Özet
Mart 2003 ve Ağustos 2004 tarihleri arasında beş farklı istasyonda mevsimsel olarak gerçekleştirilen trol örneklemeleri ile Çandarlı Körfezi'nin balık kompozisyonu ortaya konmuştur. Örneklemeler, Türkiye sularında ticari olarak kullanılan geleneksel bir dip trol ağının, araştırma gemisi Egesüf tarafından gündüz saatlerinde çekilmesi ile yapılmıştır. Çalışma bölgesinde 33 familyaya ait olarak 11 kıkırdaklı, 49 kemikli toplam 60 balık türü tespit edilmiştir. Kemikli balıklar grubundaki türler sayı ve ağırlık bakımından baskın olarak bulunmuştur. Mullus barbatus (% 15.63), Citharus linguatula (% 13.36), Diplodus annularis (% 13.27), Serranus hepatus (% 12.28) ve Merluccius merluccius (% 10.89) türleri tüm istasyonlarda ve tüm mevsimlerde dominant olarak yaklanan türlerdir. Tüm av içinde yakalanan balıkların oranı % 89.06 iken, bunu sırasıyla sefalopod % 9.52 ve krustase % 1.42 ile takip etmiştir. III nolu istasyonda toplam 37, II nolu istasyonda toplam 36 ve IV nolu istasyonda ise toplam 35 balık türü tespit edilmiştir. İstatiksel analizlere göre, tür çeşitliliği, maksimum tür zenginliği ve Evenness Fonksiyonu sırasıyla H'= 2.950, Hmax= 4,17 ve J'= 0.715
The fish composition of five different stations in Çandarlı Bay (Aegean Sea) were studied by means of seasonal trawl surveys between March 2003 and August 2004. Samplings were carried out onboard R/V Egesuf by employing a conventional bottom trawl commercially used in Turkish waters during daylight hours. A total of 60 fish species of 49 bony and 11 cartilaginous fishes from 33 families were collected in the study area. the species of the group osteichthyes was the highest percentage in terms of number and weight. Mullus barbatus (% 15.63), Citharus linguatula (% 13.36), Diplodus annularis (% 13.27), Serranus hepatus (% 12.28) ve Merluccius merluccius (% 10.89) were determined dominant fish species during the studying period. While catched fishes’s rate of among the whole prey was 89 %, following that cephalopods are 9.52 % and crustaceans are 1.42 %. successively Total 37 fishes species in station III and total 36 fishes species in station II and also total 35 fishes species in station IV were found. According to statistical analyses, species diversity, maximum species richness and Evenness Function were computed as H'=2.950, Hmax=4.17 and J'=0.715 respectively
