FIELD: pond fishery, in particular, attraction of fish into catching zone for catching thereof.
SUBSTANCE: method involves establishing aerators-flow formers in the vicinity of basins; saturating water with oxygen using flow baffles; attracting fish into aeration zone, with following catching of fish or keeping on water landing area of underfeed basin up to the end of underfeed period; concentrating fish by means of one or two aerators-flow formers whose flows are directed onto basin bank or to construction positioned on basin and made in the form of sloping arc providing for baffling of oxygen-saturated water into open space of basin and slowing down its velocity, and spreading zone. Intensive oxygen saturation of water is enabled by reciprocating small amount of water from flow baffle to aeration zone on water landing area of basin.
EFFECT: increased efficiency in operation of aerators-flow formers and reduced consumption of power for water aeration, concentration, keeping and catching of fish.
