秋冬季节,亲鱼性腺正处于发育早期,这个阶段亲鱼培育的好坏,将直接关系到亲鱼怀卵量的多少,同时决定着翌年春季亲鱼人工繁殖的成败。因此,必须重视亲鱼的秋冬季节培育工作。1、看水施肥 鲢、鳙鱼是以浮游生物为食,通过施肥促使浮游生物的大量繁殖,如果鲢、鳙鱼饵料充足,性腺发育就好。因此,看水
In autumn and winter, the gonads of the broodstock are in the early stage of development. The quality of broodstock breeding at this stage will be directly related to the amount of eggs laid by the broodstock. At the same time, the success or failure of artificial broodstock breeding in the spring of next year will be determined. Therefore, we must attach importance to broodstock cultivation work in autumn and winter. 1, to see water fertilizer silver carp, mackerel is plankton for food, fertilization to promote the large number of plankton breeding, if silver carp, mackerel feed enough, gonadal development is good. So look at the water
