Ecological Risk Screening Summary - Tridensimilis venezuelae (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.

Tridensimilis venezuelae is a parasitic catfish native to the Lake Maracaibo basin in Venezuela, on the border with Colombia. This species has a low climate match to the contiguous United States. It has not been documented as introduced outside of its native range, so history of invasiveness is uncertain. Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. There is very little information available about this species, so the certainty of this assessment is low. The overall risk assessment category of this species is uncertain.
