| 摘要: |
| 光周期是鱼类季节性繁殖最可靠的环境信号。红鳍东方鲀(Takifugu rubripes)是一种春季产卵鱼类, 具有非常高的经济价值。为了探究光周期调控对红鳍东方鲀成熟产卵时间的影响, 在循环水养殖条件下开展了本研究。将90尾亲鱼随机分配至加速组和自然组。自然组亲鱼在3月产卵, 而加速组亲鱼在1月产卵, 最早产卵时间提前约2个月。结果表明, 加速光周期季节变化速率能够促进红鳍东方鲀性腺成熟。光周期调控方法能够应用于红鳍东方鲀全年繁殖调控。 |

| Abstract: |
| Photoperiod is the most predictable cue of seasonal reproduction in fishes. The tiger puffer Takifugu rubripes is a spring spawning teleost fish species with a high market value. We assessed the effect of photoperiod manipulation on the spawning time of tiger puffer in the recirculating aquaculture system. A total of 90 tiger puffer adults were subjected to natural group and accelerated group for almost a year. The fish exposed to natural photoperiod spawned in March, while those exposed to manipulated photoperiod spawned almost 2 months earlier than the former. These results suggest that the photoperiod plays an important role in accelerating maturation and spawning. The present findings can be implemented in the tiger puffer aquaculture industry to achieve year-round spawning. |
