Ecological Risk Screening Summary - Oreochromis tanganicae (a tilapia, no common name) - 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.

Oreochromis tanganicae is a tilapia endemic to Lake Tanganyika and surrounding rivers in Burundi, Democratic Republic of the Congo, Tanzania, and Zambia, Africa. This species supports a small commercial and subsistence fishery in the native range. The history of invasiveness is Data Deficient. O. tanganicae was introduced to areas outside of the native range in Burundi and became established. However, no reports of impacts were found. O. tanganicae is listed as a prohibited species in Florida. The climate match analysis resulted in a low match for the contiguous United States, with small areas of medium match in southern Florida and Texas. The certainty of this assessment is low due to a lack of information. The overall risk assessment category in uncertain.
