Description
Technical field
The utility model is related to aquatic product fishery field more particularly to a kind of selective shrimping cages.
Background technology
At present, paddy field aquaculture, pond culture and wild cray all there is a situation where not of uniform size, at present, in the market
The shortcomings that fishing net of small dragon mornig shift fishing purchased is there are in terms of four, when during the fishing of cray, it is not of uniform size
Cray all fishing network, return cultivation again after screening, seedling caused to be damaged seriously；Second is that the cray of fishing is big
It is small in unbalanced problem, fishing after will pass through artificial screening classification post-processing sale, cause human cost excessive；Third,
During fishing, cray is covered with entire fishing net, in fishing after the problem of passing through artificial capture method, causing human cost excessive；
Fourth, fishing benefit, existing fishing net fishing benefit is relatively low；As cray industry is national fast-developing, how by cray
Fishing listing is that there are one weight links for cray industry development.Since cage net netting is too small, it is unfavorable for the protection of fishery resources,
According to " the Fishery Law of the People's Republic of China " chapter 4 Article 30 and the regulation of the 38th article of chapter 5, cage is mostly
Fisheries management regulations in have been cited as disabling fishing gear.But the development of cray aquaculture industry, cage fishing tool are industries
One important link of development, belongs to essential node in cultivating link, is legally not belonging to the scope forbidden, needs
How a kind of fishing tool mainly for fishing pool cultivation, the symbiosis of rice shrimp and wild cray is caught using cage raising
The effect of the cray of fishing is important topic there are one modern cray industry developments, and modern cray industry needs one kind can
Solve the cage suitable for shrimping of difference between fishing and shrimping.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of suitable for shrimping, catching rate height, energy
Selectivity set catch, pinpoint collect cray, save manually selective shrimping cage.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of selectivity shrimping cage, it is characterised in that：It includes cage body, cage tail, and cage body both ends are connected with cage tail, make
Cray in cage body can smoothly reach cage tail, and the cage body is sewed by rectangular frame 1 and screen cloth 2, with two rectangle frames
Frame 1 is a section with the space that screen cloth 2 surrounds, and forms the space of closing with the cray shrimp for entrance of bottling up, the cage body is provided with
21-43 is saved, and 2 side of screen cloth that cage body often saves is provided with bellmouth entrance 3, and the bellmouth entrance 3 is in funnel-form into cage body
Portion is shunk, and cray is made to be difficult to find an exit again and escape from after entering, and cage body, which often saves, is additionally provided with splayed door 5, the splayed door 5 to
Cage tail direction becomes narrow gradually, and makes cray that can only constantly swim to cage tail, cage body and cage tail and is connected by two rectangular frames 1, to
Fixed cage body is indeformable, and the cage tail is sewed by circular frame 4 and screen cloth 2, forms the space of closing to prevent cray
It escapes from, the funnel-form palpus mouth 6 rearwardly extended is provided on the circular frame 4, makes cray that can only constantly swim to cage tail most
The shrimp bag 7 of tail end prevents cray from returning to cage body and drills out cage, reduces amount of fishing, and the cage tail tail end is provided with shrimp bag 7, uses
Collect the cray of capture, the bellmouth entrance 3, splayed door 5, funnel-form must be fitted with down on the inside of mouth 6 and cage body
Must, it further limits cray and migrates.
As being further improved for above technical scheme：
The rectangular frame 1 and circular frame 4 are bent after penetrating plastic pipe using wire, both ensure that frame
Intensity makes it have certain antirust, anti-corrosive performance again, prolongs the service life.
The splayed door 5 includes two veils, and one end of net is connected with cage body, and the other end is mutually collapsed to centre, from top
See the shape in eight words, the net that lobster is collapsed to centre limits, and can only swim the position to crack between a door and its frame, is difficult again after in the past from crack between a door and its frame
It flees back to come from crack between a door and its frame, can only continue caudad to swim.
The mesh-density of the screen cloth 2 is 2-4.5cm, using the density size of 2 grid of screen cloth, catches the small dragon of equal-specification
Shrimp, realization, which is caught, to be stayed greatly small, is reduced the cost of artificial people screening, is improved labour efficiency.
Compared with prior art, the utility model has the advantage of：
Suitable for shrimping, catching rate is high, can selectively cover and catch, pinpoint and collect cray, save manually.With the prior art
Compare, this technology is to complete screening step by mesh-density, reduces the damage to seedling, reduces loss, reduce manpower into
This, so as to improve efficiency；The link for collecting cray and saving artificial capture method is pinpointed by the shrimp bag of tail end, further reduces people
Work cost improves working efficiency, and whole catching rate is made to be greatly improved than the fishing net fishing used at present.
