Abstract: The present study is aimed to investigate the water quality index, using seven important water parameters like pH, dissolved oxygen, electrical conductivity, total alkalinity, total hardness, total dissolved solids and nitrate nitrogen in Sewage fed aquaculture system, Nalban East Kolkata Wetland, West Bengal, India a Ramsar site. The study was carried out for nine months from July 2016 to March 2017. Three sites S1, S2, S3 were selected randomly and monthly water samples were collected. The physico-chemical parameters like pH, dissolved oxygen, electrical conductivity, total alkalinity, total hardness, total dissolved solids and nitrate nitrogen were analysed following the standard procedures (APHA, 2012). Water quality index was calculated by applying weighted arithmetic water quality index. All the physico-chemical parameters except total hardness were within the desirable range for fish culture. The water quality index recorded in S1, S2 and S3 as 141.787 and 197.519, 150.583 and 201.376 and 146.371 and 276.688 respectively, which is unsuitable for human use. The highest value of water quality index was recorded during March, 2017 and lowest during September, 2016. The result indicates the deterioration of water quality which needs continuous monitoring to design the suitable measures for multiple use of this water body.
