Wastewater aquaculture, as practised in the East Kolkata Wetlands (EKW), has attracted much international attention as a model system for the reuse of urban wastewater and resource recovery. At present the multifunctional wetland ecosystem covers approximately 12,500 ha, and is comprised mainly of 254 fisheries managed for wastewater aquaculture, agricultural land, horticultural plots and residential areas. It constitutes a unique system of resource recovery, in which nutrients are extracted from the city’s wastewater through fish farming and agriculture.
