Both situations present the problem of maximizing carbon dioxide removal from the water column and venting it to the atmosphere at minimal cost. Current intensive aquaculture techniques have exacerbated potential carbon dioxide problems due to common usage of pure oxygen absorption equipment. Such systems may not provide adequate gas exchange for stripping of carbon dioxide to prevent carbon dioxide accumulation to toxic levels. Additionally, pure oxygen absorption units support higher fish densities, which also increase the total carbon dioxide production within the system and increase the potential for carbon dioxide problems. Carbon Dioxide Control version 2.1 is based on mathematical models of carbon dioxide control strategies and provides for economic and feasibility comparisons between all options.
