Impingement of fish into hydroelectric dams and water intakes to power plants is a significant problem in many parts of the United States. The problems are two-fold. First, many fish are killed when they encounter the dams or intakes and cannot escape the rapidly flowing water. Second, there is potential damage to the power generating equipment due to the large number of impinged fish. Thus, it is of considerable economic importance to find ways to prevent the interactions between fish and the dams or power plant intakes. One of the most successful methods developed to date is the use of high frequency sound to repel clupeid fishes (herrings and relatives) from these obstacles. For reasons that are yet unknown, these commercially important species swim away from these sounds. At the same time, we know very little about how clupeids detect the ultrasonic sounds, or the kinds of sounds that can be most successfully used to repel the fish. The purpose of this study is to examine the hearing ability of clupeids in order to better understand how they detect sounds, and which sounds they detect, with the ultimate goal being to develop methods to more effectively prevent the impingement of clupeids at dams and power plant intakes.

在美国许多地方，将鱼类撞击到水力大坝和摄入厂的水中是一个重要的问题。问题是两个方面。首先，许多鱼在遇到大坝或进气口时被杀，无法逃脱迅速流动的水。其次，由于大量撞鱼，发电设备可能会损坏。因此，寻找防止鱼与大坝或发电厂摄入量之间相互作用的方法是非常重要的。 迄今为止开发的最成功的方法之一是使用高频声音从这些障碍中驱除clupeid鱼（鲱鱼和亲戚）。由于尚不清楚的原因，这些商业上重要的物种远离这些声音。同时，我们对Clupeids如何检测超声波声音或最成功用于排斥鱼类的声音的方式了解甚少。这项研究的目的是检查clupeids的听力能力，以便更好地了解它们如何检测声音，并检测到哪些声音，最终目标是开发方法，以更有效地防止在大坝和发电厂摄入量中撞击clupeids。
