İskenderun Körfezi'nde (Doğu Akdeniz Bölgesi) Ergin Dişi Uçurtma Yüzgeçli Köpekbalığı, Dalatias licha'nın (Bonnaterre, 1788) Varlığı

Abstract

Türkiye’nin Çevlik (Doğu Akdeniz) sahillerinden 11 Haziran 2016 tarihinde 118 cm toplam boyunda uçurtma yüzgeçli köpek balığı, Dalatias licha'nın tek bir dişi bireyi ticari troll ağı ile 40 m derinlikten avlanmıştır. Sunulan bu makale yetişkin dişi bir birey D. licha’nın Türkiye’nin Akdeniz sahillerinden ilk teyididir. Örneğin ölçümleri yapılarak bu türün Akdeniz’deki coğrafik dağılımı belgelenmiştir.

Occurrence of adult female Kitefin shark Dalatias licha (Bonnaterre, 1788) in Iskenderun Bay (Eastern Mediterranean, Turkey)

Abstract

A single female specimen of the Kitefin shark Dalatias licha (Dalatiidae), 118 cm in total length (TL), was caught by a commercial trammel net at a depth of 40 m on 11th June 2016 off the Çevlik coast (Eastern Mediterranean), Turkey. The present paper was the first confirmation of an adult female specimen of D. licha from the Mediterranean coast of Turkey. Measurements of the specimen were given and the geographical distribution of the species in the Mediterranean was documented.The Kitefin shark is a deep-water species, benthic to mesopelagic species, and mainly distributed in the western Atlantic, western Indian Ocean, and Pacific Ocean (Compagno 1984, Last and Stevens 1994). However, the range of this species in the Mediterranean appears to be confined to the western and central basins of the Mediterranean (Baino et al 2001). The occurrence of the species in eastern Mediterranean is highly rare and the first report in the area was documented by Akşıray (1987). Then, Papaconstantinou (1988) reported the presence of the kitefin shark in the Aegean Greek waters. Seven years later, Meriç (1995) also reported the species off the Turkish coasts of eastern Mediterranean. Kabasakal and Kabasakal (2002) indicated the presence of the species in northeastern Aegean Sea with the record of five young kitefin shark specimens during breeding season off the northern coast of Gokçeada in 1999. Further reports of the species have been documented several times off the western Mediterranean (Bottaro et al 2003, Bottaro et al 2005, Capape et al 2008) and Levantine coasts (Golani 2004, Saad et al 2004) up to now.
