Owena Reservoir was constructed in 1966 primarily to supply water to Ondo, Akure, and Bolorunduro mostly during the dry
season. There is dearth of information on the zooplankton of Owena Reservoir. The aim of the study was to investigate the
zooplankton of the river and its reservoir in order to provide baseline information which can be utilized as a platform for impacts
assessment, planning and implementation of policies for monitoring and effective development. Monthly sampling was carried
out from June, 2007 to July; 2009.plankton net of 55μm mesh size was used for collection of plankton using APHA methods.
Ecological indices including Shannon weaver (H?) margalef (d) and Equitability (E) were used for biological assessment. Data
were analyzed using correlation coefficient and one way analysis of variance (ANOVA). The zooplankton community was
in both seasons followed by
, other abundant species include
Lepadella patella, Asplanchna brightwelli, Filinia oponienses
. The percentage composition by number of the
zooplankton decrease at Inflow, Reservoir and Outflow.zooplankton present are indicative of organic pollution in Owena river
and its reservoir.
