The movement of a trolling depressor and a jig is important for catching the target species.The experiments were conducted using a flume tank in order to clarify the movement of the trolling depressor and the jig. Thelength of main line was 2.16 m and the flow speed was 1.5 m/s. The angle where the main line was connected to the trolling depressorwas changed from 40 to 50 degrees. The tension of main line was measured by using a three component load cell. The movement ofthe trolling depressor was recorded through a digital video camera.The period of the y-component’s line tension was twice as long as the x and z component’s. The period of the movement and thesize of y-component’s displacement of the trolling depressor were increased when the angle where the line was connected to thetrolling depressor was changed from 40 to 50 degrees.
