Fisheries

The Minister is right to highlight the rich and diverse ecosystem for which he is responsible. In my constituency we have an invasion of signal crayfish, an American type of crayfish that is driving out white crayfish—the British crayfish. As I understand it, permission for the introduction of that species was given by the Environment Agency. Should we not be very cautious when we allow non-native species to be introduced because of the potential effect on the ecosystems that we treasure?
