Abstract

Disclosed is a fish net for the deep water trap whose net trap structure is designed into a reasonable shape, characterized in that a wing net and an entrance net and a big guiding net form a first entrance, the big guiding net and a wall net form a second entrance, a middle guiding net form a third entrance and a small guiding net and a net of a Chinese character ba shape form a door. The triangle net of the fish taking portion is upward lifted with an angle and the front end is connected with a tongue net. The structure of the utility model can generate the functions of trapping and inducing to lure the fish into the fish taking portion to densely conduct fishing. Compared with other fishing nets and methods, the fish net for the deep water trap has obvious advantages with high yield. The utility model has the advantages of low cost and low labor intensity without injuring the young fish and can provide fresh fish and can also solve the problem of fishing with high efficiency in the valley reservoirs of large size or middle size.

Description

Fishnet for deep water traps

The utility model belongs to net class Fishing tool, is a kind of instrument that mountain valley reservoir deep water is fished for multiple fish that is used for.

At present the fishing net that uses of reservoir have multiple, as gill net, subglacial draw in the net, multiple instrument and " associating fishing methods " such as trawlnet, shallow water net paper tinsel, cage are thrown the net, net cage bamboo weir.Above-mentioned multiple fishing net and " associating fishing method " are though respectively there is its strong point, and it is also more to have problems.Do not use gill net labour intensity greatly, manageability, cost height, income are not little; Use trawlnet to need consumes energy, and easy polluted water, and injury flathead, the economic juvenile fish of silver carp are more when fishing for, subglacial draws in the net only to be confined to northern area and uses winter; Shallow water net paper tinsel, cage are thrown the net, net cage bamboo weir, only suitable shallow water field operation, still impotentia, " associating fishing method " fishing kind is single to deep water, it is quite big to drop into human and material resources, labour intensity is big, and fishing all is not a kind of desirable instrument so above-mentioned multiple apparatus is for mountain valley-type reservoir deep water.

The utility model is to overcome the shortcoming that above-mentioned multiple fishing net exists, be a kind ofly be applicable to that the fishing of mountain valley-type reservoir deep water and labour intensity are little, be easy to manage, cost is low, output is high, the source of not consuming energy, can fish for multilayer, multiple fish and not injure the deep water net paper tinsel fishing net of juvenile fish.

The fishing of deep water net paper tinsel is not to catch up with to force the fish network access, but a kind of fan falls into, induces fish to network, it is mechanics along with season and reservoir level variation and fish, in time netting gear be laid in fish trips on passage or the interception of the waters of fish comparatively dense, guiding fish enter in the net, and fish concentrated on bunt fish for.

The structure of deep water net paper tinsel is made up of wing lattice, body net and bunt.The body net is made up of entrance net, fence net, big guiding net, middle wire guide, little wire guide, slubbing Kou Men, two road junction doors and three road junction doors; Bunt is made up of spacer screen, back fence net, side wall net, back cover net, side cover net, Eight characters net, the triangulation network, floppa and net door.
