Abstract

Three sound-emitting devices have been developed to control fish movement near generating stations. The devices have the advantage of increased flexibility, in terms of frequency and amplitude, over most previous sonic devices, and show potential for repelling and/or attracting some species of fish. Design characteristics of the equipment and results of field testing are described in this paper.
