This paper reviews the research in nutrition and feed development in aquaculture animals in recent years, and analyzes the problem and future development of feed industry. In past 10 years, great advances have been achieved in aquaculture animal nutrient requirements, feeding, larval feed, broodstock nutrition, additives etc. But there are still some problems regarding aquafeed including high feed conversion ratio, high environmental discharge, high feed cost and unstable profit. In the near future, the research and development of aquaculture nutrition and feed should focus on "high efficiency, safety, economic and environmental neutral". New concepts from ecology and genomics technologies should be applied in the study on molecular mechanism of nutrition and metabolism, nutrient requirements and accurate feed and feeding, feed quality control and processing, animal quality regulation, etc. The government should provide more opportunities for cooperation between scientists from different areas and long term support.
