Abstract

The utility model relates to an incubator for a 'fengnian' insect. By using the utility model, the incubation reaction is uniform, and constant temperature can be kept; thus, the incubation rate of a larva can reach 80-90%. The body of the incubator for a 'fengnian' insect is made of galvanized iron or plastic plates, and the structure of the utility model is simple. A heat traced blowing pipe is inserted into the incubator for a 'fengnian' insect, and the lower part of the incubator for a 'fengnian' insect is provided with an eyelet in which light passes. As the larva has phototaxis, so the larva and the shell can be conveniently separated from each other; thus, pure larva with good quality can be obtained, and when the larva is eaten by fish and shrimp, the high yield of the fish and shrimps can be realized. When the utility model is used, the critical shortage problem that fresh baits of the fish and the shrimp can be solved because of the high yield, and the diseases of the fish and the shrimps can be eliminated; thereby, the utility model has the important meaning for cultivation enterprise of the fish and the shrimp in the China.

Description

Incubator for 'fengnian' insect

The invention relates to the incubation equipment of the good quality and high output of seawater fairy shrimp (halogen worm), this equipment can make the hatching reaction of artemia cysts even, can improve egg hatching rate and reach 80～90%, and the artemia larvae of hatching is separated totally with chorion, the artemia larvae of obtaining is the pure of height.Artemia larvae as fishes and shrimps grow seedlings bait edible after, can avoid the generation of fish and shrimp diseases.

The halogen worm and the young thereof contain abundant vitelloenin and fat, are the fresh bait material of the coastal raising fish and shrimp cause of China.After the halogen worm artificial culture high yield, the development of mariculture cause will be promoted greatly.

Existing halogen worm incubator for daylighting, all adopts the lucite incubator abroad, because the cost height, material shortage has limited a large amount of uses at domestic fishery family.

The domestic cement pit incubator that mostly adopts adopts cement pit before hatching, must be cleared up and sterilize, keep in repair pipeline etc., also will take to be incubated oxygenation and change measures such as water, causes investment high like this, the equipment control complexity.

Another shortcoming is that the cement pit volume is big, and the dead angle is many in the pond, and ovum is deposited on the dead angle more, and the influence hatching is so incubation rate has only more than 40%.Cement pit separates the chorion and the young, and processing is unclean yet, will be mixed with the artemia larvae of chorion, and is also nondigestible after the fishes and shrimps of throwing something and feeding are edible, often causes fish and shrimp diseases and death.

The present invention through conscientiously research, has finished the present invention in order to solve the problem that existing incubator exists finally.

The purpose of this invention is to provide a kind of good incubator, make incubation rate bring up to 80～90%, and can up hill and dale the chorion and the young be separated, remove the murder by poisoning that chorion has, in order to avoid the generation of fishes and shrimps food back disease.

Another advantage is to use cheap galvanized iron sheet or plastics incubator, replaces the lucite incubator, reaches and reduces investment, be beneficial to popularization, and device structure is simple, conveniently moving, and indoor and outdoor all can be used, and is convenient to management.

Incubator of the present invention is made with various suitable material such as galvanized iron sheet or plastic plate, and visor is a glass product, shape and structure such as cutaway view.

1---incubator

2---the glass visor

3---companion's hot blow airduct

4---discharge port

Concrete principle is described as follows:

1, the incubator volume is 1 cubic metre, and body is the garden tubular, and the bottom is a taper, is convenient to the hatching reaction evenly, raises the efficiency.

2, glass visor printing opacity utilizes young phototaxis, and the effect that separates chorion is arranged.

3, companion's hot blow airduct is superimposed by heat pipe and airduct, and the airduct blowing is floated and oxygenation ovum, and heat pipe makes air heat, keeps temperature uniformity.

4, discharge port is the artemia larvae discharge port, is convenient to separate with chorion, so opening is at center, the end.

The function of this incubator can make the hatching reaction evenly at cone, raises the efficiency, warm-air pipe is introduced in the cone from the outside, and hot blast constantly upwards disperses oxygenation from the pipe end Bubbled stone from the bottom, make oophyte can not flow, hot blast can make artemia hatching solution keep constant temperature again.Oxygenation and constant temperature are the essential condition of hatching, after finishing, hatching stops ventilation, chorion floats naturally, at this moment incubator is added a cover shading, and the bottom utilizes young phototaxis because of Visual mirror printing opacity, move about to the bottom gradually, when reaching chorion and thoroughly separate, chorion taken away emit artemia larvae again, so can hatch the artemia larvae of the high yield of high-quality with the young.Learn 1m from embodiment ³The artemia larvae that water body is hatched can supply 23m ³The young shrimp that water body is hatched is edible.

The embodiment of incubator: at first in incubator, add artemia hatching solution, artemia hatching solution adopts the seawater of 15～30% salinity behind the sedimentation and filtration, wherein add 0.1～0.3 milliliter/liter hydrogen peroxide and the vitamin of 3ppm, suitably add magnesia, adjust pH value and keep 8～9, temperature is controlled at 25～31 ℃.As keep constant temperature, can hatch artemia larvae in 1～2 day, incubation rate can reach 80～90%, 1 liter of artemia hatching solution can be put into 5～10 grams through the freezing dry ovum of screening, with companion's hot blow airduct, hot blast constantly from the Bubbled stone air-supply oxygenation of pipe lower end, makes solution that sufficient dissolved oxygen be arranged in the hatching, hot blast is controlled constant temperature not only, can make ovum can not flow again.Improve incubation rate, and can blow down the carbon dioxide gas of generation.

The method that the chorion and the young are thoroughly separated, after finishing, hatching stops ventilation, chorion is taken away above floating to, do not hatch ovum and fall the bottom, when emitting incubator is added a cover shading, the young moves about the end of to because of light is arranged at the bottom, and open outlet will not hatch ovum and the young is put into fresh-water cask, and bucket tilted static three minutes, at the bottom of ovum just sinks to barrel, and the young moves about in water, and young sucking-off, so just thorough and ovum has separated with siphon pipe, young elimination fresh water, the young is moved in the seawater-culture pond, carry out large tracts of land and cultivate, artificial culture halogen worm is than tens of times more than of natural reproduction volume increase.
