Factors affecting the within-river spawning migration of Atlantic salmon, with emphasis on human impacts
Abstract We review factors affecting the within-river spawning migration of Atlantic salmon. With populations declining across the entire distribution range, it is important that spawners survive in the last phase of the spawning migration. Knowledge on the factors affecting migration is essential f...
