Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. Generally comprises the whole process of cultivating aquatic products from seedlings under artificial feeding management. In a broad sense, this may also include the proliferation of aquatic resources. Aquaculture has modes of rough culture, intensive culture, high-density intensive culture and the like. The rough culture is to put seedlings in medium and small natural waters and to culture aquatic products such as fish in lakes and reservoirs, shellfish in shallow seas and the like by completely relying on natural baits. Intensive culture is to culture aquatic products such as pond fish culture, net cage fish culture, fence culture and the like in a small water body by using bait casting and fertilizing methods. The high-density intensive culture adopts methods of flowing water, controlling temperature, increasing oxygen, feeding high-quality baits and the like to carry out high-density culture in a small water body so as to obtain high yield, such as flowing water high-density fish culture, shrimp culture and the like. The former net cage only uses a floater and a sinker for the net to open the net in water and suspend the net in the water. The simple net cage is mostly unused at present. With the development of times, the current net cages are different in practice, some of the net cages are made into hexahedral frames, and the hexahedral frames can be made of metal, wood or moso bamboos.
