Background information and definitions
One of the greatest concerns about invasive crayfishes is their potential to displace native crayfish species, through transmission of crayfish plague or through competitive displacement. A randomised, replicated, controlled, before and after study from the UK (Haddaway et al. 2012) revealed that relocation of a native crayfish Austropotamobius pallipes to avoid the invasive signal crayfish, had no negative effects on growth, survival or morphology of the native species.
