 note = {Studies have been made to obtain the average speed and the flowing direction of oceanic currents or their general conditions from the distance and time of the drift of the long-line set in the sea. The authors studied the influence of the known direction and speed of oceanic currents on the style of the long-line in a horizontal direction between the time it is streamed down and the time it is hauled up. The present research was made on the basis of the data collected in the Indian Ocean during the three years from 1967 to 1969. But as the survey was made in the same season every year, the direction of the oceanic currents and that of the monsoon were found to show the same trend at the time of survey. This fact made it impossible to examine the currents in all directions against the streaming direction of the long-line. It was attempted to obtain the variation of the style of streamed tuna longline by the force of the currents from the direction in the third quadrant against the streaming direction of the long-line. When the direction of the long-line at its streaming time was placed on the Y axis, and the variation of the style of the long-line between the time of its setting and the time of its taking in on the X axis, a formula Y=-1.59X was obtained., マグロ延縄の投縄方向に対し海流を第3象限より受ける場合,投縄時の縄成りと揚縄時の縄成り変化傾向を求めた. 投縄時の縄成りをY軸に投縄時の縄成りに対する揚縄時の縄成り変化をX軸にとるとY=-1.59Xを得た., 長崎大学水産学部研究報告, v.27, pp.91-94; 1969},
