This study was carried out using dead fishes caught by commercial fishermen of Gallipoli Peninsula (northern Aegean Sea, Turkey)to find out length-girth and length-weight relationships of atlantic bonito (Sarda sarda Bloch, 1793), atlantic mackerel (Scomber scombrus Linnaeus, 1758) and atlantic chub mackerel (Scomber colias Gmelin, 1789) between January 2017 and December 2017. The length-weight relationships were estimated as W=0.0143TL2.84 (R2=0.89), W=0.0059TL3.11 (R2=0.92) and W=0.0059TL3.11 (R2=0.92) for Sarda sarda, Scomber scombrus and Scomber colias, respectively. The length-opercular girth relationships were calculated as Gope=0.3988TL+0.2512 (R2=0.78), Gope=0.3528TL+0.8122 (R2=0.84) and Gope=0.4295TL-0.5991 (R2=0.94), whereas the length-maximum girth relationships were determined to be Gmax=0.5993TL-4.1237 (R2=0.79), Gmax=0.4206TL+0.2732 (R2=0.83) and Gmax=0.4676TL-0.168 for Sarda sarda, Scomber scombrus and Scomber colias, respectively. The present study includes preliminary information on length-opercular girth and length-maximum girth relationships of these fish species for the Mediterranean Basin including Black Sea.
Bu çalışma Gelibolu Yarımadası açıklarında (Kuzey Ege Denizi, Türkiye) Ocak 2017-Aralık 2017 tarihleri arasında palamut (Sarda sarda Bloch, 1793), uskumru (Scomber scombrus Linnaeus, 1758) ve kolyoz (Scomber colias Gmelin, 1789) türlerinin boy-ağırlık ve boy-çevre ilişkilerini ortaya çıkarmak için ticari balıkçılar tarafından avlanan öü balıkları kullanmak suretiyle gerçekleştirilmiştir. Boy-ağırlık ilişkisi palamut, uskumru ve kolyoz balıkları için, sırasıyla, W=0.0143TL2.84 (R2=0.89), W=0.0059TL3.11 (R2=0.92) ve W=0.0059TL3.11 (R2=0.92) olarak tahmin edildi. Yine sırasıyla bu türlerin boy-operkulum çevre ilişkileri Gope=0.3988TL+0.2512 (R2=0.78), Gope=0.3528TL+0.8122 (R2=0.84) ve Gope=0.4295TL-0.5991 (R2=0.94) olarak hesaplanırken boy-maksimum vücut çevre ilişkileri ise Gmak=0.5993TL-4.1237 (R2=0.79), Gmak=0.4206TL+0.2732 (R2=0.83) ve Gmak=0.4676TL-0.168 olarak saptanmıştır. Bu çalışma Karadeniz’i de kapsayacak şekilde tüm Akdeniz Havzası için bu türlerin boy-operkulum ve boy-maksimum vücut çevresi ile ilgili ilk bilgileri içermektedir.
