It’s been reported that American Mink are running riot on Britains Waterways including areas of Surrey.
Environmentalists say the animals can kill hundreds of native species every year and local anglers have been asked to help eradicate them.
Members of the Dorking and District Angling Society will be acting as eyes and ears along a stretch of the River Mole to protect water voles, swans and herons.
If anyone spots an American Mink, they pass on the location to the Waterlife Recovery Trust who will then take suitable action.
