Abstract

This study examined the growth and morphometric development of Ostrea edulis cultured in suspended net bags within an active mussel farm on the Erdek coast of the Sea of Marmara, Türkiye, from March 2018 to March 2019. Monthly measurements of shell length, shell width, shell thickness and wet weight were recorded together with seawater temperature, salinity, dissolved oxygen and chlorophyll-a concentration. During the study period, seawater temperature ranged from 9.0 to 25.9 °C, while salinity varied between 23.8 and 26.2 PSU. Mean shell length increased from 22.97 ± 6.48 mm to 84.03 ± 11.16 mm, and mean wet weight increased from 2.06 ± 1.82 g to 72.85 ± 18.97 g. Survival was 95%. The highest length- and weight-based specific growth rates were observed during the May–June interval, followed by a gradual decline toward winter. Growth showed a possible seasonal association with seawater temperature, whereas the relationship with chlorophyll-a was less direct. These results provide preliminary, site-specific information on the suspended culture performance of O. edulis within an active mussel-farm environment in the Sea of Marmara.

Özet

Bu çalışmada, Mart 2018 ile Mart 2019 tarihleri arasında, Marmara Denizi’nin Erdek kıyısında yer alan aktif bir midye çiftliğinde askılı ağlarda yetiştirilen Ostrea edulis’in büyüme ve morfometrik gelişimi incelenmiştir. Kabuk uzunluğu, kabuk genişliği, kabuk kalınlığı ve yaş ağırlık aylık olarak ölçülmüş; aynı dönemde deniz suyu sıcaklığı, tuzluluk, çözünmüş oksijen ve klorofil-a konsantrasyonu izlenmiştir. Çalışma süresince deniz suyu sıcaklığı 9,0–25,9 °C arasında, tuzluluk ise 23,8–26,2 PSU arasında değişmiştir. Ortalama kabuk uzunluğu 22,97 ± 6,48 mm’den 84,03 ± 11,16 mm’ye, ortalama yaş ağırlık ise 2,06 ± 1,82 g’dan 72,85 ± 18,97 g’a yükselmiştir. Yaşama oranı %95 olarak belirlenmiştir. En yüksek uzunluk ve ağırlığa dayalı spesifik büyüme oranları Mayıs–Haziran aralığında gözlenmiş, bunu kışa doğru kademeli bir azalma izlemiştir. Büyüme, deniz suyu sıcaklığı ile olası bir mevsimsel ilişki göstermiş; klorofil-a ile ilişkisi ise daha dolaylı kalmıştır. Bu sonuçlar, Marmara Denizi’nde aktif bir midye çiftliği ortamında O. edulis’in askılı yetiştiricilik performansına ilişkin öncü ve sahaya özgü bilgiler sunmaktadır.
