Abstract
The invention discloses a transplanting and dispensing net for fertilized eggs of large icefish. The transplanting and dispensing net for fertilized eggs of large icefish comprises a cage and a support frame. The cage is composed of a frame and netting pieces. The top of the cage is open. The netting pieces are fixed to other sides of the cage. The support frame with adjustable height is disposed below the bottom netting piece. A plurality of floats equal in length are further connected to the frame of the cage. A loop is reserved at the edge of the bottom netting piece. The invention further discloses an inspection disk comprising an inspection disk frame and a netting piece fixed on the same. Floats are connected to the inspection disk frame. The transplanting and dispensing net for fertilized eggs of large icefish has the advantages that no piling is needed in laying the transplanting and dispensing net, the transplanting and dispensing net can be disposed underwater directly, and accordingly cost is reduced; optional adjustment of height of support legs can reduce probability of accumulation of the fertilized eggs and increase hatching rate and transplanting success rate of the fertilized eggs of large icefish; and by the aid of the added inspection disk, regular inspection on growth of the fertilized eggs is more convenient and quicker.
Description
Technical field
The present invention relates to a kind of big silverfish transplantation of fertilized egg and throw in netting gear.
Background technology
Big silverfish
(Protosalanx hyalocranius Abbott) be the bigger annual high-quality fish of individuality in the Salangidae, delicious meat, stingless, protein content is high, has very high fishery and is worth; Because of its fast growth, fertility is strong simultaneously, is the good kind that lake, reservoir are transplanted propagation.
The trasplanting method of domestic big silverfish mainly contains parent population grafting, young juvenile fish grafting and transplantation of fertilized egg method at present.And fertilized egg is stronger to the adaptive capacity of environmental change; Have very strong vitality during the embryonic development, and the method for transplanting fertilized egg is simple, early development stage plasticity is big; The propagation of the disease that can keep off infection again, thus generally all with fertilized egg as graft materials.It is simple to transplant the fertilized egg method, and expense is few, and transportation survival rate is high.The fertilized egg of transplanting artificial insemination is generally adopted in the transplanting of therefore big silverfish.When big silverfish transplantation of fertilized egg, can the input of fertilized egg be to transplant one of key factor that successful.The mode that direct substrate is thrown in and utilized net cage to hang is mainly adopted in the input of fertilized egg at present, and directly substrate is thrown in the restriction that receives the substrate condition, the increase of bed mud thickness, fertilized egg hatching rate and descending, and then the influence success rate of transplanting; And hanging in default of the netting gear of special use of net cage causes the increase of transplanting cost, needs the whole water outlet of casing when making regular check on the fertilized egg hatching progress simultaneously, causes the inconvenience of inspection.
Summary of the invention
The purpose of this invention is to provide the special-purpose netting gear of throwing in of a kind of big silverfish transplantation of fertilized egg; Solve at present and throw in fertilized egg accumulation because of the conventional net cage of big silverfish fertilized egg; Substrate input mode receives drawbacks such as water body substrate situation restriction, with the incubation rate that improves big silverfish transplantation of fertilized egg and the success rate of transplanting.
For realizing the foregoing invention purpose, adopt following technical scheme:
A kind of big silverfish transplantation of fertilized egg is thrown in netting gear, comprises net cage and bracing frame, and net cage is made up of framework and etting, and the top mouth is open, and other faces are fixed with etting, and bracing frame is arranged at spacer screen below, adjustable-height.Also be connected with a plurality of isometric ball floats on the net cage frame, the spacer screen edge leaves the collar.The shape of net cage can be cuboid, the square bodily form, cylinder etc., and the setting of the number of bracing frame is enough to support net cage can steadily place, and can adopt integrative-structure with vertical framework in the net cage frame.
The present invention also provides a kind of inspection panel, is used to make regular check on the fertilized egg hatching progress and need net cage integral body not be shifted out the water surface.Inspection panel comprises the inspection panel framework and is fixed in the etting on the framework, is connected with ball float on the inspection panel framework.
The frame part of net cage and inspection panel is processed with metal material, and etting adopts polythene material to process, and ball float adopts polypropylene material to process.
Advantage of the present invention is: netting gear is laid Shi Buxu piling, can directly throw in water bottom, provides cost savings; Any adjusting of feet height can reduce the generation that packing phenomenon takes place fertilized egg, improves big silverfish fertilized egg hatching rate and transplanting succeed rate; Increased inspection panel simultaneously, it is more convenient to make regular check on the development of fertilized ova situation.
Description of drawings
Fig. 1 is the structural representation of netting gear of the present invention, and wherein 1 is net cage, and 2 is spacer screen, and 3 is bracing frame, and 4 is the collar, and 5 is ball float;
Fig. 2 is the structural representation of inspection panel of the present invention.
Embodiment
Below in conjunction with specific embodiment the present invention is done further elaboration.
A kind of big silverfish transplantation of fertilized egg is thrown in netting gear, comprises net cage 1 and bracing frame 3, and net cage 1 is made up of framework and etting, is shaped as cuboid, and the top mouth is open, area 4-5m
2, the high 0.3-0.5m of casing, concrete height is decided to transplant the water body depth of water; Spacer screen 2 meshes are the 50-60 order, and net cage limit net mesh is the 30-40 order; Feet 3 bottoms under the spacer screen 2 are the square of 3cm*3cm, and feet 3 adopts telescopic can the adjusting highly, when net cage 1 is laid in water body; Gradient according to water bottom; The height of adjustment feet 3 is laid back spacer screen 2 and is kept horizontal to guarantee casing, avoids the accumulation of fertilized egg; Spacer screen 1 is advisable to be higher than water bottom 5-10cm apart from the distance of feet 3 bottoms; It is smooth and tight that the laying of spacer screen 1 will keep, and avoids fertilized egg to throw in the back and become flexible, and causes accumulation.Be connected with isometric ball float 5 on the framework of net cage 1, so that seek net cage 1 placement location and levelness.It is firm that the fixedly employing polyethylene rope of spacer screen 1 etting will net the sheet socket by order, and make the collar 4 at four jiaos of ropes of reserving certain-length, is used for the set net cage or hangs weight.The guiding principle rope passes part and tightens, pricks dead by order with formal wire again.
Inspection panel: be made up of framework and etting, framework is circular, area 0.01 m
2, the etting mesh is the 50-60 order, connects cord on the framework, the cord other end connects ball float.During use inspection panel is placed on the bottom wire side of net cage 1, it is good that adjusting cord length does not drive inspection panel with the floating naturally water surface of ball float.When making regular check on the development of fertilized ova situation, only need carry ball float and inspection panel is left the water get final product, not need the integral body of casing to move.The number of inspection panel can be placed one or more as required.
