Ecological Risk Screening Summary - Striped Silver Dollar (Metynnis fasciatus) - 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.

The striped silver dollar (Metynnis fasciatus) is a fish native to Brazil. This species is not known to be established outside of its native range. 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. Metynnis spp. found in Florida are believed to be aquarium releases. M. fasciatus is in the aquarium hobby trade, and is bred in Florida. The lack of information about impacts of introduction leads to an uncertain classification for history of invasiveness. The climate match with the contiguous United States for this species was low, with a small area of medium match in southwest Florida. Certainty of this assessment is low due to a lack of information and taxonomic uncertainty. The overall risk assessment category for Metynnis fasciatus is uncertain.
