Description

A high-efficiency fishing net for freshwater bottom fish

technical field

The utility model relates to a high-efficiency fishing net for freshwater bottom fish. the

Background technique

At present, for the fishing of bottom fish such as yellow catfish, mandarin fish, and crucian carp, traditional fishing nets and methods are mainly used, such as ordinary pulling nets, which usually require 8 to 10 people to operate, which is not only time-consuming and labor-intensive, but also has high labor costs. , and the catch rate is low, the effect is not ideal. It is easy to injure the bottom fish during the fishing process, resulting in low survival rate and poor appearance during transportation, which affects its commodity value. the

Contents of the invention

The purpose of the utility model is to provide a high-efficiency fishing net for freshwater bottom fish in order to overcome the shortcomings of the traditional bottom fish fishing net. The net gear can not only save a lot of labor costs, the fishing rate of two to three nets can reach more than 95%; moreover, in the fishing process, the fish will be driven away and then automatically swim into the net cage, avoiding mutual collision and friction, which will damage the fish body minimum. the

The technical solution adopted by the utility model is that a net gear for freshwater bottom fish high-efficiency fishing is composed of a net box for containing fish and a net for catching fish with an opening at one end. Its technical feature is that the fish holding net box and the fishing net are made of fishing net materials, the mesh size is 1.0-3.0cm, the fish holding net box is 1000-1500cm long, 200-300cm wide, and 150cm high. The upper line of the fishing net uses foam floats as floats, with a diameter of 6cm-10cm and a spacing of 25cm; the lower line uses a whole iron chain with a diameter of Φ4-5mm as a sinker, and the length ratio of the upper line to the lower line is 80 ~90:100, the height of the fishing net is 500~700cm, and the length is equal to or greater than the length of the fish pond to be caught. the

The technical effect of the utility model is that it has the characteristics of less fishing times, high fishing efficiency, low labor cost, and can be sold at any time and fished at any time. the

Detailed ways

As shown in Figure 1, the fish-holding cage 1 of freshwater bottom fish high-efficiency fishing nets is 1000-1500cm long, 200-300cm wide, and 150cm high. The edge of department net 2 adopts steel bar diameter to be that 4～5mm iron chain is used as sinker, makes it closely contact with the bottom of water, does not stay gap. Fishing net 3 is made of fishing nets with a mesh size of 1.0-3.0 cm. Upper class 4 uses foam floats with a diameter of 6-10 cm as floats with a distance of 25 cm. Lower class 5 uses steel chains with a diameter of 4-5 mm. As a sinker, the length ratio of the upper and lower strands is 80-90:100. Net cover 6 is set at catching fish net 3 and Sheng fish net cage 1 junction, inserts bamboo pole, is convenient to connect net cage 1 and catch fish net 3 tightly fast. the

During use, the fish-filled net cage 1 is erected on the bank of the pond mouth earlier, after the net gear is fixed with bamboo stakes, the tongue net 2 is laid forward on the bottom of the pond. At the same time, a block is set at the gap between the net cage 1 and the bank to prevent fish from escaping from the gap; one end of the fishing net 3 is connected with the net cover 6 on one side of the net cage 1 opening with a bamboo pole and fixed , and then arrange the fishing net 3 along the back of the net cage 1 to the pond; 2-4 people drag the other end of the fishing net 3 on the bank, and only pull the end of the upper line 4, slowly along the pond for a week, and drive the fish To the waters near cage 1, and gradually narrow the encirclement. When the last key link 4 was pulled near the net cage 1, step on the lower key link 5 and start to collect the net, then receive the upper key link 4, and gradually fish will be rushed to the net cage 1 li, and the tongue net 2 will be put away, so far the fishing is over. the
