Description	Chromosomal polymorphism regarding the number of chromosomal NOR sites in the cyprinid fish Chondrostoma lusitanicum reported previously (Rodrigues & Collares-Pereira, 1996) was re-examined using fluorescence in situ hybridization (FISH) with a ribosomal DNA (rDNA) probe. All positive CMA3-bands contained ribosomal DNA documented by either two or four FISH positive signals in the respective karyotypes. This polymorphism suggests the occurrence of structural rearrangements of translocation type in rDNA region from one ancestral NOR-bearing chromosome pair ubiquitous among leuciscine cyprinid fishes to another pair. The absence of individuals heterozygous for this polymorphism is discussed.
