This paper objectively analyzed the main problems existing in the highspeed development of China＇s aquatic product industry by empirical analysis. For example, the situation of quality and safety of aquatic products is serious now; the basic conditions of aquaculture lag behind the production development; aquatic industry is still in a low level of development and organization; and the quality and safety of aquatic products is the most main problem. This paper also revealed that fish would be the main source of animal-derived food, and the demand of characteristic aquatic products would continuously go up. Aquatic processing has initially formed a standard system. It drew a conclusion that it would be a good opportunity for China＇s aquatic processing industry in the future展开更多
