Intensive fish farming systems are typically established in regions with abundant and high-quality flow-through water. In such systems, the oxygen requirements for fish and aquatic products are guaranteed by the incoming water flow. This implies that the carrying capacity of fish or aquatic products depends on the water flow rate. However, the water flow rate cannot be increased indefinitely due to technical, economic, and physiological constraints.
By applying pure oxygen, the oxygen supply no longer limits the carrying capacity of fish and aquatic products in the system. Furthermore, the oxygen supply can be regulated, enhancing operational safety. A significant advantage of using pure oxygen is its high mass transfer rate between oxygen and water.
To minimize oxygen consumption, oxygen-dissolving devices are necessary to ensure optimal oxygen absorption by water. One method is bubbling aeration, where oxygen gas comes into contact with water by breaking into bubbles. The rate of oxygen diffusion primarily depends on the water layer depth, the travel distance of bubbles within the water body, and the oxygen supply rate. Reducing bubble size can improve efficiency, as this increases contact time and surface area.
The CanGas energy-saving oxygen generation system, combined with professional solutions for aquaculture, is the best choice for achieving on-site oxygen availability, thereby sustainably advancing aquaculture operations in the long term.
