Where It Grows

Mackerel are saltwater fish that are found in both temperate and tropical seas across the globe. They are pelagic species which means they reside in the open ocean, but they can also be found closer to shore in shallow, coastal waters. Mackerel are highly migratory, often moving in large schools along coastlines. They are known to prefer cooler waters, which is why they migrate to different areas depending on the seasons. Major producers of mackerel include Norway, Japan, the United States (primarily New England), and the United Kingdom.

Best Way to Eat

Mackerel can be eaten in a variety of ways, but it is most nutritious when consumed grilled, baked, or broiled to maintain its high omega-3 fatty acid content. These fatty acids are essential for heart health and brain function. Mackerel is also often consumed smoked or canned, which are convenient but may contain higher levels of sodium. When preparing mackerel, it's recommended to include a squeeze of lemon or other citrus to complement the fish's rich, oily flavor. To maximize nutrition, pair mackerel with a variety of colorful vegetables or whole grains.
