Аннотация:Atlantic salmons, as well as Pacific salmons and trouts, were studied using electrophoretic analysis
of nuclear DNA treated with short-splitting restriction endonuclease (taxonoprint). The DNA patterns of the
species investigated can be clearly divided into four groups: (1) Salmo salar (Atlantic salmon); (2) Salmo trutta
(trout), S. trutta caspius (Caspian trout), and S. ischchan (Sevan trout); (3) Parasalmo mykiss (Kamchatka steel-
head), P. clarki (Clark’s salmon), and Kamchatka forms; (4) Oncorhynchus species (salmon trout O. masou,
chum salmon O.keta, pink salmon O. gorbuscha, sockeyed salmon O. nerka, king salmon O. tschawycha, and
coho salmon O. kisutch). It is suggested that these natural groups can be considered as taxons of the genus rank.
