The objective of this report was to determine whether any quantity of underwater sound would attract or repel young salmon. Frequencies from 5 to 20,000 cycles per second were tested in an experimental tank and in open water. Two types of transducers were used. Other than an initial "start" by the fish, no reaction was demonstrated. Apparently, fish are conditioned almost instantaneously to sounds. It was concluded that sound waves were ineffective as an attracting or repelling force.
