Description
Technical field
The utility model patent is related to a kind of grading plant of fish seedling, and in particular to a kind of point of flounder flounder fish fry
Stage arrangement, belongs to marine fish culture assessment technique field.
Background technology
Flounder flounder class, including the fish such as Bothidae, Pangasiidae, Soleidae, belong to higher one of economic value in the demersal fishes of ocean
Major class, is always aquaculture pair important both at home and abroad the features such as good mouthfeel and higher nutritive value because of its ecologicaI distribution extensively
As deep to be liked by domestic and international consumer and researcher.In China, turbot, Cynoglossus semilaevis and lefteye flounder are that flounder flounder class is main
Breed variety.Healthy seedling is bred, elite germplasm is formulated, realizes breeding industrialization and coverage rate, is following Technique in Fishes cultivation
Mainstream development direction.During left-eyed flounder seed breeding, prelarva will undergo a typical eye migration, life first
Mode is changed into bottom from swimming and dwelt type development by metamorphosis process, and the course of reaction is related to violent reconstruction of tissue and organ, is turbot seedling
Plant the death rate highest stage in cultivating process.After allergy terminates simultaneously, due to ontogeny difference and exogenous nutrition
Intake is unbalanced, and the resistance of prelarva and growth can show notable difference.Therefore, it is indefinite in seed rearing production process
Phase carries out seed diversity and selected, to ensure nursery success rate, improves culture benefit, and traditional classification, which is selected, generally utilizes dredger root
According to fish body size, the tail of a tail one is selected step by step, time-consuming, laborious, while election process produces exogenous stress to fry, causes seedling
Plant resistance to decline, directly affect fry quality, thus need a kind of efficiently and effectively flounder flounder class seed of offer to be classified device for sorting
And method.
The content of the invention
Technical problem to be solved in the utility model is to be directed to the deficiencies in the prior art, and provides a kind of flounder flounder
The grading plant of fish fry, quiet, Xi Zang, easily frightened etc. characteristic are typically all liked using fish fry, and design can be multistage automatic point
The device of sieve, the device have reasonable in design, simple in construction, automatic multi-step sub-sieve, artificial operation less, fry damage small, easy behaviour
Many advantages, such as work, convenient disassembly, the deficiencies in the prior art can be made up and improved using the method, solve existing flounder sole
Sizing screening is time-consuming during class Seedling production, effort short slab.
To achieve these goals, the utility model is adopted the following technical scheme that：
A kind of grading plant of flounder flounder fish fry, main body is to have three faces in rectangular casing, the four sides of casing
The one side open provided with tank wall, the open top of casing and is equipped with case lid；It is characterized in that：
Described box house is hollow, and the inside of two relative tank walls is equipped with extracting slide rail, while being equipped with to take out
Sieve nest draw, extraction type, the one side that sieve nest is opened by casing is pulled out；
The number of described sieve nest is 5, and the bottom of each sieve nest offers sieve aperture.
It is preferred that, the outside of described sieve nest is equipped with handle.
It is preferred that, the sieve nest described in 5, the pore size of its sieve aperture is different.
It is preferred that, the sieve nest described in 5, from top to bottom the aperture of its sieve aperture be followed successively by 10cm, 8cm, 7cm, 6cm, 5cm.
The application method of the utility model device is：The case lid of casing is opened, flounder flounder fish fry is put into topmost
In sieve nest, the aperture of the sieve aperture of the sieve nest of topmost is maximum, a part of fish seedling from sieve aperture leaks to next layer of sieve nest, and
The specification of the flounder flounder fish fry stayed in the superiors' sieve nest is then more than 10cm, and the sieve nest, which is pulled out, can obtain dimension
Seed；And the seed drained in lower floor's sieve nest, according to same principle, specification is obtained more than 8cm, the seed less than 10cm, and
The seed that specification is less than 8cm is drained into lower floor's sieve nest；According to such screening technique, you can obtain the seed of different stage.
The design principle of the utility model device is：First according to turbot, Cynoglossus semilaevis and lefteye flounder early development characteristic
Actual, three kinds of main breed varieties of flounder flounder class with reference to breeding production, seed step-sizing process is all after allergy, and individual is raw
Long difference is appeared between 6~10cm, while its body is high also different.During body 6~10cm of length, turbot body a height of 4~
7cm, a height of 3~5cm of Cynoglossus semilaevis body, the high 3~5cm of lefteye flounder body, therefore according to body length and a kind of quick seedling of the high different designs of body
Plant step-sizing device.
The advantage of the utility model device is：Structure design is simple, can according to production needs, selection different pore size can
Pull, extraction type sieve nest, carries out different size seed and selects, applicability is wide；Integrated operation process control performance is high, seed
It is difficult because anoxic, mechanical damage cause death.

Embodiment
The embodiments of technical solutions of the utility model is described in detail below, but the utility model be not limited to
Lower description content：
A kind of grading plant of flounder flounder fish fry, as Figure 1-3：Main body is a rectangular casing 1, casing
There are three faces in four sides provided with tank wall and one side open, the open top of casing and be equipped with case lid 5：
Described box house is hollow, and the inside of two relative tank walls is equipped with extracting slide rail, while being equipped with to take out
Sieve nest 2 draw, extraction type, the one side that sieve nest is opened by casing is pulled out；
The number of described sieve nest is 5, and the bottom of each sieve nest offers sieve aperture 4, and the pore size of sieve aperture is different,
The aperture of its sieve aperture is followed successively by 10cm, 8cm, 7cm, 6cm, 5cm from top to bottom；
The outside of described sieve nest is equipped with handle 3.
Using this device, in Yantai, Tian Yuan aquatic products is respectively from 2000 urosome length in 6~10cm turbot, half sliding-tongue he and tooth
Flounder, with manually being contrasted by tail seedling separation, while under two kinds of difference stage divisions of tracing detection, short time consumption, the seed death rate,
Lysozyme, superoxide dismutase activity, as a result show, using the seed death rate after this device short time consumption and seedling separation 4 hours
It is substantially lower than artificial to be significantly higher than by tail seedling separation, lysozyme and superoxides enzymatic activity manually by tail seedling separation, as a result such as following table
It is shown：
| The death rate | Antalzyme activity | Superoxide dismutase | It is time-consuming | |
| Manually select step by step | 8.58±0.84 | 24.87±4.52 | 36.16±3.52 | 10 minutes |
| Grading plant is selected | 3.09±0.33 | 41.35±3.52 | 47.24±2.52 | 25 minutes |
Therefore, the utility model apparatus and method are classified during can effectively lifting flounder flounder class seed rearing and selected, and improve and raise
Feed and way to manage, the high-quality seed rearing for flounder flounder class provides technical support.
Examples detailed above simply to illustrate technical concept of the present utility model and technical characterstic, can not limit this reality with this
With new protection domain.All equivalent transformations done according to essence of the present utility model or modification, should all cover in this reality
Within new protection domain.
