The metabolic physiological response to body mass, temperature (12–28 °C) and salinity (20–36 g L −1 ) was examined in this paper. Oxygen consumption rate, which is dependent on environmental conditions, was exponentially related to body mass and varied from 0.045 to 1.11 mg h −1 g −1 . Oxygen consumption rate increased as salinity increased from 20 to 36 g L −1 , and increased with increasing temperature. The effect of temperature gradient between experimental treatments on oxygen consumption rate was evaluated by calculating Q 10 (the Arrehenius relationship for increase with temperature). The Q 10 value within the temperature range from 12 to 16 °C was much higher than the value within the temperature range from 16 to 20 °C, 20 to 24 °C and 24 to 28 °C, indicating a reduced temperature dependence of ascidian metabolism at a high temperature.
