Özet
The present work was aimed at determining the growth parameters of the garfish, Belone belone, a commercially important pelagic fish species in Izmir Bay (Aegean Sea). A total of 347 garfish specimens was collected during the period January-December 1997 from purse-seine boats operating in Izmir Bay. Fork length and total weight of the specimens ranged from 26.0 to 54.5 cm and from 16.51 to 281.73 g, respectively. Maximum age group determined was V for females and IV for males. Female : male ratio was 1 : 0.45. Most specimens belonged to age group II. The von Bertalanffy growth equations for length and weight were
