This sampling revealed 4676 specimens from species of Alburnus istanbulensis, Barbus escherichii, Carassius gibelio, Gobio sakaryaensis, Petroleuciscus borysthenicus, Phoxinus strandjae, Rhodeus amarus, Squalius pursakensis, Vimba vimba, Neogobius gymnotrachelus, N. melanostomus, Proterorhinus semilunaris belonging to families of Cobitidae, Cyprinidae and Gobiidae. Cyprinidae family was the dominant with 94.2%, Gobiidae was 4.8% and Cobitidae was 1%. The Cyprinidae family had the highest number of species (9 species). R. amarus and S. pursakensis were found in all sampled stations. This study is the first to identify this fish fauna in the Darlık Stream and its tributaries.  CR - Albay, M. & Akçaalan, R. 2003.
