Description
The utility model relates to a kind of fishing net, relates in particular to a kind of fish on bottom layer of fishing for fish on bottom layer and draws in the net.
At present, the pond fish on bottom layer is fished in the north, the general disposable way of cleaning up the pond in winter that adopts, promptly first fish has at the middle and upper levels caught, again water is drained, under the people in the pond with hand or drag for the sea and arrest, so not only wasted a large amount of water,, and the bottom unblemished fish is concentrated listing, the influence person's of breeding fish economic well-being of workers and staff.The employing haul seine is fished for, also can only catch fish at the middle and upper levels, cooperate " HHZ impulse generator " to shock by electricity, need water temperature below 8～10 ℃ the time, just can catch the part fish on bottom layer, be equipped with such cover net and power consumption expense and need about 5,000 yuan altogether, and draw once net to need 12～14 people with the labour, little and specialist are too high with this method cost.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of simple in structure, volume is little, cost is low, and is easy to use, in raising together with the pond, use do not damage in, upper strata fish and juvenile fish, rise and catch the rate height, labor intensive is few, all can use throughout the year, is exclusively used in the bottom fishnet of fishing for fish on bottom layer.
The purpose of this utility model can reach by following measure:
A kind ofly fish for drawing in the net of fish on bottom layer, comprise barrier net, the barrier net upper edge is provided with the rope of raising to the higher plane of principle, the rope of raising to the higher plane of principle is provided with uniform float, its special character is: described barrier net bottom is provided with the fish gathering pocket, along joining with barrier net, the infraclass rope is through on barrier net lower edge and the fish gathering pocket mouth outer in the fish gathering pocket mouth, and the infraclass rope is provided with uniform sinker.
Fish gathering pocket of the present utility model can be the vertebra shape string bag.
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to accompanying drawing, the utility model top is the barrier net 3 that fish uses of blocking, and its upper edge is installed with the rope 2 of raising to the higher plane of principle, and the rope 2 of raising to the higher plane of principle is provided with uniform float 1, is used for making the retaining fishnet 3 floating water that stand on.Along joining, infraclass rope 4 is through on the pocket mouth outer of the lower edge of barrier net 3 and fish gathering pocket 6 in the pocket mouth of barrier net 3 bottoms and vertebra shape fish gathering pocket 6, and infraclass rope 4 is provided with uniform sinker 5, is used to make the lower edge of barrier net 3 to be sunken to and water-bedly is adjacent to ground.Float 1 can adopt polyethylene vacuolar membrane ball or plastic hollow rhombus float in the utility model; Sinker 5 can adopt the plumbous angle of rhombus; The count of barrier net 3 should be greater than the count of fish gathering pocket 6, so as when fishing, to catch stay greatly little.Fish gathering pocket 6 also can adopt other little shape of mouthful big end, and its end should guarantee that fish can not turn round.During use, it is suitable earlier the utility model to be placed on pool side expansion pendulum, and fish gathering pocket 6 pocket mouths are towards direction of advance one side.Behind the following water, the rope 2 of raising to the higher plane of principle is preceding, infraclass rope 4 after, make the utility model in water, become an inclined plane.Rope 2 is stressed big owing to raise to the higher plane of principle, and infraclass rope 4 is stressed little, and because of the utility model is heavy net, so barrier net 3 lower edges and fish gathering pocket 6 drag mud and do not roll mud, fish gathering pocket 6 pocket mouths are opened again.
The utility model compared with prior art has following advantage:
1, simple in structure, volume is little, and cost is low, and is easy to use.
2, according to bottom fish, as: the life characteristics design of carp etc., harvesting rate height.
3, in raising together with the pond, use do not damage in, the upper strata fish.
4, labor intensive is few, all can use throughout the year.
