Disastrous news from Dr Ben Rushbrooke at Hants &IOW Wildlife Trust that signal crayfish have been found at the very top of the River Itchen, at the upper limit of the known distribution of native white-clawed crayfish on the Alre, placing the entire subpopulation of the native species in very real and immediate risk.
Ben and colleagues are planning action but it is a timely reminder for anglers of the need for biosecurity: CHECK, CLEAN & DRY all your gear after every trip.
