Ecological Risk Screening Summary - Trichomycterus vermiculatus (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 vermiculatus is a small catfish native to the Paraíba do Sul River in Brazil. Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. History of invasiveness is uncertain because this species has not been documented outside of its native range. More information is needed to adequately assess the risk this species poses in introduced areas; absence of this information makes the certainty of this assessment low. T. vermiculatus has a medium climate match with the contiguous United States. Most of the contiguous United States had a low match, except for peninsular Florida and the Gulf Coast of Texas. Overall risk posed by this species is uncertain.
