罗非鱼在养殖中具有食性广、抗病力强,生长快、产量高等特点,单养亩产可过千斤,混养也达200—400斤。我国南方各省基本上已推广养殖。由于其繁殖力太强,若不加以控制,群体的密度就会超过饵料和水体的生态条件所可能允许的范围。这样的结果,个体的生长速度受到障碍,商品量下降,不利于生产的发展。通过投喂雄性激素,可以使雌体转变为雄
Tilapia in feeding with wide feeding, disease resistance, fast growth, high yield, single-acre per kilogram can be over 1000 kg, polyculture up to 200-400 pounds. Basically, the southern provinces of our country have promoted breeding. Because of their fertility, if not controlled, the density of the population will exceed the allowable range of ecological conditions of feed and water. As a result, the growth rate of the individual is impaired, the quantity of the product declines, which is unfavorable to the development of production. By feeding androgens, the female body can be turned into a male
