King Mackerel

King Mackerel

EverydayRaw

King mackerel is a large, migratory saltwater fish known for its firm texture and rich omega-3 fatty acid content. This predatory species, found in the Atlantic Ocean and Gulf of Mexico, contains significantly higher mercury levels than smaller mackerel varieties like Spanish or Atlantic mackerel, warranting consumption moderation per FDA guidelines. While prized for grilling and smoking, its strong flavor profile and dense flesh distinguish it from milder white fish options.
