摘　　要：为比较孵化方式对泥鳅孵化效果的影响,试验采用4mg DOM＋3μg LHRH-A2对泥鳅进行催产,将所产卵子进行人工授精后,采用西北农林科技大学安康水产试验示范站自制溢水式孵化桶与水泥池置入40目绢纱布网箱两种方法对泥鳅受精卵进行去巢流水式孵化和鱼巢附卵孵化。在pH7.0~7.5、水温24~26℃的条件下,以孵化时间和孵化率探讨两种孵化方式对泥鳅孵化的影响。结果去巢流水孵化的孵化时间和孵化率为（30.52±0.89）h、（92.25±0.84）%;鱼巢附卵孵化的孵化时间和孵化率为：（38.56±1.04）h（、88.97±0.78）%。表明去巢流水孵化显著优于鱼巢附卵孵化。In order to compare the effect of different hatching methods on loach hatching,the experiment adopted 4 MG DOM＋3 μg LHRH-A2 to hasten partrition of loach.After artificial fertilization to the eggs,the methods of hatching in flow water without nest hatching in egg collecter were used to hatch the eggs.With the conditions of pH 7.0~7.5 and water temperature of 24~26℃,the effect of loach hatching were discussed from the aspects of hatching time and hatching rate.The results showed that the hatching time and hatching rate for the methed of hatching in flow water without nest were（30.52±0.89） h and（92.25±0.84）%;and that of the method of hatching in ege collector were（38.56±1.04）h,and（88.97±0.78）%.The results revealed that the methed of hatching in flow water without nest is suprior to the method of hatching in egg collector.
