Özet:

 Sebastes schlegelii is a typical bottom dwelling boreal species, whose native distribution range includes Japan, Korean peninsula and China. This northwest Pacific originated species has recently been recorded from the Crimean and Caucasian coast northern Black Sea, whose introduction was assumed to be either by balast waters or the acclimatization of Crassostrea gigas Pacific oyster. On 16 August 2023, a single S. schlegelii specimen with 20.6 cm standard length and 282.1 g in weight was captured off Ünye, Ordu coast southeastern Black Sea, which was previously an unreported fish from the Turkish marine waters. Detailed morphometric and meristic characteristics are presented in the paper, and species identification was further confirmed by genetic analysis. Available information reveals this alien species to be fished regularly, although in small quantities, indicating a presumably established population in the region. The species should be treated as a potentially invasive fish, since it may negatively influence to the local biodiversity through interspecific competition. Close monitoring of its existing population is strongly suggested.

 Sebastes schlegelii, doğal dağılım alanı Japonya, Kore yarımadası ve Çini kapsayan tipik bir demersal boreal türdür. Kuzeybatı Pasifik kökenli bu tür, yakın zamanda Kırım ve Kafkasya kıyılarında Kuzey Karadeniz kaydedilmiş olup, ekosisteme girişinin ya gemilerin balast suları ya da Crassostrea gigasın Pasifik istiridyesi yetiştiriciliği ile alakalı olduğu varsayılmaktadır. 16 Ağustos 2023 tarihinde Ordu Ünye açıklarında Güneydoğu Karadeniz 20,6 cm standart boyda ve 282,1 g ağırlığında bir S. schlegelii örneği elde edilmiş olup, türün daha önce Türkiye denizlerinde var olduğuna dair bir kayıt bulunmamaktadır. Bu makalede detaylı morfometrik ve meristik karakterler sunulmuş olup, tür tayini genetik analiz ile de doğrulanmıştır. Mevcut bilgiler, söz konusu yabancı türün küçük miktarlarda da olsa düzenli olarak avlandığını ortaya koymakta ve bölgede muhtemelen başarılı bir popülasyonun oluştuğunu göstermektedir. Bu tür potansiyel olarak istilacı bir balık olarak kabul edilmelidir, zira interspesifik rekabet yoluyla yerel biyolojik çeşitliliği olumsuz yönde etkileme ihtimali bulunmaktadır. Mevcut popülasyonun yakından takip edilmesi büyük önem taşımaktadır.
