Abstract

The utility model discloses a kind of Macrobrachium rosenbergii and perch net, relate to the technical field of aquatic product fishery, including perching dictyosome, flush ring and foam floating block, the side perching dictyosome is closed, and these two ends perching dictyosome form two relative openings;Draw ring is connected to perch on the both sides that dictyosome is relative in mobilizable mode;Foam floating block is arranged at perches in dictyosome, and centre that the barycenter of this foam floating block is positioned at two draw rings being oppositely arranged, two draw rings being oppositely arranged are symmetrical for axis of symmetry with the barycenter place plumb line of foam floating block.This utility model, by rationally increasing the area of perching of Macrobrachium rosenbergii, improves the cultivation density in unit fish pond, thus improves yield.

Description

A kind of Macrobrachium rosenbergii perches net
Technical field
This utility model relates to the technical field of aquatic product fishery, is specifically related to a kind of Macrobrachium rosenbergii and perches net.
Background technology
Macrobrachium rosenbergii has another name called Malaysia prawn, the long-armed prawn of fresh water, is a kind of large-scale fresh water shrimp, originates in east South Asia.It has, and growth is fast, feeding habits wide, meat nutrition is good, and the advantage such as the culture-cycle is short.From this Since the sixties in century starts artificial cultivation Macrobrachium rosenbergii, quickly grow, achieve obvious economic benefit, It is one of three big shrimp species that cultivation amount in the world is the highest.
Dwelling life in the Macrobrachium rosenbergii battalion end, hides general daytime in the bottom or pasture and water clump, and out look for food in the evening.Cause When building cultivation fish pond, this needs that Macrobrachium rosenbergii is perched space and is designed, its size perching space is straight Connect the yield affecting Macrobrachium rosenbergii.In prior art, the space of perching of Macrobrachium rosenbergii is only limitted to bottom fish pond, to fish Certain waste is caused in space, the pool, is unfavorable for improving yield.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of Macrobrachium rosenbergii and perches net, logical Cross the area of perching rationally increasing Macrobrachium rosenbergii, improve the cultivation density in unit fish pond, thus improve yield.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of Macrobrachium rosenbergii perches net, including:
Cultivation fish pond, the bottom in this cultivation fish pond is arc-shaped;
Be arranged in cultivation fish pond perches dictyosome, and this side perching dictyosome is closed, and this perches the two ends of dictyosome Form two relative openings;
It is connected to perch the draw ring on the both sides that dictyosome is relative in mobilizable mode;
Being arranged at the foam floating block perched in dictyosome, the barycenter of this foam floating block is positioned at two draw rings that are oppositely arranged Two draw rings middle, that be oppositely arranged are symmetrical for axis of symmetry with the barycenter place plumb line of foam floating block.
As a kind of improvement of the present utility model, perch dictyosome cylindrically.
Preferably, the mesh number scope perching dictyosome is 15 mesh~25 mesh.
It is further preferred that the mesh number perching dictyosome is 18 mesh.
Preferably, the length direction of draw ring is perpendicular to perch the length direction of dictyosome, and the length range of draw ring is 0.3m~1m.
It is further preferred that a length of 0.5m of draw ring.
The beneficial effects of the utility model are: contribute to bottom the fish pond of arc-shaped increasing cultured area;By side Banding closes, the dictyosome of perching of both ends open is placed in fish pond, and buoyancy suffered by foam floating block will make to perch net Body floats, bottom fish pond originally outside, add Macrobrachium rosenbergii perches area, space, effectively increases The cultivation density of Macrobrachium rosenbergii, it is effectively improved yield;Cylindric dictyosome of perching more preferably operates, it is to avoid because of The potential safety hazard that the too much wire gauze of corner angle causes;It is arranged at and perches the draw ring member convenient to operate of dictyosome both sides on the coast Operate perching dictyosome, dictyosome will be perched and move to become on the bank more to facilitate;It is arranged at and perches dictyosome both sides Draw ring adjacent perching also can be made to maintain a certain distance between dictyosome, the size of draw ring can be arranged as required to Reach the distance needed, it is to avoid perch dictyosome be closely adjacent to each other cause that nutrient distribution is uneven, quality is unequal asks in cultivation Topic;Mesh number and the length of draw ring perching dictyosome rationally it is provided with according to cultivating condition.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Reference: 1, perch dictyosome;2, foam floating block;3, draw ring.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As it is shown in figure 1, a kind of Macrobrachium rosenbergii perches net, including cultivation fish pond (not shown), perch dictyosome 1, Flush ring 3 and foam floating block 2, the bottom in this cultivation fish pond (not shown) is arc-shaped;It is arranged at cultivation Perching dictyosome 1 cylindrically in fish pond, this side perching dictyosome 1 is closed, and this perches the two ends of dictyosome 1 Forming two relative openings, the mesh number perching dictyosome 1 is 18 mesh;Draw ring 3 is in mobilizable mode respectively Being connected to perch on the both sides that dictyosome 1 is relative, the length direction of draw ring 3 is perpendicular to perch the length side of dictyosome 1 To, a length of 0.5m of draw ring 3;Foam floating block 2 is arranged at perches in dictyosome 1, the matter of this foam floating block 2 Centre that the heart is positioned at two draw rings 3 being oppositely arranged, two draw rings 3 being oppositely arranged are with the barycenter institute of foam floating block 2 It is that axis of symmetry is symmetrical at plumb line.
When this utility model uses, draw ring 3 is oppositely disposed in perching dictyosome 1 both sides, by foam floating block 2 Be placed into and perch in dictyosome 1 so that the barycenter of this foam floating block 2 be positioned at two draw rings 3 being oppositely arranged centre, Two draw rings 3 being oppositely arranged are symmetrical for axis of symmetry with the barycenter place plumb line of foam floating block 2;Also can root Placing pasture and water etc. according to needs on dictyosome 1 toward perching, will perch net subsequently is placed in fish pond, foam floating block 2 Buoyancy makes to perch dictyosome 1 and floats, then the Macrobrachium rosenbergii cultivated can be perched on dictyosome 1 perching, and draw ring 3 makes phase Adjacent perching maintains a certain distance between net, is conducive to improving cultivation efficiency.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other Various corresponding changes and deformation, and all these changes and deformation all should belong to this utility model power Within the protection domain that profit requires.
