Summary
<p>European oyster (Ostrea edulis L. 1758) in Uzbek-Urla (Izmir) in this study examined individuals placed in Augmentation systems to determine the growth and survival rates of their spats. Temperature, salinity, total particulate matter (TPM) (particulate organic-POM and particulate inorganic-PIM) and chlorophyll-a values were recorded from water parameters throughout the year. The highest in total particulate matter was found at 34.62 mg/l in June. In June, the ratio of inorganic matter in particulate matter was 77.61% and the ratio of organic matter was 22.39%. Mean length of Oyster larvae taken into Augmentation Systems reached from 26.39±4.00 mm at the beginning of the study to 60.84 ±10.71 mm at the end of the study. A significant negative correlation was found between survival rate with temperature and PIM (r2 = -0.654, r2 = - 0.644, respectively) (p <0.05).The survival rate of oysters was found to be 61.9%. The results of the survival and growth rate obtained indicate that this region may be suitable for the cultivation of Ostrea edulis. </p>
