| 摘 要： | 2007-2008年对39尾,4～5龄,雌鱼体长36～41 cm,体质量 2.5～2.9 kg,雄鱼体长 32～35 cm,体质量 1.5～1.6 kg的缺帘鱼亲鱼用 HCG、PG、LHR-A_2、DOM 4种催产药物,按5种组合(设置每千克体质量:HCG 300 IU + LHR-A_2 2.5 μg + DOM 2 mg、 HCG 3500 IU +PG 2 mg + LHR-A_2 3 μg + DOM 3 mg、PG 4 mg + LHR-A_2 6 μg + DOM 2 mg、HCG 700 IU + DOM 2 mg、LHR-A_2 5 μg + DOM 4 mg)进行催产试验,催产水温27～28 ℃,采用两针注射,效应时间 9～10h.5种组合的平均催产率分别为75.2%、75.4%、75.5%、60%、60.3%;平均受精率为76.6%;平均孵化率为68.5%;平均出苗率为72.2%;出膜时间为17～18 h;孵化水温27～28 ℃,20尾雌鱼共产卵59 560粒;共获苗种23 469尾.

| Abstract: | A total of 39 broodstock of 4 to 5 year old Brycon cephalus(female with body weight of 2.5～2.9 kg and body length of 36～41 cm; male with body weight of 1.5～1.6 kg and body length of 32～35 cm)was induced to spawn by two hormonal injection at an interval of 6～7 hours at a rate of HCG 300 IU +LHR-A_2 2.5 μg + DOM 2 mg/kg,HCG 3500 IU+PG 2 mg+LHR-A_2 3 μg +DOM 3 mg/kg,PG 4 mg+LHR-A_2 6 μg+DOM 2 mg/kg, HCG 700 IU+DOM 2 mg/kg, and LHR-A_2 5 μg+DOM 4 mg/kg at water temperature of 26～28 ℃ from 2007 to 2008. There were 75.2%, 75.4%, 75.5%, 60% and 60.3% of the broodstock which spawned 9～10 hours after the injection with fertilization success of 76.6%. Total of 59560 fertilized eggs and 23469 larvae(incubation period of 17～18 h) were obtained with hatching rate of 68.5%. |
