Mahi is expensive! Good caviar made with mahi-mahi. Europe and the United States do not have mahi-mahi, they do caviar generally use sardines, mackerel, mahi-mahi roe used to be sold ah!
Mentai fish is cod, North Korea and Japan like to eat, its meat rough firewood, roe nutritional value is far less than the roe of mahi-mahi, North Koreans use the roe of Mentai fish to make chili sauce, the price is not expensive.
