Skipjack

The skipjack tuna is a perciform fish in the tuna family, Scombridae, and is the only member of the genus Katsuwonus. It is a cosmopolitan pelagic fish found in tropical and warm-temperate waters.

Skipjack is the workhorse of canned tuna, making up roughly 95% of the canned tuna catch. In Japan it's katsuo, eaten raw as sushi or sashimi, seared as katsuo tataki, or dried and smoked into katsuobushi. In Hawaii it's aku.

Skipjack tuna, Katsuwonus pelamis, is a pelagic fish of tropical and warm-temperate waters worldwide, swimming in huge surface schools. The Maldives, France, Spain, Malaysia, Sri Lanka, and Indonesia land the largest catches.
