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.
Tilapia guinasana, Otjikoto Tilapia, is a cichlid endemic to Lake Guinas, Namibia, Africa. The species is caught by fishermen for consumption and may be used in aquariums and garden ponds. T. guinasana is listed as a prohibited species in Florida. The history of invasiveness is Data Deficient. There is evidence of an introduced population of Tilapia guinasana causing the extirpation of a native population of fish species. However, the information supporting that claim was not available to be evaluated. The overall climate match for the contiguous United States was low. Areas of medium match were found along the southern border and in southern California. The certainty of assessment is low due to a lack of supporting information on the reported impact. The overall risk assessment category is Uncertain.
