Abstract :
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.
