Ancient giant river dolphin species found in the Peruvian Amazon
- Paleontologists discovered a fossilized skull of a newly described species of giant freshwater dolphin in the Peruvian Amazon, which lived around 16 million years ago and is considered the largest-known river dolphin ever found.
- The ancient creature, measuring 3-3.5 meters (9.8-11.5 feet), was surprisingly related to South Asian river dolphins rather than the local, living Amazon river pink dolphin and shared highly developed facial crests used for echolocation.
- The discovery comes at a time when the six existing species of modern river dolphins face unprecedented threats, with their combined populations decreasing by 73% since the 1980s due to unsustainable fishing practices, climate change, pollution, illegal mining and infrastructure development.
- Conservation efforts are underway, including the signing of the Global Declaration for River Dolphins by nine countries and successful initiatives in China and Indonesia, highlighting the importance of protecting these critical species that serve as indicators of river ecosystem health.

Irrawaddy dolphin death in Thailand’s Songkhla Lake underscores conservation needs
- As few as 14 critically endangered Irrawaddy dolphins remain in the world’s smallest freshwater population of the species, in southern Thailand’s Songkhla Lake.
- The recent death of one of the remaining few raised the alarm among cetacean specialists, who say more must be done to save the imperiled population.
- Teetering on the brink of extinction, the dolphins face a slew of threats from entanglement in fishing nets, depletion of fish populations, and deteriorating lake conditions due to increasing pressures from agriculture, industry and infrastructure development.
- Experts say a “once-in-a-lifetime” opportunity to reverse the dolphin’s trajectory of decline is on the horizon in the form of major funding for dolphin conservation linked to a road bridge megaproject, but they warn it will only be successful if government agencies can put aside their competing agendas.

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.

AI unlocks secrets of Amazon river dolphins’ behavior, no tagging required
- Freshwater dolphins in the Amazon Basin navigate through flooded forests during the wet season using their flexible bodies and echolocation clicks.
- Researchers have combined advanced acoustic monitoring and AI to study the habits of endangered pink river dolphins (boto) and tucuxi in seasonally flooded habitats.
- They used hydrophones to record sounds in various habitats and employed convolutional neural networks (CNN) to classify the sounds as either echolocation clicks, boat engine noises, or rain — with high accuracy.
- Understanding the dolphins’ movements and behaviors can aid conservation efforts to protect these endangered species, as they face various threats such as fishing entanglement, dam construction, mining, agriculture and cattle ranching.

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.

Fishing, dams and dredging close in on Peru’s river dolphins, study shows
- Amazon river dolphins in Peru are facing increasing threats from human activity, including fishing, proposed construction of dams, and dredging operations
- A study tracked the movements of dolphins in relation to fishing areas, dams and dredging sites, and found that 89% of their home range is subject to fishing activity.
- The research team observed that the dolphins in the study were, on average, located roughly 252 kilometers (157 miles) from the nearest proposed dam and 125 km (78 mi) from the closest proposed dredging site.
- The construction of the Amazon Waterway, aimed at improving navigability along waterways in Peru, involves dredging sites across four main rivers in the basin and could lead to ship collisions with dolphins, increased underwater noise, and habitat degradation.

‘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.

Banned but abundant, gillnets pose main threat to Bangladesh’s river dolphins
- Bangladesh is home to around 2,000 Ganga River dolphins and 6,000 Irrawaddy dolphins, found mostly in the Sundarbans, the world’s largest mangrove forest.
- Both species, considered threatened on the IUCN Red List, run a high risk of entanglement in the gillnets used by local fishers.
- Gillnets are banned in Bangladesh, but remain popular among local fishers, with the government unable to crack down on their use.
- To conserve the freshwater dolphins, the government has embarked on a 10-year action plan that includes declaring more areas as dolphin sanctuaries and raising awareness among fishers.

Greenland shark, world’s longest-living vertebrate, gets long-awaited protection
- In September, the Northwest Atlantic Fisheries Organization (NAFO), an intergovernmental organization that manages fisheries, prohibited the retention of Greenland sharks in international waters.
- This ban would apply to the intentional catching of Greenland sharks as well as the retention of the species as bycatch.
- However, bycatch exceptions could be made if countries prohibit the discarding of fish.
- Greenland sharks are known to be the longest-living vertebrate in the world, reaching ages of between 270 and 500 years.

Death of last river dolphin in Laos rings alarm bells for Mekong population
- Earlier this year, the last Irrawaddy river dolphin in a transboundary pool between Cambodia and Laos became entangled in fishing gear and died, signifying the extinction of the species in Laos.
- The transboundary subpopulation had dwindled from 17 individuals in 1993, with experts blaming a range of factors — from the use of gill nets and other illegal fishing practices, to overfishing, genetic isolation, and the effects of upstream dams on river flow and prey availability.
- With the loss, there are now just an estimated 89 Irrawaddy dolphins left in the Mekong River, all within a 180-km (110-mi) stretch in Cambodia, where they face the same range of threats that wiped out the transboundary group.
- Authorities and conservationists say they are now resolved to strengthen protections and improve public awareness of the dolphins’ vulnerability to ensure the species has a future in the Mekong.

Pingers on fishing nets found to save river dolphins in Indonesian Borneo
- A trial has demonstrated that underwater acoustic pingers can keep river dolphins at a safe distance from fishing nets, preventing fatal entanglements.
- Fishers in the Mahakam River in Indonesian Borneo collaborated with researchers to test the devices that emit a high-frequency sound that acts as a deterrent to the local population of freshwater Irrawaddy dolphins.
- Aside from protecting the dolphins, the devices were also found to increase fishers’ catches and reduce costly repairs to nets; experts describe this as a “win-win” solution.
- International river dolphin initiatives are now testing the devices in locations such as the Amazon, the Ganges and the Indus rivers to find out if they can be implemented at a much larger scale to safeguard dwindling river dolphin species worldwide.

In Gabon, a new partnership protects sharks and rays
- The diversity of habitat in Gabon’s waters creates a perfect home for a wide range of shark and ray species: from whale sharks to giant manta rays, scalloped hammerheads, and guitarfish.
- A partnership between the government and conservation NGO Wildlife Conservation Society highlights a new global initiative to save the world’s sharks and rays, launched this World Ocean Day.
- The first new law fully regulates shark and ray catches and special authorization will now be needed to target sharks and rays, and a second adds a wide range of sharks and rays to Gabon’s list of fully protected marine species.
- This article is an analysis. The views expressed are those of the authors, not necessarily Mongabay.

Small steps aim to make a large ocean safer for rays
- New rules that apply to a vast swath of the Pacific Ocean aim to improve manta and devil rays’ chances of surviving encounters with tuna fishing boats.
- The measure prohibits fishers from targeting the rays or keeping the ones they catch accidentally. It also mandates that fishers release rays that survive being caught in a manner “that will result in the least possible harm.”
- Growth in demand for manta and devil ray gill plates and anecdotal reports of decreasing populations have raised concerns about the effects of overfishing, both intentional and accidental.

New nets make shrimp trawling more sustainable in Latin America and Caribbean
- When fishers accidentally catch non-target species, they either sell the so-called bycatch or throw it back into the ocean, almost always dead.
- Newly invented nets have allowed shrimp trawlers to reduce bycatch by 20 percent.
- Globally, almost 10 million tons of potentially usable fish are thrown back into the ocean every year.

AI and public data identify fishing behavior to protect hungry seabirds
- In an effort to reduce albatross deaths as bycatch of longline fishing, Global Fishing Watch (GFW) and Birdlife International researchers are using machine learning models to determine if fishing vessels are setting their lines at night, a recommended technique to avoid accidentally killing albatrosses.
- Mapping fishing vessel behavior involved training new models to recognize when a long-line ship is setting its line.
- This new application broadens the range of GFW’s toolkit to combine machine learning and public data to protect marine wildlife and better manage fisheries.
- Results of the new algorithm formed the basis of a January 2019 regulatory decision by the South Pacific Regional Management Organization.

Why are more female than male Magellanic penguins stranded in South America every year?
- Thousands of Magellanic penguins become stranded every year along the coast of South America, from northern Argentina all the way down to southern Brazil, and are unable to make it back to their breeding grounds in Patagonia 1,000 miles or more away.
- Scientists have observed that the penguins that get left behind are three times as likely to be female as male. But, due to a dearth of data on the penguins’ migratory habits, it could not be determined why there was such a gender-based discrepancy to the strandings.
- New research published this month in the journal Current Biology sheds new light on the situation, however, finding that, among other behavioral differences, female Magellanic penguins are likely to venture farther north than their male counterparts — and that by doing so, they’re more likely to run into the kinds of trouble that can leave them stranded.

‘Biological passports’ show whale sharks travel less than we thought
- A study looking at chemical signatures in whale shark tissue and using photographic identification has revealed that young sharks in three countries along the western rim of the Indian Ocean don’t typically stray more than a few hundred kilometers from their feeding sites.
- Of the more than 1,200 sharks photographed, only two traveled between different feeding sites — in this case, about 2,000 kilometers (1,240 miles) between Mozambique and Tanzania.
- The authors of the study say their findings demonstrate that local conservation of these populations is important because if whale sharks are wiped out in an area, they’re unlikely to repopulate it later on.

And then there were 12: Why don’t we hear about extinction until it’s too late? (commentary)
- Species threatened with extinction often don’t get the public’s attention until they no longer exist.
- The author, zoologist Sam Turvey, argues that more attention to these critical cases is required.
- Ahead of International Save the Vaquita Day on July 7, Turvey points out that the world’s most endangered marine mammal is dangerously close to extinction, and it’s not alone.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Hunting, fishing causing dramatic decline in Amazon river dolphins
- Both species of Amazon river dolphin appear to be in deep decline, according to a recent study. Boto (Inia geoffrensis) populations fell by 94 percent and Tucuxi (Sotalia fluviatilis) numbers fell by 97 percent in the Mamirauá Reserve in Amazonas state, Brazil between 1994 and 2017, according to researchers.
- Difficult to detect in the Amazon’s murky waters, both species are listed as “Data Deficient” by the IUCN. But researchers maintain that if region-wide surveys were conducted both species would end up being listed as Critically Endangered.
- The team noticed scars from harpoon and machete injuries on the dolphins they caught. Interviews with fishermen confirmed the team’s suspicions: dolphins were being hunted for use as bait. The mammals also get entangled in nets and other fishing gear, are hunted as food, eliminated as pests, and suffer mercury poisoning.
- Researchers believe the passage and enforcement of new conservation laws could save Amazon river dolphins, and halt their plunge toward extinction. But a lack of political will, drastic draconian cuts to the Brazilian environmental ministry budget, and continued illegal dolphin hunting and fishing make action unlikely for now.

Fishing gear poses the greatest danger to young great whites off the West Coast of the U.S.
- Fishing lines and nets pose the most significant threat to the survival of young white sharks in the waters off Mexico and southern California, according to a new study.
- A team of scientists used a relatively “untapped” but ubiquitous storehouse of data to develop a statistical model for the survival rates of juvenile white sharks.
- The researchers calculated that 63 percent of young white sharks living in this part of the Pacific survive annually, but that nearly half probably come in contact with gillnets set by commercial fishers.
- The findings point to best practices, such as barring gillnets from inshore “nurseries” and asking fishers to check their nets for trapped sharks more regularly, that could help protect great whites.

More than 800 totoaba swim bladders confiscated by Mexican authorities in smuggling busts
- In two separate arrests of Chinese nationals, Mexican police confiscated more than 800 swim bladders from a large fish called the totoaba.
- Totoaba swim bladders are used in traditional medicine and can fetch thousands of dollars per kilogram in Chinese markets.
- Fishing for totoaba has also pushed a small porpoise called the vaquita close to extinction. One recent estimate puts the number of animals left in the wild at 12.

NOAA publishes global list of fisheries and their risks to marine mammals
- The list, published in draft form in late 2017 as part of requirements laid out by the Marine Mammal Protection Act, includes nearly 4,000 fisheries across some 135 countries.
- NOAA says the list represents ‘a strong step forward’ in developing sustainable fisheries.
- These fisheries have until 2022 to demonstrate that the methods they use to catch fish and other marine animals either pose little risk to marine mammals or employ comparable methods to similar operations in the United States.

Vaquita survival hinges on stopping international swim bladder trade
- Recent investigations by the Elephant Action League and WWF have uncovered the complicated trade in fish swim bladders from the Gulf of California that is pushing a porpoise known as the vaquita toward extinction.
- A two-year-old gillnet ban so far has not yet stemmed the declining numbers of vaquita, which are down 50 percent since 2015 and 90 percent since 2011.
- Not more than 30 vaquita remain in the wild, making it the most endangered cetacean on the planet.
- The swim bladders can sell for as much as $20,000 per kilogram.

Namibia’s low cost, sustainable solution to seabird bycatch
- Accidental take of marine animals by commercial fisheries is a serious global environmental problem, with 40 percent of the world’s ocean fishing totals disposed of as bycatch annually.
- Roughly 63 billion pounds of unwanted wildlife — seabirds, marine mammals and sea turtles, countless fish species, rays, and cephalopods — are killed as bycatch due to the swallowing of baited hooks or entanglement in nets.
- Namibia, once known as the “world’s worst fishery” regarding avian bycatch is addressing the problem. It has installed “bird-scaring” lines on the nation’s 70 trawlers and on its 12 longline fishing vessels, and has also adopted other low cost methods to minimize avian bycatch, which once killed more than 30,000 birds annually.
- The Meme Itumbapo Women’s Group, known for its seashell necklaces and other jewelry, is now sustainably manufacturing and supplying the bird-scaring lines from their headquarters “Bird’s Paradise,” in Walvis Bay, Namibia. The hope is that these combined efforts will reduce avian bycatch by 85-90 percent in the near future.

Fishing nets kill ‘high proportion’ of adult loggerhead turtles in the Mediterranean
- Researchers tracked 27 female loggerhead turtles using satellite devices over a ten-year period from 2001 to 2012.
- The year-long survey revealed, for the first time, that the turtles were using multiple nesting sites hundreds of kilometres apart, researchers say.
- Three of the 27 turtles died within the first year of being followed due to entanglement in fishing nets, suggesting an annual mortality rate of 11 percent, which the team says is “alarmingly high”.

Peru to protect world’s largest-known population of giant Manta Rays
- On December 31, 2015, Peru’s Ministry of Production passed a resolution banning fishing of manta rays, according to a release by WildAid, a nonprofit organization.
- The regulation also mandates, among other requirements, that all mantas caught as bycatch be immediately released back into the ocean.
- The new regulation, however, does not protect mobula rays that belong to the same taxonomic family as the manta rays.

Almost half of U.S. seafood goes to waste
- A new study calculated the amount of seafood wasted at every step of the U.S. supply chain, from fishing vessel to table, between 2009 and 2013.
- Of the country’s total annual supply of 4.7 billion pounds of seafood, the study found that roughly 2.3 billion pounds — or about 44 percent — went to waste each year.
- That’s enough seafood to satisfy the annual protein needs of about 10 million men or 12 million women, according to the paper, or to fill the annual caloric needs of 1.5 million adults, according to the study.

Dolphins caught in fishing nets: to eat or not to eat?
- Small-scale fishermen and women in West African fishing communities commonly treat accidentally caught dolphins as an opportunistic source of food, according to a recent study
- Cultural differences often govern consumption patterns of dolphin meat, the study found.
- Protecting dolphins in the region would require protection of fish stocks in the West African waters and prevention of overfishing by industrial fishing vessels from developed countries, researchers said.

Collateral damage: new findings shed light on the full impact of commercial fishing

Aside from reducing the populations of the species sought for capture, commercial fisheries are also killing thousands of non-target creatures such as sharks, albatross, and sea turtles, collectively referred to as “bycatch.” However, the full extent of the problem is only beginning to be grasped. In an attempt to fill the many knowledge gaps when […]
Nearly half a million seabirds die in gillnets every year, but solutions exist

A recent study from the Biological Conservation journal brings shocking news: every year across the globe, an estimated 400,000 seabirds are killed by gillnets. Gillnets, a common term for any net used to entangle and catch fish, are used all over the world, and at any depth. These nets, whether used in subsistence or commercial […]
Ultraviolet nets significantly reduce sea turtle bycatch

Bycatch, a side-effect of commercial fishing in which non-target species are accidentally caught, is linked to severe population declines in several species. Sea turtles are particularly impacted by small-scale coastal gillnetting practices, in which large nets are deployed and indiscriminately snag anything of a certain size that attempts to swim through them. However, that may […]
