Fresh wild-caught ahi tuna (yellowfin tuna) sold by the pound at the Costco seafood counter. This premium sashimi-grade fish features a deep red color with natural marbling, indicating freshness and quality. Each package typically weighs around 2 pounds and carries a sell-by date approximately 3 days from the pack date. The tuna is sourced from wild fisheries, primarily from the Philippines and other Pacific regions.

Ahi tuna is incredibly versatile and can be enjoyed raw in sushi, sashimi, or poke bowls, or prepared as seared steaks, grilled, or broiled. For best results when cooking, avoid overcooking to preserve the tender texture and delicate flavor. The fish pairs well with sesame seeds, soy sauce, ginger, wasabi, and citrus-based marinades.
