    • Abstract


      Survival, growth and reproduction ofCyprinus carpio were studied in ponds treated with mahua oil cake and single superphosphate. The results indicated that single superphosphate (500 kg/ha) compensated for the deleterious effects of mahua oil cake (2,000 kg/ha) on survival, growth and reproduction of fish. Better fecundity-weight relationship of fish and bottom organisms were evident at the same input levels. In order to maintain ammonia concentration in ponds below the toxic threshold, application of single superphosphate seems to be essential. For better fish culture management, use of mahua oil cake in high amount or its frequent addition should be avoided.
