Abstract This study was carried out during 2001-2002  period to determine the composition and frequency of macrobenthoses. Identification and diversity of fishes in different seasons in Gomishan Canal located in south-east of Caspian Sea were done. The analysis of benthos samples showed three main groups of  Mollusca, Annelidae and Arthropoda whit changed frequency in different months of the year. The order of the frequency from the highest to the lowest was as follow: Mollusca (Mean: 88.25%), Annelidae (Mean: 9.94%), and Arthropoda (Mean: 1.8%). Eight genus and seven families included in the sample were Carassius auratus, Gambusia holbrooki, Atherina boyeri, Neogobius spp, Liza sp.
