Species that are considered high risk have a well-documented history of invasiveness in at least one location globally, and a high or medium climate match to the contiguous United States.
Culter alburnus is a cyprinid fish native to Mongolia, mainland China, Russia, and Taiwan. It has not been reported in the United States, but it has been introduced outside its native range in Taiwan and Russia. In both locations, the species quickly achieved high abundance within the fish community. In Taiwan, C. alburnus was observed to heavily predate a native fish species and was likely responsible for substantially reducing the native species’ abundance and changing its population size structure. C. alburnus is a popular species for commercial and sportfishing in China. Climate match for the continental U.S. was high, with highest match occurring in the North-Central U.S. Overall risk posed by C. alburnus is high.
