The development of proliferation and culture of marine fishes is the fundamental measure and strategy for the exploitation and sustainable development of marine fishery resources. Therefore, developing and heightening the techniques of proliferation and culture of marine fishes, particularly the advanced techniques of artificial propagation and larval rearing as the bases of proliferation and culture, represent an important research field of marine biotechnology. Recently, in the aspects of induction of gonadal maturation and egg quality improvement, ovulation and spawning, artificial advanced sexual mature and sex reversal, regulation of continual mature and spawning for year - round, improvement of larval rearing and enhance their survival and growth rates, as well as production of a variety of hormones and neuropeptides for promoting reproduction and growth by gene engineering techniques were achieved major advancements, and displayed fine prospects for the productive application.
