Costco's Fresh Wild Ahi Tuna is yellowfin tuna (Thunnus albacares) sold by the pound, typically packaged as vacuum-sealed steaks weighing approximately 2 pounds per package with 2–4 steaks depending on thickness. The tuna is wild-caught, not farmed, and processed in the United States.

The fish is widely regarded as sashimi and sushi-grade quality, making it suitable for raw preparations such as poke bowls, sashimi, and sushi, as well as cooked preparations like seared ahi tuna steaks. Its mild, clean flavor and firm texture make it a versatile choice for quick weeknight seafood dinners. Packages carry a sell-by date approximately three days after the pack date and can be frozen at home to extend shelf life.
