dc.description.abstractThis study evaluated the Physico-Chemical parameters and plankton composition of Wawan-Rafi Lake in Kazaure, Nigeria. Monthly variation and composition of Physico-Chemical and biological (plankton) parameters of Wawan-rafi Lake were studied for a period of six months (July – December 2013). Result showed monthly variations of Physico-Chemical parameters. Means of monthly values of pH ranges between 6.00-7.12, temperature ranged between 18 – 240C, and electrical conductivity was between 273.33μs/cm – 540.00μs/cm . Dissolve oxygen (DO), Dissolved solid (DS) and Biological oxygen demand (BOD) Means of monthly values ranges between 3.53±0.03 mg/l – 6.00±0.31mg/l, 103.67±5.78mg/l - 131.00±12.01mg/l, and 5.10±0.10mg/l – 6.83±0.20mg/l respectively. While Suspended Solid (SS), sulphate, phosphate, nitrate and chemical oxygen demand (COD) their Means of monthly values ranges between 2.33±1.95mg/l – 96.00±8.96mg/l, 5.94±3.60mg/l – 14.98±0.09mg/l, 8.33±2.98mg/l – 16.73±0.88mg/l,8.97±0.63mg/l-10.37±0.38mg/l and 1.50±1.01mg/l–6.00±1.16mg/l respectively . Four Phytoplankton phyla were recorded, they were dominated by Chlorophyta then Cyanophyta followed by Euglenophyta and Bacillariophyta. The Zooplankton of the lake were made up of Protozoa, Rotifers and Cladocera. Correlation matrix showed that there were significant correlation between Phytoplankton, Zooplankton and Physico-Chemical parameters. The composition of plankton of Wawan-Rafi Lake were affected by seasonal variations and fluctuation of Physico-Chemical parameters.en_US
