Ecological Risk Screening Summary - Magadi Tilapia (Alcolapia alcalica) - 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.

The history of invasiveness is uncertain. A single record of introduction was found but no details were provided and the validity of that record is in question. The climate match was low. Climate 6 was 0.000. There were very small areas of medium climate match in southern Texas, in the southwest, and along the west coast. Alcolapia spp. as a whole are specialized to alkalinity levels that would kill most other fish. It is uncertain how that physiology would affect their ability to successfully establish a population in the United States. The certainty of assessment is medium. The overall risk assessment category is uncertain.
