在其活动范围的最南端，多莉瓦尔登，Salvelinus malma (Walbaum)，通常是不迁徙的。北海道位于其在亚洲活动范围的南部，除了两只雌雄同体的雄性（Hikita, 1962; Ishigaki, 1967）和一只未成熟雌性的幼崽（Maekawa, 1973）外，没有记录到多利瓦尔登的海跑型。有趣的是，这三个个体都是从知子半岛及其周围的河流中采集的。
At the southern extremes of its range the Dolly Varden, Salvelinus malma (Walbaum), is usually non-migratory. Hokkaido is within the southern limits of its range in Asia, and the sea-run type of the Dolly Varden has not been recorded there, with the exception of two anadromous males (Hikita, 1962; Ishigaki, 1967) and one smolt of an immature female (Maekawa, 1973). Interestingly, all three individuals were collected from rivers in and around the Shiretoko Peninsula.
