Plan aims to allow tuna population to recover from overfishing, but conservationists say endangered mako shark has been overlooked

Conservationists welcomed “long overdue” catch limits set this week for bigeye tuna and other Atlantic species, but criticised weak measures to rebuild endangered mako shark populations.

The International Commission for the Conservations of Atlantic Tunas (ICCAT) – responsible for the management of tuna and tuna-like species and bycatch including sharks and rays – set new catch limits for bigeye tuna at a meeting in Palma, Mallorca, this week. It also agreed to reduce juvenile fish mortality by limiting certain fishing practices.

Study finds seal and sea otter populations in Alaska hit by killer infection that migrated from North Atlantic

A potentially deadly disease affecting marine mammals, including seals and sea otters, has been passed from the North Atlantic Ocean to the northern Pacific thanks to the melting of the Arctic sea ice.

Experts have long been concerned that sea ice melting in the northern oceans, caused by global climate heating, could allow previously geographically limited diseases to be transmitted between the two oceans.

The vanishing: Ghana’s defenders face new perils in fight against overfishing

Posted on by

Illegal fishing by Chinese-owned trawlers is costing the country millions – and one of the officials trying to stop it has now been missing for months

In his cramped living room in an Accra backstreet, Bernard Essien pulls out a sheet of paper – a statement signed by his elder brother Emmanuel and addressed to the Ghanaian police. Two weeks before 28-year-old Emmanuel vanished at sea, his handwritten account and accompanying video footage alleged illegal fishing by a trawler he had been working on. If the allegation was proved true, the ship’s captain faced a minimum fine of $1m.

Emmanuel Essien was a fishing observer, one of Ghana’s frontline defenders against an overfishing crisis that is among the worst in west Africa. Illegal and destructive practices by foreign-owned trawlers are draining the Ghanaian economy of an estimated £50m a year. Along its 350-mile coastline, overfishing has driven small pelagic species known as “people’s fish”, the staple diet, to the verge of collapse.

Poorly planned Amazon dam project ‘poses serious threat to life’

Posted on by

Operator faces choice of weakening 14km barrier or potentially devastating a biodiversity hotspot

The biggest hydroelectric project in the Amazon rainforest has a design flaw that poses a “very serious” threat to human life and globally important ecosystems, according to documents and expert testimony received by the Guardian.

The studies suggest engineers failed to anticipate the impact of water shortages on the Pimental dam at Belo Monte, which has been closed and turned into a barrier. This is forcing the operators to choose between a structural weakening of the 14km-wide compacted-earth barrier and a reallocation of water in the reservoir or on the Xingu river, which is home to indigenous communities, fishing villages and some of the world’s most endangered species.

Cook Islands: manager of world’s biggest marine park says she lost job for backing sea mining moratorium

Posted on by

Environmentalist Jacqueline Evans says she was dismissed from the Marae Moana for urging caution on deep-sea mining

The public champion of the world’s largest marine reserve – the Cook Islands’ Marae Moana – has said she lost her job managing it because she supported a moratorium on seabed mining in the Pacific.

Six months ago, Jacqueline Evans won the Goldman Environmental prize – the world’s foremost environmental award – for her work establishing Marae Moana (meaning “sacred ocean”), which covers the Cook Islands’ entire exclusive economic zone of more than 1.9m sq km.

High levels of mercury and banned industrial fluids, found in blubber and skin, can impact reproduction

Bottlenose dolphins in the Channel have been found to carry a “toxic cocktail” of chemicals in their bodies, some of which have been banned for decades and which may be harming the marine mammals’ health, scientists have said.

Belgian and French scientists said they detected high accumulations of industrial fluids and mercury in the blubber and skin of dolphins in the waters off the north-west coast of France.

Plastic pollution has entered the fossil record, research shows

Plastic pollution is being deposited into the fossil record, research has found, with contamination increasing exponentially since 1945.

Scientists suggest the plastic layers could be used to mark the start of the Anthropocene, the proposed geological epoch in which human activities have come to dominate the planet. They say after the bronze and iron ages, the current period may become known as the plastic age.

Victory for community concerned about the industry’s environmental costs strengthens calls for shakeup of rules along Chilean coast

A growing wave of resistance to the expansion of salmon farms along the Chilean coast has led to an important victory in the fight to protect a pristine fjord in southern Patagonia, home to indigenous groups and an array of stunning wildlife.

Dolphins, whales and colonies of penguins thrive in the 240km-long Beagle Channel, an area of outstanding natural beauty between Chile and Argentina which attracts tourists from all over the world.

Reforms will oblige Cuba to work more closely with its US neighbours – in spite of US President Trump’s frosty attitude

Cuba has introduced sweeping reforms of its fishing laws in a move seen as smoothing the way for possible collaboration with the US on protecting their shared ocean, despite Donald Trump’s policy of reversing a thaw in relations.

The move is the first time the text of an environmental law in Cuba specifies the need for scientific research, which experts say will mean greater reliance on state-of-the-art US technology.

Vets say plastic caused orphan mammal’s infection and should serve as warning about pollution

An orphaned dugong named Marium, who became an internet star after being rescued in Thailand in April, has died.

Veterinarians caring for the dugong off the island of Koh Libong, in south Thailand’s Trang province, said an infection caused by ingesting plastic contributed to her death. They added that the loss of the animal, named “the nation’s sweetheart” by Thailand’s department of marine and coastal resources (DMCR), should serve as a warning about the effects of plastic waste on wildlife.

Temperatures lead to what appears to be largest local die-off in 15 years, raising fears for broader ecosystem

In all her years working at Bodega Bay, the marine reserve research coordinator Jackie Sones had never seen anything like it: scores of dead mussels on the rocks, their shells gaping and scorched, their meats thoroughly cooked.

A record-breaking June heatwave apparently caused the largest die-off of mussels in at least 15 years at Bodega Head, a small headland on the northern California bay. And Sones received reports from other researchers of similar mass mussel deaths at various beaches across roughly 140 miles of coastline.
