[0059] (4) Different float colors or markings make it easier for farmers to identify and locate oyster cages with different breeding dates or durations, thus improving management efficiency.

[0060] (5) By setting up detachable cages and aquaculture units, the installation and harvesting of mechanized operation vessels are facilitated, reducing the labor intensity of oyster harvesting and improving work efficiency. At the same time, during the aquaculture process, the cages can be easily disassembled to clean the attachments on the cages and oyster cages, promoting oyster growth.

[0061] (6) The multi-layered partitions and flexible cable design inside the oyster cage help improve the oyster cage's resistance to wind and waves and the yield per unit water volume, while providing a good growth environment for oysters.

[0062] (7) The special coating on the surface of the float reduces the adsorption of algae and plankton, which helps to keep the water clean.
