Аннотация:The meristic characters of malma, Salvelinus malma, within its range from the Chukotski Peninsula to the Southern Kuril Islands were examined. A clinal variation of the numbers of scales in the lateral line and vertebrae number was observed. With consideration of these characters, the most distinct differences were revealed between the populations of the Kamchatka Peninsula and those of the northern Kuril Islands. A break in the clinal variation of the merictic characters was observed in the region between the Kamchatka Peninsula and the nothern Kuril Islands. This region coincides with the northern limit of distribution of the southern subspecies of malma S. malma krascheninnikovi. The charrs of the northern Kuril Islands were related to this subspicies.
