Gelibolu Yarımadası ve Çanakkale Boğazı'ndaki (Kuzeydoğu Akdeniz, Türkiye) Kolyoz Balığı (Scomber japonicus Houttuyn, 1782) Avcılığında Kullanılan Olta İğneleri Seçiciliklerinin Belirlenmesi

Abstract

Bu araştırmada Gelibolu Yarımadası ve Çanakkale Boğazı’nda kolyoz balığı (Scomber japonicus) avcılığında kullanılan 3, 2, 1, 1/0, 2/0, 3/0 ve 4/0 numara iğnelerin seçicilikleri SELECT metodu kullanmak suretiyle hesaplanmıştır. Bi-normal modele göre 3, 2, 1, 1/0, 2/0, 3/0 ve 4/0 numara iğnelerin optimum yakalama boyları, sırasıyla, 13, 40 cm, 14,55 cm, 15,70 cm, 16,85 cm, 19,15 cm, 20,29 cm ve 23,97 cm’dir.

Determination of Hook Selectivity Used for Catching the Chub mackerel (Scomber japonicus Houttuyn, 1782) in Dardanelles and Gallipoli Peninsula (North-eastern Mediterranean, Turkey)

Abstract

In this study, the selectivity of 3, 2, 1, 1/0, 2/0, 3/0 and 4/0 numbers hooks used for catching the Chub mackerel (Scomber japonicus) in Gallipoli Peninsula and Dardanelles was calculated by using SELECT method According to Bi-normal modal, the optimum catch lengths of 3, 2, 1, 1/0, 2/0, 3/0 and 4/0 numbers hooks were 16.85 cm, 19.15 cm, 20.29 cm and 23.97 cm, respectively,

Keywords
