Plankton studies in the downstream areas of Shahid Shahcheraghi Dam and the edge of Cheshme Ali Damghan spring in 2016, plankton studies were considered as basic studies for the feasibility of aquaculture in this lake. For phytoplankton sampling from each station, one liter of water without passing through the zooplankton net, and for zooplankton sampling, 30 liters of water was filtered by a manual zooplankton net (Apstein-Net) with a 55 micron mesh. Finally, the samples were fixed with 4% formalin and transported to the laboratory for study In phytoplankton study, a total of 6 Phyla and 36 genera were identified, most of the observed genera belong to the Ochrophyta. the most important genera of this Phylum were Synedra, Diatoma and Nitzschia. Which have 91% of the annual abundance of phytoplankton. The studies showed that this river is limited to fixed and sticky groups of protozoa and rotifera in terms of zooplankton. In zooplankton studies, 8 phyla and 34 genera were identified, with the highest diversity and abundance related to protozoa with Amoebazoa, Cercozoa and Ciliophora Phyla, then Rotifera with dominant genera Synchaeta ,Polyarthra and Cephalodella, which have close annual average abundance. The results obtained from the plankton survey in this project showed that these areas have the abundance and diversity of plankton suitable for aquaculture.
