As more and more plastic trash permeates the oceans, fragments are making their way into fish and shellfish – and potentially into humans.
Sardines are rich in oils and protein.

The oils in fish are excellent buffers against disease. Why don't we eat more fish?
New research points to 'heavy metals' having unseen effects on a much larger scale than previously thought.
Parasites do very well for themselves, which is why they are so common in the animal kingdom.
Mud blister worms make their homes in the shells of oysters and other shellfish, where they weaken their hosts.

Growing demand for large salt-water clams is leaving parts of the B.C. coast littered with plastic debris.
Shrimp cocktail: Tasty to some, potentially deadly for others.
Alongside with milk, eggs, peanuts, tree nuts, wheat, soybeans and fish, shellfish are one of the eight allergens that account for 90% of food-related allergic reactions. What if a vaccine could exist?
Acidic seawater conditions are interfering with the ability of shellfish to produce strong, resilient shells, and it's happening all over the world.
Gulf Coast oysters on the half shell at Wintzell’s, Mobile, Ala.
Oysters are big business along the Gulf Coast, but raising them off-bottom – which yields a premium product – is just starting there. Hurricane Michael showed it won't be easy.
Remains of meals at Haua Fteah cave reveal a lot about past climates in in the Gebel Akhdar region of Libya.
Archaeologists are trash sifters. They use clues preserved in artefacts, plant and animal remains that people threw away or left behind to reconstruct the past.
Oysters can do a lot more than they’re given credit for.
Oysters aren't just good for a feed. They also give a vital boost to coastal ecosystems, which is why efforts are underway to restore Australia's once-abundant oyster reefs to their former glory.
The ocean is getting warmer and more acidic but changing our diet could help us cope.
Colleen Burge counts oysters on an oyster aquaculture lease in California.
Oysters grow in seawater and filter their food from it, so how do you shield them from waterborne diseases? Scientists are working to develop strains that are resistant to a fast-spreading herpes virus.
Pike Place Market, Seattle.
A new study shows that sustainable fish farming in deep ocean waters could produce as much seafood as all of the world's wild fisheries, in a space the size of Lake Michigan or Africa's Lake Victoria.
Mud oysters played a largely unappreciated part in Australia’s history.
In colonial times Australia's waters were teeming with mud oysters that provided food, cement, and cleaned the oceans. Now a 20-hectare man-made reef aims to restore some of their former glory.
Some sea animals with smooth shells can dig themselves into the sand in just a few seconds.
Maëlle, 7, wants to know why some shells are smooth, while others are corrugated. It turns out that while corrugated shells are strong, smooth shells can move fast.

Global climate change is altering the chemistry of the oceans. A recent study suggests that the Pacific coast's lucrative Dungeness crab fishery could suffer as ocean water becomes more acidic.
The mussel hustle.
Shellfish will have more brittle shells as oceans get more acidic – making them more vulnerable to predators. New research gives a fascinating glimpse into how they will adapt.
From boom to bust: tiger prawn farming.
The tropical island was one of a number of countries that joined the goldrush of prawn farming in the 1980s and 1990s. New research lays plain the results.
Vomiting since 500-470 BC.
As I was growing up, any time my mother suggested buying mussels or cockles for dinner, my gran would pipe up with the old adage that “you should only be eating shellfish when there’s an ‘R’ in the month…
Food from the Stone Age has raised doubts about the causes of the human revolution.
About 50,000 years ago, modern humans left Africa and began occupying the rest of the world. The common thought is that a…
