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.
Berg-Breede Whitefish (Cheilobarbus capensis) is an endemic whitefish native to the West Cape of South Africa. C. capensis is used in local aquaculture and is considered a game fish; at the same time its population seems to be declining and it is listed as a threatened species in South Africa with legal protections. It is considered to be extinct in part of its historical native range. It has never been documented as introduced or established outside of its native range; therefore, its History of Invasiveness is classified as No Known Nonnative Population. Cheilobarbus capensis has a High Overall Climate Match with the contiguous United States; the area of highest match was in the west, especially California. Certainty of this assessment is Low due to the complicated taxonomic history and a lack of information regarding the history of invasiveness. The overall risk assessment category is Uncertain.
