摘　　要：为了摸索不同孵化方式对黄河鲤受精率和孵化率的影响,本研究以黄河鲤为亲本,设置了孵化桶孵化、精卵混合加水30s后布网孵化以及精卵混合后直接布网孵化等3种孵化方式,每组设3个平行实验。在鱼苗孵化阶段,每天8:00、12:00、18:00定时测水温,并更换1/3水体。结果显示三种孵化方式间的受精率和孵化率差异不显著(p>0.05),在生产过程中可以根据实际条件来选择不同的孵化方式,而不用考虑其对受精率和孵化率的影响。In order to explore the effects of different hatching methods on the fertilization rate and hatching rate of theCyprinus carpio.We set up 3 experimental groups as hatching in hatching-bucket,hatching in net after mixing sperm,eggs and water 30s later,hatching in net after mixing sperm and eggs.These groups were divided into three parallel groups respectively.In the period of hatching,we measured the water temperature at 8:00,12:00 and 18:00 every dayand 1/3 of the water was replaced everyday.The results showed that the three hatching methods had no significant effect on the fertilization rate and hatching rate of the Cyprinus carpio (p>0.05).Different hatching modes could be selected according to the actual conditions during the production process,without considering the influence on the fertilization rate and hatehing rate.
