Abstract The effects of ozone-produced oxidants (OPO) on three developmental stages of the American oyster, Crassostrea virginica, were evaluated. Straight-hinge larvae were significantly more sensitive to OPO than setting pediveliger larvae. Both larval stages were significantly more sensitive to Chlorine-produced oxidants (CPO) than to OPO. Shell deposition was significantly inhibited at all OPO concentrations for both 15C and 25C acclimated adult oysters. No significant differences were found between the shell deposition response of oysters at the two acclimation temperatures. Faecal matter accumulation was significantly reduced at OPO concentrations > 0 05 mg/litre at both 15C and 25C. It was significantly (p<0.05) greater for 25C acclimated oysters than for 15C acclimated oysters at OPO concentrations < 0.10 mg/litre but not at higher concentrations.
