This small, schooling fish has the satisfying, meaty texture and mild flavor typical of big fish, along with a mighty list of nutrients. Atlantics live lower on the food chain, have short lifespans and reproduce quickly, making them more sustainable than larger, longer-lived fish. Ours are responsibly harvested off the coast of northern Spain, using hook and line, with little to no bycatch.

Fast Facts About Atlantic Mackerel

  • Our Atlantic mackerel are harvested by Spanish boats fishing in the Bay of Biscay.
  • Atlantic mackerel are beautiful fish, slender and shimmery, with tigerlike markings in blue, green and black. They average 12 inches in length and weigh about 2 pounds.
  • Benefits of eating Atlantic mackerel:
    • Mild, meaty flavor—these mackerel are very good to eat
    • Versatility in recipes (use as a sub for tuna)
    • No high levels of toxins common in larger fish
    • Nutritious: very high in protein, vitamin B-12 and other nutrients. 130 - 230 mg of omega-3 fatty acids per label serving
    • Supports family fishing boats and centuries-old local fishing associations

Nutrition: Small but Mighty

Atlantic mackerel may be little fish, but they’re packed with vital nutrients that have multiple health benefits. Also, Atlantic mackerel don’t have the high levels of toxins often found in larger predator fish like tuna and swordfish, making them safer to eat.

Each can of our Atlantic mackerel contains around 20 grams of protein (40 to 42% of the daily value) and is an excellent source of vitamin B-12, selenium, vitamin E and niacin.* Atlantic mackerel are low on the food chain, feeding on zooplankton, so they don’t accumulate toxins in the way that higher-level apex predators can over the course of their longer lives. Because toxins are passed up the food chain, they become more concentrated as animals eat and then are eaten in turn. *See nutrition information for total fat, saturated fat and sodium content.for total fat, saturated fat and sodium content.

Atlantic Mackerel Sourcing: A Delicacy from Spain

Our Atlantic mackerel comes from the Bay of Biscay, in northern Spain, where the fish school prolifically and are caught using techniques that have been passed down for generations.

Before dawn during mackerel season in spring, when the weather is often moody and unpredictable, small boats set off in search of mackerel. When they encounter the dense, swirling schools of fish, they cast out their lines, each set with up to 30 hooks wrapped in red wool to look like the tiny crustaceans that entice mackerel to bite. This method requires no baitfish, results in little to no bycatch, and produces better-quality fish, since mackerel are never crushed at the bottom of a net. The mackerel are taken to Conservas Antonio Pérez Lafuente, a regional cannery, where they’re lightly seasoned and packed in extra-virgin olive oil.

Enviro: Small Fish, Big Impact

Eating Atlantic mackerel takes pressure off larger, overfished species like tuna. This allows the less abundant fish stocks to recover.

“Forage fish—such as mackerel, sardines and anchovies—are low in the food chain,” says Tatiana Lodder, Seafood Assessor for Good Fish Foundation, an organization dedicated to fish conservation. “There’s a lot of biomass and they’re much more resilient than the larger, higher trophic species.” The Good Fish Foundation carefully assesses our mackerel stock to ensure there’s plenty left—for us and for other species that depend on them for food.

History: The Fishing Guilds of Cantabria

In the ancient villages along the Bay of Biscay, in northern Spain, fishermen and processors work together to ensure a healthy future for fish and community alike.

All along the densely forested, mountainous coastline of Cantabria, small boats head out to sea, owned by families who have fished these waters for centuries. In this autonomous region of Spain, the fishermen who harvest our anchovies and Atlantic mackerel belong to traditional cofradías, or guilds, which date back to medieval times. The guilds share profits and best practices, and ensure worker safety. They’re also social institutions, with their own bars and festivals. This tradition of cooperation, with membership handed down through generations, creates a deep sense of responsibility to protect ocean resources, and the communities that depend on them, for the future.

Partners: Guided by Science

We work with Good Fish Foundation, of Veenendaal, the Netherlands, to ensure that Bay of Biscay mackerel, as harvested by the Cantabrian fleet, remain a truly renewable resource.

As one of the few food companies that works in direct partnership with fish conservation and science organizations, our goal is to find solutions that protect, rather than deplete, our home planet. Good Fish evaluates the sustainability of fisheries in Europe and works with fishermen, fish farmers, processors and retailers to help seafood buyers make environmentally sound decisions about what to eat. The group also publishes a sustainable seafood guide for consumers and advises chefs.

Pair our canned Atlantic mackerel with crackers, toast, salads, sandwiches, grains and pastas for an instant boost of flavor and nutrition. Once you crack open a can, you’ll find that the mackerel is as versatile as canned tuna—maybe even more so, because it’s milder and meatier. Some of our favorite Atlantic mackerel recipes: a Mackerel Melt sandwich, layered with crunchy dill pickles; a party-worthy Lemon Caper Mackerel pasta; and a main-course Mackerel Niçoise salad.
