Hydraulics of Vertical-Slot Fishways: Nonuniform Profiles ... The performance of two particular designs of vertical slot fishways for two different slopes was studied in a wide range of discharges. Water depths were measured in almost the whole surface of pools. Effectiveness of a multi-slot vertical slot fishway versus ... The present study compares the passage performance of the Iberian barbel, Luciobarbus bocagei (Steindachner, 1864), a potamodromous cyprinid, negotiating two different types of vertical slot fishways (VSF): a standard VSF and a multi-slot VSF (MSF).

Plate 21: Vertical slot fishway retrofitted to a small power ... Vertical slot fishways The basic design of a vertical slot fishway is a rectangular channel partitioned by baffles into resting pools. When the water is flowing the fish swim from pool to pool through vertical slots that are orientated vertically. The advantage of this design is that passage is possible at a variety of water levels (Plate 21 ... Implications of Fish Behavior for Vertical Slot Fishways Design
