11 Freshwater Species: 10 fish and 1 crayfish  (October 29, 2015)

The U.S. Fish and Wildlife Service is announcing a proposed rule on October 30 to add 11 nonnative freshwater species to the list of injurious species. There are 10 fish (crucian carp, Eurasian minnow, Prussian carp, roach, stone moroko, Nile perch, Amur sleeper, European perch, zander, wels catfish) and 1 crayfish (common yabby). 

The proposed rule opens a public comment period that ends on December 29, 2015 (please see the proposed rule for how to submit public comments). We are also making the associated draft environmental assessment and draft economic analysis for this action available for public review and comment. These 11 species are not in U.S. trade or are in negligible trade, and we expect there to be only a minor, if any, effect on the U.S. economy if these species are listed. The 11 species have the potential to become highly invasive if introduced into the wild in the United States and cause harm to our freshwater habitats and our native species, as well as to the local economies these natural resources support. Therefore, the Service is taking this proactive step to keep these species out of the country before they have a chance to become invasive.

Ecological Risk Screening Summaries (ERSSs)

Supplemental climate match maps (including Alaska, Hawaii, and the U.S. territories)

These maps were used to determine the climate match in the proposed rule. These maps were based on a broader geographic area (including Alaska, Hawaii, and the U.S. territories) than the maps in the Ecological Risk Screening Reports (ERSS) reports above, which were based on the lower 48 States (although the Nile perch ERSS map includes more).  These supplemental maps also may include some updated information.
