本文通过漂浮巢、底铺巢、孵化桶三种不同方法鲤鱼产孵效果的试验 ,进行了接卵率、受精率、出苗率、成活率的比较。得出接卵率 :孵化桶 >底铺巢 >漂浮巢 ;受精率 :底铺巢 >漂浮巢 >孵化桶 ;出苗率 :孵化桶 >底铺巢 >漂浮巢 ;成活率 :孵化桶 >底铺巢 >漂浮巢。并综合评述了三种不同方法在鲤鱼产孵中的优缺点 ,提出生产单位根据实际条件 ,采用孵化桶或底铺巢效果较好 In this paper, we compared the hatching rate of carp with three different methods of floating nest, bottom nesting and hatching barrel, and then compared egg yield, fertilization rate, germination rate and survival rate. Hatching bucket> bottom nest> floating nest; fertilization rate: bottom nesting> floating nest> hatching barrel; emergence rate: hatching barrel> bottom nesting> floating nest; survival rate: hatching barrel> bottom shop Nest> Floating nest. The advantages and disadvantages of three different methods in hatchery of common carp were comprehensively reviewed. It was suggested that the hatching barrel or bottom nesting should be used according to the practical conditions
