1) An analysis of the dynamic motion of offshore fishery cages was presented. It was found that waves force acting on a floating structure surrounded by plain nets were estimated by numerical model. The results of numerical simulation were in good agreement with those of laboratory tests2) We developed a device of measurements of oscillations for fish cages in filed. This device consists of a xyz accelerometer, buttery, a tiltometer and an azimuthal compass. The displacements of fish cages are estimated by integrating the results obtained from the accelerometer.3) Filed observations were curried out to obtained the acceleration of the movement of the offshore fish cages. The site was at Odawara in Kanagawa Prefecture facing Pacific Ocean. The test area was 70m water depth. But the data could not be obtained because of trouble of the device. Now we are currying out the filed observation at Odawara after repairing the device.

1)对近海渔业网箱的动力学运动进行了分析。结果表明，作用在平面网围浮式结构物上的波浪力可用数值模型估算。数值模拟的结果与实验结果吻合较好。2）研制了一套现场鱼笼振动测量装置。该装置由一个xyz加速度计，黄油，倾斜仪和方位罗盘。通过对加速度计测量结果的积分，估算了网箱的位移。3）对现场观测数据进行了处理，得到了近海网箱的运动加速度。遗址位于面向太平洋的神奈川县小田原。试验区水深70米。但由于设备故障，无法获得数据。现在我们正在小田原修理设备后进行现场观察。
