发展海洋鱼类的增殖和养殖是海洋鱼类资源的合理开发利用与持续性发展的根本措施和策略。因此，发展和提高海洋鱼类的增殖养殖技术，特别是做为增养殖基础的人工繁殖和苗种培育新技术，是海洋生物技术的一个重要研究领域。近年来在诱导海洋鱼类性腺发育成熟和改善卵子质量、排卵与产卵、提早性成熟和性别 转换，调控海洋养殖鱼类在全年都能性腺发育成熟和产卵、改善幼苗培育与提高成活率和生长率以及采用基因 工程技术生产各种促进鱼类生殖与生长的激素与神经肽等方面都取得明显进展，并且显示良好的生产应用前景。

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.
