Ecological Risk Screening Summary - Oreochromis shiranus (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 shiranus is a tilapia native to the Lake Malawi basin in Africa. O. shiranus is a staple species in the aquaculture industry in southern Africa. The history of invasiveness is no known nonnative population. O. shiranus was introduced in Madagascar, however no records indicate that a population was established. The climate match analysis resulted in a low match for the contiguous United States, with small areas of medium match in southern Florida, Texas, New Mexico, and California. The certainty of this assessment is low due to a lack of information. The overall risk assessment category in uncertain.
