Abstract

The utility model belongs to fishing gear used for catching fish in water, in particular to a single-layer and three-layer overlapping barbed fishing net which has many sticklebacks and can stab fish of four sizes and sizes. The mesh net (3), the bottom net (7) and the net pendant (8), are characterized in that a middle net (4) is arranged between the upper net (2) and the bottom net (9), and the middle net (4) overlapping with the bottom net outline (7) is connected with middle layer to be small mesh net (6), and small mesh net (6) is made pocket shape (9), and both sides layer is big mesh net (5), and this Compared with the single-layer single-piece gill net with the same area, it can stab fish of three different sizes without changing fishing gear. There are more fish and the fishing efficiency can be increased by more than three times; it has a good effect on cleaning aquaculture water and is beneficial Artificial farming of aquatic products.

Description

Single-layer triple-layer gillnet

technical field

The utility model belongs to a fishing gear used for catching fish in water, in particular to a single-layer three-layer overlapping barbed fishing net which has many barbed fish and can stab fish of four sizes.

Background technique

At present, the fishing gear used by people to catch fish in the water all adopts a single-layer single-piece gill net, and a gill net with the same area is used, so that the gill fish is less, the fishing efficiency is low, and only one type of fish can be caught. It is troublesome, time-consuming and costly to change the fishing net for the fish of the standard. In addition, when breeding in reservoirs and lakes, it is necessary to clean up the water body in advance, especially to exterminate all wild fish and animals in the water, otherwise these wild animals and wild fish will cause damage to the reared fry and aquatic products, seriously affecting the breeding benefit.

Contents of the invention

The purpose of the utility model is to overcome the above technical deficiencies, and provide a single-layer three-layer overlapping barbed net with many sticklebacks and high efficiency for catching fish of four sizes.

The technical scheme adopted by the utility model to solve the technical problem is: a single-layer three-layer overlapping barbed fishing net composed of floats, net nets, middle nets, bottom nets and net pendants. There is a middle net in the middle, and the middle net and the bottom net are overlapped and connected, and the middle layer is a small mesh net, and the small mesh net is made into a net bag, and the two sides are large mesh nets.

The beneficial effects of the utility model are: compared with the single-layer single-piece barbed net with the same area, the barbed net can stab three kinds of fish of different sizes without changing the fishing gear, and there are many stabbed fish, and the fishing efficiency can be increased by more than three times; for cleaning Aquaculture water, the effect is good, is conducive to the artificial breeding of aquatic products.

Detailed ways

With reference to the accompanying drawings, a single-layer three-layer overlapping gill fishing net is composed of a float 1, an upper mesh 2, a middle mesh 3, a bottom mesh 7 and a net pendant 8, and is characterized in that there is a gap between the upper mesh 2 and the bottom mesh 8 There is a middle net 4, and between the middle net 4 and the bottom net 7, the middle layer is overlapped and connected with a small mesh net 6, and the small mesh net 6 is made into a net pocket 9, and the two layers are large mesh nets 5; The net net 2 is connected, the net net 3 is connected between the net net 2 and the middle net net 4, and the net pendant 8 is fixed on the bottom net net 7.

The net gear is equipped with three nets of different specifications, so when fishing, it can fish three kinds of fish or aquatic products with a small mesh net of 6 or more sizes at the same time, which is especially suitable for fishing operations with rapid currents and large water areas. It is suitable for fishing in oceans, lakes, reservoirs, fishponds and rivers, with high efficiency, large catches and many varieties.

Claims (1)

1, a kind of individual layer three plies thorn fishing net, weighing down (8) by cursory (1), the last head rope (2), middle order net (3), spacer screen guiding principle (7) and net forms, it is characterized in that being provided with the middle head rope (4) between the head rope (2) and the spacer screen guiding principle (9), the overlapping intermediate layer that is connected with is small-eyed net (6) between the middle head rope (4) and spacer screen guiding principle (7), small-eyed net (6) is made pocket shape, and two boundary layers are big-holed net (5).
