Abstract

We examined the effects of temperature on ventilation volume (Vg), the oxygen utilization (U) and the amount of oxygen uptake (Vo2) in the abalone Haliotis (Nordotis) discus discus. The experimental water temperature was elevated at a rate of 3°C/hr from the acclimated seasonal temperatures: 13°C (March), 18°C (May) and 22°C (June). Vg, U and Vo2 increased with the elevation in experimental water temperature at the three seasons. However, Vg, U and Vo2 did not change in spite of the elevation of the experimental water temperature at any season. From the results, the type of the temperature compensation of Vg, U and Vo2 in the abalone were classified into Precht type 4 and Prosser type I.
