Ecological Risk Screening Summary - Oreochromis amphimelas (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 amphimelas is a native fish to Africa. There is little information available for this species. The history of invasiveness is classified as “No Known Nonnative Population.” Shechonge et al. (2018) reports O. amphimelas as expanding from its native range, without explicitly stating that it is due to non-native introductions, but with no reports of impacts. The climate match analysis resulted in a low match for the contiguous United States. The certainty of this assessment is low. The overall risk assessment category in uncertain.
