摘要/Abstract

摘要： 采用HCG、S-Gn RH-A和DOM混合注射催产技术以及人工授精技术,催产细鳞鱼亲鱼400尾（雌雄比为3∶2）,获得总卵数58.4万粒,催产率达到86.25%,受精率达到97.32%。通过购置、建设平列槽、温室、专用培育池等设施渔业进行苗种培育,孵化率达到91.13%,苗种养殖成活率达到89.37%,培育出细鳞鱼苗种39.2万尾。结果认为：采用当年孵化的苗种在网围中养殖、越冬后再放流模式可有效提高放流苗种存活率,转化增殖效果明显,是大型水域捕食性鱼类增殖和低值野杂鱼转化增值的有效途径。

Abstract: Using the HCG, S-Gn RH-A and DOM mixed injection of oxytocin and artificial insemination technology, induced spawning oxytocin 400（male and female ratio is 3∶2）, 584 thousand eggs, oxytocin rate of 86.25%, fertilization rate reached97.32%. Through the purchase, construction of parallel trough, greenhouse, special cultivating facilities for seedling cultivation, hatching rate of 91.13%, raising seedling survival rate reached 89.37%, Brachymystax lenok seedlings were developed to 392 000. The results showed that the incubation of seedling breeding in net confining and discharge model after wintering can effectively improve seedling survival rate, and conversion of proliferation effect was obvious, it is a an effective means for proliferating large predatory fish and low-value miscellaneous fish.
