Ecological Risk Screening Summary - Hypostomus meleagris (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 meleagris is a catfish native to the upper Paraná river basin in Brazil, Paraguay, and Argentina. This species has no documented history of introduction in the United States or elsewhere outside its native range, and it is not known to be in trade. However, unidentified species of Hypostomus are established in the United States. History of invasiveness is uncertain. No climate matching analysis was possible because of the lack of georeferenced occurrence information, whether in the form of geographic coordinates or verbal description. Because of the lack of documented introduction history and substantial taxonomic uncertainty, certainty of this assessment is low and overall risk is uncertain.
