The utility model relates to a hydraulic engineering and can be used to prevent the fish in the water inlets HPP. Fish protection shelter includes bulk freely permeable frame structure, which is equipped with elements that allow to create the shelter environment, distinguishing it from the surrounding water intake situation in the reservoir zone and therein provide conditions favorable for the orientation and displacement data of fish in a safe area. Shelter is equipped with visual and tactile landmarks and performed illuminated at night as a constant, and the "traveling wave" mode, and is equipped with hydrophones that can alternately operate in either attracts or deters fish mode. Vault performed in two variants: the mobile and stationary. A mobile shelter is set in the zone of maximum concentration of fish. Depending on the intensity of slope can be shelter before HPP entire season or intermittently towed safe zone, for example, to the upper reservoir. Stationary refuge placed in front of HPP water or water intake pumping station on the paths downstream migration of juvenile fish and pave it to a safe place pond.
