Human‐generated noises are considered as underwater sound pollution with potential short‐ or long‐term impacts on behavioural responses and physiological reaction of aquatic living organisms. Few investigations are available so far on long‐term influences of impulsive and continuous sound sources on physiological response of fish. In the present study, opercula beat rates and pectoral wing rates were monitored as a physiological stress response of ventilation in Nile tilapia (Oreochromis niloticus) exposed to long‐term repeated and continued sounds generated from underwater construction work. Fish responded to underwater sound treatment with significantly increased opercula beat—and pectoral wing movements. Maximum ventilation rate was observed as a startle response of fish at initial exposure to underwater sound. The ventilation rates remained at high levels over the first 4 weeks and showed a declining trend thereafter. Fish growth was almost stable for the first 4 weeks, but shifted forward from day 45 onwards. We found strong evidence that fish could attune to repeated playbacks of underwater noise exposures since we found higher specific growth rates for the sound exposed fish from day 45 onwards until day 120, a so‐called ‘catch‐up growth endeavour’.

水下钻探和打桩噪声对尼罗罗非鱼生长和生理响应的声学影响

人为产生的噪声被视为水下声音污染，可能对水生生物的行为反应和生理反应产生短期或长期影响。到目前为止，很少有关于脉冲和连续声源对鱼类生理反应的长期影响的研究。在本研究中，以尼罗罗非鱼（Oreochromis niloticus）的通气生理应激反应监测的跳动率和胸翼率）暴露于水下建筑工作产生的长期重复和持续的声音中。鱼对水下声音处理的反应是显着增加了—盖跳动和胸鳍运动。观察到最大通风率是鱼类在初次暴露于水下声响时的惊吓反应。在开始的4周内，通气率一直保持较高水平，此后呈下降趋势。在最初的4周中，鱼的生长几乎是稳定的，但是从第45天开始向前移动。我们发现有力的证据表明，鱼类可能会受到水下噪声暴露的反复影响，因为我们发现，从第45天到第120天，暴露于声音的鱼类的比生长速率更高，这就是所谓的“追赶性生长努力”。
