Description

When a floating trap is installed, partially equipped with a skeleton (Fig. 2), measles 3 are first installed, having a ring 5 {or a tension block) at the end of the root canal 4, through which the bridle 6 is attached to the wing of the nexus 7. After exposing the wing, its end is attached to the floating frame 2, which is fixed to the bottom with the help of a similar core, and with the bridle 6 through the ring 5, the entire trap is pulled and fixed. After that, the floating frame 8 and the courtyard formation 9 are mounted on the floating frame. Thus, the entire floating trap is fixed to the bottom of the reservoir with two bark 3. Each measles is equipped with a device for pulling it out, moving and turning the trap. loop 11 and (rope) buippe 12, at one end connected to the buoy, the other to the bark; The upper end of buiprep 12 is provided with a loop 11 for fastening the device on a vessel (not shown). The height of the seine is chosen depending on the object of fishing. When catching fish living in the surface layers of a reservoir, such as carp, the seine may not block the entire water column from the bottom to the surface. In the case of incomplete blocking of the reservoir, the yard formation is equipped with a bottom or a lifting road. The top of the seine boiler can be made closed. When catching aquatic organisms, the trap is made of a gas sieve. The fishing gear of the fixed seine is carried out in the usual way. Upper rebounds equip with naplavami 13, lower - with load 14.

When installing a floating trap on two bark x, the entrance to it is oriented at an acute angle of 20-80 ° to the direction of the wind current. When the trap is oriented to the wind direction and, consequently, the fish travel is less than 20 °, the elementary catching area is reduced, and when set at an angle of more than 80 °, the wing guiding role decreases, since the probability of fish leaving in the opposite direction from the net steam increases theoretically it is 50%. In both cases, fishing efficiency is reduced.

The trap is serviced as follows: Fishermen approach the seine boiler on the vessel and carry out a bulkhead, then all the fish is driven to the rear wall of the seine boiler and proceed to pouring out manually or mechanically.

When the wind changes, the trap is oriented towards the fish migrating after the feeding organisms moved by the wind current in the reservoir. For this

the fishermen on the fishing vessel approach one of the ends of the trap, loosen the bridle 6, then approach the control buoy 10, for burep 12 lift the measles 3, fix the loop 11 of the burep on the vessel and

in such a position, the whole trap is towed in a circle. When choosing the location of the trap relative to the wind flow, lower the measles to the bottom and expose the control buoy. Then using the bridle b

pull the root rope 4 and thus secure the floating trap, the design of which involves turning it around point A and around point B (Fig. 3).

When operating in the automatic mode (Fig. 4), the wing of the seine is equipped with a frame 15, and in the courtyard area a fixed frame 16 is installed, on which the sail 17, made of

special canvas or tarpaulin. In this case, in the absence of a fixing bar on the side of the underwater pipe, the trap under the action of wind and wind current will be constantly oriented by the entrance towards the migrating fish. If necessary, the trap can be equipped with a second v. when removing the sail, it can work according to the oOichnoy scheme.

Claims (3)

1. A method of fishing, involving the opening, fixing of a net trap and orientation of the entrance of the trap in the direction of the fish, characterized in that, in order to increase the efficiency of the process fishing fish migrating for feed organisms transported by a wind current in a reservoir, the trap entrance is located at an angle of 20-80 ° to the direction of the wind current, and when wind directions provide additional orientation for the entrance. 2. A method according to claim 1, characterized in that the additional orientation of the entrance of the trap is carried out using a sail. 3. A net trap for fishing, having a device for its opening and a radical attachment, characterized in that, in order to increase the efficiency of the process of fishing, the device is made in the form of a hard thrust with positive buoyancy. emm $ --- 6- H Y J   / UL / LU / 1 / yV S / S fr / f77SS77 SSSS7 // 7fSS / S / FIG g $ $ No. f QCJ 1l V vt / l X / #  / 2 # 6 3 I & a & i At e /
