中文摘要：罗非鱼全雄养殖可有效控制繁殖、提高养殖效率,遗传全雄罗非鱼(Genetically male tilapia,GMT)技术是性别控制的高效手段,但GMT技术培育的鱼苗雄性率不稳定。基因组学和基因编辑等技术已广泛应用于罗非鱼研究,极大地促进了罗非鱼性别决定与分化基础理论研究。分析导致XY个体性别逆转的可能因素,提出将来GMT技术研究的关键问题,探讨现代基因编辑技术在罗非鱼性别控制育种中可能应用。

外文摘要：Tilapia is a worldwide aquaculture fish.Since the male is growing faster than the female,all-male culture is preferable in tilapia aquaculture,to avoid unwanted reproduction before harvest and increase culture efficiency.Genetically male tilapia(GMT)technology is an efficient method of sex control,which has a history of more than 40 years.This paper reviews the progress and existing problems of GMT technology.In recent years,genomics and gene editing techniques have been widely used in tilapia research,which has greatly promoted the fundamental theoretical research of tilapia sex determination and differentiation.However,sex differetiation of tilapia is affected by many genetic and environmental factors,and GMT technology is difficult to guarantee the male rate in commercial strains limiting the large-scale application of this technology.Analyzing the reason for the existence of XY females will promote the development of GMT technology.The improvement of GMT technology will boost the aquaculture industry to develop healthily and provide references for sex control breeding of other aquatic animals.
