Invasive Carp Control: Carbon Dioxide
Management agencies often rely on commercial harvest for invasive carp population control. Piscicides, or fish toxicants, are an alternative method that could supplement Integrated Pest Management plans to kill and remove large quantities of invasive carps in a relatively short period of time. This non-selective removal strategy could greatly improve removal efficiency, particularly where high abundances of invasive carps are present.
The goal of this project is to determine the efficacy of carbon dioxide (CO2) as an under-ice lethal control. Ice cover provides a temporary boundary between water and the atmosphere which is beneficial to hold CO2 in solution and sustain a lethal exposure. Studies have been conducted in laboratory and pond settings to quantify lethal concentrations across species and life stages. Results are intended to inform natural resource management decisions regarding the potential utility of CO2 for invasive carp population control.

Registration of Carbon Dioxide–Carp
Invasive Carp Control: Carbon Dioxide Registration of new fishery chemicals is critical to facilitate field research and give resource managers the ability to incorporate chemical controls as part of their Integrated Pest Management plans. In April 2019, the U.S. Geological Survey (USGS) and U.S. Fish and Wildlife Service (USFWS) obtained a Section 3 registration from the U.S. Environmental...Effects of Carbon Dioxide on Non-Target Organisms
Invasive Carp Control: Carbon Dioxide Chemical controls are a vital component of many effective Integrated Pest Management plans. Carbon dioxide (CO2) is being evaluated as a new fishery chemical for invasive carps as a general toxicant or behavioral deterrent. Administration of non-selective chemicals, such as CO2, into public waters could pose a risk to non-target organisms (e.g. native mussels...Carbon Dioxide for General Aquatic Invasive Species Control
Invasive Carp Control: Carbon Dioxide Carbon dioxide (CO2) is being evaluated as a new fishery chemical for general aquatic invasive species control. Most research has focused on its effectiveness as a behavioral deterrent and lethal control or invasive carps. However, because CO2 is generally non-selective, there is potential for this new control chemical to be applied across a wide range of...Engineering and Testing of Carbon Dioxide Infusion Systems
Invasive Carp Control: Carbon Dioxide Management agencies have identified key pinch-points where there is a need to block invasive carp passage. Recent studies have shown that carbon dioxide (CO2) can be an effective behavioral deterrent for invasive carps and could be used independently or in combination with other deterrents to reduce the risk of migration into new areas. Installation of a...Carbon Dioxide as an Invasive Carp Behavioral Deterrent
Invasive Carp Control: Carbon Dioxide 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. Navigational 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 fish deterrent to... - Publications
