Take our crab cleaning survey

There have been many reports of good-sized blue swimmer crabs caught in the Swan and Canning rivers this season, but did you know that crabs caught in these rivers have the potential to contain a toxin produced by Alexandrium, a type of alga which can bioaccumulate in their guts?

The best advice to avoid the toxin and stay safe is to not eat mussels at all, and to take your catch of blue swimmer crabs home whole, then clean them by removing the head, guts (mustard) and gills before you freeze, cook or eat them.

To help us ensure the message about cleaning crabs is getting out to where it is needed, we would appreciate crab fishers complete a short anonymous survey. https://www.cognitoforms.com/DepartmentOfPrimaryIndustriesAndRegionalDevelopment/AlexandriumCrabCleaningSurvey2021

You can also help others stay safe by spreading the word about cleaning your crabs. There are instructional flyers available in four languages from this website, and a short video of the step by step process to clean blue swimmer crabs, which you can show to friends and family.
