Pacific salmon are ingrained in the culture and economy of Canada. They are also a key link between ocean and land. But what happens if a pipeline failure contaminates their habitat?
Cod and other fish may be unintentionally caught by pulse trawlers.
An expert reviews the research for and against the use of electric pulse trawlers.
The ocean is getting warmer and more acidic but changing our diet could help us cope.
Canned tuna is an Australian pantry staple.
Australians love canned tuna. Here's our handy guide to finding the most sustainable options for you (and your cat).
The sea remains the least explored habitat on our blue planet.
There's plenty of evidence that even fish have feelings.
Pacific seabirds, such as this Great Blue Heron, can accumulate mercury in their bodies from the fish they eat.
Mercury levels in seabirds living off the coast of British Columbia have been stable in recent years. New research suggests that this may be due to changes in their diet, not pollution control.
The evidence shows that both low and high fat diets can reduce your risks of cardiovascular disease – if they are plant-based.
From donuts to avocados, food impacts your heart health. Here we delve into the science of how to eat -- to reduce your chances of cardiovascular disease.

Plastic trash on San Francisco’s Ocean Beach.

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.
