Abstract
In this study, age and growth rates of swordfish Xiphias gladius, caught from north Aegean Sea with landings in Gökçeada Island by harpoon fishing, were determined between 24 March and 15 June 2015. A total of 300 swordfish specimens that ranged between 74 and 174 cm Lower jaw fork length (LJFL) were used in the analysis. The length–weight relationships were calculated as W = 5E-06L^3.188 (R^2 = 0.948). A total of 83 anal fin rays were used in the analyses. The age-classes ranged from 0 to 5 years, while the samples were dominated by the 2 years old. The von Bertalanffy growth curves were fitted to the length at age data and the estimated parameters of the equation were: L∞ = 218.3; k = 0.193 and t0 = -2.1031.
