Benefits of artificial reefs in Altınoluk (Northern Aegean), Turkey: Assessment of potential users' opinions via fuzzy pair wise comparison approach

Yapay resifler, kıyıya sahip birçok ülkede balıkçılık yönetimi aracı olarak kullanılmaktadır. Bu çalışmanın amacı, kullanıcı grupların yapay resiflerden faydalarını değerlendirmektir. Altınoluk’da (Edremit Körfezi, Türkiye’nin Kuzey Ege Kıyısı) kullanıcıların temel potansiyel faydalarını ortaya koymak üzere Bulanık Eşli Karşılaştırma (BEK) Yöntemi kullanıldı. Sosyal, biyolojik ve ekonomik faydaları kapsayan yapay resiflerin 3 faydası ticari balıkçılar, rekreasyonel balıkçılar ve yöre sakinlerine sunuldu. Ardından, faydaların ağırlıkları BEK Yöntemi’nde ikili kıyaslamalar ile hesaplandı. Araştırma verisi ticari ve rekreasyonel balıkçılar ile yöre sakinlerini kapsayan potansiyel kullanıcılar ile soru formu kullanarak yüz yüze görüşmeler yoluyla toplandı. BEK Yöntemi’nden elde edilen sonuçlara göre, ticari balıkçılar yapay resiflerin ekonomik faydasını en yüksek düzeyde seçerken, rekreasyonel balıkçılar ve yöre sakinleri yapay resiflerin biyolojik faydasını daha yüksek düzeyde seçmiştir. Sonuç olarak, kullanıcıların algısını ölçmeden gerçekleştirilen yapay resif uygulamaları hedefleri karşılamayabilir. Yapay resiflerin ilgili gruplarının algısını ölçmeyi amaçlayan çalışmalar planlama sürecinde karar vericilere yol gösterici olur.

Altınoluk’da (Kuzey Ege) yapay resiflerin faydaları: Bulanık eşli karşılaştırma yaklaşımı ile potansiyel kullanıcıların görüşlerinin değerlendirilmesi

Artificial Reefs (ARs) are used in many coastal countries, mainly for fisheries management purposes. The aim of this study is to assess user’s benefits from artificial reefs. Fuzzy Pair-Wise Comparison (FC) Method was used to introduce users’ opinions on main potential benefits of ARs in Altınoluk (Edremit Bay, North Aegean Coast of Turkey). Three benefits of artificial reefs including social, biological and economic were represented to commercial fishermen, recreational fishermen and local residents. Then, the weights of the benefits were calculated by pair-wise comparisons in the FC Method. Survey data was obtained by face-to-face interviews using questionnaire forms with potential users including commercial fishermen, recreational fishermen and local residents. According to the results gathered from the FC Method, commercial fishermen ranked economic benefits of artificial reefs as highest whereas recreational fishermen and local residents were agreed on biological benefits. In conclusion, ARs deployments without measuring perception of users may not meet the objectives. Studies aiming to measure the perception of AR related groups guide decision makers during the process of planning.
