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.

In a Noah’s Ark move, PNG migrants bring thousands of trees to safer ground
- Facing sea level rise and food insecurity, 17 families from the Carteret Islands have relocated to nearby Bougainville, bringing hundreds of specimens of trees and plants, representing dozens of species, across a small stretch of ocean.
- They’ve planted more than 175,000 plants, breathing life into a forest on new lands donated by the Catholic Church.
- This “green migration” is helping them preserve their lifestyle and identity, sources say, echoing the journey of early Polynesian settlers who carried “canoe plants” as they sailed and settled across the Pacific.
- Scientists say green migrations could become part of climate relocation planning, but there also needs to be careful consideration of whether species can be moved and become unsustainably invasive.

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

Largest dam removal ever, driven by Tribes, kicks off Klamath River recovery
- The largest dam-removal project in history was completed in October, freeing 676 kilometers (420 miles) of the Klamath River and its tributaries in California and Oregon.
- The project involved removing four dams, built between 1918 and 1964 to provide electricity. They had devastating effects on salmon populations and tribal communities, leading to a decades-long, tribe-led movement for their removal.
- The $450 million project involved complex engineering to remove the dams and, now, to restore the river ecosystem, including replanting native vegetation and reshaping the river channel, incorporating tribal knowledge to improve habitats for salmon and other species.
- The first chinook salmon in more than 60 years are already spawning above the former Iron Gate dam and a fall-run Chinook salmon was identified in Oregon for the first time in more than 100 years. Experts expect coho salmon populations to recover in six to 12 years and Chinook salmon in 15 to 20 years in what was once the third-largest salmon producing river in the contiguous U.S.

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

Not merely ‘exploration’: PNG deep-sea mining riles critics & surprises officials
- Deep Sea Mining Finance (DSMF), an obscure company registered in the British Virgin Islands, recently conducted an exploratory mining operation off the coast of New Ireland province in Papua New Guinea (PNG), according to civil society members and a government official’s statements to the media.
- Satellite-based vessel-tracking data show that much of this mining activity took place in and around a controversial project site known as Solwara 1, where mineral-rich hydrothermal vents are located.
- Critics say the operation was illegal and that DSMF’s activities flout two ongoing moratoria that should prevent deep-sea mining in PNG’s territorial waters. On the other hand, a national official has said the company operated within its rights to explore the deep sea for minerals.
- The operation appears to have caught many by surprise, including government authorities meant to oversee such activities.

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.

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

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

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.

It will take 880 years to achieve UN ocean conservation goals, at this rate (commentary)
- Indigenous conservationist Angelo Villagomez will speak at the Our Ocean conference, one of the largest and highest profile conferences of its kind, this week in Athens, Greece.
- He plans to say that ocean conservation has lost momentum toward protecting 30% of the ocean by 2030 and that a lot more needs to be done to address the human dimensions of conservation, including guaranteeing access rights, equity, and justice.
- “At this rate, raising the area of global ocean protection from 8% to 30% will take an additional 880 years,” he argues in a new op-ed.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Communities worry anew as PNG revives seabed mining plans
- Coastal communities in Papua New Guinea’s New Ireland province rely on the sea for their livelihoods and culture.
- But Solwara 1, a resurgent deep-sea mining project aimed at sourcing metals from the ocean floor, could threaten their way of life, community leaders and activists say.
- They also say they haven’t been properly consulted about the potential pros and cons of Solwara 1, and government and company leaders have provided little information to the public about their plans.
- A coalition of leaders, activists and faith-based organizations called the Alliance of Solwara Warriors is opposing the project in Papua New Guinea and abroad, and calling for a permanent ban on seabed mining in the country’s waters.

‘Corals dying’ as yet more bleaching hits heat-stressed Great Barrier Reef
- Both aerial and in-water surveys have shown that the southern section of the Great Barrier Reef is undergoing extensive coral bleaching.
- Surveys have also shown “limited bleaching” in the northern part of the Great Barrier Reef.
- However, scientists and reef managers plan to conduct more air and in-water surveys to further assess the coral bleaching across all parts of the Great Barrier Reef.
- Scientists suspect but have not yet confirmed that a seventh mass bleaching event since 1998 is currently underway; the last mass bleaching event on the Great Barrier Reef happened in 2022.

PNG communities resist seabed mining: Interview with activist Jonathan Mesulam
- The government of Papua New Guinea appears poised to approve Solwara 1, a long-in-development deep-sea mining project in the country’s waters.
- However, PNG has signed onto several seabed mining moratoria, and scientists have urged caution until more research can determine what the effects of this practice will be.
- Proponents say the seafloor holds a wealth of minerals needed for batteries, especially for electric vehicles, and thus are vital for the transition away from fossil fuels.
- But coastal communities in PNG’s New Ireland province have mounted a fierce resistance to Solwara 1, arguing that it could damage or destroy the ecosystems that provide them with food and are the foundation of their cultures.

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.

Salmon and other migratory fish play crucial role in delivering nutrients
- Pacific salmon can play a key role in transporting nutrients from marine to freshwater and terrestrial ecosystems.
- In the past, Pacific salmon and other anadromous fish that spawn in freshwater and spend part of their life in the ocean likely played a much larger role in global nutrient cycles, scientists find.
- But today, many populations of Pacific salmon and other anadromous fish are under pressure from habitat loss, overfishing, climate change, dams and other pressures that have greatly reduced their numbers, weight and ability to migrate freely.
- Population declines could further curtail their role in global nutrient transport in future, with increasing consequences, especially for nutrient-poor ecosystems that have relied in the past on migratory fish for significant nutrient additions.

Photos: Top species discoveries from 2023
- Scientists described a slew of new species this past year, including an electric blue tarantula, two pygmy squid, a silent frog, and some thumb-sized chameleons.
- Experts estimate less than 20% of Earth’s species have been documented by Western science.
- Although a species may be new to science, it may already be well known to local and Indigenous people and have a common name.
- Many new species of plants, fungi, and animals are assessed as Vulnerable or Critically Endangered with extinction as soon as they are found, and many species may go extinct before they are named, experts say.

Marine conservation technology hub rises from old L.A. wharf (analysis)
- In 2014, the Port of Los Angeles gave a 50-year lease to an aging wharf called City Dock No. 1 to a project called AltaSea.
- AltaSea is a non-profit project founded in 2014 that in less than 10 years has become a leading ‘blue economy’ research hub focused on renewable ocean energy, sustainable aquaculture and other blue technologies.
- Hub tenants include marine renewable energy startups, sustainable aquaculture projects, a marine seed bank, a research effort aimed at decarbonizing oceanic shipping, and other projects.
- This article is an analysis. The views expressed are those of the author, not necessarily of Mongabay.

Lethal or not? Australia’s beaches are a crucible for shark control methods
- For decades, Australia’s east-coast states have attempted to keep beachgoers safe from sharks by deploying entangling shark nets and culling species deemed dangerous.
- Recent figures published by the state of New South Wales reveal that almost all the animals caught in the nets during the 2022/23 summer season were “nontarget” species, including turtles, dolphins and endangered shark species, the majority of which died due to entanglement in the nets.
- In contrast, the west-coast state of Western Australia has abandoned a shark culling regime in favor of nonlethal alternatives, such as drone monitoring and “eco barriers,” swimming enclosures that keep marine life out but do not risk entanglement.
- Despite calls from environmental groups to exclusively adopt nonlethal technologies, shark control programs are continuing in both New South Wales and its northern neighbor, Queensland, during the 2023/24 Australian summer.

Galápagos waters yield massive deepwater corals in latest biodiversity find
- Researchers have found two new deepwater coral reefs, including one that spans more than 800 meters, or half a mile long, in the waters around the Galápagos Islands.
- They were discovered through the process of mapping the seafloor in Galápagos Marine Reserve with laser scanning technology.
- The reefs displayed a diversity of stony coral species and other organisms such as crustaceans, sharks and skates.
- The discovery of these two reefs occurred six months after the first discovery of deepwater reefs in the waters of the Galápagos Islands.

Pacific alliance adopts moratorium on deep-sea mining, halting resurgent PNG project
- The Melanesian Spearhead Group put in place a moratorium on deep-sea mining within its member countries’ territorial water in a declaration signed Aug. 24.
- Leaders from Fiji, Papua New Guinea, the Solomon Islands, Vanuatu and an alliance of pro-independence political parties known as FLNKS from the French territory of New Caledonia said more research is needed to establish whether mining the seabed below 200 meters (660 feet) is possible without damaging ecosystems and fisheries.
- The moratorium ostensibly thwarts the return of Nautilus Minerals, a Canadian company, to Papua New Guinea and its Solwara 1 project in the Bismarck Sea, where it had hoped to mine gold and copper from sulfide deposits on the seafloor.
- Proponents of deep-sea mining say that minerals found deep beneath the ocean are necessary for the production of batteries used in electric vehicles and thus are critical in the global transition away from fossil fuels.

Hope, but no free pass, as Pacific corals show tolerance to warming oceans
- New research suggests that coral reefs in the Pacific islands of Palau are becoming increasingly tolerant to thermal stress brought on by climate change.
- The study found that Palau’s coral reefs appeared to suffer less bleaching over three successive marine heat waves in 1998, 2010 and 2017.
- While the findings provide some hope for coral reefs, one expert says the study has some limitations in providing a clear picture of how corals respond to different heat events.
- Scientists also say that reducing carbon emissions is essential to safeguard coral reefs — and to secure the planet’s future.

Deep-sea mining project in PNG resurfaces despite community opposition
- An embattled deep-sea mining project appears to be moving ahead in Papua New Guinea, according to officials in the Pacific Island nation, despite more than a decade of opposition from local communities on the grounds that it could harm the fisheries on which they rely as well as the broader ecosystem.
- Backers of deep-sea mining say it could help provide the gold, copper and other minerals necessary for the transition to electric vehicles and away from fossil fuels.
- But deep-sea mining has not yet happened anywhere in the world, and scientists, human rights groups and Indigenous communities highlight the lack of evidence demonstrating its safety.
- The Alliance of Solwara Warriors is a group of Indigenous communities and church organizations that have been fighting the Solwara 1 project in Papua New Guinea, which received the world’s first deep-sea mining license from PNG in 2011.

To protect the oceans, we must map them (commentary)
- About 80% of our oceans remain “unmapped, unobserved, and unexplored,” according to NOAA.
- Technologies like un-crewed marine drones, high-resolution satellites, and remote operating vehicles are now being paired with modern digital mapping techniques to reveal critical new insights about the oceans.
- “Considering we’ve barely mapped a quarter of [the oceans] so far, imagine what we could know, what we could prepare for, if every inch was mapped,” a new op-ed suggests.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Expedition to Pacific ecosystems hopes to learn from their resilience
- An expedition led by National Geographic’s Pristine Seas project will voyage across the Pacific over five years to gather information about marine ecosystems needing protection.
- The Pristine Seas team will collaborate with Pacific island nation governments, communities, Indigenous and local peoples, and local scientists, to gather data and produce films.
- The first stop of the expedition will be the southern Line Islands, part of Kiribati, to understand how its reefs recovered after an El Niño triggered a large-scale bleaching event in 2015 and 2016.

Australia bushfires may have caused global climate phenomenon La Niña: Study
- The 2019-2020 Australian bushfires threw up so much ash into the atmosphere that it resulted in a cooling of the southern Pacific and hence a La Niña climate phenomenon, a new study says.
- Volcanic eruptions that send vast ash plumes into the atmosphere are thought to trigger La Niña events, but this is the first time a fire has been recorded as doing so.
- La Niña can produce ruinous weather conditions in contrasting ways, from additional hurricanes in North America and droughts in the Horn of Africa, to crop failures in South America.
- The study’s findings call into question the assumption in current climate models that biomass emissions — including from bushfires — will decrease over time.

Hawaiian communities restore Indigenous conservation, from mountains to sea
- In Hawai’i, an Indigenous stewardship and conservation system known as ahupua’a is slowly being revived on a mountain-to-sea scale in partnership with U.S. government agencies.
- Three Indigenous communities that have successfully reintroduced the ahupua’a system are seeing some conservation successes, such as a 310% increase in the biomass of surgeonfish and an increase in the Bluespine unicornfish (Naso unicornis) population.
- The inclusion of Indigenous Hawaiian conservation, social and spiritual values, like Aloha kekahi i kekahi, have been key to building these conservation areas and forming better working relations with the government.

How do you study one of the world’s rarest whales?
- Researcher Dana Wright is one of a handful of scientists studying one of the world’s rarest creatures, the North Pacific right whale.
- With about 500 individuals remaining, and its eastern population that swims off the coast of North America totaling perhaps 30 individuals, it’s so rare that in a decade of research, she has yet to see a living individual of the population, though her colleagues have.
- How does one study a creature that’s so hard to document? With tools like bioacoustics, for example, and Wright has listened to tens of thousands of hours of recordings to aid the conservation of these endangered animals.
- The team continues to develop new approaches to solving the mystery of these whales’ migratory patterns and biology with a goal of identifying — and then protecting — the location of their winter calving grounds.

In Chile’s Patagonia, another salmon plant angers water defenders
- The Dumestre salmon plant near the Chilean city of Puerto Natales is receiving backlash from conservationists who say the facility will dump waste into Patagonian waters.
- The plant can process over 70,000 tons of fish per year, requiring the management of 23,000 cubic meters of industrial liquid waste and the movement of 350 ships in the Señoret canal.
- Local activists say the community wasn’t properly consulted about their needs before the plant was opened.

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.

Machine learning makes long-term, expansive reef monitoring possible
- Conservationists can now monitor climate impacts to expansive marine ecosystems over extended periods of time, a task that used to be impossible, using a tool developed by scientists in the U.S.
- The machine learning tool, called Delta Maps, provides a new way to assess which reefs might be best suited for survival, and which play a key role in delivering larvae to others, and therefore should be targeted for preservation efforts, according to the scientists.
- The scientists used the tool to examine the impacts of climate change on connectivity and biodiversity in the Pacific Ocean’s Coral Triangle, the planet’s most diverse and biologically complex marine ecosystem.
- The authors also noted that the Coral Triangle had more opportunities for rebuilding biodiversity, thanks to the region’s dynamic climate component, than anywhere else on the planet.

‘They’re everywhere out there’: Three new nautilus species described
- Researchers have described three new species of nautilus found in the Coral Sea and the South Pacific.
- The three species can be differentiated due to genetic structure, shell size and coloration, and geographic location.
- Scientists generally know very little about nautiluses but are working to fill in the data gaps to understand how to protect them.
- Nautiluses are highly threatened by the shell trade, as well as pollution and the impacts of climate change.

Potential impact on whales overlooked as deep-sea mining looks set to start, experts say
- Scientists say future deep-sea mining activities could impact cetaceans through noise pollution, which could interfere with their communication processes.
- According to an opinion piece, a team of experts say assessments of deep-sea mining impact have focused on species associated with the seabed rather than transitory megafauna that inhabit the proposed mining areas, and that urgent research is needed to understand the potential impact on cetaceans.
- However, a mining company says it is evaluating the potential impact of its proposed operations on cetaceans through the gathering of acoustic data during its recent mining test in the CCZ, which it will combine with three years of environmental baseline data.
- Deep-sea mining in international waters may begin later this year after the Pacific island nation of Nauru, which sponsors a subsidiary of a Canadian mining firm, requested accelerated approval of its mining operation.

More than half of reef sharks and rays threatened with extinction, study shows
- More than half of known species of coral reef sharks and rays are already threatened with extinction, mostly because of overfishing, according to new research.
- The researchers reported that population trends were declining for 94 coral reef shark and ray species; of the two groups, rays were more threatened than sharks.
- Reef sharks and rays are typically caught for human consumption, and to a lesser extent for use in apparel or accessories, in aquarium displays, as food for domestic animals, and in traditional medicine.
- The study calls for urgent urgent measures to improve regional fisheries and marine protected areas management.

Deliberate dumping of plastic trash in the Pacific: How widespread is it? (commentary)
- In late August of 2022, the sea turtle conservation team of Osa Conservation in Costa Rica noticed a significant increase in plastic debris, mostly drink bottles, arriving on the beaches they patrol.
- An analysis revealed the region of their manufacture to mostly be East Asia, and the manner of their arrival suggested that this was a deliberate dumping of the plastic waste near Costa Rica, not from somewhere across the Pacific.
- This kind of illegal dumping activity has been documented elsewhere: “We need to find better ways to enforce internationally agreed laws such as MARPOL Annex V, which bans the dumping of plastics at sea,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Top 15 species discoveries from 2022 (Photos)
- A resplendent rainbow fish, a frog that looks like chocolate, a Thai tarantula, an anemone that rides on a back of a hermit crab, and the world’s largest waterlily are among the new species named by science in 2022.
- Scientists estimate that only 10% of all the species on the planet have been described. Even among the most well-known group of animals, mammals, scientists think we have only found 80% of species.
- Unfortunately, many new species of plants, fungi, and animals are assessed as Vulnerable or Critically Endangered with extinction.
- Although a species may be new to science, it may already be well known to locals and have a common name. For instance, Indigenous people often know about species long before they are “discovered” by Western Science.

Extinct sea cow’s underwater engineering legacy lives on today, study finds
- In a new study, scientists said that the extinct Steller’s sea cow impacted kelp forests in the North Pacific by browsing at the surface, which would have encouraged the growth and strengthening of the algal understory.
- Not only would sea cows have positively impacted kelp forests in the past, but they may have also enhanced their resilience into modern times, according to the authors.
- Globally, kelp forests face many threats, including ocean warming, which can lead to an overabundance of predatory urchins.
- The authors suggest that it might be possible for humans to reproduce the species’ impact on the canopy of kelp forests to enhance kelp forest resilience.

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.

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.

A new tool to peer into fishing networks: Q&A with Austin Brush of C4ADS
- Washington, D.C.-based think tank C4ADS is launching Triton, a web tool to visually display the corporate structures behind fishing vessels.
- The initial cache of data focuses on the industrial fishing fleets of five key flag states: China, Taiwan, South Korea, Spain, and Japan, which together account for most high-seas fishing.
- Understanding who owns these vessels ultimately reveals the factors driving a vessel’s movements at sea and fishing activity, according to C4ADS analyst Austin Brush.

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.

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.

Exclusive: Shark finning rampant across Chinese tuna firm’s fleet
- Dalian Ocean Fishing used banned gear to deliberately catch and illegally cut the fins off of huge numbers of sharks in international waters, Mongabay has found.
- Just five of the company’s longline boats harvested roughly 5.1 metric tons of dried shark fin in the western Pacific Ocean in 2019. That equates to a larger estimated shark catch than what China reported for the nation’s entire longline fleet in the same time and place.
- The findings are based on dozens of interviews with men who worked throughout the company’s fleet of some 35 longline boats. A previous investigation by Mongabay and its partners uncovered widespread abuse of crew across the same firm’s vessels.
- Campaigners said Dalian Ocean Fishing’s newly uncovered practices were a “disaster” for shark conservation efforts.

New Zealand convicts company of illegal trawling in high seas restricted area
- In late August, a court in Aotearoa New Zealand convicted a subsidiary of one of the country’s major seafood companies of illegal trawling in a closed area in the Tasman Sea between New Zealand and Australia.
- The judge fined the company NZ$59,000 (about $33,000) and the skipper NZ$12,000 (about $7,000), and seized the vessel.
- It’s the fourth case in the past five years where courts convicted New Zealand-flagged vessels of illegal trawling.
- The recent conviction comes amid an ongoing debate about trawling in New Zealand, with campaigners calling for a ban on bottom trawling on submarine mountains, and the industry disputing their arguments and resisting aspects of the proposed change.

Arctic sea ice loss to increase strong El Niño events linked to extreme weather: Study
- The frequency of strong El Niño events could increase by 35% by the end of the century as Arctic sea ice begins to melt out completely in the summer, according to a recent modeling study. El Niños — buildups of especially warm water in the eastern Pacific off of Peru — often trigger ‘devastating’ droughts, floods and cyclones around the globe.
- The findings provide more evidence that Arctic warming is affecting weather in other parts of the world — not only in the mid-latitudes, but as far away as the tropics.
- Other recent studies have found that sea ice loss is causing rapid acidification of the Arctic Ocean and more extreme precipitation and flooding in Svalbard, a Norwegian archipelago located between mainland Norway and the North Pole.

Plastic impacts a grossly underestimated ‘one-two punch’ for seabirds: Study
- That plastic pollution is harmful to marine life, including seabirds, is well known, but recent research finds that the impacts may be “grossly underestimated” and that plastics can affect multiple organs.
- A new study investigated plastic ingestion by flesh-footed shearwaters and found that — as was determined in past research — initial consumption can harm the stomach. New evidence also showed that impacts are far more expansive, and may cause ongoing health problems distributed throughout body organs.
- Some forms of tissue damage detected by the new research suggest that plastic particles may also act as chemical pollutants, though this requires further study.
- Plastic pollution is a massive growing problem for the world’s oceans and marine life. Earlier this year, researchers announced that the global planetary boundary for novel entities — including plastics — has been surpassed, threatening Earth’s operating systems and life as we know it.

Regulator approves first deep-sea mining test, surprising observers
- The International Seabed Authority (ISA), the intergovernmental body responsible for overseeing deep-sea mining operations and for protecting the ocean, recently granted approval for a mining trial to commence in the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean.
- The company undertaking this trial is Nauru Ocean Resources Inc (NORI), a subsidiary of Canadian-owned The Metals Company (TMC), which is aiming to start annually extracting 1.3 million metric tons of polymetallic nodules from the CCZ as early as 2024.
- The approval for this mining test, the first of its kind since the 1970s, was first announced by TMC earlier this week.
- Mining opponents said the ruling took them by surprise and they feared it would pave the way for exploitation to begin in the near future, despite growing concerns about the safety and necessity of deep-sea mining.

In Japanese waters, a newly described anemone lives on the back of a hermit crab
- A newly described anemone species has been found off the coast of Japan and appears to live exclusively on the shells of one hermit crab species.
- First-of-its-kind video recordings of the hermit crab and anemone duo show the hermit crab moving to a new shell and spending more than 40 hours poking, peeling and dragging the anemone to come along.
- Researchers believe the hermit crab and anemone are in an obligate symbiotic relationship, or that they need each other to survive.
- The anemone eats falling debris and protects the hermit crab from parasites and predators, and in turn, gets to hitch a ride to fresh feeding grounds.

‘We’ve got to help the oceans to help us’: Q&A with deep-sea explorer Dawn Wright
- On July 12, oceanographer and geographer Dawn Wright descended 10,919 meters (35,823 feet) below the surface of the ocean to the deepest known part of the planet, Challenger Deep, alongside deep-sea explorer Victor Vescovo.
- Wright was the first Black person to make the voyage to Challenger Deep, where she and Vescovo documented several findings, including the discovery of a beer bottle on the seabed.
- The goal of the expedition was to test out a side-scan sonar designed to go down to 11,000 m (nearly 36,100 ft) that can take detailed images of the seafloor, which was successfully achieved.
- Mongabay’s Elizabeth Claire Alberts spoke to Wright before and after her expedition to learn more about the voyage’s personal significance to Wright, the challenges in venturing this far down into the ocean, and the significance of understanding more about the deep-sea.

Study: Climate impacts to disproportionately hurt tropical fishers, farmers
- The majority of 72 coastal communities studied in five countries in the Indo-Pacific region may face significant losses of agricultural and fisheries products — two key food sources — simultaneously under the worst-case climate change projections, a new study shows.
- These potential losses may be coupled with other drivers of change, such as overfishing or soil erosion, which have already caused declining productivity, the study adds.
- But if carbon emissions can be effectively managed to a minimum, the study’s authors say, fewer communities would experience losses in both the agriculture and fisheries sectors, indicating the importance of climate mitigation measures.
- The current global average temperature is 1.1°C (2°F) above pre-industrial times, and climate experts have warned that it could climb to about 3°C (5.4°F) higher by the end of this century if nothing changes.

Young Māori divers hunt invasive crown-of-thorns starfish to save coral reefs
- The island of Rarotonga in the Cook Islands is experiencing an outbreak of crown-of-thorns-starfish (taramea, Acanthaster planci), which could jeopardize the survival of its surrounding coral reef.
- Local environmental organization Kōrero O Te `Ōrau has been tackling the outbreak since 2020 by training young Māori people in scuba diving and running regular expeditions to remove taramea from the reef and bury them inland.
- The work has contained the outbreak on two sides of the island by collecting over 3,700 crown-of-thorns starfish, ultimately mitigating its impact on reef health. However, ongoing efforts are required.
- The project is also upskilling young Cook Islanders in marine management theory and practice.

Nickel, Tesla and two decades of environmental activism: Q&A with leader Raphaël Mapou
- Nickel mining in New Caledonia, a French overseas territory in the south Pacific, is receiving international attention after the electrical vehicle giant Tesla recently invested in its largest mine, Goro.
- The mine has been plagued by environmental and social issues for the last decade. It is related to five chemical spills and Indigenous Kanak struggles for sovereignty over its resources.
- Raphaël Mapou is a Kanak leader who established the environmental organization Rhéébù Nùù in 2002 as a means to address concerns about the effects of mining at Goro.
- In an interview with Mongabay, Mapou talks about the legacy of Rhéébù Nùù and if a change of ownership at Goro, combined with Tesla’s investment, can deliver positive outcomes for surrounding communities.

All eyes on Tesla as it invests in a troubled nickel mine
- American manufacturing giant Tesla invested in New Caledonia’s Goro mine in 2021, raising local expectations that international scrutiny and the mine’s new owners could help the plant overcome past environmental mismanagement issues and social woes.
- Since 2010, there have been five recorded acid leaks at the Goro mine into nearby bays and reefs. The mine is also related to Indigenous Kanak struggles for sovereignty over its resources and violent protests in 2020.
- The mine was bought by Prony Resources, whose shares are largely owned by New Caledonian stakeholders, including local communities. Kanaks now see themselves as stakeholders and watchdogs in the mine’s production.
- Local organizations and researchers plan to keep a close eye on the environmental impacts of mining in New Caledonia, especially as Prony Resources proposes a new waste management process and China lays out its interests in the region.

Scaling Palauan tradition to regional fisheries: Q&A with Noah Idechong
- After training as a traditional hunter and fisherman in his village in Palau as a boy, Noah Idechong has since become a “bit of a legend” in Pacific marine conservation.
- He has been a government official, an activist, a politician, a legislator, and the founder of a domestic conservation NGO. Currently, he’s the executive director for Micronesia and Polynesia at the international conservation NGO The Nature Conservancy.
- In all of these roles, Idechong has focused on one main thing: championing the traditional systems the communities of Palau employ to protect and conserve the archipelago’s rich marine biodiversity and domestic fisheries.
- Today, he’s applying that ethos at a regional scale as he helps build more sustainable regional tuna fisheries that benefit the Pacific island nations in whose waters the tuna swim, rather than foreign fishing enterprises.

Oceans conference comes up with $16b in pledges to safeguard marine health
- The seventh Our Ocean Conference took place in the Pacific island nation of Palau on April 13 and 14.
- Representatives of governments, the private sector, civil society groups and philanthropic organizations made 410 commitments worth more than $16 billion toward improving the health, productivity and protection of the world’s oceans.
- Discussions focused around the importance of ocean-based climate solutions and the linkage between healthy oceans and healthy communities.
- The setting in a small island developing state lent the event a unique perspective, underscoring the crucial role and leadership of Indigenous peoples and local communities in tacking the climate change and ocean crises.

‘A huge mistake’: Concerns rise as deep-sea mining negotiations progress
- The International Seabed Authority (ISA), the U.N.-affiliated organization tasked with managing deep-sea mining activities, recently held a series of meetings to continue negotiating the development of mining regulations.
- Deep-sea mining may start as early as 2023 after Nauru triggered a two-year rule embedded in the U.N. Convention on the Law of the Sea that could essentially allow its sponsored company to start mining with whatever regulations are currently in place.
- Many states are eager to finalize a set of regulations over the next 15 months that would determine how mining can proceed in the deep sea.
- But other states and delegates have noted the lack of scientific knowledge around deep-sea mining, the absence of a financial compensation plan in the event of environmental damage, and ongoing transparency issues in the ISA — and the unlikelihood of finalizing regulatory measures in a short period of time.

Ships sunk in nuclear tests host diverse corals, study says. But do we need them?
- Researchers surveyed 29 warships at Bikini Atoll and Chuuk Lagoon and found that they hosted up to a third of coral genera found on natural reefs in neighboring regions.
- This study has led researchers to ask a controversial question: Can these kinds of shipwrecks act as biodiversity havens for corals?
- While the study does not provide an answer to this question, the authors say this idea should be explored.
- Climate change is one of the biggest threats to coral reefs since rising temperatures can cause widespread bleaching events.

Geneticists have identified new groups of tiger sharks to protect
- New genetic studies revealed at least two distinct groups of tiger sharks in the Atlantic and Indo-Pacific ocean basins, plus a third smaller population near Hawaii.
- These results are a mild surprise, due to the versatility and long swimming ranges of tiger sharks.
- Fisheries managers should take precautions to protect these distinct genetic populations, researchers urge.
