Sewage contains huge quantities of different types of nutrients which are utilized in fish culture; hence recycling of this wastewater in a productive way is the acute demand of the future of aquaculture. Raw sewage cannot be used for a fish culture so it is treated at 3 levels namely mechanical, chemical and biological. These treatments reduce the microbial contaminants load and optimize the physicochemical parameters of sewage. Different aspects of fish farming such as seed quality, species selection, stocking density, harvesting technique, and marketing of fishes were considered. Various kinds of fish species cultured including Catla catla, Heteropneustes fossilis, Tilapia mossambicus are almost safe for human consumption after following the guidelines of WHO. Sewage fed culture has boundless potential in the field of aquaculture to solve the water scarcity problems and increased farm income.
