Effect of Cu, Cd and Cu:Cd mixture on the biochemical composition of two penaeid shrimp postlarvae
摘要
Abstract
In two penaeid shrimp (Penacus monodon andPenaeus penicillatus) postlarvae exposed to 10
50
500 μg/L Cu
Cd and Cu:Cd (1∶1) mixture respectively
the total carbohydrate (CHO)
ash
lipid and moisture gradually decreased to a little less than that in the controls without exposure to the two metals as concentration 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 negligible changes in all components at 10μg/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.
