The karyotype and major ribosomal sites as revealed by silver staining and CMA(3)-fluorescence of Croatian leuciscine cyprinid endemic to Cetina River, Telestes ukliva were studied. The diploid chromosome number was invariably 2n = 50. Karyotype consisted of eight pairs of metacentric, 13 pairs of submetacentric and four pairs subtelocentric chromosomes. The largest chromosome pair of the complement was subtelocentric, which is a characteristic cytotaxonomic marker for all representatives of the cyprinid lineage Leuciscinae. The nucleolar organizer regions (NORs) were detected in the telomeres of two pairs of medium-sized submetacentric chromosomes. Staining with CMA(3) revealed four positive signals that corresponded to NOR sites. No heteromorphic sex chromosomes were found.
