Ecological Risk Screening Summary - Trichomycterus paolence (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 paolence is a species of trichomycterid catfish that has been subject to very limited study. Its known distribution is southern Brazil. There is little information on the biology of the fish. T. paolence is regulated in multiple States. There have been no reports of the species outside of its native range. Therefore, the history of invasiveness is classified as No Known Nonnative Population. The overall climate match to the contiguous United States is Medium. Much of the contiguous United States had low local matches; small areas of high match were found in Florida. The certainty of assessment is Low due to a general lack of information. The overall risk for this species is Uncertain.
