[0002] Crayfish is a delicacy on our table. Nowadays, the market demand for crayfish is very high, so a large number of crayfish farms are needed to breed crayfish in order to meet the market demand and enable breeders to obtain certain profits. Breeding farms generally breed crayfish in closed enclosures for easy management and easy catching.

[0003] The closed enclosure culture of crayfish requires safe and reliable enclosures. Currently, crayfish farming fences are mainly made of woven nets. Crayfish will crawl out along the fences, which can easily cause holes in the fences after long-term use. It is difficult to replace the fences, and the crayfish will escape through the holes, causing certain losses to the farming. Utility Model Content

[0006] The effect achieved by the above components is: the fence can be installed in a surrounding shape in the breeding pond through the corner posts and anchors, wherein the fence can be assembled and connected with the slots on the corner posts in conjunction with the inserts, which is convenient for later replacement. In addition, the stop strips can prevent crayfish from climbing and escaping.

[0007] Preferably, the locking member includes a rotary plate, a rotary handle is fixed to the back side of the rotary plate, a stud is fixed to one side of the rotary plate, and a screw hole adapted to the stud is opened on the back side of the stop strip.

[0008] The effect achieved by the above components is that the stud on one side of the rotary vane can be driven to be screwed into the screw hole by twisting the rotary handle, and the stop strip is fixed by the rotary vane, which facilitates assembly.

[0009] Preferably, the anchoring member comprises an anchor rod fixed to the bottom end of the corner column, and a plurality of convex rings are fixed to the outer side wall of the anchor rod.

[0010] The effect achieved by the above components is that they can be inserted into the breeding pond through the anchor rod and the convex ring to perform the anchoring and positioning work of the corner column.

[0011] Preferably, a slope is provided on the outer side of the stop strip.

[0012] The effect achieved by the above components is that the climbing adhesion of the crayfish can be reduced through the inclined surface when the crayfish climbs.

[0013] Preferably, a convex block is fixed on the inner side of the corner column, a positioning column is fixed on the convex block, and a bottom net is fixed between the positioning columns.

[0014] The above components have the following effects: the bottom net can be assembled through the positioning posts on the protrusions, which is convenient for use.

[0015] The present invention provides a crayfish farming fence that prevents crayfish from escaping. Compared with the prior art, the present invention has the following improvements and advantages:

[0016] Firstly, the utility model can install the fence in a surrounding shape in the aquaculture pond through the corner posts and anchors, wherein the fence can be assembled and connected with the slots on the corner posts in conjunction with the cuttings, which is convenient for later replacement;

[0017] Second, the utility model can reduce the climbing adhesion of crayfish when they climb by using the inclined surface on the stop bar, thereby preventing the crayfish from climbing and escaping. BRIEF DESCRIPTION OF THE DRAWINGS
