摘要：
The growth rate of 16 juvenile chum salmon Oncorhynchus keta (180-286mm fork length) captured in the Sea of Okhotsk offshore during autumn 2002 was estimated using daily-incremental analysis of otoliths. The specimens originated from Hokkaido, Japan, and Sakhalin and Kamchatka, Russia. The average (range) of estimated mean daily growth in fork length was 1.19 (1.02-1.54)mm/day through the entire early ocean life and 1.05 (0.84-1.21) mm/day during the first 30days after sea entry. These growth rates were higher than those reported previously for coastal resident or migrant juvenile chum salmon along the coast of Japan.
