Karyomorphology of two cyprinid barbels (Teleostei: Cyprinidae) from Gediz River, Turkey

Gaffaroğlu M., Karasu-Ayata M., Unal-Karakus S.

 




Barbus pergamonensis Karaman, 1971 and Luciobarbus lydianus (Boulenger, 1896) were studied karyologically. Karyotypes and chromosomal banding techniques with C-banding and silver staining were determined. Diploid chromosome numbers (2n) were invariably 100; karyotypes were composed of 26 metasentric (m), 20 submetacentric (sm) and 54 subtelo-acrocentric (st-a) chromosomes in B. pergamonensis and 24 m, 22 sm and 54 st-a chromosomes in L. lydianus. No heteromorphic sex chromosomes were determined. C-bands were observed on the pericentromeric regions of some of the chromosomes in the studied species. Multiple nucleolus organizer regions were detected in both species. This study shall contribute to barbels cytotaxonomy.
