Description
Technical field
The utility model relates to seawater fish propagation and breeding technical field, is specifically related to a kind of steck net cage buoyancy fish-egg gathering unit.
Background technology
Carrying out in seawater fish breed process, having two kinds of methods to obtain fertilized egg: the first, obtaining gamete by extruding parent population, dry method fertilization obtains fertilized egg again, though the method can obtain fertilized egg fast, but larger to fish bulk damage, lethality is high, and the fish after extruding can only breed once.The second, parent population is put into natural insemination in 200 order net cages and lay eggs, then pull parent population out, fertilized egg collected by net cage of dismantling, and the method comparatively wastes time and energy, and the fertilized egg impurity obtained is more, and also will select the parent population do not produced and put into other net cages and wait to produce.
Utility model content
For the problems referred to above, the utility model provides a kind of buoyancy fish-egg gathering unit, to solve the deficiencies in the prior art.
The technical solution of the utility model is as follows:
A kind of steck net cage buoyancy fish-egg gathering unit, comprise mesh bag, ball float, plummet and hand holding handle, the upper end of described mesh bag front opening is provided with described ball float, and the bottom of described mesh bag front opening is provided with described plummet, and described hand holding handle is positioned at described mesh bag front opening both sides.
Preferably, described mesh bag is the shape of front end and tail end all opening, and when collecting buoyancy fish-egg, described tail end opening rope is tightened.
Preferably, described mesh bag mesh is 150 ~ 200 orders.
Preferably, described hand holding handle length is 1.3 ~ 1.5 meters, and described hand holding handle lower end polishes smooth, with anti-skidding bad steck net cage.
Preferably, described mesh bag front end is oblong openings, and described rectangular length is more than or equal to the width of steck net cage, and described hand holding handle is positioned at described oblong openings dual-side, and during described mesh bag opening, mesh bag front opening height is less than or equal to 50cm.
Preferably, described mesh bag is oval shape close to mesh bag tail end place, when collecting fish-egg, facilitates fish-egg to deposit.
The beneficial effects of the utility model are: the upper end of this device mesh bag front opening is added with ball float, when collection fish-egg, mesh bag top can not sink, fish-egg is avoided to run off, the bottom of mesh bag opening is fixed with plummet, and end portion can not float, and can not affect collecting effect, and the maximum height of collecting mesh bag is 50cm, when collection fish-egg, the impurity such as the dead ovum of the parent population bottom steck net cage, sinking and ight soil can not be salvaged, thus obtain high-quality fish-egg; Collect complete, only mesh bag tail end opening rope need be untied, rinse and collect fish-egg in other containers, and use this device can collect the fish-egg of in steck net cage more than 98% back and forth through 2-3 time, it is reasonable in design, simple to operate, practical.
Accompanying drawing explanation
Fig. 1 is the utility model buoyancy fish-egg gathering unit schematic diagram.
Embodiment
For the ease of the understanding of those skilled in the art, be described further technical solutions of the utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.
A kind of steck net cage buoyancy fish-egg gathering unit, comprise mesh bag 1, ball float 2, plummet 3 and hand holding handle 4, the upper end of described mesh bag 1 front opening is provided with described ball float 2, when collection fish-egg, mesh bag 1 upper end can not sink, fish-egg is avoided to run off, the bottom of described mesh bag 1 front opening is provided with described plummet 3, and when collection fish-egg, can not float in mesh bag 1 bottom; Described hand holding handle 4 is positioned at described mesh bag 1 front opening both sides; Described mesh bag 1 is the shape of front end and tail end all opening, front opening reduces gradually to tail end, mesh bag 1 front end is oblong openings, described rectangular length is more than or equal to the width of steck net cage, mesh bag 1 tail end opening diameter is 20cm, when collecting buoyancy fish-egg, described opening rope 5 is tightened, described mesh bag 1 tail end opening also can be designed by the structure of stretching tow and realizing opening and closing, separately, described mesh bag 1 is designed to oval shape close to mesh bag 1 tail end place, when collecting fish-egg, facilitates fish-egg to be deposited in described ellipse net; Described hand holding handle 4 is positioned at described oblong openings dual-side, every root hand holding handle 4 purse seine place in the middle of the two ends, long up and down limit of mesh bag 1 front end oblong openings and oblong openings broadside is fixed by rope 5, described hand holding handle 4 length is 1.3 ~ 1.5 meters, bamboo pole or other hard light materials can be selected to make, its lower end polishes smooth, with anti-skidding bad steck net cage; During described mesh bag 1 opening, mesh bag front opening height is 50cm, when collection fish-egg, the impurity such as the dead ovum of the parent population bottom steck net cage, sinking and ight soil can not be salvaged, thus obtain high-quality fish-egg; Mesh bag 1 mesh is 150 ~ 200 orders.
During work, two people stand in the both sides of steck net cage respectively, the hand holding handle 4 respectively caught, and part mesh bag 1 being fixed with plummet 3 is submerged in water, surfaces in the upper part that mesh bag 1 is fixed with ball float 2, moves from one end of steck net cage towards the other end; After the other end of steck net cage, then collect 1-2 time back and forth, can collect the fish-egg of in steck net cage more than 98%, this device is mainly used in collecting the buoyancy fertilized egg in steck net cage.
Be more than better embodiment of the present utility model, but embodiment is not for limiting the utility model.Not departing from the spirit and scope of the utility model, any equivalence change done or retouching, belong to the protection domain of the utility model equally.Therefore the content that protection domain of the present utility model should define with the claim of the application is standard.
