Ecological Risk Screening Summary - Hypostomus boulengeri (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 boulengeri is a suckermouth catfish native to the Paraguay, Paraná, and Bermejo Rivers in central South America. The history of invasiveness is uncertain because no records of introductions were found. Therefore, there is no information on impacts of introduction. H. boulengeri had a medium climate match with the contiguous United States. There was a high match in Florida and along the Gulf Coast. The certainty of assessment is low. The overall risk assessment category is uncertain.
