Ecological Risk Screening Summary - Hypostomus francisci (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 francisci is a catfish native to the São Francisco and Paraná River basins in Brazil. This species has no documented history of introduction in the United States or elsewhere outside its native range. However, unidentified species of Hypostomus are established in the United States. History of invasiveness is uncertain. H. francisci does not appear to be present in trade in the United States or elsewhere. Climate match to the contiguous United States was low overall, with medium match in parts of Florida, Texas, Arizona, and California. Because of the lack of documented introduction history and substantial taxonomic uncertainty, certainty of this assessment is low and overall risk is uncertain.
