在草鱼的人工繁殖中，使用了三种不同的催产剂ＬＲＨ－Ａ３、ＬＲＨ－Ａ３＋ＲＥＳ、ＬＲＨ－Ａ２＋ＲＥＳ，结果表明：使用ＬＲＨ－Ａ３＋ＲＥＳ和ＬＲＨ－Ａ２＋ＲＥＳ组的催产率分别高出单独使用ＬＲＨ－Ａ３组的３７．５％和３８．９％，受精率分别比单独使用ＬＲＨ－Ａ３组高出２０．１％和３０．１％。
LRH-A3, LRH-A3 + RES and LRH-A2 + RES were used in artificial breeding of grass carp. The results showed that the rates of oxytocin production in LRH-A3 + RES and LRH-A2 + RES groups were higher than that of LRH-A3 37.5% and 38.9% of the group, respectively. The fertilization rate was 20.1% and 30.1% higher than the LRH-A3 alone group.
