By the results of tagging experiments of chum salmon carried out in 3 years from 1935 to 1937 at the 21 fishing bases in Russian territory by Nichiro Fisheries Co., next presumptions relative to the movement in the coastal waters are added.
(1) Along the coasts of Kamchatka River, Nachigin and Kholyulin regions, chum salmon has a tendency to migrates northward, along those of Em-Et. Lovrofa and Olyutorskii, it migrates south westwards.
(2) On the west coast of Kamchtka, much migrate northerly, and few southerly. In Okhotsk region westerly. Also we may draw out next conclusion from the results of tagging experiments carried in the offing of south eastern Kamchatka during the past 5 years from 1936 to 1941 by Taiheiyo Fisheries Co. Among the chums liberated in the offing of East coast of South Kamchatka, it is likely that 20% of run northwards and 50% southwards irrespective of season.
