In the previous cages, only the net was floated in the water with a float and a sinker, and suspended in the water. This simple cage is not used now. With the development of the times, today's cage practices are different, and some are made into a hexahedron frame, which can be made of metal, wood or bamboo. After the installation of the whole frame, the ability to resist wind and waves in the water is strong, such as lack of oxygen in the box, and the overall movement of the cage is very convenient. It is also very convenient to use the sun drying net to eliminate the attachments, but it is troublesome to carry. The cage frame also has only a flat box, and is equipped with a float and a sinker to suspend the net in the water. This kind of cage drying net is very simple, and the handling is very simple.
