Invasive shrimp found in English reservoir

摘要

Keen-eyed anglers spotted an unusual shrimp at Grafham Water, a drinking water reservoir in Cambridgeshire, England. The gammarid shrimp was identified as Dikerogammarus villosus, common name 'killer shrimp'. The English Environment Agency immediately worked quickly with Anglian Water to put precau-tionary biosecurity measures in place. This is the first time the shrimp, which is classified as an invasive species, has been found in Britain.
