<em>Abstract</em>.—Bighead Carp <em>Hypophthalmichthys nobilis </em>and Silver Carp <em>H. molitrix </em>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.

Carbon dioxide (CO2) in water has been explored for use as an invasive species deterrent system. To date, studies have not determined CO2 avoidance by fish in flowing water, and this is a necessary step before an operational deterrent system can be implemented. The objective of the study was to define how flowing water influences the response of bighead carp (Hypophthalmichthys nobilis) to continuous plugs of CO2. A choice experiment by which CO2 was injected into channels of an annular flowing water flume was completed. In trials when CO2 was injected into the inner vein, fish spent less time in the vein when compared with control conditions. An increased amount of lateral movements and reduced performance were also observed when fish were exposed to elevated CO2. The study demonstrates that bighead carp in flowing water enriched with CO2 move away, a finding consistent with static water experiments.
