摘　　要：于2015年4月在四川省凉山科华水生态工程有限公司水产良种场使用LRH-A2+DOM分2批对来自黄河水系的24尾(以雌鱼计)野生花斑裸鲤亲鱼进行人工催产。雌鱼在挤卵前死亡5尾,1尾未产卵,平均催产率为75.5%;18尾雌鱼共产卵14.3万粒,受精卵13.1万粒,受精率为91.6%;获初孵仔鱼10.2万尾,孵化率77.9%。研究结果表明,在非产区进行花斑裸人工繁殖是可行的。A total of 24 wild Gymnocypris eckloni Herzenstein（females） from the Yellow River area were used as parent fish to perform the artificial propagation experiment by injection of LRH-A2＋DOM. This experiment was carried out in high quality fish farm of Liangshan Kehua Water Ecological Co., Ltd. in April 2015. Five female fishes died before laying eggs and one didn′t lay eggs, and the average induced spawning rate was 75.5%; A total of 143 000 eggs were obtained from 18 female fishes,while only131 000 were fertilized with the fertilization rate of 91.6%; A total of 102 000 newly hatched larvae were gained with the hatching rate of 77.9%. It is indicated that artificial propagation Gymnocypris eckloni Herzenstein is feasible in the non-growing district.
