| 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。

Study on Outdoor Large-scale Breeding of Bidyanus bidyanus |
| |
| Abstract: | 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‰-4‰ 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 × 104 (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. |
