To evaluate the effect of ozone-produced oxidants on respiration of the Pearl Oyster, Pinctada fucata, the amount of oxygen uptake (Vo2), the ventilation volume (Vg), the oxygen utilization (U) and the gill cilia movement (SP) were examined before, during and after exposing to ozoned seawater at various concentrations of the oxidants for 2 hours. The exposure decreased all the four criteria markly or to zero. And when the oxidant concentration reached to 5.80 mgO3/l, SP did not recover even 20 hours after the shell being returned to normal seawater. However Vo2, Vg and U recovered to the normal levels 3 hours after being returned to normal seawater when the oxidant concentration were equal to or less than 6.12 mgO3/l. The results suggested that the 2 hours exposure of the Pearl Oyster to ozoned seawater at equal to or less than 6.12 mgO3/l would not likely to cause the damage of the tissues of the shell.
