Introduced to the UK as a food species in the 1970's these crustaceans escaped from their landlocked ponds into Britains rivers and rapidly spread. They are carriers of "crayfish plague" which has attacked the UKs native crayfish and depleted their numbers greatly. In addition they threaten fish stocks through predating on their eggs and damage banks by their habit of burrowing into them.

Far too many! They are a pest and endanger the survival of the native crayfish.
Please contact the environment agency for advice on catching them and removing them from any where you find them
It is illegal to return a signal crayfish to any English water

What are signal crayfish anyway? Miniature U-Boats?
