Schwalme, K., W. C. Mackay and D. Lindner (1985). Suitability of vertical slot and Denil fishways for passing north-temperate, nonsalmonid fish. Canadian Journal of Fisheries and Aquatic Sciences. 42:1815-1822.
A vertical slot fishway and two Denil fishways (of 10 and 20% slope) built into a weir on the Lesser Slave River (55° 18'N, 115° 45'W) were studied from May 12 to June 25, 1984, to determine how effectively these designs pass north- temperate, nonsalmonid fishes. Thousands of spottail shiner Notropis hudsonius, substantial numbers (> 100) of northern pike Esox lucius, longnose sucker Catostomus catostomus, white sucker Catostomus commersoni, immature yellow perch Perca flavescens, and lesser numbers of burbot Lota lota, adult yellow perch, lake whitefish Coregonus clupeaformis, and trout-perch Percopsis omiscomaycus ascended the fishways. Walleye Stizostedion vitreum and goldeye Hiodon alosoides, although probably moving extensively through the river, did not use the fishways.
