The invention relates to fish industry and can be used in households engaged in artificial breeding and rearing of fish.

The purpose of the invention is the possibility of using the device in stagnant water bodies.

The use of a descriptive device in fish-breeding farms will make it possible to obtain fertilized eggs of fish directly under their living conditions.

FIG. 1 depicts described. 15 device, general view; in fig. 2 - the same, top view; in fig. 3 - chamber with water flow distributors.

A device for spawning fish includes pool 1 for producers, 20 mesh liner 2 placed in pool 1 with a gap between it and the bottom of the pool, longitudinal partitions 3 dividing the gap into several water lines, flaps 4 of rectangular shape, reinforced on horizontal axes x 5 can be rotated, collections 6 of fertilized caviar, cone-shaped elements 7, connecting pool 1 with the collector Nikon 6, additional chamber 8 mounted on the water supply side, devices 9 and 10 placed in it for distribution by eye water horizontally and vertically, 35

The devices 9 for distributing the water flow vertically are L-shaped, mounted on a horizontal axis 11 and equipped with an actuator 12.40.

The 10 dp adaptations of the water flow distribution are horizontally rectangular, mounted on vertical axes 13 and equipped with a 14.45 drive.

An additional chamber 8 with a trapezoidal box-shaped section has means (pipelines) 15 for connecting it to a pressurized water supply system (not shown), 5 °

 In order to improve work with manufacturers and evenly distribute them in the pool, as well as for transporting the pool 1, 55 is divided into sections with vertical mesh partitions 16. Floats 17 are attached to its non-flooded pool 1.

Device for spawning fish works as follows.

The device is installed in a non-flowing pond or pond with a weak flow of water. The water supply system by pipelines 15 is connected to an additional chamber 8.

When keeping the manufacturers, the L-shaped devices 9 are installed in such a position that the water flow enters the space above the mesh insert 2. When the fish spawns, the fertilized eggs pass through the mesh insert 2 and sink to the bottom of the pool 1 between the doors 4. There in the zone protected by the leaves from the main stream, there is swelling of eggs.

Caviar caviar is produced alternately in each conduit. In this case, the L-shaped devices 9 are installed in such a position that the flow of water from the pumping stations enters the space between the mesh liner 2 and the bottom of the basin 1, and the devices 10 direct the water stream alternately to each of the water lines. The flow of water passing along the bottom lifts the flaps 4 to a horizontal position, spurs the eggs from the bottom of basin 1, removes them from stickiness and carries the cone element 7 into collection 6 of fertilized eggs.

The presence in the device of a chamber 8 with devices 9 and 10 for distributing the flow vertically and horizontally allows the water to be directed either to the pool to ensure the living conditions of the producers, or to the spacer between the bottom of the basin and the crush for fertilized eggs, can be sent to any of the conduits formed by longitudinal partitions 3.

After spawning, producers are released into the pond.
