“…The present study focuses on the movements of the adult trout. Most of the studies were carried out by mark-recapture experiments (Biittiker & Matthey, 1986) or by radio telemetry (Nettles et ul., 1987). This work reveals that generally trout movement is restricted to the area where juveniles are stocked or which are near the mouths of the spawning rivers.…”

adult lake dwelling brown trout (Sulmo /ru//u L.) were tagged with ultrasonic transmitters and tracked almost continuously for up to 13 days. Two behaviour types were observed: (a) random movement in locally restricted areas and (b) excursions of up to 40 km distance. Swimming activity during the day was significantly higher than at night in most experiments. In summer swimming depth ranged between 8 and 16 m, and in winter between 0 and 3 m. The preferred water temperature was about 14" C in the thermally stratified waterbody. During the experiments mean swimming speed ranged between 0.3 km h ' (0.1 bodylengths s I) and 0.9 km h-l(O.6 bodylengths s I).
