A fresh, ready-to-eat sashimi tray featuring two premium Hawaiian fish: Ahi (yellowfin tuna) and Au (Pacific marlin), both prized for their clean flavor and firm texture. Prepared in-store at Costco's service deli and sold by the pound, this tray is a staple of Costco's Hawaii-region seafood counter.

The fish is hand-cut and packaged fresh the same day for optimal quality. Both Ahi and Au are traditional Hawaiian sashimi fish — Ahi delivers a rich, mild tuna flavor, while Au (marlin) offers a slightly firmer, mildly sweet taste. The tray is ideal for sashimi presentations, poke bowls, or pairing with soy sauce, wasabi, and pickled ginger.

As a fresh product sold by weight, availability, cut size, and ratio of Ahi to Au may vary by location and day.
