摘　　要：试验设计3个温度16．0～17．0℃、18．5～20．5℃和22．0～24．0℃，采用3种催产剂组合催产，对花[鱼骨]人繁子代亲鱼进行催产试验。试验表明：用HCG1000IU／kg＋LRH—A21．2μg／kg、DOM5．0mg／kg＋LRH—A21．2μg／kg、PG3．0mg／kg＋LRH—A21．0μg／kg组合均能成功催产人繁子代花[鱼骨]亲鱼。其中，在18．5—20.5℃和22．0—24．0℃催产中，DOM5．0mg／kg＋LRH-A21．2μg/kg具有较短的催产时间和较高的催产率、受精率。人繁子代亲鱼在池塘培育条件下完全可以进行人工催产，花[鱼骨]可以像“四大家鱼”一样进行全人工繁殖。Artificial propagated Hemibarbus maculatus Bleeker was induced to spawn at three temperature ranges, 16.0 - 17.0 ℃, 18.5 - 20.5 ℃ and 22.0 - 24.0 ℃, by injection of DOM ＋ LRH-A2, HCG ＋ LRH-A2, or PG ＋ LRH-A2. The results showed that the three injection improved the spawn and hatch of artificial Hemibarbus maculatus , especially at 18.5 - 20.5 ℃ and 22.0 - 24.0 ℃. Under the water temperature of 18.5 - 20. 5 ℃ and 22.0 - 24.0 ℃, DOM ＋ LRH-A2 was effective to the fish with short effect time and high spawning rate and fertilization rate, indicating that Hemibarbus maculatus can be artificially induced to spawn in the same method as that used in Chinese carps.
