Saccostrea cucullata is one of the widely spread oysters in south coasts of Iran. This study was conducted on 80 specimens of S. cucullata from coastal areas of the Laft port in the Qeshm Island in order to determine the relationships between growth factors and age. The population was divided into five age groups. The 2 year-old and 5 year-old oysters had the highest and lowest number of individuals in the population, respectively. The lowest and highest values of the length, width, height, shell thickness and wet soft tissue weight of S. cucullata were 20-70 mm, 10-50 mm, 3.50-26.50 mm, 1.00-5.90 mm , 0.75-7.68 g, respectively. After testing the normality of the data, their relationships were investigated using correlation and regression. A weak but positive correlation with a significant linear relationship was found between age and growth factors. However, because of the weakness of the correlation, no precise criteria can be found for determination of age based on growth factors.
