The goal of this
study was to determine the community structure belonging to the Prosobranchia
(Gastropoda, Mollusca) in soft bottoms of the Çanakkale Strait coastal waters
(0-5 m). Benthos samples were collected seasonally using a 30x30 quadrate
operated by a SCUBA diver between July 2008 and April 2009. Samplings were
carried out at 3 transect depths of 8 different locations of the Çanakkale
Strait. A total of 4472 specimens of Prosobranchs were recorded. Rissoa
splendida Eichwald, 1830 was the numerically dominant species (Di % = 20.57).
Kilitbahir location had the highest number of individuals (1069), while the
Lapseki location had the lowest number (157). According to Spearman’s rank
correlation, the highest positive correlation (rs = 0.75) was between salinity
and species number. Conversely, the lowest correlation (rs = 0.51) was found
between pH and species number. Bray-Curtis similarity index showed that summer
and winter periods were very similar (88.65 %). Çanakkale and the Kilya inlet
points had the highest similarity (70.87 %).
