From the BBC:
Breeding ‘success’ for crayfish
The white-clawed crayfish is one of England’s most threatened species.
Natural England and the Environment Agency are seeking funding to expand the programme, which began in 2003.
The white-clawed crayfish was once common in upland rivers and streams but is being driven out by its invasive cousin, the American signal crayfish.
The more aggressive American species, which was brought to the country to be farmed, also carries a “plague” which is fatal to the native crayfish.
