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.
Hydrocynus goliath, also known as the giant tigerfish, is a large fish indigenous to the Congo River Basin and Lake Tanganyika in Africa. Despite having a history of attacking and harming humans, it is a popular gamefish and target of commercial fishing. Information on the biology and distribution of this species is not readily available. No reports of introductions beyond its native range were found. The climate match for the contiguous United States is low, with only the Florida peninsula and coastline of the Gulf of Mexico representing a medium match. The State of Florida has listed H. goliath as a prohibited species. Given all factors, the assessment for this species is uncertain.
