Temporal spawning migration patterns of landlocked Atlantic salmon ( Salmo salar) in a constructed stream
Abstract Landlocked Atlantic salmon (ouananiche, S almo salar ) spawning migration timing varies throughout its range and is influenced by a variety of environmental variables. This study examined the spawning migration time of landlocked Atlantic salmon in a small (4 ha) constructed stream linked t...
