How to catch and cook signal crayfish

George Monbiot has put together this step-by-step guide with photos about how to catch and cook the dreaded red-clawed signal crayfish (Pacifastacus leniusculus), a large, aggressive American species that has wiped out almost 95% of the native white-clawed species (Austropotamobius pallipes) since it was introduced to the country in the late 1970s.

Plan to save British crayfish

A £210,000 breeding programme has been started to save Britain’s rare native white-clawed crayfish. The species (Austropotamobius pallipes) is in danger of being wiped out by invasive American signal crayfish, which carry a disease, crayfish plague, which is fatal to the British species. The crayfish are being bred at secret locations in the south-west of England. American crayfish were introduced in the UK twenty years ago for farming. This has since led to the disappearance of almost 95% of the native species, which faces extinction from UK waters within 30 years unless new populations can be created in safe, uncontaminated waters.
