Özet: Data on age, growth, reproduction, mortality and exploitation were examined for common sole collected in İskenderun Bay from March 2000 to February 2001. The examined individuals were aged between 1 and 8 years. Total length ranged from 8.8 to 28.2 cm. The length-weight relationships for males (a = 0.0117, b = 2.998) and females (a = 0.0091, b = 3.077) showed no significant difference from isometric growth. Von Bertalanffy growth parameters were L\infty = 26.03 cm, k = 0.221 year-1, to = -1.31 for males and L\infty = 29.95 cm, k = 0.181 year-1, to = -1.55 for females. The reproductive activity of the common sole in the Bay of İskenderun took place between April and May, peaking in April. First maturity lengths (Lm) were 14.8 cm for males and 15.2 cm for females. Total (Z), natural (M) and fishing (F) mortalities were Z = 1.32 year-1, M = 0.50 year-1 and F = 0.82 year-1, respectively. The exploitation ratio E = 0.62 indicates that the population is being heavily exploited.
