Abstract: An industrial aquaculture system, a kind of aquaculture practiced industrial technology, is characterized by high density, saving water resources and less pollution. The efficient and reasonable increase in dissolved oxygen level can effectively improve the efficiency of facilities, equipment, and reduce the costs of production, and thus is one of the key technologies in the industrial aquacul- ture system. The present paper describes some characteristics of ventilative equipment and technology and the efficiency of aeration. Meanwhile, some problems of the oxygenation technology are analyzed and the trend of aeration application and innovative technolo- gy is discussed to provide information on increase in dissolved oxygen level in an industrial aquaculture system for further study.

Key words: industralization, aquaculture, oxygenation
