FIELD: agriculture.
SUBSTANCE: invention relates to fish farming. The method provides the production of planting material to the auxiliary water reservoir, and from it into the lake for feeding, the concentration of fish in the auxiliary water reservoir, fishing and preservation from suffocation. The fish is concentrated, caught and saved from suffocation in the deep auxiliary water reservoir cleaned from bottom sediments, which is located on the leeward side or the area of the lake between the windward and leeward shores of the lake with the depth of 3-4 m or more.
EFFECT: invention provides fish farming in lakes with low oxygen content with minimal costs.
