Pesticides influence various physiological and biochemical parameters of fishes (Mckim et al. 1970, Rajik et al. 1983). In the present study, certain observations on blood – haemoglobin percentage(Hb %) , total erythrocyte count (TEC) and total leucocyte count (TLC) have been made. These parameters were observed in normal as well as dichlorovos (organophosphate pesticide) are treated Heteropneustes fossilis. It was noted that by increasing the dose of dichlorovos, significant fall in TEC and Hb % values, while the values of TLC increased gradually compared with control.
