Abstract	The chromosomal complement of Cobitis taenia was analysed by replication banding techniques to determine whether there were specific patterns that could allow distinction of the different chromosomes. The diploid chromosome number of 2n = 48 is diagnostic of this species. In vivo 5-bromodeoxyuridine (5-BrdU) incorporation induced highly reproducible replication bands. Most of the chromosome pairs were distinguishable on the base of their banding patterns. The karyotype, consisting of five pairs of metacentrics, nine pairs of submetacentrics and 10 pairs of subtelocentrics and acrocentrics, was confirmed. C-banding and replication banding patterns were compared, and heterochromatin was both early and later replicating. C-positive heterochromatin in centromeric regions was mainly early replicating, but that located in pericentromeric regions was late replicating. Most of the late-replicating regions found interstitially were C-band negative. The results obtained so far for combined chromosomal staining methods of C. taenia and other Cobitis fish species are discussed.
