Abstract

Effects of sublethal concentrations of decamethrin on food intake, growth and respiratory metabolism
were studied in Cyprinus carpio. An increase in the concentration of the pesticide gradually reduced
feeding, absorption and conversion. The efficiency of absorption did not vary much; it remained around
93.4%. Sublethal concentrations resulted in significant reduction in gross and nci conversion efficiencies.
However, oxygen consumption and opercular beats gradually increased with increase in sublethal
concentration of the pesticide. Poor growth response might be due to the inhibition of food intake and
increased metabolic expenditure under sublethal concentration of pesticide
