In order to study the diversity of the bivalves, in each cruise the Rishness, Evenness and Diversity indexes were calculated. After each cruise the diversity of the stations were compared to the others using Shannon-Wiever Index. Furthermore the physichal and chemical factors of the water in each cruise, such as salinity, temperature, pH and dissolved oxygen in different depths, were also comparatively studied. Diversity of the bivalves was found to be higher in July than in May and November. It seems that density and diversity of bivalves in the Chabahar Bay are influenced by environmental changes caused by the Indian Ocean southwest summer monsoon.
