Background art:
the deep water net cage is a large net cage with the water depth of more than 15 meters and open water areas along the sea. The deep water net cage has larger culture capacity, and is a marine culture facility with stronger wind wave resistance and ocean current resistance. The deep water net cage has obvious advantages in the aspects of expanding the culture sea area, reducing the pressure of the coastal environment, improving the quality of cultured fish, increasing the culture benefit and the like. A conventional deepwater net cage generally has a circular frame body, and a net is disposed under the frame body. The net cage for cultivation is placed in seawater for a long time and is easily attached by some organisms, so that the weight of the net cage is increased, meshes are blocked, smooth water flow is blocked, the exchange of water bodies inside and outside the net cage is influenced, the pressure of a net coat is increased, even the net coat is abraded, the fish body is abraded, the growth of fish is influenced, and the cultivated fish is damaged. In daily management, the fish cage is cleaned frequently according to the attachment condition of the cage and the quantity of fish in the cage. The cleaning work is very difficult, the manual work is needed to submerge into the water bottom for operation, and the cleaning effect is not good. In order to ensure that the water flow is smooth and remove attachments attached to the net and the fish body growth needs, the net needs to be replaced at proper time, the meshes are enlarged, and the water exchange between the inside and the outside of the net cage is improved. When the net is replaced, the old net is firstly separated from the other half, the new net is placed into the frame, the net is tied from the empty half, only the opposite side is reserved, the old net is moved into the new net, the old net is pulled up, and the fish swims into the new net. Because the deepwater net cage has a large number of big fish, special care should be taken during operation, and particularly, the fishnet is prevented from being wrapped by the net to cause scratches or oxygen deficiency.
The invention content is as follows:
the invention aims to provide a horizontal deep-water aquaculture net cage to achieve the purposes of preventing net clothes meshes from being blocked and avoiding cultured objects from being scratched or lack of oxygen caused by net replacement.
