Abstract

The utility model discloses an omnidirectional water circulation fish oosperm incubator, which relates to a fish oosperm incubator. The omnidirectional water circulation fish oosperm incubator mainly comprises a buoyant ring (1), a screen cloth cylinder (2), a pressure pan (3), a bottom basin (4) and a water inlet pipe (5), wherein the buoyant ring (1), the screen cloth cylinder (2) and the bottom basin (4) are connected with each other in turn from the top down; the upper part in the bottom basin (4) is provided with the pressure pan (3) which is fixed through bolts (7); and the bottom of the bottom basin (4) is provided with the water inlet pipe (4) which is fixed through a fastener (6). The omnidirectional water circulation fish oosperm incubator has the advantages that the omnidirectional water circulation fish oosperm incubator has a simple structure and light weight and is convenient to store, move and carry; no dead angle exists as for water circulation, thereby improving the hatchability of oosperms; and the overflow area is increased and egg membranes can not be adhered to a water filtering screen cloth under the condition of stripping of fish eggs, thereby the screen cloth is not required to be washed and is convenient to use and the cost and the physical strength are saved. Moreover, the omnidirectional water circulation fish oosperm incubator is suitable for effectively hatching fish oosperms due to high price performance ratio.

Description

The fishes oosperm hatcher of comprehensive water circulation

Technical field

The utility model relates to a kind of fish oosperm hatching apparatus, relates in particular to a kind of fishes oosperm hatcher of comprehensive water circulation.

Background technology

Aquaculture be human use's water resource develop the economy, improve dietary structure, uplift the people's living standard the important channel; Promoting and utilize aquaculture technology, then is aquaculture scientific worker service society, the responsibility that promotes the well-being of mankind and obligation.

In aquaculture technology, the hatching of fish oosperm is important step wherein, and is most important to the quality that improves the fish oosperm hatching.Fertilized egg can be placed in the different vessels hatches, and both can hatch by hydrostatic in net cage, also can adopt running water hatching in hatching cylinder, incubation tank, nursery pond.

Existing hatching cylinder is many to form with the ceramic cylinder transformation of the way, as Fig. 1,2, mainly comprises cylinder body, water strainer sheet, square and water inlet pipe, is a kind of economy, convenience, effect hatching apparatus preferably, is fit to small-scale production; Its melt water amount 200～400Kg can be put fertilized egg 40～1,000,000.But its water circulation has the dead angle, causes fish-egg to stick in a big way the casing wall and the success rate of influence hatching; Because the discharge area is little, and egg membrane easily sticks on the water strainer sheet when causing the fish-egg demoulding, stop up mesh again, fish-egg or fry are overflowed outside the cylinder, bring about great losses.

Summary of the invention

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect that existing hatching cylinder exists, and a kind of fishes oosperm hatcher of comprehensive water circulation is provided.

The purpose of this utility model is achieved in that

Mainly comprise buoyancy ring, screen cloth tube, setting-out dish, end basin and water inlet pipe;

From top to bottom, buoyancy ring, screen cloth tube and end basin are connected successively;

In end basin, its top is provided with the setting-out dish, fixes by screw; Its bottom is provided with water inlet pipe, fixes by securing member.

Operation principle of the present utility model is:

The utility model (one or more) is placed in the hatching water body (cement pit or pond), because the action of gravity of the buoyancy of top buoyancy ring and lower bottom basin etc. is opened the screen cloth tube automatically;

Fish-egg is placed in the screen cloth tube, builds square again and get final product;

Open the water inlet pipe valve, because the impulse force of water inlet pipe and the drag effect of setting-out dish make the comprehensive circulation of running water, no water circulation dead angle in the screen cloth tube, fish-egg is in the good dissolved oxygen environment; Again because the discharge area is big, under the momentum effect of water inlet, egg membrane can not stick on the screen cloth tube and stops up mesh during the fish-egg demoulding.

After hatch fish roe was finished, discharging water collected.

The utlity model has following advantage and good effect:

1, simple in structure, in light weight, be convenient to collection, move and carry;

2, water circulation does not have the dead angle, has improved the fertilized egg hatching rate;

3, increased the discharge area, egg membrane can not stick on the drainage screen cloth when the fish-egg demoulding, therefore need not scrub screen cloth, and is easy to use, provides cost savings and muscle power.

In a word, because the utility model ratio of performance to price height is applicable to effective hatching of fish oosperm.
