摘要
在河南省首次对泥鳅进行了大规模人工繁殖试验,并对人工繁殖过程中不同催产剂对催产效果的影响和泥鳅胚胎发育过程作了探讨。试验结果表明,不同催产剂的效应时间和催产效果明显不同。在人工控制条件下,泥鳅性腺发育正常,催产率因催产剂不同而不同,使用LRH-A2和DOM混合催产和使用HCG和LRH-A2混合催产效果更明显,在水温21-24℃、盐度5‰的流水环境中,经25h左右仔鱼大量出膜,体长为3.5-4.8mm。
Based on an unprecedented large-scale artificial breeding experiment on loaches in Henan Province, this paper discusses the effects of different oxytocics on induced spawning and the process of embryonic development in the course of artificial breeding. The results show that different oxytocics have different reactive time and effects. Under controlled conditions, the gonad of loaches develops normally, but the induced spawning rate changes with the use of oxytocics： the effect of a mixture of progesterone-releasing hormone （LRH-A2） and maleic acid in Europe-（DOM） is better than that of HCG and LRH-A2. In an environment with running water temperature of 21-24 ℃, salinity of 5 ‰, a large number of larvae of loaches with body length of 3.5-4.8 mm will be spawned from membrane after 25 hours.
