Abstract
A fresh water fish fry incubator is characterized in that: a box body (1) is open; the upper part of the box body (1) is provided with a water inlet valve (2), and the lower part is provided with a water outlet valve (3); two inner edges of the bottom of the box body (1) and a front edge and a back edge of the box body (1) are provided with separating strips (4) which are in one-to-one symmetry; and meshes (5) are provided above front and back separating strips (4) of the box body (1) or at the clearances of the upper surfaces of the lower surfaces of the separating strips (4). The fresh water fish fry incubator provides incubating condition for the viscous eggs or demersal eggs, thereby facilitating observation and research.
Description
Technical field
The utility model relates to the fry hatching device.
Background technology
Reform and open up to the outside world over 30 years, the fresh water fishery of China has obtained bigger development, and wherein the success of artificial propagation techniques and popularization play the important and pivotal role.It is master's traditional pattern that freshwater aquiculture has been broken with " green grass or young crops, grass, silver carp, flathead " four large Chinese carps, and some famous-brand and high-quality aquatic products have formed certain scale.But in the hatching process of fry, all continue to use the hatching facility of four traditional large Chinese carps all the time, invest greatlyyer, and need certain auxiliary facility.The present mode of production mainly contains following deficiency: (1) existing cement pit cost is high, and promoted extension is limited, and certain degree of difficulty is arranged; (2) the bad ovum in the hatching process, the egg membrane that comes off easy-clear not, the stability of influence hatching water quality; (3) be not easy to observe, along with the carrying out of hatching, water quality begins muddiness, can not well observe the growth course of fish-egg in cement pit; (4) when carrying out small-scale test, because the hatchery, the hatching facility all is used to produce basically, and specification is bigger, and negligible amounts is unfavorable for carrying out scientific research; (5) during fry hatching, begin test, when embryo collection was grown sample, because the water quality of hatching is relatively poor, the embryo received certain pollution, can not satisfy the needs of scientific research.
Summary of the invention
The purpose of the utility model is to provide a kind of freshwater fish fry hatchibator, and it is a kind ofly can satisfy the hatching freshwater fish viscid egg of scientific research, production and the device of demersal egg fish.
The technical scheme of the utility model is:
The utility model is an open type casing; A water intaking valve is arranged at the top of casing; An outlet valve is arranged at the bottom, and the inside, bottom of both sides casing is just, there is one by one the parting bead of symmetry inside, both sides, back, casing just, the net sheet is arranged in the gap, top and bottom of the top or parting bead of both sides, back parting bead.
Casing is processed by lucite.
The advantage of the utility model is following:
1, the utility model can be hatched the freshwater fish viscid egg, can hatch the demersal egg fry again.
2, the utility model can satisfy the requirement of hydrostatic hatching, can satisfy the requirement of flowing water hatching again.
Simple, convenient when 3, the utility model is bred, labour intensity is little.
4, the utility model during incubation is convenient to observe, and is beneficial to sampling.
5, the utility model can in time carry out blowdown according to change of water quality between the incubation period and hatching situation, optimizes incubation condition, improves the incubation rate of fry.
6, the utility model can be made the incubator of different size and quantity according to the different needs of scientific research, production, and the utility model can move, and can meet the different needs.
7, it is convenient that the utility model is collected fry, and the damage of fry has still less improved survival rate.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, the utility model is described further.
Among Fig. 1: casing 1 is processed by lucite, and the top of casing 1 is an open type, and a water intaking valve 2 is installed on casing 1 top; An outlet valve 3 is installed in the bottom, the bottom surface of water tank 1, just, corresponding one by one parting bead 4 is respectively arranged in the back; Net sheet 5 has been placed in the gap of parting bead 4 vertically, is placing the viscid egg of viscosity egg fish on the net sheet 5, can hatch; If when needing the flowing water hatching; Through the water intaking valve 2 control inflows on control water tank 1 top, the draining valve 3 of control water tank 1 bottom, only the two advance, drainage discharge are kept balance and can be realized.When changing water, open the draining valve 3 of casing 1 bottom, the water intaking valve of opening again behind effluent sewerage and the impurity above the casing 12 can inject new water.
Behind the fry hatching, when needing to collect fry, open the outlet valve 3 of casing 1 bottom, fry is just discharged from drainpipe.
Among Fig. 2: casing 1 is processed by lucite, and the top of casing 1 is an open type, and a water intaking valve 2 is installed on the top of casing 1; A draining valve 3 is installed in the bottom; The bottom surface of water tank 1, just, there is parting bead 4 one to one inside, back, just, net sheet 6 in placing flat on the parting bead 4 of back; The viscid egg of demersal egg of demersal egg class fish or viscosity egg fish is placed on the net sheet 6, can hatch.
Claims (2)
1. freshwater fish fry hatchibator; It is characterized in that: casing (1) is open type; A water intaking valve (2) is arranged at the top of casing (1); An outlet valve (3) is arranged at the bottom, and inner both sides, casing (1) bottom and casing (1) are just, there is the parting bead (4) of symmetry one by one inside, both sides, back, casing (1) just, there is net sheet (5) in the gap, top and bottom of the top or parting bead (4) of back both sides parting beads (4).
2. a kind of freshwater fish fry hatchibator according to claim 1 is characterized in that: casing (1) is processed by lucite.
