Summary:Two anadromous Dolly Varden, tagged in the Wulik River, Alaska, during September 1988, were recaptured in the Anadyr River, U.S.S.R., one in August 1989 and one in August 1990. Two additional tag recoveries were made south of the Bering Strait, one near Savoonga on St. Lawrence Island, Alaska, and one near Egavik in Norton Sound, Alaska. The greatest distance traveled was 1690 km. This is the first record of fish movement between freshwaters of Alaska and the U.S.S.R. and the longest documented movement of a Dolly Varden or Arctic char.Key words: Dolly Varden, Salvelinus malma, movements, U.S.S.R., Alaska RÉSUMÉ.
