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 nigricans is a cyprinid fish species native to the Democratic Republic of the Congo. Climate match to the contiguous United States is low, with areas of medium match in Florida and Louisiana, although the native range may be larger than what is represented among the source locations used for climate matching. Very little is known about the biology and ecology of L. nigricans. Certainty of assessment is low. L. nigricans is caught and consumed by humans, but no history of introduction has been reported. Without any information on past introductions and their impacts, the overall risk assessment category for L. nigricans is “Uncertain”.
