Preliminary observations on the utilisation of pig-dung effluent for fish production
MetadataShow full item record
In developing Singapore where agricultural land is making way for urbanisation and industrialisation, carp culture is being looked upon from a new perspective. It is obvious that the wanton discharge of animal waste will eventually result in polluted streams, reservoirs and coastal waters. In view of the above, preliminary investigations were carried out to evaluate the use of cess-pit effluent of pig dung for carp production. Initial results indicate that the carp pond can serve as a buffer zone where organic wastes can be cheaply and profitably removed, thereby minimising the subsequent pollution of our inland and coastal waters. However, further investigations are necessary to substantiate the use of carp ponds not only for fish production but also to serve as a reservoir for the biological reduction of organic pollutants.
