Ecological Risk Screening Summary - Pristobrycon striolatus (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 striolatus is a species of piranha native to Atlantic river basins in South America from the Orinoco to the Amazon. It eats seeds and fruits as well as fish fins and is used as a food source in Brazil. The history of invasiveness is classified as “no known nonnative population.” No records of introduction were found. P. striolatus is regulated in multiple States. The climate match was low. There were small areas of medium match around the Gulf Coast along with medium matches for southern Florida and a high match at the very southern tip of Florida. The certainty of assessment is low. The overall risk assessment is uncertain.
