Abstract
The utility model provides a device of high-density factory farming of loach. The device comprises a float, a fastening chassis and a sinker, wherein the sinker is fixed below the fastening chassis, and the two sides of the fastening chassis are respectively and fixedly provided with fastening rods; perching pieces are uniformly distributed on the fastening rods up and down at an interval of 30cm. The device of the high-density factory farming of the loach includes design, construction and management of the perching device for farming the loach, and the three-dimensional surface area of a water body for farming the loach is increased, so that more loach can perch on the perching device more comfortably; the manual loach perching device is placed in the farming water body to meet the benthic biological characteristic of the loach, and the device has the advantages that the surface area is large, the device is expanded at the upper middle part of the water body in a layered way, and feces, residual baits and other substances are not easily accumulated on the surface of the device.
Description
Technical field
The utility model belongs to aquaculture field, specifically the device of a kind of high density industrial aquaculture loach.
Background technology
Loach (Misgurnus anguillicaudatus) is subordinate to Cypriniformes (Cypriniformes), Cobitidae (Cobitidae).Loach fine and tender taste, delicious flavour, nutritious and be rich in mineral matter and multivitamin, also have the laudatory title of " ginseng in water ", welcome by domestic and international market.
Loach gill respiration, skin and intestines have the function of assisted respiartion, when at the bottom of the same day unhappy heat or pond, the material such as mud, humus rots to cause severe depletion of oxygen, loach also can be primered, or vertical lifting is to the water surface, directly swallows air with mouth, carries out assisted respiartion by intestines wall.So most raisers thinks that loach can anoxic, cultivation density is often very high, has caused like this that loach adaptability reduces, disease increases, survival rate declines, and feed coefficient increases.
Chinese patent CN102440213A discloses the indoor stereo cultivator of a kind of crab, this device has one to be listed as into the drawer position being arranged above and below, the crab nest of a drawer form is installed in each drawer position, said crab nest has water inlet and gap, connect respectively feed water inlet and the water return outlet of circulating water by pipeline, said circulating water refers to the EGR being made up of storage tank and water pump and links up the pipeline between crab nest and between crab nest and EGR.This patent is arranged on crab nest and in shelf, forms the upper and lower interdependent row of several crab nests and be connected in circulating water as drawer.This patent can realize indoor carries out highdensity three dimensional-breeding, and conveniently every foster crab is managed separately, and breeding environment is also because the semiclosed of crab nest seems clean.But this apparatus structure complexity, only suitable shrimp crab cultivation.
Therefore, for loach high-density breeding problem, the equipment of perching of a whole set of practicable loach high-density breeding is proposed, significant to improving loach high-density breeding (comprising pond and cycle water high density loach breeding) economic benefit.
Utility model content
Perch space in order to improve loach, reduce loach and produce the problem of extruding mutually because have a rest on the same face, solve loach in high-density breeding process because the mutual extruding of generation of having a rest easily produces disease propagation and the problem with emergency reaction on the same face, the utility model provides the device of a kind of high density industrial aquaculture loach, comprise float, fastening chassis and sinker, described sinker is fixed on below, fastening chassis, the both sides on described fastening chassis are fixed with respectively anchorage bar, perching sheet is uniformly distributed on anchorage bar up and down, the adjacent 30cm that is spaced apart of perching between sheet.
The quantity of perching sheet further, is 15.
Further, every area of perching sheet is 0.45m
2.
Further, described in, perching sheet is made up of transparent plastic sheet.
Further, this device is placed on culturing pool middle body.
The device of high density industrial aquaculture loach of the present utility model, comprises that breeding loach perches the design of device and construction, management, increases the water body neutral body surface area of breeding loach, and more many loach can more comfortablely be perched in the above; Meet the biological property of dwelling property at the bottom of loach, place artificial loach for this reason and perch device in breeding water body, it is large that this device has surface area, expands by different level in water body middle and upper part and divide, and apparatus surface is difficult for the advantage of the materials such as the residual bait of deposition ight soil.
The utility model breeding loach density is large, volume increase is many, risk is low, high efficiency, practicality are wide, in an open water body, need only just relatively fix can, easy for installation, good economy performance, suitable high density industrial aquaculture loach.
Brief description of the drawings
Fig. 1 is the apparatus structure schematic diagram of high density industrial aquaculture loach of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The device of high density industrial aquaculture loach of the present utility model, comprise float 1, fastening chassis 2 and sinker 3, sinker 3 is fixed on 2 belows, fastening chassis, the both sides on fastening chassis 2 are fixed with respectively anchorage bar 4, perch sheet 5 and be uniformly distributed in up and down on anchorage bar 4, the adjacent 30cm that is spaced apart of perching between sheet 5.This device has 15 and perches sheet 5, and every area of perching sheet 5 is 0.45m
2.Perching sheet 5 is made up of transparent plastic sheet.
This device is generally placed on culturing pool middle body, and the quantity of placement of multiple layers device in the water body of high density industrial aquaculture loach, should arrange according to cultured output; Multi-layered devices area is exactly to perch face portion upward, and multi-layered devices is close with common shutter, and the fecal materials rapid precipitation of favourable like this precipitation accumulation runs up to culturing pool bottom, and convenient collection discharged.Placement of multiple layers device economy in water body, makes and movement easy to use.
In the East Sea, Xiaoshan, Hangzhou, Zhejiang province, cultivation Co., Ltd has carried out the test of loach cycle water intensive culture technology:
Be for experiment 8 of culturing pools, area is respectively 400 ㎡, and wherein 4 culturing pools have been placed the multi-layered devices of breeding loach, and other 4 is blank, lasts 61, and correlated results is as follows:
1, growth rate: 4 times, front and back sampling Detection loach growing state, obtains the growth parameter(s)s such as the individual weight of different breeding period loach, gain in weight and Average weight increasing a day; Through relatively, there is notable difference in the loach growth that 2 kinds of differences are put in a suitable place to breed under mode, and result shows, the individual average specification of loach increases to 15.31g and 16.32g by every tail 3.6g respectively, respectively increases by 3.253 times and 3.532 times, average daily each increasing 0.192g and 0.209g.
2, survival rate: calculate total mantissa according to individual weight, cultivation survival rate is respectively 92.4% and 93.2%.
3, feed coefficient: feed coefficient is respectively 1.56 and 1.54.
Evidence: the multi-layered devices of placing breeding loach has caused the enhancing of loach adaptability, disease to reduce, survival rate improves, feed coefficient declines.
