The utility model is characterized in that: the fishing net consists of three layers of webbing, the central webbing layer is a dense webbing with a mesh size between 6 and 16 cm, and the two side webbings are sparse webbings with mesh size between 20 and 60 cm. The utility model has simple structure, the mesh of the dense webbing and the sparse webbing are optimized, having the best fishing effect. Therefore, the utility model can be used for catching fish, effectively preserving the baby fishes and being a fishing net which catches fish selectively.
Description
Technical field
The utility model relates to a kind of fishing net of fishing usefulness.
Background technology
Present fishery mainly is to use common individual layer net, and this class net is owing to having only one deck, and is thin as mesh, when fishing for, catches juvenile fish easily, destroys the fishery resources breeding; Bigger as mesh, when fishing for, fish defies capture.And the fish that captures also might be on the net stuck, and survival rate is low, damages net easily.Mesh is too little to cause double ill effect of catching again, and can only be suitable in Xi Zhou, shoal and river.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of fresh aquatic food gill net, can reach the effect of fishing for the high-quality adult fish.
The purpose of this utility model is achieved in that a kind of fresh aquatic food gill net, comprise the head rope and fish for net, it is characterized in that: the described net of fishing for is made up of the three-layer network sheet, and the middle level is that size of mesh is 6 to 16cm close net sheet, and both sides are that size of mesh is 20 to 60cm thin net sheet.
Described close net sheet developed area is greater than thin net sheet.
In the described head rope, wherein a side is provided with float, and opposite side is provided with plummet.
The utility model is simple in structure, the size of mesh of dredging net and close net is through optimal design, can reach best fishing efficiency, when fishing for, list can capture fresh and alive fish, also can allow juvenile fish freely pass through, and has overcome common fishing net to the double deficiency of catching of juvenile fish resource, be a kind of fishing net tool that carries out selective fishing, be applicable to ocean deep sea fishing operation.The beneficial effects of the utility model are: (1) is rational in infrastructure; (2) protect the juvenile fish resource effectively; (3) further improved the quantity of the catch and the fresh and alive rate of seizure of fishing for; (4) applied widely, can be used for ocean deep sea fishing operation; (5) easy operating.
Description of drawings
Fig. 1 is a Facad structure schematic diagram of the present utility model;
Fig. 2 is construction profile of the present utility model (user mode).
Embodiment
Below in conjunction with the drawings and specific embodiments this practicality is further specified.
As shown in Figure 1, the utility model is a kind of fresh aquatic food gill net, comprises float 1, fishes for net, plummet 4 and the upper and lower head rope 5 by what skin dredged that net sheet 2 and the close net sheet 3 in middle level form.
Fish for net and be made up of the three-layer network sheet, the size of mesh of net sheet designs respectively in the reasonable scope, and the middle level is close net sheet 3, and its mesh 6 is of a size of 6 to 16cm, and close net sheet 3 both sides are to dredge the net sheet, and its mesh 7 is of a size of 20 to 60cm.Close net sheet 3 developed areas are greater than dredges net sheet 2, and close like this net sheet 3 just can be dredged in the net sheet 2 at skin and form mesh bag 8 one by one.
The both sides up and down of fishing for net are pricked the head rope 5 up and down, and the last head rope 5 is provided with float 1, makes on whole fishing net orientation bubbles through the water column, and the following head rope 5 is provided with plummet 4, makes whole fishing net perpendicular to the state that keeps expansion in the water.The size of the head rope, the size of float can be regulated with the position with the weight of position, plummet and be cooperated fishing net work.
The fisherman launches as long as hold the head rope 5 in use, and connected fishing net also and then launches.Come from the front as fish, can not pass the fish of dredging mesh 7 in the net sheet 2 and just be stuck on the mesh 7 of dredging net sheet 2 and can not get away; In the time of can passing the mesh 7 of dredging net sheet 2, fish also can be blocked by the mesh 6 of close net sheet 3, because fish is by the light of nature to preshoot, close net sheet 3 is protruded from the mesh 7 of dredging net sheet 2, just formed mesh bag 8 (as shown in Figure 2) one by one, fish can only ceaselessly struggle in the mesh bag 8 that is formed by close net sheet 3, is difficult for again running out of, and also can not lived by network interface card.The mesh 7 that wherein dredge in the net sheet 2 on one side this moment plays the effect of tightening up mesh bag 8, and 7 of the meshes of the thin net sheet 2 of another side play auxiliary close net sheet 3 and stop the effect of fish to preshoot.Fish is come from the back side of net, and above effect is arranged equally.Whole net seems that the fish littler than mesh 6 sizes then can pass freely through each net sheet, thereby reach selective fishing as various " mesh bag " arranged, and effect can protect fishery resourses.
