FIELD: hydraulic engineering. ^ SUBSTANCE: invention relates to fish facilities designed to pass spawners through retaining structures to placed of spawning and fattening. Proposed fish guide includes bottom sill installed at acute angle to longitudinal axis of fish facility and adjoining, by upper end face part, inlet part of trough-fish storage, device to regulate flow along sill in form of water pass holes made lengthwise the bottom sill which is installed over entire width of wasteway part with its lower end face part adjoining bank edge and formed by blocks discretely arranged lengthwise. Blocks are displaced in plan relative to each other forming vertical wasteway holes in between, block being installed in parallel with overlapping of water pass holes formed by lower end face part of block arranged higher and upper eng face part of block arranged lower. Width of water pass holes is less than minimum cross size of midship section of migrating fish. Invention makes it possible to create hydraulic conditions in zone of location of guide providing effective movement of fish to inlet of fish facility owing to from water pass holes increasing attraction and guide effect. ^ EFFECT: provision of effective movement of fish. ^ 4 cl, 8 dwg |
