Significant differences (P<0.001) were observed in the diversity and abundance of plankton in response to fertilization with MF, SP and VC. The different fertilizer and manure used can be graded in the following descending order: VC, MF and SP. The least concentration was accounted in control sets. The highest production of fish was obtained in vats treated with VC (4,000.00 kg.ha-1 90 day-1) followed by MF (3,100.00 kg. ha-1 90 day-1), SP (2,030.00 kg. ha-1 90 day-1) and the lowest in control (CO) sets (390.00 kg. ha-1 90 day-1). The highest yield of fish in vats applied with VC is attributed to its highest manorial value. Keywords : organic manure, vermicompost, mixed fertilizer, plankton, fish production
