FIELD: agriculture.
SUBSTANCE: invention relates to lake fish farming and can be used for annual and perennial cultivation of fish in winter and occasionally winter lakes. Method of growing fish in winter lakes includes the use of the auxiliary reservoir (2) and aerators-flow developers (15,16). Aerators-flow developers (15) are set along the banks of the auxiliary reservoir (2) to create the rotational motion of water in a clockwise (22) or anti-clockwise. The aerator-flow developer (16) is mounted in the water intake channel (3) for water intake from the lake (1) with discharge into the reservoir (2). As an auxiliary one, an aerator-flow developer with electric low-power drive (0.5-1.0 kW) is used or oxygen tank attached to the reinforced hose.
EFFECT: increased fish production of lakes through extensive use of aeration equipment.
