FIELD: hydraulic building, particularly fish passes permitting fish passage through support structures to fish hatchery and growth areas.
SUBSTANCE: fish pass comprises fish-passing canal made as gutter and connecting upper and lower hydrosystem pools. Fish pass also has transversal partitions arranged along fish-passing canal and made of elastic material, drive for transversal partition displacement inside fish-passing canal with respect to canal sides and swimming-in orifices. Upper partition ends are secured to transversal guiding means. Lower ends thereof are fastened to fish-passing canal bottom and define fish-passing system. Swimming-in orifices are made in transversal partition area extent. Transversal partition may move in vertical and horizontal directions with respect to fish-passing canal gutter sides.
EFFECT: simplified fish-pass structure and increased efficiency of fish passage control.
