Aren't they the invasive silver carp they've had so much bother with over there? A prime example of why we shouldn't ****** about with nature.
Yep, that's them! Our club had a recent netting of a lake in Cheshire and as well as hundreds of normal carp and bream they caught a 44lb catfish that was re-homed in a licensed water and 2 silver Asian Carp at 31lb and 32lb. As is required by law the EA were informed and they took them away for destruction.
