Abstract

This study, conducted from October 2019 to September 2021 in the regions of the Çanakkale Strait and the Northern Aegean incleuding, Kepez, Kumkale, Yeniköy, Dardanos, Güzelyalı, Morto Bay, and Saros Bay. 162 individuals of the species Scorpaena scrofa examined. The total weights and lengths of the individuals were recorded. The average otolith weights of female and male individuals were found to be 0.023 g and 0.023 g, respectively (P<0.05); otolith lengths were 5.13 mm and 4.67 mm (P<0.05); and otolith widths were 2.01 mm and 1.87 mm (P<0.05), respectively. It was determined that males had smaller values than females across all three otolith biometric measurements, and these differences were statiscially significant. Additionally, there were no differences in size between the left and right otoliths (P>0.05). The lenght-weight relationship analysis indicated that the species exhibited isometric growth, with b values approaching 3.

Çanakkale Bölgesinde Bulunan Scorpaena scrofa (Linnaeus, 1758)'nın Boy-Ağırlık İlişkisi ve Otolit Biyometri Özelliklerinin Belirlenmesi

Abstract

Bu çalışma Ekim 2019 – Eylül 2021 tarihleri arasında Çanakkale Boğazı ve Kuzey Ege Denizi olmak üzere; (Kepez, Kumkale, Yeniköy, Dardanos, Güzelyalı, Morto Koyu ve Saroz Körfezi) mevkilerinde gerçekleştirilmiştir. Scorpaena scrofa türünden toplam 162 birey temin edilmiştir. Bireylerin toplam ve standart ağırlıkları ile boyları belirlenmiştir. Dişi ve erkek bireylerin ortalama otolit ağırlıkları sırasıyla 0,023 g- 0,023 g (P<0,05); otolit boyları 5,13 mm- 4,67 mm (P<0,05); otolit genişlikleri ise 2,01 mm- 1,87 mm (P<0,05) olarak belirlenmiştir. Tüm üç otolit biyometrisinde, erkek bireylerin dişi bireylere karşılık olarak daha küçük değerlere sahip olduğu ve aralarındaki farkın istatistiksel olarak anlamlı olduğu bulunmuştur. Ayrıca otolit çiftleri sol ve sağ oluşuna göre de karşılaştırılmış, ancak aralarındaki büyüklük farkının önemsiz olduğu (P>0,05) saptanmıştır. Boy – ağırlık ilişkisi hesaplamalarında ise türün genel olarak b değerleri 3’e yakın olduğu için izometrik büyüme gösterdiği tespit edilmiştir.
