Fishway ascent. Description. Brown trout (Salmo trutta), Iberian barbel (Luciobarbus bocagei) and Iberian nase (Pseudochondrotoma polylepis) ascending the vertical-slot fishway model built in Hydraulics Laboratory (Centre for studies and experimentation on public works, CEDEX). Hume-ward bound - detailing the Sea to Hume Fishway… A vertical slot fishway comprising a set of steel slotted baffles, constructed in modules to occupy a complete sluice bay and provide either part or full depth fish passage. A rock ramp has been installed where aggregations of small fish have been observed, followed by an adjacent small-fish vertical slot.

The main advantage of the vertical slot fishway is in its ability to handle large variations in water levels. Usually the difference between water levels in successive pools is 300 mm for adult salmon and 200 mm for adult freshwater fish. Vertical slot fishways usually have a slope of 10%.
