Abstract

In this study, 10 trawl operations were made between November 2013 and April 2014 in the Iskenderun Bay. In these opeartions, video and imaging records were carried out with systems modified in the trawl hauling in the Iskenderun Bay. As a result of these studies, images were obtained in support of the selectivity studies in the region trawl fish. Modification underwater trawl cam used in these studies are more effective and less costly than commercial trawl cameras.

Trol Torbasinda Farklı Görüntüleme Sistemleri İle Görsel Seçicilik Değerlendirmeleri

Abstract

Bu çalışmada Kasım 2013 ile Nisan 2014 arasında İskenderun Körfezi’nde 10 trol operasyonu gerçekleştirilmiştir. Bu operasyonlarda İskenderun Körfezi trol balıkçılığında trol ağ torbasında modifiye edilen görüntüleme sistemleri ile video ve resimleme çalışmaları yapılmıştır. Bu çalışmalar sonucunda bölge trol balıkçılığındaki seçicilik çalışmalarını destekler nitelikte görüntüler alınmıştır. Bu çalışmalarda kullanılan modifiye sitemeler hazır bulunan sualtı kameralarına nazaran daha efektif ve maliyeti düşük olmaktadır.
