The rusty crayfish (Faxonius rusticus) is an invasive crayfish species native to North America, with limited presence in the UK but considered a potential ecological threat. Known for its aggressive behaviour and high reproductive rate, the rusty crayfish can outcompete native crayfish species, disrupt aquatic vegetation, and alter ecosystem dynamics. It is also a carrier of crayfish plague (Aphanomyces astaci), further threatening native populations.
April, May, June, July, August, September
Biosecurity surveillance is warranted. Active between April and September if present with peak eDNA detection probability between May and August. Nocturnal sampling recommended.
