Description
Technical field
The present invention relates to the artificial propagation engineering device technique field of fish, specifically a kind of general hatching of semi-submersible type viscous roes
Method and device.
Background technology
In fertilized fish roe hatching process, heavy property fish-egg is deposited in the bottom since the proportion of itself is larger, mutually squeezes,
It easily causes to damage, while mutually accumulation makes fish-egg that can not obtain sufficient dissolved oxygen, causes hatching rate relatively low, prelarva is abnormal
The problems such as form quotient is high.Existing hatching pattern be by the viscous roes that fish are fertilized directly spill palma in water,
On the attachments such as mesh sheet or basin bottom, it is allowed to adhere to directly hatching naturally.The mode of normal point is using hatching frame or hatching
Slot etc. only relies on and the methods of increases the quantity of aeration stone, reduces hatching density, can not really solve the problems, such as that fish-egg is accumulated, separately
One side incubation equipment facility volume is big, takes up a large area, and water consumption is high, and complicated for operation, difficulty is big, and hatching efficiency is low, greatly
The success rate of heavy property hatch fish roe is constrained greatly.Common incubator/cabinet in recent years, using the side for reducing hatch fish roe density
Method alleviates the problem of fish-egg dissolved oxygen deficiency to a certain extent, but its volume is big, takes up a large area, and operation difficulty is big, valence
Lattice are expensive, cannot be satisfied the demand of common nursery.
However the prior art has the disadvantage that：First, the ovum grain being adhered on attachment is unevenly distributed, it is viscous to be easy aggregation
It is attached to cause hypoxia death, the Large Scale Death of ovum grain but will be caused after growth water mold；Second is that the Water space of hatch fish roe utilizes
Rate is not high, easily leads to the water quality deterioration and anoxic of local water body, in turn results in artificial incubation failure；Third, the hatching rate of fish-egg is not
Stablize, is unfavorable for the lasting large-scale production of fry and is effectively reduced production cost.
Invention content
The object of the present invention is to provide a kind of incubation space that can be reasonably distributed ovum grain, efficiently utilize the hatching of fish-egg
Water body and raising and the hatching rate for stablizing fish-egg, to reduce the production cost of fry, it is ensured that the lasting scale of fry
The general hatching method of semi-submersible type viscous roes and device of production.
To achieve the goals above, the technical solution adopted by the present invention is：
A kind of general hatching method of semi-submersible type viscous roes, comprises the following steps that：
（1）Fish-egg prepares：Viscous roes are placed in container, and it is 0.3% sodium chloride solution and hero that mass percent, which is added,
Property milt, stir 40-60 seconds, per 50-100 milliliter fish-egg be added male fish sperm be 0.5-1 milliliters, addition
The amount of 0.3% sodium chloride solution is 5-10 milliliters；
（2）Fish-egg attachment hatching mesh sheet：Hatching apparatus is placed in the water in pond, is in semi-submersible type, hatching apparatus is in partly latent
Formula refers to that a hatching apparatus part sinks to underwater, and another part is exposed on the water surface.One people is in spilling the viscous of after fertilization on the water surface
Property fish-egg, the continuous left and right horizontal of handle that another people hauls hatching apparatus shakes hatching apparatus, passes through water fluctuation and hatching net
Piece movement makes fish-egg be uniformly dispersed to be adhered in the hatching mesh sheet of hatching apparatus；60 × 40 centimetres every of hatching mesh sheet is spilt
Viscous roes after 50-100 milliliters of insemination；
（3）Hatch the suspension of mesh sheet：The hatching mesh sheet of uniform adhesion viscous roes is taken out from hatching apparatus, it is vertical whole
It hangs on the lanyard in water together, hatches mesh sheet interval 15-20cm, the hatching mesh sheet quantity of average every cube of water body suspension is 3-
5；
（4）Hatching management：To in pond water carry out aeration aerating, keep pond in water oxygen content be 4-5 milligrams/
It rises, water temperature is controlled at 18-25 DEG C, and per a water is changed within 3-5 hours, flow cavitation result is at 3-5 cubes m/h, you can in 2-5 days
It hatches.
The hatching apparatus that the general hatching process of semi-submersible type viscous roes uses, including handle, wooden frame, wooden bottom frame and
Hatch mesh sheet, the handle be mounted on transparent wooden frame both ends, transparent wooden frame partly latent in water,
Wooden bottom frame is arranged in transparent wooden frame lower part, and hatching mesh sheet is placed on wooden bottom frame.
The hatching mesh sheet, including mesh sheet, iron frame and hook, mesh sheet are fixed in iron frame, hook installation
On iron frame, hook can rotate on iron frame.
The mesh sheet is made of polyethylene, and width of mesh is 80 mesh.
The general hatching method of semi-submersible type viscous roes and device of the present invention, hatching method is simple, and device setting is ingenious, knot
Structure brief and practical using this hatching apparatus and combines corresponding application method, can effectively improve the distribution consistency degree of hatching fish-egg,
Hypoxia death caused by avoiding ovum grain from stacking, and the harm for hatching common saprolegniasis to ovum grain is reduced, further increase fish-egg
Hatching rate；Being designed with conducive to Water space utilization rate is greatly improved for suspension type iron side hatching mesh sheet, it is extensive convenient for carrying out
Fry hatching produces；This hatching apparatus production method is simple, raw material are easily looked for, and overall cost is relatively low.The main base of this hatching apparatus
It is designed, the self-characteristic with particular reference to viscous roes and environment of hatching condition, such as fish in breeding biology of fish principle
Ovum grain is freely scattered with flow is adhered on object rough surface in water after inseminatio externalis, to which semi-submersible type hatching is produced in design
Mesh sheet is hatched on device frame and hangable iron side, splashes fish-egg by artificial insemination and the artificial hatching apparatus that shakes manufactures flow
Fish-egg is set to be uniformly distributed in mesh sheet.By applying this hatching apparatus, carp, crucian, Pelteobagrus fulvidraco, oblique jaw have successfully been hatched
Silver xenocypris, ussuriensis, Su Shi justify abdomen（Fish awns）Etc. the seed of a variety of viscid egg grain fish, significant effect.Wherein, abdomen is justified to Su Shi
（Fish awns）Ovum grain carry out hatching test monitoring, find hatching rate improve at least 20% than traditional hatching method, reach 80%
More than, pond hatching density is improved by 10,000 original tails/m3 to 60,000 tails/m3, hatches 20,000,000 tail of kind fry or more year,
Realize the large-scale production of the rare kind of fish.
