Abstract

This study aimed to determine the relationships between length-weight and length-length relationships in 221 Garfish Belone belone individual caught between October and November 2018 in the Sea of Marmara and Black Sea coasts of Kocaeli. Black Sea samples were caught from Kocaeli Kandıra (79 ♀, 29 ♂), Sea of Marmara samples from Kocaeli Darıca (87 ♀, 26 ♂). The total length of the samples obtained in the study is between 30.4-44.5 cm in the Black Sea and 27.9-51.6 cm in the Sea of Marmara. Their weights range between 32.6-92.0 g in the Black Sea and between 15.4-91.6 g in the Sea of Marmara. Since the differences between all values of male and female individuals in both populations were not statistically different (P>0.05), calculations were made from all individuals. The length-weight relationship equations were calculated as W= 0,0006L3,171 (R2=0.91) in Blacksea samples, as W= 0,0007L3,115 (R2=0.96) Sea of Marmara samples for all specimens. The “b” value of LWR was significantly different from 3.0 (P<0.05) and their growth type was positive allometric. The relation equations of total length-fork length, total length-standard length ve fork length-standard length in the populations of Sea of Marmara and Black Sea were also determined.

Kocaeli (Türkiye)’nin Farklı Sahillerinde Yaşayan Zargana Belone belone için Boy-Ağırlık ve Boy-Boy İlişkilerinin Tespiti

Abstract

Bu araştırmada, Kocaeli’nin Karadeniz ve Marmara Denizi kıyılarından Ekim-Kasım 2018 tarihleri arasında yakalanan 221 adet Zargana Belone belone bireyinin boy-ağırlık ve boy-boy ilişkilerinin belirlenmesi amaçlanmıştır. Karadeniz örnekleri Kocaeli Kandıra’dan (79 ♀, 29 ♂), Marmara Denizi örnekleri Kocaeli Darıca’dan (87 ♀, 26 ♂) yakalanmıştır. Çalışmada elde edilen örneklerin total boyları Karadeniz’de 30,4-44,5 cm iken, Marmara Denizi’nde 27,9-51,6 cm aralığındadır. Ağırlıkları ise Karadeniz’de 32,6-92,0 g ve Marmara Denizi’nde 15,4-91,6 g arasında dağılım göstermektedir. Her iki popülasyon için, dişi ve erkek bireylerde tüm değerler arasındaki fark istatistiksel olarak önemsiz bulunduğundan (P>0,05) hesaplamalar tüm bireyler üzerinden yapılmıştır. Tüm bireyler için boy-ağırlık ilişki denklemi Karadeniz’de W= 0,0006L3,171 (R2=0,91); Marmara Denizi’nde W= 0,0007L3,115 (R2=0,96) olarak hesaplanmıştır. Her iki popülasyonda da boy-ağırlık ilişkisinin “b” değeri, 3’den önemli derecede farklıdır (P<0,05) ve türün büyümesinin pozitif allometrik olduğu belirlenmiştir. B. belone türünün Karadeniz ve Marmara Denizi popülasyonlarında total boy-çatal boy, total boy-standart boy ve çatal boy-standart boy ilişki denklemleri de belirlenmiştir.
