İstanbul Boğazı’nda Setase (balinalar ve yunuslar) ordosuna ait üç türün varlığı bilinmektedir, bunlar; Phocoenidae familyasından Phocoena phocoena (Mutur) ile Delphinidae familyasından Tursiops truncatus (Afalina) ve Delphinus delphis (Tırtak)’dır. Türk Boğazlar Sistemi (TBS)’nin, Ege Denizi ve Karadeniz arasında önemli göç yolu olduğu ve setase türlerinin özellikle bahar aylarında göçebe balık türleriyle ilişkili hareketleri bilinmektedir.
Son yıllarda setase türlerinin izlenmesinde dünyada yaygın olarak kullanılan pasif akustik izleme metoduyla, Japon Ulusal Balıkçılık Araştırmaları Enstitüsü’nün desteği ile İstanbul Üniversitesi Su Bilimleri Fakültesi ile 2009 yılından beri İstanbul Boğazı’nda setase türlerinin hareketleri 24 saat kesintisiz izlenmektedir. Pasif akustik sistem olarak A-tag kullanılan çalışmada Setase sesleri klick dizileri şeklinde kaydedilerek analiz edilmektedir.
