Description
Technical Field
The invention belongs to the technical field of aquaculture, and particularly relates to a procambarus clarkia grading device for an aquaculture pond.
Background
In the comprehensive culture pond of rice and fish in China, the procambarus clarkii begins to throw seedlings in 3 late ten days, the phenomenon of batch feeding exists, the specifications of the seedlings are difficult to unify due to the growth difference of the procambarus clarkii, when some fast-growing individuals reach the specifications of commercial shrimps, the shrimps are usually caught and put on the market by a rotation catching and rotation putting method, when some lobsters in the aquaculture pond reach the market specification, fishermen put the ground cages into the pond, so that the procambarus clarkii with different sizes enter the ground cages together, and then separate the large lobsters from the small lobsters through manual sorting, because the fishing can cause stress reaction to the procambarus clarkii, the procambarus clarkii after artificial classification can be molted and is easily eaten or damaged by other procambarus clarkii, therefore, in order to improve the survival rate after the rotation capture, the small-sized procambarus clarkii needs to be put into another pond for continuous culture, and the large-sized procambarus clarkii comes into the market. This kind of artifical hierarchical mode, it is troublesome, and the human cost is high.
Disclosure of Invention
The invention aims to provide a procambarus clarkii grading device for an aquaculture pond, which can automatically grade procambarus clarkii by climbing away in a natural aquaculture pond. Solves the stress reaction of the artificial classification to the procambarus clarkia in the prior art.
The invention is realized by the following technical scheme:
the device comprises a grading inner net main body and a shell, wherein the shell is sleeved outside the grading inner net main body, and the maximum distance between the inner wall of the shell and a net of the grading inner net main body is more than 5 cm; the grading inner net body comprises a net and a support, the net is applied on the support and comprises a large net opening, a small net opening, a main net and a grading net, the support comprises a main body support, a large net opening support, a small net opening support and a grading net support, the main net is applied on the main body support, the large net opening is fixed on the large net opening support, the small net opening is fixed on the small net opening support, and the small net opening support is positioned in the grading inner net body and fixed on the main body support through a lifting rope; the netting is provided with a grading net opening, one end of the grading net is fixed on the grading net bracket, the grading net is fixed on the grading net opening of the netting through the grading net bracket, the other end of the grading net is a free end, and the grading nets are contracted together in a free state;
one end of the shell is closed, the other end of the shell is open, and the shell wall is provided with a water permeable hole; the aperture of the permeable hole is smaller than that of the grading net bracket.
Further, a circle of skirt net is arranged on the large net opening support, one end of the skirt net is fixed on the large net opening support, the other end of the skirt net is provided with an elastic end, and in a use state, after the grading inner net main body is sleeved into the shell, the skirt net is sleeved on the shell.
Further, the mesh and netting of the skirt mesh is much smaller than the minimum size of the procambarus clarkii to be classified.
Further, the size of the classification net support is set according to the specification of the procambarus clarkia to be selected.
Furthermore, the grading nets are arranged on the upper, left and right 3 surfaces of the outer wall of the netting, the grading nets are only left to be attached to the lower surface of the inner wall of the shell, the grading nets are not arranged, and the arrangement density of the grading nets is 1-2/100 cm2。
The design principle of the invention is that after the procambarus clarkii in the culture pond enters the grading inner net body through the small net opening, the procambarus clarkii is difficult to escape from the small net opening due to the arrangement of the small net opening, the procambarus clarkii is adhered to the inner wall of the net cover, and the small-sized procambarus clarkii escapes from the grading net opening and enters the gap between the shell and the grading inner net body. When the number of the procambarus clarkii in the device reaches a certain number, the inner grading net main body is lifted, the large-size procambarus clarkii is left in the inner grading net main body, the small-size procambarus clarkii is left in the outer shell, the small-size procambarus clarkii is poured into another culture pond, and the large-size procambarus clarkii is sold on the market. The invention reduces the manpower grading cost and lightens the damage to the small-size procambarus clarkii.
