Changes in the ventilation volume and the amount of oxygen uptake associated with feeding Chaetoceros glacilis were examined in the pearl oyster Pinctada fucata martensii. The ventilation volume began to increase at feed densities of 80-97 cells/ml and the increased volume persisted at densities of 119-15,324 cells/ml for 8 hours or more. However, the volume changed repeatedly at densities of 33,021 cells/ml or more. At a densities of 10,000 cells/ml, the volume increased to 2.8 times that without feeding. Nevertheless, the amount of oxygen uptake was not affected by the feed, and was approximately held constant.
