マダラの耳石薄片法による年齢査定と成長様式
Using the sectioning of the otoliths of Pacific cod (Gadus macrocephalus), age determination was made for a total of 1, 076 individuals collected in adjacent regions of north Japan (off the southern coast of Hokkaido, the Musashi-Tai region, off Kinkasan, and the Matsumae-Kojima-Tai region) as well...

Using the sectioning of the otoliths of Pacific cod (Gadus macrocephalus), age determination was made for a total of 1, 076 individuals collected in adjacent regions of north Japan (off the southern coast of Hokkaido, the Musashi-Tai region, off Kinkasan, and the Matsumae-Kojima-Tai region) as well as off the Kamchatka Peninsula.
