Abstract
The invention discloses a fish fry sorting box. The fish fry sorting box comprises a box body and a floater. The box body comprises a bottom plate, a side plate, a lower fixing plate, and an upper fixing plate, so the cuboid opening structure is formed. The upper clearance is reserved above the lower fixing plate, and the lower clearance is reserved below the upper fixing plate. Two ends of the side plate are provided with a vertical groove. The groove is provided with a screw hole. A lag bolt is screwed in the screw hole. An upper active plate is inserted in the groove at one end of the lower fixing plate, and a lower active plate is installed in the groove at one end of the upper fixing plate, so the height of the upper clearance and the lower clearance can be adjusted and kept, and the individual with the same standard can be sorted by using the rheotaxis of the fish fry. The upper part of the side plate is provided with a screw hole. The floater is provided with two vertical slots, and the floater is fixed to the outer side of the side plate by using a stay bolt. The position of the floater is upwards and downwards moved so as to adjust the underwater penetration depth of the box body. The fish fry sorting box has the characteristics of simple structure and adjustable sorting standard, is capable of avoiding the problem that the fish bodies can be easily hurt and killed in the sorting process of the fish fry, and is suitable for sorting top-grade fish fry with delicate physique.
Description
Technical field
The present invention relates to a kind of point of fish box, and in particular to the method for separating of a kind of fry separatory vessel and fry, category is supported by fish
Plantation technology field.
Background technology
In fry cultivation, between Different Individual, the speed of growth is widely different, needs a large amount of by the fish of different size in time
Seedling point pond is raised, and fish sieve is usually used or fishnet is sorted in production.Body width is little less than sieve grid spacing or fish body cross section
In the individuality of mesh, can stay through fish and sieve or fishnet, larger individuality is then stayed in fish sieve or fishnet, different using multiple specifications
Fish sieve or fishnet filter out the fry of all size.As fish body is relatively soft, there are fin or hard thorn on fish body cross section, passing through
During screen cloth, a part of fish body unavoidably occurs and squeezes wound, tangles and dead, causes greater loss.
The content of the invention
The technical problem to be solved in the present invention is screening implement, the fish for solving to need plurality of specifications during current fry is screened
Body easily squeezes the larger problem of wound, death loss, improves the economic benefit of aquatic product sprout aquaculture.
The present invention solves above-mentioned technical problem, and the technical scheme of employing is：A kind of fry separatory vessel, comprising casing；It is described
Casing include base plate, side plate, bottom plate, upper mounted plate, constitute cuboid uncovered structure；The top of described bottom plate
Gap is left, lower gap below upper mounted plate, is left.
Preferably, described upper gap, lower chinky altitude can be adjusted as needed.
Further, described side plate two ends are provided with vertical groove；It is living in insertion in the groove of bottom plate one end
Dynamic plate, moves up and down upper mobile board, can adjust the height in upper gap；Portable plate under inserting in the groove of upper mounted plate one end, on
Portable plate under lower movement, can adjust the height in lower gap.
Further, described groove is provided with screw, screws in lag bolt and compress upper mobile board and lower activity in screw
Plate, gap and lower chinky altitude in fixation.
The casing is provided with floating block, casing is swum on the water surface.
Preferably, described casing underwater penetration can be adjusted up and down.
Further, the vertical slotted eye of twice is provided with floating block, screw above side plate, is provided with, with stay bolt by floating block
It is fixed on the outside of side plate, moves up and down the position of floating block, the underwater penetration of casing can be adjusted.
Using aforesaid fry separatory vessel separate different size fry, including determine sorting specification, adjust chinky altitude,
Adjust casing underwater penetration, flowing water and sort four steps.It is specific as follows：
1）It is determined that sorting specification：Several abortive haul casees are set in fishpond, fry to be sorted is focused in a net cage；Take out
Sample measurement fry most corpusculum length, largest body length and corresponding body are high, it is determined that sorting specification.
2）Adjust chinky altitude：Lag bolt is unclamped, the minimum fish body for sorting as needed highly arranges gap and lower seam
Gap height, tightens lag bolt.
3）Adjust casing underwater penetration：Stay bolt is unclamped, floating block position is adjusted, makes described fry separatory vessel keep afloat
When upper, the bottom of upper mobile board is identical with water surface elevation.
4）Flowing water is sorted：Described fry separatory vessel is put in fishpond in an abortive haul case, it is suitable to put into into casing
The fry to be sorted of quantity, makes flowing water state is kept in casing.Fry in casing is swum under the stimulation of anoxic and current against the current
Dynamic, body height is less than upper gap and the fry of lower chinky altitude swims out of casing against the current, and the high equal or slightly larger than upper gap of body is with
The fry of chinky altitude can lean to one side to swim out of casing after being subject to slight squeeze automatically.In casing, the fry of dimension is all swum out of
Afterwards, remaining larger specification fry in casing is thrown in another abortive haul case, continues the operation of repeat step 4 until minimum gauge
Fry is all sorted and focuses in same net cage；Repeat step 2 to 4 operate, reset gap, lower chinky altitude,
The position of floating block, sub-elects the fry of a big specification, until all specification fries all sort completing.
Preferably, when sorting upper strata fry, flowing water is poured at described upper gap, current are in casing from lower gap
Middle outflow；During sorting lower floor fry, flowing water is poured at described lower gap, current are flowed out in casing from upper gap.
The invention has the beneficial effects as follows, it is compared with the prior art, simple structure, is carried out by the structure to fry separatory vessel
Optimization design, by the height for adjusting gap, can adjust sorting specification, realize dividing for different size fry with a separatory vessel
Choosing, reduces number of devices；In method for separating step be improved and innovate, the characteristics of water layer is perched according to fry, use
Stimulation by running water makes fry adverse current swim out of by separatory vessel gap, slightly larger fry voluntarily can lean to one side to swim out of individuality, it is to avoid fry
In screening, fish body easily squeezes the larger problem of wound, death loss, it is adaptable to the especially tender and lovely high-level fish seed of some physique point
Selection operation, improves the economic benefit of famous-brand and high-quality aquatic products kind nursery industry.
