Abstract :This study was conducted at Cardak Lagoon of Dardanelles between August 2009 and March 2010. The average initial and final length of the Mediterranean mussel insert ignore into journalissuearticles values(Mytilus galloprovincialis Lamarck,1819); from different depths insert ignore into journalissuearticles values(0.5 m, 5 m, 10 m); were measured as 9.75± 0.81 mm - 41.21±3.42 mm, 9.76±0.87 mm - 39.64±2.90 mm, 9.95±0.75 mm - 38.13±2.70 mm and 0.11±0.03 g - 6.56±1.82 g, 0.11±0.03 g - 5.83±1.23 g, 0.11±0.02 g - 4.39±1.00 g, respectively. On the growth of mussels, monthx depth interaction insert ignore into journalissuearticles values(P = 0.221); and depth insert ignore into journalissuearticles values(P = 0.078); did not show a significant effect, but months were found to be effective insert ignore into journalissuearticles values(P = 0.00);. The survival rates of the mussels at 0.5 m, 5 m, 10 m depth were determined as 87%, 87% and 76%, respectively. The difference of the survival rates of the mussels with respect to different months was significant insert ignore into journalissuearticles values(P = 0.011);. Nevertheless, the depth had no effect upon the mussel survival rate insert ignore into journalissuearticles values(P = 0.091);. It was confirmed that especially the particulate organic matter insert ignore into journalissuearticles values(POM); detected in water as well as the particulate inorganic matter insert ignore into journalissuearticles values(PIM); played a significant role in addition to the slight role that the salinity had on the growth performance of the mussels.
