🔍 3. Ecology & Behavior

Adults feed on fishes, octopuses, and large bottom crustaceans, and move to spawning grounds at depths of 100–250 m between late summer and midwinter to spawn once a year.

🇰🇷 4. Connection to Korea

It is listed on the National List of Species of Korea (National Institute of Biological Resources (NIBR)), and Korea's National Institute of Fisheries Science revealed through biologging that Pacific cod stay at the Jinhae Bay spawning grounds for up to 15–16 days, and up to 7 days in the main spawning area.
