Description
Technical field
The present invention relates to the artificial propagation device technique field of Fish, specifically a kind of general hatching method of semi-submersible type viscous roes and device.
Background technology
In fertilized fish roe hatching process, heavy property fish roe is deposited in the bottom owing to the proportion of itself is relatively big, mutually extrudes, easily causes damage, the most mutually pile up the dissolved oxygen making fish roe cannot obtain abundance, causes incubation rate relatively low, the problems such as prelarva abnormal rate is high.Existing hatching pattern is that the viscous roes by being fertilized by Fish directly spills on the attachments such as the Folium Trachycarpi in water, mesh sheet or basin bottom, allows it naturally adhere to directly hatching.The mode of normal point is to use hatching frame or incubation tank etc., only rely on and increase the method such as the quantity of aeration stone, reduction hatching density, cannot really solve the problem that fish roe is piled up, on the other hand incubation equipment facility volume is big, and floor space is big, and water consumption is high, operation complexity, difficulty is big, and hatching efficiency is low, significantly constrains the success rate of heavy property hatch fish roe.Incubator/cabinet conventional in recent years, uses the method reducing hatch fish roe density, alleviates the problem that fish roe dissolved oxygen is not enough to a certain extent, but its volume is big, and floor space is big, and operation easier is big, expensive, it is impossible to meet the demand of common nursery.
But prior art has the disadvantage that: one is to stick to the ovum grain skewness on attachment, easily assemble adhesion and cause hypoxia death, after growing fish molds, more can cause the Large Scale Death of ovum grain；Two is that the Water space utilization rate of hatch fish roe is the highest, is easily caused water quality deterioration and the anoxia of local water body, in turn results in artificial incubation failure；Three is the incubation rate instability of fish roe, is unfavorable for the lasting large-scale production of fry and is effectively reduced production cost.
Summary of the invention
It is an object of the invention to provide a kind of incubation rate that can reasonably be distributed the incubation space of ovum grain, the hatching water body utilizing fish roe efficiently and raising and stablize fish roe; thus reduce the production cost of fry, it is ensured that fry the general hatching method of semi-submersible type viscous roes of lasting large-scale production and device.
To achieve these goals, the technical solution used in the present invention is:
A kind of general hatching method of semi-submersible type viscous roes, comprises the following steps that:
(1) fish roe prepares: be placed in container by viscous roes, and add mass percent be 0.3% sodium chloride solution and male milt, stirring 40-60 second, the male fish sperm that the fish roe of every 50-100 milliliter adds is 0.5-1 milliliter, and the amount adding 0.3% sodium chloride solution is 5-10 milliliter；
(2) fish roe attachment hatching mesh sheet: being placed in the water in pond by hatching apparatus, in semi-submersible type, hatching apparatus is that semi-submersible type refers to that a hatching apparatus part sinks to underwater, and another part is exposed on the water surface.One people spills the viscous roes of after fertilization on the water surface, and another people hauls the continuous left and right horizontal of handle of hatching apparatus and rocks couveuse, is moved made fish roe be uniformly dispersed in the hatching mesh sheet adhering to hatching apparatus by water fluctuation and hatching mesh sheet；The hatching mesh sheet of 60 × 40 centimetres every spills the viscous roes after the insemination of 50-100 milliliter；
(3) hatching the suspension of mesh sheet: the hatching mesh sheet of uniform adhesion viscous roes taken out from hatching apparatus, the most neatly hang on the lanyard in water, hatching mesh sheet interval 15-20cm, the hatching mesh sheet quantity of averagely every cube water body suspension is 3-5 sheet；
(4) hatching management: the water in pond carries out aeration aerating, keeping the water oxygen content in pond is 4-5 mg/litre, and water temperature controls at 18-25 DEG C, within every 3-5 hour, changes a water, and flow cavitation result, at 3-5 cube m/h, can hatch in 2-5 days.
The hatching apparatus that the general hatching process of semi-submersible type viscous roes uses, including handle, wooden frame, wooden underframe and hatching mesh sheet, described handle is arranged on the most penetrating wooden frame two ends, in the most penetrating potential water of wooden frame half, wooden underframe is arranged on the most penetrating wooden frame bottom, and hatching mesh sheet is placed on wooden underframe.
Described hatching mesh sheet, including mesh sheet, iron frame and hook, mesh sheet is fixed in iron frame, and hook is arranged on iron frame, and hook can rotate on iron frame.
Described mesh sheet is made up of polyethylene, and its width of mesh is 80 mesh.
The general hatching method of semi-submersible type viscous roes of the present invention and device, hatching method is simple, device arranges ingenious, practicality simple for structure, use this hatching apparatus and combine corresponding using method, the distribution consistency degree of hatching fish roe can be effectively improved, it is to avoid ovum grain stacks the hypoxia death caused, and reduce the hatching common fish molds harm to ovum grain, improve the incubation rate of fish roe further；Suspension type ferrum limit being designed with of mesh sheet of hatching is beneficial to Water space utilization rate is greatly improved, it is simple to carries out extensive fry hatching and produces；This hatching apparatus manufacture method is simple, raw material is easily looked for, and holistic cost is relatively low.This hatching apparatus is based primarily upon breeding biology of fish principle and designs, self-characteristic and environment of hatching condition with particular reference to viscous roes, as after Fish in vitro fertilization, ovum grain is freely scattered with current in water and adheres on object matsurface, thus design produce semi-submersible type couveuse frame and hangable ferrum limit hatching mesh sheet, by artificial insemination splash fish roe and manually rock couveuse manufacture current make fish roe be uniformly distributed in mesh sheet.By applying this hatching apparatus, the most successfully hatching the seed of the multiple viscid egg grain Fish such as plan, Su Shi circle abdomen (fish awns) in Cyprinus carpio, Carassius auratus, Pelteobagrus fulvidraco, oblique jaw silver xenocypris, Usu, effect is notable.Wherein, the ovum grain of Su Shi circle abdomen (fish awns) is carried out hatching test monitoring; find that incubation rate improves at least 20% than traditional hatching method; reach more than 80%; pond hatching density is improved to 60,000 tails/m by 10,000 original tails/m; year hatches more than this kind fry 20,000,000 tail, it is achieved that the large-scale production of the famous and precious kind of Fish.
