草、鲢、鳙亲鱼早繁殖,早出苗、早培育、早投放好处很多:鱼苗培育时间长,生长速度快,水体中敌害生物少,鱼苗成活率高,要使草、鲢、鳙鱼提前产卵出苗,应从促进性腺早成熟着手,加强亲鱼的产后培育和夏、秋季培育。同时,从以下三个方面加强亲鱼的春季培育,争取提前15—30天催产鱼苗。 Grass, silver carp and broodstock early breeding, early emergence, early breeding, and early release have many advantages: long fry breeding, fast growth, less harmful organisms in the water, fry survival rate is high, to make grass, silver carp, bighead carp advance Spawning emergence, should start from the promotion of gonadal maturation to strengthen the broodstock postpartum breeding and summer and autumn cultivation. At the same time, we should strengthen the cultivation of broodstock in the following three aspects and try to fish fry 15-30 days in advance.
