| 中文摘要: |
| 研究了NaCl盐度（0、1、3、5、7、9）和NaHCO3碱度（1 mmol/L、10.00 mmol/L、15.85 mmol/L、25.12 mmol/L、39.81 mmol/L、63.10 mmol/L）对松浦镜鲤（Cynipus carpio L.）、方正鲫（Carassius auratus gibelio Bloch）的孵化率、畸形率以及仔鱼24、48h存活率的影响。①盐度实验结果表明：松浦镜鲤在盐度为0~1时，受精卵的孵化率较高平均为72.40% ± 6.09%；在盐度0~3时，孵出的仔鱼畸形率较低平均为6.02% ± 1.87%，48h的存活率较高平均为94.99% ± 6.44%。方正鲫在盐度0~3时，受精卵的孵化率较高平均为68.03% ± 15.44%；在盐度0~5时，孵出的仔鱼畸形率较低平均为7.95% ± 3.24%，48h的存活率较高平均为88.52% ± 9.19%。②碱度实验结果表明：这两种鱼的孵化率在碱度1~25.12 mmol/L时较高，松浦镜鲤平均为47.96% ± 8.43%，方正鲫平均为66.23% ± 18.11%；畸形率在碱度1~15.85 mmol/L范围内较低，松浦镜鲤平均为12.47% ± 3.77%，方正鲫平均为12.46% ± 8.44%；48h存活率在碱度1~15.85 mmol/L时较高，松浦镜鲤平均为96.16% ± 5.04%，方正鲫平均为85.62% ± 3.73%。综合各项指标表明，松浦镜鲤和方正鲫人工孵化用水建议盐度应控制在3以内，碱度应控制在15 mmol/L以内。 |

| Influences of different NaCl salinity (0, 1, 3, 5, 7, 9) and NaHCO3 alkalinity (1.00 mmol/L, 10.00 mmol/L, 15.85 mmol/L, 25.12 mmol/L, 39.81 mmol/L, 63.10 mmol/L) on hatching rate, deformity rate of the embryos, and 24, 48h survival rate of newly hatched larvae of Songpu mirror carp (Cynipus carpio) and gibel carp (Carassius auratus gibelio) were investigated in this study. The significant differences between the results and salinity or alkalinity were analysed with Duncan’s multuple comparison by using SPSS 17.0 software. ① The results of the experiments about salinity showed that the high hatching rates of Songpu mirror carp were observed when the salinity ranged from 0 to 1, which was 72.40% ± 6.09% on average. The deformity rates of Songpu mirror carp were lower obviously at salinities 0 to 3 than other groups, and the mean deformity rate was 6.02% ± 1.87%, meanwhile, the mean 48h survival rate was 94.99% ± 6.44%. For Gibel carp, high hatching rates were observed at salinities from 0 to 3, which was 68.03% ± 15.44% on average. The deformity rates of Gibel carp were low obviously at salinities 0 to 5, and the mean deformity rate was 7.95% ± 3.24%, meanwhile, the mean 48 h survival rate reached 88.52% ± 9.19% (Fig.1). ② The results of the experiments about alkalinity showed that the high hatching rate of these two fishes were observed when the alkalinity ranged from 1.00 to 25.12 mmol/L, and it was 47.96% ± 8.43% for Songpu mirror carp and 66.23% ± 18.11% for Gibel carp on average. The deformity rates of these two fishes were lower significantly when the alkalinity ranged from 1 to 15.85 mmol/L, and it was 12.47% ± 3.77% for Songpu mirror carp and 12.46% ± 8.44% for Gibel carp on average. When the alkalinity ranged from 1 to 15.85 mmol/L, the mean 48h survival rate of Songpu mirror carp was 96.16% ± 5.04%, and the mean 48h survival rate of Gibel carp was 85.62% ± 3.73% (Fig.2). In conclusion, for Songpu mirror carp and gibel carp, the suitable salinity for the hatch of fertilized eggs and the survival of larvae should be lower than 3, and the suitable alkalinity should be lower than 15 mmol/L. |
