Abstract
Okyanuslarda yüzen yapılar çok sayıda ve çeşitlilikte genç ve yetişkin balıkları cezbeder. Açık denizlerde doğal ve yapay “balık cezbetme düzenekleri (FAD)”, pelajik balıkları çekme kapasiteleri nedeniyle iyi bilinmektedir. Yüzen balık kafesleri de bir çeşit FAD olarak varsayılabilir. Hatta bunlar yemlemenin etkisiyle kafes altındaki balık toplanmalarını çok daha fazla arttırırlar. Bu çalışmada, hem kuzey Ege’deki hem de güney Ege’deki altı balık çiftliği civarında doğal balık toplulukları sayılmıştır. Çipura (Sparus aurata) ve levrek (Dicentrarchus labrax) yetiştirilen her bir balık çiftliği kıyıdan 720 m ile 3 km arasında konuşlandırılmıştır. Temmuz 2015 ve Temmuz 2017 yılları arasında altı çiftliğin her birinde iki ayda bir doğal balık toplulukları sayılmıştır. Her çiftlikte SCUBA ile 11250 m3 hacmi kapsayan altı adet 5 dakikalık hızlı görsel sayım yapılmıştır. Çalışmada, özellikle en bol bulunan 3 familyayla -Sparidae (7 tür), Carangidae (6 tür) ve Mugilidae (4 tür)– birlikte toplam 22 familyaya ait 40 tür kaydedilmiştir. Bu çalışmanın sonuçlarıyla Akdeniz'in diğer bölgelerinde yapılmış çalışmaların sonuçları da birleştirilince, Akdeniz'de toplam 99 balık türünün deniz kafesleri altında toplandığı tespit edilmiştir.

Abstract
Structures, floating on the surface of the ocean attract both juvenile and adult fishes in great numbers and diversity. Natural and artificial Fish Aggregation Devices (FADs) in open seas are widely recognised for their capacity to attract pelagic fishes. It can be assumed that floating sea-cages act as a kind of FAD. Even, fish aggregations beneath the sea-cages increase much more by the influence of feeding. In this study, aggregations of wild fish were counted around six sea-cage fish farms in both northern and southern Aegean Sea. Each fish farm cultivated Sparus aurata and Dicentrarchus labrax and the farms deployed between 720 m and 3 km far from the coast. Between July 2015 and July 2017, assemblages of wild fish were counted bimonthly on two separate days at each of these farms. The Rapid Visual Counts (RVC) in five minutes with SCUBA and covering 11250 m3 were performed for six times within each farm. A total of 40 species, belonging to 22 families were recorded at fish farms, with 3 families, Sparidae (7 species), Carangidae (6 species) and Mugilidae (4 species) being particularly abundant. The results of the study and other studies conducted in other parts of the Mediterranean were merged; it was found that a total of 99 fish species were listed around sea-cage fish farms in the Mediterranean Sea.
