FIELD: fish protection.
SUBSTANCE: complex fish protection device, one of the main working elements of which is a flow former located obliquely, or curvilinearly, or curved to a horizontal plane / to the water horizon in a water body, and/or an inclined, or curved, or curved nozzle and/or a flow former nozzle. The inclined, or curved, or curved arrangement and/or configuration of the flow former 1 and/or the nozzle and/or nozzles of the flow former 2 helps to reduce the likelihood of fish getting into the water intake of the hydraulic structure and/or the water intake device and/or facilitates the direction and/or movement of fish in specific conditions, including, for example, taking into account the bottom topography, coastline, design features of a hydraulic structure and its equipment (for example, a canal, an advance chamber), the hydraulic and/or climatic situation of a water body, depth marks, ichthyological situation (distribution of fish in a water body), etc.
EFFECT: technical result of the proposed device is to optimize the hydraulic regime in a water body, in the area of action of the claimed technical solution and/or in the ability to help reduce the likelihood of fish getting into the water intake of a hydraulic structure and/or a water intake device and/or to facilitate the direction and/or movement of fish for due to the possibility of choosing the optimal location of the flow former and/or the nozzle and/or the nozzle of the flow former.
