Abstract

The utility model relates to a net type screening sheet for fishery, comprising a netting, an upper wearing gear, a lower wearing gear, a float, and a sinker. The utility model is characterized in that the netting is connected with a sieve mesh; a hauling with one specification can change the sieve meshes with various specifications to achieve the purpose of catching various fishes. The utility model has the advantages of fishing net saving, investment reducing, orderly specification, time saving, labor saving, simple structure, convenient installation, high separating speed, little possibility of damaging fish, low cost and high durability, fishes filtrated in an adult fish pond, and a fish net cage with good drainability and against enemies combining.

Description

The fishery net type screening sheet

The utility model relates to a kind of fishery net type screening sheet that has been used for catching and screening fry, fingerling, adult fish or cultured fishes.

Usually, haul seine is used in big waters or pond fishing operation more, the fish that catches disembarkation again with hand or portable sieve mesh with the fish sifting sort.When using the haul seine fishing, often have during small fish is caught to network, be reentered into after the screening in the water, so repeatedly draw in the net, can influence the growth of little fingerling, simultaneously, haul seine also usually tangles the fish cheek, causes the lethality of fish to increase.And, this fishing operation, the fisherman generally will dispose the haul seine of plurality of specifications mesh, to be suitable for the fish that catch different size, must strengthen investment like this.

At present, becoming in the fish pond to screen marketable fish, also many use basket type sieve meshes are manually dragged for choosing, and this handwork work efficiency is low, and labour intensity is big, and inapplicable screening large size fingerling.

The net cage that existing cultured fishes are used adopts the metal material braiding more or adopts polyethylene or synthetic line making net wall, makes net cage again.Metal wire casing is made complicated, moves and rise all inconveniences of fish.Line matter net cage matter is soft, easily makes the muroid harmful animal and destroys, and also easily causes growing nonparasitically upon another plant of attachments such as bryozoan, spiral shell, tire shellfish, and drainability is poor.

The purpose of this utility model is to address the above problem and provides a kind of simple in structure, save investment, simple installation, separation velocity is fast, be difficult for hindering fish,, reached and caught the plurality of specifications fish with a kind of sieve sheet that draws in the net to change different size of specification, and it is good to form water filtering performance, and anti-harmful animal is cultured the fishery net type screening sheet of fish box.

The purpose of this utility model is achieved in that a kind of fishery net type screening sheet, comprises etting, headline, infraclass, float, sinker, it is characterized in that being connected with on the etting sieve mesh.Sieve mesh is made of vertical pole (pipe), quarter butt (pipe), transverse tube (bar) company of wearing the sieve mesh line.

The utlity model has following advantage:

1. can screen fry, the above large size fingerling of 50 gram/tails and adult fish, separation velocity is fast, is difficult for hindering fish.

2. a specification draws in the net to change the sieve mesh of different size, rises and catches the fish of plurality of specifications, can save fishing net, reduces investment.

3. go up netting and be difficult for hanging the cheek, reduce the lethality of fish.

4. rise when catching adult fish, can increase the growth of drawing in the net number of times and not influencing the small dimension fingerling.

5. play the fishing class, neat specification is easy to classification, improves work efficiency.

6. can in becoming the fish pond, screen fingerling, time saving and energy saving.

7. can form fish culture cage, tank wall matter is hard, straight and upright, wear-resisting, does not subject to the harmful animal invasion and attack and destroys.

8. sieve mesh is smooth, reduces growing of attachment, and water filtering performance is good.

9. easy to use, it is easy, collapsible, crooked to change sieve mesh.

Fig. 4 is the utility model embodiment 2 structural representations.

Provide following preferred embodiment below in conjunction with accompanying drawing:

Embodiment 1

Consult Fig. 1, shown in Figure 2, the fishery net type screening sheet mainly is made of etting 1, sieve mesh 2, headline 3, float 4, sinker 7, infraclass 8 and various line.Consult shown in Figure 3, the utility model can be connected on the haul seine 11, it draws in the net 11 can adopt closeer mesh, its headline 3 is provided with float 4, infraclass 8 is arranged with sinker 7, drawing in the net to connect the etting 1 that has sieve mesh 2 by line 6 on 11, can be according to drawing in the net 11 length, width is provided with of the present utility model number and shape, its shape can be the prolate type, can be connected and draw in the net 11 middle part, sieve mesh 2 is by several vertical poles (pipe) 12, quarter butt (pipe) 13, transverse tube (bar) 14 constitutes, link together with sieve mesh line 16, lock slabbings with tapered end 15, and be connected with etting 1, by headline line 10 and infraclass line 9 and last by etting line 5,

infraclass

3,8 connect.Be suitable for the fishing operation of big waters and in the adult fish pond, screen fingerling.

Embodiment 2

Consult shown in Figure 4ly, the utility model can adopt line 6, headline line 10 and infraclass line 9 will have the etting 1 of sieve mesh 2 or not have the independent sieve mesh 2 of etting to connect to form net cage, is used to culture various fish.Fish culture cage can be made into shapes such as rectangle, positive square, round, ellipse, and can be made into the end has lid to be sunken to the uncovered net cage of formula and the formula that emerges under water.The end and lid can adopt the utility model net type screening sheet to make, and also can adopt etting to make.All the other structures and connected mode are with embodiment 1.

The length size in length size of the present utility model and order hole is not restricted to the described embodiments, can be according to operation place difference, draw in the net the different different making tandem products of size, catch, screen, culture fingerling, the adult fish of different size to have adapted to the fish culture box size.

Claims

1. a fishery net type screening sheet comprises etting, headline, infraclass, float, sinker, it is characterized in that being connected with on the etting (1) sieve mesh (2).
