Popis: In this study, the growth parameters of the bluefish, Pomatomus saltatrix (Linnaeus, 1766), were studied in Gallipoli Peninsula and Dardanelles (northeastern Mediterranean, Turkey) between November 2008 and October 2009. The length-weight relationship was calculated as W=0.0082TL3.02 for females, W=0.0081TL3.03 for males and W=0.0081TL3.03 for all samples. Growth parameters of the populations were L∞= 86.8 cm, k=0.15 year-1, t0=-1.40 for females; L∞=89.1 cm, k=0.16 year-1, t0=-1.46 for males and L∞=88.3 cm, k=0.15 year-1, t0=-1.43 for all samples. Total mortality rate (Z), natural mortality rate (M), fishing mortality rate (F) and exploitation rate (E) of the bluefish were 0.90 year-1, 0.21 year-1, 0.69 year-1 and 0.76 year-1, respectively
