以前用微型深度记录仪测量了延绳钓渔具中鱼钩的安装深度。研究假设悬链线形状的延绳钓渔具的模拟基于这些数据已经完成。不过，这条分支线路是与主线纠缠在一起，还是随水流而流，不得而知。在本研究中，使用了通常用于调查海洋生物水下行为的超声波定位系统和带有通信卫星的浮标，并测量了金枪鱼延绳钓渔具的三维水下形状。可以真实的监测渔具的变化。提出了在今后技术改进的基础上实现高精度测量的可能性。
The installation depth of the hook in longline fishing gear has previously been measured with micro depth loggers. Research that assumes the catenary shape of longline fishing gear by a simulation based on these data has been done. However, it was not known whether the branch line was tangled with the main line or flowed with the current. In this research, an ultrasonic positioning system generally used to investigate the underwater behavior of marine organisms, and a buoy with a communications satellite, have been used, and the 3-dimensional underwater shape of tuna longline fishing gear was measured. It was possible to monitor changes in fishing gear in real time. The possibility of high precision measurement was suggested with future technical improvement.
