FIELD: hydraulic structures, particularly fish passes permitting fish passage through support structures to fish hatchery and growth areas.
SUBSTANCE: fish pass comprises waterway made as gutter with head connected to upper pool of hydrosystem and mouth communicated with lower pool thereof. Fish pass also has roughness members distributed along waterway length and through zigzag channel extending along waterway length. Through zigzag channel bottom mark is below than that of waterway. Through zigzag channel extends along sinusoid curve having constant amplitude. Roughness members are connected to waterway bottom in areas adjoining through zigzag channel from both sides thereof. Roughness members are of different size and shape.
EFFECT: possibility to create hydraulic conditions, which facilitate fish movement along fish pass.
