FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic works designed for passing fish spawners through retaining facilities to places of spawning and fattening. Proposed fish contains fish conduit connecting upper and lower ponds of hydraulic works made in form of trough, perforated partitions installed on vertical axles for turning and displacement widthwise the trough by means of drive relative to cross guides provided with slot for displacement of axles of partitions, and swim-in holes formed by extreme vertical end faces of partitions. Perforated partitions are made symmetrical relative to vertical axles and are installed separately in section line of trough for independent displacement in slots of cross guides.
