Abstract

The present study reports the age, growth, and reproduction parameters of 52 brown rays (Raja miraletus) captured from the Saros Bay (Northern Aegean Sea) between September 2006 -2008. The males and females accounted for 44.2% and 55.8% of the sample, respectively. The males measured 10.5-53.5 cm (disc width, 6.5-32 cm) and the females ranged 25.5-47.7 cm (disc width, 18-30.5 cm) in total length (TL). The equations TW=0.0017*TL3.27 and TW=0.0017*DW3.38 were used to describe the total length-weight and disc width-weight relationships, respectively. The length-at-age data on vertebrae were used to estimate the von Bertalanffy growth equation: L∞ = 62.43 cm, K = 0.28 year−1, t0 = −0.54 year. The maximum age was found to be 4 years for both the males and females.

Saros Körfezi’nde (Kuzey Ege Denizi) Kahverengi Vatozun (Raja miraletus Linnaeus, 1758) Biyolojik Yönleri

Abstract

Bu çalışmada, Kuzey Ege Denizi, Saros Körfezi’nde, Eylül 2006 ve 2008 tarihleri arasında, 52 adet kahverengi vatozun (Raja miraletus) yaş, büyüme ve üremesi çalışılmıştır. Cinsiyet kompozisyonu %44,2 erkeklerden ve %55,8 dişilerden oluşmuştur. Erkeklerin toplam boy aralıkları 10,5’den 53,5 cm’e (disk genişliği, 6,5-32 cm), ve dişilerin 25,5’den 47,7 cm’e (disk genişliği, 18-30,5 cm) olarak değişmiştir. Boy-ağırlık ve disk genişliği-ağırlık ilişkileri sırasıyla, TA=0,0017*TB3,27 and TA=0,0055*DG3,38 olarak tanımlanmıştır. Omur okumalarından boy-yaş verilerine dayanılarak hesaplanan von Bertalanffy denklemindeki büyüme parametreleri: L∞ = 62,43 cm, K = 0,28 yıl−1, t0 = −0,54 yıl olarak hesaplanmıştır. Maksimum yaşının 4 yıl olduğu tespit edilmiştir.
