Uzatma Ağlarının Ağ Materyali ve Yapısal Özelliklerinin Türlerin Yakalanabilirliği ve Tür Seçiciliği Üzerindeki Etkisi.

Bu araştırmada, monofilament ve multifilament materyale sahip fanyalı ve sade uzatma ağlarının av kompozisyonu, türlerin yakalanabilirliği ve tür seçiciliği karşılaştırılmıştır. Denemelerde kullanılan ağların göz açıklığı 36 mm dir. Türlerin % 58,81’i monofilament, % 41,19’u multifilament ağlarla yakalanmıştır. Monofilament ağlarla yakalananların % 95,84’ü, multifilamentlerin ise % 92,67’sinin ekonomik olduğu bulunmuştur. Tüm ekonomik türler içerisinde multifilament ağların payı % 40,38, monofilament ağların payı ise % 59.62 olarak tespit edilmiştir. Hem avlanan balık miktarı hem de hedef tür yakalama oranı yönünden sade ağların fanyalı ağlara oranla daha verimli olduğu belirlenmiştir. Hedef türleri oluşturan istavrit (Trachurus trachurus, L. 1758), barbunya (Mullus barbatus ponticus, E., 1927) ve mezgit (Merlangius merlangus euxinus, N. 1840) balıkların boy kompozisyonları incelendiğinde; sade ağların fanyalı ağlara, multifilament ağların monofilament ağlara göre daha (p
