Abstract.—Bighead Carp Hypophthalmichthys nobilis and Silver Carp H. molitrix are native in the Yangtze River and extremely important economically and culturally as food fishes; however, the two species have declined due to overfishing and anthropogenic modifications to hydrology and water quality. Bighead Carp and Silver Carp were imported to North America in the early 1970s, escaped confinement, and have now become undesirable and problematic invasive species. The two carps have become the most abundant fish species in many portions of their invaded range, which continues to expand. We compare the biology, status, and management of these species between their natal range in the Yangtze River and their invaded habitats of the Mississippi River basin.
