Are crabs sustainable?

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.

Blue swimmer crabs (Portunus armatus), also called ‘blue manna’ or ‘blueys’, are a dinner table favourite. They yield about 35% meat, and have a mild, sweet, nutty flavour. They're found in coastal waters and are a popular species with recreational fishers. 

Crystal crabs, also called snow crabs, are a deep sea species found off the coast of Western Australia. Their soft, edible shell, succulent white flesh and sweet flavour have made them a favourite in Chinese restaurants and Asian export markets.

How do I know if crabs are sustainable?

Crabs carrying the MSC blue fish tick are certified sustainable. MSC labelled crabs come from a fishery that has been independently assessed to the MSC Fisheries standard. Companies using the blue fish tick all along the supply chain have been assessed to ensure products can be traced back to an MSC certified fishery.

Where can I buy sustainable crabs?

You’ll find blue swimmer crabs with the blue fish tick available locally in Mandurah, Western Australia, from retailers including Wattsies Place. 

The Peel Harvey Estuary, south of Perth, Western Australia, made history as the world’s first shared commercial and recreational fishery to jointly achieve MSC certification and carry the MSC blue fish tick. Close to 100 tonnes of crab a year are landed by commercial fishers, all of which are sold locally, and similar amounts are caught by recreational fishers.
