RECENT PROGRESS IN THE CONTROL OF FISH BEHAVIOUR.

Abstract

This study gives a survey of recent activities in developing techniques for controlling fish behavior over short and medium distances. The bases for control are described with reference to the sensory system of the fish and a simple model of fish behavior. It is suggested that an effective way of controlling fish behavior is by means of conditioning, in which reward or punishment is used in connection with an acoustical or visual signal. A number of possible applications which have been tested in practice are described.
