The importance of dissolved oxygen in aquaculture

If the amount of dissolved oxygen (DO) in the pond is too low, the shrimp will eat less and there will be more left over food. This will affect other parameters of water quality, and if the water quality drops the shrimp will get weak and more susceptible to bacterial infection. Such conditions lead to low survival rates. When the DO of the water is low, the shrimp’s growth rate is slow and the feed conversion ratio (FCR) is very high. It takes longer to raise a batch of shrimp than when the DO is sufficient.

Farms that are successful in keeping the DO at no less than 4 ppm even in the morning are usually very successful, with good growth rates, a high survival rate and a low FCR. When the DO is maintained at at least 4 ppm, there is seldom a problem with white feces disease or bacterial infections. In contrast, on farms where the DO drops below 4 ppm at night, the shrimp will grow slowly during the culture period and white feces disease is very common.

Maintain healthier ponds, increase stocking densities and generate higher yield with optimum oxygen transfer. Maintaining the proper level of oxygen dispersion in your systems is critical to the success of your operation – and the life of your fish.

With increased mixing and dispersion through fine bubble aeration, our O2-TURBINE®, O2-JETER® Aerators, NANO TUBE® Tuing can help you maintain optimum oxygen transfer levels while maintaining a consistent temperature throughout the entire system to meet higher aquaculture production goals.
