Abstract
The invention discloses artificial incubation equipment for viscid fertilized eggs of fishes and belongs to the field of fish farming. The artificial incubation equipment comprises an inverted-cone shell, a cone-frustum-shaped loop, a net bag, a circular top cover, a main body support and a water inlet and outlet system. The artificial incubation equipment for the viscid fertilized eggs of the fishes has the advantages that the structure with the inverted-cone shell sleeving an inverted-cone net is adopted creatively, a gap is reserved between the inverted-cone shell and the inner inverted-cone net, wall attachment and caking can be effectively avoided with the help of bottom ascending water flow, and the inverted-cone net is capable of effectively dispersing water flow to prevent the water flow from impacting the fish eggs, so that a fish egg incubation rate can be increased; internal clearing of the incubation equipment is facilitated through the detachable bottom cone net bag; with a ringlike water pipe clearing system, the artificial incubation equipment is capable of effectively clearing mildewed embryos during incubation to greatly avoid adverse effect of excessive anthropogenic interference on egg incubation; the artificial incubation equipment is low in manufacturing cost, simple and convenient to operate and particularly suitable for large-scale factory-like breeding application in the field.
Description
Technical field
The invention belongs to fish culture field, the viscous fertilized ovum artificial incubation equipment of specifically a kind of Fish.
Technical background
Fast-developing with fish culture industry, fish fry supply also phases out into the artificial breeding stage.People are in fish
Often according to the different ecotype of fish roe in class ovum artificial incubation, using corresponding hatchery facility and method, to improve fertilization
Egg hatching rate, what guarantee fish fry was bred is smoothed out.Viscid egg is one of ecotype of fish roe, and its ovum proportion is more than
Water, egg membrane outer layer has goo, may adhere in hatching around on the object such as pasture and water, and do not sink under water, wherein fresh water
The fish ovum such as fish and marine fish Cyprinus carpio, crucian carp, Megalobrama amblycephala, Puffer fish, red fin east just belongs to such.Viscosity in nature
Fish roe dispersibles and sticks to hatching on the objects such as pasture and water, stone.But produce in Fish and breed, for improve egg hatching efficiency with
Scale, it is ensured that fish fry supply, often a large amount of ovums is distributed in hatching apparatus and together hatches, and this just inevitably causes greatly
Amount ovum adhesion, caking, produce dead ovum in a large number.Research all shows with production practices, dead ovum, injured fish roe easily infect water simultaneously
Mould, and ovum egg membrane surface of living seldom has fish moldss parasitic.Using often more than the hatching of viscous fertilized ovum such as Puffer fish at present
, so that the artificial operation task of hatching process is heavy, in hatching process, the glutinous wall of germ cell, caking phenomenon are general for the hatching apparatus of rule Fish
Time, often make embryo be subject to heavier environmental stimuli because of cleaning fish moldss ovum during hatching, cause dead ovum, hinder ovum and occur in a large number, ovum
Incubation rate is low, and artificial work intensity is big, and breeding efficiency is low, and cost remains high.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of Fish viscous fertilized ovum artificial incubation equipment, to solve class
Problem like viscid egg viscous wall, caking and removing fish moldss ovum difficulty in hatching process of Puffer fish.
The present invention is achieved through the following technical solutions：
A kind of viscous fertilized ovum artificial incubation equipment of Fish, it includes inverted cone shell, truncated cone-shaped net circle, the string bag, circle
Top cover, main body rack and culvert system；Inverted cone shell is fixed on ground by main body rack, the bottom of inverted cone shell
It is provided with an intake-discharge pipe, intake-discharge pipe has 1 water discharging valve and 1 inlet valve, is provided with one below inverted cone inside the shell
The inverted cone string bag, it is closely connected with top truncated cone-shaped net circle bottom by plug, and internal stent is passed through in truncated cone-shaped net circle bottom
It is fixed on inverted cone enclosure, the tight phase of inward flange of the circular edge above truncated cone-shaped net circle top edge and inverted cone shell
Connect, truncated cone-shaped net circle top is additionally provided with a circle backstop, circular edge is provided with outlet pipe directed downwardly, connects outside circular edge
It is connected to dash ring flat-plate, ring-type water pipe is fixed on the middle and upper part of inverted cone outer side, it is by dividing with endless tube inlet valve
Prop up water inlet pipe to connect with water inlet manifold, ring-type water pipe is also connected with the lower drain pipe with endless tube water discharging valve, ring-type water pipe is to
In conical shell, oblique cutting enters 3 radiation water pipes, and 3 radiation water pipes pass through truncated cone-shaped net circle to enter inside, and inverted cone housing
Upper end open diameter D and high H between ratio be 3:5, described water inlet manifold is connected with water source.
Further, described truncated cone-shaped net circle and backstop are stainless (steel) wire, inverted cone shell and truncated cone-shaped net circle and the string bag
Between all leave space, depending on stainless (steel) wire mesh number is all with reference to corresponding hatching ovum size, to ensure that ovum can not penetrate mesh.
Further, mesh number used by the string bag is less than mesh number used by truncated cone-shaped net circle, to promote current to rise along space.
Further, the described string bag and truncated cone-shaped net circle are all reinforced vertically with rod iron, and string bag top edge has annulus, round platform
Annulus is arranged at shape net circle bottom.
Present invention beneficial effect compared with prior art：
1. the present invention take up room little, easy and simple to handle, stable, reliable, be easy to industrial seedling rearing management.
2. the viscous fertilized ovum artificial incubation equipment of Fish of the present invention, creative employs inverted cone inside the shell cover back taper shape
The structure of net, leaves space between inverted cone shell and interior tapered net, can be prevented effectively from ovum by means of bottom ascending current attached
Wall, caking phenomenon, conic net also can effective dispersing water flow, it is to avoid current directly impact fish roe, and then improve hatch fish roe rate, with
When dismountable bottom pyramidal string bag facilitate the cleaning within incubation equipment.
2. what this equipment was creative employs ring-type water pipe cleaning system, can simply, effectively clear up sending out in hatching process
Mould embryo, largely avoid the harmful effect to egg hatching for the excessive artificial disturbance.And it is cheap for manufacturing cost, operation letter
Just, it is particularly suitable for the large-scale industrialized of this area now and breed application.
