Some of the world’s largest, oldest fish live in Oregon. Why anyone would want to vandalize them, even abduct them, takes explaining. By Adrian Shirk.

Yoshitaka Takahashi’s hands are shaking as he scores and cleans the skin of the fish in front of him. The tension rises again when his knife reaches the liver. The slightest mistake in removing the highly toxic organ could end in an agonising death for anyone who eats his fish. Twenty minutes later, the chef has successfully prepared a whole fugu – or puffer fish – a Japanese delicacy whose capacity to maim and kill is dividing the country’s culinary world.

Up to 900 reef sharks survive in one of the most untouched reef environments in the world, researchers have found.

Charles Foster, author of “Being a Beast: Adventures Across the Species Divide,” proposes that humans spend less time thinking about or even observing animals and more time emulating them. To appreciate what it’s like to be an otter, try catching fish in your mouth. To appreciate what it’s like to be a fox, try sleeping under a porch by day and foraging through garbage bins at night. The conceit is obviously demented, and Foster, a man of—by his own description—“shaggy, anarchic pretensions,” pursues it with unhinged élan. By Elizabeth Kolbert.

It is widely understood that hunting wild fish is not sustainable. Fish farming, or aquaculture, is being promoted by some as a sustainable replacement to catching wild fish. And a new generation of fish farming approaches promise to address many of its past controversies. The portion of global fish stocks that are classed as overfished has risen from about 10% in 1974 to over 30% today. Other estimates place the number of fish stocks overexploited at as high as 85%.

Many have tried to keep a white shark in captivity. Here's why that's so difficult.

Researchers in Hawaii have discovered three probable new species of fish while on an expedition in the protected waters of the Papahanaumokuakea Marine National Monument.

A new study indicates that fish personalities can be influenced and changed by social context — meaning fish may be more complex and socially aware than we previously believed. Fish, in general, have long had a reputation as one of the least independently-minded groups of animals on the planet. The image of a school of fish flowing together almost as one larger creature can seem to solidify the idea that the fish themselves are interchangeable automatons and indistinguishable from each other in every way.

A new fish counting method has revealed there are ten times more fish in the sea than we previously thought.

Coalition government announces budget funds for national plan to control Australia’s worst freshwater feral pest

A massive fish kill was reported last week in the Queule River Estuary in Chile, leaving over 1,000 tons of dead sardines covering the waters and beaches and creating a human health threat. It is ironic that this story should come out just one day after Digital Journal reported on the closing of sardine fishing this year on the Pacific Coast of the U.S. because mention was made of the fluctuation in sardine populations.

In some areas, bluefin tuna is harvested at triple sustainable levels

Ladies, did you know your birth control pills might be having a terrible effect on frogs and other amphibians? By Susan Bird.

Just hold on, buddy. We're gonna get you out of there.

Migrating creatures produce a low, distinct hum

A new study on steelhead trout in Oregon offers genetic evidence that wild and hatchery fish are different at the DNA level, and that they can become different with surprising speed. The research, published today in Nature Communications, found that after one generation of hatchery culture, the offspring of wild fish and first-generation hatchery fish differed in the activity of more than 700 genes. A single generation of...

The United States has given Pacific Island nations notice that it plans to withdraw from the South Pacific Tuna Treaty, one of its most important aid, trade and geopolitical arrangements with the region.
