ABSTRACT:
Acoustic signals and hydraulic pressure variations which influence fish bvior in bodies of water are measured and recorded by apparatus simulating a fish immersed in water, fitted with piezoelectric transducers and connected by wiring to remote amplifying and recording means. Such data are correlated with fish behavior for the purpose of developing methods of diverting fish from such areas of danger as the intake piping of hydroelectric power generating turbines and pumping stations.
