Abstract: The state Assam has an excellent sub-tropical climate for development of freshwater fish culture. Barpeta is the highest fish seed producing district in Assam. The district is a low-lying flood affected area having a lot of water bodies which is used for the purpose of fish culture, irrigation and domestic uses etc. In the present study collected water samples were subjected to physico-chemical analysis in order to evaluate the quality of water in the ponds of the area. This paper deals with the comparisons of water quality assessment of culture and capture fishery on thirteen Physico-chemical parameters such as water temperature, pH, Dissolved Oxygen, Free Carbon dioxide and Total Hardness, Chlorides, Alkalinity, Total dissolved solid and Electric conductivity following standard methods. The study reveals in both the capture and culture fisheries that water quality index is found as 68.8 and 62.4 respectively indicating poor water quality status, which suggests for a proper management of the fisheries to yield better growth dynamics.
