Isle of Man anglers warned over 'killer' shrimp

Manx anglers are being urged to be vigilant after a "killer" shrimp was found in a reservoir in East Anglia.

The invasive predator has the potential to destroy native wildlife and reduce biodiversity in Manx rivers.

Anglers who have been to East Anglia are asked to clean all fishing gear before bringing it into the island.

A government spokesman said: "The island would be vulnerable to the invader as its preferred habitat is rocky with fast flowing water".

The Dikerogammarus villosus shrimp can reach up to 3cm in length and has a distinctive striped appearance.

It also has three spikes on its back, which makes it inedible to small fish that choke on the spikes when they try to swallow it.

It was spotted by anglers at the Grafham Water reservoir in Cambridgeshire and sent to the Environment Agency for identification.
