A study was conducted to explore the potential for concurrent rice-fish culture in the wetland rice fields of Assam, North East India. For the present study, a representative wetland located in Cachar district of Assam, North East India was selected. Water quality parameters such as water temperature, dissolved oxygen, biological oxygen demand, pH, free carbon dioxide, and nutrients like nitrate-N and phosphate-P were analyzed. Besides, qualitative and quantitative estimation of both phyto- and zooplankton communities in the rice fields were also done.
