2012-2013年在浙江宁波市象山港湾苗种有限公司育苗场，以野捕岱衢洋大黄鱼驯养繁育的后代性成熟鱼2260尾为亲本，通过注射促黄体释放激素类似物（LRH-A3）催产，共获得受精卵1.58×108粒，在水温23～24℃、盐度22～24、pH 8.0～8.3、光照1000～1500 lx条件下，共孵化出仔鱼苗1.13×108尾。鱼苗培育以轮虫、卤虫无节幼体及桡足类为系列饵料，在水温22～24℃、盐度22～24、pH 7.9～8.3、光照1000～3000 lx条件下，经过42～47 d得到全长2.5～3.0 cm鱼苗3.21×107尾，成活率为28.4%。育苗过程中应注意亲鱼的培育、饵料系列的转换与搭配、水质的管理以及密度的控制等技术关键。本试验结果为今后岱衢洋大黄鱼大规模人工育苗技术推广提供参考。

In February-March, 2012 and 2013 respectively, 2 260 offspring of wild Pseudosciaena crocea of Daiqu species in Gangwan Aquatic Fingerlings Limited Company of Xiangshan used as parents, produced 1.58×108 eggs by injection of LRH-A3. 1.13×108 youths were hatched from these eggs under the condition of water temperature 23-24 ℃, water salinity 22-24, pH 8.0-8.3 and the light intension 1 000-1 500 lx. 3.21 × 107 fries of P. crocea with 2.5-3.0 cm total length were produced under the water temperature of 22-24 ℃, wa-ter salinity of 22-24, pH of 7.9-8.3 and the light intension of 1 000-3 000 lx in 42-47 days, fed with rotifer, artemia and copepoda. The breeding survival rate was 28.4%. Broodstock cultivation, conversion and match of feed, water quality management and density control are important for the seed rearing of P. crocea. The results provide the reference for future P. crocea large-scale artificial breeding.
