Method for aeration of water and concentration and catching of fish. RU patent 2286672. |
|
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.
