Drum fish are a family of large-bodied saltwater fish (Sciaenidae) found along the Atlantic and Gulf Coasts of the United States, named for the drumming sound some species make by vibrating their swim bladder. "Drum" and "croaker" are related common names within the same family rather than strict synonyms; black drum specifically is sometimes called "hardhead."
Market drum typically runs 2-3 pounds, though the fish can grow much larger. The flesh is firm, flaky, and mild, similar to trout or snapper, and holds up well to baking, grilling, pan-frying, and stewing. Drum is common in Cajun and Creole seafood gumbo and in Southern fish fries, where fillets are coated in a cornmeal or flour batter and deep-fried.
Drum species are also found outside the U.S. Atlantic and Gulf, including in the Mediterranean and Pacific, though the specific species and culinary use vary by region.
