In July and August 1935, the writer was on board S. S. “Daisan-Unyômaru”, a floating factory of Taiheiyô Gyogyô Kwaisya, to make the determination of the species of Oncorhynchus caught in the region extending from 51 north latitude to the south of Cape Kronotskii. The results of detailed measurements with each one individual of each kind got in four successive fishing periods, A to D, as shown in table 1, together with some of the variations obtained with each 400 individuals, as shown in comparison with JORDANS results in Table 2, confirm that the fish, which are called (1) “Beni” or “Benizyake” by fishermen in this region, are Oncorhynchus nerka (Walbaum), (2) “Syake” or “Sake” are Oncorhynchus keta (Walbaum), (3) “Gin” or “Ginzyake” are Oncorhynchus kisutch (Walbaum), (4) “Masu” are Oncorhynchus gorbuscha (Walbaum) and (5) “Suke” are Oncorhynchus tschawytscha (Walbaum).
