Description
Technical field
The present invention relates to technical field of aquaculture, more particularly to a kind of leech hatching apparatus and mating system.
Background technology
Leech is commonly called as leech, leech, ox leech etc., and the alias of various regions is a lot, and most peasants both know about, and leech is always
Be grown in rice terrace, pond, among creek, it is a kind of well sold and in short supply rare traditional Chinese medicine raw material both at home and abroad, is stimulated the menstrual flow with blood-breaking,
Disperse accumulations dissipates the effect of stasis of blood, subdhing swelling and detoxicating and induced abortion.Research in recent years finds, leech to tumour, hepatitis and angiocardiopathy all
There is significant curative effect.
Known leech has kind more than 600 in the world, and just there are tens kinds, but medicinal mainly expanded letter gold thread in wherein China
Leech, hiruto and doctor leech, the artificial farming of these three leech at present has obtained initial success, but still suffers from many deficiencies.Mesh
The breeding spawning of preceding leech be all using it is imitative it is wild have a cubic metre of earth formula, i.e., in hirudiniculture environment, manually built and be higher by with soil
The spawning platform of the water surface, leech is allowed voluntarily to pierce mating in the soil of spawning platform, spawning.After leech lays eggs 10 ~ 20 days, people
Work excavates platform soil, takes out the ovum cocoon of leech production, then ovum cocoon is concentrated to hatch and come.
The following many drawbacks of this mode with the presence of local products ovum：Need to spend a large amount of human and material resources chessons and build
Make spawning platform；In irrigation and drainage not in time or when raining heavily, spawning platform exists to be submerged and causes leech and the dead risk of ovum cocoon；
The leech parent death rate is higher after spawning, typically at more than half；The soil of spawning platform is easily hardened, and leech is pierced in soil
Spawning is very laborious, while spawning also consumes one's strength very much in itself, therefore leech is often powerless after laying eggs drills out soil again, in addition soil
In often have the harmful organisms such as spider, cause leech and ovum cocoon injures and deaths；After leech lays eggs in soil, artificial side can only be used
Method, soil is carefully excavated, take out ovum cocoon, moreover, excavated by manual work cocoon is time-consuming, laborious, be also easy to cause ovum cocoon to damage；Further, since
The abuse of agricultural chemicals, chemical fertilizer etc. in recent years, causes natural environment seriously to be polluted so that leech of the cultivation in pond or puddle
Living environment be seriously damaged, cause its hatching speed to slow down, incubation rate reduce.
Chinese patent discloses the method that some leech breed without soil, such as Application No. " 201310586156.8 ", patent
The patent of invention of entitled " method of artificial soilless leech hatching ", although patent of the present invention overcomes the above has local products ovum to survive
The shortcomings that rate is low, hatching speed is slow, but still have the following disadvantages：The incubator inner structure for hatching Whitmania pigra Whitman spawns is complicated；In leech
Ovum cocoon hatches after seedling, also needs that manually leech seedling is transferred in box for breeding or culturing pool and is cultivated, and seedling can be caused to turn
Shifting is not in time, transfer efficiency is low, allows and takes the deficiencies of artificial.
The content of the invention
It is an object of the invention to overcome the defects of above-mentioned technology and deficiency, Whitmania pigra Whitman spawns survival rate and leech parent are improved
This rate of recovery, solve leech seedling transfer inconvenience, the easily technical problem such as escape in the prior art, and propose a kind of leech and incubate
Makeup is put and mating system.
A kind of leech hatching apparatus and mating system, including closed chamber, the support in closed box room, located at support
On incubator, it is structurally characterized in that：The closed chamber is provided with outlet；The rack arrangement in the closed box room, in
Between be provided with passageway, the support is provided with multiple object-putting layers；The incubator includes casing and screen frame, and the casing is placed in support
Object-putting layer on, the screen frame is set up in casing, screen frame bottom be provided with several can leak through leech seedling but can not leak through
The through hole of Whitmania pigra Whitman spawns.
Preferably, shown closed chamber is container.
Preferably, air curtain is provided with above the outlet of the closed chamber, constant temperature and humidity machine is provided with closed box room；It is described
Screen frame bottom is provided with moisture detector.
Preferably, the bottom of the casing side offers discharge outlet, and it is vertical to be provided with the inside of the casing opposite side
The filter in direction, the filter are connected by the guide rail being secured transverse on cabinet wall with box body-sliding, the guide rail
It is provided with the guide rail buckle for being used for fixing the filter.
Preferably, the bottom half and the distance of screen frame bottom are 30-34mm.
Preferably, in addition to sprayer unit, aqueduct of the sprayer unit including being fixed on object-putting layer bottom are described to lead
Fog-spray nozzle is evenly equipped with water pipe, one end of aqueduct connects with external water source and send water to the aqueduct by water pump.
Preferably, one layer of anti-escape net is equipped with the top of the casing.
A kind of leech mating system, comprises the following steps：
（1）The spawning bottom portion of constant temperature and humidity is laid on using the foam beads after carrying out disinfection as oviposition substrate；
（2）Leech parent is put into spawning case and cultivated, spawning the temperature inside the box is taken the photograph from 20 by described constant temperature and humidity machine
Family name's degree rises, daily 1 degree Celsius of rise, it is stepped up to 25 degrees Celsius, and detect spawning by described moisture detector
Humidity in case, make its humid control 80%（Air humidity）；
（3）When parent is put into spawning case 15 days, after it is taken out together with ovum cocoon, ovum cocoon is put into described screen frame and incubated
Change, while add water into casing, it is 20mm to make the depth of water in casing；
（4）In ovum cocoon 1 ~ 2 day in screen frame will incubation of membrane, and entered by the through hole of screen frame bottom in described casing
Growth, when the leech seedling in casing reaches 1 ~ 20,000, or after leech seedling grows 1 ~ 2 day in casing, move it into
Cultivated in culture pond.
Preferably, it is used as anti-release apparatus along by the use of the nylon wire of 20 mesh on the spawning case.
Preferably, water temperature is maintained at 24 degrees Celsius in the culture pond, and the soil moisture is 21 degrees Celsius in culture pond.
The beneficial effects of the invention are as follows：The leech hatching apparatus of the present invention is simple in construction, after hatching Whitmania pigra Whitman spawns emergence, by
There is hydrotaxis in young leech, can voluntarily be entered in the water of bottom half and grown by the through hole of screen frame, remove what is manually shifted from
Trouble, and it is avoided that loss caused by transfer not in time；Spawning and hatching is carried out using without earthwork formula, a large amount of manpower and materials is reduced and enters
Row chesson, build spawning platform；When effectively avoiding raining heavily, ovum cocoon immersion, ovum are dead caused by management is not in place
Phenomenon occur；Reduce a large amount of manpower and materials and carry out digging cocoon, substantially increase the recovery of parent and the survival rate of ovum cocoon after spawning；
Spawning and ovum cocoon hatching are carried out in closed box room, is easy to temperature control, carries out seed breeding in advance, by properly increasing hatching
Temperature, shorten brooding time, reach seedling and concentrate membrane purpose, while make the membrane time earlier than fish wild seed first quarter moon even one
Month, that improves leech breeds efficiency.
