This study is based on industry information research on current industry situation,development trend in domestic and international.According to the result of industry information research,we gave some suggestions about the industry development of cold water fish in China.

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.

The effects of feeding regimes on growth and immune indices in juvenile sea cucumber（Apostichopus japonicus） with body weight of 0.745±0.3g fed the diet containing selenomethionine（0.5 mg/kg） were studied at water temperature ranging from 9℃ to 13℃ from March 10,2010,to May 9,2010 in a lab.Total of 150 individuals were selected,randomly stocked into tanks of each 50 cm ×40 cm ×30 cm at a rate of 10 individuals per tank,and fed the diet containing seleniomethionine once daily（Group 1）,once every 5 days（Group 2）,once every 10 days（Group 3）,once every 15 day（Group 4） and once daily for the diet without selenium（Group 5,as control group） with triplication for 60 days.The results showed that the sea cucumber fed the diets containing selenium had significantly higher survival than that in the control group（P 0.05）,even though they had no significant differences in the specific growth compared with the animals in the control group（P 0.05）.There were very significantly higher activities of superoxide dismutase（SOD）（78.34 U/ml） and glutathione（GSH）（2.87×10-5mol/L） in the Group 2 than those in the control group（P 0.05）.No significant difference in the concentration of GSH was found between Group 2 and Group 3,and Group 4（P 0.05）.Compared with the other groups,there were higher acid and alkaline phosphatase activities（2.42 U/ml,and 5.76 U/ml） in Group 1,without significant difference（P 0.05）.It is recommended that the sea cucumber be fed the diet containing seleniumomethionine every day for promotion of survival and immunity.

The developmental history of sturgeon aquaculture industry and cultural technological research in China were described by research practices of the authors and the relevant data,and developing tendency was introduced,particularly focusing on the aquaculture species,aquaculture areas,production manners,production and industry development trend.The proposals on the primary challenges of the industry development were discussed in the article.
