N2  - Bu çalışmada, Marmara Gölü’ndeki sazan balığı (Cyprinus carpio L., 1758) için multifilament fanyalı ve galsama uzatma ağlarının seçicilik özelliklerinin tahmin edilmesi amaçlanmıştır. 210d/2 ip kalınlığına ve 4, 6, 8, 10 cm ağ gözü açıklığına sahip fanyalı ve galsama ağlar Marmara Gölü’nde test edilmiştir. Ayrıca elde edilen verilerle 11, 12, 13 ve 14 cm göz açıklığındaki fanyalı ve galsama uzatma ağlarının optimum yakalama boyları için modelleme yapılmıştır. Seçicilik parametrelerinin tahmininde SELECT metot kullanılmıştır. Avcılık denemeleri gölü yatay olarak temsil edecek şekilde; batı, orta ve doğu kısmından belirlenen üç farklı istasyonda aylık olarak yürütülmüştür. Hem fanyalı hem de galsama ağları ile 36 adet avcılık denemesi yapılmıştır. 11,3 - 49,0 cm boy aralığında toplam 119 adet sazan yakalanmıştır. Hem fanyalı hem de galsama ağları için en düşük sapmayı veren Bi-normal modele göre; 4, 6, 8, 10, 11, 12, 13 ve 14 cm göz açıklığındaki fanyalı ağların model boyları; 12,98, 19,47, 25,96, 32,45, 35,70, 38,94 ve 42,19 cm, aynı göz açıklığındaki galsama ağları için model boyları 12,40, 18,60, 24,80, 31,00, 34,10, 37,20, 40,30 ve 43,40 cm, olarak tahmin edilmiştir. Sazan balığının 40 cm minimum avlama boyu göz önüne alındığında, 13 cm göz açıklığının altındaki hem galsama hem de fanyalı uzatma ağlarının yasaklanması tavsiye edilmektedir
