Abstract :
Gastropod assemblages were investigated along intertidal rocky shore in the Qeshm Island in the northern
Persian Gulf. Monthly sampling was undertaken from May 2007 to April 2008. Environmental factors
were also measured in each site. A total of 28 gastropod taxa belonging to 15 families were identified and
Cerithiidae was the most abundant family and Cerithium caeruleum was the most abundant species
(34.77%). Muricidae with 5 species were the most diverse group followed by Cerithiidae and Cypraeidae
each with 4 species. Kruskal-Wallis test yielded no significant differences in gastropod assemblages
among months and also different seasons (P > 0.05). The analysis of SIMPER showed that spring and
autumn had the most dissimilarity among seasons and Clypeomorus bifasciatus was the species of
gastropods contributing most to the dissimilarities among seasons (37.54%). December showed the
highest value of Shanon-Wiener (2.15) and Simpson (0.85) indices. Lack of significant temporal variation
in gastropod assemblages during sampling months suggested that intensity of sampling in future studies
could be reduced to seasonal intervals in similar environmental conditions. Where intertidal surveys are
restricted by time,and resources such as, personnel and finance.
