Abstract

Forty-six individuals of Carcharodon carcharias were either recorded or sighted in Turkey's waters during a period from February 1881 to 28 September 2011. Total lengths (TLs) of the recorded great white sharks ranged from 85 cm TL to ~800 cm TL, and mass ranged between 12 kg and ~4500 kg. Three non-fatal shark attacks on boats of tuna hand-liners were also recorded. A North Aegean Sea specimen (85 cm TL; sp No. 45; Table 1) caught by a coastal trammel netter in Edremit Bay on July 6, 2011, is possibly the smallest neonate white shark from Mediterranean waters to date. Due to intensification of tuna fishing and the resulting decline or extinction of tuna stocks, C. carcharias is now apparently extinct from marmaric and bosphoric waters. Capture of 6 neonate great white sharks between 2008 and 2011, in the same period of the year (from late June to early July), in the waters of Edremit Bay (northern Aegean Sea, Turkey) suggests the possibility of a breeding ground in the region. The growing tuna farm industry offers a new possibility for encounters between humans and great white sharks off the Turkish coast.
