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.
Tigerfish, Hydrocynus vittatus, is a freshwater predator native to much of sub-Saharan Africa. This species is a popular game fish in its native range and sold commercially for food and within the aquarium trade. Hydrocynus vittatus has not been reported anywhere outside of its native distribution, resulting in an uncertain history of invasiveness. The climate match for the contiguous United States is medium. Florida and Texas scored individually high climate matches and Arizona scored a medium match. All other individual states scored low matches. The certainty of assessment is low due to a lack of information. The overall risk assessment category for Hydrocynus vittatus is uncertain.
