Mollusc Fauna of Kemer Bay (sea of Marmara)

In the present study, mollusc species distributed in the Kemer Bay (Sea of Marmara) were determined seasonally (November, February, May, and August) in the years 2010 and 2011. The benthic samples were collected from different biotopes in 16 stations at depth ranging between 0.2 and 5 m by using a quadrate sampling gear. As a result of the evaluation of collected benthic materials, a total of 66 mollusc species belonging to 3 classes (Polyplacophora, Gastropoda, and Bivalvia) were identified. When the number of species and individuals are compared based on the seasons, maximum number of species (46 species) and individuals (168825 ind. m(-2)) were counted in autumn and spring, respectively. Mytilus galloprovincialis (Lamarck, 1819) and Mytilaster lineatus (Gmelin, 1791) were the most abundant species in all the seasons. Whereas, Bittium reticulatum (da Costa, 1778), Rissoa membranacea (Montagu, 1803), and Tricolia pullus pullus (Linnaeus, 1758) were characterized as species having the highest frequency index values in all seasons.
