众所周知,影响罗非鱼养殖的主要问题是无控制的繁殖,从而妨碍了种群的生长。解决这个问题的办法之一是全雄性养殖(单性养殖),单性养殖是通过杂交和在性腺分化时鉴别雌雄鱼苗。然而这些方法产生的效果并不完全令人满意,因为要得到用于杂交育种的纯色亲鱼群体是困难的,以手工分开雌雄鱼苗也很困难。 It is well-known that the main problem affecting tilapia farming is uncontrolled reproduction, which hinders the growth of the population. One solution to this problem is all-male farming (monoculture), which is the identification of both male and female fry through crossing and during gonadal differentiation. However, the effects of these methods are not entirely satisfactory, as it is difficult to obtain a population of solid color broodstock for crossbreeding, and it is also difficult to separate the male and female fry by hand.
