Application of pesticides in agricultural practices has elevated the risk of contamination of aquatic habitat and its ambient environment. Considering the fact, the present investigation was carried out to study the impact of sublethal concentration of chlorpyrifos exposed after regular interval of 24, 48,72 and 96 hrs on erythrocyte sedimentation rate of freshwater fish Channa striatus. This is common edible fish abundantly found in local river Manjira river district Hyderabad. The Godavari platoon is well flourished by various crop cultivations. Hence the former using chlorpyrifos as an effective insecticide to control various pests. Ultimately the excess run of water carries chlorpyrifos reaches to the aquatic habitat and disrupting the aquatic biota. In present study, The haematological analysis showed significant increase in erythrocyte sedimentation rate of treated animals as compared with control.
