Description
Technical field
The utility model relates to a kind of hatching apparatus, is specifically related to a kind of sturgeon hatching apparatus based on nursery pond, belongs to technical field of aquaculture.
Background technology
Sturgeon is that the bodily form is large in existing fish in the world, the life-span long, the most ancient a kind of fish, and some kind wherein belongs to rare the watching for animals of country.Domesticly improve its population quantity in order to continue the population of sturgeon, carry out scientific research and production test, carried out artificial breeding and the cultivation of sturgeon in some scientific research institutions and production unit.
But the cultivation of sturgeon is the seed production phase particularly, technical requirement is high, difficulty is large.To realize the key technology that sturgeon population quantity increases and produces to the artificial breeding of sturgeon all the time.Sturgeon food ration is large, and growth rate is slow, grows up to parent population and needs the several years time of more than ten years even, therefore sturgeon lay eggs process be difficult to, in order to make full use of the parent population that lays eggs, reduce the sturgeon required expense of growing seedlings, the incubation rate that improves sturgeon ovum is a ring very important in sturgeon research and production.And sturgeon ovum is demersal egg, apply the seedling-cultivating method of traditional fresh-water fishes, at the bottom of tending to occur sturgeon ovum sedimentation basin, cause the necrosis of a large amount of sturgeon ovum that the situation of saprolegniasis even occurs, seriously restrict the success of growing seedlings.Therefore the sturgeon success rate of growing seedlings is all the time all very low, even if there is the successful story of growing seedlings on a small quantity, incubation rate is not high yet.
Although, the artificial method that sturgeon demersal egg minimizing sturgeon ovum deposits of stirring of current Ye You R&D institution's trial, but this process need stirred one time water body every three or five hours, not only consume a large amount of manpowers, stirring repeatedly also easily makes the breakage of sturgeon ovum, also can there is cannot hatch because accepting a large amount of extraneous stirrings the situation of seedling in some unbroken fish-eggs, although therefore the more traditional method of not carrying out manual intervention of incubation rate wants high, also unsatisfactory.
In addition, after sturgeon fry hatches out, toward contact need to utilize the instrument of fishing for manually from hatchery shift sturgeon fry to nursery pond, due to sturgeon fry in transfer process, be subject to external environment and manually-operated stress, tend to cause the death of some sturgeon fries.
Therefore, improve sturgeon hatching apparatus, improve sturgeon ovum hatching technique, reduce the stimulation in hatch fish roe process, avoiding the unnatural death of fish-egg in hatching process, improve the survival rate after sturgeon fry is hatched, is key technology in the urgent need to address in sturgeon seed reproductive process.
Summary of the invention
The utility model object is to provide a kind of sturgeon hatching apparatus based on nursery pond, to overcome the deficiencies in the prior art.
A sturgeon hatching apparatus based on nursery pond, comprises that bottom is provided with the nursery pond of discharge outlet.For sturgeon seedling raising process is carried out smoothly, comprise that is arranged in a nursery pond hatching main body for the drum-shaped of water body at the middle and upper levels.For lasting water body supply being provided to hatching main body, by supplying water and stir sturgeon ovum wherein toward hatching main body, prevent deposition, be at one end provided with the inlet channel that inserts from top to down hatching main body.For power being provided to water supply and output rationally being controlled, this inlet channel other end is connected with valve and water pump.In order to make to add the water in hatching main body to discharge after stirring sturgeon ovum, and swim into nursery pond with current after sturgeon fry hatches out, be provided with delivery port at the upper side of hatching main body.In order to promote flowing of water body, the sturgeon fry that the water body in discharge nursery pond enters in nursery pond after not allowing and hatching is simultaneously escaped from from discharge outlet, and at nursery pond internal drainage mouth, place is inserted with an outlet conduit, and the below, side of this outlet conduit is provided with perforate.In order effectively to control the water level in nursery pond, be convenient to reasonably draining, be with a sleeve pipe of controlling water outlet water level in the perforate periphery of outlet conduit.
The feature that is demersal egg for sturgeon ovum, for when the seedling raising process, stirs sturgeon ovum by effective water supply from hatching main body below and avoids its deposition to stick, and above-mentioned inlet channel is inserted into following position, hatching main body middle part.
The utility model is to be the feature of demersal egg in conjunction with sturgeon ovum, and to reduce to greatest extent the artificial stimulation in sturgeon hatch fish roe and seedling raising process, improving sturgeon ovum hatching success is target, a kind of sturgeon hatching apparatus based on nursery pond designing and producing.This device is by utilizing water supply link to realize water inlet flushing to sturgeon ovum from hatching main body below, and soft current can make sturgeon ovum current downflow on hatching in main body, promote the hatching of fish-egg.Sturgeon ovum is constantly rinsed to the stirring bringing and avoid making sturgeon ovum to be deposited in hatching main body, constantly water body flow has been improved the external environment condition of sturgeon hatch fish roe, has reduced the necrosis rate of fish-egg in traditional hatching process, has improved the incubation rate of fish-egg.After sturgeon fry hatches out, by controlling water pump and valve increased water flow speed, fry is swum out of from the outlet of hatching main body along current, enter in nursery pond, this process can impact fry hardly, has greatly improved the survival rate in transfer process after fry hatching.The design of controlling water level in nursery pond by sleeve pipe being provided with in nursery pond also makes draining more convenient, has improved production efficiency.
