Habitat Choice by Atlantic Salmon Parr in Relation to Turbulence at a Reach Scale
peer reviewed The variables commonly used to describe the physical habitat of Atlantic salmon Salmo salar parr are average velocity, water depth, and substrate. A variety of micro- and mesohabitat models have been developed using these variables to assess habitat quality. However, Atlantic salmon pa...
