Abstract
The utility model relates to a fish hatcher, which belongs to the technical field of aquaculture. The fish hatcher is specially used for hatching floating and drifting eggs. The fish hatcher comprises a hatcher body, a bottom support net, a water change sieve pipe and an air regulator, wherein the hatcher body is a conical barrel, the bottom support net is arranged on the conical section of the hatcher body, the upper part and the bottom part of the hatcher body are respectively provided with a water inlet opening and a water outlet pipe, the air regulator is arranged above the bottom support net, and the water change sieve pipe connected with the water outlet pipe is also arranged in the center in the hatcher body. The fish egg hatcher of the utility model is used for hatching floating and drifting eggs of fish, and can obviously improve the hatching rate. Since the water flowing hatching mode is adopted, the fish egg hatcher provides the most proper hatching conditions such as the dissolved oxygen, the water flow and the like for fish eggs. When being applied to artificial fish propagation, the fish egg hatcher effectively overcomes the defects of instable water quality, easy bottom sinking and death of floating eggs and the like of a still water hatcher.
Description
Technical field
The utility model belongs to the fish incubator in the technical field of aquaculture, is specifically designed to buoyancy, the hatching of drift gamogenetic egg.
Background technology
From nineteen fifties; since having broken through artificial propagation of fish with the Chinese science man of Zhong Linwei representative; kind of fish had been realized artificial propagation surplus the whole world had had 200; fundamentally solved dependence to the native species seedling; not only greatly promoted the development of culture fishery; for the mankind provide the protein of high-quality, and established technical foundation for the protection of the stock of fish and propagation.In the artificial propagation of fish process, incubating oosperm is extremely important sport technique segment, directly influences the quality and the quantity of newly hatched larvae.In fish buoyancy, the hatching of drift gamogenetic egg, generally take the dual mode hatching, a kind of is outdoor cement pit circuit flowing water hatching, another kind is the hatching of hatching pail hydrostatic.Though the former hatching amount is big, conditions such as illumination, temperature are difficult to control, land occupation, and water consumption is big, the power cost of drawing water height; The latter is owing to take the hydrostatic hatching, and hatching later stage water quality is relatively poor, and easy unboiled water was mould when water temperature was low.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency that above-mentioned prior art exists, a kind of novel fish incubator to be provided.
For achieving the above object, the technical scheme that the utility model is taked is: this fish incubator comprises incubator main body, collet net, changes water sieve pipe and air regulating device, described incubator main body is conical bucket, be provided with the collet net for one section in its taper, top and bottom are respectively equipped with water inlet and outlet pipe; Described air regulating device is arranged on the top of collet net; Central authorities also are provided with and change the water sieve pipe in the incubator main body, are connected with outlet pipe.
Describedly change the hollow circular cylinder that the water sieve pipe is the metallic support structure, be with 150-250 mesh sieve thin,tough silk outward.
Described collet net is circular, and flange is a metal, and mesh is the 150-250 order.
Described air regulating device is by gas stone, and tracheae and control valve are formed, and gas stone connects tracheae, and tracheae stretches out outside the incubator main body, and control valve is installed on the tracheae.
Fish hatcher of the present utility model is used for the hatching of fish buoyancy, drift gamogenetic egg, can significantly improve incubation rate.This fish hatcher has used the flowing water hatching pattern, and incubation conditions such as optimum dissolved oxygen, current are provided for fish-egg.This fish hatcher is applied to artificial propagation of fish, and the water quality instability, the drift gamogenetic egg that efficiently solve the existence of hydrostatic incubator easily sink to the bottom defectives such as death.The utlity model has the comparison extensive market prospects, the annual requirement of estimating The South China coastal is more than 50,000 covers.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Fish hatcher of the present utility model as shown in Figure 1 comprises incubator main body, collet net, changes water sieve pipe and air regulating device, and described incubator main body 2 is a conical bucket, at its conical section collet net 4 is set, this collet net 4 is circular, and flange is a metal, and mesh is 200 orders; Be provided with water inlet 1 on the top of incubator main body 2, the bottom is provided with the outlet pipe 7 of belt switch 5, and the mouth of pipe of water inlet pipe and outlet pipe directly is 2-3cm; Air regulating device 10 is housed above described collet net 4, and this gas conditioner is made up of gas stone 6, tracheae 9 and control valve 8, and gas stone 6 connects tracheae 9, and tracheae 9 stretches out from incubator main body 2 tops, and control valve 8 is installed on the tracheae 9; Central authorities also are equipped with and change water sieve pipe 3 in the described incubator main body 2, are connected with outlet pipe 7, and this changes water sieve pipe 3 and is the hollow circular cylinder of metallic support structure, is with 200 mesh sieve thin,tough silk outward.
During use, water-changing tube 3 is inserted in the outlet pipe 7, open the beginning of water inlet 1 and in incubator main body 2, inject clean hatching water, the water surface is apart from the about 2cm of water inlet, open control valve 8 and inflate, open the switch 5 of outlet pipe 7, regulate the current size of intake-outlet by gas stone 6, keeping stable level, and to make incubator rate of water exchange hourly be 25%--30%; By certain density fish is put into incubator and hatch, the gas output that regulates control valve 8 makes the water surface be the microvesicle shape, hatches until fry.Before putting seedling, take out and change water sieve pipe 3 and collet net 4, close the switch of valve water inlet, fry is flowed out from the outlet pipe 7 of bottom, collects fry.
