Juell, J. E., & Westerberg, H. (1993). An ultrasonic telemetric system for automatic positioning of individual fish used to track Atlantic salmon (Salmo salar L.) in a sea cage (Vol. 12).
Zusammenfassung: A telemetric system for automatic positioning of individual fish in the vertical or horizontal plane is described. The position of a transmitter in a fish is computed from the difference in arrival time of the ultrasonic signal to a fixed array of hydrophones. Sources of error in positioning are discussed. In a preliminary study, the resolution of the system in time and space was adequate to monitor the behaviour of adult salmon in a sea cage. At moderate stocking density the salmon was swimming continually in counter-clockwise circles and diel rhythms in swimming speed, depth and path-radius were observed. With only 30 fish in the cage this stereotype behaviour broke down. Few or no visits into the feeding area during some feedings indicated a variable feeding motivation.
