Kampachi is a member of the amberjack family of finfish (also called an Almaco Jack) and often used in sushi restaurants
Amberjack is an Atlantic and Pacific fish in the genus Seriola of the family Carangidae.
They are a game fish, most often found in the warmer parts of the ocean.
Kanpachi has a distinctly fresh, sweet flavor, and firm texture. The light pink, translucent flesh excels in sashimi presentations, and the clean, rich taste shines through when cooked.
Kanpachi is one of the largest shiromi fish and is related to buri and hiramasa.
Indeed, this fish can grow to six feet in length and can weigh up to 150 pounds, although specimens that are best suited to sushi are much smaller and usually weigh no more than six pounds.
The English terms for Hamachi and Kanpachi are “yellowtail” and “amberjack”, respectively, but because yellowtail can also be called “Japanese amberjack”, overseas sushi diners sometimes think they’re the same fish. … “Amberjack” or “Kanpachi” is the species Seriola dumerili, which is less fatty.
