Gopalakrishnan, V and Srinath, EG (1963) Some experimental observations on the use of activated sludge as fertilizer for fish culture. In: Proceedings of the Indian Academy of Sciences - Section B, 57 (6). pp. 379-388.Full text not available from this repository. (Request a copy)
Experiments were conducted in cement cisterns to find out the effect of adding different dosages of activated sludge on fish growth and plankton production. Three dosages of sludge,viz., 62·5 gm., 125 gm. and 250 gm. per 240 litres of water were used. Fingerlings ofCyprinus carpio, Cirrhina mrigala andCatla catla responded positively,C. mrigala showing maximum growth. The results indicate that the sludge has a direct influence on increasing growth of fish and production of plankton due to the release of nutrients into the water. The increase in plankton content stops after about 30 days. When greater quantities of sludge were added in the cisterns, fish mortality took place.
