摘　　要：对16尾性腺发育较好的5龄日本黄姑鱼亲鱼进行人工促熟,获自然产优质受精卵1.45×106粒,孵出仔鱼1.20×106尾,孵化率为82.8%;在水温16.8～24.6℃,盐度23.2～29.9,溶解氧5.7～7.8 mg/L的条件下,历经48 d的培育,获平均全长4.10 cm的幼鱼6.48×105尾,育苗成活率54.0%。16 Nibea japonica parent fishes naturally reproduced 1.45 ×10^6 good eggs after artificial increase to get sexual matured. 1.20×10^6 arvaes are hatched from 1.45×10^6 fertilization eggs, the hatching rate was 82.8%. The water temperature was between 16.8-24.6 ℃ ,salinity 23.2-29.9, the oxygen 5.7-7.8 mg/L during the experiment. After 48 days, a total of 6.48×10^5 young fishes were reared, with average total length of 4.1 cm and survival rate of 54.0%.
