Comparative Studv on zooplankton Communitv Collected from Different irrigated FishFarms andMass Culture of Their Dominant Species

Abstract

This study was carried out to examine the impact of fresh, drainage, and sewage wastewater on zooplankton community. The results showed that appearance of three orders Cladocera (Ciadocera play major role information of zooplankton in the studied groups, the Cladoceran community is consists of mainly 11 species (four dominant species), Rotifera (Rotifera is the most abundant order in all groups. A total of 13 Rotiferan species were recorded) and Copepoda (There are three cyclopoid copepods species and two stages of copepod larvae). The highest density of zooplankton species was recorded in summer followed by autumn at sewage wastewater, drainage water then fresh water ponds.
