Abstract	It is generally considered that Salvelinus malma miyabei which inhabits Sikaribetsu Lake in Hokkaido is a subspecies of S. m. malma. To clarify the di#erentiation level between Salvelinus m. miyabei and S. m. malma, we investigated genetic di#erences and genetic di#erentiation using protein polymorphism and isozyme mutation among groups (S. m. miyabei population, S. m. malma of the Tokachi River water system population which is close to Shikaribetsu Lake and S. m. malma of other region populations). Of ++ loci examined, the S band and a band were detected in the Hb-II locus and MDH locus respectively for the Shikaribetsu Lake population, these bands are new varieties that were not previously detected in S. m. malma. Therefore, two newly identified loci that could distinguish S. m. miyabei and S. m. malma clearly are reported. As a result of constructing a dendrogram using genetic distances (D) calculated from the allele frequency of ++ kind loci, the Tokachi River water system population (S. m. malma) and the other region populations (S. m. malma) were connected first in D *.*+1, secondly these , populations and Shikaribetsu Lake population were connected in D *.+0+. Therefore, S. m. miyabei was clearly classified as a subspecies of S. m. malma.
