摘要
罗非鱼性别主要受遗传和环境因素共同制约决定。遗传因素是性别决定的基础,而温度性别决定只在临界敏感期起作用。罗非鱼性别控制的主要手段有激素诱导、种间杂交和激素诱导相结合及人工诱导雌核发育。
Sexuality of tilapia is determined by gennetic and environmental factors.Germetic components are still the basis of sex determination,and temperature sex determination only takes action on critical sensitive period.The primary measures of sex control in tilapia include:hormonal induce,interspecific hybridization combining with hormonal induce and artificial indueed gynogenesis.
