Killer shrimp discovered in the Norfolk Broads

A dedicated monitoring programme has revealed small numbers of the Killer shrimp, Dikerogammarus villosus, in an area of Barton Broad, Norfolk. This is a highly invasive non-native species, currently known only from three other sites in England and Wales. If the shrimp became established and widespread in the UK it could pose a serious threat to native species. See the Environment Agency press release for information.
All users of the Broads are urged to follow Check Clean Dry guidance for all equipment that has been in contact with the water. Killer shrimp sightings should be reported immediately to alert_nonnative@ceh.ac.uk.
