Development and pollution are two interrelated processes that have been causing great concern to the planners with the increasing population in the country. The quality of waste water generated has been increasing beyond treatment capacities, as a result of huge quantity of waste water finds its way into natural water bodies like river, streams, canal, ponds etc. and finally into sea causing alarmingly high rate of pollution and environmental hazards. A survey and the analytical work on waste water especially sewage characteristics of a sewage fed fisheries at Varanasi were due to assess the sewage treatment capabilities of aquaculture and production potentialities of sewage. It was observed that aquaculture itself could remove BOD, COD, nitrogen, phosphorus, heavy metal, suspended solids and bacteria to the extent of 85%, 72%, 70%, 51%, 98-100%, 97% and 93% respectively at the end of its operation and thus to save the environmental pollution. Fish production observed at the rate of 4-5 t/ha/year without conventional feed and fertilizer. It is desirable to remove off flavour and bacterial load, fishes should be kept in fresh water containing marketing pond atleast for 10-15 days before sending it to market.
