Abstract

---

In August 2020, a total area of 38000 m2 around Gökçeada has been scanned to determine the current population status of Pinna nobilis. 9 stations (Yıldızkoy, Manastır, Marmaros, Gizli Liman, Laz Koyu, Kapıkaya, Karaçavuş, Karaçavuş shore and Kefalos) have been detected by means of SCUBA and ABC diving techniques. All specimens were found dead (total mass mortality of 100%). The total length range of P. nobilis was between 30.8 – 38.3 cm.

Pinna nobilis’in mevcut populasyon durumunu ortaya koymak için, 2020 Ağustos ayında Gökçeada kıyılarında, 38000 m2’lik bir alan incelenmiştir. 9 istasyon (Yıldızkoy, Manastır, Marmaros, Gizli Liman, Laz Koyu, Kapıkaya, Karaçavuş, Karaçavuş altı ve Kefalos), SCUBA ve ABC dalış teknikleri kullanılarak taranmıştır. Çalışma süresince bulunan bütün bireyler ölüdür (%100 kütlesel ölüm görülmüştür). P. nobilis ‘in toplam boy aralığı 30,8 – 38,3 cm arasında ölçülmüştür.
