Abstract

Methomyl, a carbamate pesticide, proved to be toxic to Cyprinus carpio var. communis even at sublethal level (2.014 ppm). Na+, K+ - ATPase activity from both gills and plasma showed significant reduction throughout the experimental period. The per cent change in the enzyme activity was more drastic in the case of plasma. The results are discussed in relation to the significance of the above enzymes as non-specific biomarkers against environmental stress.
