虽然在世界上许多不同的地方都研究过有刺鱼类，但在北美淡水系统中进行的研究很少。这项研究的目的是对纽约哈德逊河的水下声音进行分类和识别。我们用一个由水听器、数字录音机和防风雨外壳组成的自主水下聆听系统记录水下声音。2003年，在哈德逊河沿岸的两个地点进行了大约164小时的录音。其中一个地点位于曼哈顿岛河口附近。第二个地点位于哈德逊河国家河口研究保护区蒂沃利湾上游153公里处。此外，本署亦于二零零四年对捕获的鱼类进行录音及试听，以识别提沃利湾的生物及未知声音。我们总共录下了62种不同的声音。只有四种鱼类可以识别出声音：牡蛎蟾蜍鱼Opsanus tau，条纹棘鳗Ophidion marginatum，棕色牛头鱼Ameiurus nebulosus和海峡鲶鱼Ictalurus punctatus。另外21种声音被归类为生物，5种为非生物，32种为未知。我们认为，许多被归类为生物和未知的声音实际上是由鱼类产生的，但由于缺乏对哈德逊河淡水和河口鱼类声音产生的研究而无法识别。未来的研究重点是识别这些未知的水下声音，这将为哈德逊河的生态提供新的见解。我们在哈德逊河中记录的水下声音的多样性强烈表明声音产生是水生系统的重要行为，被动声学可以成为研究河流生态的重要新工具。
Although soniferous fishes have been studied in many different parts of the world, very few studies have been conducted in North American freshwater systems. The purpose of this study was to catalog and identify types of underwater sounds in the Hudson River, New York. We recorded underwater sounds with an autonomous underwater listening system consisting of a hydrophone, digital sound recorder, and weatherproof housing. Approximately 164 h of recordings were made from two sites located along the Hudson River during 2003. One site was located near the mouth of the river on Manhattan Island. The second site was located 153 km upriver within Tivoli Bays at the Hudson River National Estuarine Research Reserve. Additional manned recordings and sound auditioning of captured fishes were conducted in 2004 to identify biological and unknown sounds from Tivoli Bays. In all, we recorded 62 different sounds. Only four sounds could be identified to fish species: oyster toadfish Opsanus tau, striped cusk-eel Ophidion marginatum, brown bullhead Ameiurus nebulosus, and channel catfish Ictalurus punctatus. An additional 21 sounds were categorized as biological, 5 as nonbiological, and 32 as unknown. We believe that many of the sounds classified as biological and unknown are in fact produced by fishes but could not be identified due to the scarcity of studies on the sound production of freshwater and estuarine fishes of the Hudson River. Future research focused on the identification of these unknown underwater sounds will provide new insights into the ecology of the Hudson River. The diversity of underwater sounds we recorded in the Hudson River strongly suggests that sound production is an important behavior in aquatic systems and that passive acoustics can be an important new tool for the study of the river's ecology.
