This study was carried out in order to reveal the Bivalvia fauna of the mediolittoral and upper
infralittoral zones of the Dardanelles, between May and August 2019 in a total of 16 stations, 8 on the
Gallipoli Peninsula and 8 on the Anatolian coast. For sampling in hard bottom stations was used with
20 x 20 cm quadrat, for soft bottom was used a plastic core of 7 x 20 cm dimensions and the distance
of all sampling areas to the coastline was measured with a tape measure. Coordinates of each station
with GPS and physico-chemical properties of surface water such as dissolved oxygen, conductivity,
salinite, temperature, TDS and ORP were measured with the YSI Multi-probe system in situ. All the
samples taken were sorted through sieves with 0.5 mm mesh size, and a total of 14 species (Donacilla
cornea, Hiatella arctica, Mytilus galloprovincialis, Mytilaster lineatus, Musculus costulatus,
Arcuatula senhousia, Polititapes aureus, Ruditapes phillippinarum, Irus irus, Chamelea gallina,
Spisula subtruncata, Papillicardium papillosum, Glans trapezia and Lucinella divaricata), 9 of which
were alive were obtained. Mytilus galloprovincialis is the species has the highest frequency and
dominance among a total of 792.736 individuals. The highest number of species (6) were obtained
from the upper infralittoral zone of the Kepez Station, the highest individuals (352.987 individuals.m2
) were obtained from the mediolittoral zone in the station of Gelibolu. In the study, it has been
revealed that the locations of the stations in the Dardanelles, bottom structure, differences of zone and
the distance of the sampling areas to the coastline do not have a statistically significant effect on the
distribution of bivalve species.
