Fish species diversity of the coastal areas in Gomishan wetland

During the study, which was conducted to determine fish species diversity in coastal areas of the Gomishan wetland on the basis of twice per season from autumn 2006 to summer 2007, 13555 specimens belonging to 15 species and 8 families were caught. Total diversity and frequency of species and frequency of each species were different among the seasons. Atherina boyeri was dominant in spring, summer and winter, Gambusia holrooki in autumn. Alburnus albulnus had the lowest quantitative abundance in the study area. Out of six Gobiid fishes, Neogobius fluviatilis and Bentophilus stellatus showed the highest and the lowest abundance respectively. In the coastal areas of the Gomishan wetland, the highest Shanon and diversity indices were observed in winter, the highest richness index in spring and the highest evenness index in winter.
