FIELD: hydraulic building, particularly structures permitting fish passage through support structures to fish hatchery and growth areas and to spawning areas.
SUBSTANCE: method for spawning field forming involves arranging spawning substrate on fish pass bottom so that solid multilayer gravel and pebble covering having width equal to channel bottom width is created along the full channel length; forming additional spawning field area by installing several layers of spawning panels with additional spawning substrate, wherein the panels are arranged in horizontal plane and directed so that major panel sides are along longitudinal fish pass axis. Some spawning panels abut shore line along both channel banks. Other spawning panels are arranged in channel bed so that longitudinal axes thereof coincide with channel axis.
EFFECT: creation of efficient spawning conditions for fish living on different levels along channel depth and increased spawning area.
