"Crayfish plague" is a pathogen that is normally carried by North American crayfish and has adversely affected crayfish populations in Europe and elsewhere. it would not affect NA populations (in general) nor would it be spread from an invasive or exotic being released here.Sakon;1188398; said:Crayfish plague is a disease that occurs when a non-native species is introduced into the wild.
