中層浮魚礁設置精度の向上に関する研究

抄録

A midwater artificial floating reef is set in the middle layer of the depth from 500m to 1500m by sinking anchor from the sea surface. The bottom profile where the midwater artificial floating reef is set is usually not flat but has a steep slope. If the anchor is not fixed at the proper position, the location of artificial floating reef deviates from the intended position. The fish-swarming effect of the artificial floating reef depends on the position of the body. Therefore, it is necessary to set the mooring anchor at the intended position.
