ALTERATIONS OF BIOCHEMICAL INDICES IN CYPRINUS CARPIO (LINN.) EXPOSED TO SUBLETHAL CONCENTRATIONS OF CYPERMETHRIN (25%EC)P. NEELLMA L. CYRIL ARUN KUMAR1 AND N. GOPALA RAOAbstract Freshwater fish Cyprinus carpio were exposed to sub-lethal concentrations of synthetic pyrethroid, cypermethrin (25% EC) for 5, 10 and 15 days. Biochemical parameters such as carbohydrate, protein and lipid content in gill, muscle and liver were studied. All biochemical parameters were found to decrease as a function of sublethal concentrations of pesticide cypermethrin was evidenced. Dose as well as exposure period depended statistically significant (P<0.05). Reduction in biochemical contents in gill, muscle and liver of Cyprinus carpio are advocated as bioindicators of water borne pesticide stress.
