The present study has been carried out during the period from January till September 2014. Samples of Rotifera were collected monthly from 5 stations located inside Tigris River at Baghdad city. The maximum recorded density was 40000 Ind/m3 which observed in April at station 5, whereas the minimum density was 450 Ind/m3 at station 1 in January 2014. There were identified 87 species of Rotifera belonged to 29 genera.The results of relative abundance index showed that the species of Rotifera: Keratella quadrata, K. cochlearis, Philodina roseola and Polyarthra ssp. were more abundant in all chosen stations at Tigris River.
Author Keywords: Rotifera, Biodiversity and relative abundance index.

Abstract: (arabic)
اجريت الدراسة الحالية خلال الفترة من كانون الثاني ولغاية ايلول 2014 تم خلالها جمع عينات الدولابيات Rotifera بشكل شهري من خمس محطات من نهر دجلة في مدينة بغداد. بلغت اعلى كثافة للدولابيات 40000 فرد/م3 خلال شهر نيسان في المحطة 5 واقل كثافة لها 450 فرد/م3 في المحطة 1 خلال شهر كانون الثاني 2014. تم تشخيص 87 نوع من الدولابيات تنتمي ل29 جنس. اظهرت نتائج دليل الوفرة النسبية ان انواع الدولابيات: Keratella quadrata, Keratella cochlearis, Philodina roseola and Polyarthra ssp. الاكثر وفرة في كل محطات الدراسة المنتخبة في نهر دجلة.
