Abstract
The utility model relates to an upward turning type small-size annular passage loach egg hatching device, which is characterized in that a water supply pool enables treated hatching water to flow out from a duckbilled water outlet into a small-size hatching basin through a pipeline, slow rotating type clockwise direction water flows are formed, an overflow pipe is arranged in the middle of the hatching device, a plurality of small holes are drilled on an iron sheet support cover being more than 3cm higher than the basin bottom on the periphery above an overflow opening of the overflow pipe, and a nylon gauze cover is made by 100-mesh gauzes for sheathing the iron sheet support cover for preventing fertilized eggs from entering a sedimentation pool through flowing out along with the water when the water in the hatching basin overflows. The hatching water is purified through the sedimentation pool, and the acidity and alkalinity is regulated through quick lime and bleaching powder, so the cyclic utilization is realized after the pH value is between 7.9 and 8.1.The equipment is delicate, the operation is convenient, and the cost is low.
Description
Technical field the utility model relates to loach ovum grain hatching apparatus in a kind of aquaculture technology.
Background technology loach fertilized egg hatching is a very important link in the process of artificial propagation loach, and it is directly connected to the success or failure of propagating loach artificially.At present, general artificial propagation loach adopts artificial loach fertilized egg technology to carry out artificial insemination and hatching.Have hydrostatic hatching and flowing water commonly used are hatched dual mode.Incubation equipment generally adopts hatchery, hatching net cage, hatching cylinder, hatching pail, circular hatching channal etc.The hydrostatic hatching is promptly put into the fish nest that is stained with fertilized egg immobilising waters such as hatchery, hatching net cage and is hatched.Flowing water hatching promptly with circulating water or the hatching of microfluidic water, has fertilized egg being placed in hatching cylinder, incubator box or the circular hatching channal of circulating water or microfluidic water and hatches.Circulating water or the hatching of microfluidic water have following several method: attach the hatching of nest flowing water: fertilized egg is attached on the fish nest, puts into the hatching facility and carries out the hatching of miniflow water, and its water velocity is advisable not dash the ovum that falls to being attached on the nest.Go nest flowing water hatching: fertilized egg is taken off glutinous or is not taken off glutinously, grasps flow velocity and puts into hatching facilities such as circular hatching channal, hatching cylinder and hatch.But, since loach fertilized egg the hatching cylinder, hatching pail and circular hatching channal flowing water in, because of the bad regulation and control of flow velocity, and brooding time is longer, it is consuming time to take a lot of work, often hatching effect is undesirable; Also because in the hydrostatic hatching of hatchery, hatching net cage and spawning pond; Often because of there not being fresh water body to flow into, and the time of whole hatching all at this water body, water quality degenerates or anoxic easily; Cause incubation rate low; And existing circular hatching channal facility is huge, and cost is higher, is inappropriate for extensive promotion and application.
The utility model content has some deficiency that loach incubating oosperm facility occurs in the process of artificial propagation now in order to overcome, and the utility model provides the small-sized circuit loach of a kind of upper-turn-type ovum grain incubator.This device can not only reduce the lethality of loach in hatching process significantly, and equipment is exquisite, easy to use, can significantly reduce aquaculture cost.
The utility model solution technical scheme that its technical problem adopted is: the hatching water that will be handled well by feed cistern flows out to each miniature circular incubation vessel through water inlet arm branch and outlet pipe from the duck delivery port through the water inlet person in charge; Form rotary current; Slowly rotation is flowed in the hatching basin, makes the rotation of water clockwise direction.In the middle of circular incubation vessel, leave overflow pipe; The gap of overflow pipe top is higher than that to bore aperture on the above iron plate support cover of 3cm at the bottom of the basin some one week; With 100 order gauzes process that the nylon wire screen covering entangles the iron plate support cover in case when water overflows in the circular incubation vessel fertilized egg flow out with water, get into sedimentation basin and purify.The hatching water purifies through sedimentation basin, regulates acid-base value with quicklime and bleaching powder, and pH value remains between 7.9-8.1, recycles.Meta-alkalescence water quality helps the loach spray body surface secretion mucus protection young and not by other microorganism encroach, also lowers in moving about injured with the living friction of hard produce.Hatching water is through processing the time, if when outside air temperature is lower than 18 ℃, owing to be the saprolegniasis high-incidence season; So, at first will hatch the workshop doors and windows sealing, room temperature is adjusted to about 25 ℃; Then the sedimentation basin water is extracted into hatching workshop feed cistern through activated carbon filtration; With quicklime or bleaching powder regulate water PH value to 8.0 place 12 hours subsequent use, between hatching, one group of quartz burner sterilization is installed simultaneously, circulation in the hatching water is carried out with per 5 square metres; Forbid that extraneous raw water flows into the workshop, so just can need not hatch under the situation of any medicine safely and effectively.Hatching water promptly can be recycled after treatment.
The beneficial effect of the utility model is, in the small-sized circuit loach of upper-turn-type ovum grain incubator, can when improving the water body oxygen content, keep water cleaning, and the optimum condition of loach incubating oosperm is provided, and simple in structure, easy to operate.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is embodiment sketch map of the small-sized circuit loach of upper-turn-type ovum grain incubator.
Fig. 2 is the structural map of the small-sized circuit loach of upper-turn-type ovum grain incubator resistance ovum device.
Among the figure: 1.PPR plastics water inlets persons in charge, 2.PPR three-way plastic tube, 3.PPR plastics intake arm, 4.PPR plastics outlet pipe, 5. duck delivery port, 6. outlet pipe bend pipe, 7. nylon wire screen covering, 8. iron plate support cover, 9. support cover apopore, 10. overflow pipe, 11. circular incubation vessels.
Embodiment is in Fig. 1; Utility model is responsible for the hatching water that (1) feed cistern will be handled well with the water inlet of PPR plastics and is flowed out from duck delivery port (5) through water inlet arm (3) and PVC plastics outlet pipe (4); Be diverted to each miniature circular incubation vessel (11); Form rotary current, make the rotation of water clockwise direction, slowly rotation is flowed in the hatching basin.When hatching water reach a certain height in circular incubation vessel (11); Just flow out through middle overflow pipe (10) from the support cover apopore (9) of circular incubation vessel (11) by the resistance ovum device of nylon wire screen covering (7), iron plate support cover (8) formation; To bore aperture on the iron plate support cover some because of having at the gap of overflow pipe; Fertilized egg was flowed out with water when aperture was processed the nylon wire screen covering and entangled the iron plate support cover and prevented that circular incubation vessel (11) lining water from overflowing with 100 order gauzes again, had guaranteed that loach hatching ovum grain constantly circulates in circular incubation vessel.After refluxing, the hatching water purifies once more through sedimentation basin; And with quicklime and bleaching powder adjusting acid-base value; To reach pH value (meta-alkalescence water quality helps the loach spray body surface secretion mucus protection young and not by other microorganism encroach, also lower the friction of in moving about, giving birth to and disease takes place in injured infection) between 7.9-8.1 with hard produce; Extract recycle again out from sedimentation basin through water pump.
