Abstract

Sewage sludge - a common urban refuse was tried as supplementary feed for the
fish {Cyprinus carpio L average weight 4.9 g) @ 0, 50, 75 and 100%. The fish
was raised on the experimental diet in plastic containers of 65 1 capacity for 60
days. Common carp fed on 100% sewage sludge failed to indicate appreciable
growth. However, partial replacement (50%) was favourable and resulted in high
growth (4.58 g). Fish reared with 50% sewage sludge supplemented diet also
attained high (9.12%) protein level (wet weight basis) as compared to control
(9.05%) and other treatments. The bacterial load in the selected body tissues was
well below the safe levels prescribed by WHO for human consumption. The values
of total coliforms, faecal coliforms, E. coli and streptococci ranged between 0-7,
0-3, 0-1 and 0-3 MPN/g respectively in fish skin and muscles
