FIELD: hydraulic structures, particularly fish passing facilities to permit brood fishes to pass through retaining structures to spawning and meadow areas.
SUBSTANCE: fish-passing facility includes power supply unit, the main fish accumulating fume, stimulating device mounted on horizontal guide members parallel to side fish accumulating fume walls, ichthyological area arranged between upper and lower gates of lock chamber and additional fish accumulating fume installed coaxially with the main one and performing movement relative side walls thereof by drive. Initial part of additional fish accumulating fume has netted gate. Side walls thereof adjoin that of the main fish accumulating fume. Upper edges of additional fish accumulating fume are installed on additional guiding members by means of rollers.
EFFECT: provision of effective conditions in lower hydrosystem pool to attract fish directly from search zone due to reciprocal moving additional fish accumulating fume relative the main one.
