Abstract

To determine the selectivity of gill nets with 22, 23, 25 and 28 mm nominal mesh size (bar length) for bluefish (Pomatamus saltatrix, L. 1766), the study was conducted at three different stations between 20 and 30 m water depths at Çanakkale Strait, Turkey, between February 2007 and April 2012. Gill net with 22, 23, 25 and 28 mm mesh size (bar length) each having same twine thickness (210 denier / 3) and 100 mesh depth vertically were rigged for this purpose. The fish samples were obtained by drive-in fishery method during winter season. The SELECT method was used in determining selectivity parameters. By comparing the deviances of five different models of SELECT method, lognormal model gave the best fit. The modal lengths of the gill nets with 22, 23, 25, and 28 mm mesh size were estimated 22.24, 23.25, 25.27 and 28.30 cm, respectively. The results of the trials indicated that minimum gill net mesh size for this fish should use larger than 25 mm

Abstract

Çalışma 22, 23, 25, ve 28 mm göz genişliğindeki uzatma ağlarının lüfer balığındaki (Pomatamus saltatrix, L. 1766) seçiciliğini belirlemek için, Şubat 2007 – Nisan 2012 tarihleri arasında, Çanakkale Boğazı’nda 20 – 30 m derinlikler arasında, üç farklı istasyonda gerçekleştirilmiştir. Bu amaçla, aynı ip kalınlığına ve vertikal olarak 100 göz derinliğe sahip 22, 23, 25 ve 28 mm göz genişliğinde (Fabrika tarafından verilen ağ gözünün bir kenarının uzunluğu) uzatma ağları donatıldı. Balık örnekleri kış mevsiminde Çanakkale Boğazı’nda gerçekleştirilen voli yöntemi ile yapılan avcılıktan elde edilmiştir. Seçicilik parametrelerinin tespitinde SELECT metot kullanılmıştır. Bu metotta beş farklı modelde yapılan analizler sonucunda, iyi sonucu lognormal model vermiştir. Analiz sonucunda 22, 23, 25 ve 28 mm göz genişliğindeki ağlara göre optimum yakalama boyları sırası ile 22.24, 23.25, 25.27 ve 28.30 cm bulunmuştur. Yapılan denemelerin sonuçları bu balığın avcılığının 25 mm’den daha büyük göz genişliğine sahip ağlarla yapılması gerektiğini göstermiştir.
