Dikerogammarus villosus, sometimes known as the 'killer shrimp', is an invasive non-native species that has spread from the Ponto-Caspian Region of Eastern Europe. As a voracious predator it kills a range of native species, including young fish, and can significantly alter ecosystems. It is present at three locations across England and Wales and has not yet been discovered elsewhere.
A new briefing note to keep stakeholders informed of developments relating to the Killer Shrimp (Dikerogammarus villosus) is now available. In addition, the Environment Agency has compiled a factsheet summarising the most relevant facts about this species. CEFAS have also reported on biosecurity treatments used for the killer shrimp.
