## Summary

The U.S. Fish and Wildlife Service wants to stop certain freshwater mussels and a crayfish from invading U.S. waters by banning their import and movement without special permission. This protects native wildlife and ecosystems from harm. People and businesses dealing with these species should know comments are open until March 11, 2025, with no immediate costs but big environmental benefits.

## Abstract

The U.S. Fish and Wildlife Service (Service) proposes to add all species of freshwater mussels from two genera, Asian pond mussels (Sinanodonta species) and golden mussels (Limnoperna species), to the list of injurious mollusks. Additionally, the Service proposes to add marbled crayfish (Procambarus virginalis) to the list of injurious crustaceans. Listing these taxa as injurious will prohibit the importation of any live animal, larvae, viable egg, or hybrid of these taxa into the United States, except as specifically authorized. These listings would also prohibit shipment of any live animal, larvae, viable egg, or hybrid of these species between the continental United States, District of Columbia, Hawaii, Commonwealth of Puerto Rico, or any territory or possession of the United States, except as specifically authorized. The action is necessary to protect wildlife and wildlife resources by preventing the introduction and subsequent establishment of these foreign aquatic invertebrates into ecosystems of the United States.

## Effects PRIA read

- Import and Interstate Shipment Ban: cost, low. The Service proposes to ban importation into the United States and shipment between the continental U.S., District of Columbia, Hawaii, Puerto Rico, and U.S. territories of any live animal, larvae, viable egg, or hybrid of Asian pond mussels (Sinanodonta spp.), golden mussels (Limnoperna spp.), and…
- Permits Allowed for Research and Agencies: benefit, low. The proposed listing would still allow importation or shipment of these listed taxa if specifically authorized under permit terms (for zoological, educational, medical, or scientific purposes under 50 CFR 16.22) or for Federal agencies for their own use.
- Protects Wildlife, Farming, and Water Infrastructure: benefit, high. The Service proposes the listings to prevent introduction and establishment of these invasive aquatic invertebrates so they do not harm wildlife and wildlife resources, agriculture (including aquaculture), or water infrastructure such as hydropower.
- Intrastate Transport and State Authority Preserved: mixed, low. The proposed federal listings would not prohibit transport of these taxa within an individual State, and any State rules about possession, transport, or use within a State would remain the authority of that State.
- Final Listing Scope May Vary: mixed, low. The Service may confirm for listing in the final rule one, some, or all of the individual species proposed within the Sinanodonta and Limnoperna genera and the marbled crayfish; the final rule may therefore narrow or confirm the specific taxa listed.
