Abstract:

Between 1 July 2008 and 14 April 2018, five young-of-the-year (YOY) (TL range 85-175 cm) and six juvenile (TL range 180-300 cm) white sharks (Carcharodon carcharias) were caught off the Turkish coast of the Aegean Sea. The mean length + standard deviation of YOY and juvenile white sharks were 138.1+34 cm and 206.6+46 cm, respectively. The YOY white sharks were caught only in Edremit Bay and juveniles were captured in several localities outside of the mentioned region. Based on the findings of previous studies, it is suggested that Edremit Bay may serve as a nursery ground for C. carcharias in the northern Aegean Sea and the surrounding insular marine area outside of the bay waters, may serve as a growing and feeding ground for juveniles until maturity. The white shark population in the Mediterranean may be considered at greater risk of local extirpations than previously thought, and effective management of Edremit Bay as a nursery ground is crucial regarding the overall survival of white sharks in the Mediterranean.
