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.
Cambarellus puer is a freshwater crayfish native to east-central Texas, eastward through the coastal plain to the Mississippi basin and from the lower part of the Mississippi Delta to Johnson County, Illinois. It is reported to be rarely available on the market for wholesale trade in the Czech Republic, where it has a potential invasiveness (FI-ISK score) of 3 and a risk category (FI-ISK Category) of Medium. Data on impacts of introductions are lacking. Absence of this research makes the certainty of this assessment low. Climate match with the United States is high. Overall risk posed by this species is uncertain.
