The utility model relates to the field of industrial fishing and can be used as a tool for the extraction (catch) of Pacific salmon.

Known fixed single-walled network containing a rectangular mesh cloth, planted on the upper and lower seams and on the side veins, while the mesh cloth is made of a deltoid cell, and the sum of the lengths of two short sides is equal to the long side of the deltoid, when landing short sides form vertical posts and long ones form a sag (see Patent for utility model of the Russian Federation No. 145912, IPC АКК 69/00, publication 06/24/2014).

Known fixed net, including a guide wing, a courtyard with openings, a lifting road and a cage, equipped with distributed buoyancy over the top selection in the form of weld deposits (see Utility Model Patent of the Russian Federation No. 93216, IPC АКК 69/00, publication 04/27/2010).

A net is known that contains a net part, an upper selection equipped with overlay, the lower one with sinkers and a tie cable passed through the rings (see Utility Model Patent of the Russian Federation No. 86408, IPC А01К 73/00, publication September 10, 2009).

The closest analogue to the claimed utility model is a net fence to protect the water area, comprising a net fabric, upper and lower rebounds, surfacing, sinkers, braces and anchors, while the mesh fabric is made of cross-linked, alternating small-mesh and large-mesh mesh isosceles triangles the same size (see Patent for utility model of the Russian Federation No. 129361, IPC АКК 74/00, ЕВВ 3/04, ЕВВ 3/12, publication 06/27/2013), adopted as a prototype.

A disadvantage of the known models and prototype is the lack of reliable protection against wind waves and currents in fishing areas due to incomplete immersion of the upper selection, the reduction of the objec- tive and confusing capabilities of the net web due to the skew of the meshes, the inability of vessels to pass over the place of installation of the net web, the difficulty of raising the net and catch aboard a fishing vessel.

The problem, which is aimed by the claimed utility model, is to eliminate the disadvantages inherent in known analogues and prototype.

The technical result achieved by the implementation of the claimed utility model consists in expanding the operational capabilities, as well as the scope of the fixed network, by increasing the efficiency of the fixed network and increasing productivity in the extraction (catch) of Pacific salmon from fishing schooners.

The specified technical result is achieved by the fact that in a fixed network, which includes a tight net, upper and lower seams, overhangs, braces and anchors, according to a utility model, a nylon net web with a thickness of at least 0.48 mm with a mesh pitch of 65-67, 5 mm, while the net cloth has 705-730 cells in length and 69-73 cells in height, the upper and lower rebounds consist of left and right ropes and grommets, and the upper selection is equipped with surfacings in an amount of at least 46 pcs., While the fixed network is anchored in the area of extraction (catch) with help Strongly pneumatic buoys connected with anchors vertically halyards and located on the edges of eyelets used for entangling network connectivity with other fixed nets, for the formation of net-order.

In the fixed network, the length of the upper rebound is 46 m, and the lower rebound is 44 m.

The utility model is illustrated in the drawing:
