Abstract
Cytogenetic studies on Bryconid fishes have shown the occurrence of ka ryotype and NOR conservatism and heterochromatin reorganization. The p resent data on three species representative of the migratory genus Bry con corroborate the hypothesis according to which conservative pattern s of karyotypic evolution can be related to high levels of vagility an d large populational size in Neotropical freshwater fishes.
