Ecological Risk Screening Summary - Trichomycterus variegatus (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 variegatus is a small parasitic catfish native to the São Francisco River basin in Brazil. History of invasiveness is uncertain because this species has not been documented outside of its native range. Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. Certainty of this assessment low due to lack of information. T. variegatus has a low climate match with the contiguous United States. The overall risk posed by this species is uncertain.
