Underyearling Arctic charr were acclimated to six temperatures between 6 and 21·5°C and thermal tolerance and resistance were tested after an acclimation period of at least 2 weeks. Resistance times were influenced by acclimation temperature and the highest upper incipient lethal temperature was 23–24°C. An upper limit for cultivation of Lake Inari charr is suggested to be 21°C which is the intercept of the function which represents the upper limit of the thermal tolerance zone.
