Investigating innovations in vertical slot fishway design ... Key words: vertical slot, fishway, fish passage, innovation, Native Fish Strategy A major goal of the Murray Darling Basin Commission’s (MDBC) Native Fish Strategy is restoring fish passage, and one of the most successful mechanisms of doing this is to construct vertical-slot fishways. 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 The goal of the present study is to analyze fish swimming behavior in these artificial environments and to explore its implications in the development of new fishway designs. To this end, a set of experiments has been conducted in an indoor full-scale vertical slot fishway model with different cyprinid and salmonid species.
Vertical-slot fish passage. A pool and weir is one of the oldest styles of fish ladders.Baffles come in variety of designs. The original design for a Denil fishway was developed in 1909 by a Belgian scientist, G. Denil; it has since been adjusted and adapted in many ways.
