| 摘 要： | 目的]了解安康地区泥鳅的胚胎发育全过程。方法]用DOM和LHRH-A2对泥鳅进行催产,将所产卵子进行人工授精后所获的胚胎置于24～26℃、pH值7.0～7.5的淡水中培养,进行泥鳅的胚胎发育观察,详细描述从受精卵到初孵仔鱼期的27个发育时期的形态特征和发育时间。结果]泥鳅胚胎发育可划分为卵裂期、囊胚期、原肠胚期、神经胚期和器官形成期。在24～26℃、pH值7.0～7.5的淡水中,泥鳅胚胎从受精到孵化出膜历时30h45min。结论]为泥鳅的人工繁殖和遗传育种研究提供了重要的参考。

| Abstract: | Objective]Aim to know the whole process of embryonic development of loach. Method] DOM + LHRH-A2 was used to induce spawning of loach,then after fertilization,the embryos were cultured into freshwater water with temperature from 24 to 26 ℃ and pH from 7.0 to 7.5. The embryonic development of loach was observed and 27 concrete morphological characteristics and development time of loach from fertilized egg to newly hatched larval period were described in detail. Result] The embryonic development of loach could be divided into cleavage stage,blastocyst stage,gastrula stage,neurula stage and organogenesis stage.The loach embryo from fertilized egg to out membrane period was 30 h 45 min in fresh water from 24 to 26 ℃ and pH from 7.0 to 7.5. Conclusion] It provided important reference for studying artificial propagation and genetic breeding of loach. |
