| Abstract: | - 1.1. The effects of thermal acclimatization at 10 and 24°C on heart rate were investigated on unrestrained soles (Solea vulgaris).
- 2.2. The sensitivity of heart rate to temperature changes induced by temperature acclimatization was higher in cold-acclimatized than in warm-acclimatized soles.
- 3.3. Heart rate of cold-acclimatized fish to temperature changes was not affected by blocking the vagal tone with atropine.
- 4.4. After atropine treatment the ability of heart rate to show thermal compensation decreased in warm-acclimatized soles.
- 5.5. It is suggested that the vagus nerve can function differently at different temperatures.
