Limnological features of Ikere Gorge Reservoir, Iseyin southwestern Nigeria: Plankton composition and abundance
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2012, Vol 2, Issue 6
Abstract
A study of plankton composition of Ikere gorge reservoir Iseyin, South Western Nigeria was conducted from July to December 2007. The plankton taxa encountered were- Protozoa (10), Rotifera (9), Copepoda (4) Cladocera (4), Ostracoda (1), Insecta (1), Arachnida (1), Cyanophyceae (7), Bacillariophyceae (8), Chlorophyceae (22) and Euglenophyceae (1). Chlorophyceae were more abundant among phytoplankton throughout the study period with highest species richness index (2.4) while Copepods dominated the zooplankton fauna. No mark spatial variation was observed except for Bacillariophyceae. Rotifera, Ostracoda, Cyanophyceae, Bacillariophyceae and Chlorophyceae are higher during the raining season months than dry season months but only Chlorophyceae showed significant difference. Some indicators of pollution, Microcystis, Anabaena, and Oscillatoria, were encountered. The high relative abundance of Chlorophyceae and Copepoda is an indication that the reservoir will support fish production.
