Abstract :

Background and Objective: Due to importance of Sarbaz River in the Sistan and baloochestan province, study about environmental status of this river especially plankton community have so valuable and importance.So, this research was conducted to study plankton community of Sarbaz River. Method: Sampling was carried out monthly in the ten sampling sites (Kajdar, Bandan, Hit, Firooz abad, Pole jakigoor, Ab nemaye Sade pishin, Pole kahirborz, Shir govaz, Jor) through Sarbaz River. The collected samples were fixed in 10% formalin and brought to the laboratory for plankton analysis Findings: Generally, ten species of phytoplankton (Bacillarphyceae) were identified in the all sampling sites. The Navicula with five species was more frequent than other phytoplankton species. Three groups of zooplankton including crustacean, rotifer and ciliates were identified in the all sampling sites. We have identified two groups of crustacean: Cyclops and daphnia. The frequent species among zooplankton were ciliates. This species have found in the all sapling sites and times. We have found negative relationship between diversity and frequency of crustacean. Crustacean with higher diversity have lower frequency. Conclusion: Studying plankton community in the Sarbaz river have shown that this environment have very low plankton diversity and frequency.
