(54) FISHING HARNESS (57) FIELD OF THE INVENTION The invention relates to the fishing industry. The purpose of the invention is to provide ease of use. The side inserts of the mouth part are provided with flexible plates mounted on a frame of longitudinal and transverse flexible elements to form a visor. The hard cable tightens the extreme points-t of the front edges of the inserts during pelagic trawling 4 or more.

FIELD OF THE INVENTION The invention relates to fisheries and can be used for trawling

The purpose of the invention is the convenience of using

Figure 1 shows schematically the proposed trawl for fishing with a reduced perimeter of the mouth during fishing of pelagic objects; Fig 2 is the same, with increased horizontal opening during the catch of bottom objects; FIG. 3 shows a side insert with a hydrodynamic device and tension cable; on figo4 - equip the gangway with a load carrier and

The trawl contains a net bag I, an orifice part, I have (wk1 side wedge-shaped net inserts 2, the wing of the Ustye part is planted on the upper, lower and lateral rebounds 4-6o) buckets 7 a Each wedge shaped insert 2

edged with rope 8, which is included in the wellhead part, is provided with rings 9 with a tension cable threaded into them 10. The front part of the insert 2 is connected to the main beam with a quick-release seam (it uses a hydrodynamic device made in the form of tarpaulin 11 in the form of plates 1 1 mounted on flexible frame 12 of longitudinal and transverse connections On the longitudinal cable ties of frame 12 are fixed rings 13 for passing the tie-down cable lOj The rope 8 is equipped with benzyl fastenings 14c, 1 Cyc H is fixed on the frame 12 with formation of a visor Rear end of the tie the dew 10 is rigidly fixed on the rope of the tail section of the frame 12, and the front end is threaded through the ring 15 installed at the junction of the lower wing 3’s assembly 16 with the lower selection 5, zigzagly passed through the rings opposite the a1-1x cross-links of the frame 12, successively through front cross rings

The invention allows both pelagic and accumulated data to be fished with a single trawl.
