FIELD: hydraulic structures, particularly fish passes for permitting fish passage through support structures to fish hatchery and growth areas and artificial hatchery ponds.
SUBSTANCE: fish-farming facility includes water pass made as channel with head part communicating with upper pool of hydrosystem and mouth part communicating with lower pool, rough members located on channel bottom along the full length thereof, additional flow paths with upper and lower parts communicating with water pass, larva ponds, discharge channels and regulating gates. Additional flow paths are parallel to water pass and have common inlet and outlet structures. Bottom levels of additional flow paths are higher than that of water pass. End part of additional flow paths communicates with discharge channel and with larva pond which in turn communicates with water pass through additional discharge channel. Discharge channels, inlet and outlet structures of additional paths are provided with regulating gates.
EFFECT: provision of effective hatchery conditions.
