Abstract

The utility model provides a netting gear for catching fish in slow flow. Net cloth is installed on an inlet frame of the netting gear. Square skeletons are arranged in the net cloth at the back of the inlet frame. Annular skeletons are installed at the back of the square skeletons. A separation net is installed on the middle portion of the inlet frame. The top portion of the separation net is connected with the square skeletons. The separation net and the net cloth on the right side form a right channel, and the separation net and the net cloth on the left side form a left channel. Inner space of a net body of the netting gear is large, injuries to caught fish samples are small, the fish is not injured, operation is convenient, and the fish can be quantitatively collected day and night.

Description

A kind of unhurried current is fished for the netting gear of fish

Technical field

The utility model relates to fishing gear, netting gear field, specially refers to the netting gear that a kind of unhurried current is fished for fish.

Background technology

Gather, investigate and study by the fish to waters such as rivers and lakes reservoirs, can assess quantity or the stock number of fish population, significant for fish production and the protection of fish resources.Fish for used netting gear in the at present fish production and mainly contain trawlnet, drift net, set net etc., netting gear uses and is generally used by professional fisherman, operation has certain craftsmenship, and the operating location of described netting gear mostly is the swift running water habitat, and fish are fished in the water ecological environment border that generally is not suitable for flowing slowly.

Summary of the invention

The purpose of this utility model is to provide a kind of passage that utilizes limit net and separation net to consist of, and the netting gear that the unhurried current in the catching net is fished for fish is advanced in the trip that fish are preserved from.

For achieving the above object, the technical solution of the utility model is:

A kind of unhurried current is fished for the netting gear of fish, comprise ring skeleton, screen cloth, quadrate framework, separation net and import framework, on the import framework of this netting gear screen cloth is housed, in the screen cloth at import framework rear quadrate framework is housed, ring skeleton is equipped with at the rear of quadrate framework, and separation net is equipped with at the middle part of import framework, and the top of separation net is connected with quadrate framework, separation net and the right net consist of right passage, and separation net and left side net consist of left passage.

Good effect of the present utility model is:

1, this netting gear scientific structure is simple, under the effect of flowing water and backstop, makes fish trip network access case afterbody;

2, the inner space of body is larger, and is little to the fish sample injury of catching, and fish are preserved from;

3, easy to operate, quantitative collection fish round the clock;

4, cheap, operating cost is cheap, the operation mobility strong.

Description of drawings

Fig. 1, unhurried current are fished for fish netting gear structural representation.

Embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing 1.

Referring to Fig. 1, length according to screen cloth 2, determine to pack into the quantity of the ring skeleton 1 in the screen cloth 2, again according to the size of fishing for fish, determine the distance between import framework 6 and the quadrate framework 3, separation net 4 is installed to the centre of quadrate framework 3 and import framework 6, then mounted netting gear is put into water, fish are swum in the network access tool, so that the required fish of quantitative collection with the right passage of the right net 5 formations with by the left passage that separation net 4 and left side net 7 consist of via separation net 4 along flowing water.

Claims

1. netting gear that unhurried current is fished for fish, comprise ring skeleton (1), screen cloth (2), quadrate framework (3), separation net (4) and import framework (6), it is characterized in that being equipped with on the import framework (6) screen cloth (2), in the screen cloth (2) at import framework (6) rear quadrate framework (3) is housed, ring skeleton (1) is equipped with at the rear of quadrate framework (3), separation net (4) is equipped with at the middle part of import framework (6), the top of separation net (4) is connected with quadrate framework (3), separation net (4) consists of right passage with the right net (5), and separation net (4) consists of left passage with left side net (7).
