Sprays and dips blamed for wiping out crayfish
CYPERMETHRIN, used in agricultural sprays and sheep dip, is blamed for polluting one of the remaining strongholds of freshwater crayfish in Britain.
Thousands of Britains only native freshwater crayfish have been killed along a three-mile stretch of the Sherston Avon and Luckington Brook on the border of Wiltshire and Gloucestershire.
The Environment Agency said it feared at least half the population had been wiped out. It is carrying out further tests to pinpoint the source and extent of the pollution.
