摘　　要：In two penaeid shrimp (Penaeus monodon and Penaeus penicillatus)postlarvae exposed to 10, 50, 500μg/L Cu, Cd and CuLCd(1:1) mixture respectively,the total carbohydrate(CHO), ash, lipid and moisturegradually decreased to a little less than that in the controls without exposure to the twe metals asconcentration increased; but the protein amount gradually increased to a little above that in the controls.Cu caused more reduction in CHO, ash, and lipid as compared to Cd. In contrast, reduction in total constituents was not notable in the case of exposure. to 1:1 mixture of both metals.There were negligiblechanges in all components at 10 μg/L exposure of each metal. Cu, like Zn, probably induced synthesis of specific metal binding proteins (metallothionine) causing increase in synthesis of proteins.In mixture,Cd had antagonistic effects on total composition of constituents in postlarvae.In two penaeid shrimp (Penaeus monodon and Penaeus penicillatus)postlarvae exposed to 10, 50, 500μg/L Cu, Cd and CuLCd(1:1) mixture respectively,the total carbohydrate(CHO), ash, lipid and moisturegradually decreased to a little less than that in the controls without exposure to the twe metals asconcentration increased; but the protein amount gradually increased to a little above that in the controls.Cu caused more reduction in CHO, ash, and lipid as compared to Cd.
