正文(英文) | Press release Project to protect native White-clawed crayfish in DerbyshireEnvironmental forces mobilised to deal with American Signal Crayfish invasion ![]() An American Signal Crayfish, fished out of Derbyshire lake A partnership project to conserve native white-clawed crayfish in Derbyshire has completed its second successful year with the removal of 2,000 non-native invasive signal crayfish from Markeaton Lake in Derby – double the amount it removed in 2018. The Signal Crayfish Removal Project led by the National Trust, aims to support the recovery of white-clawed crayfish by preventing signal crayfish from expanding into the upstream Markeaton Brook and Kedleston Lakes where the native species are known to be found. Native white-clawed crayfish have been in decline since non-native American signal crayfish escaped into UK waters in the 1970s. These larger, invasive crayfish outcompete native species for food and habitat and carry a disease fatal to the UK species. Louise Hill, Biodiversity Officer at the Environment Agency in the East Midlands said:
Carl Hawke, Regional Nature Conservation Advisor at the National Trust said:
White-clawed crayfish, named for the pale colour of the underside of their claws, are the country’s largest native freshwater crustaceans. Generally growing to 30 – 40mm in length, some can live up to 12 years and reach 120mm long from tip to tail. Invasive species pose a serious threat to our native wildlife and cost the UK economy £1.8 billion a year. Everyone can do their part to prevent the spread of invasive species and protect native ones by taking care to follow the biosecurity steps of thoroughly checking, cleaning and drying their clothes and equipment any time they have been in the water.
