2012年~2014年,作者在山东省海洋生物研究院鳌山卫中试基地进行了大泷六线鱼(Hexagrammos otakii)全人工繁育研究,通过人工促熟、激素诱导,培育 F1代全人工亲鱼558尾(雄鱼231尾,雌鱼327尾),获得受精卵33.0万粒,孵化 F2代仔鱼30.0万尾,受精率98%,孵化率91%。在水温16~17℃、盐度31、pH 7.8~8.1、溶解氧6 mg/L 条件下,历时110 d,培育平均全长6.2 cm F2代苗种11.7万尾,苗种成活率39%。作者在国内外首次开展了大泷六线鱼全人工繁育技术研究,丰富了大泷六线鱼养殖基础资料,为大泷六线鱼产业的发展奠定基础。%This article presents the results of an artificial technique used for breeding the fat greenling Hexagrammos otakii from 2012 to 2014 together with key technologies, such as broodstock culture, induced spawning, egg incuba-tion, and larval culture. Using 558 first filial broodstocks (231 males, 327 females), 30×104 larvae were hatched from 33×104 artificially fertilized eggs. The average rates of fertilization and incubation reached 98% and 91%, respectively. Total 11.7×104 healthy second filial fries were successfully cultivated with an average total length of 6.2 cm and sur-vival rate of 39% at a water temperature of 16–17℃, salinity 31, pH 7.8–8.1, and oxygen 6 mg/L. This study was conducted for the first time with Hexagrammos otakii artificial breeding technology, which enriched the Hexa-grammos otakii base data and laid a solid foundation for the development of Hexagrammos otakii industry.
