Ecological Risk Screening Summary - Tanzanian Tigerfish (Hydrocynus tanzaniae) - 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 Tanzanian tigerfish (Hydrocynus tanzaniae) is a freshwater fish endemic to Tanzania. H. tanzaniae can be found in the Wami, Ruaha and Rufiji Rivers. H. tanzaniae has not been reported anywhere outside of its native range, thus the history of invasiveness is uncertain. The climate match for the contiguous United States was low. There was one small area of medium match in southern Florida. The certainty of assessment is low due to limited information. The overall risk assessment category for H. tanzaniae is uncertain.
