Ecological Risk Screening Summary - Serrasalmus medinai (a piranha, 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.

Serrasalmus medinai is a piranha native to the Amazon and Orinoco River basins in Venezuela and Colombia. It is present but rare in the aquarium trade in the United States. Numerous U.S. States prohibit the possession or trade of piranhas. No introductions of S. medinai have been reported, so impacts of introduction remain unknown for the species. History of invasiveness is classified as No Known Nonnative Population. Certainty of assessment is low due to a lack of information. The climate match to the contiguous United States was low overall, with medium matches occurring in southern Florida. Overall risk posed by S. medinai is Uncertain.
