Swimming performance of a freshwater fish during exposure to high carbon dioxide.

Deterring the spread of invasive fishes is a challenge for managers, and bigheaded carp (including bighead and silver carp, Hypophthalmichthys spp.) are invasive fish that have spread throughout large portions of the Mississippi River basin and threaten to invade the Great Lakes' ecosystem. Studies have shown that elevated levels of carbon dioxide gas (CO) have the ability to act as a nonphysical fish barrier, but little work has been done on the efficacy of CO to deter fish movement in flowing water.
