Description

Technical Field

[0001] The utility model relates to the technical field of fish, in particular to a breeding cage. Background Art

[0002] Existing aquaculture cages are often equipped with bottom nets. For river basins with sand and gravel at the bottom, the bottom nets of the aquaculture cages will rub against the sand and gravel at the bottom under the reciprocating fluctuations of the water flow, causing the bottom nets to be damaged, and then the cultured organisms escape from the aquaculture cages, reducing the aquaculture yield.

[0003] Currently, there is a lack of a culture cage structure that can prevent the bottom net from being damaged by friction with the hard base of sand and stone. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a bottomless aquaculture cage, which has solved at least one of the above-mentioned technical problems.

[0006] The inner net and the separation part of the outer net are both connected with ballast chains;

[0007] The separation part of the inner net and the outer net is covered with a riprap ballast layer formed by stacking riprap, the riprap ballast layer covers the ballast chain, and the riprap ballast layer is covered with a sandbag ballast layer formed by stacking sandbags.

[0008] The utility model omits the bottom net of the cage by optimizing the structure of the aquaculture cage, and greatly improves the fixing effect of the separation part of the net at the bottom by optimizing the structure of the net, combining the ballast chain, the riprap ballast layer and the sandbag ballast layer, thus avoiding the wear caused by the friction between the bottom of the aquaculture basin and the net.

[0009] Further preferably, the length of the separated portion of the inner net garment extending inwardly is 2 m;

[0010] The length of the separated portion of the outer net garment extending outward is 2m.

[0011] Further preferably, two ballast chains arranged side by side are connected to the separation parts of the inner net and the outer net.

[0012] Further preferably, the overlapping portion of the inner net garment and the outer net garment is connected by a basalt fiber line.

[0013] Further preferably, the basalt fiber wire braided layer has a braided mesh structure.

[0014] Further preferably, the cage frame comprises a U-shaped frame, and a walking pedal is connected to the opening of the U-shaped frame;

[0015] The U-shaped frame is connected to the top of the net garment;

[0016] The walking pedal is installed on the shore base;

[0017] The net is arranged in a U shape and is connected to the shore base to form a closed structure.

[0018] It is convenient to walk on the pedal to observe the activities of the aquaculture organisms near the shore. The Chinese sturgeon and other organisms like to spawn near the shore. It is convenient for observation.

[0019] Further preferably, a side of the net contacting the shore is connected with a side rail, and the top of the side rail is connected to an anchor rod fixed to the top of the shore through an anchor chain;

[0020] The side rails are closely attached to the shore foundation by at least three anchor rods passing through the side rails and the shore foundation.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The utility model omits the bottom net of the cage by optimizing the structure of the aquaculture cage, and greatly improves the fixing effect of the separation part of the net at the bottom by optimizing the structure of the net, combining the ballast chain, the riprap ballast layer and the sandbag ballast layer, thus avoiding the wear caused by the friction between the bottom of the aquaculture basin and the net.
