Abstract
Çalışmada Tilapia türlerinin yayılım alanlarını içeren Çukurova ve Hatay Bölgeleri'ndeki nehir, göl ve su ürünleri yetiştiricilik istasyonlarından dört tilapia türü Oreochromis aureus, Oreochromis niloticus, Tilapia zillii ve Tilapia rendalli örnekleri toplanmıştır. Tilapiaların morfolojik ayrımında morfometrik ve meristik karakterler kullanılmıştır. Morfometrik karakterlerin kümelerarası korelyon analizinde sadece Çukurova Üniversitesi (ÇÜ) O. aureus örneği belirgin bir şekilde ayrılık göstermiş diğer türler ise birbiri üzerine kümelenmiştir. Meristik karekterier bakımından ise genel olarak türler ve türlere ait populasyonlar belirgin bir ayrılık göstermiştir. Fakat T. rendalli, O. niloticus ye O. auratus ÇÜ örnekleri birbiri üzerine kümeleşerek bir farklılık göstermemiştir.
Morphologic identification of tilapia (Chiclidae) species found in Çukurova And Hatay Regions In this study, four species of Tilapia Oreochromis aureus, 0. niloticus, Tilapia zillii and T. rendalli were collected from distributional range comprising lakes, rivers and Aquaculture research centers in Çukurova and Hatay regions. Morphometric and meristic characters were used for morphologic identification. Discriminant fuction anaiysis of morphometric characters revealed clear morphometric discreteness of Çukurova University (ÇÜ) 0. aureus sample, and other specieas were overlapped together, in meristic characters, species and populations were clearly separated from each other. However T. rendalli, 0. niloticus and 0. auratus from ÇÜ samples were overlapped together and showed no meristic differences. Principal component anaiysis revealed that giil rakers and anal fin rays were important key characters to discriminate species.
