FIELD: hydraulic engineering.
SUBSTANCE: invention relates to hydraulic engineering and can be used for fish farming. Sections of the pool bed increase in area from the lower part to the upper part. On the surface of each section there are holes for installation and fixation of artificial spawning substrate in the form of artificial vegetation elements. Basin part of pool is arranged with slope from upper part to lower part. In the lower part of the pool there is a water-and-fish collection gallery. Pool is equipped with a water-fish dispensing device, a fish-receiver and a fish-launching device to release young fish into a small watercourse.
EFFECT: invention enables to cultivate different types of hydrobionts adapted to habitation at different depths, at different temperature modes and flow rates.
