[0003] However, traditional cage farming has many disadvantages, such as (1) the traditional cage farming process requires a lot of manual labor throughout the process, resulting in high labor costs; (2) the water temperature in offshore farming varies greatly, and abalone is a cold-water organism. The seawater temperature in coastal areas rises after May, which is not conducive to the survival and growth of farmed abalone; (3) offshore farming space is crowded, and the offshore area has long been occupied by various farming cages. Not only is the space small, but the seawater is also seriously polluted, making it difficult to expand large-scale abalone farming; (4) there are many strong typhoons in the offshore area, and it is difficult to carry out farming operations under typhoon conditions, which may even result in partial losses.
