Environmental assessments of underwater noise on marine species must be based on species-specific hearing abilities. This study was to assess the potential impact of underwater noise from the East China Sea Bridge wind farm on the acoustic communication of the marbled rockfish. Here, the 1/3 octave frequency band of underwater noise was 125 Hz with the level range of 78–96 dB re 1 μPa, recorded at distances between 15-20m from the foundation at wind speed of 3–5 m/s. Auditory evoked potential (AEP) and passive acoustic techniques were used to determine the hearing abilities and sound production of the fish. The resultes showed the lowest auditory threshold of Sebastiscus marmoratus was 70 dB at 150 Hz matching the disturbance sound ranging 140–180 Hz, which indicating the acoustic communication used in this species. However, the frequency and level of turbine underwater noise overlapped the auditory sensitivity and vocalization of Sebastiscus marmoratus. The wind turbine noise could be detected by fish and may have a masking effect on their acoustic communication. This result can be applied for further to the assessent of fish species released into offshore wind farm marine ranch.

风力涡轮机水下噪声对大理石石斑鱼（Sebasticus marmoratus）的潜在影响

对海洋物种水下噪声的环境评估必须基于特定物种的听力能力。本研究旨在评估来自东海大桥风电场的水下噪声对大理石岩鱼声学通信的潜在影响。在这里，水下噪声的 1/3 倍频程频带为 125 Hz，电平范围为 78-96 dB re 1 μPa，记录在距离基础 15-20 m 之间，风速为 3-5 m/s。听觉诱发电位 (AEP) 和被动声学技术用于确定鱼的听力能力和声音产生。结果显示Sebastiscus marmoratus的最低听觉阈值在 150 Hz 时为 70 dB，与 140-180 Hz 范围内的干扰声音相匹配，这表明该物种使用了声学通信。然而，涡轮机水下噪音的频率和水平与Sebastiscus marmoratus的听觉灵敏度和发声重叠。风力涡轮机的噪音可以被鱼检测到，并可能对它们的声学通信产生掩蔽效应。该结果可进一步用于评估释放到海上风电场海洋牧场的鱼类。
