Pacific saury or Mackerel pike. The Pacific saury, Cololabis saira, is a saury, a member of the family Scomberesocidae. This fish, which is a food source in some East Asian cuisines, is also known by the name mackerel pike.
The term saira used in its scientific name is the fish’s local name in the Kii Peninsula region of Japan.
The Chinese characters used in the Chinese and Japanese names of the fish (秋刀魚) mean “autumn knife fish,” in reference to its body-shape, somewhat resembling a knife, and its peak season.
