三种接卵方法对鲤鱼产孵效果的比较

本通过漂浮巢、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。

The comparison of three different methods effects on common carp hatching

We have tested three different methods on the effects of common carp hatching by using drift nest,bottomnest,hatching meeting ratio,impregnation ratio,seedeing living ratio and living ratio.To the egg meeting ratio,result of using hatching tank is the best,and bottom nest is better than drift nest.To the impregnation,bottom nest is the best,the second is drift nest,hatching tank is the last.To the seeding living ratio,hatching taml os tje best,the metal bottom nest is better than drift nest.To the living ratio,hatching tank is better than bottom nest,and drift nest is the third.We described the advantages and disadvantages of the three methods in common carp hatching,and pointed out that the produce unit should apply hatching tank or bottom nest for their better results,but should according to the factual conditions.
