近年来,我省广大农村大搞鲤鱼繁殖,但获苗率很低,为此,谈淡提高鲤鱼孵化率的方法: 1、清整孵化池:以小型为佳,面积1—2亩,要求水源方便,水深0.6—1米,水质清洁,要先用生石灰彻底清整鱼池,杀灭敌害。注水要经纱窗过滤。孵化过程中检查受精率和估算孵化率,防止孵出的鱼苗密度过大,以免因活饵料不足等原因引起大量死亡。不同时间产的卵不宜放在同一池中孵化,防止以强欺弱或大苗残杀小苗。
In recent years, the majority of rural areas in our province engage in carp breeding, but the seedling rate is very low, for this reason, talk about ways to improve the hatching rate of carp: 1, to clean the hatchery: small is better, an area of 1-2 acres, Convenient water, water depth of 0.6-1 meters, clean water, you must first clear the fish pond with quicklime to kill enemy damage. Water to filter through the screen. Check the fertilization rate during hatching and estimate the hatching rate to prevent the density of hatched fry is too large, so as to avoid a large number of deaths due to lack of live feed and other reasons. Different time eggs should not be hatched in the same pool to prevent bullying or bulimia seedlings.
