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 Nile Tiger-fish (Hydrocynus forskahlii) is a freshwater fish native to 27 countries distributed throughout Africa. This species has not been recorded as introduced or established anywhere in the world outside of its native range. The climate match for the contiguous United States is medium. Arizona, California, and Florida scored high climate scores, while Nevada and Texas scored medium scores, with the rest of the States receiving low individual scores. The certainty of assessment is low. The overall risk assessment for H. forskahlii is uncertain.
