珊瑚礁鱼的幼虫在其重要的定居阶段使用声音来寻找合适的栖息地。然而，由于与捕鱼、旅游以及客运和货运有关的船只活动，船只噪音在珊瑚岛和大陆架生境周围很常见，这可能导致压力和回避行为，并可能通过减少感知空间而造成掩蔽。在选择性室内实验中，以沉积期的天竺鲷（Apogon doryssa）幼鱼为对象，研究了其对5种不同噪声（礁噪声、礁+船噪声、海洋噪声、海洋+船噪声和白色噪声）的方向反应。结果显示，69%的鱼向Reef回放游去，而Reef+Boat回放期间只有56%，而44%的鱼苗远离Reef+Boat回放，而Reef回放期间只有8%。在白色噪声、海洋噪声或海洋+船噪声播放期间未观察到显著的方向响应。总的来说，这项研究表明，人为噪音可能会有破坏性的影响，鱼苗的反应，自然礁声，与船舶交通干扰的珊瑚礁栖息地的定居和人口动态的影响。
Coral reef fish larvae use sound to find suitable habitat during their vital settlement stage. Yet boat noise, which can cause stress and avoidance behaviour, and may cause masking via reduction of perceptual space, is common around coral islands and continental shelf habitats due to boat activity associated with fishing, tourism and transport of passengers and cargo. In a choice chamber experiment with settlement-stage coral reef fish larvae of the species Apogon doryssa, the directional responses of larvae were tested to 5 different noise types: Reef, Reef+Boat, Ocean, Ocean+Boat and White noise. The results showed that 69% of fish swam towards Reef playback compared with only 56% during Reef+Boat playback, while 44% of fish larvae moved away from Reef+Boat playback compared to only 8% during Reef playback. Significant directional responses were not observed during White noise, Ocean noise or Ocean+Boat noise playback. Overall, this study suggests that anthropogenic noise could have a disruptive effect on the response of fish larvae to natural reef sound, with implications for settlement and population dynamics in coral reef habitats disturbed by boat traffic.
