- Abstract
Presents a study that describes how individual whitefish, Coregonus lavaretus, react to strobe light. Performance of field experiments in a net enclosure on fish tagged with ultrasonic transmitters; How a strobe light array was switched on near the tagged fish; Reaction of the fish to the light by moving away from it with increased swimming speed; How aquarium experiments under controlled conditions were carried out in rearing tanks at Saimaa Fisheries and Aquaculture Station in Finland; Directing of a strobe light from the side of the basin and behind the fish at a close range; Response of the fish to the light; How the fish did not change its swimming direction when light was aimed from behind; Conclusions that the strobe light may be used to prevent fish from swimming into a specific area; Discussion about implications for development of new fishing equipment and research concerning fishes in areas with water power stations.
