摘要:
The stern net consists of a net fabric (1) made of nylon thread with mesh (2) in the form of a diamond, an upper selection (3) of 46 m in length, consisting of a left rope (4), a right rope (5), an overlay (6) 46 pcs. and two eyelets (7), a lower fitting (8) of 44 m long, consisting of a left rope (9), a right rope (10), and two eyelets (7), two anchors (11) and two pneumatic buoys (12), connected with the anchors (11) vertically by the halves (13), as well as the eyelets located at the edges (7), used to connect the staging network to other wired networks, to form a network order. With the help of the fishing schooner, the shuttle net is removed to the fishing area and its setting is performed. From below, the structure is fixed by the anchors (11) behind the bottom, and the pneumatic buoys (12) fixed to them on the halves (13) are floated directly above the anchors (11). The mesh network on the ropes (4) (5), (9) and (10) is held in the inflated position at a distance of 50-100 m from the floating pneumatic buoys (12) and anchored to the bottom of the anchors (11). In this case, the upper selection (3) is held afloat by means of floats (6), and the lower selection (8) is in the position sunk at the bottom due to the ropes (9) and (10) fixed to the anchors (11). The presence of pneumatic buoys (12) makes it easy to visually monitor the location of the staging network, regulate the depth of its setting, and also facilitates the lifting of the staging net and the caught catch on board the fishing vessel. The use of the proposed design of the staging network allows increasing the efficiency of the staging networks and increasing productivity in the production (catch) of Pacific salmon from fishing schooners. 1 yl. (9) and (10) is held in a flooded position at a distance of 50-100 m from the floating pneumatic buoys (12) and fixed to the bottom of the anchors (11). In this case, the upper selection (3) is held afloat by means of floats (6), and the lower selection (8)
