摘　　要：2014—2015年对野生小黄鱼在人工养殖条件下的繁育技术进行了相关试验研究,主要包括亲鱼的室内越冬、强化培育和人工催产技术。选取2000尾小黄鱼,体质量平均为67.24g,分别饲养于4m×8m×1.5m的越冬池,越冬池水温10~11℃,投喂少量配合饲料,进行亲鱼营养强化,亲鱼使用促黄体素释放激素A2和人绒毛膜促性腺激素催产。经52d营养强化,小黄鱼体质量增至88.30g,营养强化组的卵巢质量和性腺指数均显著高于对照组（P〈0.05）,表明通过投喂冰鲜饵料并添加维生素C和维生素E,可显著促进小黄鱼的性腺发育和成熟,提高其性腺指数和相对怀卵量;使用1.2μg/kg促黄体素释放激素A2搭配500IU/kg人绒毛膜促性腺激素对雌鱼进行催产,催产效果最佳,人工受精率和孵化率分别为23.35%和80.56%。The experiment was conducted to establish the technique of indoor overwintering, broodstock cultivation and spawning induction for small yellow croaker Pseudosciaena polyactis based on biological i- dentification from 2014 to 2015. The results showed that there were significantly higher ovary weight and gonado-somatic index （GSI） in the experimental group than those in the control group （P〈0.05）, indica- ting that the GSI and relative fecundity of small yellow croaker were enhanced by feeding high-protein diet with Vc and VE. The optimum fertilization rate of 23.35 % and hatching rate of 80.56%, were observed by injection of LHRH-A2and 500 IU/kg HCG at a dose of 1.2 μg/kg.
