Ecological Risk Screening Summary - Trichomycterus plumbeus (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 plumbeus is a species of 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. Trichomycterus plumbeus 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 low, with areas of medium match found primarily along the Gulf and southern Atlantic coasts. The certainty of assessment is low due to lack of information. The overall risk for this species is uncertain.
