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. This additional information will help inform decisions on where, when, and how the species may be used to minimize risks of them becoming invasive.
C. macropomum is native to the Amazon and Orinoco river basins in South America, but has been translocated to other locations in the Americas, Asia, and Europe for aquaculture and ornamental purposes. Although several individuals have been collected in the continental U.S., no established populations are known. No specific impacts of C. macropomum introduction have been reported; the species may cause injury to humans because of its large size. Climate match to the Continental U.S. is medium, with highest match in southern Florida. Overall risk posed by C. macropomum is unknown.
