Abstract

A high-efficiency fishing net for fresh-water bottom fish belongs to the technical field of aquatic product culturing and catching. The aim of the utility model is to provide the high-efficiency fishing net for fresh-water bottom fish, which is composed of the following components: a fish containing net cage with an opening at one surface, and a fish repelling net. The high-efficiency fishing net for fresh-water bottom fish is technologically characterized in that: the fish containing net cage 1 and the fish repelling net 3 are made of fishing net material; the meshes are in a range 1.0-3.0cm; an opening of the fish containing net cage 1 is provided with a tongue net 2; a steel bar iron chain with a diameter of 4-5mm is used as a sinker; foam float balls with diameters of 6-10cm is adopted as floats of an upper edge 4 of the fish repelling net 3; the steel bar iron chain with the diameter of 4-5mm is adopted as the sinker of a lower edge 5 of the fish repelling net 3; and the ratio between the length of the upper edge and the length of the lower edge is 80-90:100. and a net sleeve 6 is provided at a connection part between the net cage 1 and the fish repelling net 3 so as to be penetrated by a bamboo pole for fixedly connecting the fish containing net cage 1 and the fish repelling net 3. According to the fishing net, not only are small number of fishing times and high efficiency obtained, but also the high-efficiency fishing net for the fresh-water bottom fish has the following advantages: low labor force cost, capability for fishing at any time along with sealing, simple structure, high practicability and easy popularization.

Description

The efficient catching net of a kind of fresh water fish on bottom layer

Technical field

The utility model relates to the efficient catching net of a kind of fresh water fish on bottom layer.

Background technology

At present,, mainly adopt the catching net and the method for traditional type, draw in the net, need 8～10 people to operate usually as common for fishing for of fish on bottom layers such as yellow cartfish, mandarin fish, crucian, not only time-consuming consumption power, labor cost is high, and it is low to work the rate of catching, and effect is undesirable.In the process of fishing for, make fish on bottom layer injured easily, cause the low and appearance poor of transportation survival rate, influence its commodity value.

Summary of the invention

The purpose of the utility model is in order to overcome the deficiency of conventional fish catching net, to provide a kind of fresh water fish on bottom layer efficient catching net.This netting gear not only can be saved a large amount of labor costs, and two to the three net rates of fishing for reach more than 95%; And be that the shoal of fish is driven back trip network access case automatically in the process of fishing for, avoided mutual collision and friction, make the damage of fish body minimum.

The technical scheme that the utility model adopts is, the efficient catching net of a kind of fresh water fish on bottom layer, comprise by the Sheng fishnet case of one one end opening with catch up with fishnet to constitute.Its technical characterictic is, contains the fishnet case and catches up with fishnet to adopt the fishing net material to process, and mesh size is 1.0～3.0cm, contains the long 1000～1500cm of fishnet case, wide 200～300cm, high 150cm.Catch up with the headline of fishnet to use the foam ball float to make float, floating ball diameter 6cm～10cm, spacing 25cm; Infraclass is used and is installed bar diameter Φ 4～5mm whole piece iron chains additional as sinker, and headline is 80～90: 100 with the length ratio of infraclass, and catching up with the fishnet height is 500～700cm, and length is equal to or greater than the fish pond length of being fished for.

The technique effect of the utility model is: it is few to have a number of times of fishing for, and catching rate is high; The low characteristics of fishing at any time of labor cost with sale at any time.

Embodiment

As shown in Figure 1, the Sheng fishnet case 1 long 1000～1500cm of the efficient catching net of fresh water fish on bottom layer, wide 200～300cm; High 150cm; Adopt the fishing net material to process, mesh is 1.0～3.0cm, the edge of opening tongue net 2 adopt bar diameter be 4～5mm iron chains as sinker; Make it closely to contact, do not interspace with water-bed.Catching up with fishnet 3 to adopt mesh is that 1.0～3.0cm fishing net net sheet is processed, and 4 use diameters, 6～10cm foam ball float of raising to the higher plane of principle is made float, spacing 25cm; Infraclass 5 use bar diameters be 4～5mm iron chains as sinker, last infraclass length ratio is 80～90: 100.Catching up with fishnet 3 net 6 to be set with containing fishnet case 1 junction, insert the bamboo bar, be convenient to closely connect net cage 1 fast and catch up with fishnet 3.

During use, will contain fishnet case 1 earlier and be erected at limit, port, the pool, with the bamboo timber with netting gear fixing after, again tongue net 2 is tiled in the pond forward at the bottom of.Simultaneously place, the slit between net cage 1 and bank is provided with block, prevents that fish from fleeing from from this slit; To catch up with an end of fishnet 3 to be connected with bamboo pole and fix, will catch up with fishnet 3 to be disposed to the limit, pond again along net cage 1 a back of the body mouthful one side with net 6 with net cage 1 opening one side; 2-4 people pulls on the coast and catches up with fishnet 3 other ends, only pulls on an end of guiding principle 4, along one week in the pool, fish is arrived in the waters near net cage 1, and dwindle the ring of encirclement gradually lentamente.In the time of near headline 4 is pulled to net cage 1, slams infraclass 5 and begin to receive net, receive again and raise to the higher plane of principle 4, gradually fish is rushed to 1 li in net cage, pack up tongue net 2, so far fish for end.
