摘　　要：[目的]提高育苗存活率,并获得较为稳定的育苗效果。[方法]选择1龄以上性成熟雄鱼、3龄以上性成熟雌鱼作为亲本,采用淡水催产孵化、3‰~4‰低盐度海水育苗的方式,开展澳洲银鲈室外规模化繁育试验。[结果]3批次受精卵孵化中,孵化率分别达92%、87%、90%,平均孵化率为90%;3批次人工育苗共获160万尾鱼苗,培育4~5 cm鱼苗成活率分别为58%、31%、28%,平均育苗成活率为37%。[结论]试验表明澳洲银鲈对盐度变化有较强的适应能力,低盐度海水培育澳洲银鲈苗种是切实可行的,且生长速度快、育苗成活率高。[ Objective]To increase breeding survival rate and get stable breeding results. [ Method] The large-scale breeding of Bidyanus bidyanus in outdoor was carried out, this experiment selected over 1 age mature males and more than 3 age mature females as parents, which were hatching in fresh water and breeding in seawater with 3%c -4%c low salinity. [ Result] The hatching rates of B. bidyanus in three batch were 92% ,87% and 90% , and the average hatching rate was 90%. 160 x l〇 4 （ 4 - 5 cm in total length） fries were gained in three batch, with the survival rates of 58% , 31% and 28% respectively, and the average survival rate was 37% . [ Conclusion] The results of the trail indicated that B. bidyanus has a strong adaptability to salinity change, the new breeding model in seawater with low salinity is practicable, the growth rate is fast, and the survival rate of seedlings is high.
