Background technology
China is maximum in the world aquaculture country, no matter be mariculture or freshwater aquiculture, all has very important status.In recent years, the inland aquaculture water surface is more than 566 ten thousand hectares, and the mariculture water surface is more than 132 ten thousand hectares.Because culture fishery overall technology and managerial skills are not high, it is insufficient comparatively general to cause culture resources to utilize, and embodies a concentrated reflection of the yielding poorly of extensive style cultivation, benefit is low and the consumption of intensive cultivation height, per unit area yield are low.As: because production technology is backward and negligence of management, thereby cause per unit area yield and economic benefit not high.
The fish seed rearing is an important step of aquaculture.Wherein, the fry of cultivating being fished for, packs, transports is the important step of fish culture.Existing method of fishing for fry is more loaded down with trivial details, and easily to the fry injury, affects its survival rate.Therefore, be necessary to invent a kind of device of effectively fishing for fry, adopt this device can effectively fish for fry in the pond, and simple to operate, reduce mechanically actuated to the damage of fry, thereby improve fry survival rate, increase culture benefit.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of device of effectively fishing for fry, can effectively fish for the fry that cultivates in the pond, reduces mechanical damage, improves survival rate and culture benefit.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of device of effectively fishing for fry is provided, comprise rope, net sheet and net cage, it is cursory to be fixed with on the described rope, described rope is connected to one side of net sheet, described net sheet is rectangular, long limit links to each other with rope, the long limit of another of described net sheet connects plummet, described plummet is distributed on another long limit of net sheet, described net sheet center connects net with a connecting hole, described connection net is tapered, the large end of tubulose is connected to the connecting hole of net sheet center, small end connects net cage, described net cage is cube structure, be opened on the top, the frame place is fixed with that several are cursory up, has the small end that through hole connects net on the described net cage sidewall.
Described rope adopts nylon material to make diameter 1cm.
On the described rope every at a distance of 1m fix 1 cursory.
Described net sheet and/or connection net are polythene material.
The about 1.8m of described net sheet height, length can be decided according to the size in pond.
Described plummet is fixed on the lower end of net sheet, and every 1m apart fixes 1.
Its length of described net cage is 30 to 250 centimetres.
Its length of described net cage is 150 centimetres.
Described net cage its top each frame fix 2 cursory.
Described connection net screen frequency is 10 order/inches, and net sheet screen frequency is 5 order/inches, and net cage surface screen frequency is 10 order/inches.
Beneficial effect
The utility model can be regulated according to the big or small needs in pond the length of rope and net sheet, adopts this device to fish for fry, can effectively fish for all individualities, has reduced damage, raising survival rate and culture benefit to fry, and simple to operate, easy grasp.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, a kind of device of effectively fishing for fry, comprise rope 1, net sheet 2 and net cage 4, be fixed with cursory 5 on the described rope 1, described rope 1 is connected to one side of net sheet 2, described net sheet 2 is rectangular, long limit links to each other with rope 1, the long limit of another of described net sheet 2 connects plummet 6, described plummet 6 is distributed on another long limit of net sheet 2, described net sheet 2 centers connect net 3 with a connecting hole, described connection net 3 is tapered, the large end of tubulose is connected to the connecting hole of net sheet 2 centers, small end connects net cage 4, and described net cage 4 is cube structure, is opened on the top, the frame place is fixed with that several are cursory 5 up, has the small end that through hole connects net 3 on described net cage 4 sidewalls.
