Carbon Dioxide as an Invasive Carp Behavioral Deterrent
Introduction of invasive carps into public waters of the United States has resulted in a large effort to limit dispersal beyond the Mississippi River watershed. Navigation structures positioned throughout most major rivers are potential pinch-points to block further range expansion into new areas. Carbon dioxide (CO2) is being evaluated as non-physical fish deterrent that could reduce fish passage through navigational locks while supporting continued use of the waterway by commercial and recreational navigation.
Invasive Carp Control: Carbon Dioxide
The goal of this project is to characterize fish behavior when exposed to a CO2. More specifically, we are studying fish behavior to determine if CO2 could be applied to deter invasive carps from locations (e.g. lock chambers) where they are at risk to move upstream. Studies are conducted in laboratory, outdoor pond, and field settings using acoustic telemetry, hydroacoustic sonar, and underwater cameras to monitor fish behavior. Results are intended to inform natural resource decisions related to the integration of CO2 as a new control tool to better manage invasive carps.
