Abstract

This study reports the first-recorded presence of the Korean rockfish (Sebastes schlegelii) in the Sea of Marmara, signifying a notable geographical expansion beyond its natural range. The sampled male specimen, with a total length of 27.5 cm and a weight of 459.20 g, aligns with known size patterns observed in the Black Sea, suggesting a consistent trend. The unexpected presence of the species in the Sea of Marmara raises intriguing questions about its potential spread in the broader Mediterranean Sea basin. The adaptability of the Sebastes schlegelii to diverse environmental conditions underscores its ecological resilience. The study emphasizes the need for careful monitoring and management due to potential threats posed by invasive species, especially considering the vulnerabilities of the Sea of Marmara to climate change

Sebastes schlegelii'nin Marmara Denizi'ndeki İlk Kaydı ve Coğrafi Yayılım Genişlemesi

Abstract

Bu çalışma, Kore kaya balığı Sebastes schlegelii‘nin doğal yayılışının ötesinde dikkate değer bir coğrafi yayılımı işaret ederek Marmara Denizi'nde ilk kaydını bildirmektedir. Toplam uzunluğu 27,5 cm ve ağırlığı 459,20 g olan erkek birey, Karadeniz'de gözlemlenen bilinen boyut modelleriyle aynı hizada olup tutarlı bir eğilime işaret etmektedir. Türün Marmara Denizi'ndeki beklenmedik varlığı, daha geniş Akdeniz havzasındaki yayılma potansiyeli hakkında ilgi çekici soruları gündeme getirmektedir. Sebastes schlegelii‘nin çeşitli çevresel koşullara uyum sağlama yeteneği, türün ekolojik dayanıklılığını göstermektedir. Çalışma, özellikle Marmara Denizi'nin iklim değişikliğine karşı hassasiyeti göz önüne alındığında, istilacı türlerin oluşturduğu potansiyel tehditler nedeniyle dikkatli izleme ve yönetim ihtiyacını vurgulamaktadır
