Asian Carp Control: Carbon Dioxide

Management agencies have identified key pinch-points where there is a need to block Asian carp passage. Recent studies have shown that carbon dioxide (CO2) can be an effective behavioral deterrent for Asian carps and could be used independently or in combination with other deterrents to reduce the risk of migration into new areas. Installation of a deterrent at these management locations requires extensive architecture and engineering to understand the feasibility of CO2 as a fish deterrent under various conditions and scales.

The goal of this project is to design and test a large-scale CO2 infusion system to determine its feasibility at relevant management scales. Prototypes have been designed to minimize potential interference with navigation, while simultaneously optimizing CO2 gas-transfer to maximize efficiency. Studies are conducted in flumes, ponds and field settings (e.g. navigational locks) to collected operational data related to the engineering and costs of a CO2 deterrent system.
