Uzatma ağlarında ip kalınlığının Marmara Gölü’ndeki sazan (Cyprinus carpio Linnaeus, 1758) avcılığında av verimi ve seçicilik üzerine etkisi

Öz

Bu çalışma ile sazan avcılığında kullanılan multifilament sade uzatma ağlarının ip kalınlığının, seçicilik ve av verimliliği üzerine etkileri araştırılmıştır. Denemeler, Türkiye’nin batısındaki Marmara Gölü’nde, 140, 150, 160, 180, 200 mm tam göz boyundaki multifilament sade uzatma ağları ile iki farklı ip kalınlığında (210d/2 ve 210d/3), Haziran 2015 ve Aralık 2016 tarihleri arasında gerçekleştirilmiştir. Kalın ipte (210d/3), aynı göz genişliğindeki ince ipe göre (210d/2) daha yüksek model boyları, daha düşük birim çabaya düşen av miktarı (CPUE) değerleri ve daha düşük oranda yasal yakalama boyu (YYB) altında balık (180 ve 200 mm tam göz boyları hariç) elde edilmiştir. Her iki ip kalınlığında tüm ağ göz genişliklerinde YYB üzerinde model boyları sağlanmıştır. Ancak, tüm ağ boyları birlikte değerlendirildiğinde ince ipte YYB altı balık oranı (%8), toplam av için kabul edilen yasal sınırın (%5) üzerinde çıkmıştır. Sonuç olarak, kalın iple model boyları ve yayılım değerleri artmış, seçicilik ve av verimi azalmıştır.

The effect of gillnet twine thickness on catching efficiency and selectivity for common carp (Cyprinus carpio Linnaeus, 1758) fishery in Marmara Lake

Abstract

The effects of multifilament gillnet twine thickness on selectivity and catching efficiency for the common carp fishery were investigated in this study. Sampling was carried out with multifilament gillnets of two different twine thicknesses (with 210d/2 and 210d/3) on 140, 150, 160, 180, 200 mm mesh sizes between June 2015 and December 2016 in Marmara Lake, located in Western Turkey. Higher modal lengths and lower catch per unit effort (CPUE) values and lower sub-minimum landing size (MLS) individuals rate (excluding 180 and 200 mm mesh sizes) were obtained in the thick multifilament material (210d/3) with the same mesh size compared to thin material (210d/2). All mesh sizes in both twine thickness provided modal lengths above the MLS. However, the thin twine material had a higher nominal percentage of undersized fish (8%), greater than the 5% accepted limit for total catches when all mesh sizes are considered together. As a result, the modal lengths and spread values increased and the selectivity and catching efficiency decreased with the thicker twine material.
