Public Urged to Report Invasive Signal Crayfish Sightings
Members of the public are urged to report any sightings of Signal Crayfish after the species was spotted near the Bridgewater Canal at Stockton Heath, Warrington.
Signal crayfish are an invasive species in the UK, identifiable by their reddish-brown color and distinctive pale blue-white "signal" spot on the claw joint.
- They are larger than the native white-clawed crayfish.
- They carry the crayfish plague, a disease lethal to native white-clawed crayfish.
- They prey on native species, compete for food and habitat, and can significantly impact local fish stocks.
Do not touch or remove them if you spot invasive crayfish.
To report sightings, call the Environment Agency’s 24-hour hotline: 0800 807060.
