Abstract: Studying plankton community and determining the trends in river pollution are of great value and importance. In the present work, plankton and aquatic insect community were evaluated in 10 sites along the Sarbaz River in southeastern Iran. Among the species identified, Navicula has the highest incidence with five species. The highest frequency and density belongs to the ciliates group. Results indicate that the studied environment has a poor planktonic diversity and density. Results suggested that a decrease in plankton communities could be one of the factors influencing reductions in mugger crocodile (C. palustris) hatchling survival. Moreover, it was found that dominant populations of aquatic insects are susceptible to organic pollutants with tolerating levels of 0 to 4 from Diptera, Ephemeroptera, Trichoptera, Ephemerehidae, Hemiptera, Odonata orders. Moreover, an increase is noted in the Family Biotic Index (FBI) in downstream sites, suggesting a decrease in water quality compared with other sites.
