SU97460A1 - Ground round pool for young fish - Google Patents

Description

The subject of the invention is a round pool for fry of fish with a continuous flow of water, using a feeding tray and a drain pipe.

The proposed ground round basin makes it possible to bring the content of young fish in it to natural conditions and is distinguished by the simplicity of the device and the simplicity of its production.

A distinctive feature of the proposed pool is that the littoral (ground) zone is formed along its contour, the bottom of which is connected to the basin pit by inclined annular slope, and the feeding tray is inserted at a distance from the center of the basin tangentially and at its bottom .

Fig 1 shows a section of the proposed pool along the axis of the nutrient tray and the drain pipe; in fig. 2 - view it in the plan.

A ground round pool with a continuous flow of water, serving to raise fry of sturgeon, spawning, incubating half-passing eggs, is arranged in the ground without attaching its slopes and bottom. The basin is buried in the ground and a berm is left around it for ease of maintenance.

The zone / formed along the outer contour of the basin is a littoral (shallow) zone; it is adjacent to the basin’s pit by a circular inclined descent 2 (slope). The water surface area of the shallow water area accounts for about 40% of the total water surface area in the pool.

The water supply to the pool from the supply channel 3 is carried out through the open gateway 4, in front of which the frames 5, covered with a grid, are installed, which prevent the pool from entering it.

The direct rQT-gap 4 starts the wooden nutritious open tray 6, which was inserted at a distance from the center of the basin punitively.

At the bottom of the chute, the transverse bars 7 are reinforced, creating swirls and water drops that enhance the aeration of the latter.

Tray 6 is terminated by a guide nozzle 8 of roofing iron lowered to the surface of the water, which serves to soften the impact of the water jet falling from the tray and to give it the desired direction.

The water discharge device consists of a water intake chamber I above which a removable mesh cylinder 10 is installed, and a drain pipe // laid under the bottom of the basin. For the time of the removal and cleaning of the cylinder 10, the flow of water to the pool and its discharge are stopped, and the opening of the water intake chamber is closed with a net that is pressed onto the metal frame.

For the periodic cleaning of the mesh cylinder 10, a small removable bridge (ladder) 12 is arranged from one of the banks to the pool center.

Claims (2)

1. A ground round pool for young fish with a continuous flow of water, with the use of a feeding tray and a drain pipe, characterized in that, in order to bring the content of young fish in it to natural conditions, the littoral is formed along its outer contour the zone, the bottom of which is connected to the basin of the basin by an inclined annular descent. 2. A pool according to claim 1, characterized in that, in order to enhance aeration and create a circular flow of water in the pool, a system of transverse bars is fixed at the bottom of the nutrient tray, and its introduction is made tangentially at some distance from the center of the basin.
