Abstract

A sewage effluent and different concentrations of digested sludge ranging from 0 to 0.8% in tap water were used for raising carp. The highest growth rate of carp occurred in the 0.2% sludge, followed by the sewage effluent and 0%, 0.4%, 0.6% and 0.8% media. Similar results were obtained from measurements of the dry weights and protein contents of the carp at the end of the experiment.
The higher metal contents in the 0.4%, 0.6% and 0.8% media possibly accounted for the death and unhealthy appearance of fish reared in these media.
It is urged that the amount of sludge be estimated accurately before its disposal into fish ponds. The uptake of heavy metals and other persistent materials by fish should also be investigated. Copyright © 1977 Published by Elsevier Ltd.
