Abstract

Okerenkoko Estuary (OE - 62.79 Km) plays very crucial roles to its surrounding communities. But in recent times, its fauna abundance has been impaired due to anthropogenic activities. Studies on OE fauna abundance are limited. Hence, this study was under taken to investigate OE Zooplankton community abundance. The OE was spatially stratified into five stations (Z 1 – Z 5) based on proximity to major anthropogenic sources. In each station, three sampling points were randomly selected.Water and zooplankton samples were collected monthly for 12 months in wet (March – October) and dry (November – February) Seasons according to standard methods. Water samples were analysed for Temperature .........................................................................................................................................................................................
