs, raising questions about the effectiveness of these protections. This issue isn’t exclusive to the U.K., but also occurs throughout the European Union.
- While the U.K. government says it has made “significant progress” it protecting its marine environment through the strengthening of its MPAs, conservationists say significant work is needed to protect the sensitive marine areas in the U.K.
- According to one expert, poorly managed marine protected areas render these ecosystems less resilient to the impacts of climate change and other stressors.

In Belize, flawed conservation measures threaten small-scale fishers’ livelihoods (commentary)
- The Mesoamerican Reef stretches roughly 1,000 kilometers along the coastlines of Mexico, Honduras, Belize and Guatemala, and is an integral part of people’s livelihoods across the region.
- Belize in particular has garnered much praise for its conservation policies on the reef, which often include creation of new marine protected areas, but local fishing communities increasingly feel left out of such decisions.
- “If Belize is to live up to its image of a conservation-forward country and blue economy maven, both fisheries and marine protected areas management decisions must be made based on sound scientific advice and on the feedback of the communities,” a new op-ed says.
- This post is a commentary, the views expressed are those of the author, not necessarily Mongabay.

Illegal fishing and land grabs push Cambodian coastal communities to the brink
Trawlers docked outside the port city of Sihanoukville, Cambodia. Screenshot from ‘Illegal fishing and land grabs push Cambodian coastal communities to the brink’ by Andy Ball / Mongabay.KOH KONG, Cambodia — Join Mongabay staff writer Gerry Flynn as he embarks on a crucial investigation along Cambodia’s coast, uncovering the effects of illegal fishing and unchecked coastal development on local communities. In recent years, fish stocks in Cambodian waters have plummeted, leading to a dramatic decline in income for small-scale fishers. The primary culprits? […]
Small-scale fishers lose out to trawlers in race to catch Cambodia’s last fish
- On Cambodia’s coast, fish catches have dropped precipitously in recent years, and so have small-scale fishers’ incomes.
- Small-scale fishers say commercial trawlers have been illegally entering their fishing grounds, scraping the sea clean of life and, with it, their community’s ability to survive.
- Although fishers often blame foreign vessels, satellite data show Cambodian-, Thai- and Vietnamese-flagged trawlers making frequent illegal incursions into Cambodia’s protected waters, community fisheries or shallow inshore waters legally reserved for small-scale fishers.
- This is the first part of a Mongabay series about challenges faced by Cambodia’s small-scale fishers along the coast.

As catches fall, Sierra Leone’s artisanal fishers turn to destructive practices
- Sierra Leone’s fish stocks have been under severe strain in recent years due to intensive industrial fishing and a growing population of artisanal fishers, with fishers consistently reporting falling catches.
- This has triggered heightened competition for increasingly scarce yields.
- To secure their livelihoods, artisanal fishers have turned to unsustainable fishing gear, such as undersize-mesh nets, and target fish breeding and nursery grounds, disrupting the fish reproductive cycle.
- The crisis is fueled by the ready availability of illegal nets, weak law enforcement and widespread economic hardship.

Otter-preneurs: Female sea otters lead the way in tool use for survival
- In Monterey Bay, California, southern sea otters face food scarcity as their preferred prey, urchins and abalone, have declined due to climate change, overfishing and other environmental factors.
- To adapt, some sea otters, particularly females, use tools like rocks, shells and even discarded glass bottles to crack open harder-shelled alternative prey like snails, clams and mussels.
- A study of 196 tagged sea otters found that frequent tool users, especially females, could consume prey up to 35% harder than non-tool users and had significantly less tooth damage.
- The findings highlight the importance of behavioral flexibility in the face of ecological challenges and underscore the need to protect the threatened southern sea otter population, which plays a crucial role in maintaining the balance of coastal ecosystems.

18 years on, how are sharks faring in French Polynesia’s shark sanctuary?
- While sharks are feared and threatened in many parts of the world, French Polynesia decided to protect them two decades ago by declaring its entire exclusive economic zone a massive sanctuary for sharks and rays.
- The move aligns with traditional beliefs that hold sharks as sacred animals that represent gods and the link between past and present.
- New citizen-science data offer some evidence the sanctuary is working to protect sharks, but more research is needed to confirm it.
- Sharks still face threats there from accidental bycatch and illegal fishing, and some conflicts with local fishers have emerged.

Fishers decry ‘underhanded’ new initiative to protect Mexico’s vaquita
- Over the past two years, the Mexican Navy has installed hundreds of anti-trawling hooks to prevent vaquitas being caught in illegal gill nets in the Upper Gulf of California.
- The long hooks, attached to concrete blocks, are designed to snag the gill nets that target totoaba fish, but which have become notorious for driving the vaquita porpoise to the brink of extinction.
- The project was initially credited with an immediate drop in illegal fishing boats in the vaquita’s core habitat, but fishers from the community of San Felipe say new blocks were installed without warning outside the core habitat, snagging more of their equipment and creating ghost nets that could harm vaquitas.
- Results from the latest vaquita population survey are expected in June; last year, scientists said as few as 10 of the critically endangered porpoises may still be alive.

No mercy for overfished yellowfin tuna at Indian Ocean fisheries meeting
- Members of the Indian Ocean Tuna Commission, the intergovernmental body that regulates fishing for tuna and tuna-like species in the region, met May 13-17 in Bangkok.
- Although a decision on reining in catches of yellowfin tuna (Thunnus albacares), which has been declared overfished for the past nine years, was perhaps the most anticipated move of the meeting, delegates failed to reach any such agreement.
- They did, however, strengthen management of skipjack tuna (Katsuwonus pelamis) and swordfish (Xiphias gladius) fisheries, and took steps to rein in fish aggregating devices (FADs), which are criticized for netting large numbers of juvenile tuna and nontarget species, and for polluting the ocean with large amounts of lost fishing gear.

Indonesian activist freed in hate speech case after flagging illegal shrimp farms
- Indonesian environmental activist Daniel Frits Maurits Tangkilisan has had his sentence overturned on appeal, in a case that saw him charged over a Facebook post highlighting illegal shrimp farms operating in a marine protected area.
- The appeals court held that while the post constituted hate speech, as a lower court had ruled, it was made in defense of the constitutional right to a healthy environment.
- Three fellow activists face prosecution under the same charges for posting a video of their opposition to the polluting shrimp farms in Karimunjawa National Park, an ostensibly protected area.
- The case is one of hundreds prosecuted under the widely panned online speech law that activists and rights experts say has been exploited by the state and business interests to silence critics.

To renew or not to renew? African nations reconsider EU fishing deals
- The European Union currently has fisheries access deals with 11 African countries, several of which are up for renegotiation this year.
- Under the deals, called Sustainable Fisheries Partnership Agreements (SFPAs), European fishing companies gain access to resource-filled foreign waters, while the African countries get cash.
- Senegal was the first country to sign such a deal, in 1979, but President Bassirou Diomaye Faye was elected in March after proposing to suspend it altogether in response to concerns that it’s unfair to local fishers. It’s not yet clear whether he will follow through, but his rhetoric reflects shifting arrangements in African fisheries, where the EU no longer dominates as it once did.
- Experts see this as a possible win for local control of precious marine resources, but they also caution that many of the alternative arrangements African governments are turning to instead of SFPAs are more socially and environmentally problematic, and less transparent.

Undercover in a shark fin trafficking ring: Interview with wildlife crime fighter Andrea Crosta
- Worldwide, many of the key players in wildlife trafficking are also involved in other criminal enterprises, from drug smuggling to human trafficking and money laundering.
- In an interview with Mongabay, Andrea Crosta, founder of Earth League International, talks about the group’s new report on shark fin trafficking from Latin America to East Asia and the concept of “crime convergence.”
- International wildlife trafficking, including the illegal trade in shark fins, is dominated by Chinese nationals, Crosta says.
- Since smuggling routes often overlap and criminal groups frequently work together across borders, Crosta calls for field collaboration among countries and law enforcement agencies to fight wildlife crime, the world’s fourth-largest criminal enterprise.

Twilight zone fishing: Can we fish the ocean’s mesopelagic layer?
- Fishing experts are looking for ways to fish in the mesopelagic zone, a layer of water that stretches from 200-1,000 meters (660-3,300 feet) beneath the surface, which has, thus far, remained relatively unexploited.
- Many challenges stand in the way of making mesopelagic fishing a reality, such as the difficulties of finding and capturing mesopelagic fish, and processing them into usable products.
- Yet experts are working to overcome these obstacles, with one suggesting that mesopelagic fishing could begin in the next few years.
- Conservation experts have expressed concern about the possible start of mesopelagic fishing, arguing that it could cause environmental problems.

As plastic talks wrap up in Canada, fishers in Indonesia count the costs
- Fishers in the Thousand Islands archipelago off the Jakarta coast have reported extensive economic losses due to the scale of plastic waste littering their seas.
- Declining catch volume and costly repairs to boat engines are cited as drags on productivity, with one fisher telling Mongabay that his family now earns less than a decade earlier.
- Negotiators convened by the U.N. hope to conclude an international agreement in November that would limit the hundreds of millions of tons of plastic produced around the world each year.

Indonesia resumes lobster larvae exports despite sustainability, trade concerns
- The Indonesian government will resume a controversial policy of exporting lobster larvae, initially just to Vietnam, in exchange for investment in its own lobster-farming industry.
- The ban has met with controversy since it was introduced in 2016; a subsequent attempt to lift it failed after the fisheries minister at the time was arrested for taking bribes to issue export permits.
- The current minister says the lifting this time around is based on pragmatic considerations, with law enforcement efforts failing to stop the smuggling of lobster larvae.
- Critics say the move will benefit Vietnam more than it will Indonesia, given that the former’s far more advanced lobster-farming industry generates far more value from the sale of mature lobsters than Indonesia ever could from the sale of larvae.

‘Our life support system is at risk’: Interview with ‘Her Deepness’ Sylvia Earle
- At the 9th Our Ocean Conference in Athens, Mongabay’s Elizabeth Claire Alberts interviewed oceanographer and marine biologist Sylvia Earle about the pressures facing our oceans, actions needed to turn things around, and how to find hope for the future.
- Earle has been a trailblazer in her career as a scientist, with more than 225 publications to her name, leading more than 100 expeditions, and breaking records as the first woman to venture into the deep ocean in a submersible and also to perform the deepest untethered sea walk.
- She’s currently president and chair of the NGO Mission Blue and an explorer-in-residence at the National Geographic Society.
- Now in her late 80s, she still spends most of her time traveling the world to inspire action to protect the ocean.

No answers for Ghanaian fishery observer’s family months after suspected death
- Samuel Abayateye, a 38-year-old father of two, was working as a fisheries observer when he was reported missing from his assigned vessel in October 2023.
- After a body missing its head, forearms and feet that Abayateye’s family says closely resembled him washed ashore in December, the Ghana Police Service opened an investigation.
- Five months later, Abayateye’s family said they still haven’t received any information from the authorities investigating the case, or the results of a DNA test to confirm the identity of the body.
- A fisheries observer told Mongabay the case has sown fear among observers appointed to monitor and report on illegal fishing in fleets operating in Ghana. Fishing industry experts say the case highlights the dangers faced by observers, whose job is critical to ensuring fishing vessels comply with the law.

Who was Samuel Abayateye, the fishery observer missing in Ghana
ANYAMAM, Ghana — In October 2023, Samuel Abayateye, a 38-year-old fishery observer, went missing in Ghana. This unsettling event is part of a troubling pattern, as disappearances of fishery observers in Ghanaian waters have occurred before. In this video, Mongabay travels to Anyamam, Samuel’s home village, to speak with his family and uncover more about […]
Fewer fish and more rules lead to illegal catches, Italian fishers say
- The line between legal and illegal fishing in the waters off Italy’s Calabria region is often blurred, with fishers blaming stringent top-down regulations for constricting their traditional practices.
- The issue is further muddied by the presence here of the ‘ndrangheta or Calabrian mafia, which investigations have shown is involved in the fish trade and also uses it as cover for illicit activities such as drug smuggling.
- The Mediterranean Sea is experiencing a decline in fish stocks, ranging from 60-90% depending on the species, with the NGO Sea Shepherd Italia blaming illegal fishing for environmental damage.
