摘要
在硬骨鱼类中,一些种类因为雌雄二态性导致养殖效益差异明显.为了提高水产养殖效益,单性养殖是雌雄二态性鱼类育种的目标之一.性逆转作为通过性别控制育种实现单性养殖的有效手段之一,始终是硬骨鱼类繁殖和育种研究的热点.本文从已知硬骨鱼类天然性逆转现象、性逆转方法、性逆转作用机理以及目前在鱼类育种中的应用等方面进行阐述,为选育优质新品种、加快提高硬骨鱼类的养殖效益提供分子育种的理论参考.
Abstract
In teleosts fish,some species have significant differences in breeding benefits due to male and female dimorphism.In order to improve the efficiency of aquaculture,monoculture is one of the goals of these fish breeding.Sex reversal,as one of the effective means to achieve unisexual breeding through sex-controlled breeding,has always been a hot topic in teleosts fish reproduction and breeding research.In this paper,the known teleosts fish natural sex reversal phenomenon,sex reversal method,sex reversal mechanism and current application in teleosts fish breeding are described,which provides a theoretical reference for molecular breeding for new varieties of high quality and accelerating the improvement of fish breeding efficiency.
