Türkiye’nin Güneydoğu Akdeniz Sahillerindeki Kızıldeniz Göçmeni Sargocentron rubrum (Forsskal, 1775)’un Balık Boy ve Otolit Boyutları Arasındaki İlişkiler

Abstract

Bu çalışmada, Eylül 2017-Nisan 2018 dönemlerinde Güneydoğu Akdeniz'de (Arsuz kıyılarında) faaliyet gösteren ticari balıkçı parekete teknelerinden aylık olarak örneklenen 151 adet Kızıl akdeniz göçmeni Hindistan balığı bireylerinin balık boyu ve otolit boyutları (uzunluk, genişlik, ağırlık) arasındaki ilişkisi incelenmiştir. Sağ ve sol otolitler arasında istatistiksel fark bulunmadığından, hesaplamalarda sağ otolit çiftleri kullanıldı (P>0.05). Tüm örneklerin toplam balık uzunlukları 11.4-21.0 cm arasında değişmiştir. Tüm örnekler için otolit uzunlukları ve otolit genişlikleri 0.35-0.86 cm ile 0.26-0.56 cm arasında hesaplandı. Otolit ağırlıkları ise 0.010-0.059 g olarak belirlendi. Toplam balık boyu-otolit uzunluğu, toplam balık boyu-otolit genişliği ve toplam balık boyu-otolit ağırlık ilişkisi sırasıyla, toplam 151 örnek üzerinde; OL = 0.0512xTL + 0.186 (r² = 0.865), OWi = 0.0255xTL + 0.0021 (r² = 0.825), OW = 0.00002xTL^2.678 (r² = 0.9366) olarak belirlendi. Tüm balıklarda toplam balık boyu-otolit uzunluğu ve toplam balık boyu-otolit genişliği arasında doğrusal ilişki bulunmuştur. Çalışmanın sonuçları, alana yeni katkılar sağlayacak ve balıkçılık yönetimine faydalı olacaktır.

Relationships Between Fish Length and Otolith Dimensions of Redcoat, Sargocentron rubrum (Forsskal, 1775) in the Southeastern Mediterranean Sea, Turkey

Abstract

In the present study, sampling was monthly collected from commercial fishing longline boats operating in the southeastern Mediterranean Sea (Arsuz coast) during September 2017-April 2018 and the relationship between fish length and otolith dimensions (length, width and weight) of 151 redcoat samples were examined. Right otolith pairs were used for calculations since there were no statistical differences between left and right otoliths (P>0.05). Total fish lengths of all samples ranged from between 11.4-21.0 cm. Otolith lengths and otolith widths were calculated between 0.35-0.86 cm and 0.26-0.56 cm for all samples. Otolith weights were determined between 0.010-0.059 g. Total fish length-otolith length, total fish length-otolith width and total fish length-otolith weight relationships were determined as OL= 0.0512TL+0.186 (r²=0.865), OWi= 0.0255TL+0.0021 (r²=0.825) and OW= 0.00002TL^2.678 (r²=0.936) on the total of 151 specimens, respectively. Linear relationships between total fish length-otolith length and total fish length-otolith width were found in all fish. The results of study will have new contributions to the field and useful to fisheries management.
