Abstract :The taxonomic composition of diatom flora of the Balikhli River insert ignore into journalissuearticles values(Balikhli Chay);, Northwest Iran, was studied from October 2013 through September 2014. In total 109 taxa belonging to 50 genera were identified. Nitzschia insert ignore into journalissuearticles values(18 spp.);, Navicula insert ignore into journalissuearticles values(9 spp.);, and Gomphonema insert ignore into journalissuearticles values(7 spp.); were the most abundant genera. Twenty-five diatom species were found in more than half of the samples; among them, Nitzschia inconspicua , Planothidium lanceolatum , Amphora pediculus , Navicula trivialis , Gomphonema olivaceum , Nitzschia palea , and Rhoicosphenia abbreviata were the most abundant taxa, which are characteristic for alkaline and eutrophic waters. The centric diatoms constituted only 4.54% of all identified taxa. In this study 20 taxa were recorded for the first time for the aquatic ecosystems of Iran.
