In Indoor Aquaculture, we implement many treatments like ultraviolet sterilization, ozonation, and oxygen injection to maintain optimal water quality. Even though there are many of the environmental drawbacks, there are many benefits like fish escapes, water usage, and the introduction of pollutants. The many latest techniques the improves of efficient fish growth by providing optimum water quality.
