Ecological Risk Screening Summary - Trichomycterus gorgona (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 gorgona is a freshwater parasitic catfish from South America. It has not been reported outside of its native range on Gorgona Island, just off the coast of Colombia. Due to lack of introduction history, the history of invasiveness is uncertain. This species has a uniformly low climate match to the contiguous United States. Due to lack of information about potential impacts of introductions, the certainty of assessment is low. The overall risk posed by T. gorgona is uncertain.
