Ecological Risk Screening Summary - Pristobrycon aureus (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.

Pristobrycon aureus is a species of fish that is native to the Amazon River basin and rivers in Guyana. P. aureus has an herbivorous diet. The history of invasiveness is classified as “no known nonnative population.” There were no records of introduction found for P. aureus and therefore no information on impacts of introduction. This species is regulated in multiple States. The climate match for the contiguous United States is low with only one small area of medium match along the coast of Florida. The certainty of assessment is low. The overall risk assessment is uncertain.
