Description

Mouth mantis shrimp catching net

Technical field

The utility model relates to a kind of aquatic products and fishes for instrument, particularly a kind of mouthful of mantis shrimp catching net.

Background technology

When carrying out the cultivation of mouthful mantis shrimp, need regularly mouth mantis shrimp to be pulled out from Cultivation container, to measure the parameters such as body length, body weight, what generally use is all the hand dredger being comprised of 20 ~ 40 object bolting silk nets, plastic frame of buying in Shui nationality market.Because the pedes sucunmus specialization of mouth mantis shrimp becomes the powerful foot of plunderring, therefore the dactylus of its front end has 6 thorn-like projections, and while fishing for mouthful mantis shrimp with common hand dredger, its pedes sucunmus often can be hooked on bolting silk and cannot depart from the net, if go to win with hand, very easily by the uropodium of mouth mantis shrimp, stabbed; If firmly excessive while winning mouthful mantis shrimp, also bolting silk net can be torn simultaneously.Can say, this conventional hand dredger has reduced catching rate because often there is a mouthful mantis shrimp hook, therefore need to make now a kind of novel catching net that can avoid above-mentioned drawback.

Summary of the invention

The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, can prevent in the process of fishing for a mouthful catching net for mantis shrimp hook.

Technical solution of the present utility model is: a kind of mouthful of mantis shrimp catching net, comprise handle and screen frame 1, it is characterized in that: in screen frame 1, be provided with 300 object bolting silk nets 2, at the middle part of bolting silk net 2, be evenly equipped with a plurality of penetrating annular hard device eyes 3, the diameter of annular hard device eye 3 is 3-4mm, and the density of annular hard device eye 3 is 5-6/dm ².

Compared with the existing technology, tool has the following advantages the utility model:

The mouth mantis shrimp catching net of this kind of version, it is simple in structure, designs ingenious.Traditional net of fishing for is when carrying out the fishing for of mouthful mantis shrimp, and because its mesh aperture is larger, the pedes sucunmus of mouthful mantis shrimp is easily hooked on the net, affects catching rate, mouth mantis shrimp is also needed expend extra work from fishing for to take off on the net simultaneously; For above-mentioned variety of problems, the utility model is designed a kind of catching net of special construction, less and the smooth texture in its main body bolting silk net meshe aperture, hook that can anti-seam mantis shrimp, so just can improve catching rate, avoid unnecessary work, simultaneously also reduced the danger that operating personnel are stabbed by it when netting gear is won mouthful mantis shrimp, therefore and by being provided with thereon a plurality of annular hard device eyes for draining, when carrying out the fishing for of mouthful mantis shrimp, also breeding water body can not taken out of in the lump; The manufacture craft of this catching net is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of mouthful of mantis shrimp catching net, comprise handle and screen frame 1, be provided with bolting silk net 2 in screen frame 1, the width of mesh of this bolting silk net 2 is 300 orders, at the middle part of bolting silk net 2, be evenly distributed with a plurality of penetrating annular hard device eyes 3, the density of these annular hard device eyes 3 is 5-6/dm ², and the diameter of all annular hard device eyes 3 is 3-4mm.

While utilizing a mouth mantis shrimp catching net of the utility model embodiment to carry out fishing for of mouthful mantis shrimp, due to the aperture of its mesh less (only having 300 orders) and smooth texture, therefore can avoid the pedes sucunmus of mouthful mantis shrimp to be hooked on bolting silk online, although less for anti-seam mantis shrimp hook by mesh aperture design, bolting silk net 2 easily stops up, but because the middle part at bolting silk net 2 arranges a plurality of annular hard device eyes 3, water body can flow out by these annular hard device eyes 3, can when fishing for, water body not brought up in the lump.
