It is designed to protect deposited eggs of 15 eggs, larvae of farmed fish from adverse external anthropogenic influences, as well as to keep fish when using the spawning structure as a cage.

The fastening cable 4 is intended for the directional movement of the sheath 3 under the telescopic frames lowered into the water and the subsequent fixing of the free edges of the sheath 3 on the walls of the drums 5 and 6 or on the bollards 14 mounted on the metal flooring 2 of the pontoon 1.

Drums 5 and 6 are. hollow cylinders with a horizontal axis of rotation, mounted parallel to one another at the sides of the pontoon 1 and:. designed to secure the free edges of the shell, to store and move the shell 3 under the lowered telescopic frames; Drums 5 and 6 are mounted on metal floor 2 and are rotated by means of a winch 7,

The winch 7 serves as a drive for rotating the drums 5 and 6 during the insertion and movement of the shell material 3 under the lowered telescopic frames.

Telescopic frames are designed to fasten the sheath material 3, which forms a closed water space of an artificial breeding ground under the pontoon 1, and protect it from deformation and damage to the netting 15.

The telescopic frame includes a sliding system of cylindrical nozzles 8 of equal length with a rod 9 at the end and a fastener 10, a locking screw 12 and spring shock absorbers 13. Dilindrides nozzles 8 fit into each other by fixing the working position with collet clamps and are intended for measuring the length of the telescopic frame depending on the height of the moved artificial breeding ground and the depth of the reservoir.

The rod 9 is a composite part. The telescopic frame, has a curvilinear shape, is rigidly connected to the internal cylindrical socket 8 at the base and, at the same time, freely rotates around its own vertical axis. This allows it to be oriented with a concave part both inside the pontoon t, for example, when the device is moved in the non-working position with raised telescopic frames, and in the working position with the telescopic frames lowered.

The latch 10 is mounted on the upper end portion of the curved rod 9 and has the form of an open groove (groove) for fastening the cable 4, which serves as a guide for moving the cover 3

The rotary mechanism 11 of the telescopic frame consists of a horizontal support bar with a hinge heel, which is attached to the metal floor 2 of the pontoon 1 at its bead with a locking screw 12. The rotary mechanism 11 provides rotation of the telescopic frame in two directions — along the bead of the pontoon 1 and along normal to it.

To soften the external mechanical effects on the shell 3 in contact with the bottom of the reservoir and restore the stabilized vertical position of the telescopic frames with respect to the horizontal surface of the pontoon 1, each frame is provided with two spring dampers 13o

Spring-loaded shock absorber 13 is a hollow rod tightly closed at the ends with metal inserts (not shown). Both inserts are internally connected to a spring. Moreover, one of the inserts moves freely inside the hollow rod along with the spring and is rigidly connected to the telescopic frame, and the other input is rigidly fixed on the end of the hollow rod and connected to the wall of the pontoon 1.

The bollard 14 is a paired pendulum with a common base rigidly connected to the metal flooring 2 of the pontoon 1, and serves to fix the ends of the eight-overlaying fastening cable 4 of the sheath 3.

Netting canvases 15 serve as an artificial substrate for caviar and larvae for the period of spawning of fish until the moment of complete emergence of the larvae. For manufacturing1604303

The laziness of nettings 15 use nylon trawls and seines.

The floats 16, aeration pipes 17 and weights 18 are attached to the net sheets 15 along their entire length. Floats 16, filled with compressed air from the pumping station 20, serve to maintain the net sheets 15 in a floating state during installation and operation of the device. Aeration pipes 17 have perforations along the entire length and serve to supply compressed air from a pump-compressor station 20 with water aeration Gruel 18 as well as aeration pipes. 17 pipes are connected through a floating pipe 21 to a pump-compressor station 20 and serves for ballasting the device by filling them with a ballasting filler, such as water.

The spacer elements 19 are embodied as separate tubes of plastic material with a floating core and ensure that the netted sheets 15 are located at a fixed distance from each other, preventing caviar and fish larvae from moving the device.

The pump-compressor station 20 is installed on the pontoon, connected by floating pipelines 21 with floats, 16, aeration pipes 17 and weights 18. The pump-compressor station 20 serves to supply air to the floats 16 and aeration pipes 17 and water to sinkers 18.

The installation and operation of the device is carried out as follows.

Initially, pontoon 1 with reels 5 and 6, sheath 3, telescopic frames, pump-compressor station 20 installed on it is lowered from the shore, as well as 2 nettings 15 with floats 16 laid on its metal flooring, aeration pipelines 17 and sinkers 18.

Prior to spawning, the device is transported to the place of installation and installation of netting cloths 15 with floats 16, aeration pipes 17 and weights 18, installation of spacer elements 19 in a pond. Installation of spacer elements 19 is passed through spacer elements 19 (not shown) float them at the same time

16, the weights 18 and set in a fixed position. In addition, floats and sinkers are connected through floating pipelines 21 to a pump and compressor station 20 located) {a pontoon 1.

For the period of spawning, depending on the specified operating conditions, the nettings 15 are installed at the bottom. or at the surface of the reservoir, for which compressed air or ballast filler is supplied to the respective pipelines.

After spawning, the device can be used as a cage.

For this purpose, the pontoon 1 is installed directly above the net cloths 15 with caviar deposited on them and the floats 16 are fixed under the metal flooring 2 of the pontoon 1. On the pontoon 1 the telescopic frames are installed in a vertical position.

After that, the curvilinear rods 9 of the telescopic frames (except the extreme telescopic frames installed on the ends of the pontoon 1) are oriented;

Then the telescopic frames are lowered overboard of the pontoon 1 using the rotary mechanism 11, secured with a locking screw 12 in a vertical position, and each of them is connected to a two spring shock absorber 1 13 located symmetrically on both sides of the base of the telescopic frame on the sides of the pontoon 1.

The rods 9 of the extreme telescopic frames on both sides of the pontoon 1 are oriented with a concave part inside the pontoon 1 and also fix the working position with the collet clamps. After that, the rods 9 of the two extreme telescopic frames located on the opposite sides of the pontoon 1, the cable 4, passed through the latches 10. The cable 4 is connected at one end with the edge of the material. The shell 3 wound on the drum 5 and the other with the drum. 6

Next, two end-mounted telescopic joints j-oyTa at the stern of the pontoon 1 are simultaneously lowered using fastening mechanism 11, fixed in vertical position by locking screws 12 and, in addition, each of them also connects g to two spring shock absorbers 13 o

On the lowered telescopic frames along the guides, which are curved rods 9 with clamps 10 for the fastening cable 4, move (rewind) the sheath material 3 from the drum 5 to the drum 6. To do this, both Arabans are simultaneously rotated

5 and 6 using a winch 7. When the sheath material 3 is moved under the lowered telescopic frames, free fastening cables 4 are pulled up from the ends of the sheath 3 and mounted on the bollards 14.

In order to create favorable conditions for the development of eggs, larvae and young fish, the device provides feed through the aeration pipelines 17 of the air from the pumping station 20 through the floating pipe 21.

As fish fry develop, it becomes necessary to improve the water strength in the spawning grounds and replace the shell material with a more permeable one, and also to clean the shell cells from silting with fine particles of suspension. For this, the shell material is rewound from the drum 5 to the drum 6 during the operation of the spawning grounds. When performing this operation, the fastening cables 4 of the end edges of the sheath 3 are pre-freed from fastening on the bollards 14. Then they are wound on a drum

The previously used shell material is mechanically cleaned of suspended particles and layered on the walls of the drum 6 together with the free ends of the fastener cable.

The use of the invention will expand the functionality of the device for spawning fish -. means of improving the development of hydrobionts when using it as a breeding ground and cage
