In the biodegradation process, role of soil in waste treatment was evaluated. For this purpose, 50% domestic sewage, 750 mg l -1 sewage sludge and 500 mg l -1 night soil were selected for treatment. Each of these treatments was inoculated with four brooders of cladoceran for their multiplication and their subsequent performance was assessed for a period of 30 days. Presence of soil definitely increased the production of cladoceran. As such, the highest (5600 l -1) cladoceran population was noticed in culture systems having soil bed and treated with domestic sewage while the lowest (20 l -1) being in control. The results have depicted significant role of soil in maintaining favourable water quality condi- tions for good aquaculture. The concentration of organic carbon, phosphorus, nitrate-nitrogen and ammonia-nitrogen reduced significantly (p <0.05) in each culture medium from the initial levels. The study suggests that soil could be used in live fish food culture system that is helpful in waste recycling.
