Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
Cherax peknyi is a crayfish from Papua New Guinea. The species has an overall low climate match to the contiguous U.S. and has no history of introduction outside its native range. However, C. peknyi is one of the most common species in the pet trade in the Czech Republic and has been found in the pet trade in the United States as well. The States of Florida and Washington prohibit possession or trade of this species, along with other Cherax crayfish. The overall risk assessment is uncertain.
