Physico-Chemical Parameters and Plankton Community of Egbe Reservoir, Ekiti State, Nigeria

J.B. Edward and A.A.A. Ugwumba    

Abstract: The physico-chemical parameters and plankton of Egbe Reservoir were studied from September 2004 to October 2006. Mean temperature, pH, conductivity, alkalinity, TSS, TDS and DO, BOD were 28.7°C±0.9, 8.3±0.3, 831±172.5 μS cm-1, 165.4±18.3, 0.06±0.1, 0.4±0.6, 7.8±2.4 and 5.1±1.6 mg L-1, respectively. Mean nitrate, phosphate and sulphate were 15.6±8.6, 42.5±19.4 and 72.3±mg L-1, respectively. About 35 genera of phytoplankton and 12 genera of zooplankton were identified in the reservoir. Diatoms dominated the plankton community making up 27.2% of the total plankton abundance by number while the Rotifers dominated the zooplankton, contributing 12.6% of the total plankton abundance. Diatoms showed the highest diversity (d = 1.77, H = 2.51) and are most evenly distributed (J = 0.93) among the phytoplankton while the Rotifers also showed the highest diversity (d = 0.70, H = 1.69) and even distribution (J = 0.94) among the zooplankton. Pollution indicator phytoplankton observed included Microcystis, Anabaena, Synedra, Melosira, Euglena, Phacus and Lepocinclis.
