I have seen a few American Signal Crayfish in and on the banks of the Basingstoke Canal local to where I live. Can anyone tell me if there is actually a law stating they should be killed if out of the water. I am 100% certain of correct identification and they are not native crayfish.
"Signal crayfish is listed under Schedule 9 to the Wildlife and Countryside Act 1981 with respect to England, Wales and Scotland. As such it is an offence to release or to allow the
escape of this species into the wild. In the UK it is an offence to keep any crayfish without a license, except in some parts of southern England. If trapping of signal crayfish is planned,an application should be made to the relevant environmental protection agency."
