Abstract
The utility mode relates to a fish zygote collecting net which comprises a central bracket, rectangular frames and bolting silk net bags, wherein the rectangular frames are fixed on both sides of the central bracket respectively; the bolting silk net bags are fixed in the two rectangular frames respectively; and handles are arranged on the two rectangular frames respectively. The fish zygote collecting net has a simple structure, is convenient to operate and for collecting the zygotes in the circular cement pit and is favorable for reducing the damage of zygotes.
Description
Technical field
The fertilized egg that the utility model relates to during the artificial breeding is collected netting gear, particularly relates to a kind of fish oosperm and collects netting gear.
Background technology
Artificial breeding is a whole important component part of propagating artificially in the industry, and the height of hatchability of fertile eggs and prelarva survival rate is directly connected to the economic benefit of artificial breeding industry between nursery stage.As everyone knows, the factor that influences the fish oosperm incubation rate has a lot, as water quality, temperature, illumination or the like.Yet during artificial breeding, the collection of fertilized egg operates in to a certain extent in the parent population spawning pond also can influence the fertilized egg hatching rate.Because the fertilized egg egg membrane very easily breaks, therefore improperly or multiple collection operation can cause a large amount of fertilized egg egg membranes to break or damage, thereby cause the incubation rate reduction.Therefore, how collecting the damage that farthest reduces in the operating process fish oosperm in fertilized egg, is a very important research contents.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of fish oosperm and collects netting gear, is convenient to the collection of fertilized egg in the circular cement pit, helps reducing the damage to fertilized egg.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of fish oosperm to collect netting gear, comprise center bearing bracket, rectangle frame and bolting silk mesh bag, described center bearing bracket both sides are fixed with a described rectangle frame respectively; All be fixed with a bolting silk mesh bag on described two rectangle frames; Described rectangle frame is provided with handle.
One side of described rectangle frame is fixed on described center bearing bracket both sides by the stainless steel rotating shaft.
Described center bearing bracket lower end grows described rectangle frame base 20cm.
Described center bearing bracket adopts stainless steel to make.
Described rectangle frame adopts stainless steel to make.
Described bolting silk mesh bag adopts 100 mesh sieve tulle bags.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model is simple in structure, and is easy to operate, is convenient to the collection of fertilized egg in the circular cement pit, helps reducing the damage to fertilized egg.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.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 institute restricted portion equally.
Embodiment of the present utility model relates to a kind of fish oosperm and collects netting gear, as shown in Figure 1, comprises center bearing bracket 1, rectangle frame 2 and bolting silk mesh bag 3.Center bearing bracket 1 both sides are fixed with a rectangle frame 2 respectively, and wherein, center bearing bracket 1 and rectangle frame 2 all adopt stainless steel to make, and rectangle frame 2 is to be fixed on center bearing bracket 1 both sides by stainless steel rotating shaft 4, and the lower end of center bearing bracket 1 grows rectangle frame 2 base 20cm.All be fixed with a bolting silk mesh bag 3 on two rectangle frames 2, wherein bolting silk mesh bag 3 can adopt 100 mesh sieve tulle bags, and rectangle frame 2 with on the another side that center bearing bracket 1 links to each other also is not provided with handle 5.
When the utility model uses two stainless steel rectangular frames are put into circular cement pit, the stainless steel center bearing bracket is fixed on the central sewage draining exit place at the bottom of the circular cement pit pond, whole device is erected in the circular cement pit, two hand-held respectively handles that are arranged on the stainless steel rectangular frame of people go in the same direction, around one week of cement pit trawlnet.Collect when finishing, earlier 2 stainless steel rectangular frames are slowly carried away the water surface, then fertilized egg the collecting in the 100 mesh sieve tulle bags got final product.Be not difficult to find that the utility model is simple in structure, and is easy to operate, is convenient to the collection of fertilized egg in the circular cement pit, helps reducing the damage to fertilized egg.
