In this paper, we describe a method employing motion-sensing radio transmitters for recording and identifying behavioural patterns and activity of Atlantic salmon spawning under natural conditions. Simultaneous video monitoring verified recorded activity patterns originating from behaviours such as fighting, nest digging and quivering. The method described here enables more accurate determination of the timing and location of spawning compared to conventional location tracking. Motion-sensing transmitters can also be applied to monitor other species and types of behaviour, and therefore the use and development of such methods deserves further attention in behavioural studies.
