Values of the dissolved oxygen concentration analyzed by the Winkler method were used as an index of respiration. The respiration rates of four individuals with wet weight from 0.20 to 0.30 g and a shell width (shell length) from 9.8 to 11.5 mm were ranged from 0.05 to 0.09 mgO2 L-1 h- 1 at water temperature of 18°C, and other four individuals with wet weight from 0.73 to 1.15 g and a shell width (shell length) from 14.1 to 16.8 mm were ranged from 0.10 to 0.20 mgO2 L-1 h-1 at water temperature of 14°C. The respiration rates per unit wet weight ranged from 0.18 to 0.44 mgO2 g-1 h-1 in small individuals, those were ranged from 0.09 to 0.20 mgO2 g-1 h-1 in large individuals. As a result of this study, it was found that the respiration rate of Corbicula sp. could be measured with simple laboratory wares and procedures.
