The sea water temperature was determined as 21.56 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">6.33°C, 21.1 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">6.40°C and 20.87 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">6.35°C at 2, 4 and 6 m depths, respectively. Salinity values varied between 36 and 38.19 PSU in the region. The highest chlorophyll- <i>a </i> value was determined as 8.95  </span> <span style="font-size:.9em;">µ </span> <span style="font-size:14px;">g l <sup>-1 </sup> in August at 2 m depth and 1.65  </span>µ <span style="font-size:14px;">g l <sup>-1 </sup> as the lowest at 4 m depth in January. Average values of total particulate matter amount were calculated as 4.41 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">1.86 mg l <sup>-1 </sup>, 5.09 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">1.88 mg l <sup>-1 </sup> and 5.47 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">1.89 mg l <sup>-1 </sup> at 2, 4 and 6 m depth, respectively. Scallop spats with an average height of 8.26 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">1.55 mm were measured at the beginning of the study. The heights of the smooth scallop spats, which were placed at 2 m, 4 m and 6 m depths in the study area, were 42.6 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">1.11 mm, 41.53 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">12.85 mm and 41.57 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">1.64 mm and their weights were measured as 12.71 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">0.89 g, 12.85 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">0.53 g and 12.82 </span> <span style="font-size:.9em;">± </span> <span style="font-size:14px;">1.00 g, respectively. While the survival rate was 53% placed at 2 m depth in the study area, the lowest survival rate was found as 37% for the spats grown at 6m depth. The result showed that the mean values of height at the surface depth (2 m) were more significant than those at the other depths (4 m and 6 m). However, there were no statistically significant differences between the depths and specific growth rate (SGR) for height and weight (p>0.05). But SGRh and SGRw values at each depth showed statistically significant differences between months (p<0.05). </span> </div>}, number={3}, publisher={Adem Yavuz SÖNMEZ}
