Behavioural transition during the estuarine migration of wild Atlantic salmon ( Salmo salar L.) smolt
Abstract – Ultrasonic telemetry and hydrodynamic modelling were used to study the migratory behaviour of 54 wild Atlantic salmon ( Salmo salar ) smolt captured in freshwater during their downstream migration and tracked in 2 years through a shallow estuary system. A high‐density, fixed array of rece...
