The rate of reaction of pollutants entering the water or the detrimental effects on the aquatic organisms are generally influenced by various environmental factors such as total alkalinity, hardness, dissolved oxygen, ph, turbidity, temperature etc. In aquatic environment the physico-chemical changes are occurred due to the release of effluents. Discharge of different kinds of waste to aquatic system also creates undesirable changes in fish such as physiological and haematological changes. Therefore, quality of water plays an important role for the survival and development of aquatic animal. All this necessitates the importance to study the physico-chemical parameters of processing effluent discharged to the surrounding water bodies. The experiment was set for 70 days in four treatment groups i.e. 0.25 % (T1), 0.5% (T2), 0.75% (T3) and 1 %( T4) and one control group i.e. 0% (T0), with triplicates following completely Randomized Design (CRD). Various physicochemical parameters like colour, odour, pH, DO, hardness, total alkalinity, BOD, COD, phosphate-phosphorous, TS and TDS were determined using standard method. From the results of analysis, it is inferred that the physicochemical parameters were found to be increased from the control set except the dissolved oxygen which was found to be decreased. During the study it was also found out that the effluent characteristics are not within the permissible limits for fish culture.Not Availabl
