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 aquatic invasive species challenges.
The goal of this project is to evaluate CO2 as a control chemical to address aquatic invasive species needs identified by natural resource managers across the United States. Studies are conducted in laboratories, outdoor ponds, and field settings to collect data on toxicity, behavioral manipulation, and other beneficial endpoints that support aquatic invasive species control. Examples of studies range from behavioral deterrence of CO2 with invasive round goby (Neogobius melanostomus), lethality of CO2 with invasive zebra mussels (Dreissena polymorpha), and behavioral stimulation of invasive red swamp crayfish (Procambarus clarkii).

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 as an Invasive Carp Lethal Control
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...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.
