抄録

During an acute drop of ambient temperature from 25°C to 5°C at the rate of 0.3°C•min^-1, total loss of equilibrium, decrease in heart rate and remarkable extension of time elements of ECG (P₁, PQ₁, QRS₁ and QT₁) were observed in carp Cyprinus carpio acclimated at 25°C. Oxygen con-sumption and oxygen utilization significantly decreased, while there was no significant change in minute volume of gill ventilation.During restoration of ambient temperature from 5°C to 25°C at the rate of 0.2°C•min^-1, recovery from loss of equilibrium, increase in heart rate and shortening of time elements of ECG were observed. When the temperature was restored to 25°C, frequency and minute volume of gill ventilation and oxygen consumption were higher than the initial level probably owing to oxygen debt during the low temperature period.
