| 摘 要： | 采用地欧酮(DOM)、绒毛膜促性腺激素(HCG)、促排卵素2号(LHRH-A2)3种不同药物对泥鳅进行催产试验,结果表明每尾泥鳅注射DOM 0.25 mg+LHRH-A2 3μg+HCG 150 IU为最佳催产激素配比,催产率达到85%。规模化泥鳅苗种培育阶段的开口饵料以蛋黄和浮游生物混合营养为佳,在透明度为50 cm的土池培育的泥鳅苗种成活率高、生长快。

| Abstract: | Three different drugs E European ketone （DOM）, human chorionic gonadotropin （HCG）, and LRH No. 2 （LHRH - A2） ] were used to conduct a parturition - hastening test for loach （ Misgurnus anguillicaudatus）. The results showed that injecting DOM O. 25 mg ＋ LHRH - A2 3 μg ＋ HCG 150 IU into one loach had the best parturition - hastening effect, and the parturition -hastening rate reached 85%. At large - scale loach fry rearing stage, the compound .of egg yolk and plankton was better initial bait for loach fry ; the loach fries reared in the earth pond with 50 - em - deep transparency had high survival rate and growth speed. |
