Description

A kind of three-layer stereo formula fry hatching frame

Technical field

The utility model relates to a kind of fry hatching frame, especially a kind of three-layer stereo formula fry hatching frame.

Background technique

The hatching process of fry: fertilized eggs-prelarva-fry, fertilized eggs need to be put into hatching barrel and are hatched, after having hatched It is transferred to temporarily feeding basin to be cultivated, alevin stage relies primarily on yolk as nutrition, finishes, is developed to one from yolk bag absorption Until the fin ray of fixed number amount, it is transferred to fry pond and carries out the nursing that feeds intake.

During the hatching, cultivating of fry, need that water body is kept to have mobility, on the one hand static water body makes fry Aggregation leads to frictional impact between fry, reduces the survival rate of fry, and on the other hand, dissolved oxygen is insufficient in static water body, causes The hypoevolutism or even death by suffocation of fry, currently, common fry hatching breeding apparatus is mostly circular hatching channal, and there are following Insufficient: although (1) can be that water body has certain mobility, to realize water body flow, water consumption be big, at high cost；(2) when Occur not clearing up in time when dead ovum dead fish seedling in circuit, the sprawling of water mo(u)ld is caused, to impact to healthy fry； (3) time order and function of each hatchery into ovum is different, the early fish-egg morning demoulding hatched into hatchery, and the egg membrane being discharged into water is molten Solution enzyme enters the hatchery of rear fish-egg with recirculated water, and the fish-egg that hatchery is put into after causing shifts to an earlier date demoulding, and demoulding is more in advance Occur to occur in the tail fin of embryonic development to this period muscle effects phase, egg membrane rupture or dissolution, loses egg membrane protection Idiosome sinks under water and dead.

Further, the caliber of the feeder pipe A is less than feeder pipe B, and the caliber of the feeder pipe B is less than feeder pipe C.

Further, the volume of the hatching chamber is less than temporarily feeding basin.

The application method of the utility model:

1, purified clear water is injected in reservoir by pipeline, water temperature is controlled at 25-30 DEG C, opens suction pump, it will Water in reservoir is pumped into feed cistern, and the water in feed cistern flows into hatching chamber by water supply branch pipe, when the water of hatching chamber is filled to 2/3 Afterwards, water supply branch pipe water flow velocity is adjusted by solenoid valve A, control water flow velocity is in 0.1m/s, while opens solenoid valve B, and controls stream Speed is consistent with solenoid valve A, hatches intracavitary water and flows into temporarily feeding basin, and temporarily water extra in feeding basin passes through through-hole overflow to storage pond, holding pond, When the water of storage pond, holding pond reaches the water level of overflow pipe A, fry pond is flowed by overflow pipe A, the water in fry pond reaches overflow pipe B's When height, reservoir is flowed by overflow pipe B, to realize that water recycles.

2, fish-egg hatching barrel is put into hatch, after the fish-egg in hatching barrel is hatched into prelarva, manually opened gate valve A Prelarva is discharged into temporarily feeding basin by feeder pipe A, adds water in the hatching barrel after blanking again and throws ovum, carry out next round hatching, Since the degree of the hatch fish roe in each hatching barrel is inconsistent, so hatching barrel carries out blanking one by one according to the degree of hatching, and And ovum is thrown after blanking；

3, after Larval is at fry in temporary feeding basin, fry is discharged into fry by feeder pipe B by manually opened gate valve B Concentration nursery is carried out in pond, since the Larval degree in each temporarily feeding basin is inconsistent, so the degree according to development is temporary one by one Support basin carry out blanking, after blanking according to the hatching situation of fish-egg in corresponding hatching barrel carry out investment prelarva or temporarily it is vacant；

4, after the fry growth in fry pond reaches standard, carrying ladle is pushed into below feeder pipe C, it is logical to open gate valve C It crosses feeder pipe C fry is discharged into carrying ladle；

5, a small amount of dead ovum, dead prelarva and dead fish seedling are such as found, dead ovum, dead prelarva and dead fish seedling are pulled out in time, avoided The sprawling such as water mo(u)ld, pollutes water body environment, thus unhealthful ovum and fry, if discovery hatching barrel, temporarily feeding basin or When occurring a large amount of extremely ovum and dead prelarva in fry pond, basin is supported by entire hatching barrel and temporarily by feeder pipe A and feeder pipe B in time Water in interior fish-egg and prelarva and corresponding hatching chamber, temporary feeding basin all empties, and adds water again again after handling and throw ovum.

The utility model has the following beneficial effects: hatchery is separated into multiple hatching chambers by demarcation plate by (1), it can be to every A hatching barrel is individually cultivated, and is prevented due to different into the time of ovum in each hatching barrel, early to put into hatching barrel The egg membrane lyase that the fish-egg of demoulding is discharged into water puts into the fish-egg of hatching barrel after entering with recirculated water, hatching is put into after causing The fish-egg in pond shifts to an earlier date demoulding, so that the idiosome for losing egg membrane protection sinks under water and dead, reduction hatching rate；(2) pass through circulation Water carries out hatching, cultivating, keeps dissolved oxygen in water sufficient, avoids reducing hatching rate due to anoxic in hatching process, and can reduce water Dosage, energy conservation and environmental protection；(3) by being provided with hatching barrel, temporarily feeding basin and fry pond on frame body, three-layer stereo formula knot is constituted Structure can complete the hatching, cultivating process of a complete fry, reduce the link of intermediate transfer, and realize recyclable incubate Change, temporarily feeding basin can be directly entered after the completion of the hatching in hatching barrel and is cultivated, then puts into new fish-egg in hatching barrel, from And hatching efficiency is improved, reduce production cost；(4) occurs dead ovum, dead in feeding basin and fry pond when hatching barrel, temporarily When prelarva and when dead fish seedling, dead ovum, prelarva and fry are pulled out, prevents that water mo(u)ld etc. is avoided to spread, dirt is caused to water body environment Dye, thus unhealthful ovum, prelarva and fry, to improve hatching rate.
