Prize-winning author Richard Flanagan slams the Tasmanian salmon industry, describing it as disastrous for the environment, with overstated health benefits — and alleging the public had not been told the extent of the expansion plans for fish farms around the state.

While humans domesticate plants and animals, these relationships are surprisingly rare in other species. Our new study found a species of fish that appears to have domesticated a kind of tiny shrimp.

Every fall, coho salmon undertake an epic journey from the ocean back to the freshwater streams and creeks where they were born so they can reproduce and then die shortly after. For several decades, though, scientists have observed that a disturbing number of these migrating fish in the Pacific Northwest die while swimming through urban waterways polluted by stormwater runoff. At some sites, between 40 and 90 percent of returning salmon may die before they have a chance to spawn.

When you think about fish, it's probably at dinnertime. Author Jonathan Balcombe, on the other hand, spends a lot of time pondering the emotional lives of fish. Balcombe, who serves as the director of animal sentience for the Humane Society Institute for Science and Policy, tells Fresh Air's Terry Gross that humans are closer to understanding fish than ever before.

How many people want dolphins killed? Apart from the psychopath shooting them in Florida, and the Japanese hunters slaughtering them every year in Taiji cove, I would hazard a guess at none. They are perhaps the world’s most loved wild animals. Yet, every day, dolphin killers form an orderly queue, at supermarket checkouts in the UK and around the world. If you are buying fish, and there is no clear and watertight guarantee, you are likely to be complicit in something that would revolt you.

Forget dreams of wolves, bears or lynx – the next animal to be restored to the British countryside could be a river bottom-dwelling fish that resembles a giant tadpole.

Newly-obtained footage shows the underwater fish farm pipe in British Columbia is still churning out virus-infected blood and guts.

The star of Pixar's blockbuster "Finding Nemo" may be about to vanish again - this time for good - as its peculiar mating habits put it at risk from climate change, scientists said on Tuesday.

The use of nanoparticles in consumer products like textiles, foods and personal care products is increasing. What is so special about nanoparticles is their tiny size: One nanometer is one-billionth of a meter.

A newly discovered species of electric eel can produce an 860-volt electric shock.

Scientists believe heat stress killed thousands of salmon in an Alaskan river last month. From July 7 to 11, communities along the Koyukuk River experienced sustained air temperatures of over 30 C, well above the seasonal average highs of less than 20 C. Shortly after the heat wave, locals began reporting an unusual number of dead chum salmon washing up on the banks of the river.

While SCUBA diving off the coast of Zanzibar, marine biologist Luiz Rocha saw a fish he had never seen before. He sent a photograph to his collaborator Yi-Kai Tea, currently a Ph.D. candidate at the University of Sydney, who confirmed that it was a new species of fairy wrasse from the genus Cirrhilabrus. As a fan of the Marvel cinematic universe who had just helped to discover a bright purple fish in an isolated environment in Africa, Tea knew there was just one name they could give their discovery: Cirrhilabrus wakanda, the Vibranium fairy wrasse.
