The fish Cyprinus carpio exposed to Permethrin technical grade and 25% EC resulted alterations in RBC, WBC, HB, PCV, MCV, MCH and MCHC parameters in both lethal and sub lethal concentrations. The percent changes observed are 44%, 61%, 36%, 44%, 130%, 126% and 99% for technical grade and 75%, 104%, 98%, 89%, 107%, 115% and 107% for 25%EC respectively in lethal concentrations of the parameters studied. Similarly the changes are 65%, 120%, 85%, 80%, 115%, 122% and 106% for technical grade and 52%, 127%, 88%, 76%, 105%, 118% and 111% for 25%EC in sub lethal exposure. These changes are the indices of toxicant action in the fish which is linked to human beings in energy circuit.
