Gelibolu Yarımadası ve Çanakkale Boğazı’nda (Kuzey Ege Denizi, Türkiye) Lüfer Balığı için (Pomatomus saltatrix Linneaus, 1766) İğne Seçiciliği

Abstract

Bu çalışma, Gelibolu Yarımadası ve Çanakkale Boğazı’ndaki lüfer balığı (Pomatomus saltatrix Linnaeus, 1766) avcılığında kullanılan olta iğneleri seçiciliklerini belirlemek için, 2006-2009 balıkçılık sezonunda, lüfer göç zamanı olan Eylül, Ekim ve Kasım ayları arasında gerçekleştirilmiştir. Lüfer balıklarının avcılığı 1, 1/0, 2/0, 3/0, 4/0 numara iğneler ile gerçekleştirilmiş ve 1210 adet lüfer balığı yakalanmıştır. En fazla birey 2/0 numara iğne ile (344 birey, % 20,43) en az birey ise 1 numaralı iğne ile (35 birey, % 2,89) elde edilmiştir. Farklı iğne numaraları ile avlanan lüfer balığının boy frekans dağılımları kullanılarak uygulanan SELECT metoduna göre en uygun model, normal scale model olarak saptanmıştır. Normal scale modele göre kullanılan iğne büyüklükleri için hesaplanan optimum yakalama boyları (OYB) ve eğrinin genişlikleri (EG), sırasıyla, 1 no’lu iğne için 19,18 cm OYB ve 4,44 EG; 1/0 no’lu iğne için 21,88 cm OYB ve 5,07 EG; 2/0 no’lu iğne için 24,14 cm OYB ve 5,59 EG; 3/0 no’lu iğne için 27,02 cm OYB ve 6,26 EG ve 4/0 no’lu iğne için 28,19 cm OYB ve 6,53 EG’dir. Lüfer balıklarının Türkiye’deki minimum avlanma boyu 20 cm olduğu için lüfer avcılığında 2/0 numara ve daha büyük iğnelerin kullanımı önerilebilir

Hook Selectivity for Bluefish (Pomatomus saltatrix Linneaus, 1766) in Gallipoli Peninsula and Çanakkale Strait (Northern Aegean Sea, Turkey)

Abstract

This study was conducted to determine the selectivity of the hooks used for bluefish (Pomatomus saltatrix Linneaus, 1766) in the Gallipoli Peninsula and the Dardanelles between 2006 and 2009 fishing seasons (November to September). Bluefish were fished with hooks sized 1, 1/0, 2/0, 3/0, 4/0 and in sum; 1210 bluefish were caught. The hook no 2/0 caught the highest number of fish (344 fish, 20.43%) and the hook no 1 caught the least (35 fish, 2.89%). Length frequency distribution of bluefish, which were caught with different hook sizes, was used in SELECT method and according to the results; the normal scale model gave the best fit for selectivity. The normal scale model was used to calculate model length (ML) and spread value (SV) of each hook size. Model length and spread value were found as follows; 19.18 cm ML and 4.44 SV for hook no. 1; 21.88 cm ML, 5.07 SV for hook no 1/0; 24.14 cm ML, 5.59 SV for hook no. 2/0; 27.02 cm ML, 6.26 SV for hook no. 3/0; 28.19 cm ML, 6.53 SV for hook no. 4/0, respectively. Because the minimum landing size (MLS) for bluefish has been stipulated as 20.0 cm (TL) in the Turkish Fishery Regulations, the use of hook no. 2/0 or bigger hook sizes can be recommended for fishing of bluefish.
