Abstract
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 conditions
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.
