Heart rate and swimming activity as stress indicators for Atlantic salmon (Salmo salar)
We investigated the relationship between telemetry measurements of heart rate and swimming activity and the physiological status in farmed Atlantic salmon (Salmo salar) to assess the potential to use telemetry measurements as proxies for stress.
