“…Progress has recently been made in the study of behaviour of fish by the use of ultrasonic tracking techniques in which a transmitter is attached to individual fish (Trefethen, 1956;Walker et al, 1971;Young et al, 1972;Tesch, 1972;Hawkins et al, 1972).…”

A new type of miniature ultrasonic telemetry transmitter weighing less than 4 g underwater and usable on fish of less than 0.5 kg weight is described. The signal consisting of a sound pulse triggered by the QRS spike of the electrocardiogram is detectable at ranges to 400 m. Continuous records lasting 7 days were made of cardiac rhythms of brown trout. Mean heart rates were low indicating a metabolic rate of not more than 1.55 times the basal metabolic rate. Maximum heart rates were rare, occupying less than 0.5 % of the time;there was no evidence of build up of oxygen debt due to periods of high activity. Following a settling down period after the attachment of the transmitter, the fish exhibited a diurnal rhythm with higher heart rates during the day. The transition from day to night heart rates and vice versa in one fish was shown to anticipate solar altitude change by half-hour. Missing heart beats (cardiac inhibitory reflexes) are discussed as indicators of a sensory input, but they are not reliable indicators of feeding activity. It is concluded that stamina is not important for normal day to day survival of adult trout and the influence of various ecological factors is discussed.

“…The plaice, which were fitted with transponding acoustic tags were released in the Southern Bight of the North Sea and followed by RV 'Clione' using sector-scanning sonar (Greer Walker et al, 1971;Greer Walker et al, 1978). Fish were tracked continuously for periods of 22 to 65 h off the East Anglian coast in the area between 51°57-5'N to 52°57-5'N and 01°474'E to 03°18-7'E ( Figure 1).…”

Adult plaice (Pleuronectes platessa L.) in the southern North Sea use selective tidal stream transport to migrate between their summer feeding grounds and winter spawning grounds. The fish come up into midwater when the tidal stream is flowing in one direction, but remain on the bottom when it is flowing in the opposite direction. This behaviour can theoretically save energy, which can be used for growth or reproduction. Alternatively, it may provide a transport system by means of which fish that have no ability to navigate over long distances can be conveyed reliably between their feeding grounds and spawning grounds.

“…Recently, similar techniques have been used for studying movements of marine fishes (Walker et al, 1971;Hawkins et al, 1973) in British coastal waters, and for monitoring sea trout movements in Scottish sea lochs (N.E.R.C. Bulletin, June, 1973).…”
