Abstract:Fishes germplasm resources provide essential material foundation for sustainable, healthy and stable aquaculture. The new strain or species with the good quality, high nutrient and efficiency as well as high yield are the keys to promote the sustainable development of aquaculture. Fish growth rate is an important index for evaluating the breeding values, which is also one of the important breeding traits in practice. Yet the fish breeding foundation is poor, the improvement theoretical basis and technology innovation has been plagued the fish breeding work. In order to provide theoretical basis and guidance to improve the growth traits and regulation, effects of internal factors (genetic, physiology) and external factors (food, temperature, oxygen and species relationships, etc.) on growth were discussed, based on the strategy of fish growth traits regulation and improvement were reviewed.
