摘要
小黄鱼作为一种重要的海洋经济鱼类，随着过度捕捞及环境的变化，捕捞个体逐渐小型化，野生资源量不断减少，因此，开展小黄鱼的人工养殖、良种培育是未来小黄鱼研究工作的重要内容。2016年4至7月，在浙江省海洋水产研究所西轩渔业科技岛，利用620尾人工繁殖的F1代1龄小黄鱼亲鱼，通过人工促熟和激素诱导，获受精卵36万粒，获得初孵仔鱼17万尾，统计得知受精率和孵化率分别为76％和62．1％。在水温15．0-22．0℃，盐度26．28，溶解氧5．0-6．0mg／L的条件下，历经60d的培育，育成平均全长5．71±0．73cm的F2代苗种5．8万尾，育苗成活率34．12％。小黄鱼全人工繁殖取得成功，为小黄鱼的增养殖和良种选育奠定了重要基础。
As an important marine commercial fish, with the change of environment and human exploita- tion, the number of wild Larimichthys polyactis increasingly reduces. Thus, the artificial cultivation and breed- ing of L. polyactis will be the research key content in future. During the period from May to June, 2016, stud- ies on techniques of the artificial breeding of small yellow croker were executed. The results showed that： The water temperature was between 15.0-22.0 ℃, salinity 26-27, the oxygen 5.0-6.0 mg/L during the experiment. After 60 days, a total of 5.8×10^4 young fishes were reared, with average total length of 5.71±0.73 cm. The hatching rate and survival rate were 62.12% and 34.12%. The successful artificial breeding of L. polyactis lays a solid foundation for an artificial breeding and release of L. polyactis.
