Abstract
The utility model discloses a catfish artificial culture device, which comprises a water pool communicated to one end of a culture bowl via a divert tube, wherein the end of the divert tube is provided with a water tap, another end of the culture bowl is provided with a water outlet provided with a fish-egg baffle network. Compared with prior art, the utility model has the advantages of low cot, simple structure, and simple operation, which can arrange the culture bowl number according to zygote number and lay 50-100 thousand zygotes in each culture bowl, with quick production, low production cost, controllable water flow speed, accurate watch and record. The utility model can remove dead seed and remove seed easily, which can artificially add oxygen, to improve seeding amount in unit area, while the seed survival rate can reach at least 95%. The utility model can apply batch production and continuous multiple productions, with wide application.
Description
Technical field
The utility model relates to a kind of fish reproduction technical field, especially relates to a kind of catfish artificial propagation incubator.
Background technology
Catfish is the peculiar famous and precious economic fish in China Huanghe valley by present everybody daily edible economic fish, especially Yellow River catfish, has higher nutrition and economic worth; Along with the breakthrough of its artificial propagation techniques, this kind is propagated artificially by natural fishing in recent years, becomes the new focus of inland waters freshwater fish breed variety day by day.But because fertilization rate, incubation rate and emergence rate in its artificial propagation process are not high, cause the few valency of seedling expensive, seriously restricted the large-scale development of this kind; Incubation equipment then is one of key technique that influences its incubation rate emergence rate; solved this key technique of incubation equipment; also just having solved it influences the bottleneck problem of incubation rate emergence rate, promotes that to carrying out its scale artificial culture the exploitation of fresh water improved seeds is significant.Be that hatch and two kinds of methods of artificial cement circuit hatching naturally in the pond what mainly adopt aspect the catfish incubation equipment at present.Hatch naturally in the pond is the net cage of inserting the certain mesh of certain area in the pond, select gonad development preferably the male and female parent population carry out combo, hasten parturition, put it in the net cage, treat that it oestruses, lays eggs after, pull parent population out, fish-egg is grown in net cage naturally.That the method troublesome poeration, parent population lay eggs is asynchronous, easily eat fish-egg postpartum, pull the parent population difficulty out, be difficult for observing ovum growth, rupture of membranes and the situation of emerging, the back feeding management inconvenience of emerging, be difficult for record statistics incubation rate emergence rate etc.; Artificial cement circuit hatching is that fertilized egg inserting had in the cement circuit of certain flow rate, the hatching of miniflow water, and this method needs to build tank and cement circuit simultaneously, and cost of investment is bigger, be difficult for promoting, and ovum, seedling is grown and observed and operation inconvenience; Because the catfish seedling climbs volt bottom and pool wall mostly, causes the difficulty of emerging from circuit.
Summary of the invention
The purpose of this utility model just is the problem and shortage that exists at existing catfish especially Yellow River catfish artificial propagation incubation equipment, thereby provides a kind of incubation equipment easy to operate, catfish artificial propagation incubator that emergence rate is high with low cost, simple in structure.
The purpose of this utility model can realize by following measure:
The utility model comprises tank, and tank is communicated in hatching basin one end by mozzle, is mounted with tap at the mozzle end, is mounted with delivery port on the hatching basin other end, and delivery port is provided with the fish-egg filter.
Mozzle is provided with filter screen in the utility model.Tap is provided with screen pack.
The utility model is owing to adopt the said equipment, and its advantage is than existing incubation equipment small investment, simple in structure, bookkeeping convenience; Quantity hatching basin according to fertilized egg is the amount doesn't matter, and each hatching basin can be put ten thousand of fertilized egg 5-10, and it is low to make quick cost, artificial controlled water velocity, and it is accurately convenient to observe, count; Be easy in time pick out the dead seedling of bad ovum, shift out seedling conveniently; Be easy to carry out at any time artificial oxygenation, effectively improve culture density per unit water body, survival rate of seedling can reach more than 95%; Not only be fit to scale centralized production in enormous quantities but also can have carried out continuous multiple batches of production, and especially the vast individuality family of breeding fish had very easily been accepted and popularized.
Description of drawings
Accompanying drawing is a front view of the present utility model;
Embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises tank 1, and tank 1 is communicated in hatching basin 4 one ends by mozzle 2, is mounted with tap 3 at mozzle 2 ends, is mounted with delivery port 5 on hatching basin 4 other ends, and delivery port 5 is provided with the fish-egg filter.Mozzle 2 is provided with filter screen.Tap 3 is provided with screen pack.
Operation principle of the present utility model is as follows:
(1) technology path: tank → mozzle → valve control → tap → hatching basin → delivery port
(2) structure and operation principle: the water source can be natural water sources such as underground water, river, reservoir or lake, answers clean, no harmful animal, pollution-free, through screen filtration suction tank; The hatching basin one end water inlet that the water siphon that will be arranged in the eminence tank by mozzle places ground from the level that flow to is (if tank is in same level height with the hatching basin or the tank level height is lower than hatching basin level height, then can increase water pump), and corresponding valve and tap (also can be only with tap or only control with valve) be installed at the mozzle of hatching basin water inlet, by valve control inflow, tap can evenly be sprayed to water in the basin, so both kept ovum in growth course, can constantly obtain sufficient fresh water supply, again can be in basin water the airborne oxygen of increase as much as possible.According to the dissolved oxygen demand, can in basin, increase the oxygenation of gas stone behind the while seedling membrane to guarantee the normal development of seedling; Water is circulated to the delivery port of the other end from the water inlet of hatching basin, fish-egg filter through being installed on delivery port and flowing out, and because the effect of fish-egg filter makes fish-egg be unlikely to be run off, dissolved oxygen all can remain on every liter more than 6 milligrams in the whole process, and the pure and fresh no harmful animal of water quality.
Claims (3)
1. catfish artificial propagation incubator, it is characterized in that: it comprises tank (1), tank (1) is communicated in hatching basin (4) one ends by mozzle (2), be mounted with tap (3) at mozzle (2) end, be mounted with delivery port (5) on hatching basin (4) other end, delivery port (5) is provided with the fish-egg filter.
