The sea cage culture has the advantages of superior water quality condition, good fish product quality, wide sea area, resource saving, flexibility, convenient management, less investment and high benefit, and the sea cage culture has the following characteristics: the sea area is wide, resources are saved, the water area of the natural sea area is wide, land is not occupied, contradictions between water source shortage and agriculture and fishing do not exist, and the development space is huge. Auxiliary energy is not needed to be provided in the culture production process, and the method is an environment-friendly and resource-saving marine agricultural production mode. And secondly, the water quality condition is superior, the fish product quality is in a natural sea area, the dissolved oxygen in the net cage can be kept above 5mg/L due to smooth water flow, the excrement of the fish body and residual bait can be quickly discharged out of the net cage, the water quality condition is good, and fish diseases are rarely caused. In addition, the cultured fish colony in the net cage is surrounded in a limited water body, the heat loss is reduced, and in addition, the auxiliary effect of natural bait in a sea area and artificial bait casting provide good environmental conditions for the growth of the fish. Therefore, the fish cultured in the net cage not only has high growth speed, but also is close to the fish quality of the natural sea area. Thirdly, the marine culture net cage is flexible and convenient to manage, and can be dragged to a proper culture sea area in a dragging mode; or under proper conditions, after the fishes reach the commodity specification, the whole net cage is dragged to a wharf nearby a city, so that the live fishes are conveniently listed in batches. In some large-scale net cage farms, the live fish transport ship can be directly driven to the position near the net cage for harvesting live fish, and the live fish transport ship has better maneuvering flexibility. In the aspect of daily management, the main work of cage culture after the fish fry is thrown in is to throw bait and change the net body.
The sea culture net cage floating in sea is cylindrical, has floating body in the upper end and net body in the lower part for fish culture. The net body is huge, and once a damaged place is not easy to detect, the damaged position is not easy to determine in time after the damaged place is detected.
Therefore, there is a need to develop a new marine culture cage and a marine culture method to solve the above problems.
