Abstract
The utility model discloses a kind of flowing water and gather fish sample device, comprise and be positioned at upstream and draw net in the upstream that " eight " word is arranged and be positioned at downstream and draw net in the downstream that just " eight " word is arranged, upstream is drawn net and downstream and is drawn the block that Netcom crosses both sides and be connected, and form fish gathering district in inside, upstream is drawn net and downstream and is drawn between net and be provided with filter, fish gathering is distinguished and is divided into and descending fish district and descending fish district by filter, upstream is drawn the upstream of netting the described descending fish district of formation remittance and is drawn lymphogranuloma inguinale, and lymphogranuloma inguinale is drawn in the downstream that the descending fish district of net formation remittance is drawn in downstream.The utility model forms fish gathering district by drawing net, makes the fish in up downstream introduce in netting gear smoothly, is difficult to flight; In "eight" shape draw net draw lymphogranuloma inguinale can according to the fish individual size of sample area adjustment width; A slice filter is used to enter the fishery harvesting in up downstream in netting gear separately; Netting gear structure is simple, arranges simple and easy, saves a large amount of manpower and materials, improves sampling efficiency; Fish bulk damage is avoided in this device institute fishing capacitation.
Description
Technical field
The utility model is used for fishing net's technical field, particularly relates to a kind of flowing water and gathers fish sample device.
Background technology
The research of rivers and streams resource investigation of fish is an important content of aquatic products and Hydrobiology subject, sampling in difference position, river to needing during resource investigation of fish.The sampling of current fish sample typically use draw in the net, gill net, longline fishing, the Sampling nets such as cage, because riverbed structure is complicated, except uneven bottom riverbed, also has the extraordinary fish habitat place such as cave and mud, draw in the net, gill net etc. is difficult to paste the fish that trip warp is fished at the end, and can only fish for the fish sample larger than mesh specification.The bait that longline fishing uses has stronger selectivity, and cage class mainly fishes for demersal fishes.So use draw in the net, that gill net, the sampling tool such as longline fishing and cage singly do not fish for selectivity is high, also to fish sample damage comparatively greatly, and class that None-identified is fished is from sampled point upstream or downstream.
Utility model content
For solving the problem, the utility model provides a kind of flowing water to gather fish sample device, can conveniently at the middle and upper levels, lower floor fish sample simultaneously, and can sample respectively to fish that are up, downstream, do not damage adopted fish sample, save manpower and material resources, improve sampling Efficiency, solve the Sampling in flowing water region.
The utility model solves the technical scheme that its technical problem adopts: a kind of flowing water gathers fish sample device, comprise and be positioned at upstream and draw net in the upstream that " eight " word is arranged and be positioned at downstream and draw net in the downstream that just " eight " word is arranged, described upstream is drawn net and downstream and is drawn the block that Netcom crosses both sides and be connected, and form fish gathering district in inside, described upstream is drawn net and downstream and is drawn between net and be provided with filter, fish gathering is distinguished and is divided into and descending fish district and descending fish district by described filter, lymphogranuloma inguinale is drawn in the upstream that the described descending fish district of net formation remittance is drawn in described upstream, lymphogranuloma inguinale is drawn in the downstream that the described descending fish district of net formation remittance is drawn in described downstream.
Be further used as the improvement of technical solutions of the utility model, net is drawn in described upstream, net is drawn in downstream, block and filter be all longitudinally arranged in water body by column.
Be further used as the improvement of technical solutions of the utility model, the block that net and Yin Wang both sides, downstream are drawn in described upstream is all equipped with fish gathering bag, the afterbody tying of described fish gathering bag is also connected on the column at rear by rope.
Be further used as the improvement of technical solutions of the utility model, the porch of described fish gathering bag is provided with inverted beard, the built-in annular float of fish gathering bag.
Be further used as the improvement of technical solutions of the utility model, net is drawn in described upstream, net is drawn in downstream, the exaggerated of filter, block bind a float every 10cm, infraclass binds a weight every 5cm.
The beneficial effects of the utility model: the utility model forms fish gathering district by the inner small and outside big net that draws in "eight" shape of twice, makes the fish in up downstream introduce in netting gear smoothly, is difficult to flight; In "eight" shape draw net draw lymphogranuloma inguinale can according to the fish individual size of sample area adjustment width; A slice filter is used to enter the fishery harvesting in up downstream in netting gear separately; Fish gathering district is connected to the fish gathering bag of inverted mustache mouth, makes fish concentrate on fish gathering bag and cannot return; The tying of fish gathering bag afterbody can be opened easily and take out adopted fishery harvesting; The built-in annular float of fish gathering bag makes fish gathering bag part road go out the water surface, avoids the fishery harvesting death by suffocation of failing in fish gathering bag to take out in time; Netting gear structure is simple, arranges simple and easy, saves a large amount of manpower and materials, improves sampling efficiency; Fish bulk damage is avoided in this device institute fishing capacitation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
With reference to Fig. 1, the utility model provides a kind of flowing water and gathers fish sample device, comprise and be positioned at upstream and draw net 1 in the upstream that " eight " word is arranged and be positioned at downstream and draw net 2 in the downstream that just " eight " word is arranged, described upstream is drawn net 1 and is drawn net 2 with downstream and be connected by the block 3 of both sides, and form fish gathering district in inside, described upstream is drawn net 1 and downstream and is drawn between net 2 and be provided with filter 4, fish gathering is distinguished and is divided into and descending fish district 51 and descending fish district 52 by described filter 4, is gathered in Liang Ge fish gathering district respectively to make the fish after entering fish gathering district; Lymphogranuloma inguinale 11 is drawn in the upstream that the described descending fish district 51 of net 1 formation remittance is drawn in described upstream, and lymphogranuloma inguinale 21 is drawn in the downstream that the described descending fish district 52 of net 2 formation remittance is drawn in described downstream.
Wherein, net 1 is drawn in described upstream, net 2 is drawn in downstream, block 3 and filter 4 are all longitudinally arranged in water body by column 6, and net 1 is drawn in described upstream, net 2 is drawn in downstream, filter 4, the exaggerated of block 3 bind a float every 10cm, infraclass binds a weight every 5cm.Described upstream draw net 1 and downstream draw net 2 both sides block 3 on fish gathering bag 7 is all housed, the afterbody tying of described fish gathering bag 7 is also connected on the column 6 at rear by rope.The porch of described fish gathering bag 7 is provided with inverted beard 71, the built-in annular float 72 of fish gathering bag 7.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
