Each year, as Atlantic waters shift and temperatures rise, mackerel season begins along the coasts of Portugal, Northern Spain and France. This short but essential period marks the moment when Atlantic mackerel reaches its peak — in flavor, texture, and nutritional value.

Why Atlantic Mackerel Is So Special

Atlantic mackerel thrives in cold, nutrient-rich waters such as the Bay of Biscay, the Portuguese and French coast. During the season, the fish develops a natural fat content that gives it its signature richness and depth.

This oiliness not only enhances flavor, but also makes mackerel ideal for premium tinned seafood.

Nutritional benefits of Atlantic mackerel include:

• High levels of Omega-3 fatty acids, supporting heart and brain health

• Rich in vitamin B12 and vitamin D

• Excellent source of high-quality protein

• Contains selenium, a powerful antioxidant supporting thyroid function

A fish that nourishes both body and tradition.

Seasonality, Sustainability, and the Atlantic Cycle

In Portugal, Northern Spain and France, mackerel is fished according to strict seasonal rhythms. These cycles protect fish stocks, support marine ecosystems, and ensure optimal quality.

Many artisanal fleets continue to use low-impact fishing methods, selecting fish at the precise moment when size, fat content, and texture are ideal for preservation.

Seasonality isn’t a limitation — it’s a guarantee of excellence.
