The impact of boat related noise on marine life is a subject of concern, particularly for fish species that utilize acoustic communication for spawning purposes. The goal of this study was to quantify and examine the risk of boat noise on fish acoustic communication by performing acoustic monitoring of the May River, South Carolina (USA) from February to November 2013 using DSG-Ocean recorders. The number of boats detected increased from the source to the mouth with the highest detections near the Intracoastal Waterway (ICW). Boat noise frequency ranges overlapped with courtship sounds of silver perch (Bairdiella chrysoura), black drum (Pogonias cromis), oyster toadfish (Opsanus tau), spotted seatrout (Cynoscion nebulosus), and red drum (Sciaenops ocellatus). In the May River estuary, red drum may experience the greatest risk of auditory masking because of late afternoon choruses (21% time overlap with boat noise) and only one spawning location near the noisy ICW.
船只相关噪声对海洋生物的影响是一个令人关注的问题，特别是对于那些利用声通讯进行繁殖的鱼类物种。本研究的目的是通过在 2013 年 2 月至 11 月期间使用 DSG-Ocean 记录器对南卡罗来纳州梅河（美国）进行声学监测，量化和研究船只噪声对鱼类声学通讯的风险。检测到的船只数量从源头到河口逐渐增加，在近岸航道（ICW）附近检测到的船只最多。船只噪声的频率范围与银鲈（Bairdiella chrysoura）、黑鲈（Pogonias cromis）、牡蛎蟾鱼（Opsanus tau）、斑点石斑鱼（Cynoscion nebulosus）和红鼓鱼（Sciaenops ocellatus）的求偶声重叠。在梅河河口，由于下午晚些时候的合唱声（与船只噪声有 21%的时间重叠）以及只有一个靠近嘈杂的近岸航道的繁殖地点，红鼓鱼可能面临最大的听觉掩蔽风险。
