Description
Technical field
The utility model is related to a kind of dredger for Japanese ghost Rockfish nursery, 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 Development volue higher.In recent years, because of reasons such as overfishing and environmental pollutions, this kind of fish natural resources urgency
Play decline, therefore, from the beginning of this century, studies in China scholar starts to carry out the artificial breeding work of Japanese ghost Rockfish successively.At present, state
Inside it has been successfully established Japanese terrible Rockfish artificial breeding techniques method.In the seedling raising process of Japanese ghost Rockfish, there is an abnormal hair
Educate the process at bottom of lying prone, in order to ensure nursery be smoothed out, it is necessary to the Japanese ghost Rockfish seedlings at bottom of lying prone are pulled out from pond, be put into day
Further cultivated in this terrible Rockfish special net cage.And found during being fished for ground fish seedling of lying prone, because Japan ghost Rockfish lies prone
Do not like to move about behind bottom, bradykinesia likes cluster to lie prone in corner, stimulates insensitive to external world, causes the dredger of traditional fry
Use Limitation rate is very beneath, operating difficulties, and easy sticky net, by mistake pressure, by mistake wiping etc. cause the damage of Japan ghost Rockfish fries.
The content of the invention
The utility model overcomes the shortcomings of that above-mentioned prior art is present, and provides a kind of dragging for for Japanese ghost Rockfish nursery
Net, efficiently can easily catch the Japanese ghost Rockfish fries of bottom phase of lying prone, and can the Japanese ghost Rockfish survival rate of fish frys of effective guarantee dredger,
Unnecessary work is reduced, and guarantee does not have fish that has escape the net.
To achieve these goals, the utility model patent is adopted the following technical scheme that：
A kind of dredger for Japanese ghost Rockfish nursery, including plastic handle, plastic frame, the bolting silk string bag and plastics scoop,
It is characterized in that：
Described plastic frame is rectangle, and the centre on one side long is installed with described plastic handle, with
Another relative side long described plastics scoop is installed；Four sides of plastic frame connect with the surrounding of the described bolting silk string bag
Connect；
Described plastics scoop is in 150 degree of angles with the side long of plastic frame.
Preferably, described plastic handle, length is 30cm.
Preferably, described plastic frame, a length of 60cm, a width of 40cm.
Preferably, described plastic frame, is the framework of gray tinted plastic composition.
Preferably, the described bolting silk string bag, is that an equal amount of isosceles trapezoid bolting silk mesh sheet of two panels and two panels are onesize
Equilateral triangle bolting silk net piece suture form, reveal all the details shallower.
Preferably, the described bolting silk string bag, sieve number is 60 mesh.
Preferably, described plastics scoop, is the scoop of silvery white plastics composition.
The utility model advantage is compared with traditional dredger：Plastic frame lower end is connected with plastics scoop, plastics scoop
Be silvery white, in plastics scoop when being pushed away before bottom of pond, can effective stimulus lie prone ground Japan ghost Rockfish move about forward and up so that
Collected as in the bolting silk string bag by plastic frame.Plastic frame is rectangle, and a length of 60cm, a width of 40cm, area is larger, can effectively be received
The Japanese ghost Rockfish seedlings that collection moves about from the whole water layer from bottom of pond to the water surface.Plastic frame grey, can be reduced to Japanese ghost Rockfish seedlings
Stimulate.Plastics scoop and plastic frame into 150 degree of angles, promote more laborsaving and plastic frame collection area bigger, close to
Its real area.The bolting silk string bag is 60 mesh, by an equal amount of by an equal amount of isosceles trapezoid bolting silk mesh sheet of two panels and two panels
The suture of equilateral triangle bolting silk net piece is formed, and is revealed all the details shallower, and the sticky net and mutual extruding for effectively preventing Japanese ghost Rockfish seedlings are rubbed
Damaged caused by wiping.
The utility model device, simple structure is easy to operate, can convenient, efficient seizure Japan ghost Rockfish lie prone the fry at bottom,
And can effective guarantee Japan ghost Rockfish lie prone the survival rate of ground fish seedling.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the dredger that the utility model is used for Japanese ghost Rockfish nursery；
Fig. 2 is plastic frame, the plastics scoop connection diagram that the utility model is used for Japanese ghost Rockfish nursery；
Wherein：1 is plastic handle, and 2 is plastic frame, and 3 is the bolting silk string bag, and 4 is plastics scoop.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of dredger of Japan's ghost Rockfish nursery, is made up of plastic handle 1, plastic frame 2, the bolting silk string bag 3, plastics scoop 4.
Plastic handle 1 is connected on the side center position long of plastic frame 2.The side long another with plastic frame 2 of plastics scoop 4 is connected, and is mutually
150 degree of angles.The length of plastic handle 1 is 30 centimetres.Plastic frame 2 is rectangle, a length of 60cm, a width of 40cm.The bolting silk string bag 3
It is 60 mesh, is formed by an equal amount of trapezoidal bolting silk net piece of two panels and an equal amount of triangle bolting silk net piece suture of two panels, sieves
Tulle pocket 3 and the side adhesion of plastic frame 2 four.
When the present apparatus is used, first the cement pool water level by Japanese ghost Rockfish nursery drains into 30cm, and hand-held plastic handle slowly hangs down
Directly make plastics scoop contact chamber bottom downwards, to avoid plastics scoop from being pressed onto fry, being pushed behind plastics scoop contact chamber bottom makes plastics
Scoop and bottom of pond make along adjoined water surface on plastic frame into 30 degree of angles or so, and uniform speed slow promotes forward the device, makes the ground fish that lies prone
Upstream moved after seedling is frightened and arrested in the bolting silk string bag, the fry that part is moved about in water layer originally is also arrested simultaneously.
Fry is moved into the bucket with water after the fry collection in the bolting silk string bag is enough, continues to repeat action above with the device, directly
Extremely fry is arrested totally.
The utility model is used for the dredger simple structure of Japanese ghost Rockfish nursery, easy to operate, can convenient, efficient seizure day
This terrible Rockfish lies prone the fry at bottom, and can effective guarantee Japan ghost Rockfish lie prone the survival rate of ground fish seedling.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created not
It is limited to the embodiment, those of ordinary skill in the art can also make on the premise of without prejudice to the utility model creative spirit
A variety of equivalent modifications or replacement, these equivalent modifications or replacement are all contained in the application claim limited range
It is interior.
