| Abstract | ||
| Samples of zooplankton were collected seasonally from seven stations in the marshes South of Iraq. For the period from December 2003 to November 2004, by plankton net 120 micron mish-size. Water temperature, salinity and pH were recorded at each station. The population density of zooplankton ranged between 52 ind./ m3 at station 5 (Al-Barga region) during Autumn, to 3309 ind /m3 at station 2 (Al-Turaba region) during Spring 2004. Crustacea was the dominated group in all stations because the Copepoda was very abundant and its comprised 62.4%, 67%, 89.9%, 62.5%, 31.5%, 49.9%, and 64.9%, in stations (1,2,3,4,5,6,7)respectively. The density of zooplankton is governed inversely by water temperature and to lesser extent by salinity. A total of 18 species of Cladocera belonging to 12 genera were identified in the area, 5 species are new records to the Iraqi marshes. | ||
