Heart rate and swimming activity as indicators of post-surgical recovery time of Atlantic salmon (Salmo salar)
Abstract Background Fish telemetry using electronic transmitter or data storage tags has become a common method for studying free-swimming fish both in the wild and in aquaculture. However, fish used in telemetry studies must be handled, anaesthetised and often subjected to surgical procedures to be...
