| Abstract: | The migratory history of the white‐spotted charr Salvelinus leucomaenis was examined using otolith microchemical analysis. The fish migrated between freshwater and marine environments multiple times during their life history. Some white‐spotted charr used an estuarine habitat prior to smolting and repeated seaward migration within a year. |
