Abstract

The invention relates to fish farming, can be used in standing water conditions (in lakes) for spawning of whitefish, in particular, pellets, and is aimed at simplifying the design, improving the conditions of caviar and thereby reducing the cost. In the device, a collection of 2 fertilized roe is made in the shape of a pyramid, turned upside down. In the collection there are installed longitudinal partitions 5, which with transverse partitions 6 form channels 7 for the passage of caviar. The caviar drive 3 is equipped with a removable mesh cassette 8 and a valve 9 for draining water, and the means for connecting the collector 2 and the accumulator 3 is a flexible hose 4, one end of which is connected to the top of the pyramid and the other to the accumulator 3, which is equipped with a check valve 10. 3 ill.

The invention relates to fish farming and can be used in standing water conditions (in lakes) for spawning of whitefish, in particular, singing.

The purpose of the invention is to simplify the design and improve the conditions for the content of caviar, thereby reducing its cost.

The proposed device allows to expand the possibilities of its application in the conditions of the standing waters of lakes, in the absence of water flow, at low temperatures, when the water bodies are covered with solid ice, and also allows to protect the eggs from mechanical damage.

FIG. 1 shows a device, general 5 view; in fig. 2 - caviar drive; on ; FIG. 3 - check valve in the accumulator. : The device for spawning fish consists of I netting tank 1, located below I collection 2 of accumulator 3, and means I for connecting accumulator 3 with collection 2, 20: made in the form of a flexible hose 4.: Collection 2 is made in the shape of a pyramid,; facing downwards. At the top of the pyramid (collection 2), there are 5 longitudinal and 6 transverse partitions, which form 25; 7 channels for caviar passage.

The drive 3 is equipped with a removable mesh cassette 8 and a valve 9. The drive 3 is sealed with an open top. The flexible hose 4 is connected to one collector with an end to collector 2 (to the top of the pyramid), -JQ and the other to drive 3, which is equipped with a check valve 10.

; The device for spawning fish works: as follows.

After the accumulator 3 is filled with water with caviar (pressure equations), the valve 10 is automatically closed, the pump 3 is removed from the water, the water from the accumulator 3 is discharged through valve 9. The caviar cassette is removed from accumulator 3. If necessary, pumping caviar from collection 2 is repeated several times.

In the proposed device, the simplification of the structure is achieved due to the rejection of the pivotal partitions and the water supply system for washing away the swollen caviar, since the water flow is generated automatically when the accumulator 3 is buried. In addition, the device does not require additional operation costs (water supply, electricity supply for water supply), which reduces the cost of caviar.

Claims (3)

Invention Formula A device for spawning fish, consisting of a netting container for keeping and spawning of producers, located under it a collection of fertilized eggs. In the container 1, the producers are deposited - mounted in a collection of transverse I and kept there until maturation of the genital: products and spawning. During spawning, you-: the methane and fertilized eggs roam through the mesh bottom of the tank 1 and sink to the walls of the collection 2. The first time after spawning the fish, the roe sang is still non-gluing and this allows it to freely roll down the inclined planes formed by the sides of the pyramid into its lower part (top) where it falls into the channels 7. To the roe that is in the channels 7 , has a constant access to water, as a result of passing through the walls, pyram.a.y, also made of mesh material, and partitions 5 and 6. In channels 7, the eggs swell and the first division of the zygote occurs, after which the eggs are collected in the accumulator 3. baffles, a storage device for swollen caviar and a means for connecting the storage device with a collection, characterized in that, in order to simplify the design, improve the conditions of the content of caviar and thereby reduce 40 of its cost, the collection of fertilized caviar is made in the shape of a pyramid, turned upside down, additional longitudinal partitions are installed in the collection, which form transverse caviar channels with channels for caviar passage, the caviar drive is equipped with a mesh cassette, a check valve and a valve for water discharge, and The means for connecting the collector to the accumulator is a flexible hose, one end of which is connected to the top of the pyramid. 0 5 0 5 Jq 2 calves lies in The process of collecting is as follows. The accumulator 3 without water at the closed position of the check valve 10 and the valve 9 is lowered into the water (deepened) so that its upper edge is slightly higher than the water level in the reservoir, while the accumulator 3 is filled with water by means of communicating vessels through the hose 4. The current of water generated in channels 7 then draws caviar and carries it to accumulator 3, while the check valve 10 opens under the pressure of water. After the accumulator 3 is filled with water with caviar (pressure equations), the valve 10 is automatically closed, the pump 3 is removed from the water, the water from the accumulator 3 is discharged through valve 9. The caviar cassette is removed from the hopper 3. If necessary, pumping eggs from collection 2 is repeated several times. In the proposed device, the simplification of the structure is achieved due to the rejection of the pivotal partitions and the water supply system for washing away the swollen caviar, since the water flow is generated automatically when the accumulator 3 is buried. In addition, the device does not require additional operation costs (water supply, electricity supply for water supply), which reduces the cost of caviar.
