FIELD: fishery, in particular, catching of fish in lakes. SUBSTANCE: method involves creating aeration zone in basin by means of flow forming aerator; providing concentration of fish in aeration zone by switching off aerator for at least one day; controlling oxygen content in catching zone; performing first throwing of net under ice, when oxygen concentration is reduced to value causing hard breathing of fish; switching on aerator upon withdrawal of net and completion of catching process. As concentrated fish is gradually caught, aeration stop time is gradually increased. EFFECT: increased efficiency and simplified method.
