Sweeping cuts and deregulation imperil U.S. fisheries, experts warn
- The United States has long had one of the best systems of fisheries management in the world, supporting 2.3 million jobs and a relatively high number of healthy fish populations.
- The Trump administration is enacting sharp cuts to the budget, staff and facilities of the agency that manages U.S. fisheries, the National Oceanic and Atmospheric Administration (NOAA), and on April 17 ordered widespread deregulation of fisheries.
- The administration says the changes are necessary to reduce government waste and fraud, save taxpayer money, create jobs and enhance profitability, but experts and former NOAA employees told Mongabay these moves have been poorly planned and will be “devastating” for U.S. fisheries.
- The staff cuts, regulatory changes and facilities downsizing are not easy for the public to track, raising questions about the transparency of the Trump administration’s moves.
15 years after the BP oil spill disaster, how is the Gulf of Mexico faring?
- The Deepwater Horizon disaster on April 20, 2010, was the largest offshore oil spill in U.S. history, releasing an estimated 4.9 million barrels of oil into the Gulf of Mexico over nearly three months.
- Fifteen years later, the gulf ecosystem shows a complicated picture of both resilience and lingering damage, with some species, like brown pelicans, recovering, while others, like humans, dolphins and deep-sea corals, continue to struggle with long-term health impacts.
- The disaster prompted an unprecedented legal settlement directing billions toward restoration projects, though experts debate whether these funds have been used effectively for ecosystem-scale recovery.
- Climate change remains the “800-pound gorilla in the room,” threatening the gulf’s future resilience, one expert said, with others warning that continued pressure from fossil fuel development, agricultural runoff and other threats could push the system beyond its capacity to recover.
Mangroves mount a fragile green revival in Iraq’s toxic south
- Sea-level rise and upstream damming have worsened saltwater intrusion in the Shatt al-Arab River, pushing brine deep into Iraq’s interior and threatening agriculture, fishing and marshland ecosystems.
- A mangrove-planting project has been launched as a nature-based solution to combat coastal erosion, saltwater intrusion and pollution — threats that not only endanger Basra’s coastline but also the freshwater marshlands farther inland.
- Despite scientific backing and community support, the project faces significant obstacles like untreated sewage and industrial waste, while limited government support further hampers the project’s long-term viability and impact.
Vital Mekong fish corridors tracked for first time, but funding cuts threaten future research
- By implanting fish with small electronic transmitters, researchers were able to track key migration corridors in the Mekong River.
- The findings underscore the threat that dozens of planned dams along the Mekong will cut off these vital migratory paths.
- The study, which the lead author describes as a “pilot effort,” was funded by USAID; the funding gap caused by the U.S. foreign aid freeze leaves the future of such research in question.
Trump opens massive marine protected area to commercial fishing
U.S. President Donald Trump has signed a proclamation allowing commercial fishing in Pacific Islands Heritage Marine National Monument (PIH), a massive marine protected area home to threatened fish, sea turtles and marine mammals. The proclamation says U.S.-flagged vessels may now fish within 50-200 nautical miles (90-370 kilometers) inside PIH’s boundaries. While the proclamation and factsheet […]
In an ancient Javanese sultanate, coastal women battle climate fallout
- The coast of Demak district, the site of the first Islamic sultanate on the island of Java, has been inundated by the sea over decades owing to groundwater extraction and development.
- The erosion of human settlements is likely introducing new risks for women: “Our conclusion is that women and children, as well as poor families, including the elderly and disabled, are the most vulnerable,” a local legal aid nonprofit told Mongabay.
- Globally, around 90% of fish species are either fully exploited or overfished, and climate change is set to worsen the crisis by disrupting fish reproduction as oceans warm and acidify.
Fishing rights, and wrongs, cast small-scale South African fishers adrift
- A community of mixed-race families has lived and fished in South Africa’s Langebaan Lagoon since the 1800s.
- Starting with the former apartheid government in the 1970s, a series of conservation-oriented decisions ostensibly aimed at protecting fish stocks have slowly squeezed the number of these fishers allowed to operate in the lagoon.
- The government now says fish stocks have collapsed and it has reduced the number of small-scale fishers operating in the lagoon even further, while allowing recreational fishing to continue unimpeded. For their part, the fishers deny the stocks have collapsed, and blame declining catches on industrial developments.
- One expert likened the three-decade-long exclusion of the Langebaan net fishers to a case of fortress conservation, in which local people are squeezed out of nature and denied access to resources they’ve long used in order to preserve them for elites.
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.
Seychelles becomes first country to comply with fisheries transparency standard
- Seychelles, an archipelagic nation off the eastern coast of Africa, has become the first country to comply with the Fisheries Transparency Initiative (FiTI) standard that lays down what information about a country’s fisheries sector should be published online by public authorities.
- When it committed in 2016 to becoming FiTI-compliant, Seychelles signed up to provide complete and up-to-date information on its fisheries sector that would be useful not just to policymakers but also to civil society organizations and the public.
- Seychelles’ FiTI-compliant status signals marked improvements in data availability, but it doesn’t guarantee that all the information on the fisheries sector is complete and fully accessible, with experts pointing out that some critical gaps remain.
- For example, fishing access agreements struck between the Seychelles and other governments, industry associations and private companies are now available online, but critics say decision-makers remain unable to evaluate them fully.
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.
As Acapulco’s mangroves disappear, Mexico takes strides to protect its coastal forests
- One of Acapulco’s lagoons has experienced the near-complete loss of its mangroves due to urbanization and hurricanes.
- Another Acapulco lagoon has also lost portions of its mangroves, affecting the local fishing industry.
- Overall, the Mexican state of Guerrero has lost more than half of its mangroves since 1979.
- Mexico’s government is working with international organizations, scientists and local communities to restore the country’s lost mangroves.
Peruvian fishers sue for additional compensation after big December oil spill
- On Dec. 22, 2024, a pipeline leak at the New Talara Refinery in northern Peru spilled oil into the Pacific Ocean, coating 10 kilometers (6 miles) of coastline in black.
- Three days later, the Peruvian environment ministry declared a 90-day environmental emergency, paralyzing tourism and work for more than 4,000 artisanal fishers.
- Now, more than three months later, the fishers have returned to work on a sea dominated by the oil industry. They say the compensation they received from the refinery owner, state-owned oil company Petroperú, is insufficient and they are seeking more.
- For its part, the company says it has met its commitments.
‘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.
Australia’s environment minister sued for failure to act on threatened species
Australian conservation NGO The Wilderness Society has launched a court case against the country’s environment minister, Tanya Plibersek, alleging her failure to put in place formal recovery plans for a number of threatened species. The public interest legal organization Environmental Justice Australia recently announced that its lawyers are representing The Wilderness Society in the federal […]
In Pakistan, sea level rise & displacement follow fisherfolk wherever they go
- Rising sea levels are displacing fisherfolk in Pakistan’s coastal areas, forcing them to move to higher ground, such as Karachi, where they now face saltwater intrusion and other climate impacts.
- For many, this displacement is not just about losing homes, but also cultural heritage, traditions and livelihoods, with women, in particular, losing economic freedom as fishing communities decline.
- The Pakistani government lacks a formal policy for the voluntary migration of climate refugees, and while efforts like mangrove restoration have been attempted, they have not significantly alleviated the fishing community’s problems.
- Karachi is projected to receive 2.3 million climate migrants by 2050, primarily due to rising sea levels, saltwater intrusion, and other climate-related catastrophes.
Panama conducts large illegal fishing bust in protected Pacific waters
- Panamanian authorities seized six longliner vessels on Jan. 20 for fishing illegally in protected waters. They also opened an investigation into an additional 10 vessels that surveillance data showed had apparently been fishing in the area but left by the time authorities arrived.
- The seizures took place in the Cordillera de Coiba, a marine protected area that’s part of the Eastern Tropical Pacific Marine Corridor, which connects several MPAs in four countries. It was the largest illegal fishing bust in the history of Panama’s MPAs.
- The vessels, whose activity is still under investigation, were Panamanian-flagged, meaning they were registered in the country, but the identity and nationality of the owners isn’t clear.
- The surveillance work in the case was done in part through Skylight, an AI-powered fisheries intelligence platform, and was supported by a group of fisheries monitoring nonprofits.
Researchers find new killifish species in Kenya
- According to a new study, a new species of killifish, Nothobranchius sylvaticus, has been found in seasonal swamps in the ephemeral marshes of Kenya’s historic Gongoni Forest at the coast.
- Scientists from Canada, France, Kenya and South Africa report that the severely restricted habitat of the seasonal Mkurumudzi River in southeastern coastal Kenya is threatening the survival of the fish species.
- The killifish, a unique species with iridescent blue scales, red markings and vibrant fins, has been deposited at the National Museums of Kenya and the Royal Museum for Central Africa.
- An expert is calling for the formal designation of the Gongoni Forest as a key biodiversity area and local communities’ engagement to protect the small freshwater fish, ensuring its recovery and avoiding threats.
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.
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.
Sumatran culinary heritage at risk as environment changes around Silk Road river
- Research shows that landscape changes across the Musi River Basin in Indonesia’s South Sumatra province risks food security across the river delta as fish stocks diminish and protein availability declines, including in the provincial capital, Palembang.
- Some fish traders and artisans in the city of 1.8 million worry culinary culture in Palembang is becoming endangered as rising sedimentation in the Musi River threatens the freshwater snakehead murrel fish.
- Reporting in March, during the fasting month of Ramadan, showed prices of food staples made from this fish increasing sharply from previous months as demand surged for fast-breaking events.
Conservationists, fishing industry find balance on protecting African penguins
Conservation NGOs and commercial sardine and anchovy fisheries in South Africa have reached an out-of-court settlement agreeing to extents of fishing closures around six key African penguin breeding colonies. The agreement, endorsed by the environment minister, was made a court order on March 18. The boundaries of the new fishing closures achieve “the sweet spot […]
Fish-tracking robot aims to make fishing more sustainable in developing nations
- Israeli scientists have developed a solar-powered underwater robot called SOUND that can roam autonomously for five days at a stretch, counting fish and communicating its findings back to observers onshore.
- The goal is to help local fishers in developing countries understand their fish populations so they can avoid overfishing and the capture of unwanted species.
- They tested the system in Malawi, among other locations, where fishers are facing a myriad of problems related to uncontrolled fishing.
Rep from American Samoa calls for opening protected Pacific waters to tuna fishing
- U.S. Congresswoman Amata Radewagen, who represents American Samoa, has urged the Trump administration to reopen most of Pacific Islands Heritage (PIH) Marine National Monument, a vast protected area in the Central Pacific Ocean, to industrial tuna fishing.
- Radewagen’s request came in a letter to President Donald Trump dated Jan. 23. It was accompanied by a background document that called for an executive order opening all Pacific marine national monuments and national marine sanctuaries to tuna fishing.
- Conservationists sharply criticized Radewagen’s move, while a tuna trade group supported it.
- Some details of the letter and background document, which Radewagen’s office shared with Mongabay, have not previously been publicly reported.
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.
Gas leak from BP platform off West Africa worries fishermen, environmentalists
In January, U.K. oil giant BP announced it had started producing gas from the Greater Tortue Ahmeyim (GTA) project, a natural gas production platform it operates off the coast of Mauritania and Senegal. A month later, Mauritanian media reported that a gas leak had been detected at one of the wells. In a statement shared […]
To save a Honduran reef, locals craft custom gear and hunt invasive lionfish
Without a natural predator, invasive lionfish, which damage coral reefs, have become widespread throughout the Caribbean over the last several decades. To prevent further harm off the northern coast of Honduras, locals have resorted to crafting their own spears to effectively and safely hunt lionfish, reports Mongabay contributor Fritz Pinnow. Julio San Martín Chicas, program […]
Fishing cat home range far bigger than previously thought, Nepal study suggests
- A GPS-collaring study in southeastern Nepal found that fishing cats could have much larger home ranges than previously recorded.
- Contrary to popular belief among local communities, some fishing cats were found to inhabit human-dominated landscapes, rather than only visiting them at night.
- Researchers suggest that low prey density in Nepal’s Koshi Tappu Wildlife Reserve and more accurate GPS tracking may explain the larger home ranges observed.
- The study highlights the need for community engagement in conservation, as fishing cats help control rodent populations and face threats from habitat loss and human-wildlife conflict.
Liberia to start industrial shrimp fishing, worrying artisanal fishers
- Liberia plans to expand industrial bottom trawling in the country by authorizing a new fishery for high-value shrimp.
- However, the government has released few details about the plan, including how much shrimp it will allow the new fishery to exploit, when the trawling would begin, or how it would be regulated.
- The country’s umbrella organization for artisanal fishers casts the move as a threat to the livelihoods, safety and food security of Liberia’s more than 57,000 artisanal fishers, as well as to the country’s marine life.
From Kenya to Madagascar, massive effort aims to put seagrasses on the map
In 2019, scientists set out to map the extent of seagrass in Seychelles, an island nation off the eastern coast of Africa. There, they hit upon a startling number: More than 90% of the country’s “blue carbon,” or the carbon stored in marine ecosystems, is contained within seagrass meadows. Under the Large-scale Seagrass Mapping and […]
Illegal sea fence displaces fishers and sparks land scandal near Jakarta
- A property developer installed 30 kilometers (19 miles) of bamboo fencing in the sea near Jakarta, blocking fishers’ access; an investigation revealed it encompassed 280 ocean plots for which title deeds had been illegally issued.
- The fence has forced many fishers to stop working, while coastal farmers have lost their land to the same luxury development; residents also face eviction with no clear alternatives.
- Authorities have sanctioned a handful of individuals from the public and private sectors and started revoking the illegal deeds, but activists are demanding criminal prosecutions against the companies responsible.
- The case highlights weak oversight of Indonesia’s national strategic projects, raising concerns over environmental destruction, loss of livelihoods, and government favoritism toward big developers.
India’s fisherwomen getting left behind by blue economy policies
Women make up nearly half of India’s marine fisheries workforce, yet policies to strengthen the country’s blue economy are leaving women behind, reports contributor Priyamvada Kowshik for Mongabay India. India’s draft blue economy policy framework aims to significantly boost the contribution of marine resources to the country’s GDP, and at the same time improve the […]
Thailand’s last sea nomads confront a changing world
MU KOH SURIN, Thailand — Ngui slips beneath the waves, his movements effortless and precise. He’s done this thousands of times, diving deep to find fish and crustaceans hiding beneath the coral shelves of the Andaman Sea. His catch today is different. A sheet of black plastic, snagged on a rock 50 kilometers (30 miles) […]
Endemic fish wiped out in Brazilian Amazon hydroelectric dam area, study finds
- The construction of the Balbina hydroelectric dam in the Brazilian Amazon led to the loss of seven endemic fish species in the Uatumã River, researchers have found.
- The hydroelectric dam has transformed the Uatumã River’s fast-flowing habitats into static environments, making them unsuitable for certain fish species.
- Researchers call for the investigation of unaffected tributaries, such as the Jatapu River, as possible refuges for the missing species and future conservation efforts.
- The study underscores the broader threat of hydropower dams and other environmental stressors, like industrial fishing and climate change, to Amazonian fish populations.
Illegal seabed dredging surges as Indonesia resumes sand exports
- Reports of unauthorized seabed dredging have surged following Indonesia’s decision to resume sea sand exports in 2023, raising environmental concerns and exposing weak marine law enforcement.
- Officials argue that removing sediment helps ocean health and prevents land buildup, but experts and activists warn the policy contradicts marine conservation efforts and lacks transparency.
- Dredging threatens mangroves, coral reefs, and fish populations, with projected losses to fishing communities far outweighing state revenue and corporate profits.
- Experts urge the government to reinstate the export ban, conduct thorough environmental impact assessments, and allocate funds for ecological restoration and affected communities.
Small-scale fishers’ role in feeding the planet goes overlooked: Study
- A new study found that small-scale fishing accounts for at least 40% of catch worldwide and provides employment for 60 million people, more than a third of whom are women.
- Small-scale fishing could provide a significant proportion of the micronutrient intake for the 2.3 billion people on Earth who live near coastlines or inland bodies of water, the study found.
- More than 60% of small-scale fishing catch in the studied countries came from places where small-scale fishers had no formal rights to participate in management and decision-making processes.
- “We wanted to have a paper that provided key findings at the global level for each of these dimensions, so that it will be clear for governments that small-scale fishing cannot continue to be overlooked in terms of policymaking,” one of the study authors told Mongabay.
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.
Study finds population crash for critically endangered European eel in Spain’s Ebro Delta
The critically endangered European eel population is facing collapse in Spain’s Ebro Delta, where populations have plummeted by more than 80% in recent years, according to a new study. The study’s authors warn this decline may be as severe, or worse, than the crash of the late 1970s and early 1980s when overfishing pushed the […]
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.
Researchers find microplastics for the first time in the Finnish Sámi waters
- Scientists and Indigenous Skolt Sámi knowledge holders have detected microplastics in the lakes and rivers that the Indigenous Sámi communities have used for generations.
- The concentration of microplastics was small, researchers found, but it was still higher than the quantity expected, given that the area is thought to be pristine.
- The average size of the microplastics was 100 micrometers and concentrations ranged from 45 to 423 microplastic particles per cubic meter.
- While the source of the microplastics is unknown, researchers say one of the sources could be from the transboundary pollution accumulated in fish that come from the ocean to the freshwaters for spawning.
Underwater volcano in Barents Sea reveals diverse marine life, study finds
What’s new: Following the discovery of the underwater Borealis Mud Volcano on the Arctic seabed in 2023, researchers have now confirmed that the methane-spewing volcano is home to a diverse array of marine life thriving in the unique habitat. What the study says: In 2023, scientists from UiT The Arctic University of Norway discovered the […]
As global genetic diversity declines, conservation efforts offer some hope
Genetic diversity within many species is declining globally, according to a recently published study. “Any threat that reduces the size of a population, or which causes a larger population to become fragmented into two or more smaller populations, can cause a loss of genetic diversity,” lead researcher Catherine Grueber, from the Conservation Genetics Specialist Group […]
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. The 48,000-square-kilometer (18,500-square-mile) marine sanctuary covers two of the country’s northernmost uninhabited atolls, Bikar and Bokak, and the surrounding deep sea, and it is the first federal marine […]
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.
The force is strong with new giant ‘Darth Vader’ sea bug found off Vietnam
What’s new: From the seafood markets of Vietnam, researchers have identified a species of giant crustacean or “sea bug” that’s new to science. They’ve named it Bathynomus vaderi, for its distinctly shaped head reminiscent of the helmet of Star Wars villain Darth Vader, according to a recently published study. What the study says: Bọ biển […]
Thai farmers demand action to restore ecosystems, compensate for invasive fish
- Citizens rallied in Bangkok this week demanding accountability and action from the government and private corporations following an outbreak of invasive fish that has ravaged Thailand’s freshwater ecosystems and aquaculture industry.
- Blackchin tilapia, an omnivorous species native to West Africa, is highly adaptable, breeds rapidly and is capable of outcompeting native wildlife and commercially farmed species, including shrimp.
- Thailand’s largest agricultural conglomerate has come under scrutiny because it obtained a permit to import the species in 2010, shortly before the first detections in the wild in the same province as its research facility.
- The activists urged the government to eradicate the species, compensate affected farmers and identity the parties responsible for the outbreak.
1 in 4 freshwater species worldwide at risk of extinction: Study
The most extensive global assessment of freshwater animals to date has revealed that a quarter of all freshwater animal species on the IUCN Red List are threatened with extinction. The largest number of these threatened species are found in East Africa’s Lake Victoria, South America’s Lake Titicaca, Sri Lanka’s Wet Zone, and India’s Western Ghats […]
2024’s top ocean news stories (commentary)
- Marine scientists and policy experts from nine international research and conservation institutions share their list of the top ocean news stories from 2024.
- Hopeful developments this past year include advancing innovations in mapping technologies, legal strategies and financial instruments to protect the ocean and greater inclusion of Indigenous peoples and coastal communities into high-level ocean planning.
- At the same time, 2024 was the hottest year on record as a result of climate change, surpassing 2023, and scientists declared the fourth global coral bleaching event, a major setback for the world’s coral reef ecosystems.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
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.
Campaigners celebrate as firm making first-ever GMO fish ceases operations
- AquaBounty Technologies, the first company in North America to get regulatory approval to sell a genetically engineered animal for human consumption — an Atlantic salmon spliced with genes from other fish — announced on Dec. 11 that it was closing its last facility, ceasing fish farming activities, and culling remaining stock.
- A coalition of conservation and Indigenous groups that had campaigned against AquaBounty celebrated the announcement, saying the company’s work posed environmental and public health risks.
- AquaBounty’s proponents contend that the salmon was completely safe and more sustainably produced than some farmed alternatives, and that decades-long campaigning against it had contributed to the company’s failure.
After trial and error, Mexican fishers find key to reforesting a mangrove haven
- David Borbón and his community are working to restore mangroves in a fishing village within Mexico’s El Vizcaíno Biosphere Reserve, one of the country’s largest protected areas.
- The mangroves act as a natural barrier, protecting the coastal community and ecosystems from hurricanes and other severe weather.
- Borbón, who wasn’t formally educated in any science, conducted a series of experiments to find the best method to reforest the area’s declining mangrove forests and settled on a direct sowing technique that replicates natural patterns.
- With the support of his family and community, he has now planted more than 1.8 million mangroves and largely facilitate the recovery of the mangrove ecosystem.
Pioneer expedition: new findings reveal the state of the Amazonian Rivers
AMAZON RIVER, Brazil – Those who have visited the Amazon know the importance that the rivers have to the local communities, whose livelihoods depend on them. They provide drinking and cooking water, abundant fishing opportunities, and vital transportation routes for people and goods. Simply put, the rivers are the heart of life in the Amazon. […]
‘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 […]
Shipbreaking pollutes Türkiye’s coast despite European cleanup efforts
- Over the past decade, more than 2,000 ships have been dismantled at shipyards in Türkiye’s coastal town of Aliağa, one of the world’s main destinations for decommissioned vessels.
- Locals and environmentalists alike complain of rampant water and air pollution linked to shipbreaking, among other industrial activities.
- Workers’ unions and activists have also called out substandard working conditions at the yards, recording 11 deadly accidents between 2018 and 2024.
- Efforts by the European Union to promote better practices in some yards by allowing them to dismantle European ships have had a mixed effect, according to workers and experts Mongabay interviewed, encouraging some yards to improve practices without solving the pollution problem.
‘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.
Greater Mekong serves up 234 new species in a year, from fanged hedgehog to diva viper
- Researchers and local nature enthusiasts described 234 new-to-science species across the Greater Mekong region in 2023.
- Among the new assortment of critters are sweet-smelling plants, glamorous snakes, a dragon lizard, a psychedelic-orange crocodile newt, and several new mammals, including a mole shrew and a fanged hedgehog.
- The Greater Mekong is a fast-developing region of Southeast Asia, characterized by intensive agriculture, internationally significant inland fisheries and rapid urban expansion.
- As such, the newly described species and their habitats are under pressure from multiple threats, not least from the illegal wildlife trade that also flourishes in the region. Experts say consistent and concerted action is required to secure their future.
Water returns to Amazon rivers amid historic drought
The Amazon River and its tributaries, which make up the largest freshwater basin in the world, are showing signs of recovery after dropping to record-low levels between September and November 2024. Abnormally low rainfall and high temperatures across the Amazon caused water levels to plummet, shutting down river transport, isolating communities and leaving industries without […]
Research vessel E/V Nautilus spots multiple nautiluses for the first time
The crew of the research vessel E/V Nautilus erupted in excited chatter as they watched live video from a remotely operated vehicle traversing the German Channel in the Pacific island state of Palau. “It’s finally happened!” someone could be heard saying as the camera on board the ROV Hercules zoomed in to reveal a lone […]
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 […]
First-of-its-kind crew welfare measure adopted at Pacific fisheries summit
- The organization that sets fishing rules for a swath of the Pacific Ocean covering nearly 20% of Earth’s surface and supplying half the world’s tuna catch held its annual meeting in Fiji from Nov. 28 to Dec. 3.
- Parties to the Western and Central Pacific Fisheries Commission (WCPFC) adopted a landmark crew welfare measure — the first binding labor rights measure adopted by any of the world’s 17 regional fisheries management organizations.
- The parties, 25 countries plus the European Union, also adopted a voluntary measure to implement electronic monitoring of catches.
- However, they didn’t adopt a proposal to curb potentially dodgy ship-to-ship transfers known as transshipments, or substantive new protections for sharks and seabirds, as NGO observers had hoped.
Construction of Indonesia’s new capital sees port activity crowd out fishers
- Construction of Indonesia’s vast new capital city on the east coast of Borneo has prompted a surge in port traffic in Balikpapan Bay, elevating existing pressures on the belt of mangroves lining the inlet.
- Local villages depend on near-shore fisheries within the inlet, but interviews indicate these communities are struggling to endure the increased port traffic and restrictions to fishing areas.
- District-level officials acknowledged that fishers face diverse challenges as a result of the new capital construction.
- However, they say they will seek redress for the destruction of any of the 16,000 hectares (39,500 acres) of mangroves in the bay area.
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.
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.
Women in Putumayo turn to fish farming and away from the coca industry
- A women-led fish farming initiative in Colombia’s Putumayo department offers an alternative to the coca economy, challenging both environmental damage and traditional gender roles.
- Wedged between the Ecuadorian border and the fringes of the Amazon, Putumayo has long been heavily affected by armed conflict and coca cultivation, resulting in high levels of violence and human rights abuses.
- The initiative empowers women, challenging traditional gender roles in rural Colombia by providing stable, legal income and reducing dependency on the dangerous coca economy.
- Financial constraints, limited government support, lack of infrastructure, as well as persistent threats from armed groups hinder the development of alternatives to coca farming.
‘Tragic’ mass fish die-off devastates Amazon River channel amid historic drought
A mass fish die-off in Brazil’s Amazon River region has killed an estimated 20-30 metric tons of fish and other aquatic animals, following one of the worst droughts in Amazonian history. On the night of Nov. 12, fishers from the riverine community of Igarapé do Costa, near the city of Santarém in northern Brazil, began […]
Researchers find high levels of mercury in Amazon’s Madeira River water & fish
- In a groundbreaking expedition, researchers from Harvard and Amazonas State University began monitoring water quality and mercury contamination in the Amazon Basin’s largest tributary.
- The Madeira River Basin has been heavily impacted by human actions, such as hydropower plants, deforestation and illegal gold mining, which degrade its ecosystems.
- Initial results from Harvard reveal high levels of mercury in the Madeira, although still below the limit recommended by Brazil’s authorities.
- Predatory fish species showed mercury levels above the recommended limit, while scalefish traditionally consumed by riverine populations were below.
Conservationists see progress for swordfish, problems for sharks at Atlantic fisheries summit
- The International Commission for the Conservation of Atlantic Tunas (ICCAT), which manages a wide range of fish stocks across the entire Atlantic Ocean and adjacent seas, held its annual meeting in Cyprus Nov. 11-18.
- The parties adopted a “harvest strategy” for North Atlantic swordfish and developed harvest strategies for a number of other species that could be adopted in coming years, drawing praise from conservationists.
- They also came to an agreement on tropical tuna management after years of wrangling; the agreement included the loosening of rules governing the use of controversial fish aggregating devices that can lead to overfishing, in a concession to European industry interests.
- Dozens of member nations supported a rule that would have effectively banned shark finning, but Japan and China blocked the effort.
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.
Overuse of antibiotics in Bangladesh aquaculture raises health concerns
- A recent study in Bangladesh reveals high rates of antibiotic resistance in pabda fish (Ompok pabda) bred by farmers through aquaculture.
- Consumption of antibiotic-resistant pabda fish may lead to the development of antibiotic resistance in humans as it exposes the food chain to multi-drug resistant (MDR) bacteria.
- Pabda aquaculture in Bangladesh produces around 20,000 metric tons annually, some of which is exported.
- Researchers are advocating educating farmers on the correct usage of antibiotics with the intervention of fisheries experts.
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 Ramsar site in Bangladesh fast loses its fish diversity amid government inaction
- Tanguar Haor, Bangladesh’s second largest Ramsar site and one of the country’s most important habitats of breeding fish, has been losing its fish diversity.
- A recent study found that the number of available fish species is now below 100 while, just two decades ago, the figure was recorded to be 141.
- Experts blame anthropogenic factors, including overfishing and habitat destruction, as the causes of declining diversity.
- However, authorities are ignoring the rising urgency for conservation and are instead celebrating the “increased fish production in the wetland.”
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.
44% of reef-building coral species at risk of extinction: IUCN
Some 44% of the world’s warm-water, reef-building coral species are facing risk of extinction, according to the latest update by the IUCN Red List of Threatened Species. This is a significant increase compared to the last assessment in 2008, when a third were considered threatened. The latest assessment covers all known coral species that build […]
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.
An ‘ocean grab’ for a property megaproject leaves Jakarta fishers grounded
- On the outskirts of Indonesia’s capital city, farming and fishing communities face displacement due to the planned construction of Pantai Indah Kapuk II, a vast complex of commercial property and mid-range apartments on the northeast coast of Jakarta’s metropolitan area.
- Farmers and fishers told Mongabay Indonesia that the developer had restricted their access to the sea, and acquired land without paying fair compensation for the value of productive trees.
- Indonesia’s fast-growing urban population has led to a housing crunch in several cities across the archipelago, with the national backlog estimated at more than 12 million homes.
- The national ombudsman’s office said no local residents had yet filed a report over land acquisition, while the developers did not respond to requests for comment.
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.
How a lineage of chiefs built a thriving fish oasis in Lake Malawi
- Lake Malawi accounts for more than 90% of landlocked Malawi’s total fish catch, and a key fishing ground is the water around Mbenje Island.
- The community here has since the 1950s practiced, and enforced, a fisheries management regime that continues to benefit both fishers and local fish stocks.
- Even as fish stocks dwindle and average fish sizes shrink elsewhere across Lake Malawi, around Mbenje Island the fish are bigger and fishers are “assured [of] a good haul.”
- The success of the management scheme is credited to the fact that it’s embedded within the community’s existing power structures, giving it “legitimacy among fishers as it has not been imposed from outside,” according to a researcher.
In Bhutan, a smoked fish tradition helps sustain a vanishing ethnic group
- Bhutan’s last remaining Olep hunter-gatherers rely on a traditional smoked fish, Nya Dosem, made from snowtrout (Schizothorax genus), to sustain their livelihoods.
- The community obtains special fishing permits to allow them to fish for these snowtrout, spending months along the Harachhu River and its tributaries in an area that is also home to the critically endangered white-bellied heron (Ardea Insignis).
- The Oleps’ fishing practices are monitored to ensure the local ecology is preserved, that spawning seasons are honored and that other local species are conserved; in this way, the environment sustains the Oleps, and the Oleps sustain the environment.
Salmon is ‘everything’ for Lummi Nation highlighted in new PBS documentary
- A new documentary, Scha’nexw Elhtal’nexw Salmon People: Preserving a Way of Life, premieres on PBS Nov. 4, following two Lummi families as they maintain fishing traditions amid declining salmon populations.
- In an interview, co-director Beth Pielert and Lummi fisher Tah Mahs Ellie Kinley discuss the film’s origins, salmon’s importance to Lummi culture, and current threats to wild salmon populations.
- For the Lummi people, salmon fishing is described as “everything” — it’s not just an activity but the foundation of their identity, with families tracing their lineage through traditional reef net sites and finding spiritual fulfillment in continuing ancestral practices.
- The filmmakers hope viewers will walk away with both understanding and hope, recognizing that while salmon face serious threats from fish farms and industrial development, there’s still time to protect these resilient fish that are essential to Lummi cultural survival.
Study maps owners of world’s high-seas ships often tied to illegal fishing
For decades, the owners of refrigerated container ships, or reefers, often associated with illegal fishing, have remained in the shadows. Now, a new study has traced 324 companies as the owners of 569 reefer vessels active between 2017 and 2022, identifying the people and countries behind these ships for the first time. Reefers are used […]
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.
Climate change and agrochemicals pose lethal combo for Amazonian fish
- A recent study evaluates the impacts on the Amazonian tambaqui fish from simultaneous exposure to a mix of pesticides and an extreme climate change scenario.
- Researchers subjected the fish to higher temperatures and higher atmospheric CO2 levels, as well as a cocktail of two pesticides, a herbicide and a fungicide, all of which are commonly used in farms throughout the Brazilian Amazon.
- The tambaqui’s capacity to metabolize the agrochemicals was found to be compromised in warmer water, and they suffered damage to their liver, nervous system and DNA.
- The study also points to the risks to food safety in the region, where fish are the main protein source: some 400 metric tons of tambaqui are eaten every year in the city of Manaus alone.
Thailand’s budding mangrove restoration plans spark both hope and concern
- Mangrove restoration projects based on mass tree planting have often proved unsuccessful due to a focus on quantity rather than carefully selecting planting sites or prioritizing long-term social and ecological gains.
- Thailand’s state-led and corporate-funded restoration approaches have typically followed this unsustainable model, prompting critics to call for more ecological and community-based approaches that place more emphasis on natural regeneration.
- Several new national initiatives aim to improve mangrove management in Thailand: A collaborative public-private program called the Thailand Mangrove Alliance aims to bring 30% of Thailand’s mangroves under effective management by 2030.
- However, a new carbon credits initiative that aims to link coastal communities with corporate partners has drawn widespread skepticism from environmental groups, who warn the scheme could effectively transform public forests into corporate lands.
Javan fisherwomen lead fight against marine dredging amid fears of damage
- Fisherwomen on the north coast of Java Island are pushing back against plans to dredge sea sand for export, saying they fear it will worsen coastal erosion and harm marine ecosystems.
- Under a 2023 regulation, the government ended a 20-year ban on sea sand exports, sparking backlash despite claims that dredging will occur only in open waters.
- Communities in the north Java districts of Demak and Jepara, where fishing is the primary livelihood, say they are particularly concerned that dredging will severely disrupt their fishing grounds and harm their livelihoods.
- Experts also warn of long-term damage both to marine ecosystems and to the economy, including losses to fishers and the undermining of Indonesia’s marine carbon storage.
Brazil dredges Amazon rivers to ease drought isolation, raising environmental concerns
- Brazil has committed to dredge major Amazon rivers in response to record drought that has lowered water levels and made ship passage, a key transportation lifeline, difficult or impossible.
- The dredging is aimed at supporting local communities, who rely on river navigation to get supplies in from outside, and producers, who need to ship their commodities out.
- But experts question whether dredging is a sustainable solution, raising concerns about long-term ecological impacts and advocating for community involvement and innovative technology for better outcomes.
- The environmental risks of dredging include ecosystem disruption, increased erosion, water contamination, and harm to aquatic species such as manatees and river dolphins.
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.
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 […]
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 […]
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 […]
Patents can serve as early-warning system for wildlife trade trends
Patent applications can reveal emerging trends in wildlife trade, a new study has found. From rhinoceros horns to pangolin scales, trade in wildlife is a highly lucrative business. In 2019, the legal global trade in wildlife was estimated to be worth about $107 billion. The illegal trade is thought to fetch between $7 billion and […]
Government inaction leaves Nepal without strategy to tackle invasive species
- A 2016 study ranks Nepal fourth globally in vulnerability to invasive species threats, particularly in agriculture.
- Yet despite drafting a management strategy to deal with the issue seven years ago, Nepal has still not finalized and implemented it.
- The country has identified 182 alien flowering plant species, with 27 considered invasive, affecting forests, agriculture and wildlife habitats.
- Experts stress the importance of swift action, noting that the window of opportunity to effectively manage invasive species is small.
Severe droughts isolate Amazon communities, study finds
The rivers of the Amazon Basin serve as highways for much of the region. Boats are often the easiest and quickest way to get goods and services in and out of remote communities and large cities alike. However, the Amazon Basin has experienced several severe droughts over the last 20 years, which have caused river […]
As southern African freshwater fish & fisheries struggle, collaboration is key (commentary)
- Freshwater fish populations in the Kavango and Zambezi (KAZA) river systems of southern Africa are in decline, so many stakeholders met last month in Namibia to share knowledge and suggest ways to address the situation.
- Of the many things shared during the conference, one message was clear: most fish stocks in KAZA are in trouble. Fewer fish means that the people and fish-dependent wildlife are also in trouble.
- “The challenges of fish conservation in KAZA are insurmountable if any of these stakeholders face them alone, but if they work together, it is possible to turn back the tide to restore fish populations and save the lives and livelihoods of our people,” a new op-ed contends.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
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 […]
Brazil’s ‘Mothers of the Mangroves’ protect an ecological and cultural heritage
- Hundreds of women from traditional communities in the Brazilian Amazon use education and local knowledge to protect the world’s largest continuous belt of preserved mangroves.
- They organize forums, seminars and workshops to teach how to harvest sustainably from the mangrove ecosystem, such as fishing for specific species within certain periods to preserve the population.
- With the support of nonprofit organizations, they also engage in financial and entrepreneurial education to boost their income and get access to fair-trade markets, contributing to stronger environmental protection and sustainable development.
- Mangroves are vital ecosystems made up of salt-tolerant trees that prevent coastal erosion, store carbon, and support thousands of wildlife species and hundreds of communities; in the Amazon, they’re threatened by expanding monocultures and proposed oil exploration.
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 […]
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.
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 […]
Hydropower plants disrupt fishers’ lives in Amazon’s most biodiverse river basin
- The Madeira Basin has the most diverse fish life in the Amazon River Basin with 1,406 species catalogued, but human interference and the climate crisis are provoking a significant decline in fish stocks.
- According to scientists, the Madeira hydropower plants have affected the hydrological cycle downstream due to irregular pulses, impacting the migratory patterns of fish.
- These disturbances have reduced the annual catch of fishers by 39% in the municipality of Humaitá.
- In the Madeira River, fishing became more costly and demanding, with fishers needing to spend more days and travel farther to spots to maintain decent productivity, which led many riverines to illegal activities.
A tribe once declared ‘extinct’ helps reintroduce salmon to the Columbia River
- For thousands of years, Kettle Falls was a vital salmon fishing ground for the Sinixt, but early 20th-century dam construction blocked salmon migration.
- Wrongfully declared extinct in Canada in 1956, the Sinixt fought for recognition and were officially acknowledged as Aboriginal Peoples of Canada in 2021.
- In 2023, the U.S. government signed a $200 million agreement with a coalition of tribes, including the Sinixt, to fund an Indigenous-led salmon reintroduction program into the Columbia River system above dams in Washington.
- Sinixt leaders say this project is an important effort to help right a historical wrong in the legacy that led to their “extinction” status, while many hope to one day join salmon efforts on their traditional territory in Canada.
Shark fin consumption wanes in Thailand, yet demand persists, report shows
- A new study in Thailand reveals consumption of shark fin has declined by more than one-third since 2017.
- Yet significant demand for shark fin and shark meat persists: more than half of surveyed citizens said they plan to consume such products in the future, despite their understanding of the ecological risks associated with killing sharks.
- Besides shark fin soup, a popular dish served at social gatherings and weddings, conservationists are increasingly concerned about emerging markets for shark parts in pet food sold in Thailand.
- Marine conservation groups say besides continued public awareness campaigns, policymakers must do more to curb shark bycatch and improve traceability of products in the shark trade to protect vulnerable species at risk of extinction.
On heavily dammed Mekong, tracking study tries to find where the fish are going
- Despite the huge environmental and economic importance of migratory fish in the Mekong River, there’s been little empirical data documenting where and how fish travel within the Lower Mekong Basin.
- For a recent study, researchers teamed up with fishers in Laos to tag hundreds of fish with transponders before releasing them to continue their migrations.
- The study found that these fish travel hundreds of miles along the river, including through several active and planned hydropower projects in Laos.
- It also found that at least a portion of the fish were able to traverse a fish ladder on an existing dam.
How Europe’s only Indigenous group is inspiring a greener Christianity
- The Sámi are Europe’s only recognized Indigenous group, having hunted, fished and herded reindeer across Arctic Europe for millennia before the arrival of Christianity.
- Today, the Sámi are fighting across their territories to resist mining, logging and energy projects that disrupt traditional activities.
- Sámi thinkers and religious leaders are pushing Scandinavia’s national churches to become allies in their fight for self-determination.
- These churches are increasingly interested in better understanding Indigenous Christian theology like that of the Sámi, which may present an alternative to a traditionally anthropocentric worldview. Some churches and followers, however, are not convinced.
Sundarbans fisherfolk are battered by cyclones amid fishing bans
- Fishers in the Bangladesh Sundarbans have been struggling with income due to damage caused to the mangroves by the recent tropical cyclone Remal and also the seasonal ban on resource hunting from June to August.
- In every disaster, poor fisherfolk are entangled more in a complex debt trap for moving on, and this year, the situation is more aggravating as the cyclone hit just before the fishing ban started.
- Nonetheless, the government is adamant on continuing the ban for the sake of forest resource conservation.
- At the same time, the government is still in the planning stage of providing people food support during the ban period, as has been provided to sea-bound fishers during the hilsa harvest ban period.
As aquaculture hits historic highs, let’s ensure sustainability is prioritized (commentary)
- The latest State of World Fisheries and Aquaculture Report indicates that for the first time ever, nations are farming more seafood than they’re catching.
- According to the FAO, world fisheries and aquaculture production has surged to an all-time high of 223.2 million tons, marking a 4.4% increase from 2020.
- “Even as world fisheries and aquaculture production hit a new high, the FAO report also documents pressing challenges that need immediate attention,” a new op-ed from the Marine Stewardship Council states.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Global migratory freshwater fish populations plummet by 81%: Report
- A new global study reveals an average 81% decline in migratory freshwater fish populations between 1970 and 2020.
- Habitat loss, degradation and overfishing are the main threats to migratory fish, which are crucial for food security, livelihoods and ecosystems worldwide.
- While 65% of species have declined, 31% have shown increases, suggesting that conservation efforts and management strategies can have positive impacts.
- The report calls for stronger monitoring efforts, protection of free-flowing rivers, and meeting global biodiversity goals to address this crisis.
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.
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.
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.
From the Amazon to the Himalayas, an invasive catfish makes its Nepal debut
- Researchers discovered specimens of Pterygoplichthys disjunctivus, an Amazonian catfish, in a river in eastern Nepal, marking the first record of this species in the country’s rivers.
- How the fish ended up here remains uncertain, with possible explanations including religious release or upstream migration from India.
- Experts warn the presence of the species could severely disrupt Nepal’s freshwater ecosystems, due to the lack of natural predators and their potential to outcompete native species.
Caught in the net: Unchecked shrimp farming transforms India’s Sundarbans
- The Sundarbans region of India has experienced a significant shift from traditional agriculture to shrimp aquaculture due to erratic weather and increasing global demand for shrimp.
- This surge in shrimp farming has disrupted local communities, displacing them from their traditional livelihoods.
- The rapid expansion of shrimp farming in the Sundarbans is often conducted without proper scientific knowledge or technical training. Scientists warn that this will have long-term consequences.
Beekeeping helps villagers tend coastal forests in Thai mangrove hotspot
- Community-led approaches to mangrove restoration are increasingly recognized as more effective than many state- or market-driven initiatives in terms of both ecological and economic outcomes.
- Nestled within southern Thailand’s mangrove-rich but fast-developing Phang Nga Bay, the village of Ban Nai Nang has developed a mangrove conservation model based on beekeeping.
- By rearing colonies of native honey bees and stingless bees that are important pollinators of local mangrove trees, the villagers earn money from honey sales, which in turn fund their community mangrove conservation efforts.
- Since they began their beekeeping and conservation activities, they’ve observed signs of rejuvenation in their local mangrove forests and are now helping neighboring villages to follow their conservation model through training and mentorship.
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.
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.
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.
Alaska’s Arctic rivers turn rusty orange as permafrost thaws
- Numerous rivers and streams in Alaska’s remote Brooks Range are turning orange due to the thawing of permafrost, which is releasing previously frozen minerals into the water.
- Water samples from the affected streams show higher acidity and higher concentrations of sulfates and trace metals, which can have significant ecological consequences, such as the disappearance of fish species and a decline in aquatic insect diversity.
- These water quality changes could severely impact Arctic fish populations, as many of the affected streams serve as crucial spawning grounds and nurseries for salmon and other fish species that are essential to the ecosystem and local subsistence fisheries.
- Researchers emphasize the need for further studies to understand the long-term implications of this issue, highlighting that the abrupt changes in water chemistry observed in the Brooks Range are a unique and concerning consequence of climate change in the Arctic.
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.
From Egypt to Syria, ‘water cancer’ chokes waterways
- Water hyacinth, an invasive species from the Amazon, is a major threat to freshwater life and livelihoods in Syria’s Orontes River and in Egypt’s Nile Delta.
- The plant grows and spreads quickly, outcompeting other species for space, oxygen, nutrients and sunlight.
- Along the Orontes, in a region controlled by opposition groups, farmers and fishers have little recourse for tackling the invasive species.
- In the Nile Delta, communities have more experience battling the plant and state-led dredging campaigns help clear water hyacinths every year, but they remain hard to control.
A tiny desert fish hits a 25 year population high in one of Earth’s harshest environments
- The critically endangered Devils Hole pupfish population has reached a 25-year high of 191 fish, offering hope for the species that lives in the smallest known habitat of any vertebrate.
- Above water and SCUBA surveys conducted by scientists twice a year carefully monitor the pupfish population in Death Valley, Nevada, which has fluctuated dangerously in the past, dropping as low as 35 individuals in 2013.
- A landmark 1976 Supreme Court decision, informed by environmental science, protected the pupfish by limiting groundwater pumping that threatened its habitat, setting a precedent for science-based conservation policy.
- Despite recent success, the pupfish remains threatened by climate change impacts on the delicate desert ecosystem, as well as growing human demand for water resources in the region.
Illegal fishing and land grabs push Cambodian coastal communities to the brink
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.
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.
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.
Tackling climate change in one of Colombia’s largest wetlands
- La Mojana, a complex network of more than 500,000 hectares (1.2 million acres) of different types of wetlands, has drastically deteriorated in recent decades.
- Thousands of farmers are working to restore their livelihoods, and the swamps, marshes and streams they inhabit.
- By doing so, they hope that floods and droughts, which are becoming more unpredictable and more severe than ever due to climate change, will affect them less.
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.
New ban threatens traditional fishers in Brazil’s Mato Grosso state
- Legislation in effect since Jan. 1 has banned fishing in Mato Grosso state rivers for five years, with heavy opposition from environmental defenders and traditional fishers.
- The bill affects part of the Brazilian Amazon Rainforest, the Cerrado savanna and part of the Pantanal wetland, one of the largest continuous wet areas on the planet.
- Experts consider fishers in the region guardians of the rivers and fear the bill could eliminate traditional fishing in the state.
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.
Fishing by dodgy fleets hurts economies, jobs in developing countries: Report
- A recent report gauged the economic damage done by fishing fleets with shady track records in five vulnerable countries: Ecuador, Ghana, Peru, the Philippines, and Senegal.
- It found that these fleets’ activities could be costing the five countries 0.26% of their combined GDP, leaving some 30,000 people jobless and pushing around 142,000 deeper into poverty.
- “The report emphasizes that the uncontrolled growth in global fishing has led to overfishing, stressing fish stocks and impacting communities and the oceans’ well-being,” one of the authors told Mongabay.
Warming seas push India’s fishers into distant, and more dangerous, waters
- Many of India’s more than 4 million fishers are sailing beyond the country’s exclusive economic zone into the high seas in search of a better catch.
- Rising sea surface temperatures, overfishing near the shore, and the destruction of reefs have decimated nearshore fisheries, forcing India’s fishers farther out to sea where they face greater risk.
- A common danger they run is straying into the waters of another country, which can lead to their boats being seized and the crew being jailed or even killed.
- The Indian government has issued policies to protect and recover nearshore fish stocks, even as it encourages fishing in the high seas.
No protection from bottom trawling for seamount chain in northern Pacific
- A recent meeting of the intergovernmental body that manages fisheries in the North Pacific Ocean failed to confer new protections for the Emperor Seamount Chain, a massive and richly biodiverse set of underwater mountains south of the Aleutian Islands.
- Bottom trawlers plied the Emperors aggressively in the past, decimating deep-sea coral communities and fish stocks.
- A proposal by the U.S. and Canadian delegations at the meeting of the North Pacific Fisheries Commission (NPFC) would have temporarily paused the limited trawling that continues there today, but failed to reach a vote.
- The NPFC did pass a separate proposal to regulate fishing of the Pacific saury (Cololabis saira), a severely depleted silvery fish that Japanese people traditionally eat in the fall.
Traditional fishers’ expertise is valuable for scientific research, study says
ARARUAMA LAGOON, Brazil — A recent study highlights the value of traditional fishers in providing reliable data on historical fishing efforts and catch sizes. Researchers involved in the study interviewed around 400 traditional fishers from various communities in Brazil and found that their recollections matched standard data collection methods 95% of the time. The findings […]
How predatory fishing has decimated Brazil coastal fish populations for decades
- A study by the ReefSYN group analyzed reef fish landings between 1950 and 2015, finding significant changes in the species caught.
- Reduced catch volumes, increased diversity of species and catches of small fish at the bottom of the food chain indicate unsustainable fishing.
- The lack of updated official data since 2015 makes fisheries management, monitoring and control more difficult in Brazil, but new measures by the Ministries of Fisheries and the Environment aim to improve this scenario.
In Java Sea, vigilantism and poverty rise as purse seine fishing continues
- Fishing communities on small islands in the Java Sea and farther afield have long complained that large purse seine vessels are encroaching on traditional fishing grounds.
- On Sembilan Island, between the islands of Java and Borneo, local fishers have resorted to vigilantism due to what they say is inaction by authorities to prevent fishing with the purse seine, known locally as cantrang.
- The head of the local fisheries department told Mongabay Indonesia that fishers would see a crackdown against the boats.
One of Colombia’s largest estuary ecosystems is drying up, communities warn
- Decades of sediment pollution, contamination and government infrastructure projects have disrupted the natural flow of saltwater and freshwater into the Ciénaga Grande of Santa Marta, one of Colombia’s key wetlands and a major estuary on the Caribbean Sea.
- Fish stocks have also plummeted, with profitable, big species being replaced by smaller ones and leaving fishing communities without their livelihoods.
- Although authorities claim that they are investing in the region, locals complain the autonomous corporation in charge is not taking steps to dredge the canals and that there isn’t enough transparency on how the money is being spent.
Island-building and overfishing wreak destruction of South China Sea reefs
- The offshore islets and reefs of the South China Sea have been the stage of intense geopolitical standoffs for decades, as the region’s coastal states compete for territorial control of the productive maritime area that includes oil and gas fields and reef and oceanic fisheries.
- A new investigation based on satellite monitoring and fisheries data reveals that overfishing, giant clam harvesting and island-building have devasted significant portions of the region’s shallow coral reefs.
- Experts say the direct loss of some of the world’s most diverse marine ecosystems is not the only cost, citing likely consequences for distant fisheries that depend on spawning grounds on some of the now-obliterated reefs.
- Actions by China and Vietnam were found to be by far the most egregious; however, experts say the onus lies on all South China Sea coastal states to work together toward solutions that will ensure the long-term protection and health of remaining reefs.
Putting a value on Indonesia’s marine resources: Interview with Annisya Rosdiana & Heidi Retnoningtyas
- A group of experts led by Annisya Rosdiana from the Fisheries Resource Center of Indonesia (FRCI) is designing Indonesia’s ocean account to determine the exact abundance of the country’s maritime and fisheries resources.
- This initiative, begun in 2021, is part of the Ministry of Marine Affairs and Fisheries’ efforts to improve sustainable marine management.
- Indonesia’s ocean account is also part of the Global Ocean Accounts Partnership (GOAP), which aims to establish globally accepted ocean accounting methods.
- The initiative faces challenges due to data deficiencies, lack of coordination among government agencies, and weak enforcement of fisheries policies on the ground.
As a megaport rises in Cameroon, a delicate coastal ecosystem ebbs
- The deepwater port at Kribi, Cameroon, is a massive project, begun in 2011 and slated for completion in 2040.
- It aims to decongest the existing port at Douala and become a trade hub for all Central African countries.
- The port is located just a few kilometers from Cameroon’s only marine protected area, home to green, olive ridley and hawksbill turtles.
- While aiming to improve the country’s economy, the port has generated unintended environmental consequences, intensifying coastal erosion, increasing human pressure and pollution, and endangering marine life and local fishers’ livelihoods.
Report shows dire state of Mekong’s fish — but damage can still be undone
- A recent report by 25 conservation organizations raises alarm about the state of fish in the Mekong River, determining that at least 19% of species are threatened with extinction.
- The report calls for the global “Emergency Recovery Plan” for freshwater biodiversity to be implemented in the Mekong, with an emphasis on letting the river and its tributaries flow more naturally, improving water quality, protecting and restoring critical habitats and species, and curbing unsustainable resource extraction.
- Despite the threats, the report notes conservation bright spots, including the discovery of new species, and emphasizes that it is not too late to protect the river, its fish, and the millions of people who depend on it.
Study identifies species with a long history but short future amid threats
- A new study analyzing human-driven extinction threats to jawed vertebrates warns that we could lose between 86 billion and 160 billion years’ worth of evolutionary history over the next 50-500 years without concerted conservation action to save unique species.
- The study is the latest in an increasing body of research that indicates evolutionarily distinctive species are frequently also those most at risk of extinction.
- Turtles and tortoises, sharks and rays, and ray-finned fish were identified as among the groups of species most at risk of extinction.
- Given that global targets under the U.N. Global Biodiversity Framework are based on safeguarding evolutionary history, the authors call on conservationists and policymakers to do more to protect such evolutionarily distinct and globally endangered species.
Lebanese youths take up rods and reels to learn sustainable fishing
- Lebanon’s fisheries face multiple challenges, including the prevalence of illegal and destructive practices, like dynamite fishing.
- New initiatives aim to shift mentalities, particularly among the younger generation.
- One of them, run by the Lebanese NGO Friends of Nature, aims to train 300 youths across the country in sustainable fishing methods.
Huge new no-fishing zones give Antarctic marine predators and their prey a break
- The government of the South Georgia and South Sandwich Islands (SGSSI), which operates as a British overseas territory, recently announced that it had established new no-fishing zones over 166,000 km² (64,100 mi²) of its existing marine protected area, and prohibited krill fishing in an additional 17,000 km² (6,600 mi²) of the MPA.
- These new no-fishing zones were established to protect krill-dependent marine wildlife, including baleen whales and penguins, while also considering the fisheries operating in the area, which target krill and other species.
- While conservationists initially pushed for further protections, they ultimately accepted the decision, with one calling it a “positive and good outcome.”
- However, Argentina, which claims the South Georgia and South Sandwich Islands as part of its Tierra del Fuego province, has expressed its dissatisfaction with the SGSSI government’s decision.
Fishers’ memories on par with scientific data on historic catches: Study
- A new study investigated how the memories of about 400 fishers from traditional communities in Brazil can serve as sources of data on historic fishing effort and catch size.
- It measured the reliability of this “harvest recall data” by comparing it to other data collected by standard scientific methods.
- The researchers found that when considered as a whole, the fishers’ memories agreed with standard data collection methods about 95% of the time, which suggests that this recall method can be an effective fisheries management tool.
Migratory Amazonian catfish placed on the international protection list
- The gilded and piramutaba catfish (Brachyplatystoma rousseauxii and B. vaillantii, respectively) were recently placed on the Convention on the Conservation of Migratory Species (CMS) list, also known as the Bonn Convention.
- These fish carry out the longest freshwater migration on the planet: The gilded or “dorado” travels 11,000 kilometers (6,800 miles) between the mouth of the Amazon River and the foot of the Andes to lay its eggs; the piramutaba swims 5,500 km (3,400 mi).
- Both species are endangered due to overfishing and construction of hydroelectric plants on rivers in the Amazon; the dorado’s distribution range has shrunk by 37% because of the dams.
Madagascar takes key step toward improving transparency of its fisheries
- Madagascar recently released its first fisheries transparency report, part of an effort to open up, democratize, and improve the sustainability of its fisheries sector.
- The report is a key step in a process defined by the Fisheries Transparency Initiative (FiTI), a Seychelles-based nonprofit.
- It contains important information on traditional, artisanal and industrial fisheries, a list of the laws and regulations governing the sector, tenure arrangements, and access agreements — including previously undisclosed information.
- It also assesses the country’s transparency according to the availability and accessibility of data from six thematic areas as outlined by the FiTI Standard.
Indonesia unveils plan to launch a satellite network for maritime monitoring
- Indonesia plans to launch a satellite constellation starting in July to monitor its marine and fisheries resources more effectively.
- This constellation of 20 nanosatellites aims to actively manage conservation efforts and ensure economic benefits from marine resources.
- The satellites will feature radio frequency, imaging and vessel-tracking equipment, allowing officials “to know every condition in Indonesia from one [data] center.”
- Challenges such as budget cuts and low compliance among fishing companies underscore the need for technological solutions to protect Indonesia’s vast marine areas.
Stalemate: WTO talks again fail to end overfishing subsidies
- At the World Trade Organization’s 13th ministerial conference (MC13), which closed in Abu Dhabi on March 2, negotiators failed to finalize phase two of an international treaty banning harmful fisheries subsidies.
- Despite 22 years of negotiations, member states remained divided on crucial aspects of the treaty to phase out subsidies worth an estimated $22 billion annually that support overfishing.
- The draft negotiating text includes contentious loopholes, raising concerns about fairness and effectiveness from state delegates, fisheries experts and scientists.
- Ratifications of phase one of the treaty leapt to 71 as 10 more states signed up during MC13, but 39 more are needed for implementation.
Should all marine reserves ban fishing? Not necessarily, new study shows
- A new study examined the performances of two types of marine protected areas: no-take MPAs, where all fishing activity is banned, and multiple-use MPAs, which allow certain forms of fishing.
- It found that no-take MPAs increased fish biomass by 58.2%, and multiple-use MPAs increased by 12.6% compared to zones without any form of protection; the study also found that both types of MPAs were more than 97% likely to improve fish populations.
- The authors suggest that multiple-use MPAs can provide “a viable and potentially equitable pathway to advance local and global conservation” when adequately designed and managed.
- However, an expert not involved in the study suggests that MPAs with full protection are more urgently needed to protect marine ecosystems like coral reefs.
Norwegian salmon farms gobble up fish that could feed millions in Africa: Report
- Norwegian salmon farms are taking huge amounts of wild fish from West Africa, mining the food security of the region, according to a report from the U.K.-based NGO Feedback.
- In 2020, the industry produced salmon feed ingredients using up to 144,000 metric tons of small pelagic fish caught along the coasts of West Africa, where they could have fed between 2.5 million and 4 million people, according to the report.
- The analysis comes as the industry faces a wave of public opposition after revelations of high mortality rates and the sale of fish deemed unfit for human consumption, along with accusations of antitrust violations by the European Commission.
Hong Kong as a reef fish haven? These scientists want to get the word out
- For the past 10 years, marine biologist and conservationist Stan Shea has been leading a citizen-science program called the 114°E Hong Kong Reef Fish Survey to compile data on local reef fish species and raise awareness about the marine environment.
- The program relies on a core network of around 50 volunteer divers, who assist Shea with his mission to raise awareness about Hong Kong’s aquatic life.
- There are likely about 500 reef fish species in Hong Kong, but only about 460 have been identified so far; Shea and his team aim to find and document as many of the other overlooked as possible.
- Shea is also working on a photographic book about Hong Kong’s reef fish, which will be published in 2026.
Landmark report on migratory species underlines threats to Asia’s wildlife
- A U.N.-backed report has found that nominally protected migratory species face the rising risk of extinction amid habitat loss and overexploitation worldwide.
- Of the 1,200 species listed in the Convention on the Conservation of Migratory Species of Wild Animals, half were found to have declining populations and one in five were threatened with extinction.
- The report found that “species occurring in Asia are the most threatened overall” and that “early indications suggest that the scale of unsustainable and illegal take may be even higher in Southeast Asia.”
New environmental rules for Chile’s protected areas rile the salmon industry
- A law that came into force in Chile last year has upset the salmon industry for imposing new requirements for salmon farms located in protected areas.
- The industry says the new rules threaten jobs and cause uncertainty in an industry that contributes 2% of Chile’s GDP.
- The salmon industry currently has 71 applications for concessions within protected areas, most of which wouldn’t meet the conditions laid out in the new rules.
- Conservation experts say the salmon industry’s reaction to this attempt at regulation is “unfortunate,” especially given its history of environmental harm.
Annual South Pacific fisheries meeting nets bottom trawling controversy
- The annual conference of the South Pacific Regional Fisheries Management Organisation (SPRFMO), an intergovernmental body, took place in Manta, Ecuador, between Jan. 29 and Feb. 2.
- SPRFMO, which manages fisheries across the vast international waters of the South Pacific Ocean, made key decisions on bottom trawling, labor rights, observation of squid-fishing vessels and transshipment at sea, a practice that can obscure the origin of illegally caught seafood.
- In what was perhaps the most controversial outcome of the meeting, delegates failed to adopt a proposal to complete the implementation of rules passed last year that would have limited bottom trawling of vulnerable marine ecosystems, such as coral communities.
Amazon catfish must be protected by the Convention on Migratory Species COP-14 (commentary)
- The latest Convention on Migratory Species of Wild Animals (also known as the Bonn Convention) meeting (COP-14) is taking place in Uzbekistan this month, and the government of Brazil has proposed protections for two catfish species with extraordinary migrations, the dorado and piramutaba (manitoa).
- The dorado’s migratory journey for instance spans a distance of 11,000+ kilometers round trip, from the Andes to the mouth of the Amazon River, and along the way it connects multiple ecosystems and feeds local and Indigenous fishing communities, but is under increasing threat.
- “During COP-14, the dorado and piramutaba will take a prominent place thanks to the Brazilian Government’s proposal to include them in CMS Appendix II…It is essential that the governments at the meeting adopt Brazil’s proposal,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
New guidebook supports U.S. tribal nations in adopting rights-of-nature laws
- A new guidebook aims to assist tribal nations across the United States in adopting legal frameworks that recognize the rights of nature.
- The growing rights-of-nature movement seeks to protect the environment by legally acknowledging its inherent right to exist and thrive independent of human use.
- The guide examines real-world challenges and pathways for passing laws and includes case studies of tribes that have enacted rights-of-nature laws through constitutions, ordinances and resolutions.
- The guide contains practical guidance on steps like surveying community perspectives, holding educational gatherings, and forming planning committees.
In East Java, social media push against Indonesia shark & ray trade lacks bite
- Over a period of four months in late 2023, Mongabay spoke with fishers and traders dealing primarily in rays and sharks in Indonesia’s East Java province.
- Advertisements for shark and ray products continued to feature on social media platforms despite pledges by companies to prevent users from conducting transactions in wildlife.
- Indonesia’s fisheries ministry said more needs to be done to enhance traceability to crack down on trade in protected shark and ray species.
Indonesia and Spain sign agreement to protect migrant fishing workers
- Indonesia and Spain have signed an agreement that will see Spanish regulators recognize competency certification issued by Indonesia for Indonesian fishing vessel workers.
- The move is part of efforts to boost protection of Indonesian migrant fishing workers in a global industry notorious for the exploitation and abuse of migrant deckhands.
- According to the fisheries ministry, some 1,000 Indonesians worked aboard Spanish fishing boats in 2021, earning on average about 1,000 euros ($1,075) per month.
- At home, Indonesia is also working to enhance training, certification, and protection for its large population of fishers and boat crews.
Critics push for more transparency at RFMOs that govern high seas fishing
- Around 17 regional fisheries management organizations (RFMOs) manage fishing in international waters, or the “high seas.”
- Scientists and civil society members have long criticized these international bodies for failing the high seas; many of the stocks they manage are overfished, research shows.
- Critics cite opaque decision-making as a key reason for conservation failures, and they’re making an increasingly vociferous case for RFMOs to become more transparent, citing their oversight of shared public resources.
- RFMO representatives, while citing internal rules as well as a need for privacy to maintain open negotiations among parties, point to recent steps toward transparency.
DNA probe uncovers threatened shark species in Thailand’s markets
- A shark DNA investigation has revealed the presence of shark species threatened with extinction in products commonly sold in Thailand’s markets.
- The study identified products derived from 15 shark species, more than a third of which have never been recorded in Thai waters, highlighting the scale of the international shark trade.
- Marine conservation groups say the findings underscore that consumers of shark fin soup and other shark products could well be complicit in the demise of threatened species that fulfill vital roles in maintaining ocean balance.
- Experts have called on Thai policymakers to improve traceability in shark trade supply chains, expand marine protected areas, and make greater investments in marine research.
Overfishing leads to decline in Bangladesh marine fish stocks & diversity
- Bangladesh is facing a decline in marine fish stocks and diversity due to lack of knowledge among fishers, proper implementation of the Marine Fisheries Act and rampant use of industrial trawlers and unauthorized fishing gear in permitted fishing zones.
- The country has a 710-kilometer (440-mile) coastline with 121,110 square kilometers (46,760 square miles) of exclusive economic zones (EEZs) within the Bay of Bengal and is a hub of 740 aquatic species.
- The marine fisheries sector contributes about 15% of Bangladesh’s total fish production, which helps meet the population’s demands for animal protein.
Indonesia invites Turkish investors to develop tuna farms in Papua
- Indonesia has invited Turkish investors to participate in offshore tuna farming in the Papua region’s Biak Numfor district, aiming to make it a hub for tuna exports.
- The Indonesian fisheries ministry said Turkish fisheries operators can bring innovation to enhance productivity and ensure sustainability of the tuna fishery.
- Indonesia, a significant contributor to global tuna production, faces sustainability challenges due to excessive harvesting of wild tuna.
- The outreach to Türkiye is the latest in efforts to get foreign investors to help develop Indonesia’s various fisheries, including a similar offer earlier in January for Vietnam to invest in lobster farms.
First ever U.S. Indigenous Marine Stewardship Area declared in California
- The Tolowa Dee-ni’ Nation, Resighini Rancheria, and Cher-Ae Heights Indian Community designated the first ever Indigenous Marine Stewardship Area (IMSA) in the U.S. along the northern California coast.
- The tribes plan to steward nearly 700 mi2 (1,800 km2) of their ancestral ocean and coastal territories from the California-Oregon border to Little River near the town of Trinidad, California.
- As sovereign nations, the tribes say they’re not seeking state or federal agencies’ permission to assert tribally led stewardship rights and responsibilities; rather, they want to establish cooperative relationships recognizing their inherent Indigenous governance authority.
- The tribes aim to restore traditional ecological knowledge and management practices that sustained the area’s natural abundance before colonial disruption.
Kenyan villagers show how to harvest more octopus by fishing less
- Residents of Munje, a fishing village south of the Kenyan port of Mombasa, have established an octopus closure to ensure sustainable fishing.
- Octopus catches in the reefs just offshore had been declining as larger numbers of fishers, often using damaging techniques, hunted this profitable species.
- Previous attempts to regulate the octopus fishery had failed, but the village’s beach management unit enlisted support from an NGO to replicate successful strategies from elsewhere.
- Clearer communication and patient consensus-building have secured buy-in from the community, and the village is anticipating a second successful harvest period in February.
Courage & calm despite attacks: Q&A with Colombian activist Yuly Velásquez
- For years, Colombia’s largest oil refinery, owned by the national oil company Ecopetrol, has discharged oil and toxic waste into water bodies, impacting fish and the livelihoods of fishers.
- Yuly Velásquez, a local fisher and president of an environmental organization, has spent years documenting water contamination and corruption linked to the refinery, and she faces consistent threats and attacks.
- According to a 2022 report by the NGO Global Witness, Colombia is the most dangerous country in the world for environmental and land defenders, with 60 murders that year.
- In this interview with Mongabay, she discusses the threats environmental defenders face in Colombia and what helps her stay resilient in the face of attacks.
How much carbon does ocean trawling put into the atmosphere?
- New research suggests that bottom trawling stirs up large amounts of carbon from the seabed and releases 55-60% of this carbon into the atmosphere within nine years.
- This amount of carbon is nearly double the annual emissions from the combustion of fuel by the entire global fishing fleet of about 4 million vessels, the study suggests.
- The authors say that the remaining 40-45% of the carbon would remain dissolved in the water, contributing to ocean acidification.
- However, this study has drawn criticism for potentially overestimating the amount of seabed carbon that trawling releases.
Indigenous effort in Bangladesh helps reverse endangered fish’s slide to extinction
- Unchecked logging and quarrying of rocks from streambeds in Bangladesh’s Chittagong Hill Tracts led to springs drying up and populations of putitor mahseer fish, an endangered species, disappearing.
- The situation was worsened by climate change impacts, characterized here by a more intense dry season during which even streams that once ran year-round now dry up.
- A project launched in 2016 and backed by USAID and the UNDP is working with Indigenous communities to reverse this decline, starting with efforts to cut down on logging and quarrying.
- As a result of these efforts, areas where forests have been conserved have seen the flow of springs stabilize and populations of putitor mahseer and other fish revive.
Global shark deaths increasing despite finning bans, study shows
- A new study finds that shark mortality increased by 4% in coastal fisheries and decreased by 7% in pelagic fisheries, between 2012 and 2019, despite legislation to ban shark finning increasing tenfold over this period.
- Based on these findings, experts say shark finning regulations may not be effective in decreasing shark mortality, and may even create new markets for shark meat.
- However, the study also shows that successful management of shark fisheries can lead to a decrease in mortality; such is the case with retention bans and other measures taken by regional fisheries management organizations.
2023’s top ocean news stories (commentary)
- Marine scientists from six international research and conservation institutions share their list of the top ocean news stories from 2023.
- Hopeful developments this past year include a monumental global treaty to protect biodiversity on the high seas and the regulation of international trade in 97 species of sharks and rays under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
- At the same time, 2023 was the hottest year on record, with widespread bleaching of corals in the Caribbean and Great Barrier Reef, and many more hot years forecast as humanity’s emissions of greenhouse gases that cause global warming continue.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Spain sanctions fishing vessels for illegally ‘going dark’ near Argentine waters
- The Spanish government sanctioned 25 of its vessels for illegally turning off their satellite tracking devices while fishing off the coast of Argentina between 2018 and 2021.
- Experts say ships that “go dark” by turning off their trackers often do so to partake in illicit behavior, such as crossing into a nation’s exclusive economic zone (EEZ) without authorization.
- While some have praised the Spanish government’s actions, one expert says he doesn’t believe the sanctions go far enough.
- Most fishing activity in this region is also unregulated and unmonitored, which raises environmental concerns.
AI and satellite data map true scale of untracked fishing and ocean industry
- A new study shows that more than 75% of industrial fishing activity and almost 30% of transport and energy activity in the oceans has not been tracked by public systems, revealing a significant gap in global observational data.
- The study, led by Global Fishing Watch, used AI to analyze 2 petabytes of satellite imagery collected between 2017 and 2021, providing unprecedented insights into hidden fishing hotspots and offshore energy infrastructure development.
- The research highlighted the potential of combining AI with Earth observation data to gain a more comprehensive understanding of ocean activities, which is needed to manage and improve the sustainability of the $2.5 trillion blue economy.
- The open-source code developed during the study can help inform policy for safeguarding ocean ecosystems, enforcing laws and identifying renewable energy expansion sites, the study authors said.
Salmon and other migratory fish play crucial role in delivering nutrients
- Pacific salmon can play a key role in transporting nutrients from marine to freshwater and terrestrial ecosystems.
- In the past, Pacific salmon and other anadromous fish that spawn in freshwater and spend part of their life in the ocean likely played a much larger role in global nutrient cycles, scientists find.
- But today, many populations of Pacific salmon and other anadromous fish are under pressure from habitat loss, overfishing, climate change, dams and other pressures that have greatly reduced their numbers, weight and ability to migrate freely.
- Population declines could further curtail their role in global nutrient transport in future, with increasing consequences, especially for nutrient-poor ecosystems that have relied in the past on migratory fish for significant nutrient additions.
Sumatran dugong hunter struggles to adapt to changing times
- The herbivorous dugong was classed as a vulnerable species in 1982 by the International Union for Conservation of Nature.
- Hunters like Munsa in Bintan, a cluster of islands between Sumatra and Singapore, have retired from hunting the mammal in response to conservation initiatives.
- However, Munsa complains that the family’s income has plummeted, and that he needs government to provide alternative livelihoods.
Study: Fishing with pesticides and dynamite puts Ecuadorian Amazon in peril
- Illegal fishing with agrochemicals and explosives across several of Ecuador’s Amazonian states is an uncontrolled problem, causing long-lasting, irreversible damage to aquatic ecosystems, recent research has shown.
- The study links high levels of poverty to the wider practice of unsustainable fishing, and calls for tighter controls on the sale and availability of agrochemicals and dynamite across the country.
- Fish caught using toxic chemicals can be dangerous for human consumption, the study warns, and says there should be more action to help educate communities about these dangers.
Fisheries observer turns up dead in latest incident in Ghana waters
- Ghanaian fisheries observer Samuel Abayateye’s decapitated body was discovered floating in a lagoon nearly six weeks after he was reported missing from the fishing vessel he was assigned to.
- Abayateye’s death follows the 2019 disappearance at sea of another fisheries observer, Emmanuel Essien, whose body has still not been found.
- Police and the Ghana Fisheries Commission say they’re investigating Abayateye’s death, but are yet to share details of an autopsy.
- The incident highlights the vulnerability of observers, who are responsible for monitoring fishing crews’ compliance with regulations, according to the Accra-based Centre for Maritime Law and Security Africa.
In 2023, Mongabay’s reporting fellows covered Earth amid crisis — and hope
- 2023 marked the first full year of Mongabay’s Conservation Reporting Fellowships, which are offered in both Spanish and English; journalists in the English-language program represented six countries in Africa, Asia and the Americas.
- The fellowships aim to fill gaps in global conservation reporting, as our planet faces the unprecedented crises of climate change, biodiversity loss and the prospects of surpassing the planetary boundaries within which human life on Earth may thrive.
- Look ahead to 2024 for much more to come, as Mongabay expands and our fellowships grow and evolve with us.
Still on the menu: Shark fin trade in U.S. persists despite ban
- An Al Jazeera investigative report has revealed that the trade in shark fins is still happening in the U.S. despite legislation banning the activity.
- The report also showed illegal shark finning operations occurring in Peru, currently the world’s largest exporter of fins due to laws that make this export legal, and in Ecuador, where sharks are landed in high volumes.
- A year ago, the international convention on wildlife trafficking enacted shark trade bans, but this has not yet stamped out the global fin trade, prompting experts to call for better enforcement and scrutiny.
Farewell, Java stingaree: Scientists declare the first marine fish extinction
- In December 2023, scientists declared the Java stingaree (Urolophus javanicus), a species of stingray, extinct.
- It’s the first marine fish confirmed to have gone extinct due to human actions.
- Scientists know very little about the species, which they haven’t spotted since a naturalist purchased the specimen from which he described the species at a fish market in Jakarta in 1862.
Causeway threatens mangroves that Philippine fishers planted as typhoon shield
- The city of Tacloban in the central Philippines was ground zero for Typhoon Haiyan, one of the most powerful tropical cyclones ever recorded and the deadliest in the Philippines’ modern record.
- A decade after the storm, the city is moving forward with controversial plans to build a road embankment and land reclamation project that proponents say will help protect the city from storm surges.
- Opponents of the plan say it threatens local fisheries, will disrupt natural storm protection measures like mangroves, and is poorly designed as a barrier against storms.
- The plan will also result in the relocation of a coastal village of 500 households, who have been active stewards of the bay’s mangrove forests.
‘Shark dust’ helps researchers ID threatened species in Indonesia fish trade
- Researchers have developed a new tool to identify a wide range of threatened and protected sharks being processed at fish factories in Indonesia.
- The method relies on DNA analysis of “shark dust,” the tiny fragments of skin and cartilage swept from the floors of fish-processing plants and export warehouses.
- From 28 shark dust samples collected from seven processing plants across Java Island, they found the genetic sequences of 61 shark and ray species.
- About 84% of these are CITES-listed species, meaning there are official restrictions in place on the international trade in these species.
The ex-shark fishermen teaching schoolkids how to protect the environment
- Shark conservationist Kathy Xu joined with ex-shark fishermen on the Indonesian island of Lombok to launch The Dorsal Effect.
- The eco-enterprise teaches students about the marine environment through snorkeling trips, coral health checks and beach trash cleanups.
- The Dorsal Effect helps provide an alternative source of income for the former shark fishermen of Lombok and aims to stop the shark finning trade.
Vast new MPAs are PNG’s first to be co-managed by Indigenous communities
- On Nov. 12, the government of Papua New Guinea declared two large new marine protected areas totaling more than 16,000 square kilometers (6,200 square miles) that reportedly triple the country’s marine area under protection.
- The announcement capped a six-year effort led by U.S.-based NGO Wildlife Conservation Society to consult with local communities about how to set up the MPAs to curtail the harvest of threatened species and restore the health of fisheries that people have depended on for generations.
- The NGO called the announcement “one of the first and most ambitious community-led MPA wins” since countries agreed last year to protect 30% of land and sea area by 2030 under the U.N. Convention on Biological Diversity.
- However, some observers note the potential problems that could arise from foreign-led conservation in an area experiencing poverty, conflict, and minimal government support, and there is widespread agreement that the MPAs’ success will depend on securing financing for enforcement.
Philippines oil spill may reverberate long after cleanup declared complete
- On March 1, the MT Princess Empress oil tanker sank in the Philippines, carrying 900,000 liters (237,754 gallons) of industrial fuel oil. A huge oil slick polluted local waters and prompted authorities to impose a ban on fishing that sent local communities into a tailspin.
- The wreck occurred in the Verde Island Passage, between the Philippines’ main islands of Luzon and Mindoro, an area with the highest concentration of marine biodiversity in the world.
- The spill cleanup activities are now finished, and life is returning to normal in many places. However, experts say the effects of the oil spill on the ecosystem could linger over the long term.
- The spill has reinvigorated calls for the Philippine Legislature to pass a law declaring the entire Verde Island Passage a marine protected area.
Amazonian expedition searches out rare ‘fish from the clouds’
- Researchers carried out a massive survey in the Brazilian Amazon for so-called annual rivulids, a family of fish whose eggs survive in a hibernation state during drought and then hatch when it rains — a phenomenon that’s earned them the name “fish from the clouds.”
- There are 200 species of annual rivulids in Brazil, nearly half of which are at risk of extinction; their fragile ecosystems — ponds, swamps and marshes — are highly vulnerable to infrastructure works like highways, ports and hydroelectric dams.
- Little studied in the Amazon, these species are subjected to stress brought on by human occupation; three new endemic species discovered during the expedition live in the Belo Monte hydropower dam’s area of influence.
- The survival of annual rivulids could be guaranteed by environmental licensing laws, but proposed legislation currently in the Senate could weaken those guidelines.
90 NGOs question Thailand Prime Minister on fisheries deregulation plan (commentary)
- Thailand’s new government is promising to “unlock” fisheries by reducing regulation and transparency around vessels’ activities.
- A letter signed by 90 NGOs questions the National Fishing Association’s proposals for fisheries reform, including returning to day-rate salaries, permitting child labor and weakening punitive measures designed to deter illegal, unregulated and unreported (IUU) fishing.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Report shines partial light on worst labor offenders in opaque fishing industry
- In recent years, examples of forced labor on industrial fishing vessels have commanded headlines in prominent media outlets. Yet ship owners are rarely held to account, often because it’s hard to identify who they are.
- A new report from the Financial Transparency Coalition (FTC), a consortium of international NGOs, examined cases of reported forced labor on 475 fishing vessels since 2010.
- The authors could only identify the legal owners (often a company) of about half the vessels, and could only identify the beneficial owners (the people who ultimately keep the profits) of about one-fifth of the vessels.
- Of the accused vessels for which it could identify legal owners, half are owned by Asian companies, and nearly one-quarter are owned by European companies.
Last of the reef netters: An Indigenous, sustainable salmon fishery
- Reef net fishing is an ancient, sustainable salmon-harvesting technique created and perfected by the Lummi and other Coast Salish Indigenous people over a millennium.
- Rather than chasing the fish, this technique uses ropes to create an artificial reef that channels fish toward a net stretched between two anchored boats. Fishers observe the water and pull in the net at the right moment, intercepting salmon as they migrate from the Pacific Ocean to the Fraser River near present-day Washington state and British Columbia.
- Colonialism, government policies, habitat destruction, and declining salmon populations have separated tribes from this tradition. Today, only 12 reef net permits exist, with just one belonging to the Lummi Nation.
- Many tribal members hope to revive reef net fishing to restore their cultural identity and a sustainable salmon harvest but face difficulties balancing economic realities with preserving what the Lummi consider a sacred heritage.
Indonesia launches new front in climate campaign focusing on seagrass
- Indonesia has published a road map for seagrass protection and rehabilitation, as part of its efforts to mitigate the impacts of the climate crisis.
- Seagrass meadows are estimated to sequester carbon dioxide from the atmosphere at a much greater rate, hectare for hectare, than even tropical rainforests.
- Indonesia has long been recognized as a crucial country for protecting the underwater flowering plants, as it’s estimated to host at least a tenth of the world’s seagrass meadows.
Fish out of water: North American drought bakes salmon
- An unprecedented drought across much of British Columbia, Canada, and Washington and Oregon, U.S., during the summer and fall months of June through October could have dire impacts on Pacific salmon populations, biologists warn.
- Low water levels in streams and rivers combined with higher water temperatures can kill juvenile salmon and make it difficult for adults to swim upriver to their spawning grounds.
- Experts say relieving other pressures on Pacific salmon and restoring habitat are the best ways to build their resiliency to drought and other impacts of climate change.
Lethal or not? Australia’s beaches are a crucible for shark control methods
- For decades, Australia’s east-coast states have attempted to keep beachgoers safe from sharks by deploying entangling shark nets and culling species deemed dangerous.
- Recent figures published by the state of New South Wales reveal that almost all the animals caught in the nets during the 2022/23 summer season were “nontarget” species, including turtles, dolphins and endangered shark species, the majority of which died due to entanglement in the nets.
- In contrast, the west-coast state of Western Australia has abandoned a shark culling regime in favor of nonlethal alternatives, such as drone monitoring and “eco barriers,” swimming enclosures that keep marine life out but do not risk entanglement.
- Despite calls from environmental groups to exclusively adopt nonlethal technologies, shark control programs are continuing in both New South Wales and its northern neighbor, Queensland, during the 2023/24 Australian summer.
Is ocean iron fertilization back from the dead as a CO₂ removal tool?
- After a hiatus of more than 10 years, a new round of research into ocean iron fertilization is set to begin, with scientists saying the controversial geoengineering approach has the potential to remove “gigatons per year” of carbon dioxide from Earth’s atmosphere.
- The idea behind ocean iron fertilization is that dumping iron into parts of the ocean where it’s scarce could spark massive blooms of phytoplankton, which, when they die, can sink to the bottom of the sea, carrying the CO₂ absorbed during photosynthesis to be sequestered in the seabed for decades to millennia.
- So far, proof that this could work as a climate-change solution has remained elusive, while questions abound over its potential ecological impacts.
- Scientists with the Woods Hole Oceanographic Institution in Massachusetts, U.S., recently received $2 million in funding from the U.S. government that will enable computer modeling research that could pave the way for eventual in-ocean testing, effectively reviving research into ocean iron fertilization.
Dominica set to open world’s first reserve centered around sperm whales
- The tiny island nation of Dominica has announced that it will create a 788-square-kilometer (304-square-mile) reserve to protect endangered sperm whales.
- Most of the sperm whales that live off the coast of Dominica are part of the Eastern Caribbean Clan, which currently has a population of fewer than 300 individuals.
- Sperm whales in this region are threatened by fishing gear entanglement, pollution, boat strikes, and even tourism.
- The new reserve aims to protect whales by restricting activities such as fishing, vessel traffic and tourism, while not entirely banning them.
The rare Amazonian fish that scientists seek to better study
Researchers recently conducted an extensive survey in the Brazilian Amazon to study annual rivulids, a family of fish known for their remarkable ability to survive droughts by entering a dormant state and hatching when it rains—earning them the nickname “fish from the clouds.” Brazil is home to around 200 species of annual rivulids, nearly half […]
Fisheries managers should act to protect swordfish this month (commentary)
- Between 1960 and 1996 swordfish declined more than 65%, the average size of fish caught shrank, and the species became severely overfished in the North Atlantic.
- A campaign led by consumer groups and chefs helped convince regulators like ICCAT to take action, to the point that the fishery is now considered ‘recovered.’
- Top chef and restaurateur Rick Moonen’s new op-ed argues that it’s time for a next step: “Now ICCAT has another opportunity to improve the long-term health of the swordfish population. This November, ICCAT members can adopt a new management approach for the stock and lock in sustainable fishing,” he says.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Nepal’s water hyacinth helps exotic fish invade, harming native species: Study
- Exotic fish species such as Nile tilapia and glassfish were introduced by humans to Pokhara, Nepal’s Lake City for various reasons, and they compete with and prey on native fish species.
- A study suggests that water hyacinth, an invasive plant species, could be helping exotic fish species in Pokhara’s lakes to invade the lakes and reduce the diversity and abundance of native fish species.
- The researchers suggest that urgent conservation action is needed to control the spread of both water hyacinth and exotic fish species, and to protect the native fish species and the ecosystem of the lakes.
To keep track of salmon migrations in real time, First Nations turn to AI
- Partnering with First Nations, a new interdisciplinary study proposes harnessing artificial intelligence and computer-based detection to count and produce real-time data about salmon numbers.
- Monitoring their population when they return to the rivers and creeks is crucial to keep tabs on the health of the population and sustainably manage the stock, but the current manual process is laborious, time-consuming and often error-prone.
- Fisheries experts say the use of real-time population data can help them make timely informed decisions about salmon management, prevent overfishing of stocks, and give a chance for the dwindling salmon to bounce back to healthy levels.
- First Nations say the automated monitoring tool also helps them assert their land rights and steward fisheries resources in their territories.
Not MPAs but OECMs: Can a new designation help conserve the ocean?
- To meet the landmark commitment struck last year to protect 30% of the ocean by 2030, the world’s nations will have to designate many new and large marine protected areas. But there’s also a different, less familiar option for meeting that target: “other effective area-based conservation measures,” or OECMs, areas that are not necessarily designed to protect biodiversity — they just happen to do so.
- Countries are now working to identify areas that meet the criteria and register them as OECMs, including in Africa where a recent webinar highlighted the promises and pitfalls of this relatively new conservation designation.
- Conservationists say OECMs could bring many positives, including the development, recognition or financing of de facto conservation areas led by local communities or Indigenous peoples.
- However, they also warn of the dangers of “bluewashing” or creating so-called paper OECMs that fail to deliver real conservation benefits in the rush to meet the 2030 deadline.
O.K. Coral: Outlaw fisher turns reef marshal in Indonesia’s Sumbawa
- Former dynamite fisher Amiruddin has ceased using destructive fishing practices and become a marine conservationist in his native Sumbawa.
- In 2010, Amiruddin was arrested and almost died while using poison to kill fish off Sumbawa’s west coast.
- Today he has installed lattices to support coral growth in the islands where he fished with explosives and poison in his youth.
Amid record melting, countries fail again to protect Antarctic waters
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with protecting marine life and managing fisheries in the Southern Ocean, met from Oct. 16-27 in Hobart, Australia, with 26 member countries and the European Union participating.
- For the seventh year in a row, the CCAMLR declined to establish new marine protected areas (MPAs) around Antarctica, despite having committed to creating “a representative network of MPAs” in 2009.
- Scientists, conservationists and some governments have been pushing for greater protections, concerned that the melting ice in Antarctica has reached alarming levels, jeopardizing some key populations of penguins, krill, whales, seals and other marine animals.
- The stalemate came even as a new threat to wildlife emerged in the region: the discovery last week that a virulent form of avian flu had reached Antarctic bird colonies.
New Caledonia expands strictly protected coverage of its swath of the Pacific
- New Caledonia, an overseas territory of France in the Pacific, recently announced that it would highly protect 10% of its economic exclusive zone (EEZ).
- These new highly protected areas will be off-limits to industrial activities such as fishing, drilling and mining.
- A decade ago, New Caledonia designated its entire EEZ as a marine protected area, the Natural Park of the Coral Sea, but industrial activities were permitted across 97.6% of that area at the time.
Can aquaculture solve the Mediterranean’s overfishing problem?
- In the Mediterranean, 73% of commercial fish stocks are fished beyond biologically sustainable limits.
- Part of the strategy to reduce overfishing promoted by the General Fisheries Commission for the Mediterranean, a regional fisheries management organization, is to promote the expansion of aquaculture, which is growing rapidly.
- However, most fish farms in the region produce carnivorous species, causing concern among experts and NGOs about the risk of worsening the burden on wild marine stocks to produce enough feed.
Report: Half of MSC-certified ‘sustainable’ tuna caught with controversial gear
- Tuna fisheries often rely on fish aggregating devices (FADs), floating human-made structures that fish congregate around, which makes it relatively easy to catch them, but which have also raised concerns about high rates of bycatch, capture of juvenile tuna, and pollution.
- Despite these concerns, the number of tuna fisheries using FADs that are certified sustainable under the standards of the Marine Stewardship Council (MSC), the largest ecolabeling scheme for wild fisheries, has soared, and FAD-fished tuna now account for more than half of all MSC-certified tuna, according to a new report from France-based nonprofit BLOOM Association.
- The report contends this constitutes a weakening of MSC standards in order to meet market demands for tuna.
- The MSC has refuted this claim, pointing to steps that certified fisheries are taking to reduce and study the impact of FADs.
As population ‘flattens,’ North Atlantic right whales remain at risk
- A new population estimate for North Atlantic right whales found about 356 individuals left in 2022, which suggests the population trend is “flattening.”
- In 2021, scientists previously estimated there were 340 right whales, although this number was later revised to 364 to account for several newborn calves.
- Despite there not being a notable difference between the population estimates in 2021 and 2022, scientists say North Atlantic right whales are still in danger of going extinct and that urgent measures need to be put into place to protect them.
South Africa’s penguins heading toward extinction; will no-fishing zones help?
- With just 10,000 breeding pairs left, the endangered African penguin (Spheniscus demersus) could be extinct in the wild by 2035 if the current rate of population decline continues.
- To protect the bird’s food supply and slow its population collapse, South Africa is throwing a protective no-fishing cordon around its main breeding colonies for a period of 10 years.
- But the devil is in the details, and conservationists say the cordons are too small to ensure the penguins get enough fish.
- Negotiations over whether to adjust the cordons are continuing in advance of an early 2024 deadline.
Fishing ban extension raises hopes for iconic Amazon pink river dolphin
- The Amazon river dolphin, or boto, is an integral feature of the rainforest’s biodiversity and culture, and is central to several Indigenous tales.
- Even though the dolphin isn’t fished for human consumption, it’s become endangered over the decades because fishers use its flesh as bait for catching piracatinga catfish.
- The Brazilian government earlier this year renewed a moratorium on fishing of piracatinga, first imposed in 2014, in the hope of saving the dolphin, but experts say fishers have just been ignoring the rule.
- The measure became even more relevant in October following the detection of more than 100 dead dolphins in an Amazon lake — experts suspect that the deaths are directly linked to the extreme drought affecting the region.
Record North Atlantic heat sees phytoplankton decline, fish shift to Arctic
- Scientists warn that record-high sea surface temperatures in the North Atlantic Ocean this year are having consequences for sea life.
- As marine heat waves there have worsened over the years, populations of phytoplankton, the base of the oceanic food chain, have declined in the Eastern North Atlantic.
- With experts predicting more heat anomalies to come, North Atlantic fish species are moving northward into the Arctic Ocean in search of cooler waters, creating competition risks with Arctic endemic species and possibly destabilizing the entire marine food web in the region.
- Lengthening and intensifying marine heat waves around the globe are becoming a major concern for scientists, who warn that the world will see even greater disruptions to ocean food chains and vital fisheries, unless fossil fuel burning is curtailed.
Conservationists condemn Nepal proposal to allow hydropower in protected areas
- The Ministry of Forest and Environment has proposed a new procedure that would allow large-scale hydropower development inside protected areas, with fewer environmental safeguards and more legal loopholes.
- Conservationists and legal experts have criticized the proposal as going against the Constitution and the National Parks and Wildlife Conservation Act as well as risking the biodiversity and ecosystem services of Nepal’s protected areas.
- They have also warned that the proposal could undermine the balance between development and conservation and expose the country to more climate change impacts such as floods and landslides.
- The Department of National Parks and Wildlife Conservation has defended the proposal as documenting the existing practices and bolstering the balance, not upsetting it.
Microplastics pose risk to ocean plankton, climate, other key Earth systems
- Trillions of microplastic particles in the ocean threaten marine life, from huge filter-feeders to tiny plankton. Although not lethal in the short term, the long-term impacts of microplastics on plankton and marine microbes could disrupt key Earth systems such as ocean carbon storage and nitrogen cycling.
- Oceans represent Earth’s largest natural carbon store and are crucial to mitigate atmospheric CO2 increase. Carbon taken up by plankton and stored in the deep ocean — known as the biological carbon pump — is a major process in ocean carbon storage. Microplastics may “clog” this pump and slow ocean carbon uptake.
- Microplastics in marine sediments alter microbial communities and disrupt nitrogen cycling, potentially magnifying human-caused problems like toxic algal blooms. Changes in plankton communities at the ocean surface could exacerbate deoxygenation driven by climate change, starving marine organisms of oxygen.
- Small plastic particles are impossible to remove from the oceans with current technology, so stopping pollution is a priority. Plastic production continues to soar year-on-year, but a U.N. treaty to address plastic pollution could offer a glimmer of hope that the international community is ready to take action.
For Indonesia’s Kei islanders, a marine protected area makes perfect sense
- Fishing communities in Indonesia’s Kei Islands support the idea of a marine protected area to safeguard their main source of livelihood from unsustainable fishing and climate change impacts.
- That’s the finding of a new study by local researchers, who found that the majority of respondents said they were also willing to contribute a token annual payment for the upkeep of such an MPA.
- The researchers have proposed the MPA to the local government and council, and say they hope that if it’s accepted, it could serve as a template for other MPAs in the region.
- The waters around the Kei Islands are blessed with some of the richest fish stocks in Indonesia, but destructive fishing practices and the impacts of climate change are threatening the age-old fishing tradition here.
Indonesian village forms coast guard to protect octopus in Mentawai Islands
- An island community in Indonesia’s Mentawai archipelago has responded to dwindling octopus stocks with a seasonal fishing closure to enable recovery.
- Global demand for octopus is expected to outpace supply over the medium term, implying higher dockside prices for many artisanal fishers, if stocks can be managed sustainably.
- Maintenance of local fishing grounds also offers crucial nutritional benefits for remote coastal communities in the Mentawais, where rates of child stunting exceed Indonesia’s national average.
On Jakarta’s vanishing shoreline, climate change seen abetting child marriages
- Marriage before the age of 18 is classified as a form of gender-based violence by the United Nations, but is commonly practiced in low-income communities to mitigate household economic pressures.
- On Jakarta’s northern coastline, child marriage is common in fishing communities responding to inflationary pressures and declining stocks of fish in near-shore waters.
- Janah, now 23, fears she lacks the agency to break a cycle that saw her married at the age of 16.
Seventy-plus nations sign historic high seas treaty, paving way for ratification
- As of Sept. 22, 76 nations and the European Union had signed the high seas treaty while gathered at the 78th U.N. General Assembly in New York.
- After signing the treaty, each nation must ratify it. Then, once 60 nations have ratified the treaty, it will come into force after 120 days.
- The high seas encompass two-thirds of the world’s oceans, but only 1% currently has protected status.
‘Totally unsustainable’ sand mining harms marine environments, new data suggest
- New data from the newly launched platform Marine Sand Watch suggest that the dredging industry is extracting about 6 billion tons of sand from the marine environment annually.
- Experts say the extraction of sand can have numerous impacts on the marine environment, such as harming biodiversity, polluting water and making coastlines more vulnerable to sea level rise.
- While the sand mining industry is currently operating at unsustainable levels, experts say there are solutions to mitigate its damage.
Study finds old pear trees make for surprisingly rich reef habitats
- In a new study, researchers used old pear trees to create artificial reefs and settled them in the Wadden Sea in the Netherlands to see what kinds of marine biodiversity aggregated on or around them.
- They found that the tree reefs attracted a surprising amount of biodiversity over a short period of time, including sessile organisms like barnacles and mobile species like fish and crabs.
- The authors say tree reefs can be replicated in other parts of the world, mainly temperate regions.
Court order fails to stop poison fishing in Bangladesh Sundarbans
- According to the Bangladesh Forest Department, the Sundarbans mangrove forest in Bangladesh shelters about 210 species of white fish, 24 species of shrimp, 14 species of crabs, 43 species of mollusks and one species of lobster.
- About 1.7 million locals living adjacent to the mangrove forest directly or indirectly depend on forest resources, including fish and crabs, for their livelihood due to the region’s growing unemployment rate.
- Among them, some fishers have been using poison to catch fish, even during the banned period, which eventually damages forest ecology and the health of those who consume the fish caught with poison.
- Considering these damages to the world’s single largest mangrove forest as well as to human health, the Bangladesh High Court issued a verdict responding to a writ petition to stop the heinous practice in September 2021, though the practice is still ongoing.
For South Africa’s small fishers, co-ops prove a necessary, but bumpy, step up
- Sixteen years after small-scale fishers in South Africa were promised legal recognition and fishing rights, the policy regulating the new sector is at last being implemented.
- As fishing communities draw closer to finally claiming equal rights in a fishing industry that has been dominated by the commercial sector, they are currently forming cooperatives to access collective fishing rights and co-manage local marine resources.
- The rollout of the new policy has been long and bumpy, with many issues still to be resolved, and long-time fishers complaining they’ve been excluded.
- Even so, hope remains that cooperatives can hold new opportunities for income generation and equity building.
Expected ship traffic to LNG Canada port could see whale deaths also rise
- The nutrient-rich ancestral waters of the Gitga’at First Nation in northern British Columbia are a critical habitat for fin, humpback and killer whales.
- The development of a $35.5 billion LNG terminal threatens these whales, as shipping traffic in the region is projected to surge, leading to more frequent encounters between whales and ships, a recent study warns.
- It uses whale movement data and predicted ship traffic modeling to conclude that two fin whales and 18 humpback whales could be killed each year in ship strikes in Gitga’at territorial waters.
- Researchers suggest mitigation measures like reducing ship speeds in whale hotspots and restricting ship traffic during August, when whales are most abundant in these waters.
Offshore drilling faces backlash in Argentina after skirting environmental regulations
- Argentina granted permits to a dozen major oil companies to develop new offshore drilling projects near the Atlantic coast. But some of them may have disregarded policies meant to protect surrounding marine ecosystems.
- A court filing by the Environment and Natural Resources Foundation (FARN) argues that offshore drilling exploration could disorient, injure and even kill marine life and disrupt feeding and migratory areas.
- The companies that received permits include Equinor, Exxon Mobil, Qatar Petroleum Pluspetrol, Shell, Tullow, Total Austral and Shell, among others.
As Bangladesh’s crab fishery booms, its wild stocks suffer the fallout
- Crab harvests in Bangladesh are booming to meet thriving export demand, but the rates at which wild stocks are being depleted may be unsustainable, experts warm.
- Researchers say the loss of large numbers of mud crabs from ecosystems like the Sundarbans mangroves could trigger an ecological imbalance.
- Bangladesh exported about $35 million worth of crabs in the 2019-2020 fiscal year, with the trend expected to increase to markets like the U.S., the EU and Singapore.
- Experts have called for more efforts to hatch crabs on aquafarms as a way to ease the pressure on wild stocks, but this option isn’t available yet at commercial scale.
Indonesian illegal shark and ray exports remain rampant amid poor monitoring
- Indonesia allows the trade of some endangered shark and ray species, but illegal exports remain rampant and unchecked.
- Mongabay-Indonesia conducted an investigation earlier this year to learn about the regulations, the loopholes and the challenges within the complex trade and fisheries of sharks and rays.
- The investigation found that the lack of oversight in the field was the leading cause of illegal shark and ray trade in the country.
- Indonesia is home to more than a quarter of the world’s 400 known shark species; a fifth of all shark species are endangered.
Madagascar signs new ‘sustainable’ tuna deal with the EU
- In late June, Madagascar and the European Union struck a new four-year deal allowing fishing vessels flagged to EU countries to resume harvesting tuna in Madagascar’s waters after an unusual four-and-a-half-year gap.
- The EU says the deal benefits Madagascar by providing key funding to support fisheries governance, and civil society groups praised the Madagascar government for creating a more inclusive and transparent negotiating process than in the past.
- However, critics contend that the deal offers little benefit to the citizens of Madagascar, one of the poorest countries in the world, and enables European vessels to exacerbate the overfishing of Indian Ocean tuna stocks.
Study: Protecting marine life is a big benefit to local communities, too
- A new study of the Mesoamerican Reef in the Caribbean found that marine protected areas (MPAs) are not only beneficial for conservation but can also lift up the socioeconomic status of the local and Indigenous communities that live near them.
- Led by the Smithsonian Environmental Research Center, the study used data from the Healthy Reef Initiative and USAID to analyze social and economic factors like income, food security and the rates of stunted growth connected to chronic malnutrition in children.
- One reason that MPAs benefit local and Indigenous communities is that no-take zones reach their carrying capacity as fish populations grow and recover, creating “spillover” into waters without fishing restrictions.
‘The deep sea is vital to protect the ocean’: Q&A with France’s Hervé Berville
- In November, France took a strong position on deep-sea mining by declaring that this future activity should be banned in international waters. The nation has also banned it from its national waters.
- Berville also said he wants to make sure there is a “coalition in favor of a principle of precaution or moratorium.”
- Member states of the International Seabed Authority, the UN-associated mining regulator, recently agreed to push back its timeline for finalizing rules that would enable deep-sea mining to start.
- Mongabay’s Elizabeth Claire Alberts interviewed Berville at the French Embassy in Kingston, Jamaica, during the meeting of the ISA assembly in July.
Plastic ‘Frankenrocks’ pose new pollution threat to coastal environment
- Scientists are finding more evidence of a new, insidious form of plastic pollution: melted plastic that has melded with rocks, coral and other naturally occurring material in coastal areas.
- Samples of these “Frankenrocks” collected from a single beach on a single island in Indonesia were likely formed by the burning of plastic trash.
- They pose a danger to marine life because they can break down into microplastics that then enter the food chain, and can also leach toxic chemicals into the environment.
- Scientists have called for more study into this new and growing phenomenon, saying these Frankenrocks require specialized cleanup management to ward off a “serious problem.”
The endless struggle to clean up Rio de Janeiro’s highly polluted Guanabara Bay
- Once a nursery for marine life, Guanabara Bay in Rio de Janeiro is now dying from the dumping of thousands of liters of sewage into its waters; artisanal fishers now survive by picking up the garbage that floats in the bay.
- Faced with failed promises of de-pollution by the government, civil society organized itself, creating areas of environmental protection and pressuring the companies responsible for basic sanitation in the state, which is still deficient today.
- On the shores of the Rodrigo de Freitas lagoon, a biologist started replanting the mangroves; life returned and the site has become a model of what can be done to save the Guanabara Bay.
‘Mud, muck and death’: Cambodia’s plan to obstruct trawlers and revive local fishing
- On Cambodia’s coast, a local NGO is building concrete underwater structures in an effort to deter destructive illegal trawlers that kill most everything in the habitat.
- The structures also serve as artificial reefs that provide small nurseries for fish, sponges, grasses and other species.
- An ambitious government plan will erect the structures near 25 fishing communities along the country’s coastline in a bid to revive Cambodia’s nearshore marine fisheries, besieged by years of destructive illegal fishing and increasing development.
- If successful, the plan could bring an influx of funding to fishing communities hit hard by the destruction of marine habitats and loss of income that have forced many to leave in search of other work.
Offshore oil plans in Brazil threaten South America’s largest coral reef
- The Parcel de Manuel Luís coral reef, off the coast of northeastern Brazil, is a vital habitat for several species, including 53 at risk of extinction.
- Despite vetoes from Brazil’s environmental regulator, the local government is seeking to give the go-ahead to oil drilling projects in this part of the Pará-Maranhão Basin.
- Oil drilling in the region also poses a threat to the longest continuous stretch of mangrove in the world, which runs from the Maranhão coastline to the northern state of Amapá, in the Amazon.
Scientists: Fishing boats compete with whales and penguins for Antarctic krill
- Scientists and campaigners recently documented huge krill fishing vessels plowing through pods of whales feeding in Antarctic waters, a permitted practice they say deprives the whales of food.
- As Antarctic waters warm due to climate change, krill numbers are declining, stressing wildlife that rely on the small crustaceans at the bottom of the food chain.
- The intergovernmental body in charge of regulating the krill fishery, the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), has taken specific steps to protect penguins and seals but not whales.
- At the same time, CCAMLR has stalled on the establishment of new marine protected areas and the adoption of new conservation measures. A special meeting to advance protected areas concluded June 23 with no progress.
Clean me a river: Southeast Asia chokes on Mekong plastic pollution
- New research shows that the drift of microplastics from the Mekong River to the coastlines of countries around the South China Sea depends on variable factors, including seasonal changes in winds and ocean currents.
- The Philippines is most exposed to plastic waste that mainly drifts from the Mekong River to the sea during the monsoon season, with 47% of the stranded particles ending up on its coast, followed by Indonesia at 24%, Vietnam at 17%, and Malaysia at 8%.
- Environmental advocates say the findings of this study underscore the importance of international cooperation in combating plastic pollution, which harms marine biodiversity and coastal economies.
West African fishers strike for fair wages and ‘respect’ on EU-owned vessels
- African fishers, mostly from Senegal and Ivory Coast who work on dozens of EU vessels that operate in West Africa and the Indian Ocean, took part in a strike that lasted from June 5-8, alleging wage violations.
- Vessels owned by EU companies are allowed to fish in foreign countries’ waters through agreements between the EU and the host nations. However, a third of such vessels operating in West Africa use flags of other countries and evade labor rights provisions agreed to under these pacts.
- Fishers who participated in the strike told Mongabay they were fighting for more than fair wages, saying that African sailors were not treated with respect on European boats despite doing some of the most arduous jobs.
- Seafarers’ unions called off the strike after the Senegalese government initiated negotiations with vessel owners and unions. Talks are expected to conclude in five months.
Popular aquarium fish from Thailand and Myanmar is new-to-science species
- Redtail garras, known for their bright orange tails and elongated snouts, are popular aquarium fish, but information about their biology has been scarce until recently — when they were described as a new species.
- Redtail garras primarily eat algae and arthropods by scraping them off rocks using specialized mouthparts. They have unique features like a snout covered in tubercles, which are hardened scales used as weapons.
- The species was named in honor of Nonn Panitvong, a Thai businessman and naturalist recognized for his efforts in biodiversity conservation.
- The late recognition of the redtail garra emphasizes the need to better understand biodiversity in understudied areas, and reflects the underestimate of fish diversity in Southeast Asia.
How to ‘flip’ a paper park: Success in the North Sea carries lessons
- A recent study found that 27% of surveyed marine protected areas (MPAs) were likely “paper parks” that fail to confer real ecological protection.
- There are different kinds of paper parks, including those with overly permissive rules and those where the rules are not followed or enforced.
- Discussions among conservationists have turned to how to “flip” paper parks to make them more effective. This can require changing park rules, often only through sustained pressure on governments, or improvements in MPA management, which can be costly.
- It’s a crucial time for figuring out how to make MPAs more effective; in December, nearly 200 countries signed a landmark agreement to conserve 30% of Earth’s land and sea by 2030, committing to more than triple MPA coverage within seven years.
Opposition grows to Indonesia’s resumption of sea sand exports
- Marine conservation and fisheries activists in Indonesia are pushing for exports of sea sand to be scrapped, saying the activity harms the environment and community livelihoods.
- Indonesia imposed a ban on exports of dredged sea sand in 2003, but reversed the policy through a regulation issued in May this year.
- Activists say the policy directly threatens the future of Indonesian fishing and coastal communities in the world’s largest archipelagic nation, where millions of people are dependent on fishing for their livelihoods.
- Others say the resumption of exports will benefit foreign interests, including Singapore, which has expanded its land area by 20% thanks largely to Indonesian sand, and China, which is building artificial islands to shore up its claims to parts of the South China Sea.
