Abstract

The incorporation of 10 or 40% of activated sludge improved the growth rates of common carp, Cyprinus carpio, by comparison with those receiving a commercial fish feed (Tubifex worms) alone. The incorporation of 70% or 85% sludge, however, yielded very poor growth rates.
The visceral organs of fish receiving 70 or 85% sludge contained 2 × zinc (Zn), 2.5 × copper (Cu) and 1.4 × manganese (Mn) of the control group. Copyright © 1981 Published by Elsevier Ireland Ltd.
