Bu çalışmada, 35 mm yatay çubuk aralığına sahip seçicilik ızgarası ile bakalyaro (M. merluccius L., 1758), barbunya (M. barbatus L., 1758) ve ısparoz (D. annularis L.,1758) seçiciliği araştırılmıştır. Denemeler geleneksel trol ağı (600 göz) ile Ege Denizi’nde Nisan 2003’de gerçekleştirilmiştir. Seçicilik ızgarası tünelin arka kısmına monte edilmiştir. Seçicilik ızgarasının önünde ve üst torbada kalan bireylerin toplamı ile ızgaradan kaçan bireyler, seçiciğinin tahmininde kullanılmıştır. Seçicilik verileri örtü torba yöntemi gibi logit fonksiyonun maksimum olabilirlik yöntemi ile analiz edilmiştir. Ortalama seçicilik eğrisi, bireysel çekimler arası varyasyon göz önüne bulundurularak tahmin edilmiştir. Ağırlık olarak toplam avın %56’sı yakalanmış, %44’ü kaçmıştır. Ortalama L50 değeri bakalyaro, barbunya ve ısparoz için sırasıyla 24,7cm ±1,1, 11,7 cm ±0,1 ve 15,4 cm ± 0,1 olarak bulunmuştur. 35 mm yatay bar aralığına sahip seçicilik ızgarası bakalyaro için ağ gözü büyüklüğü ve şekli ile diğer dikey ızgara tasarımıyla karşılaştırıldığında oldukça iyi seçicilik yüksek L50 değeri vermiştir. Bununla birlikte bu tasarım ısparoz için aşırı, barbunya içinse düşük seçicilik göstermiştir
