ABSTRACT
Impact of metal cadmium on the nutritive value of Channa punctatus on exposure to a sublethal concentration (1.12 mg/l) of cadmium (Cd2+) for 15 and 60 days has been studied. Among the various parameters selected, the level of moisture in liver and muscle was increased, while decrease was noted in the level of ash, total proteins and inorganic constituents like iron, calcium, inorganic phosphate, sodium and potassium in both liver and muscle in the two types of exposure. The total lipid level of liver increased, while muscle lipid level was decreased. On the other hand, calcium, iron, inorganic phosphate, sodium and potassium levels showed increase in blood. Zinc and selenium decreased the percentage alterations in all the parameters selected for study. In the two types of exposure, zinc was most effective to counteract the cadmium toxicity to fish as in almost all the parameters insignificant alterations were recorded. In combination studies, protection against cadmium toxicity by the two chemicals became more marked with increase in the tenure of exposure.
