Population structuring in Atlantic salmon ( Salmo salar ): evidence of genetic influence on the timing of smolt migration in sub‐catchment stocks
Abstract – We compared timing of smolt migration for two populations of naturally spawned Atlantic salmon, Salmo salar , originating from an upper catchment (River Tummel) and a lower catchment (River Almond) tributary of the River Tay, Scotland. Smolts from the upper tributary began migration earli...
