A constant light was used in most of these studies, however, the influence of the inconstant light on a fish school's behavior has hardly been examined, in spite of great concern about the effect of such stimulation. The aim of this study was to clarify, from an ethological point of view, that an inconstant lighting condition, in which light goes on and off with a short cyclical time as an intermittent or flickering light,would give a different stimulation from that of a constant light to fish. The observations of the fish school's behavior in response to intermittent lights which have different blinking frequencies and contrast ratios between bright and dark light intensities and different wavelengths of lights were conducted. Then the difference between the fish school's behavior in response to the intermittent light under a state of dark adaptation and under light adaptation was examined by changing the background irradiances under these projected lights. In order to apply the obtained results to controlling the swimming behavior of a fish school, a prototype multiple beam projector was constructed and used to examine the barrier effect of a leader net made of projected beams, upon the behavior of fish.}, pages = {23--53}, title = {断続光に対するマアジの行動反応に関する研究}, volume = {2}, year = {1989} }
