Qualitative and quantitative analyses of phyto- and zooplankton, and growth performance of Cyprinus carpio Linnaeusweredonein earthenvats receiving compost, Diammonium Phosphateand vermicompostas direct application fertilizerwereconducted. Significantdifferences were observedin the diversity and abundance of plankton in response to fertilization. The highest production offish was obtained in the vats treated with vermicompost (3,970.56 kg/ha/90 days), followed byDiammonium Phosphate (3080.45 kg/ha/90 days), compost(1,952.64 kglha/ 90 days) and the lowest in the control(385.92kg/ha/90days). Vermicompost might bea cost-effective fertilizer in carp culture, replacingthe expensivechemicalfertilizerDiammoniumPhosphate.
