Abstract
A subglacial classified fishnet relates to lake fishing tool technical field in north at winter, while prior winter traditional fishing tool uses subglacial large draw net, which can only mixed pick fish, but can not separate large fish and small fish, and separate different fish species, therefore, prior art can not protect demanded fish pieces. The utility model is characterized in that one net layer is arranged based on large draw net, to be drawn by an upper block, a middle block and a lower block, while the buoyant force of the floater of the upper block is lower than the gravity sum of the sinkers on the middle and lower blocks, the sinker gravity of the middle block is lower than the buoyant force of the floater of the upper block, the height between the middle and lower blocks is 20-40cm, the heights of the middle and upper blocks can be adjusted according to the depth of lake. The utility model can separate and pick up different fish species according to different habits.
Description
Technical field
The utility model relates to Fishing tool in winter field, northern lake.
Background technology
Tradition fishing net in winter is the subglacial haul seine, can only mix and fish for, and big fish small fish can't be separated and fish for, can't the fingerling that some is different separate and fish for, and can't protect many precious fingerlings, thus the destruction of causing fishery resources.
Summary of the invention
The utility model purpose is: a kind of netting gear is provided, it has changed the mixing of traditional haul seine formula and has fished for, on the basis of haul seine, wing lattice and keed have increased one deck etting respectively, be divided into two-layer up and down, the upper strata mesh is little, fish for little fingerling (belonging to the little whitefish of upper strata fingerling etc.), lower floor's mesh is big, fish for the big fingerling (carp that belongs to the bottom fingerling, catfish etc.), and traditional haul seine mesh is greatly the little fingerling in upper strata that can't fish for needs, mesh hour, then the precious juvenile fish that the little fingerling in upper strata and bottom are not developed into is together salvaged in keed and can't put in a suitable place to breed, has caused the significant wastage of limited aquatic resources.
The technical solution of the utility model is: on traditional subglacial haul seine basis, increase one deck etting again at left and right sides both wings face off the net; Three stalk ropes are arranged, and are respectively to go up stalk, middle stalk and stalk down, between last stalk and the middle stalk, middle stalk and control height of net opening with lifting rope respectively between following the stalk; Between last stalk and the middle stalk is the upper strata wing lattice, and height of net opening is determined by the depth of water; In the wing lattice of asking of stalk and following stalk into lower floor, height of net opening is the 20-40CM that makes progress from lakebed, this scope is big fingerling (belonging to the carp, catfish of bottom fingerling an etc.) scope of activities, this height is done suitable adjustment according to concrete enforcement environment.In stalk go up the buoyancy of the gravity sum of sinker with following stalk greater than last stalk float, middle stalk sinker gravity is less than the buoyancy of last stalk float, wing lattice can open for two-layer at subglacial to lakebed like this, the upper strata wing lattice is a small-eyed net, lower floor's wing lattice is a big-holed net, because little fingerling (belonging to the little whitefish of upper strata fingerling etc.) upwards moves about in the process of fishing for drawing in the net, big fingerling is distributed in the bottom in lake, and the big bottom of fish to the lake moves about in the process of fishing for.Wing lattice is divided into left wing's net and right flank net, and left wing's net is connected by keed with the right flank net is middle, and keed also is divided into two-layer up and down, and the upper strata is a small-eyed net, and lower floor is a big-holed net.Shared one deck small-eyed net clothing in the middle of big order keed and the little order keed.Shared one deck etting in the middle of big order wing lattice and the little order wing lattice, this etting is small-eyed net at leading portion for the big-holed net back segment, plummet is hung in the middle of the little order wing lattice of big order wing lattice of leading portion and back segment.Little fingerling in the bottom activity can be driven in the small-eyed net of upper strata like this.
Description of drawings
Fig. 1 is subglacial classification fishing net structural representation.
Fig. 2 is that Figure 1A is to schematic cross-section.
Embodiment
Draging stalk 1 length is 160M, diameter 45MM PEF rope is connected with fork rope 2, fork rope 2 straight warps are that 40MM is connected with a net bar 3, the upper, middle and lower of net bar 3 respectively with last stalk 4, middle stalk 5, obstruct 6 down and be connected, small-eyed net 10 big-holed nets 11 hang built in last stalk 4, middle stalk 5 respectively, obstruct on 6 down by 40% casing coupling rate, ask shared one deck etting in big-holed net and the small-eyed net, this etting leading portion 16 is a small-eyed net for big-holed net etting back segment, the lead that is hung in the middle of leading portion big-holed net and the back segment small-eyed net is restricted, and small-eyed net 10 meshes are that 3-6CM big-holed net 11 meshes are 8-10CM.Cursory 7 quality are 800g, middle stalk sinker 8 quality are 500g, under to obstruct sinker 9 quality be 600g, cursory 7, middle stalk sinker 8, down obstruct sinker 9 each 800 be evenly distributed in proper order by front and back and obstruct 4, middle stalk 5, obstruct on 6 down, last stalk 4, middle stalk 5, obstruct 6 for directly through the PEF stalk of 26CM down, obstruct down and add one on 6 directly through being the PEF rope of 5MM, the plummet of a 40g of every 20CM comes stalk 6 under the tractive on the PEF rope.Big-holed net 11 height of net opening are 20-40CM, but the actual depth of water of small-eyed net 10 network interface root a tree names control with lifting rope 12, the lifting rope diameter is 5-7MM.Utilize cursory 7 buoyancy that network interface is drawn back.Two wing lattices, centre added keed and form about this net divided, wing lattice and keed junction 13, and keed divides little order keed 14 big order keeds 15, little order keed 14 and big order keed 15 middle shared one deck ettings, etting is a small-eyed net, and little order keed 14 meshes are 2CM, and big order keed 15 meshes are 4-6CM.
