Density-dependent habitat selection by juvenile Atlantic salmon ( Salmo salar ) in experimental riverine habitats
We investigated habitat use of Atlantic salmon (Salmo salar) parr in experimental riverine enclosures made up of pool, riffle, and run habitats over a range of densities (0.1-1.25 fish·m -2 ) to test the implicit assumption in habitat modelling that habitat selection does not change with population...
