Ecological Risk Screening Summary - Serrasalmus auriventris (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 auriventris, is a piranha native to the Río Paraná in Argentina. Although considered a valid species by Eschmeyer et al. (2018), the only report of this species is the original identification, and no type specimens are known. This species has not been reported as introduced outside its native range, so the history of invasiveness is classified as No Known Nonnative Population. Along with other piranhas, the importation, possession, or trade of this species is prohibited or restricted in numerous States. The climate match was medium overall for the contiguous United States, with a high match for the States of Florida and Texas and a medium match for the State of Georgia. The lack of introduction history, biological information, georeferenced points and doubts about taxonomy lead to a low certainty of assessment. The overall risk assessment for Serresalmus auriventris is Uncertain.
