Ecological Risk Screening Summary - Metynnis lippincottianus (a fish, 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.

Metynnis lippincottianus is a freshwater fish native to the Amazon River basin and northeastern Guiana Shield rivers of South America. It has been introduced and appears to be established in other areas of Brazil. M. lippincottianus has also been observed in Florida, where it is currently in trade. It is not known whether this species has established in Florida. Impacts of this species have not been documented; the only information available is on the negative impacts of M. lippincottianus as part of a group of nonnative species, so it is unclear to what extent M. lippincottianus itself contributed to the negative impacts. The climate match with the contiguous United States is medium, with the highest matches in the Southeastern United States, especially in Florida and along the Atlantic and Gulf Coasts. Certainty of assessment is low. The overall risk assessment category for Metynnis lippincottianus is uncertain due to limited information about the impacts of this species.
