Most of the existing deep-sea net cages used at present cannot keep balance when ascending and descending operations are carried out, and the transverse movement is too large, so that the net cages are easy to incline and even overturn. Even if a structure for fixing the net cage frame, such as a pile supporting frame, is adopted, the net cage is mainly supported by pile supporting, 4 corner piles are generally bundled by materials such as logs or moso bamboos, and then interval piles are arranged on each edge at intervals, and the netting can be directly hung on the piles. However, in the deep and open sea cage culture process, the pile supporting frame is often damaged by wind and waves and is easy to rub and collide with the cage frame, so that abrasion and damage are generated, and huge economic loss is caused.

The invention also provides a using method of the anchoring system, wherein the fixed cables of adjacent net cages are combined together, the adjacent net cages share the edge of one fixed cable, the connected fixed cables are arranged at a certain depth under water, the anchoring cables at the periphery of the anchoring system fix the horizontal direction of the fixed cables to prevent horizontal drift, the first floater fixes the vertical direction of the fixed cables, the fixed cables basically keep stable in the horizontal and vertical directions, the net cages take the fixed cables as fixed shafts and are pulled by the hanging cables, and the buoyancy of the net cages is changed, so that the net cages can ascend or descend to the same height above or below the fixed cables, and the positions of the fixed cables are unchanged.
Compared with the prior art, the invention has the beneficial effects that:
the anchoring system can enable the net cage to ascend or descend to the same height by taking the fixed mooring rope as the fixed shaft, and the fixed mooring rope is fixed underwater, so that the length of the anchoring mooring rope is saved, and the anchoring mooring rope is not easily influenced by wind and waves.
