dc.description.abstractStudies on some aspects of physic-chemical parameters, phytoplankton and zooplankton composition were carried out for a period of twelve months in Sabuwa reservoir. Five sampling stations were selected for the research using standard methods of experimental analysis. Water depth, temperature, pH, transparency and electrical conductivity, ranges between 40 – 502cm, 22oC – 29oC, 6.44 – 9.32, 22.5cm – 54cm, 11 - 85μmho-s respectively. Dissolved oxygen concentration, biochemical oxygen demand, nitrate-nitrogen, phosphate-phosphorus and alkalinity varied significantly between seasons (P<0.05). Four classes of phytoplankton belonging to Chlorophyta, Cyanophyta, Bacillariophyta and Dinophyta were observed during the study with Chlorophyta accounting for 41%, followed by Cyanophyta 34% then Bacillariophyta and Dinophyta. Phytoplanton exhibited significant seasonal and spatial variations. Four classes of zooplankton belonging to Rotifera (35.9%), Cladocera (28.6%), Copipoda (18.8%) and Protozoa (16.7%) were observed during the study. The zooplankton groups exhibited significant variation between seasons where (p<0.05). Three groups of macro-benthic invertebrates comprising of Molusca, Annelida, and Nematoda were observed to be present. Stations 2 and 3 were found to be most productive while stations 1, 4 and 5 are less productive. The seasonal variations observed in plankton and macro-benthic composition, abundance and distribution were mainly a reflection of physic-chemical changes associated with the reservoir and their respective responses by the biota.en_US
