ANALYSIS OF SOUND SPECTRA IN YELLOWSTONE LAKE IN RELATION TO ORIENTATION AND HOMING MOVEMENTS OF CUTTHROAT TROUT (SALMO CLARKI).
Abstract
Orientation and homing studies on the cutthroat trout (Salmo clarki) in Yellowstone Lake have been carried out with emphasis on olfaction and vision. Homing could not be explained in terms of visual and olfactory mechanisms alone. Since fishes perceive low level acoustic noise by means of the acoustico-lateralis system, it was hypothesized that cutthroat trout might cue to the acoustic spectrum produced by streams. The present study had as its objectives to determine if characteristic ambient acoustic-pressure spectrum levels occur in the area of spawning tributaries, to record and analyze cutthroat trout sounds and to determine an audiogram for this fish.
