Abstract
The Japanese eel (Anguillajaponica) is one of the important aquaculture fish in China. To facilitate feed manufacture and the development of eel industry, it is critical to study nutritional requirements of this species. In this article, we provide up-to-date information regarding protein, lipid, vitamin and mineral requirements of the Japanese eel, and summarize studies on both replacements of scarce natural nutrients with more sustainable alternatives (e.g., plant proteins) and feed additive functions. To bridge the current major research gaps in knowledge of nutrition needs, we suggest that, in the future, special attention should be paid on comprehensive understanding of nutrients required at different growth stages of the Japanese eel, particularly in larval stage. Moreover, nutritional requirement database for the Japanese eel should be established. Researches on functions of multi-additives and interactions between different additives should be enhanced; mechanisms underlying synergistic and antagonistic interactions should be understood in depth. To sum up, the information and suggestions in this article will be helpful for better understanding of the nutritional requirements of the Japanese eel, for formulating nutritionally balanced feed, and for facilitating the sustainable development of eel aquaculture industry.
