Alaska pollock
Koreans have been eating Alaska pollock since the Joseon era. One of the earliest mentions is from "Seungjeongwon ilgi" ("Journal of the Royal Secretariat"), where a 1652 entry stated: "The management administration should be strictly interrogated for bringing in pollock roe instead of cod roe." Alaska pollocks were the most commonly caught fish in Korea in 1940, when more than 270,000 tonnes were caught from the Sea of Japan (East Sea). It outnumbers the current annual consumption of Alaska pollock in South Korea, estimated at about 260,000 tonnes in 2016. Nowadays, however, Alaska pollock consumption in South Korea rely heavily on import from Russia, due to rises in sea water temperatures. In 2019, South Korea imposed a total ban on pollock fishing "to help replenish depleted stocks" of the fish.
