Abstract: Types and levels of nutrients in feed not only affect gonad development, fecundity, gamete production, fertilization rate, hatching rate and embryonic development of aquatic animals, but also affect the quality and survival rate of their larvae. In the course of breeding, the common methods to promote reproduction mainly include physical heating and cooling, water stimulation, dry stimulation, and removal of eyestalks. In recent years, it has become the focus on scientific research and commerce to control the reproductive capacity of aquatic organisms by changing the types and levels of nutrients in feedstuffs. In this paper, the application status of common nutrients in aquaculture is reviewed, and the effects of different nutrients on the reproductive performance of aquatic animals are introduced. Many studies have shown that nutrients such as protein, fat, vitamins, minerals and sugars can significantly improve the growth performance and reproductive capacity of aquatic animals, but some contradictory results have also been reported. These results seem to depend on differences in the type, source, content, and experimental conditions of cultured aquatic animals. The purpose of this review is to discuss the effects of different sources and levels of nutrients on the reproductive capacity of aquatic animals and their mechanisms, so as to provide scientific basis for the promotion of aquaculture.
