Gelibolu Yarımadası’ndan (Kuzey Ege Denizi, Türkiye) Avlanan Palamut (Sarda sarda Bloch, 1793), Uskumru (Scomber scombrus Linnaeus, 1758) ve Kolyoz (Scomber colias Gmelin, 1789) Balıklarının Toplam Boy, Toplam Ağırlık, Maksimum Vücut Çevresi ve Operkulum Çevresi Arasındaki İlişkiler

Abstract

This study was carried out using dead fishes caught by commercial fishermen 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 off Gallipoli Peninsula (northern Aegean Sea, Turkey). 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
