Costco's Fresh Wild Mahi Mahi Fillet is a premium seafood counter item sold by the pound, featuring whole fillets of wild-caught mahi mahi (Coryphaena hippurus), also known as dorado or dolphinfish. The fish is sourced from tropical and subtropical ocean waters and delivered fresh, never frozen, making it an excellent choice for those seeking the best possible texture and flavor.

Mahi mahi is prized for its firm, moist, and flaky white flesh with a mild, slightly sweet flavor that is far less "fishy" than many other species. The fillets are typically boneless and skinless, making preparation easy and approachable for home cooks. Its firm texture holds up exceptionally well on the grill, in a hot skillet, or in the oven — it pairs beautifully with tropical salsas, citrus marinades, blackening spices, and Asian-inspired sauces. Because it carries seasoning so well and cooks in minutes, it is a favorite for fish tacos, rice bowls, and weeknight dinners.

As a lean, wild-caught protein, mahi mahi is naturally low in fat and high in protein, making it a nutritious option for a wide range of diets.
