As the results of calculation through these records and actual catches, they knew that the catching rate was about 6% in this fisheries and that 98% of this fish-stocks was caught in a half year. This phenomena must have the most serious means in the fisheries on this bay. It is belived that the method to confirm the conditions of fish schools by vertical and horizontal fish-finders must be the best way to investigate the fish-stocks in a fishing ground.}, pages = {77--81}, title = {灯に集まる魚群の立体的記録例について}, volume = {6}, year = {} }
