Blood is a good bioindicator to determine the health of organisms. In the present investigation, a study was carried out to assess the effect of sublethal concentration (0.002 mg/L) of endosulfan and 2.0 mg/L of diazinon on biology and haematology of the fish, Channa striatus for 30 days. The toxic nature of these pesticides produced ill effects on the biology and haematology of the fish. A significant decrease in the body weight was observed. In blood of the exposed fish, there was a gradual decrease in TEC, Hb, PCV and oxygen carrying capacity. TLC showed gradual increase in number and ESR value showed increase with the duration of exposure.

Abstract


Blood is a good bioindicator to determine the health of organisms. In the present investigation, a study was carried out to assess the effect of sublethal concentration (0.002 mg/L) of endosulfan and 2.0 mg/L of diazinon on biology and haematology of the fish, Channa striatus for 30 days. The toxic nature of these pesticides produced ill effects on the biology and haematology of the fish. A significant decrease in the body weight was observed. In blood of the exposed fish, there was a gradual decrease in TEC, Hb, PCV and oxygen carrying capacity. TLC showed gradual increase in number and ESR value showed increase with the duration of exposure.
