Some techniques with air bubble, electricity and light have been developed to avoid fish from entering intake gates. In recent years, action control techniques of fish with magnet are evaluated. Hutchinson et al. achieved a certain result to prevent the entrance of several species of sharks into longlines by mounting magnets on longlines. Smith & O’Connell showed that magnet worked on Raja clavata to prevent alike. Ward et al. reported the research that Danio rerio which belongs to fresh water fish changed the swimming speed and the swimming direction near the magnets. However, few studies about action control techniques of fresh water fish with magnet have been conducted. In this study, the magnetic flux density of the magnets put on the bottom of the side wall in the circular pool is changed to make clear effects of magnetic force on the swimming behavior of the isolated Zacco platypus in static water. The swimming position, the swimming speed, the fish direction and the turning angle are analyzed by capturing the swimming in the experiment. As a result, Zacco platypus is unaffected by magnet force under the condition of this experiment., The 11th Pacific Symposium on Flow Visualization and Image Processing, 2017, 1-3 December, Kumamoto, Japan}, publisher = {11th Pacific Symposium on Flow Visualization and Image Processing(PSFVIP-11 )}, title = {Effects of magnetic force on swimming behavior of isolated Zacco platypus in static water}, year = {2017}, yomi = {オニツカ, コウキ} }
