FIELD: lake fishery, in particular, procedure for attracting of fish into catching zone followed by catching or retention of fish in aeration zone up to the end of perishing period.
SUBSTANCE: method involves establishing aerator-flow generator in direct-flow channel whose front part is communicating with basin and rear part is made dead ended; generating oxygen-saturated water flow and attracting fish into aeration zone, followed by catching fish or retaining fish in basin area up to the end of perishing period; positioning aerator-flow generator on surface and additionally setting catch; adjusting oxygen content in channel and in lake portion adjoining thereto by reducing or increasing distance from aerator-flow generator to leading part of channel.
EFFECT: increased efficiency by reduced zone of distribution of oxygen-saturated water over basin area, decreased consumption of power by employed equipment, reduced sizes of catching equipment and increased catching effectiveness.
