Abstract
The utility model discloses the device of a kind of Japanese ghost Rockfish live seedlings of high efficiency screening and dead seedling, including plastic floating ball, stainless steel frame, bolting silk net, the stainless steel frame is by two stainless steel annulus and the stainless steel welded cylinder of three trifles；The stainless steel frame diameter 50cm, height 1.5cm；The plastic floating ball is connected to above stainless steel frame, in triangular arranged；The bolting silk net is 20 mesh, tightens and is bound to stainless steel frame bottom surface and side.The apparatus structure of a kind of Japanese ghost Rockfish live seedlings of high efficiency screening of the utility model and dead seedling is simple, easy to operate, can convenient, the efficient residual bait excrement that Japanese ghost Rockfish dead seedlings and bulky grain are screened out from live seedling.It is simple to operate, unnecessary work is reduced, has ensured that the health of seedling raising environment is suitable, has reduced the generation of disease.
Description
Technical field
The utility model is related to the device of a kind of Japanese ghost Rockfish live seedlings of high efficiency screening and dead seedling, belongs to batch production fish hatching
Field.
Background technology
Japan ghost Rockfish is that a kind of typical bottom is dwelt the love reef fish of life, and its fine and tender taste, delicious flavour are that one kind has
The high-grade economic fish of higher Development volue.In recent years, because of reasons such as overfishing and environmental pollutions, this kind of fish natural resources is anxious
Play decline, therefore, from the beginning of this century, studies in China scholar starts to carry out Japanese ghost Rockfish artificial breeding work successively.At present, state
Inside it has been successfully established Japanese terrible Rockfish artificial breeding techniques method.In Japanese ghost Rockfish seedling raising process, at the beginning of Japanese ghost Rockfish
Sub- fish membrane is incubated after 15 days, a development by metamorphosis is had and lies prone the process at bottom, in order to ensure being smoothed out for nursery, improve nursery
Efficiency, reduces work difficulty and saves workload, it is necessary to which the Japanese ghost Rockfish seedlings at bottom of lying prone are pulled out in pond, be put into Japanese ghost Rockfish
Further cultivated in special net cage.And the Japanese ghost Rockfish seedlings behind bottom of lying prone are not liked to move about, it is very slow to take action, and likes cluster
Lie prone in corner, stimulate to external world insensitive.Therefore in this period, sub-sieve goes out the dead of normal loss from Japanese ghost Rockfish live seedlings
Seedling and the bulky grain residue produced during feeding intake are very difficult.The serious work difficulty for improving nursery work and work
Amount, constrains the further development of Japanese ghost Rockfish industrial seedling rearings.
The content of the invention
The purpose of this utility model is the defect for overcoming prior art to exist, and provides a kind of high efficiency screening Japanese ghost Rockfish
The device of live seedling and dead seedling, the device is simple to operate, reduces unnecessary work, has ensured that the health of seedling raising environment is suitable, has subtracted
The generation of disease is lacked.
In order to realize the purpose of this utility model, adopt the following technical scheme that：
The device of a kind of Japanese ghost Rockfish live seedlings of high efficiency screening and dead seedling, including plastic floating ball, stainless steel frame, bolting silk net,
It is characterized in that：The described beautiful net of sieve tightens the bottom surface and side for being tied to stainless steel frame, and a plane is formed on whole bottom；Institute
The plastic floating ball stated is connected to the top of stainless steel frame with tether, in triangular arranged.
It is preferred that, described stainless steel frame, be the annulus and three trifle stainless steels of two stainless steels support welding and
Into cylindrical type rack-like structure；Described support is in triangular arranged.
It is preferred that, described circle diameter is 50cm, and support height is 1.5cm.
It is preferred that, described bolting silk net, mesh is 20 mesh.
It is preferred that, described plastic floating ball is located at the surface of support.
The utility model advantage is：Stainless steel frame diameter 50cm, height 1.5cm, can make live seedling be relatively easy to trip
Go out outside described stainless steel frame, dead seedling and large granular impurity can again stayed in described stainless steel frame；Plastic floating ball connects
Be connected to above stainless steel frame, in triangular arranged, when floating on the water surface, described device can be kept to balance, but it is described not
Steel frame immersion become rusty under water, apart from water surface 5cm or so；Bolting silk net is 20 mesh, in water movement side small to the inhibition of current
Just, dead seedling and bulky grain residue is avoided to spill again.Bolting silk net, which is tightened, is bound to stainless steel frame bottom surface and side, whole bottom shape
It into a plane, Japanese ghost Rockfish live seedlings and dead seedling etc. is laid in bottom, reduce covering and stack phenomenon.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model device；
Fig. 2 is the schematic diagram of the stainless steel frame of the utility model device；
Wherein 1- plastic floating balls, 2- stainless steel frames, 21- annulus, 22- supports, 3- bolting silk nets.
Embodiment
The utility model is described in further detail with reference to embodiments.
The utility model provides the device of a kind of Japanese ghost Rockfish live seedlings of high efficiency screening and dead seedling, as shown in Figure 1：Including plastics
Ball float 1, stainless steel frame 2, bolting silk net 3：Sieve beautiful net and tighten the bottom surface and side for being tied to stainless steel frame, whole bottom forms one
Individual plane；Plastic floating ball is connected to the top of stainless steel frame with tether, in triangular arranged；
Wherein：The circle that stainless steel frame is welded for the support 22 of the trifle stainless steel of annulus 21 and three of two stainless steels
The rack-like structure of column type, support is in triangular arranged (as shown in Figure 2)；
Circle diameter is 50cm, and support height is 1.5cm；Bolting silk net, mesh is 20 mesh；
Plastic floating ball is located at the surface of support.
When the dead seedling of normal loss in Japanese ghost Rockfish seedling net cages reaches that a certain amount of or long-time is not cleared up, it can use
During the utility model：Before screening, first the utility model device is placed in Japanese ghost Rockfish seedling net cages, Japan out will be collected
Terrible Rockfish live seedlings and the mixture of dead seedling and large granular impurity are slowly poured on the middle position of the utility model bolting silk net 3, and level is small
Amplitude shakes the utility model, the mixture of Japanese ghost Rockfish live seedlings and dead seedling and large granular impurity is tried one's best and is laid in bolting silk net
3 bottoms, outwards move about upwards while having part live seedling and being upset；Level is shaken by a small margin continuously and healthily, is stayed enough
Live seedling it is stimulated it is travelling upwards after, slow level is pulled more than the utility model 60cm distances, is departed from after live seedling upstream region, weight
Acted more than multiple.Lift the utility model 3cm or so then up, then slowly put down, stimulated move about of live seedling is suspended in water
In, and dead seedling follows the utility model to fall downwards, slow level is pulled more than the utility model 60cm distances, departs from live seedling trip
Behind dynamic region, repeat to act above again.After so repeatedly 4-5 times, most live seedlings can be entered Japanese ghost Rockfish nursery by sub-sieve
In net cage, few part can be transferred in band water bucket by selecting by hand, or together with dead seedling, treat live seedling because of hungry and ring
Live seedling is pulled out when uncomfortable travelling upwards in border.
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.
