The karyotype of the dolly varden Salvelinus malma from Alaska was analysed. A pair of huge acrocentrics, which could have resulted from either tandem fusion or centric fusion followed by pericentric inversion, was observed. Ag-NORs were observed at the terminal regions of the second largest chromosome pair, and individual size-differences in Ag-NORs and in chromosomes with Ag-bands were found. From a comparison of the karyotypes of the dolly varden from Alaska and Hokkaido (Japan), karyotype differentiation by pericentric inversion and translocation was discussed.
