The biological indicators studies of zooplankton in the Tigris River at the city of Baghdad

The study of biological indicators for zooplanktonis important factors in environmental studies to show the extent of the surrounding organisms, distribution and deployment environment affected. Zooplankton samples were collected from three stations on the Tigris River in the city of Baghdad using zooplankton net, specimens preserved and laboratory-diagnosed using Internationally recognized classifications. Results show through the presence of relatively high abundance of zooplankton in the three stations and not affected by the city in addition to the species abundance is the other index gave few differences between stations, a lack of environmental pressures on these organisms in the station directory. Also, Shannon-Weiner diversity Indexpointer gave no significant differences between the study stations
