Ecological Risk Screening Summary - Trichomycterus potschi (a catfish, no common name) - Uncertain Risk

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.

Trichomycterus potschi is a species of catfish that has been subject to very limited study. Its known distribution is the coastal basins between Mangaratiba and Itaguaí in southern Brazil. There is little information on the biology of T. potschi. Trichomycterus potschi is regulated in multiple states. The history of invasiveness is classified as No Known Nonnative Population. There have been no reports of the species outside of its native range. The climate match to the contiguous United States is medium. However, much of the United States had a low match, except the Gulf Coast of Texas and Florida, which had a medium to high match. No georeferenced points were available for the climate match, so it was based on the described range. The certainty of assessment is low. The overall risk for this species is Uncertain.
