FIELD: fish-breeding.
SUBSTANCE: pool bottom is made in the form of separate sections with transverse two-slope surfaces forming transverse water-and-fish galleries at their interfacing points. Transverse two-pitched surfaces of separate sections of the bottom of the fish-breeding basin are made with a longitudinal slope from the enclosing walls to a longitudinal water-fish-withdrawal gallery, wherein water-fish collection and water-fish-removing galleries are made with walls expanding in plan.
EFFECT: invention makes it possible to exclude fish injuries when emptying the pool.
