Abstract

River Aami is known as Lifeline of Magahar, originates from Sikhaira Tal, Siddharth nagar. The river passes through, Siddharth Nagar, Basti, Sant Kabir Nagar and Gorakhpur. It traverses approximately 102 Kms. and ultimately confluences in the River Rapti near village Sohagaura of tehsil Bansgaon of district Gorakhpur. During its journey, it receives industrial effluents at several locations. Some of them are Rayana Paper Board industries limited, Khalilabad and GIDA in Sahjanva which is chain of several industries namely textile, steel plants, india glycol limited (IGL) etc. The aim of present study was to evaluate the extent of toxicity posed on the river water due to various industries situated on the river bank and its influence on biochemistry of fishes and for this study Cyprinus carpio was selected as this fish is widely present and inhabit Aami river and its availability is adequate. Several important sites of river Aami were selected that mark the boundaries of the flow root of this river and exoeriment was set eventually. The physico-chemical properties and parameters were tested and taken in consideration to define the quality of water. It was found that, the temperature, pH, colour odour, TS (total solids), TSS (total suspended solids), DO(dissolved oxygen), BOD(biochemical oxygen demand), COD(chemical oxygen demand),was found much different and were not in accordance with recommended tolerance limit by WHO. In biochemical profiling, an alteration in blood and serum parameters was clear indication of the physiological stress imposed on fishes by pollution i.e. decrease in level of protein, AchE (acetylcholine esterase) and increase in level of glucose and Transaminase enzymes (sGOT and sGPT).
