Ecological Risk Screening Summary - Hypostomus commersoni (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.

Hypostomus commersoni is an armored catfish that is native to southern South America. One source stated that the species is found in the aquarium trade but no specific trade information was available and no records of the species in trade in the United States were found. The history of invasiveness is uncertain. No records of introduction were found so there is no information on impacts of introduction. The climate match was high. The high climate match was focused on the south, particularly the southern Atlantic and Gulf coastal areas. The certainty of assessment is low. The overall risk assessment category is uncertain.
