During 2009-2010 years epifaunal materials were
collected seasonally with a beam trawl from seven fixed stations in
infralittoral of Gulf of Izmir to study spatiotemporal distribution of
megabenthic fauna and their ecology. A total 153 megafaunal species were identified belonging to
nine phyla, comprised mostly by 54 molluscans, 43 chordates (mostly fish), 20
arthropods, and 18 to echinoderms. Nine alien species were found. Four species
(two fish species, one gastropod and one Asteroidea species) were constant
species and 16 species were common species in the study area. Lesueurigobius
friesii, Buglossidium luteum, Turritellinella tricarinata and Astropecten irregularis were the most
frequently occurred, and Lesueurigobius friesii, Varicorbula gibba, Anomia
ephippium, Turritellinella tricarinata and Dentalium sp
were the most abundantly occurred species. Excluding the evenness index
faunistic characteristics were tended to increase by seafloor depth. Seasonal density
(abundance and biomass) was minima in April and maxima in February, followed by
November being 2-fold higher in abundance than July. Faunal assemblages were
oriented with sectors of the gulf and habitat type along the depth gradients. Buglossidium
luteum overspread the gulfs excluding the inner gulf. Varicorbula gibba and Fulvia fragilis, a pollution indicator
predominated the inner gulf. Hydrographical parameters and bottom depth were
associated to dictate faunal assemblages with difference among the sectors and
habitats.
