- Аннотация: waters of Kamchatka peninsula, in the Russian Far East, are dominated by fishes in the family Salmonidae. Until recently, it was assumed that all of the trout in Kamchatka are coastal rainbow trout (Oncorhynhcus mykiss mykiss), indistinguisable from Notrh American coastal rainbow trout (O. m. irideus). A form of trout was collected in 1994 in the Tigil River basin of Northwestern Kamchatka with a unique spotting pattern, a cutthroat mark on the lower jaw and basibranchial teeth: all characters associated with redband rainbow (O. m. gairdneri) of cutthroat trout (O. clarki). In 1996, additional specimens were collected with these characteristics from the Sedonka River, a tributary of the Tigil River. Morphological analysis of approximately 80 specimens collected in different years finds a series of phenotypically diverse forms. While precise phylogenetic position of these various forms remains unclear, genetic analysis to date aligns these trout with the rainbow trout lineage.
