The aim of this study was to explore an emerging discipline addressing the impact of anthropogenic noise on larval stages of marine organisms. We assessed the influence of boat noise on the feeding behaviour of the pelagic larvae of winter flounder (Pseudopleuronectes americanus, Walbaum, 1792). The hypothesis was that boat noise influences the feeding behaviour of P. americanus flounder larvae independently of prey density. Aquaria containing P. americanus larvae were placed in water baths in which boat noise was diffused for the “noise” treatment and compared to control aquaria with no sound emissions. Larvae were filmed using cameras placed above the aquaria and their behaviour was recorded. Larvae exposed to anthropogenic noise displayed significantly fewer hunting events than controls, and their stomach volumes were significantly smaller. This noise effect was the same at all prey densities used, suggesting that larval feeding behaviour is negatively impaired by anthropogenic noise.

人为船舶噪音降低了冬季比目鱼幼虫的摄食成功率 (Pseudopleuronectes americanus)

本研究的目的是探索一门新兴学科，解决人为噪声对海洋生物幼虫阶段的影响。我们评估了船舶噪音对冬​​季比目鱼（Pseudopleuronectes americanus，Walbaum，1792）远洋幼虫摄食行为的影响。假设是船只噪音影响美洲比目鱼幼虫的摄食行为，与猎物密度无关。含有美洲原虫幼虫的水族箱被放置在水浴中，在水浴中，船的噪音被扩散以进行“噪音”处理，并与没有声音发射的对照水族箱进行比较。使用放置在水族箱上方的照相机拍摄幼虫并记录它们的行为。暴露于人为噪音的幼虫比对照组表现出明显更少的狩猎事件，并且它们的胃体积明显更小。
