Protection of biodiversity in all aspects is important in management of aquatic environment. In relation with this case, there are many problems in Iran. Recently, the same studies are growing, but still there is a more-in-depth researches needed. This study was carried out during 2001–2002 for determining of composition and frequency of macrobenthoses, identification and diversity of fishes in different seasons in Gomishan Canal that is located in south-east of Caspian Sea. Analysis of samples mostly determined 3 groups, Mollusca, Annelidae, and Arthropoda that their frequencies changed in different months. The most frequency of group were Mollusca (88.25 %), Annelidae (9.94 %) and Arthropoda (1.80 %) of benthoses.

Of fishes, 8 genus belonging to 7 families include of: Carassius auratus, Gambusia holbrooki, Atherina boyeri, Neogobius spp., Liza sp. (L. auratus and L. saliens), Gasterosteus aculeatus, Clupeonella grimmi, Rutilus rutilus were sampled. The only available data comes from Kiabi et al. (1999), who reported 20 species belonging to 8 families in the Gomishan Wetland. Our results are not in agreement with their findings. The reason for these differences could be that our study area was the canal. It should be mentioned, fishing activities in the wetland restricted to illegal subsistence fishery.
