Ecological Risk Screening Summary - Trichomycterus nigroauratus (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 nigroauratus 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. No records of this species in trade were found. T. nigroauratus 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 Low. Peninsular Florida had a medium match. The certainty of assessment is low due to a general lack of information. The overall risk for this species is Uncertain.
