Lingcod are neither a ling nor a cod, but with their white and flaky flesh, they have some resemblance to both of those fish. Lingcod can grow up to 60 inches and 130 pounds. They are spotted in various shades of grey, and sometimes have a blue-green flesh prior to cooking. Lingcod are unique to the west coast of North America. They live on the sea floor, mostly occupying rocky areas at depths of 32 to 328 feet. Lingcod are caught in limited quantities in the halibut and sablefish longline fisheries and are an incredibly versatile fish in the kitchen.
