摘要

It has been suggested that most teleost fishes cannot detect sounds higher than 2 or 3 kHz (ref. 1). However, we report here that at least one species of clupeid fish (herrings and shads), the American shad (Alosa sapidissima), can detect sounds up to180 kHz. We speculate that clupeids are able to detect the ultrasonic clicks of one of their major predators, echolocating cetaceans. Blueback herring swim away from echo-sounders, indicating that they may be able to detect ultrasound, and ultrasound isused to keep several clupeids from entering water intakes of electric power-generating plants. But it was not clear whether the fish were detecting the ultrasonic frequencies, or whether they were detecting lower-frequency side-bands associated with the pulsed sounds.
