Abstract

Demersal trawling is among the most energy-intensive fishing practices worldwide, primarily due to the drag and frictional force caused by their heavy components. This study aimed to estimate fuel use intensity (litres of fuel per kilogram of landed catch) and associated carbon dioxide emissions of Turkish trawl vessels, most of which still operate using traditional trawl nets equipped with heavy otter boards and lead ground gear, increasing towing resistance and consequently fuel consumption. Data from 129 commercial fishing trips conducted by 13 trawl vessels between 2021 and 2022 were analysed using Generalized Linear Models (GLMs). Overall, to catch one kg of landed marine product, the trawl vessels consumed approximately a median value of 1.22 litres of fuel and emitted 3.21 kg of CO2 for the given period. Vessel length, engine power and the target species group were the main factors affecting the fuel use intensity. The results obtained from the study provide critical insights for implementing effective management measures to decarbonize fisheries, offering practical recommendations for decision makers. Expanding the dataset to encompass a broad range of vessels, regions, and fishing seasons would further enhance the generalizability and applicability across different fisheries.

Thanks

I extend my gratitude to the captains and crew of the 13 trawl vessels for their dedication to this study in terms of data collection. Without their hospitality and patience, this work would not have been accomplished. I would like to acknowledge two fisheries observers on board, Yaşar İşitmez and Murat Uzun for their support and effort in collecting the data essential for this research. I would like to express my sincere gratitude to Gökhan Gökçe and Hüseyin Özbilgin for their invaluable guidance, insightful feedback, and unwavering support throughout the course of this research. Their expertise and encouragement have been instrumental in shaping this work.

Abstract

Dip trolleri, ağır bileşenlerinden kaynaklanan sürükleme direnci ve sürtünme kuvveti nedeniyle dünyanın en yoğun enerji tüketen balıkçılık yöntemlerinden biridir. Bu çalışma, çoğu hala çekme direncini ve yakıt tüketimini artıran ağır kapılar ve kurşun yakalarla donatılmış geleneksel trol ağlarıyla çalışan Türk trol teknelerinin yakıt kullanım yoğunluğunu (karaya çıkarılan bir kilogram av başına kullanılan yakıt) ve ilgili karbondioksit emisyonlarını tahmin etmeyi amaçlamıştır. 2021-2022 yıllarında 13 trol teknesiyle gerçekleştirilen 129 ticari balıkçılık seferinden elde edilen veriler Genelleştirilmiş Doğrusal Modeller kullanılarak analiz edilmiştir. Genel olarak, bir kilogram deniz ürünü avlamak için medyan değeri yaklaşık 1,22 litre yakıt tüketilmiş ve söz konusu dönemde 3,21 kg CO2 salınmıştır. Tekne boyu, motor gücü ve hedeflenen tür grubu, yakıt kullanım yoğunluğunu etkileyen başlıca faktörler olarak belirlenmiştir. Mevcut çalışma, balıkçılık sektörünün karbonsuzlaştırılması için etkili yönetim önlemlerinin uygulanmasına yönelik kritik bilgiler sağlayarak karar alıcılar için pratik öneriler sunmaktadır. Daha geniş filo, farklı bölgeler ve balıkçılık sezonlarını kapsayacak şekilde veri setinin genişletilmesi, elde edilen sonuçların genellenebilirliğini ve farklı balıkçılıklarda uygulanabilirliğini daha da geliştirecektir.
