Abstract

This study showed lethal concentrations (LC) of copper forPeneaus penicillatus at various stages of its life cycle were 1000 μg/L for nauplii, 1000 μg/L for Zoea I, 2000 vg/L for Zoea II, 2500 μg/L for Zoea III, 3000 μg/L for Mysis I, II and III and that for almost 100% mortality for postlarvae was 3000 μg/L. For cadmium LC were 100 μg/L for nauplii, 500 μg/L for Zoea I, 1000 μg/L for Zoea II, 2000 μg/L for Zoea III, 2500 μg/L for Mysis I and 3500 μg/L for Mysis II, III and postlarvae. For mixture of both metals, LC were 400 μg/L for nauplii, 1000 μg/L for Zoea I, 2000 μg/L for Zoea II and 3000 μg/L for Mysis I, II, III and post larvae.
