Public Urged to Report Sightings of Invasive Signal Crayfish

Members of the public are urged to report any sightings of Signal Crayfish, after the invasive species was spotted near the Bridgewater Canal at Stockton Heath, Warrington.

Signal crayfish are an invasive species in the UK, larger than the native white-clawed crayfish, and can be identified by their reddish-brown colour and distinctive pale blue-white "signal" spot on the claw joint.

Do not touch or remove them if you spot invasive crayfish.

To report sightings, call the Environment Agency’s 24-hour hotline: 0800 807060.
