The sea water temperature Received in revised form: 20.07.2021 was determined as 21.56±6.33°C, 21.1±6.40°C and 20.87±6.35°C at 2, 4 and 6 m depths, respectively. Accepted: 25.07.2021 Salinity values varied between 36 and 38.19 PSU in the region. The highest chlorophyll-a value was Available online: 08.08.2021 determined as 8.95 µg l-1 in August at 2m depth and 1.65 µg l-1 as the lowest at 4 m depth in January. Keywords: Average values of total particulate matter amount were calculated as 4.41±1.86 mg l-1, 5.09±1.88 mg Flexopecten glaber l-1 and 5.47±1.89 mg l-1 at 2, 4 and 6m depth, respectively. Scallop spats with an average height of Smooth scallop 8.26±1.55 mm were measured at the beginning of the study. The heights of the smooth scallop spats, Growth which were placed at 2m, 4m and 6m depths in the study area, were 42.6±1.11 mm, 41.53±12.85 mm Culture and 41.57±1.64 mm and their weights were measured as 12.71±0.89 g, 12.85±0.53 g and 12.82±1.00 Specific growth rate Aegean Sea g, respectively.
