Due to the American crayfish plague, crayfish of this genus have been almost wiped out in Europe and have in many European countries been replaced by the North American signal crayfish, which is resistant to the plague. This, often illegal, implantation of signal crayfish has made it very difficult to reintroduce Astacus in the wild since the signal crayfish, although resistant, does carry the plague and infects lakes and rivers it inhabits.
