Abstract:

We were the first to be defined and studied the aquatic animal eco-nutrition and feed with nutrition emission reduction in order to reduce the negative effects of water environment and health, those caused by nutrition, feed and feeding. The researches systematically regulated internal and external environment of aquatic animals, guided by new theory and method of eco-nutrition and also adopted modern nutrition, biotechnology, processing technology, feeding strategy, etc. We obtained 6 important achievements after 10 years experiment study. 1) �??Rhomb Characteristics�?� was firstly named and defined that the relationship between WGR and NH4+-N was typical of protein eco-nutrition and the change curve looked like a rhomb. 2) Achieved eco-nutrition requirements of main nutrients for some marine fish in recirculation aquaculture system (RAS), providing important parameters for developing ecological and valuable compound feed. 3) Preliminary ascertained the effects of diet protein, satiety degree on growth, N excretion, digestion and immunity of Cynoglossus semilaevis G. 4) Produced initial success on association study between eco-nutrition and molecule nutrition. 5) The development on compound feed with N and P emission reduction for flatfish made a breakthrough and the new products applied rapidly. 6) Scored important result on study of feeding strategy and intake model. In conclusion, the results provided theoretical basis and applicable technology for the goal of sustainable aquaculture that is the balance and harmonious development among suitable nutrients, stability environment, healthy growth, excellent products and cheap cost.
