Red swamp crayfish seized

​The highly invasive red swamp crayfish is a declared noxious species which, if introduced into local waterways, poses an extreme risk to our native crustaceans. There are significant penalties if people are found to keep, breed, hatch, culture, possess, consign, convey or release declared noxious fish, with fines of up to $10,000.

In a recent operation by fisheries officers, supported by the WA Police force, 70 of these noxious freshwater crayfish were seized in the Bunbury and Capel areas during Operation Winterfox

Red swamp crayfish can range in length from 5–12 cm, can be dark to light red, with rows of bright red bumps on the front and side of the first leg. If you think you may have seen any, or have information about any noxious fish being kept or traded, report it anonymously to Fishwatch on 1800 815 507 or send an email to

You can help minimise the risk of noxious fish impacting on WA’s aquatic environment. Never dispose of or release unwanted or illegal aquarium animals into any waterways or drains, and dispose of dead aquarium animals by securing them in a plastic bag and placing them in a household rubbish bin for council landfill.
