Mechanical aeration is by far the most common and effective means of increasing DO concentrations in aquaculture. Because of the high efficiency, easy installation, and slightly lower price, the impeller aerator market share was more than 80% in China. The power of Biofan is only tens of watts, but it can enable a wide range of pond water circulation. Through photosynthesis of aquatic plants, the DO concentration in surface water increases rapidly on sunny days, and it can make the whole pond water rich in oxygen. It is far more efficient than other mechanical aerators on clear days, but it cannot play the role of emergency aeration, especially on rainy days or at night. Therefore, it must be used with other mechanical aerators. To give full play to their respective advantages, Biofan and impeller aerator compound applications are adopted. The compound aeration mode saved about 30% of the electric energy compared with the single aeration mode.
