Abstract

The invention relates to industrial fisheries and can be used to harvest flowing inland waters. The purpose of the invention is to improve the performance of lamprey. Non-crowns 3 of conical shape are fixed on cable 2 with bark 1. The larger base is not rare 3 serves as a bottom. The inlet 6 is mounted cantilever in the hole of the side surface of non-rare 3, and the outlet 7 is flush in the hole made in its upper part. Flexible connecting hoses 8 are connected to nozzles 6 and 7, which connect non-rare 3 with each other, and the last one with a prefabricated tank 9. Lamprey, which got into the hole through its funnel, can exit only through the outlet nozzle 7 to the next non-flow or into the tank 9. 1 Il.

Description

The invention relates to industrial fish farming and can be used to harvest flowing inland waters.

The purpose of the invention is to improve the performance of lamprey.

The drawing shows the device for. aquatic organisms.

The device contains a branched cable 2 mounted on the core 2. On the latter there are non-spreads 3 with inlet and outlet openings 4 and 5, in which the nozzles 6 and 7 are installed. Each non-mid 3 has a cone body, the larger base of which serves as the bottom. The inlet pipe 6 is located console on the side surface of the non-ordinary 3, and the outlet pipe 7 is located flush in its upper part. Nozzles 3 are interconnected by flexible hoses 8, connected to the inlet and outlet nozzles 6 and 7 of adjacent 3. The latter 3 are connected to the collecting tank 9 located on or near the shore below the water level. Each 3 has a funnel (not shown).

The device works as follows.

When the device is in operation, a fish, once inside the funnel, can exit only through the outlet fitting flush, and the console end of the inlet 6 does not allow it, moving along the walls of the outlet 3, to find a reverse exit. Thus, it enters the flexible hose 8, and from it into the next one, and so on until it is in the assembly box 9. Since

Since the fish tries to move against the current all the time, the irregularities 3 must be positioned so that the fish, moving from one minor to another, continue to move in the direction opposite to the current, without doing any sharp turns. For this, the axis of the inlet 6 must connect an obtuse angle with the direction of flow.

When using the invention, there is no need to constantly check the nered, free them from the catch, eliminating the possibility of leaving the lamprey, which improves the performance of the lamprey.

Formula of the invention

A device for catching aquatic organisms containing a cable mounted on the core, mounted on the cable is non-interconnected, interconnected, having inlet and outlet openings, characterized in that, in order to increase the performance during fishing, the non-rare are provided with branch pipes installed in their openings x, have the shape of a cone, the larger base of which serves as the bottom, the inlet of each tube is located console on its side surface, and the outlet is flush in the upper part of the deck, while the latter are connected between a flexible hose connected to the inlet and outlet pipes adjacent Nered.

Claims (1)

Claim A device for fishing aquatic organisms, containing a cable anchored to the cable, nereda attached to the cable, interconnected, having inlet and outlet openings, characterized in that, in order to increase productivity when catching lampreys, the nereda are equipped with nozzles installed in their openings, have the shape of the cone, the larger base of which serves as the bottom, the inlet pipe of each nereda is located cantilever on its lateral surface, and the output is located flush in the upper part of the nereda, while the latter are connected between fight with flexible hoses connected to the inlet and outlet nozzles of adjacent undefined.
