Migratory behaviour of wild and farmed Atlantic salmon ( Salmo salar) during spawning
Migratory behaviour at spawning of wild and newly‐escaped farmed Atlantic salmon was analysed by radio telemetry in the River Alta, North Norway. Spawning areas were located by aerial surveys. Farmed females moved significantly more than wild females ( P <0.01). There was no such difference betwe...
