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 angolensis is a tilapia endemic to the Bengo and Cuanza river systems in Angola. It can be found in fresh and brackish water, but not much is known about the biology and ecology of this species. There are no records of introductions. The history of invasiveness is classified as “No Known Nonnative Population.” The climate match was low with a small area of medium match in southern Florida. The certainty of assessment is low and the overall risk assessment category is uncertain.
