Effects of Chlorine-Produced Oxidants on Survival of Larvae of the Oyster Crossostrea virginica

Abstract

Effects of chlorination on two larval stages of C. virginica were studied in flowing estuarine water. Mortality of straight-hinge and pediveliger larvae was directly related to increased concentrations of CPO and extended exposure time. Pediveliger larvae were generally more resistant to CPO than straight-hinge larvae, especially with longer exposure time. Equations for predicting mortality under different conditions of time and CPO concentration were developed using these data.
