The Alaska pollock has been said to be "the largest remaining source of palatable fish in the world". Around 3 million tons of Alaska pollock are caught each year in the North Pacific, from Alaska to northern Japan. Alaska pollock is the world's second most important fish species in terms of total catch.
Alaska pollock is considered the "national fish" of Korea.
The Korean name of the fish, myeongtae (명태,明太), has also spread to some neighbouring countries.
It is called mintay (минтай) in Russia and mintaj in Poland,
and its roe is called mentaiko (明太子) in Japan.
