采用混合催产剂型,对池塘培育成二冬龄的翘嘴红鲌亲鱼四批次共120组进行一次性催产注射,收集鱼卵进环道孵化。水温29℃,效应时间4h,共计产翘嘴红鲌鱼卵928万粒,经16~20h孵出全长5.23~5.25mm仔鱼378万尾,水温27~31℃需60h平游。亲鱼运输成活率100%,产后24h平均成活率83%,催产率30.4~93.5%,受精率40.4~84.0%,孵化率40.6~60.0%,在江西首次突破了池养翘嘴红鲌人工繁殖关,初步掌握了翘嘴红鲌规模化人工繁育技术。 A mixed oxytocin model was used to make one-time oxytocin injection in 120 groups of four batches of Cichlium angustifolia raised into two winter-age ponds to collect the eggs and hatch into the roundabout. Water temperature 29 ℃, effect time 4h, a total of 9280000 calyx red snapdragon eggs, after 16 ~ 20h hatched full-length 5.23 ~ 5.25mm 3.78 million larvae, water temperature 27 ~ 31 ℃ 60h flat swim. The survival rate of broodstock was 100%, the average survival rate was 83% after birth, the rate of 30.4-93.5%, fertilization rate 40.4-84.0%, hatching rate 40.6-60.0% , Initially mastered the large-scale artificial Alice Calyx breeding technology.
