Crabs are ten-legged crustaceans with species found in all oceanic regions as well as freshwater and on land. As food, crab is prized for its delicate flavour and low fat content.

What is a crab?

A crab is a decapod (10-legged) crustacean, which generally has a thick shell (exoskeleton) and a single pair of pincers.

Are crabs sustainable?

There is no such thing as a sustainable species of fish. Only sustainable populations of fish.

As of July 2022, there are 12 MSC certified crab fisheries around the world, including from Australia (crystal crab and blue swimmer crab), Canada (snow crab), the Gulf of Mexico (blue crab) and Shetland in Scotland (brown crab).

About 9% of the global crab catch is independently certified to the MSC Fisheries Standard.

Crabs caught for human consumption are harvested in traps.
