To address growing concern over the impact of anthropogenic sound on fishes, a series of experiments was conducted that exposed several fish species to high-intensity low-frequency naval sonar. This study extends auditory findings by adding largemouth bass, yellow perch, and channel catfish. No effects on hearing were found in largemouth bass and yellow perch and only small effects in channel catfish (a fish with morphological adaptations for enhanced pressure reception). Together with prior findings, these results suggest limited impact on hearing from high-intensity sonar. Susceptibility may be due to genetic stock, developmental conditions, seasonal variation, and/or buoyancy during exposure.
为了解决人们对人为噪音对鱼类影响的日益关注，进行了一系列实验，使几种鱼类暴露在高强度低频海军声纳下。这项研究通过增加大嘴黑鲈、黄鲈和斑点叉尾鮰，扩展了听觉研究结果。在大嘴黑鲈和黄鲈中没有发现听力影响，而在斑点叉尾鮰中只有很小的影响（一种具有增强压力接收的形态适应的鱼类）。与之前的发现一起，这些结果表明高强度声纳对听力的影响有限。易感性可能归因于遗传种群、发育条件、季节性变化和/或暴露期间的浮力。
