FIELD: fish farming.
SUBSTANCE: hydraulic engineering construction, namely fish-passing facilities. The fish-passing and spawning channel includes an entrance head made in the direction of fish movement, a fish-passing and spawning path with areas for rest and spawning of fish, equipped with a head regulator. The section from the head regulator to the junction of the fish-passing and spawning path of the channel with the upper pool of the reservoir is made of a trapezoidal cross-section, deepening and widening, with an increasing cross-sectional area of the water flow in the direction of the fish exit.
EFFECT: invention allows fish breeders to pass through the retaining facilities of river hydraulic structures to spawning places.
