Abstract

Water pollution may be defined as any impairment in its native characteristics by addition of anthropogenic contaminants to the extent that it either cannot serve humans for drinking purposes or to support the biotic communities. A change in the quality of water by the presence of contaminants makes it potentially harmful to life forms, instead of sustaining them. The entry of toxicants into aquatic media may affect the water quality parameters which in turn leads to changes in the haematological variables of fish and other aquatic lives due to close association with the external environment. The blood parameters were analysed in the fish, Labeo rohita theLC50 value was determined when the fish was exposed to detergent tide. The parameters like RBC, Hb, MCV,MCH and PCV were decreased and WBC have been increased in the fish.
