Gökçeada çevresinde zıpkın ile yakalanan kılıç balıklarının (Xiphias gladius) yaş ve büyüme özellikleri

Öz

Bu çalışmada Kuzey Ege Denizinde 24 Mart – 15 Haziran 2015 tarihleri arasında zıpkın ile yakalanan ve Gökçeada’da karaya çıkarılan kılıç balığı, Xiphias gladius bireylerinin yaş ve büyüme özellikleri belirlenmiştir. Alt çene çatal boyları (LJFL) 70 ile 174 cm ve ağırlıkları 4 – 69 kg arasında olan toplam 300 adet kılıç balığı analizlerde kullanılmıştır. Boy – ağırlık ilişkisi W = 5E-06L3,188 (R2 = 0,948) olarak hesaplanmıştır. Toplam 83 adet bireyden anal yüzgeç ışınları kullanılarak yaş tayinleri gerçekleştirilmiştir. Yapılan yaş tayinleri sonucunda, kılıç balıklarının 0 - 5 yaş arasında oldukları ve en fazla bireyin 2 yaşında olduğu tespit edilmiştir. Von Bertalanffy büyüme denklemi L∞ = 218,3; k = 0,193 ve t0 = -2,1031 olarak hesaplanmıştır
