Embodiment Construction

[0012] refer to figure 1 , figure 1 It is a three-dimensional schematic diagram of a single net cage of the present invention, from figure 1 It can be seen that the specific structure of the present invention includes net cage 1, net outline 2, buoy 3, and specific technical scheme: a double-layer net is respectively arranged on the four sides and the bottom surface of the net cage 1, and the inner layer of the double-layer net Be big eye net 4, outer layer is small eye net 5 (this double-layer net only draws the side of front among the figure, and the double-layer net of its back, left side, right side and bottom surface is not drawn among the figure). This double-layer net, the mesh of the big eye net 4 of inner layer is 20-60 millimeter, and the mesh of outer layer small eye net 5 is 5-15 millimeter. Above net outline 2, buoy 3, also be provided with protective fence 6 around net cage 1, purpose is to prevent fish from jumping out from net cage.

Abstract

The invention discloses an aquaculture net cage with double-layer nets. The aquaculture net cage comprises net cage bodies, a net line and float bowls and is characterized in that the corresponding double-layer net are respectively arranged on the periphery and the bottom surface of each net cage body; the inner layer of each double-layer net is a large-mesh net and the outer layer of each double-layer net is a small-mesh net; protective guards are also arranged above the net line and the float bowls and on the periphery of each net cage body; an isolating net between two or more connected net cage bodies is a large-mesh net. The aquaculture net cage disclosed by the invention is simple in structure and easy to manufacture and has the advantages that juvenile fish to big fish can be cultured in one net cage without replacing the net cage, so that feeds for fish are saved, the net cage culture cost is reduced, the water pollution outside the net cage is reduced, and the aquaculture net cage is convenient to manufacture.

Description

[0001] technical field [0002] The invention relates to a culture cage with double-layer nets, which belongs to the technical field of fish culture. Background technique [0003] In rivers, lakes and seasides, the use of net cages for fish farming has developed rapidly and has become a way for people to get rich. [0004] The current cage culture uses single-layer fishnets or nets made of other materials to enclose 1.5-2 meters below the water surface for fish culture; cage culture starts from young fish and grows to a few kilograms. Sale. When raising juvenile fish, the mesh of the cage is small and the wires are thin. When the fish grow up, it is easy to quilt the net. Therefore, when the fish grow to about 0.5 kg, they have to be replaced with cages with large mesh and thick wires for breeding. This conventional method has the following disadvantages: the one is that it is troublesome to replace the net cage, and the growth of the fish is frightened; , increasing the...
