Abstract
The prolonged swimming speed and metabolic rate of 0+ year Arctic grayling Thymallus articus were examined with respect to current velocity, water temperature and fish size, and compared to conditions fish occupy in the river. Oxygen consumption (mg O2 h−1) increased with fish mass and temperature (6–23° C), with a steep increase in metabolic rate between 12 and 16° C. Absolute prolonged swimming speed (cm s−1) increased rapidly with fish size (total length, LT, and mass), however, fish in the natural stream habitat occupied current velocities between 15 and 25 cm s−1 or 4 LT s−1, approximately half their potential prolonged swimming speed (10 LT s−1).
