Changes in the ventilation volume and the amount of oxygen uptake were examined in the Mediterranean blue mussel Mytilus galloprovincialis with feeding Chaetoceros gracilis, at a density of 20,000 cells/ml. For the blue mussels without feeding, the ventilation volumes at 15, 20 and 24degC were 2.55, 4.46 and 6.01 l/min/kg WW (per wet weight of soft part of body), respectively; for those with feeding they increased to 18.4 (7.2 times that with feeding), 18.6 (4.2 times) and 19.04 l/min/kg WW (3.2 times), respectively. The amount of oxygen uptakes with feeding at 15, 20 and 24degC were about equivalent to those without feeding (0.506, 0.683 and 0.753 ml/min/kg WW). These results suggested that the Mediterranean blue mussel with feeding increased the ventilation volume without an increase in the amount of oxygen uptake.
