Deadly shrimp threat
A so-called killer shrimp has been found in Barton Broad in Norfolk.
It is bad news for anglers as the invasive species - also known as Dikerogammarus villosus - can have a major impact on fish stocks and other wildlife.
The Angling Trust is calling on the Government to take bio-security much more seriously.
The Angling Trust has described the discovery as a 'devastating blow' for anglers who had hoped that the spread had been contained at Grafham Water in Cambridgeshire and two other sites in South Wales.
The highly invasive non-native shrimp originates in the Caspian Region and has spread to other European countries as well.
It predates on native aquatic insect life and fish eggs.The Angling Trust says it's presence could have a major impact on fish stocks and other wildlife.
