Lingcod (Ophiodon elongatus) — despite the name, not a true cod — is a commercially important marine fish of the Hexagrammidae (greenlings) family, found mainly in the northeast Pacific from Alaska to Baja California and prized as a sport/game fish. Marketed fresh and frozen, it is steamed, fried, broiled, boiled, baked or microwaved; its firm, mild white flesh suits tacos, fish and chips and chowders, and its livers are particularly rich in vitamin A (historically a cod-liver-oil-like source). Rapid chilling after capture preserves quality, and fisheries are managed with size and bag limits.
