Abstract

The invention discloses a deep water cage device for preventing external biting fishes from attaching. The device includes a deep water cage device, a square cage device nested inside the deep water cage device, and a buffer device for junctions of a circular deep water cage frame and a square deep water cage frame. Two-layer mesh arrangement is employed, the outer layer is covered with a large-mesh net and hung on the circular deep water cage frame for protection, the inner layer is the mesh net suitable for the size of fishes cultured in cages and is mainly used for protecting and isolatingfish schools, the double-layer mesh net mainly achieves protection through physical isolation, not only can the biting fishes be effectively prevented from directly attacking the inner-layer net, butalso can prevent the long-nosed needlefishes from catching the fishes in the net, through the buffer device, the impact force of inner side walls of the square deep water cage frame and the circular deep water cage frame is alleviated, moreover, the deep water cage device and the square cage device are effectively protected, and protection of the device is improved.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a deep-water cage device for preventing external biting fish from attacking. Background technique [0002] The Sansha waters are far away from the land, and the traffic is highly restricted. The investment, operation and management costs of deep-water cage culture are relatively high. Compared with the crowded offshore cage culture area, the 10-30m isobath in the Sansha sea area is basically undeveloped. The water quality here is excellent, with an annual average water temperature of 28°C and a relatively high accumulated temperature. From the perspective of cost, the Sansha sea area generally breeds high-quality fish with high value, such as leopard spiny perch, humpback perch, tiger spot and oval pomfret broodstock and other high-value fish. However, there are a large number of dangerous fish in the South China Sea. The most species of dangerous fish are biting fish, main...
