Ecological Risk Screening Summary - Setose Yabby (Cherax setosus) - Uncertain Risk

Cherax setosus is a crayfish native to the central coast of New South Wales, Australia. It was only recently defined as a unique species, previously having been considered a subspecies of C. rotundus or C. destructor. As a result, little information is available on C. setosus. No introductions of this species are known, so there is no known history of invasiveness. Along with nearly all other Cherax crayfish species, the State of Washington prohibits possession, sale, and transport of C. setosus because of perceived risk that the species could become invasive if introduced. Climate match to the contiguous U.S. for C. setosus showed the most suitable climates occurring in Florida and Texas, with a medium match overall. Because of the lack of introduction history, overall risk posed by C. setosus is uncertain.
