| Abstract | ||
| The Rotifers community along Shatt Al-Arab River was investigated during four seasons of 2006. 49 species belonging to 27 genera recorded. The genus Brachiouns the highest number of species (7) following by Monostyla and Trichocerca 4 each constituted and Keratella (3) species.. In general Brachionus calyciflorus and Keraktella valga were most frequent and dominant species. Within the five investigated sites, Al- Karoon station was characterized by highest rotifers density(369 ind./l) and Abu Al-Khaseeb station showed the less density ( 230 ind. / l ). However, summer was the period of highest densities. Diversity Indices for the five studied stations were calculated, the value ranged between 1.43 – 1.61 for Shannon – Weaver index, 6.29 – 8.47 for richness index, and between 0.51 – 0.55 for uniformity index | ||
