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 nyongana is a benthopelagic cichlid native to river systems in Cameroon and Gabon. The species has not been reported as introduced outside of this area. Because T. nyongana has no history of invasiveness, it is currently impossible to know what impacts T. nyongana might have if introduced to the U.S. To date, the species is known to be susceptible to intestinal parasites but not to any OIE-notifiable diseases. Climate match to the contiguous U.S. is low. Overall risk of this species is uncertain.
