Özet:

 This study analyses a highly damaging and prevalent fishing practice of trawl infringements, which is one of the crucial components of IUU fishing in Turkish waters. The raw data gathered from the Turkish Coast Guard Command TURCG, covered 2012  2014 period. Data covered a total of 1040 trawl infringements, with considerable differences in trawling violations among the seas surrounding Türkiye; the Black Sea, the Sea of Marmara, the Aegean Sea, and the Mediterranean Sea. With respect to trawling infringements, the Sea of Marmara 37 and Istanbul Strait 15 were the hot points. The most common infringement type was trawling in a closed area 43 and when combined with the rate of infringements on trawling during the closed season 10, these violations accounted for 53 of spatio-temporal infringements. Regarding illegal trawling by vessel type, trawl vessels had a 44 share and non-trawlers had a share of 56, of which included infringements by other type of fishing vessels 46 and non-fishing vessels 10. It was also found that infringement by vessels smaller than 12 meters in length had a share of 46. These vessels known as şebeke in Turkish, trawl illegally using small types of nets and gears in coastal waters without giving any obvious indication of fishing activity. The results of this study will be useful to policy-makers, practitioners and scientists to successfully combat trawling infringements by providing information on distribution, intensity and methods of trawl violations.

 Bu çalışma, Türkiye Denizlerinde YKK Yasa Dışı, Kayıt Dışı, Kural Dışı balıkçılığın en zararlı ve yaygın bileşenlerinden biri olan trol ihlallerini analiz etmektedir. Çalışmaya ait ham veriler, Sahil Güvenlik Komutanlığından 2012-2014 döneminde temin edilmiştir. Toplam 1040 trol ihlaline ait veriler incelendiğinde, Türkiyeyi çevreleyen Karadeniz, Marmara Denizi, Ege Denizi ve Akdeniz arasında trol ihlalleri bakımından dikkate değer farklılıklar olduğu tespit edilmiştir. Trol ihlalleri bakımından Marmara Denizi 37 ve İstanbul Boğazı 15 kendi ölçeklerinde en sıcak noktalar olarak bulunmuştur. En yaygın ihlal türü 43 ile yasak sahada trol çekmek olup, yasak zamanda trol çekme ihlalleri ilave edildiğinde zamansal-mekansal ihlallerin 53e ulaştığı gözlemlenmiştir. Yasadışı trol avcılığı gemi türü bakımından incelendiğinde ise trol gemileri 44lük bir paya sahipken, diğer balıkçı gemileri 46 ve balıkçılık ruhsatına sahip olmayan gemilerin  10 oluşturduğu trol ruhsatına sahip olmayan gemiler 56 paya sahip olmuştur. Ayrıca boyu 12 metreden küçük olan gemilerin ihlaller içinde  46 gibi önemli bir paya sahip olduğu tespit edilmiştir. Bu gemiler Türkçede şebeke olarak adlandırılmaktadır, dışarıya hiçbir emare vermeden küçük boyuttaki ağlar ve takımlarla kıyı sularında gizlice trol çekebilmektedir. Bu çalışmanın sonuçları, trol ihlallerinin dağılımı, yoğunluğu ve metotları hakkında bilgi vererek, trol ihlalleriyle etkin mücadele kapsamında uygulayıcılara, politika yapıcılara ve bilim insanlarına faydalı olacaktır.
