‘Aphrodisiac’ of the ocean: how sea cucumbers became gold for organised crime

Posted on by

Overfishing and smuggling of this crucial animal are affecting biodiversity and the livelihood of local fishers in Sri Lanka

It’s after sunset in Jaffna when Anthony Vigrado dives into the waters of Palk Bay, scanning the seafloor to collect what seems to be prized treasure. What he comes back with are sea cucumbers – long, leathery-skinned creatures that are increasingly valuable and the source of his income for the past 12 years.

But after a 10-hour search, his harvest is only a fraction of what it used to be, as the shores of northern Sri Lanka and southern India have become a prime spot for exploitation.

Marine scientists ‘alarmed’ after four gray whales found dead in San Francisco Bay

Posted on by

Deaths discovered over a course of nine days are ‘just the tip of the iceberg’ for the species, says expert

Four dead gray whales have washed ashore on San Francisco Bay Area beaches in the last nine days, with experts saying on Friday one had been struck by a ship. They were trying to determine how the other three had died.

“It’s alarming to respond to four dead gray whales in just over a week because it really puts into perspective the current challenges faced by this species,” says Dr Padraig Duignan, the director of pathology at the Marine Mammal Center.

The rice of the sea: how a tiny grain could change the way humanity eats

Posted on by

Ángel León made his name serving innovative seafood. But then he discovered something in the seagrass that could transform our understanding of the sea itself – as a vast garden

Growing up in southern Spain, Ángel León paid little attention to the meadows of seagrass that fringed the turquoise waters near his home, their slender blades grazing him as he swam in the Bay of Cádiz.

It was only decades later – as he was fast becoming known as one of the country’s most innovative chefs – that he noticed something he had missed in previous encounters with Zostera marina: a clutch of tiny green grains clinging to the base of the eelgrass.

If you like salmon, don’t read this: the art duo exposing a booming £1bn market

Posted on by

Farmed salmon can end up deformed, blind, riddled with sea lice and driven to eat each other. Eco art activists Cooking Sections are highlighting their plight – and getting Tate to change its menus

A few months back, a book arrived in the post – tiny, not much larger than a bank card. Though the cover was grey, its pages were a riot of pinks, from deepest persimmon to pale rose. Printed on them were dense, technical essays referencing everything from fish farming to Adam Smith’s The Wealth of Nations. The title was Salmon: A Red Herring.

Fish is an unexpected topic for an art book – but then the duo who created this little volume, Daniel Fernández Pascual and Alon Schwabe, aren’t really going for the coffee-table market. Operating under the name Cooking Sections, the pair have a thing for food. Their art is about what we eat and its impact on the Earth.

  • Scientists caution high death rate is outpacing births
  • Population of whales estimated at around 360

North Atlantic right whales gave birth over the winter in greater numbers than scientists have seen since 2015, an encouraging sign for researchers who became alarmed three years ago when the critically endangered species produced no known offspring at all.

Canada’s herring facing ‘biological decimation’, say First Nations and activists

Herring off western coast will ‘teeter on edge of complete collapse’ if commercial fishing continues at current level, says report

First Nations and conservationists are warning that Pacific herring populations are “collapsing” off Canada’s western coast, and are appealing for a moratorium on commercial fishing until the critical species can rebuild.

Emmie Page, a marine campaigner with the organization Pacific Wild, said in the past, five large commercial herring fisheries opened each year on the coast.

The waste caught by fishing boats used to be thrown back into the sea but in Kerala it is now turned into black gold

For years, plastic caught by fishing communities on the Kollam coast in India’s southern state of Kerala was thrown back into the water, damaging aquatic ecosystems and killing fish.

But fishers are spearheading an innovative initiative to clean up the ocean – along with their daily hauls of fish, they pull in and collect the waste that gets enmeshed in their nets.

Seaspiracy: Netflix documentary accused of misrepresentation by participants

Posted on by

NGOs and experts quoted in film say it contains ‘misleading’ claims, erroneous statistics and out-of-context interviews

A Netflix documentary about the impact of commercial fishing has attracted celebrity endorsements and plaudits from fans with its damning picture of the harm the industry does to ocean life. But NGOs, sustainability labels and experts quoted in Seaspiracy have accused the film-makers of making “misleading claims”, using out-of-context interviews and erroneous statistics.

Seaspiracy, made by the team behind the award-winning 2014 film Cowspiracy, which was backed by Leonardo DiCaprio, pours doubt on the idea of sustainable fishing, shines a spotlight on the aquaculture industry and introduces the notion of “blood shrimp”, seafood tainted with slave labour and human rights abuses.

The beluga whale who became famous: Aleksander Nordahl’s best photograph

Posted on by

‘He was called Hvaldimir and he would play in front of crowds at Hammerfest harbour in Norway. One woman dropped her phone and he fetched it for her’

In April 2019, a beluga whale appeared alongside fishing boats off the coast of Norway. He was wearing a harness. A fisherman called Joar Hesten freed him, and saw the harness had stamped on it “equipment of St Petersburg”. The media went crazy, with talk of a “spy whale”, and the creature was named Hvaldimir, a combination of hval, the Norwegian word for whale, and Vladimir, a nod to Russia’s President Putin.

The whale became famous. There were Instagram videos of him playing in Hammerfest harbour in front of crowds. One woman dropped her phone in the water and the whale fetched it for her. He would bring up bones from the depths to show people, almost like little gifts. It became this huge moment on social media: everyone in the country fell in love with the whale. Even the hardcore fishing villages melted for Hvaldimir.

As tourism plummets and fishing nets go empty, more are attempting the treacherous 1,000 mile journey to the Canaries

In the old Senegalese port city of Saint Louis, 12 women step off the sun-baked street and through a doorway draped with pink silk into a dim room beyond.

After greetings are over, one by one they recount their stories. Recent memories of husbands, sons and brothers they have lost at sea, revealing precious pictures on smartphones of moments when they last cradled children or kissed their families.

Sperm whales in 19th century shared ship attack information

Whalers’ logbooks show rapid drop in strike rate in north Pacific due to changes in cetacean behaviour

A remarkable new study on how whales behaved when attacked by humans in the 19th century has implications for the way they react to changes wreaked by humans in the 21st century.

The paper, published by the Royal Society on Wednesday, is authored by Hal Whitehead and Luke Rendell, pre-eminent scientists working with cetaceans, and Tim D Smith, a data scientist, and their research addresses an age-old question: if whales are so smart, why did they hang around to be killed? The answer? They didn’t.

Revealed: seafood fraud happening on a vast global scale

Posted on by

Guardian analysis of 44 studies finds nearly 40% of 9,000 products from restaurants, markets and fishmongers were mislabelled

A Guardian Seascape analysis of 44 recent studies of more than 9,000 seafood samples from restaurants, fishmongers and supermarkets in more than 30 countries found that 36% were mislabelled, exposing seafood fraud on a vast global scale.

Many of the studies used relatively new DNA analysis techniques. In one comparison of sales of fish labelled “snapper” by fishmongers, supermarkets and restaurants in Canada, the US, the UK, Singapore, Australia and New Zealand, researchers found mislabelling in about 40% of fish tested. The UK and Canada had the highest rates of mislabelling in that study, at 55%, followed by the US at 38%.

Retailers join calls for ‘urgent’ action to restrict harmful tuna fishing methods

‘Fish aggregating devices’ have been linked to depletion of yellowfin populations and increased bycatch in the Indian Ocean

Global condemnation is growing at the increasingly widespread use of harmful “fish aggregating devices” (FADs) in the fishing industry, as retailers including Sainsbury’s, Marks & Spencer and the German chain Edeka joined calls for restrictions.

A letter signed by more than 100 NGOs, retailers and artisanal fisheries urges this week’s meeting of the Indian Ocean Tuna Commission (IOTC) to consider proposals by Kenya and Sri Lanka to monitor, manage and restrict FADs. The signatories warn of an “urgent need” to improve management of FADs in order to reduce overfishing and rebuild populations of yellowfin tuna.

Keep your head: the self-decapitating sea slugs that regrow their bodies – hearts and all

The disembodied head of the sacoglossan sea slug feasts on algae while its old body decomposes, and a new one grows

If you can keep your head when all about you are losing theirs, then it’s unlikely that you are a sacoglossan sea slug (apologies to Rudyard Kipling).

Scientists in Japan have discovered that this species of sea slug can decapitate itself and then regrow an entirely new body, complete with a beating heart and other vital organs.

Jasmine Harrison, the youngest woman to make the 3,000-mile journey alone, relished the freedom of doing it all by herself

It was always during the night when things went wrong for Jasmine Harrison, the youngest woman to row solo across the Atlantic Ocean. Like the time her boat hurtled into a huge wave at 19.2 knots and capsized, leaving her with a badly injured elbow.

“I was basically thrown at a wall at 20-odd miles an hour. That’s going to hurt, especially in the middle of your sleep,” she said. “Everything happened when I was asleep.”

Volunteers gather to remove clumps of tar in cleanup effort that could take months or years, officials say

Israeli authorities are trying to find the ship responsible for an oil spill that drenched much of its Mediterranean shoreline with tar, an environmental blow that will take months or years to clean up, officials said.

Thousands of volunteers gathered on Sunday to remove clumps of sticky black refuse from the pale beaches. Israel’s military said it was deploying thousands of soldiers to help with the effort. Authorities warned members of the public to keep their distance until further notice.

Curiosity and sociability among traits found, despite dolphins having evolved separately for millions of years

Dolphins have developed a number of similar personality traits to humans, despite having evolved in vastly different environments, researchers have found.

A study, published in the Journal of Comparative Psychology, looked at 134 male and female bottlenose dolphins from eight facilities across the world, with each dolphin’s personality being assessed by staff at the facilities. The results of the study found a convergence of certain personality traits, especially curiosity and sociability.

Scientists surprised by marine organisms on boulder on sea floor beneath 900 metres of ice shelf

The accidental discovery of marine organisms on a boulder on the sea floor beneath 900 metres (3,000ft) of Antarctic ice shelf has led scientists to rethink the limits of life on Earth.

Researchers stumbled on the life-bearing rock after sinking a borehole through nearly a kilometre of the Filchner-Ronne ice shelf on the south-eastern Weddell Sea to obtain a sediment core from the seabed.
