Abstract:
The present study deals with the effect of Copper on hematological parameters of a live cat fish species Heteropneustes fossilis (Bloch) under optimal laboratory and physicochemical condition. Most of the physicochemical parameters like DO, FCO2, pH, TA and TH of the experimental aquariums are observed to be maintained at the productive range. During the experiment, LC50 was determined which is 4.5 mg. l-1 (CuSO4 as Cu) and thereafter fishes were treated with sub lethal LC50 concentration (1/5th of LC50 concentration i.e. 0.9 mg.l-1 CuSO4 as Cu) and examined the haematological alteration after a treatment period of 24 hrs, 48 hrs, 72 hrs and 96 hrs interval. The result reveals that there is decrease in RBC and Hb% during the investigation period. Moreover significant increase of WBC number has been observed with increasing time during the investigation period.
