İzmir Körfezi’nden (Kuzey Ege Denizi) Akdeniz Kılıcı’nın, Tetrapturus belone Rafinesque, 1810 (Istiophoridae) İlave Kaydı

Öz

Tetrapturus belone Akdeniz'e endemik bir türdür ve Akdeniz’in orta kısımlarda daha yaygındır. Levant'ta ise çok nadir kabul edilir. 20 Ekim 2020 tarihinde, Urla, Karantina Adası kıyılarında, 11 m derinlikte, 176 cm (26 kg) bir Tetrapturus belone örneği fanyalı ağla yakalanmıştır. Dokuz yıl önce, bu epipelajik balık, 2011 yılında İzmir Körfezi'nin sığ sularına girmişti. Şaşırtıcı bir şekilde 158 cm alt çene çatal boyu (LJFL)'na sahip bu balık, aynı alanda ve derinlikte ortaya çıkmış ve ayrıca bir fanyalı ağla yakalanmıştı. Bu ihtiyolojik not, Akdeniz kılıcının Urla'nın (İzmir Körfezi) belirli bir kıyı bölgesinde küçük ölçekli balıkçılıktan tesadüfi olarak yeni bir bulunuşunu sunmaktadır.

Tetrapturus belone is endemic to the Mediterranean and it is more common in central parts. It is considered very rare in the Levant. On 20 October 2020, a specimen of Tetrapturus belone with 176 cm Lower Jaw Fork Length (LJFL) and weighing 26 kg was captured by a trammel net from the coast of Karantina Island, Urla at a depth of 11 m. This is the second record of the epipelagic T. belone entering the shallow waters of İzmir Bay, nine years after its first record in the same area. This ichthyologic note presents a new occurrence of the Mediterranean spearfish as an incidental catch from the small scale fishery in a certain coastal area of Urla, Izmir Bay.
