Abstract

One specimen of Korean rockfish Sebastes schlegelii Hilgendorf, 1880 was caught by using fish net at a depth of 7 m on 14 May 2022 from Akçakoca, Düzce in Black Sea. In this study, the Korean rockfish Sebastes schlegelii from the Black Sea coast of Türkiye is reported for the first time with both morphologic and genetic evidence. S. schlegelii is characterised by 5 spines on the preoperculum and 2 spines on operculum. Genetic analyses using mtDNA COI gene region also confirmed the species as Sebastes schlegelii. This species is thought to have been transported to the Black Sea from other seas of the world, probably via ballast waters or aquarium escape. The most important reason for this is that the species has not been detected in the Mediterranean.

Thanks

Thanks to fisherman Hüseyin Demircioğlu (Taşçı Hüseyin) and Hasan Tiryaki who contributed to the delivery of the grouper to us and its preservation under suitable conditions until it can be examined. We would like to express our gratitude to Ege Veterinary Clinic (Aykut Ekinci) for their X-ray services. We extend our gratitude to Volkan Demircioğlu and Cem Yavuzyiğit for their assistance in providing us with photographs of the individuals caught in other provinces along the Black Sea coast of Türkiye.
