Ecological Risk Screening Summary - Oreochromis lidole (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 lidole is a tilapia native to the southern portion of Lake Malawi in Malawi. This is a mouth brooding species that has been historically included in the commercial ‘chambo’ fishery in Lake Malawi. The species has not been recorded since at least 2007 and is considered to be possibly extinct. O. lidole is listed as a prohibited species in Florida. The history of invasiveness is no known nonnative population. It has not been reported as introduced or established outside of its native range. The climate match analysis resulted in a low match for the contiguous United States. The only areas of medium match were found in southern Florida, Texas, and Arizona. The certainty of this assessment is low due to lack of information. The overall risk assessment category in uncertain.
