Ecological Risk Screening Summary - Trichomycterus dispar (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 dispar is a freshwater parasitic catfish from South America. It has not been reported as introduced anywhere outside its native range in Peru and Ecuador. Due to the lack of introduction history, the history of invasiveness is uncertain. This species had a low overall climate match with the contiguous United States, with medium matches only in far southern Texas and southern coastal California. Due to lack of information about potential introductions, the certainty of assessment is low. The overall risk posed by this species is uncertain.
