Effect of water pollutants on the Snake headed fish, Channa punctatus collected from the Sawan Nallaha, Balrampur, U.P

Sawan Nallah is a small lotic water body of Balrampur, U.P., India, which received semi treated effluents of sugar factory and distillery as well as municipal / domestic waste. The aim of the present investigation was to evaluate the toxic impact of these industrial and domestic wastes on water quality of Sawan nallaha and its toxic effect on fish population inhabiting it. The industrial effluent discharged in it caused significant changes in water quality that altered the haematological parameters (RBCs, WBCs, Hb% and PCV) and serum biochemical parameters (protein, free amino acids, glucose and triglycerides). The physico-chemical parameters of water were much higher than the tolerance limit recommended by Central Pollution Control Board of India.
