Ecological Risk Screening Summary - Metynnis guaporensis (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 guaporensis is a freshwater fish native to South America. It is not known to be introduced outside of its native range, leading to a history of invasiveness classification of uncertain. However, members of the Metynnis genus (species uncertain) have been collected beyond their native range in Florida, where their status is listed as locally established. M. guaporensis has a low climate match with the contiguous United States, with the highest matches in southern Texas and peninsular Florida, and a low match throughout the rest of the contiguous United States. This species is not known to be in trade, although it is permitted by the Brazilian government to be used in the ornamental fish trade. Certainty of this assessment is low due to limited availability of information about M. guaporensis and taxonomic uncertainty. The overall risk for M. guaporensis is uncertain.
