D. sargus had a range of total length and weight from 14.3 cm to 36.7 cm and from 50.5 g to 836.5 g, respectively. The length-weight relationships (LWRs) were calculated as W=0.02368*L-2.881 for females, W = 0.01847*L-2.959 for males and W = 0.01989*TL2.936 for both sexes. Using data from fish scales, the maximum age was determined to be 11 years. von Bertalanffy growth parameters have been calculated as follows L-infinity=39.01 cm TL, K=0.13 year(-1), and t(0)= -2.58 year for both sexes combined. Total (T), natural (N) and fishing (F) mortalities were defined as Z: 0.83 year-1, M: 0.33 year(-1) and F: 0.50 year(-1) for both sexes combined. The exploitation rate (E) was calculated as 0.70, 0.44 and 0.60 for females, males and combined, respectively.eninfo:eu-repo/semantics/openAccessAgegrowthmortalitylength-weight relationshipwhite seabreamAegean SeaArticle411303610.12714/egejfas.41.1.05N/AWOS:0012551332000051229357
