摘要:

在鱼类繁殖过程中,促性腺激素释放激素GnRH(Gonadotropin releasing hormone)作为脊椎动物“下丘脑-垂体-性腺(HPG)轴”的关键因子,对性腺发育和性激素分泌具有重要调控作用,其生理功能对鱼类繁殖活动的成功至关重要。本综述总结了近年来国内外关于GnRH在鱼类繁殖中的研究进展,包括GnRH的结构分类、主要功能、作用机制及其类似物在鱼类繁殖中的应用。通过分析GnRH在调控鱼类性腺发育、性激素分泌及诱导排卵等方面的作用,揭示了其在鱼类繁殖中的核心地位。本综述旨在为深入解析鱼类生殖机制提供理论依据,同时为提高鱼类繁殖效率、开发GnRH相关繁殖调控技术提供参考,为进一步研究GnRH在鱼类繁殖中的应用潜力奠定基础。

Abstract:

In the process of fish reproduction, GnRH (Gonadotropin releasing hormone), as a key factor in the hypothalamus-pituitary-gonad (HPG) axis of vertebrates, plays a crucial regulatory role in gonadal development and sex hormone secretion. Its physiological functions are essential for the success of fish reproductive activities. This paper reviews recent domestic and international research progress on GnRH in fish reproduction, including the structural classification, main functions, mechanisms of action, and applications of GnRH analogs in fish reproduction. By analyzing the roles of GnRH in regulating fish gonadal development, sex hormone secretion, and ovulation induction, the core position of GnRH in fish reproduction is revealed. This review aims to provide a theoretical basis for in-depth understanding of fish reproductive mechanisms, while offering references for improving fish reproductive efficiency and developing GnRH-related reproductive regulation technologies. It also lays the foundation for further research on the application potential of GnRH in fish reproduction.
