Reactions in individual fish to strobe light. Field and aquarium experiments performed on whitefish (Coregonus lavaretus)


This study describes how individual whitefish Coregonus lavaretusreact to strobe light. Field experiments were performed in a net enclosure on fish tagged with ultrasonic transmitters. A strobe light array was switched on near the tagged fish. The fish moved away from the light and increased their swimming speed. Aquarium experiments under controlled conditions were carried out in rearing tanks at Saimaa Fisheries and Aquaculture Station in Finland. A strobe light was directed from the side of the basin just ahead of, directly at, and behind the fish at a close range. In the first two cases fish responded by a distinct turn and a change in swimming direction away from the light. The fish did not change its swimming direction when light was aimed from behind. It is concluded that strobe light may be used to prevent fish from swimming into a specific area. Implications for development of new fishing equipment and research concerning fishes in areas with water power stations is briefly discussed.
