It really should be consumed at least twice a week.
A study of middle-aged British women shows that omega-3 has beneficial effects on gut health.
The offspring of mice who don't get enough DHA during pregnancy are more likely to have pups that display schizophrenia-like symptoms.
Snapper is one of the fish under New Zealand’s Quota Management system.
New Zealand’s fisheries are considered among the best managed in the world, but this perception doesn't match the facts.
Plastic trash on San Francisco’s Ocean Beach.
A new study shows that anchovies – key food for larger fish – are attracted to plastic trash because it smells like food. This suggests that toxic substances in plastic could move up through food chains.
Tiny hairs cover the bodies of honeybees — including this one dusted in pollen — that allow them to detect molecular “fingerprints” similar to how home security sensors work.
Bees and home security cameras use the same complex techniques to monitor their environments.
A beached hoodwinker sunfish, the new species described by researchers from Murdoch University.
A four-year puzzle has ended with the discovery of a new species of sunfish. These famously strange-looking animals are the largest bony fish in the oceans.
A shark’s nose is chemosensory only, and it doesn’t join up to the back of the throat like ours does.
Sharks can't sneeze like we do, but they can do other cool tricks -- like making their stomach stick out of their mouth to get rid of unwanted stuff.
A tank can give a good idea of what will happen out in the wild.
A new study suggests the benefits of a boost to marine plant growth from increased carbon dioxide will be cancelled out by the increased stress to fish species.
Fish leave bits of DNA behind that researchers can collect.

Animals shed bits of DNA as they go about their lives. A new study of the Hudson River estuary tracked spring migration of ocean fish by collecting water samples and seeing whose DNA was present when.

Recently revised guidelines on mercury in seafood suggest cutting bait on some fish but making sure you eat other types. Then there are omega-3s to consider. Here are some tips to help you choose.
375 million years ago fishes like
Tiktaalik (pictured, above) looked out above water for prey.
John Long, Flinders University
The first truly terrestrial animals evolved from ancient fishes that left the water for land. But what prompted to move has been a mystery.
Some fish build sandcastles to attract a mate but others just use sneaky tactics.
Monstrous, or just misunderstood?

People are more likely to support conservation for cute rather than creepy-looking animals.
The armour of the 380 million year old placoderm fish
Scientists have long believed that our distant cousins are the placoderms, and ancient group of armoured fish. But a new study is casting doubt on that view.
Microplastics can carry other pollutants.

Up to 236,000 tonnes of microplastic enter our oceans each year.
Cities are bright underwater too.

Light pollution is changing the day-night cycle of some fish, dramatically affecting their feeding behaviour.
It's a watery battle of the sexes.
The program can work well for polygamous species such as gorillas.

Computer dating for animals? Finding the right matchup - using DNA rather than personality questionnaires - could help select the best partnerships for captive breeding programs.
A pot of gold? Only if you’re not complacent about the science.

Aquaculture development needs to be able to trust the science, and the science needs to be delivered in a timely way if we hope to ensure long-term sustainability of this industry.
