Ecological Risk Screening Summary - Oreochromis mweruensis (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 mweruensis is a tilapia native to Democratic Republic of the Congo and Zambia, Africa. This tilapia is harvested for human consumption in its native range. There is little information available for this species. The history of invasiveness is Data Deficient. O. mweruensis was introduced to a lake in in Rwanda and there is information indicating the species became established; however, no information was found any impacts or lack thereof. O. amweruensis is listed as a prohibited species in Florida. The climate match analysis resulted in a low match for the contiguous United States. There were two areas of medium match, the southern tips of Florida and Texas. There were no georeferenced locations available, so source locations were estimated based on a verbal description of the range. The certainty of this assessment is low due to lack of information. The overall risk assessment category in uncertain.
