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.
Labeo umbratus is a cyprinid fish native to South Africa, Lesotho, and Namibia. The species has become established in additional river basins within South Africa through inter-basin water transfer schemes and perhaps movement by anglers as bait. Inter-basin transfer schemes have also connected historically isolated populations of the species which may have resulted in hybridization between these populations. Otherwise, no impacts of introduction have been reported yet. Climate match to the contiguous U.S. is high. Overall risk posed by L. umbratus is uncertain.
