How cockfighting imperils Peru’s critically endangered sawfish
- Mongabay’s new film “Why cockfighting is threatening Peru’s last sawfish” investigates how the critically endangered largetooth sawfish has become a victim of Peru’s legal cockfighting industry.
- Although the species has nearly disappeared from Peru’s Pacific waters, its rostral “teeth” continue to circulate in informal markets, prized for use as cockfighting spurs.
- A single sawfish can yield dozens of spurs, each worth up to $250, creating powerful economic incentives for artisanal fishers facing financial hardship.
- Through interviews with fishers, scientists and cockfighting industry leaders, the film explores whether cultural change within the sport can outpace the illegal trade before the species disappears entirely.
Sustainable fisheries can’t be built on exploited labor (commentary)
- The connection between human welfare and ocean conservation is direct and unavoidable, a new op-ed argues, because lawlessness toward people often goes hand in hand with lawlessness toward the ocean.
- Although there is an international legal framework governing crew welfare on fishing vessels at sea, these protections remain uneven, weakly enforced, or entirely absent for too many fishing crews, particularly migrant workers deployed on distant-water fleets.
- “We cannot reasonably expect crews to comply with complex fisheries regulations including logbooks, bycatch mitigation, finning bans, spatial closures and other requirements when they are overworked, underpaid, isolated and afraid,” the author writes.

Trump opens only US marine national monument in Atlantic to fishing — again
- U.S. President Donald Trump issued a proclamation on Feb. 6 to open the Northeast Canyons and Seamounts Marine National Monument, a marine protected area off the northeastern U.S., to commercial fishing.
- Trump wrote that reopening the area will not endanger marine species and will help the fishing business, and industry groups praised the proclamation.
- Conservationists decried the move, saying the monument is a critical sanctuary for marine life and the food webs that serve the interest of the U.S. public.
- The Trump administration has also moved to deregulate the other U.S. marine national monuments, which are in the Pacific Ocean.
Critical shark and ray habitats in Western Indian Ocean largely unprotected: Study
- Almost half of the Western Indian Ocean’s shark and ray populations are considered threatened with extinction, as populations decline.
- The Important Shark and Ray Areas (ISRAs) project has mapped out 125 areas across the Western Indian Ocean that are critical for the survival of many species.
- Yet only 7.1% of these ISRAs fall within existing marine protected areas, and just 1.2% are in fully protected areas where fishing is prohibited.
- Researchers identified challenges related to fishing pressure as the most significant threat to sharks and rays in the region.
Cowboy boots made from pirarucu leather fund Amazon’s sustainable fishery
- Sustainable pirarucu fisheries in Brazil’s Amazonas are restoring once-depleted populations of this freshwater giant, thanks to community-led management systems and sales to brands overseas.
- Selling pirarucu skin to the fashion industry, especially for Texas-bound cowboy boots, is key to financing the fishery, helping maintain fair prices for fishers and cover part of the high costs of transport, storage and community monitoring.
- The system depends on heavy collective labor and constant protection against illegal fishing, with communities traveling long distances, patrolling lakes and facing armed threats — all while receiving limited recognition or policy support from authorities.
Fishing ‘modernization’ leaves Tanzania’s small-scale crews struggling to stay afloat
- Tanzania’s boat modernization program aims to empower small-scale fishers with affordable, government-distributed vessels, but has instead left many struggling with unreliable vessels and unsustainable loans.
- In Kilwa district, fishers say the boats they received were poorly equipped, costly to operate and prone to mechanical failure, forcing them to rent missing gear and spend more on fuel.
- Mounting repayment pressure is driving some fishers toward illegal or risky fishing practices, undermining the project’s goal of promoting sustainability.
- Experts warn that poor consultation, mismatched designs and a lack of community input threaten to turn Tanzania’s fisheries modernization plan into a long-term burden rather than a solution.
Pacific fisheries summit gives a boost to albacore & seabirds
- The Western and Central Pacific Fisheries Commission (WCPFC), a multilateral body that sets fishing rules for an area that covers nearly 20% of the planet, held its annual meeting Dec. 1-5 in Manila, the Philippines.
- The parties adopted a harvest strategy for South Pacific albacore (Thunnus alalunga) that will set near-automatic catch limits based on scientific advice, considered a best practice in fisheries management. Conservationists celebrated the move.
- The parties also adopted a measure that aims to keep seabirds from drowning on industrial fishing lines.
- They didn’t adopt any new rules on the ship-to-ship transfer of fish and other goods at sea, a practice known as transshipment that’s been linked to illegal fishing and other illicit activity.
Artisanal fishers in Liberia question benefits of new tracking devices from government
- The Liberian government earlier this year distributed 400 automatic identification system (AIS) transponders to small-scale fishers in the counties of Grand Cape Mount, Grand Bassa, Margibi and Montserrado.
- The devices transmit a vessel’s position and speed via radio signals, and Liberian authorities say they hope it will help in speeding up responses to vessels that are in distress.
- However, many small-scale fishers appear reluctant to adopt the new device, with some saying they would prefer GPS-equipped devices that let them track their own location.
- The Liberia Artisanal Fishermen Association (LAFA), an advocacy group, blames the low adoption rate on the inadequate involvement of fishers during the design and rollout of the project.
Study finds more ‘laggards’ than ‘leaders’ among high seas fisheries managers
- A new paper suggests that regional fisheries management organizations (RFMOs) haven’t done a very good job setting up systems to conserve fish stocks and broader ecosystems.
- The paper questions RFMOs’ readiness for a coming new era of marine governance, with the high seas treaty set to take effect in January.
- The authors rated 16 RFMOs based on 100 management-related questions, such as “Are there consequences for violations of conservation measures …?” and used the answers to help identify “leaders” and “laggards.” The average rating was 45.5 out of 100.
- They also determined that on average, more than half of RFMOs’ target stocks are overexploited or collapsed, reinforcing previous research.
With a target on their bellies, can California’s sturgeon survive?
- California’s green sturgeon and white sturgeon face numerous threats from dams, harmful algal blooms and overfishing.
- White sturgeon are highly prized for their eggs, which are made into caviar.
- Their numbers have dropped so precipitously that they’re now being considered for protection under the California Endangered Species Act.
- The state banned commercial sturgeon fishing in 1954, but the amount of poaching and caviar trafficking is unknown, and there have been cases linked to criminal networks involved in other illegal activities.
‘Myopic’ fisheries managers toy with a new ‘tragedy of the commons’ (commentary)
- There are many examples of “tragedies of the commons,” whether in the atmosphere as a result of carbon dioxide pollution, or in the oceans because of marine plastics. But arguably the largest in the world is caused by overfishing, a new op-ed argues.
- The general absence of effective fisheries regulations that ensure the conservation of healthy fish populations endangers whole oceans and the billions of people who depend upon fish for their livelihoods.
- “Currently, fisheries ministers are myopically obsessed with the pain the industry always claims it would suffer next year if the right conservation policies were adopted. They should look instead at how long we have been getting it wrong, and how quickly things could be turned round,” a new op-ed argues.

45 more shark species up for CITES protections; tight vote expected
- Twenty-nine houndsharks and 16 gulper sharks are up for listing on CITES Appendix II at the wildlife trade regulator’s summit in Uzbekistan this week.
- Conservationists expect the vote to be close, with critics saying “lookalike” species shouldn’t face trade restrictions. Proponents argue it’s necessary given the lack of knowledge among customs officials.
- Houndsharks are widely consumed for their meat in Europe and Australia, while gulpers are hunted for their liver oil.
The roughed-up roughy fish (cartoon)
The orange roughy may be among the oldest living deep-sea fish in the world, with a lifespan of up to 250 years. But bottom trawling practices in Australia and New Zealand might have already decimated their slow-breeding populations beyond recovery.
For sharks on the brink of extinction, CITES Appendix II isn’t protective enough (commentary)
- Listing shark species under CITES Appendix II, which allows for well-monitored sustainable trade, has helped to save some sharks from extinction. But some species are so threatened that they need to be listed on Appendix I, which bans all trade.
- New research has revealed that many fins belonging to sharks protected by Appendix II are still being sold in large numbers in Hong Kong, one of the biggest markets, supporting the need for action on Appendix I listings for some species at the CITES COP20 meeting that commences next week in the Uzbek city of Samarkand.
- “Governments meeting at COP20 in Uzbekistan should follow the science, support these proposals, and help save these sharks and rays from the brink of extinction. It’s the only way to give these species a fighting chance at survival,” a new op-ed argues.

West Africa’s oceans get $68 million lifeline amid fisheries decline
A coalition of international organizations has launched the West Africa Sustainable Ocean Programme to tackle the region’s deepening fisheries decline. Led by the IUCN (the global wildlife conservation authority), Expertise France and the Fisheries Committee for the West Central Gulf of Guinea (FCWC), the WASOP initiative aims to curb illegal fishing, restore marine ecosystems, and […]
Embrace ‘blue’ foods as a climate strategy at COP30, fisheries ministers say (commentary)
- The “blue” or aquatic foods sector is often overlooked as a climate strategy, despite its potential to help meet demand for protein with a smaller environmental footprint, fisheries ministers from Brazil and Portugal argue in a new op-ed at Mongabay.
- Many blue foods generate minimal carbon emissions and use modest amounts of feed, land and freshwater, and their increased consumption could cut annual global CO₂ emissions by a gigaton or more.
- “Brazil and Portugal stand ready to champion global efforts to harness and safeguard blue foods for climate mitigation and adaptation strategies, generating multiple benefits across sustainable development goals. We call on more countries to implement measures across the blue food sector that strengthen food security and climate strategies at COP30 and beyond,” the authors write.

Antarctic conservation summit closes with stalemate on MPAs & krill fishing rules
- The annual meeting of the international body responsible for the conservation of Southern Ocean marine ecosystems concluded Friday with no progress on two contentious issues before it: the creation of new marine protected areas and the strengthening of regulations governing the fishery for krill (Euphausia superba), a species on which numerous iconic species of Antarctic wildlife depend.
- This year’s annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) was particularly tense, due to a clash between two occasionally overlapping groups of countries: on one side, those working to establish new marine protected areas (MPAs), and on the other, those more focused on increasing krill fishing.
- CCAMLR has considered proposals to establish three large MPAs annually for years but has failed to pass them under its consensus-based decision-making process. This year was the same, due to vetoes of MPA proposals by Russia and China.
- The combination of a lack of will to reinstate previously agreed regulations governing the krill fishery and a new push to drastically increase the krill harvest suggests a change in direction at CCAMLR toward more permissive fishing.
Chaos on Cambodia’s Coast
Along Cambodia’s rapidly transforming coastline, illegal trawling, elite-backed development, and weak enforcement are driving marine ecosystems and fishing communities to the brink. This 2024 series investigates the institutional breakdown behind the country’s marine crisis, from ineffective patrols in protected areas to billion-dollar land deals displacing small-scale fishers. It examines the competing interests reshaping Cambodia’s coast, […]
Norway’s proposal to double krill harvests raises tension at Antarctic conservation summit
- Norway has proposed almost doubling the catch limit for krill in the Southern Ocean, a proposal that has exacerbated tensions at the annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) in Australia. Conservationists have expressed concern because the continent’s iconic wildlife depend on krill for sustenance.
- The CEO of Aker BioMarine, a Norwegian company that dominates the Southern Ocean krill catch, said it has been working with CCAMLR member countries to advance the proposal as well as create a marine protected area around the Antarctic Peninsula.
- Chinese and Russian delegates have voted for years to veto new marine protected areas in the Southern Ocean.
- Russia came into the spotlight at this year’s meeting following its arrest of Leonid Pshenychnov, a researcher at the Ukrainian Institute of Fisheries, Marine Ecology and Oceanography and a longtime member of the Ukrainian delegation to CCAMLR.
Report finds dangerous mercury levels, highlights mislabeling in shark meat sold in EU
- Nearly a third of shark meat samples taken from products sold in Europe contained dangerously high methylmercury levels, with all tope shark and almost a quarter of blue shark samples exceeding EU safety limits, a new study finds.
- Much shark meat is mislabeled under names like rock salmon, huss or veau de mer, leaving consumers unaware they’re eating shark and could be ingesting a potent neurotoxin.
- Methylmercury can’t be cooked out, builds up in human tissue and can cause lasting neurological harm. Meanwhile, shark populations are declining, threatening marine ecosystem stability.
- The study’s authors urge stricter labeling laws, tighter food monitoring and consumer education, arguing that eating apex predators is both ecologically and medically unsustainable.
Two years later, no closure for family of missing Ghanaian fisheries observer
- Samuel Abayateye, a father of two, tasked with monitoring a Ghana-flagged tuna-fishing vessel, was reported missing on Oct. 30, 2023.
- Two years on, his family still hasn’t receive any formal updates from the Ghanaian police or any other agency about what happened to Abayateye.
- The authorities haven’t shared the results of a DNA test on a body found a few weeks after Abayateye went missing, which the family believe was his.
- Mongabay made repeated attempts to contact the police, but didn’t receive a response about the case.
Global conservation body takes first step to protect ocean’s twilight zone
- Delegates at the IUCN World Conservation Congress in Abu Dhabi voted to adopt a motion urging precautionary measures to protect the ocean’s mesopelagic zone.
- The nonbinding motion calls for prospective activities such as fishing in the mesopelagic zone, deep-sea mining and geoengineering to be guided by the best available science and approached with caution.
- Both conservationists and industry representatives expressed support for the motion, highlighting the mesopelagic zone’s ecological importance and potential as a sustainable resource.
South African sharks threatened by fisheries, weak enforcement
- The only permit holder in South Africa’s demersal shark longline fishery has been reported breaching permit regulations, raising questions about the sustainability of the fishery.
- The fishery targets critically endangered and endangered shark species with no catch limits in place to prevent overfishing.
- Target species are already depleted, according to scientific assessments, while little is known about bycatch of other protected and endangered species.
Indonesia falls short in bid to increase its share of southern bluefin tuna catch
- The Commission for the Conservation of Southern Bluefin Tuna (CCSBT), a multilateral body that manages the stock of southern bluefin tuna, held its annual meeting Oct. 6-9 in Bali, Indonesia.
- Indonesia pushed for a larger share of the global catch, which is currently dominated by Australia and Japan, but CCSBT members instead kept each nation’s share unchanged.
- Members also agreed to once again fully fund a key stock monitoring program, and to set up a future meeting for discussion of seabird protection in the fishery, amid criticism from conservationists that the commission hasn’t done enough to protect seabirds.
Abandoning Antarctic krill management measure threatens conservation progress (commentary)
- Until 2024, spatial limits across four sub-areas of the Antarctic Peninsula region had reduced the risk of concentrated fishing in areas preferred by whales, seals and penguins.
- The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) had taken an ecosystem-based approach, recognizing that effects of fishing can ripple through ecosystems; but with the recent lapse of its Conservation Measure 51-07, ships can now concentrate their fishing efforts in key wildlife foraging hotspots.
- This October, as delegates gather to discuss CCAMLR priorities, the authors of a new commentary argue that, “At stake is more than a fishing rule, but also the commitment to manage fisheries proactively, rather than reactively.”
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.
Global treaty to end subsidies for destructive fishing takes effect
A landmark global treaty to curb billions of dollars in government subsidies for overfishing took effect on Sept. 15, Mongabay contributor Elizabeth Fitt reported. The agreement marks the first time the World Trade Organization (WTO) has approved an environmental sustainability agreement in its 30-year history. The deal came into effect after Brazil, Kenya, Tonga and […]
UK rejects total ban on bottom trawling in offshore marine protected areas
The U.K. government has rejected calls to fully ban bottom trawling in its offshore marine protected areas, despite evidence that the fishing practice tears up seabed habitats and releases large amounts of carbon. Bottom trawling involves dragging weighted nets across the seafloor, often crushing coral reefs and sponges while stirring up sediments. The huge nets […]
Illegal fishing threatens unique marine ecosystem in Peru
- Park rangers who patrol Illescas National Reserve often confront fishers who use chinchorros, a type of fishing net that is banned in Peru.
- The reserve is designated solely as a terrestrial protected area, which often limits the park rangers’ ability to act, as the marine area is outside their jurisdiction.
- Conservationists warn of the urgent need to safeguard this important marine area and its rich biodiversity.
‘Super big deal’: High seas treaty reaches enough ratifications to become law
- The agreement on marine biodiversity of areas beyond national jurisdiction, also known as the high seas treaty, was reached in 2023 with much fanfare in marine conservation circles, partly because it sets up a system for establishing marine protected areas (MPAs) in international waters.
- On Sept. 19, Morocco became the 60th country to ratify the deal, which means it will become binding international law in January 2026.
- Experts and advocates celebrated the milestone, calling it a win for conservation and international cooperation.
- Uncertainty remains in how the treaty will interact with other regulatory regimes for fishing and mining, among other activities.
Pet sharks have become cool, but is owning them ethical?
- Owning a shark and keeping it in a home aquarium has become cool — and it’s no longer just the province of tech bros and celebrities.
- But experts note that most home aquariums are inadequate and can lead to stunted growth, deformities and early death.
- Yet sharks are often easy to buy, with some selling for as little as $90 online; zebra sharks (Stegostoma tigrinum), which are endangered, go for around $6,000.
24 years on, part one of WTO treaty curbing fisheries subsidies takes effect
- The first part of the WTO’s treaty banning harmful fisheries subsidies, known as Fish One, entered into force Sept. 15 after more than two decades of negotiation and three years of ratification.
- It bans subsidies for IUU fishing and exploitation of overfished stocks while requiring parties to the treaty to disclose detailed data on fleets, catches and subsidy programs.
- Yet it allows certain subsidies to persist; for instance, for fishers targeting unassessed fish stocks or “managed” overfished stocks.
- The treaty will lapse in four years if no follow-up “Fish Two” deal can be reached, but negotiations remain stalled.
Countries shorten tuna fishing closure at Pacific summit with few conservation ‘wins’
- The Inter-American Tropical Tuna Commission (IATTC), a multilateral body that manages tuna and other fish stocks in the Eastern Pacific, held its annual meeting Sept. 1-5 in Panama.
- Commission members agreed to shorten an annual fishing closure from 72 days to 64 days, which was in keeping with recommendations from the IATTC’s scientific committee.
- The members also agreed to move toward adoption, in 2026, of a long-term harvest strategy for bigeye tuna (Thunnus obesus).
- They didn’t adopt proposals to increase monitoring of longline tuna vessels and strengthen shark protection measures, due to resistance from East Asian members.
Indonesia’s giant Java seawall plan sparks criticism & calls for alternatives
- Indonesia has launched a massive new project on Java’s northern coast, framed as protection for millions of residents from worsening environmental threats.
- The plan has drawn sharp criticism from experts and activists who question its methods, costs and potential impact on vulnerable communities.
- Calls are growing for deeper public consultation and long-term solutions that go beyond quick fixes.
Photos documenting overfishing impacts in SE Asia win journalism award
A photojournalism series documenting the environmental and human impacts of overfishing in Southeast Asia has won the 15th Carmignac Photojournalism Award. Nicole Tung, a photographer based in Istanbul, Türkiye, spent nine months in Thailand, Indonesia and the Philippines documenting the fishing industry and the toll it’s taking on marine life, fishers and coastal communities. Fishing […]
Kafue River Transect
From its source in the wetlands near Zambia’s northwestern border, through the industrial zones of the Copperbelt, to where it plunges through a steep gorge toward the Zambezi, the Kafue River sustains some of Southern Africa’s richest ecosystems, vital to communities, wildlife, and energy production. Mongabay contributor Ryan Truscott joined an initiative exploring the river’s […]
Shrinking Mekong megafish underlines risks to the river, study finds
- A new study has found that the Mekong River’s largest freshwater fish are shrinking in size, with critically endangered species like the giant catfish and giant barb now averaging less than half their historical size.
- Researchers analyzed more than 397,000 samples of 257 species across Laos, Cambodia and Vietnam, finding that fish longer than 60 centimeters (2 feet) are shrinking fastest, while smaller species show little change.
- Overfishing, habitat loss, dam construction, sand mining, pollution and climate change are driving the decline, raising fears of collapse in one of the world’s most important inland fisheries.
- Scientists warn the trend mirrors global declines in large freshwater species, such as in the Amazon and Nile basins, but recent discoveries of massive fish like a 300-kg stingray show it’s not too late for recovery if urgent action is taken.
Indonesia’s Bajau fishers lament nickel mining’s marine pollution
For many members of the nomadic Bajau sea tribe on Indonesia’s Kabaena Island, growing up meant swimming and fishing in clear waters, just outside their homes built on stilts. However, in 2010, the water turned red, which the villagers blame on runoff from nearby nickel mining, Mongabay’s Hans Nicholas Jong reported in July. “Now, I […]
How will fisheries change in a hotter world? Experts share
- Fifty years from now, in 2075, global ocean temperatures are forecast to rise by between 2° and 5° Celsius (3.6° and 9° Fahrenheit). Warming is already reshaping fisheries worldwide, and even more dramatic changes are expected as fish largely move to cooler latitudes.
- These fish migrations will change ecosystem patterns and will likely have unexpected consequences even in places far from the fish themselves. They also may devastate fishing communities, both on an economic scale and a social one.
- However, there are potential solutions to avoid the most catastrophic effects for fishers and ecosystems alike, including setting aside some ecosystems as marine protected areas, changing fisheries management strategies and retraining communities to provide supplemental income.
Anchovy-rich diet linked to vitamin deficiency and deaths among salmon, study
A new study links widespread deficiency of vitamin B1, or thiamine, among California Chinook salmon to their deaths. This adds yet another challenge for this iconic species whose population is already imperiled by climate change, habitat loss and overfishing. Salmon serve a critical ecological role in the Pacific Northwest, transporting marine nutrients from the ocean […]
Upmarket fish maw trade in Singapore & Malaysia includes endangered species: Study
- A new study using DNA barcoding reveals that Singapore and Malaysia’s fish maw markets include species listed as vulnerable, endangered or critically endangered, many of which are poorly monitored and sourced from unmanaged fisheries.
- Researchers identified 39 species from 503 dried maw samples, including critically endangered large yellow croakers and European eels, highlighting the scale and complexity of this high value, underregulated trade.
- Experts warn that the trade poses a growing threat to marine biodiversity, and with nearly 30% of samples coming from species lacking IUCN assessments, it makes sustainability difficult to evaluate.
- Researchers and conservationists urge governments to expand CITES protections, enhance species monitoring, educate stakeholders, and improve international coordination to prevent more marine species from being pushed toward extinction.
Krill fishery in Antarctica shut down after record catch triggers unprecedented early closure
MIAMI (AP) — Officials have shut down early the remote krill fishery near Antarctica after trawling for the tiny crustacean — a vital food source for whales that also helps fight climate change — exceeded the seasonal catch limit for the first time. The unprecedented early closure of the fishery follows a report by The Associated Press last week […]
Evolution in overdrive as Baltic cod shrink due to fishing pressure, study shows
- The eastern Baltic cod has shrunk dramatically in size in recent decades due to rapid evolution — changes at the genetic level — caused by decades of intensive fishing, a new study says.
- Eastern Baltic cod, which are a distinct subpopulation of Atlantic cod (Gadus morhua), lost nearly half of their length and four-fifths of their weight from 1996 until 2019.
- It’s one of the first studies to show that a marine species has evolved in response to fishing pressure.
- An expert said the shrinking of the cod was “alarming,” and called on fisheries managers to work to protect fish biomass and size, given this new evidence of fisheries-induced evolution.
Conservationists raise sharks to restore reefs in waters around Thailand
- A new rewilding program aims to boost the local population of bamboo sharks in the waters of Khao Lak, Thailand.
- The species, classified as near threatened on the IUCN Red List, used to be abundant in the area, but has declined as a result of overfishing and habitat destruction.
- Since the project launched in 2018, with the support of luxury resorts in the area, it has released 200 bamboo sharks into the wild.
- A separate program that started in May 2025, is breeding leopard sharks, which are listed as endangered. They will be released in the waters off Phuket, and eventually the Gulf of Thailand.
With coral-rich Churna Island now an MPA, Pakistan takes baby steps on ocean protection
- In September 2024, Churna Island and the sea surrounding it became Pakistan’s second designated marine protected area, home to a variety of corals and serving as a nursery for fish.
- It followed the 2017 designation of the country’s very first MPA around Astola Island, a haven for coral, birds and sea turtles to the east.
- While Pakistan’s first two MPAs are small and have yet to be fully implemented, they represent baby steps in the country’s nascent effort to protect its marine environment.
- The country still has a long way to go to protect 30% of its ocean by 2030, as mandated by the United Nations Convention on Biological Diversity.
Two coasts, one struggle for octopus fishers battling overfishing and warming waters
- In Spain and Mexico, demand for octopus is up, but octopus populations are down.
- In both countries, artisanal octopus fishers are sticking to traditional fishing techniques while joining eco-certification schemes with tighter regulations, hoping to protect not just the cephalopod population, but their own livelihoods.
- But while this may offer a lifeline to the fishers’ economies, it may only work well for the octopus populations when all fishers in an area join in, experts say — and that’s not the case in Mexico, where illegal octopus fishing is rampant.
- Moreover, factors beyond fishers’ control, like warming waters, may affect the fishers and the octopuses alike.
First-ever assessment highlights threats to Atlantic cold-water corals
- A new study published in the journal Marine Biodiversity delivers the first global IUCN Red List assessments for 22 cold-water coral species in the Northeast Atlantic.
- More than 30% of the species are at risk of extinction due to bottom-contact fishing, habitat destruction and climate change, with white coral (Desmophyllum pertusum) listed as globally vulnerable.
- Experts say the findings highlight gaps in conservation, especially for deep-sea species often excluded from monitoring and protection efforts.
- The study’s release comes at a key moment, as international talks continue under the Beyond National Jurisdiction Treaty to improve high seas biodiversity protections.
Vanishing giants: The Indian Ocean’s biggest fish need saving (commentary)
- New research confirms the decline of predatory and large-bodied fishes in the western Indian Ocean due to overfishing, unregulated fishing practices and climate change.
- The lead author of a new paper published in the journal Conservation Biology argues that these fish must be protected to ensure healthier reefs, marine ecosystems and adjacent human communities.
- “This issue isn’t just about protecting fish, but also maintaining a healthy ecosystem, supporting a crucial food source for millions and sustaining the livelihoods of many coastal communities. If we act now, we can still turn the tide,” the author writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Endangered humphead wrasse gets a lifeline from facial recognition tech
- The endangered humphead wrasse, a reef fish that swims the seas from Africa to the South Pacific, is in high demand in mainland China and Hong Kong as a luxury culinary delicacy.
- Despite harvest limits, trading regulations and fishing bans, it’s overfished and illegally traded.
- Researchers in Hong Kong have developed a new AI-based photo identification smartphone app, Saving Face, to help enforcement officers identify individual fish using their unique facial patterns with just a photo.
- Researchers say they hope the app can address both illegal laundering of humphead wrasse and mislabeling of wild-caught fish as captive-bred; its developers say it can be tweaked to identify other species that have unique markings.
Seaweed farming as an eco-friendly alternative for Tanzanian fishing communities
Climate change, overfishing and habitat loss have caused a sharp decline in fish stocks around Pemba Island, off the coast of Tanzania. To find a new income from the sea, women from Pemba are turning to sustainable seaweed farming, Mongabay’s video team reported in May. Seaweed farming was introduced to the island in 1989. It […]
Glass eel smuggling booms despite bans, leaving species on the brink
- The illegal trafficking of critically endangered European glass eels continues to thrive, generating up to 3 billion euros ($3.5 billion) in peak years, with more than 1 million live eels seized in 2023 alone — mostly en route to East Asian aquaculture farms where they’re raised to maturity to produce the delicacy unagi.
- Europol describes the trade as a highly organized transnational crime involving smuggling, document fraud and money laundering, with sophisticated players using scientific expertise to keep smuggled eels alive during transit.
- Conservationists warn that removing juvenile eels from the wild disrupts their life cycle and ecosystem functions, worsening the species’ 90% population decline since the 1970s and threatening biodiversity in connected marine and freshwater systems.
- Experts call for stronger enforcement, improved monitoring, public awareness and habitat restoration to combat the trade and avert further ecological damage.
Tanzania’s Mafia Island eyes sea cucumber farming to prevent extinction
Residents of Mafia Island in Tanzania don’t really eat sea cucumber; they call it jongoo bahari, or “ocean millipede” in Swahili. But sea cucumbers are a prized delicacy in East Asia, where demand has fueled a black market for the spiny sea creatures, Mongabay’s Ashoka Mukpo reported in May. A kilogram of dried sea cucumbers […]
In Nepal, northernmost sighting of Eurasian otter raises hope, concerns
- The northernmost Eurasian otter sighting in Nepal was recorded in the Karnali River, raising hopes for the species’ range expansion. But as the animal was found dead in a fishing net, conservationists highlight challenges to the species’ conservation.
- Researchers emphasize the rarity of such sightings in high-altitude, remote areas like Humla, where otters had been considered cryptic or absent for decades.
- The discovery builds on a series of recent sightings across Nepal, including in urbanized Kathmandu Valley, suggesting a wider distribution than previously known.
- Threats to otters include overfishing, poaching, hydropower projects, sand mining and net entanglement, all of which imperil not just the Eurasian otter but also Nepal’s two other otter species.
Tuna fishing devices drift through a third of oceans, harming corals, coasts: Study
- Drifting fish aggregating devices (dFADs) are floating rafts with underwater netting used by fishing vessels to attract tuna.
- A recent study estimated that between 2007 and 2021, 1.41 million dFADs drifted through 37% of the world’s oceans, stranding in 104 maritime jurisdictions and often polluting sensitive marine habitats.
- Strandings were most frequent in the Indian and Pacific oceans, with the Seychelles, Somalia and French Polynesia accounting for 43% of cases; ecosystem damage and cleanup costs fall on local communities.
Community-led system boosts fisheries in a corner of fast-depleting Lake Malawi
Lake Malawi’s fish stocks are declining, but one community stands apart: around Mbenje Island, a traditional fisheries management plan has ensured thriving fish populations for generations, Mongabay contributor Charles Mpaka reports. Landlocked Malawi is highly dependent on the lake, which supplies 90% of the country’s fish catch; more than 1.6 million people rely directly or […]
There’s something fishy about ‘blue economy’ proposals for sustainable marine management (commentary)
- Proposals for developing a “blue economy” emerged in the 2010s as a vision for sustainable ocean development, as communities across the world grappled with challenges of declining ocean health, economic crises and stalling development outcomes.
- Central to their appeal is a promise to transform human interactions with the ocean, promoting a shift toward ecological health, improved livelihoods and job creation, but too often these proposals have been driven by large nations and interests, rather than small coastal nations whose prosperity is most heavily linked with marine ecosystems.
- The author of this commentary warns that this sustainable ocean vision may be operating as a tool for pacifying demands for sustainable and equitable ocean relations, rather than as one that advances them.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Warming seas and illegal trawlers threaten West Africa’s fishing future, study warns
A new paper paints a grim picture for the future of fishing communities in the Gulf of Guinea along coastal West Africa. Faced with increasing ocean warming and declining fish stocks, fishing communities in Ghana, Côte d’Ivoire and Nigeria struggle to survive. The paper’s authors advocate for income diversification among fishing communities as a critical […]
Tuna talks bring wins for Indian Ocean sharks, but more needed, experts say
- At the most recent round of Indian Ocean tuna talks, countries adopted measures to curb shark finning, expand the scope of bans that prohibit fishers from holding on to sharks caught as bycatch and restrict the use of harmful fishing gear.
- Conservationists said the measures will reduce the unwanted capture, or bycatch, of sharks that get hauled in by fishers targeting tuna and tuna-like species.
- A complete retention ban is already in place for oceanic whitetip sharks and thresher sharks in the Indian Ocean, and it will most likely be extended to whale sharks.
- A partial ban on retaining shortfin mako, an overfished endangered species, will take effect in 2026. However, scientists fear the measures to save the Indian Ocean shortfin mako may not be enough.
Protecting coastal waters may be the best investment you’ve never heard of, says Kristin Rechberger
- In this interview, Kristin Rechberger—founder of Dynamic Planet and a Mongabay board member—discusses Revive Our Ocean, a new initiative empowering coastal communities to establish marine protected areas (MPAs) that benefit both nature and livelihoods.
- With only 3% of the ocean fully protected and the 2030 “30×30” target looming, Rechberger argues that waiting on governments isn’t enough; community-led efforts are crucial to scaling marine conservation rapidly and equitably.
- Drawing on a decade of experience creating large offshore marine reserves, Rechberger is now focusing on coastal regions where local communities have a direct stake in healthy seas—but often lack the legal authority, tools, or support to act.
- She emphasizes that marine protection is not only ecologically effective but economically smart, citing examples like Spain’s Medes Islands Reserve and Mexico’s booming dive tourism as models for prosperity through conservation.
Under Trump, US retreats from global fisheries and oceans leadership
- The United States has long been an international leader in fisheries and oceans science, with influence at international fora that it has sometimes wielded to support conservation measures and crackdowns on illegal fishing.
- However, U.S. influence at fisheries and oceans fora appear to be waning during the second Trump administration, which could compromise fisheries health and marine conservation, experts say.
- The administration, which took office Jan. 20, has begun to institute a program of budget and staff cuts at U.S. departments and agencies that work on fisheries and oceans governance, while turning away from or undercutting multilateral organizations.
Southeast Asia’s fisheries thrive despite decades of overfishing warnings: Study
- Overfishing in Southeast Asia’s coastal waters is a long-standing concern, but recent research suggests a more optimistic outlook, with 43% of marine stocks classified as underfished — 3.6 times higher than the global average.
- The study, covering stocks across the Indian and Pacific Oceans, highlights the region’s relatively abundant fisheries, particularly among pelagic species, 63% of which are underfished.
- Southeast Asia’s fisheries production surged by 7.1 million metric tons from 1993 to 2022, the largest increase globally, with Indonesia, Vietnam and Myanmar as major contributors.
- The research underscores the importance of small-scale artisanal fisheries that use nonselective methods to target multiple species, and co-management frameworks to maintain production and sustainability.
Indian trawlers leave Sri Lankan small-scale fishers a ravaged, bereft sea
- Bottom trawlers from India’s southern state of Tamil Nadu have been encroaching Sri Lanka’s northern waters for years, carrying out destructive fishing practices that have caused serious depletion of fish stocks and damaged marine habitats.
- Meanwhile, Sri Lanka’s local small-scale fishers continue to struggle due to reduced catches, destruction of their fishing nets and financial loss while being forced to fish in limited nearshore areas or abandon fishing temporarily to avoid conflict with the trawlers.
- In this political bone of contention, Tamil Nadu has been demanding reclamation of Katchatheevu — an uninhabited island between India and Sri Lanka — to gain unrestricted fishing rights, and the past bilateral promises to phase out bottom trawling have gone unfulfilled.
- Sri Lanka banned bottom trawling in 2017 and now needs to take specific actions to prevent illegal bottom trawling in its northern waters to avoid the risk of fisheries there from collapsing.
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.
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.
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.
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.
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.
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 […]
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 […]
Mexican fishers relocate in wake of sea level rise, raising job concerns
- In the southern Mexican state of Tabasco, most residents of the El Bosque community have been relocated after their homes were destroyed by coastal erosion.
- Community members have expressed concern about job security, as the new site is 12 kilometers (7.4 miles) away from the sea and residents cannot as easily fish, which they depend on for their livelihoods.
- While planned relocation has emerged as a critical strategy to protect those impacted by climate change, reports have shown relocation does not always reduce socioeconomic pressures.
- Although fishers from El Bosque are concerned about the impact of the relocation on their livelihoods, some see it as an opportunity for younger generations to seek alternative livelihoods and better opportunities.
Fishing boats spotted competing with whales in Antarctica for krill
Nearly all of Antarctica’s iconic wildlife, from penguins to seals and whales, depend on krill, tiny crustaceans that make up the base of the food chain. Krill are also sought after by humans, who scoop them up using massive fishing boats, potentially putting whales in danger, scientists warn. The fishing boats and whales are “going […]
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 […]
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.
South Australia bans fishing of many sharks and rays in its waters
The state of South Australia has banned fishing of several endangered or critically endangered sharks and rays in its waters. In a media release dated Dec. 11, the state government said the new rules prohibit both recreational and commercial fishing of critically endangered species such as the whitefin swellshark (Cephaloscyllium albipinnum), oceanic whitetip shark (Carcharhinus […]
‘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.
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.
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.
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.”
Peruvian fishers help red sea urchins recover from overfishing
- For 20 years, fishers from the district of Marcona, on Peru’s southern coast, have been recovering populations of red sea urchin, thanks to an alliance with the government.
- According to a monitoring study by the Peruvian Institute of the Sea, there are more urchins in the area where Marcona fishers work than in other areas.
- Part of the success is rooted in the spatial management of coastal areas that the artisanal fishers’ associations are applying; they are pioneers of this practice in the country.
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.
Population crash means African penguins are now critically endangered
Africa’s only resident penguin species is now officially critically endangered, according to a recent assessment by the International Union for Conservation of Nature (IUCN). Over the past century, the African penguin (Spheniscus demersus) has suffered precipitous declines in its population. In the mid-1950s, there were an estimated 141,000 breeding pairs of African penguins, or 282,000 […]
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.
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.
Cambodian fishers-turned-citizen scientists monitor marine mammal deaths
- In Cambodia, the NGO Khmer Ocean Life has trained residents of coastal fishing communities about threats to marine mammals so they can participate in a citizen scientist network aimed at tracking bycatch and strandings.
- At least 10 species of marine mammals are commonly found in Cambodia, including dugongs (Dugong dugon), Indo-Pacific finless porpoises (Neophocaena phocaenoides), Indo-Pacific humpback dolphins (Sousa chinensis) and endangered Irrawaddy dolphins (Orcaella brevirostris); all of these species face an array of threats, including coastal development and unsustainable fishing practices.
- Bycatch is the biggest threat facing marine mammals globally, according Sarah Tubbs, Khmer Ocean Life’s co-founder and co-director, and coastal marine mammals face greater threats due to their proximity to fishing activities.
- Currently, data on marine mammal bycatch and strandings are lacking in Cambodia; the citizen scientist network will provide real-time insights into where bycatch mitigation efforts are most needed.
Celestún refuge fights illegal fishing & helps revive species in Mexico’s Yucatán
- In 2019, the Celestún fishing community in Yucatán, Mexico, established a 324-square-kilometer (125-square-mile) Fishing Refuge Zone (FRZ), the largest in the Gulf of Mexico.
- The area was created in response to the overfishing of sea cucumbers, a species that had been in rapid decline, which caused social strife in the community.
- Local fishers have been trained to monitor the refuge to help the species recover and protect other species of commercial interest, like octopus and lobster. The participation of women has been an important part of the process, as they help lead community monitoring efforts.
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 […]
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.
Argentina weighs new MPA to curb international fishing frenzy in ‘Blue Hole’
- Creation of the “Blue Hole” marine protected area in the South Atlantic Ocean would protect thousands of square kilometers of seafloor from bottom trawling and require better working conditions on vessels fishing there. But the bill that would do so has stalled in Argentina’s Congress for years and will expire in November.
- The marine protected area would cover 148,000 square kilometers (57,100 square miles) of Argentina’s continental shelf, where global fishing fleets carry out unregulated fishing, including bottom trawling.
- The Blue Hole protected area would protect the seabed from bottom trawling but continue to allow fishing in the water column above it.
- Ratification of a U.N. treaty could enable Argentina to protect the area from all forms of fishing in the future.
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.
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.
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.
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.
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.
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.
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.
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.
Indonesian activist freed in hate speech case after flagging illegal shrimp farms
- Indonesian environmental activist Daniel Frits Maurits Tangkilisan has had his sentence overturned on appeal, in a case that saw him charged over a Facebook post highlighting illegal shrimp farms operating in a marine protected area.
- The appeals court held that while the post constituted hate speech, as a lower court had ruled, it was made in defense of the constitutional right to a healthy environment.
- Three fellow activists face prosecution under the same charges for posting a video of their opposition to the polluting shrimp farms in Karimunjawa National Park, an ostensibly protected area.
- The case is one of hundreds prosecuted under the widely panned online speech law that activists and rights experts say has been exploited by the state and business interests to silence critics.
Undercover in a shark fin trafficking ring: Interview with wildlife crime fighter Andrea Crosta
- Worldwide, many of the key players in wildlife trafficking are also involved in other criminal enterprises, from drug smuggling to human trafficking and money laundering.
- In an interview with Mongabay, Andrea Crosta, founder of Earth League International, talks about the group’s new report on shark fin trafficking from Latin America to East Asia and the concept of “crime convergence.”
- International wildlife trafficking, including the illegal trade in shark fins, is dominated by Chinese nationals, Crosta says.
- Since smuggling routes often overlap and criminal groups frequently work together across borders, Crosta calls for field collaboration among countries and law enforcement agencies to fight wildlife crime, the world’s fourth-largest criminal enterprise.
Twilight zone fishing: Can we fish the ocean’s mesopelagic layer?
- Fishing experts are looking for ways to fish in the mesopelagic zone, a layer of water that stretches from 200-1,000 meters (660-3,300 feet) beneath the surface, which has, thus far, remained relatively unexploited.
- Many challenges stand in the way of making mesopelagic fishing a reality, such as the difficulties of finding and capturing mesopelagic fish, and processing them into usable products.
- Yet experts are working to overcome these obstacles, with one suggesting that mesopelagic fishing could begin in the next few years.
- Conservation experts have expressed concern about the possible start of mesopelagic fishing, arguing that it could cause environmental problems.
Indonesia resumes lobster larvae exports despite sustainability, trade concerns
- The Indonesian government will resume a controversial policy of exporting lobster larvae, initially just to Vietnam, in exchange for investment in its own lobster-farming industry.
- The ban has met with controversy since it was introduced in 2016; a subsequent attempt to lift it failed after the fisheries minister at the time was arrested for taking bribes to issue export permits.
- The current minister says the lifting this time around is based on pragmatic considerations, with law enforcement efforts failing to stop the smuggling of lobster larvae.
- Critics say the move will benefit Vietnam more than it will Indonesia, given that the former’s far more advanced lobster-farming industry generates far more value from the sale of mature lobsters than Indonesia ever could from the sale of larvae.
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.
No answers for Ghanaian fishery observer’s family months after suspected death
- Samuel Abayateye, a 38-year-old father of two, was working as a fisheries observer when he was reported missing from his assigned vessel in October 2023.
- After a body missing its head, forearms and feet that Abayateye’s family says closely resembled him washed ashore in December, the Ghana Police Service opened an investigation.
- Five months later, Abayateye’s family said they still haven’t received any information from the authorities investigating the case, or the results of a DNA test to confirm the identity of the body.
- A fisheries observer told Mongabay the case has sown fear among observers appointed to monitor and report on illegal fishing in fleets operating in Ghana. Fishing industry experts say the case highlights the dangers faced by observers, whose job is critical to ensuring fishing vessels comply with the law.
Who was Samuel Abayateye, the fishery observer missing in Ghana
ANYAMAM, Ghana — In October 2023, Samuel Abayateye, a 38-year-old fishery observer, went missing in Ghana. This unsettling event is part of a troubling pattern, as disappearances of fishery observers in Ghanaian waters have occurred before. In this video, Mongabay travels to Anyamam, Samuel’s home village, to speak with his family and uncover more about […]
Fewer fish and more rules lead to illegal catches, Italian fishers say
- The line between legal and illegal fishing in the waters off Italy’s Calabria region is often blurred, with fishers blaming stringent top-down regulations for constricting their traditional practices.
- The issue is further muddied by the presence here of the ‘ndrangheta or Calabrian mafia, which investigations have shown is involved in the fish trade and also uses it as cover for illicit activities such as drug smuggling.
- The Mediterranean Sea is experiencing a decline in fish stocks, ranging from 60-90% depending on the species, with the NGO Sea Shepherd Italia blaming illegal fishing for environmental damage.
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.
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.
Indonesian court jails environmentalist for flagging illegal farms in marine park
- An Indonesian court has sentenced an environmental activist to seven months in jail for a Facebook post in which he criticized the growing problem of illegal shrimp farms operating inside a marine park.
- The court found that Daniel Frits Maurits Tangkilisan had “created unrest” because of his post, under a controversial 2008 law on online speech that’s been widely used to silence environmental and human rights activists.
- Three other activists face similar charges in the case, which centers on their efforts to highlight the presence of illegal shrimp farms inside Karimunjawa National Park, which is supposed to be a protected area.
- Fellow rights activists have lambasted the ruling against Daniel, saying it sets a dangerous precedent for exploitation of the justice system to silence and criminalize individuals.
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.
Indonesian activists face jail over FB posts flagging damage to marine park
- Four environmental activists in Indonesia face up to 10 months in jail for “hate speech” after complaining online about the proliferation of illegal shrimp farms inside a marine park.
- Karimunjawa National Park, which is supposed to be a protected area, has seen the number of such farms inside its borders proliferate in recent years, which groups like Greenpeace have linked to ecosystem degradation.
- Daniel Frits Maurits Tangkilisan is the first of the four members of the #SaveKarimunjawa movement to go to court; a verdict in his case is expected on April 4.
- All four men have been charged under a controversial 2008 law on online speech, which critics say has been abused vigorously by the Indonesian state to stifle dissent and opposition.
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.
Report: Rising slaughter of small whales and dolphins threatens ocean balance
- Killings of small whales, porpoises and dolphins are rising, with more than 100,000 of these marine mammals slaughtered each year, according to a new report from German and British NGOs.
- Many regions report increased catches driven by demand for dolphin meat as food and shark bait in areas impacted by economic crisis and dwindling fish stocks.
- Failure to address unsustainable exploitation of small cetaceans exacerbates ecological imbalance and heavy metal toxicity risks to humans who eat them, according to the report.
- Insufficient legislation and enforcement remain critical issues, according to the report, which calls for international collaboration and stronger protection measures.
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.
With drop in illegal fishing comes rise in piracy, study in Indonesia finds
- Indonesia’s crackdown on illegal fishing is driving an increase in maritime piracy, a new study shows.
- In recent years, the government has taken harsh measures against illegal fishers, including banning foreign fishing vessels from its waters, and blowing up those it seizes.
- However, researchers say the crackdown’s success, without addressing the drivers of illegal fishing, including poverty, “can inadvertently shift effort from fishing to piracy.”
- Illegal fishing costs an estimated $3 billion in lost revenue for Indonesia, the world’s second-biggest producer of wild-caught seafood.
No sea change on marine policy from candidates as Indonesia heads to polls
- None of the three candidates running in Indonesia’s Feb. 14 presidential election have presented meaningful policy changes for the country’s coastal communities and marine resources, observers say.
- Indonesians are voting in the biggest single-day election in the world, but the failure by candidates to prioritize maritime issues is a major omission for the world’s biggest archipelagic country.
- Observers say the interests of fishing communities continue to be subordinated to those of industry and developers when it comes to competition for space and resources, and that none of this looks set to change under any of the three candidates.
- They also note that issues such as poverty in coastal areas, threats to marine ecosystems, and the marginalization of coastal communities persist despite the significant role these communities play in Indonesia’s fisheries sector.
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.
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.
From exporting coral to restoring reefs, a Madagascar startup rethinks business
- After her father died, Jeimila Donty took over her family’s coral export business and shifted its focus to conservation, creating Koraï.
- Donty is part of a young “pro-climate” generation that’s keen to incorporate the environment into business models.
- Koraï plants corals in Madagascan waters on behalf of other companies as part of their corporate social responsibility (CSR) commitments.
- The business is ambitious and faces challenges, such as recruiting workers and a lack of political support.
Cambodia sea turtle nests spark hope amid coastal development & species decline
- Conservationists in Cambodia have found nine sea turtle nests on a remote island off the country’s southwest coast, sparking hopes for the critically endangered hawksbill turtle (Eretmochelys imbricata) and endangered green turtle (Chelonia mydas).
- It’s the first time sea turtle nests have been spotted in the country in a decade of species decline.
- Two nests have been excavated to assess hatching success; conservationists estimate the nests could hold as many as 1,000 eggs.
- Globally, sea turtle populations are declining, largely due to hunting for food and the animals’ shells, used in jewelry; other threats to sea turtles include tourism development, pollution and climate change.
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.
Report: Human tragedy stalks the prized Honduran lobster industry
- The Caribbean spiny lobster (Panulirus argus) is a coveted delicacy, with Honduras exporting $46.7 million worth of the shellfish in 2019, mainly to the U.S.
- But its flourishing trade comes at the expense of the Indigenous Miskito community living along Honduras’s Atlantic coast, according to an investigation published in December by nonprofit news outlet Civil Eats.
- Hundreds of Miskito lobster divers have died, and thousands more are injured or have become paralyzed in pursuit of the lobsters, the report noted.
- So far, efforts at reforming the Honduran lobster fishery have failed to adequately address the divers’ situation, according to the investigation.
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.
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.
Indonesia offers lobster larvae exports to Vietnam in exchange for investment
- Indonesia is seeking investment from Vietnam to develop Indonesia’s fisheries sector, especially the lobster farming industry, the country’s fisheries minister said during a visit to Hanoi.
- In exchange, Indonesia could supply up to 300 million lobster larvae to Vietnam and would stop seizing Vietnamese fishing boats encroaching into Indonesian waters, instead just turning them back.
- Jakarta banned exports of lobster larvae in 2016 to prevent the overharvesting of wild population from the country’s rich waters, but smuggling remains rampant.
- Despite concerns about potential harm to the domestic aquaculture industry, the government plans to finalize a decree to resume exports, citing the economic benefits and potential to reduce smuggling.
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.
Finance and support are key to fishers adopting eco-friendly gear, study shows
- Access to financing, the support of a peer group, and a general awareness of environmental problems are all factors that make it more likely a fisher will switch to using eco-friendly gear, a new study shows.
- The findings come from a three-month survey of nearly 650 blue swimming crab fishers on the north coast of the Indonesian island of Java.
- It found that those who made the switch also enjoyed significantly higher production and profitability, while also reducing their catch of egg-bearing female crabs, thus helping the sustainability of stocks.
- The study authors say these factors should provide valuable insights for fisheries policymakers in Indonesia and other less-industrialized countries.
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.
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.
Could mugger crocodiles be brought back from regional extinction in Bangladesh?
- Once, mugger crocodiles (Crocodylus palustris) were common in Bangladesh’s major rivers, including the Padma, Jamuna, Meghna and most of their tributaries, but the species is thought to have gone extinct in the country due to unchecked poaching for its prized skin.
- Although the IUCN in 2000 declared the mugger regionally extinct in Bangladesh, three adult muggers were recovered from the country’s river and water bodies in only 11 days, Oct. 17-28 this year.
- The crocodiles were taken to the Karamjol Crocodile Breeding Centre in Khulna, and authorities are working on how muggers could be brought back to nature by increasing their population through captive breeding.
- Experts suggest establishing a safe zone for the crocodiles in the upper Padma River.
‘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.
Indonesia delays enforcement of widely panned fisheries policy
- The Indonesian government has pushed back the implementation of a new fisheries policy based on catch quotas amid near-universal criticism from stakeholders.
- The fisheries ministry said the year-long delay would allow more time to prepare the fundamental infrastructure, but some observers speculated it was likely also linked to political factors.
- The quota-based fisheries management policy, introduced in March this year, will have affected industrial, local and noncommercial fishers, while small fishers are exempted from the quota.
- The fisheries ministry, however, said it would use the extended time to increase efforts for public outreach, education and gaining support for the implementation of the new policy.
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.
With Indonesia’s new fishing policy starting soon, fishers still mostly unaware
- Indonesia is scheduled to enforce a new fisheries policy at the start of the new year, but new reports have highlighted persistent inadequacies in the strategy.
- The office of the Indonesian Ombudsman says the quota-based fisheries management policy in general lacks accountability and transparency, including broader consultation with fishing communities.
- A separate report from Destructive Fishing Watch (DFW) Indonesia, an NGO, similarly found that many fishers had very limited awareness of the regulation changes and that existing fisheries infrastructure was inadequate to support the new strategy.
- Both organizations have called on the fisheries ministry to boost its efforts in public outreach about the new policy and ensure infrastructural readiness at all levels of government in the short time remaining before the policy goes into force.
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.

Indonesia welcomes new Singapore regulation to help curb lobster smuggling
- A new reexport regulation in Singapore could help stem the smuggling of lobster larvae from neighboring Indonesia.
- The city-state is a key destination for the contraband and a transit point for lobster larvae reexported to third countries like Vietnam and China.
- Under the new regulation, reexporters in Singapore will have to get health certificates for live animals from the country of origin, which in theory should be impossible for smugglers.
- Indonesian authorities have cautiously welcomed the plan, but say both countries must work more closely on the long-running problem.
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.
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.

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.
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.
Key Indonesian fish populations depleted & new assessments needed, study shows
- The wild populations that sustain a significant Indonesian fishery are more depleted than the government had estimated, as highlighted by a recent scientific study.
- The authors have called for a reevaluation of the method used to assess fish stocks to address the overexploitation of these populations.
- The Indonesian deep-slope demersal fisheries have helped position Indonesia to be the world’s second-largest exporter of snapper species.
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.
Sumatran Indigenous seafarers run aground by overfishing and mangrove loss
- Many among Indonesia’s Duano Indigenous community have hung up their fishing nets in response to recent environmental and economic shifts.
- A study published in October found that intact mangroves were associated with up to a 28% increase in fish and shellfish consumption among coastal communities.
- Duano elders say young people from the community are increasingly retiring from the community’s traditional livelihood to take up poorly paid casual work.
Indonesia renews effort to resume controversial lobster larvae exports
- The Indonesian government is drafting a new policy that could allow the resumption of lobster larvae exports, which were banned in 2016 to prevent overharvesting of wild stocks.
- The fisheries ministry says a resumption is necessary to boost local fishers’ earnings and develop the domestic aquaculture industry.
- However, critics say the new policy mirrors a previous attempt to resume exports in 2020, which spawned a corruption scandal that led to the fisheries minister at the time being jailed.
- The ministry says this time around the policy will be monitored and enforced more strictly, although questions still remain over how sustainably lobster larvae can be harvested from the wild.
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.
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.
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.
Small-scale fishers in Indonesian isles flag use of banned net by outsiders
- Fishers on a group of small islands in the Java Sea are calling for a crackdown on larger boats using a banned type of seine net in their waters.
- The Masalembu Islands, which lie in one of the most heavily trafficked fishing zones in Indonesia, have frequently seen boats from elsewhere encroach into the near-shore zone that’s reserved for small-scale traditional fishers.
- The local fishers say these bigger boats typically use a cantrang net, banned by the fisheries ministry but still in widespread use amid a lack of law enforcement.
- The fishers have petitioned the government to clearly designate the traditional fishing zone that should be strictly off-limits to these cantrang boats.
Indonesia, Singapore to work more closely against lobster larvae smugglers
- Indonesia has called for Singapore’s commitment to shut its borders to illegal exports of lobster larvae.
- Indonesia has since 2021 banned exports of wild-caught lobster larvae, but Singapore still permits their import, serving as both a key market and a regional trading hub.
- Lobsters are among Indonesia’s top fisheries commodities, but the illegal export of larvae and baby lobsters costs the country billions of rupiah in lost revenue and threatens the declining wild population of the shellfish.
- The fisheries ministry puts the latest estimate of potential wild lobster stock in Indonesian waters at 27 billion, but many of the officially sanctioned fishing zones are overfished, with the rest being harvested at maximum capacity.
‘All will be well’: Q&A with Kenyan fisher turned coral gardener Katana Ngala
- Once a fisherman, Katana Ngala has been restoring corals near his home in Kuruwitu, Kenya, for more than 20 years.
- Early on, the area’s coral was degraded due to destructive fishing practices and coral bleaching, and he and other fishermen were experiencing diminished catches.
- Now the coral and fish are flourishing in the area, which the local community set aside as a no-fishing zone.
- Ngala spoke about the changes he’s seen in the coral garden over time and how he shares his commitment to the sea with fishers, students, scientists and the wider community in an interview with Mongabay at his seaside coral workshop.
Indonesian fishers not biting at new policy perceived as undermining them
- The Indonesian fisheries ministry issued a decree earlier this year introducing a quota-based fisheries management policy aimed at maximizing state revenue from the sector.
- A new study, however, has found that the new policy is unpopular with fishers, who say it reduces the role of local authorities and fishing communities.
- Local stakeholders’ responses also suggest the policy only benefits large-scale investors and commercial fishers, who are perceived to have a high negative impact on the environment.
- Indonesia’s fisheries sector plays a major role in the global seafood supply, with the country home to some of the world’s richest marine biodiversity.
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.
Kenyan fishers put new twists on an age-old marine conservation system
- Over the past two decades Kenyan fishing communities have been setting up no-fishing zones called tengefus, Swahili for “set aside.”
- The idea was inspired by the fishing habits of their forebears, who prior to colonization established seasonal fishing closures to ensure plentiful harvests.
- Today there are 22 tengefus in various stages of development in the country, some more successful than others.
- Successful tengefus have seen fish populations and coral cover increase, and they’ve established tourism enterprises that fund community initiatives. To work, experts say tengefus need support from communities, donors and the government.
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.
‘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.
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.
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.
Sharks deserve our appreciation and protection (commentary)
- Shark Awareness Day is celebrated on July 14 every year: though widely feared and sometimes vilified, sharks actually play a key role in ocean health and are rarely a threat to humans.
- “We must all take action to protect sharks, and raising awareness and educating others about the importance of sharks is a great spot to start,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
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.
Bangladesh ramps up freshwater fish conservation in bid for food security
- Bangladesh is reviving 39 native freshwater fish species through hatchery breeding, in an effort to secure stocks of commercially important fish.
- A quarter of the freshwater fish found in Bangladesh are threatened with extinction, according to a 2015 assessment, largely as a result of habitat loss, overfishing and pollution.
- In response to the decline, the Bangladesh government is breeding several species in captivity and distributing the fry for free to fish farmers.
- Bangladesh produces 4.6 million metric tons of fish a year, and is the No. 3 producer of freshwater fish globally.
Brazil claims record shark fin bust: Nearly 29 tons from 10,000 sharks seized
- Brazilian authorities announced the seizure of almost 29 tons of shark fins, exposing the extent of what they described as illegal fishing in the country. The previous record for the largest seizure reportedly took place in Hong Kong in 2020, when authorities confiscated 28 tons of fins.
- The seized fins, reportedly destined for illegal export to Asia, came from an estimated 10,000 blue (Prionace glauca) and anequim or shortfin mako (Isurus oxyrinchus) sharks, according to Brazil’s federal environmental agency IBAMA. Shortfin makos recently joined the country’s list of endangered species.
- IBAMA is filing infraction notices and fines against two companies over the seized fins. Other firms remain under investigation for illegal shark fishing related to the seizure, according to the agency.
- Through detailed analyses of the origins of these fins, an IBAMA statement said the agency identified a wide range of irregularities, including the use of fishing authorizations for other species and the use of fishing gear to target sharks.
Indonesia to expand ‘smart fisheries’ program aimed at empowering communities
- Indonesia will expand its smart fisheries village program, aiming to empower fishing communities to boost their productivity, achieve sustainability standards, and improve their overall economic welfare.
- Twenty-two fishing communities are enrolled in the initial batch of the program, which will focus primarily on fisheries, but also look to improve community welfare through tourism, public health interventions, financial literacy, and other initiatives.
- The participating communities are involved in catching or farming a wide range of seafood and other products, from octopus and tilapia to shrimp and organic salt.
- The fisheries sector employs about 12 million Indonesians, with most of the fleet today, about 650,000 vessels, operated by small-scale and traditional fishers.
Indonesia to cut tuna harvest in bid for more sustainable fishery
- Indonesia will reduce its overall tuna catch by 10% over the course of three years, citing unsustainable current levels of fishing.
- The government is also pushing for more tuna fisheries in Indonesia to obtain sustainable certification and eco-labeling, as part of wider efforts to show that it can manage the species within its waters.
- Fisheries experts have welcomed the move to protect the world’s tuna populations, but say other countries in the region should also be encouraged to reduce their catch to make it effective.
- Indonesia catches more tuna than any other country, accounting for about 16% of the world’s total tuna supply.
Climate change, human pressures push Bangladesh’s ‘national fish’ into decline
- Bangladesh’s all-important hilsa fishery is declining amid pressures from human-driven factors and climate change, experts and authorities warn.
- The fish, Tenualosa ilisha, contributes around 12% of the total fish catch in Bangladesh, and the fishery employs at least 2.5 million people across the country.
- Several government conservation initiatives, including declaring six hilsa sanctuaries and two fishing bans during the year, have helped boost production in the past two decades.
- However, pressures persist, including rising salinity levels in the rivers where the fish spawn, discharge of pollution and agricultural runoff, and disruptions to water flow as dams are built upstream.
Several reef sharks at greater threat of extinction than thought, study shows
- A new study found that five key reef shark species — gray, blacktip, whitetip and Caribbean reef sharks, and nurse sharks — declined by 60-73% worldwide.
- It also indicated that all five species would qualify as endangered on the IUCN Red List.
- Early results from the study were used to escalate the status of two of the five species to endangered, but the others are still considered to have a lower extinction risk.
- The study also showed that well-governed or protected reefs had healthier shark populations.
Indonesia looks into tuna farming to boost aquaculture, reduce overfishing
- Indonesia is developing tuna farming in the country’s bays in an effort to boost its aquaculture sector and ease the pressure on its world-leading marine tuna fishery.
- The fisheries ministry said it was consulting with international fisheries experts about implementing tuna farming.
- Indonesia’s archipelagic waters are key fishing grounds for several many tuna species, as well as spawning grounds for the fish.
- Indonesia’s tuna fisheries is an important source of livelihood for coastal communities and a key source of food for consumers around the world.
Can an app help Liberian artisanal fishers fight illegal fishing?
- Small-scale fishers in Liberia are using a data collection platform to document cases of illegal activity at sea.
- Artisanal fishers have long borne the brunt of illegal, unreported and unregulated (IUU) fishing, some of it occurring within an inshore exclusion zone that extends 6 nautical miles from shore.
- Through the use of a mobile app called DASE, released by the NGO Environmental Justice Foundation, local fishers can geotag images and videos of incidents at sea and submit them to the National Fisheries and Aquaculture Authority for verification and possible investigation.
- Though the app has not resulted in any prosecutions yet, fishers say it is having a deterrent effect on illegal activities.
A Southeast Asian marine biodiversity hotspot is also a wildlife trafficking hotbed
- A recent report documents the seizure of 25,000 live animals and more than 120,000 metric tons of wildlife, parts and plants from the Sulu and Celebes seas between 2003 and 2021.
- The animals trafficked include rays, sharks and turtles, mostly between Indonesia, the Philippines and Malaysia, for which the region forms a maritime border zone.
- The people of the Sulu and Celebes seas region have strong transboundary cultural and trade links, prompting experts to call for enhanced international cooperation in enforcement efforts.
U.S. says Mexico failed to uphold international treaty protecting vaquita porpoise
- The United States said the government of Mexico has failed to stem the illegal harvest and commercial export of totoaba, which has directly impacted the vaquita.
- The vaquita has dwindled to around just 10 specimens in recent years, the result of getting caught in gillnets targeting totoaba, whose swim bladder is treasured on the Chinese black market.
- US law allows for an embargo on wildlife trade when a country isn’t doing enough to combat illegal activity. However, it isn’t clear that President Joe Biden will take that step.
As one Indian Ocean tuna stock faces collapse, nations scramble to save others
- Indian Ocean Tuna Commission members failed to make progress on key measures to protect declining yellowfin tuna (Thunnus albacares), like reducing annual catches and limiting the use of harmful fish aggregating devices (FADs), during their annual meeting.
- Although the commission declared yellowfin tuna overfished in 2015, to date, the intergovernmental regional management body has failed to curb overfishing, bringing the stock closer to collapse.
- Objections from the European Union helped nullify an ambitious plan adopted by the IOTC in February to limit the use of drifting FADs: Objecting parties don’t have to implement the measure, and the EU tuna fleet, which has historically pulled in the largest yellowfin tuna catches in the Indian Ocean, is the biggest deployer of DFADs in the region.
- The commission declared the Indian Ocean bigeye tuna (T. obesus) stock overfished in 2022, and at its meeting in May parties agreed to a 15% reduction from 2021 levels in the permitted annual catch; they also adopted protective measures for seabirds and marine mammals at the meeting, but not for sharks.
‘Chasing giants’: Q&A with megafish biologist and author Zeb Hogan
- Earth’s freshwater ecosystems are among the most at risk from human-induced threats including overfishing, dam building, pollution and climate change.
- But biologists know relatively little about the animals that live in the murky depths of our rivers and lakes, perhaps least of all about some of their largest inhabitants.
- In a new book, fish conservation biologist Zeb Hogan teams up with journalist Stefan Lovgren to get to the bottom of a curious question: What is the world’s largest freshwater fish?
- An exploration of the world’s freshwater ecosystems from Australia to the Amazon, “Chasing Giants” also looks into the range of threats giant fish face the world over and what scientists, policymakers and the public can do to support their conservation.
Indigenous women in Colombia protect rich Amazonian wetland from overfishing
- Dozens of Indigenous women in Colombia’s Amazon are monitoring, managing, raising awareness and restoring a wetland ecosystem impacted by overfishing.
- After partnering with environmental organizations to establish a fishing agreement in the area, they have witnessed the increase and recovery of fish species such as sardines, catfish and the pirarucu (Arapaima gigas).
- The wetland area of Lake Tarapoto, located in the department of Amazonas in southern Colombia, provides a habitat for numerous aquatic animals and supports the livelihoods of 22 Indigenous communities.
Bringing the ocean’s vast ‘awesomeness’ to light: Q&A with Farah Obaidullah
- “The Ocean and Us,” edited by ocean advocate Farah Obaidullah, provides information from more than 35 female experts on various topics related to the ocean.
- These cover, among others, climate change, overfishing, pollution, ocean management schemes, the human relationship with the ocean, and inclusion and diversity in the ocean space.
- The book helps fulfill the aims of “ocean literacy,” a concept identified by the United Nations as a key driver for achieving the U.N. Decade of Ocean Science for Sustainable Development outcomes.
- “The Ocean and Us” was published by Springer Nature in February 2023.
‘Manta grid’ provides a ray of hope against industrial bycatch threat
- Most species of manta and devil rays (genus Mobula) are endangered, yet industrial purse seine fishing vessels unintentionally catch about 13,000 each year while hunting tuna, according to one scientific estimate.
- New regulations, handling techniques and equipment aim to reduce this number.
- Fishers are working with scientists to return the rays, which are slippery and can weigh as much as a small car, back into the sea when they are brought on deck in fishing nets.
- At the same time, experts warn that far more mobulids die in gillnets set by small-scale and semi-industrial local fishers in countries throughout the tropics.
When a red snapper is more than just a fish: Q&A fisheries scientist Elle Wibisono
- Fisheries scientist and artist Elle Wibisono recently published a children’s book, “A Snapper Tale,” that features red-colored snappers native to Indonesia’s waters.
- Equipped with her extensive knowledge and experience in marine conservation and sustainable fisheries, Wibisono uses her book to highlight the importance of fish identification, a key component of sustainable fisheries.
- Indonesia is home to one of the world’s richest marine ecosystems, with its fisheries sector supplying seafood demand from home and around the world.
- Mongabay’s Basten Gokkon spoke with Elle Wibisono recently about her book and the highlighted fisheries issues, and her hopes for the impacts it will have on readers young and old and on Indonesia’s marine conservation policies.
Fishy business of squid vessels needs stronger regulation, study says
- Experts are drawing attention to the unregulated nature of squid fishing, which they say could lead to the overexploitation of species, allow illegal fishing activity to flourish, and contribute to inequity.
- New research suggests that squid fishing increased by 68% across the global oceans between 2017 and 2020, and that 86% took place in unregulated parts of the ocean.
- China’s distant-water fishing fleet accounts for 92% of this tracked squid fishing activity.
- Experts say that unregulated squid fishing needs to be addressed with better management, monitoring and transparency.
Rule change sees foreign investors back in Indonesia’s fisheries scene
- The Indonesian government on March 6 issued a decree on a fisheries policy change that ushers in quota-based capture in six fishing zones for industrial, local, and non-commercial fishers.
- The policy also allows foreign investment back into the country’s marine capture sector, after it was banned in 2016 in an effort to tackle illegal, unreported and unregulated (IUU) fishing by foreign vessels in Indonesian waters.
- These key changes have raised concerns among some marine conservationists and defenders of artisanal fishers’ rights, who say the new regime is oriented mostly toward the large-scale exploitation of Indonesia’s marine resources when more than half of fishing zones in the country are already “fully exploited.”
- Indonesia is one of the world’s biggest marine capture producers, with some of the richest marine biodiversity on the planet.
As U.N. members clinch historic high seas biodiversity treaty, what’s in it?
- On March 4, U.N. member states reached a landmark agreement on a legally binding treaty aimed at protecting the international waters of Earth’s oceans.
- The deal, more than 15 years in the making, was finalized after talks overran their two-week schedule into a final, grueling 36-hour negotiation marathon.
- Delegates reached consensus on multiple thorny matters, including a framework for establishing and maintaining a network of marine protected areas on the high seas and mechanisms to share benefits from high seas resources fairly among nations.
- For the new high seas treaty to be implemented, delegates must officially adopt the treaty text at an unscheduled next meeting, and then a minimum of 60 states must ratify it, a process that could take months or years.
Will new bottom trawling rules do enough to protect South Pacific seamounts?
- The South Pacific Regional Fisheries Management Organisation (SPRFMO) is an intergovernmental body that regulates fishing across the vast international waters of the South Pacific Ocean.
- At a meeting in Manta, Ecuador, in February, the SPRFMO changed its rules around bottom trawling, a controversial fishing practice that involves dragging fishing gear along the seabed, running roughshod over any organisms or structures in its path.
- The new rules mandate the protection of at least 70% of species that indicate the presence of so-called vulnerable marine ecosystems, such as sponge fields and cold-water coral communities.
- However, conservationists have decried the new rules, calling them less protective than the current policy, let alone the ban on trawling seamounts they’ve been asking for.
Indonesian fisheries fee change promises more revenue, but likely also more violations
- The Indonesian fisheries ministry is implementing a new scheme under which operators of large fishing boats would pay a range of fees after landing their catch instead of before.
- The ministry says the change is meant to boost state revenue from these non-tax fees, but observers warn it opens the potential for an increase in unreported catches.
- That’s because a key feature of the new policy is that it relies heavily on self-declarations by fishing boat operators when reporting the volume of their catch at port.
- Indonesia has one of the biggest fishing industries in the world, employing about 12 million mostly artisanal fishers, and its waters support some of the planet’s highest levels of marine biodiversity.
Fishing industry transparency is key for a thriving ocean (commentary)
- As fish populations decline in many regions, unscrupulous fishing fleet operators have turned to illegal fishing, human trafficking, slavery and other abuses to cut costs.
- This is facilitated by the complex, opaque nature of global fisheries, but there is one essential step every government can and must take to end this and bring fisheries out of the shadows: introducing comprehensive transparency.
- “The fact that illegal fishing, human rights abuses and ecological collapse in the ocean are so closely interlinked means that systematic, rigorous transparency can help to resolve them all,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Herders turn to fishing in the desert amid severe drought, putting pressure on fish population
- As Northern Kenya’s unabating drought continues, a growing wave of pastoralists are finding it challenging to keep their livestock alive and are switching to fishing in Lake Turkana, the world’s largest desert lake.
- However, environmentalists, fishing authorities, and some fishers worry that potential overfishing and increased pressures on fish populations will cause a collapse in fish stocks and the lake’s ecosystem.
- Authorities are also concerned about the rampant use of illegal fishing gear, such as thin mesh nets that catch undersized fish in shallow breeding zones, and an illegal tilapia smuggling network draining the lake by the tons.
- Though no studies have yet been done to assess fish populations, some environmentalists and fishers are calling for better enforcement of regulations to keep livelihoods afloat.
Experts pushing for high-seas fishing ban win ‘Nobel Prize for environment’
- Fisheries experts Daniel Pauly and Rashid Sumaila have won the 2023 Tyler Prize for Environmental Achievement, an award administered by the University of Southern California.
- The prize has been referred to as the “Nobel Prize for the environment” and comes with a $250,000 award to be shared between the two laureates.
- Both Pauly and Sumaila have said they would like to use the prize opportunity to spread the message that it’s necessary to ban all fishing on the high seas, those parts of the ocean that don’t fall under any national jurisdiction.
U.S. grocery chains flunk sustainability, human rights tests for tuna sourcing
- Greenpeace has scored the 16 largest U.S. grocery retailers on human rights and environmental sustainability in their tuna sourcing, giving just one, ALDI, a “passing” overall grade.
- The report gave just two of the retailers, ALDI and Whole Foods Market, passing grades for addressing sustainability issues.
- None of the retailers received a passing grade for efforts to rid their supply chains of forced labor and other human rights abuses.
- The U.S. is the world’s second-largest tuna importer and its retailers wield significant clout within the tuna sector, according to the report.
End of the tuna FAD? Indonesia hopes so, but EU isn’t giving up just yet
- Indonesia has welcomed measures to cut back on the use of fish-aggregating devices, which critics blame for Indian Ocean tuna being caught at unsustainable rates.
- A senior Indonesian fisheries official says all countries on the Indian Ocean coast have a shared interest in tackling the overuse of FADs and in improving the conservation and management of the region’s tuna populations.
- In 2022, the Indian Ocean’s bigeye tuna population was declared overfished, while repeated violation of catch limits for skipjack tuna was reported.
- The European Union, whose fleet accounts for a third of the Indian Ocean tuna catch, has reportedly said it will object to the new resolution; in that event, its vessels will simply continue deploying FADs as usual, since the new measure isn’t enforceable.
Costa Rica announces ban on fishing of hammerhead sharks
- Costa Rica announced an all-out ban on the fishing of hammerhead sharks, specifically the smooth hammerhead (Sphyrna zygaena), scalloped hammerhead (Sphyrna lewini) and great hammerhead (Sphyrna mokarran).
- Despite being critically endangered, hammerhead sharks have been bought and sold in Costa Rica for years, with demand being driven by shark fin soup.
- Although some conservation efforts have been made in the past, the government has been heavily criticized up to now for its relaxed approach to dealing with the overfishing of hammerheads.
Critics allege EU’s ‘toxic collusion’ with fishing lobbies is damaging Indian Ocean tuna
- Members of the Indian Ocean Tuna Commission (IOTC) agreed to reduce the use of drifting fish-aggregating devices (FADs) and to impose three-month closures on the devices, despite opposition from the European Union.
- The EU dominates Indian Ocean tuna fisheries; its fleet of industrial fishing vessels has long reeled in the lion’s share of tuna, including yellowfin, a stock that is now perilously close to collapse.
- Through their sheer numbers and influence in EU delegations, industrial fishing lobbyists have stymied efforts to impose appropriate catch quotas and limit the use of destructive fishing gear like FADs used extensively by EU vessels, an investigation by the French NGO BLOOM Association found.
- In a statement, the European Commission denied the NGO’s allegations that lobbyists shape its positions at IOTC talks, noting that the pandemic led to increased participation from stakeholders and that these stakeholders were observers and not authorized to negotiate on the commission’s behalf.
Study: Paying fishers to ease off sharks and rays is cost-effective conservation
- Paying fishers in Indonesia to not catch sharks and rays could be a cost-effective way of conserving these species, a new study suggests.
- Interviews with fishers at two sites shows that payments of $71,408-$235,927 per year could protect up to 18,500 hammerheads and 2,140 wedgefish at those sites.
- Researchers say this money could come from dive tourism levies, and they are already carrying out a pilot project that has seen fishers release more than 150 hammerheads and wedgefish in eight months.
- An independent expert cautions that there need to be safeguards to prevent a perverse incentive where fishers are deliberately catching these species just so they can release them and claim payment.
Good fisheries management, if enforced, can help sharks and rays recover
- Effective fisheries management, strong regulations, enforcement, and monitoring can help conserve sharks and rays, according to new research.
- Researchers found that some shark populations in the northwest Atlantic recovered after the U.S. implemented a management plan in 1993, despite ongoing fishing, while populations in areas without sufficient management declined.
- A previous study found that overfishing threatens one-third of sharks, rays and chimeras with extinction, making them the second-most endangered vertebrate group, after amphibians.
Mongabay Explains: What’s the difference between artisanal and industrial fishing?
- A new episode of “Mongabay Explains” examines the difference between artisanal and industrial fishing.
- Broadly speaking, artisanal fishing is a form of traditional fishing that uses relatively small, low-powered boats to make short trips close to shore and catch relatively small quantities of fish, whereas industrial fishing uses large vessels that make longer trips farther out to sea and catch larger volumes of fish.
- There are plenty of other differences between the two fishing sectors, too, including their relative impact on the marine environment.
- In this video, Mongabay explores the differences between the two forms of fishing, including some ways people are trying to make each sector more sustainable.
Indigenous Kawésqar take on salmon farms in Chile’s southernmost fjords
- Sixty-seven salmon farms exist within Kawésqar National Reserve in southern Chile, an area that formed part of the Kawésqar Indigenous people’s ancestral lands, and another 66 concessions are under consideration there.
- The salmon industry claims the farms only occupy 0.06% of the reserve, which covers a marine area of 2.6 million hectares (6.4 million acres), and have a legitimate presence in the area.
- But Kawésqar communities accuse the farms of taking up the fjords where their sacred areas and fishing grounds are, of violating their rights on their own territory, and of compromising the ecosystem of the entire reserve through severe pollution.
- Kawésqar communities, with the support of various NGOs, are pursuing numerous legal avenues aimed at excluding salmon farms from the reserve.
Study aims to unmask fishing vessels, and owners, obscured by loopholes
- A new study reveals information about the shifting identities of the global fishing fleet, which can help tackle illegal, unreported and unregulated fishing (IUU) fishing.
- The research combines a decade’s worth of satellite vessel tracking data with identification information from more than 40 public registries to generate a first-of-its-kind global assessment of fishing compliance, foreign ownership of vessels, and reflagging.
- It found that nearly 20% of high seas fishing was likely unregulated or unauthorized, and that the reflagging of vessels, which operators may do to avoid oversight, mainly took place in ports in East Asia, West Africa and Eastern Europe.
- The researchers plan on making a broader data set publicly available soon and regularly updating this data so that authorities have access to timely information.
Mexico dismantles illegal fishing cartels killing off rare vaquita porpoise
- At a press conference, a top navy official confirmed that the Mexican government has arrested members of criminal groups dedicated to illegally fishing totoaba in the Gulf of California.
- Totoaba bladders can go for as much as $80,000 per kilo, earning them the nickname “the cocaine of the sea.”
- Illegal totoaba fishing practices have contributed to the drastic population decline of vaquita, a small porpoise on the brink of extinction.
- Although the government’s arrests could slow the threats against the vaquita, other criminal groups are also interested in trafficking totoaba, suggesting that the fight to conserve marine populations in the gulf isn’t over.
Indonesia’s ‘essential’ mangroves, seagrass and corals remain unprotected
- Much of Indonesia’s mangrove forests, seagrass beds and coral reefs fall outside protected areas, according to a recently published report.
- Indonesia currently has 284,000 square kilometers (110,000 square miles) of marine area under protection, and plans to expand the size of its MPAs to 325,000 km2 (125,000 mi2) by the end of this decade, or 10% of its total territorial waters.
- Less than half of seagrass and coral reefs, and less than a fifth of mangroves, lie within currently protected areas, which experts say could thwart efforts at effective marine conservation.
- The country is home to some of the most diverse marine life on the planet, especially in its eastern region that falls within the Pacific Coral Triangle, an area renowned for its richness of corals and reef fish.
Mongabay Explains: What’s all the brouhaha over bottom trawling?
- A new episode of “Mongabay Explains” examines the controversial fishing method known as bottom trawling, in which vessels drag a net across the seafloor to scoop up bottom-dwelling marine life.
- Ever since the 14th century, fishers who use other gear types — later joined by conservationists and scientists — have objected to bottom trawling, saying the gear takes too many fish and destroys seafloor habitat that’s essential to the functioning of marine ecosystems.
- Proponents of bottom trawling, however, argue that the practice provides an important share of our seafood as well as numerous jobs, and cannot be abandoned.
- In this video, Mongabay takes a look at bottom trawling and the reasons it’s so controversial.
Unsustainable fishing to be banned in Irrawaddy dolphin’s Bornean sanctuary
- Indonesia’s fisheries ministry is working with a conservation NGO to draw up plans prohibiting fishing gear considered dangerous to critically endangered Irrawaddy dolphins in the Mahakam River in Borneo.
- The prohibition will apply to a stretch of the Mahakam that was designated a conservation area earlier this year and that’s home to 90% of the estimated 80 Irrawaddy dolphins in the Mahakam.
- Among the practices they’re seeking to ban are fishing with a type of gill net known as rengge, electrofishing, poison fishing, and fixed-net fishing known as sawaran and kombongan.
- Local fishers are said to be supportive of the plan: “They want to continue fisheries but they also want to get rid of unsustainable fishing … because they care about the dolphins as well.”
Strong marine protected areas credited with manta ray surge in Indonesia
- Manta ray populations are thriving in Indonesia’s Raja Ampat archipelago, a new population assessment shows, highlighting the importance of marine protected areas to the species’ conservation.
- The study showed that reef manta ray (Mobula alfredi) populations saw up to 10.7% compound annual increase from 2009-2019 in the region, even as global ray and shark populations undergo a sweeping decline.
- The study authors attribute this to well-planned and -implemented conservation measures by Indonesian authorities, conservation groups and local communities.
- The finding chimes with the discovery earlier this year that manta ray populations are also flourishing in Komodo National Park, another tightly regulated protected area in Indonesia.
From bombs to seasonal closure, Indonesian fishers move toward sustainability
- Kahu-Kahu village on Sulawesi’s Selayar Island is implementing its first season- and location-based fishery closure.
- The three-month closure of a 6-hectare (15-acre) stretch of coastal water is intended to replenish local octopus populations by reducing fishing pressure.
- Local fishers will install and plant artificial reefs in the area during the closure.
Island shopping: Cambodian officials buy up the Cardamoms’ coast
- A buying spree by Cambodia’s wealthy and politically connected elites has put the fate of a string of small islands in the balance, affecting the livelihoods of local fishers.
- Resort developments threaten the Koh S’dach archipelago’s seagrass and coral ecosystems, which harbor rare and threatened marine life.
- Local fishers have also found themselves locked out of their traditional fishing grounds by the developers, leading to a loss of earnings.
- This story was supported by the Pulitzer Center’s Rainforest Investigations Network where Gerald Flynn is a fellow.
Dalian Ocean Fishing, subject of Mongabay probe, now sanctioned by U.S.
- The U.S. Department of the Treasury’s Office of Foreign Assets Control recently announced sanctions on Chinese individuals and companies allegedly involved in human rights abuses and illegal, unreported, and unregulated (IUU) fishing while operating in distant waters.
- One sanctioned company, Dalian Ocean Fishing Co., Ltd. (DOF), was the subject of two Mongabay investigations: one uncovered widespread human rights abuses, and the other exposed extensive illegal shark-finning operations within the DOF fleet of longline fishing vessels.
- China, which operates the world’s largest distant-water fishing fleet and has a long history of fisheries offenses, denounced the sanctions, saying that it is a “responsible fishing country.”
Tech companies work to make fishing, aquaculture more sustainable
- Several companies around the world are developing technology to make fishing and aquaculture more sustainable.
- These include the use of artificial intelligence to identify non-native species that disrupt marine food webs and the fisheries they support, and lights that attempt to attract only target species to fishing nets in a bid to reduce the capture of non-targeted species.
- With the rapidly increasing global population underscoring the need to source protein more sustainably, experts say it’s urgent to find ways to make fishing less damaging and more productive.
Shark-fishing gear banned across much of Pacific in conservation ‘win’
- The Western and Central Pacific Fisheries Commission has outlawed shark lines and wire leaders, both of which aid industrial-scale fishers in targeting sharks.
- Shark numbers in the open ocean have dropped by roughly 71% in the past 50 years.
- Proponents consider the measure a potentially precedent-setting move that could precede similar bans in other regions.
‘It was a shark operation’: Q&A with Indonesian crew abused on Chinese shark-finning boat
- Rusnata was one of more than 150 Indonesian deckhands repatriated from the various vessels operated by China’s Dalian Ocean Fishing in 2020.
- Previous reporting by Mongabay revealed widespread and systematic abuses suffered by workers across the DOF fleet, culminating in the deaths of at least seven Indonesian crew members.
- In a series of interviews with Mongabay, Rusnata described his own ordeal in detail, including confirming reports that DOF tuna-fishing vessels were deliberately going after sharks and finning the animals.
- He also describes a lack of care for the Indonesian workers by virtually everyone who knew of their plight, from the Indonesian agents who recruited them to port officials in China.
Fishers in Flores Sea opt to limit harvest of overexploited sea cucumbers
- Fishers on Indonesia’s Sapuka island have decided to regulate their sea cucumber harvests.
- Since the 1960s, sea cucumber has been an important commodity for the island, but heavy harvest pressure has pushed the fishery to overexploited status.
- Sea cucumbers play a crucial role in the marine ecosystem by providing food to other species and adding nutrients and pH balance in waters around coral reefs and other shallow-water ecosystems.
As shark numbers plummet, nations seek ban on devastatingly effective gear
- The U.S. and Canada are seeking a ban in the Pacific on two fishing devices, known as wire leaders and shark lines, that have proven devastatingly effective at catching huge numbers of sharks.
- The Western and Central Pacific Fisheries Commission (WCPFC), which governs tuna fisheries in those waters, could vote on the proposal at its annual meeting next week in Vietnam.
- The commission currently allows boats to use either shark lines or wire leaders, but not both simultaneously, but advocates for banning say that’s a loophole taken advantage of by captains and companies that ignore the rules amid scant oversight.
- Banning wire leaders and shark lines would reduce fishing mortality of oceanic whitetip sharks by 40.5% and silky sharks by 30.8%, research has found.
Will shipping noise nudge Africa’s only penguin toward extinction?
- The African penguin (Spheniscus demersus) is expected to go extinct in the wild in just over a decade, largely due to a lack of sardines, their main food.
- A colony in South Africa’s busy Algoa Bay is suffering a population crash that researchers say coincides with the introduction of ship-to-ship refueling services that have made the bay one of the noisiest in the world.
- They say theirs is the first study showing a correlation between underwater noise pollution and a seabird collapse.
- Current studies are investigating whether the ship noise is interfering with the penguins’ foraging behavior and their ability to find fish.
Breeding success raises hopes for future of endangered African penguin
- Two African penguin chicks have hatched at a nature reserve in South Africa where conservationists have been working for years to entice the endangered birds to breed.
- The colony was abandoned more than 10 years ago after a caracal killed a number of penguins.
- The recent hatching comes at a time when survival prospects for Africa’s only resident penguin species look grim, due mainly to declining food stocks.
- But encouraging new colonies at sites close to abundant food sources could help to bring the species back from the brink.
No requiem for sharks just yet as nations push to protect species from trade
- Nations party to CITES, the global convention on the trade in endangered species, are supporting three proposals to list dozens of sharks and rays from three families onto Appendix II of the convention.
- While a CITES Appendix II listing would not prohibit trade outright, it would regulate it by requiring export permits, which would help mitigate overexploitation.
- A recent study found that more than a third of sharks, rays and chimeras are threatened with extinction, making them the second-most threatened vertebrate group, after amphibians.
- The proposals are up for discussion at CITES’s 19th Conference of the Parties, or CoP19, taking place from Nov. 14-25 in Panama.
How Mitsubishi vacuumed up tuna from a rogue Chinese fishing fleet
- Last week, Mongabay revealed a massive illegal shark finning operation across the fleet of a major Chinese tuna fishing firm.
- The company, Dalian Ocean Fishing, mainly serves the Japanese market. Most of its tuna has gone to Japan’s Mitsubishi Corporation and its seafood trading arm, Toyo Reizo.
- While the general outlines of their partnership are well-documented, tracing specific tuna flows from individual fishing boats to Mitsubishi’s supply chain is impeded by the murky nature of the supply chain.
- Experts say this lack of transparency must be solved in order to prevent illegal fishing and labor abuses at sea.
Negotiations to conserve Antarctic Ocean end in stalemate on many issues
- The 41st annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with conserving marine life in the Southern Ocean and managing fisheries there, ended Nov. 4 with little progress made on several key issues.
- In 2009 CCAMLR committed to creating a network of marine protected areas to preserve Antarctic ecosystems. It established one that year and another in 2016, but since then China and Russia have repeatedly blocked the creation of additional protected areas, as well as other conservation-related measures.
- The commission also failed to reach the consensus required to enact new regulations for the krill and toothfish fisheries, or to protect a vast nesting area for icefish discovered earlier this year.
- CCAMLR members did agree to designate eight new vulnerable marine ecosystems, areas home to slow-growing organisms such as corals, sponges, brittle stars and feather stars that are now permanently protected from bottom fishing.
Did climate change really kill billions of snow crabs in Alaska?
- In October 2022, the National Oceanic and Atmospheric Administration (NOAA) announced that the lucrative snow crab fishery in the Bering Sea would close for the first time, following a population decline of 80% between 2018 and 2022.
- While fisheries managers and biologists say climate change is to blame for the species’ retreat, some fishers and crab experts suggest that trawling bycatch and other fishing activity may have played a role in the snow crab’s decline.
- The fishery’s closure has amplified a chorus of concerns about Alaska’s trawling industry and the knowledge gaps around its potential impact on fisheries.
Small island, big ocean: Niue makes its entire EEZ a marine park
- In April, Niue, a small island nation in the South Pacific Ocean, designated its entire exclusive economic zone — an area about the size of Vietnam — as a multiple-use marine park called Niue Nukutuluea.
- Forty percent of the park is a no-take marine protected area; a smaller slice is managed by local villages. And about 56% of the park is a general-use zone where commercial fishing and other activities, including possibly deep-sea mining, could take place.
- The country has developed an unusual mechanism to fund the park, and is gathering support to confront the perennial challenge of monitoring and compliance in technologically advanced ways.
‘There are solutions to these abuses’: Q&A with Steve Trent on how China can rein in illegal fishing
- Earlier this week, Mongabay published an article uncovering a massive illegal shark finning scheme across the fleet of one of China’s largest tuna companies, Dalian Ocean Fishing.
- China has the world’s biggest fishing fleet, but oversight of the sector is lax, with many countries’ boats routinely found to be engaging in illegal and destructive practices, especially in international waters.
- Mongabay spoke with Steve Trent, the head of the Environmental Justice Foundation, which has also investigated the fishing industry, about DOF’s shark finning scheme and how China can better monitor its vessels.
Fish eggs return to Bangladesh’s Halda River following conservation efforts
- The Halda River, considered the world’s only natural gene bank for several pure Indian carp species, as well as home to dozens of endangered Ganges River dolphins, has made a comeback after fish eggs all but disappeared from the river several years ago.
- Historical records say around 4,000 kilograms (8,818 pounds) of fish eggs could be found in the river in 1941, but that number nearly hit zero in 2016 due to overexploitation and industrial pollution.
- Since 2018, the Bangladesh government has made robust conservation efforts, including steps to declare the river an Ecologically Critical Area and fish heritage site.
- In 2020, about 424 kgs (935 lbs) of fish eggs were found in the river; however, yields have since fallen after an unexpected tropical cyclone, Amphan, triggered salinity intrusion and there was low rainfall during the monsoons.
