The Bay of Biscay, stretching along the northern coast of Spain and the western coast of France, is one of Europe’s most iconic maritime regions. Known for its rough, nutrient-rich waters and deep underwater canyons, this corner of the Atlantic nurtures some of the world’s finest seafood, including Bonito del Norte, hake, anchovies, and mackerel. It’s here that generations of fishermen and artisan brands have developed the timeless tradition of seafood preserves, turning the natural bounty into gourmet treasures.

Unique Conditions of the Bay of Biscay

The Bay of Biscay owes its exceptional marine life to a combination of cold Atlantic currents, nutrient-rich upwellings, and deep seafloor canyons. These conditions create ideal feeding grounds, allowing fish to grow slowly and develop firm textures and intense flavors that define premium preserves.

Fishermen along the northern Spanish coast, from Galicia to the Basque Country, and along the French Atlantic coast have mastered the challenges of these waters. The waves can be fierce, but the results are unparalleled quality, making the Bay of Biscay a sustainable and bountiful fishing ground.

Cold, Nutrient-Rich Waters

The mix of cold northern waters and warmer Atlantic currents ensures an abundance of plankton and nutrients, creating perfect growth conditions for fish like Bonito del Norte and hake.

Deep Canyons and Ocean Currents

The Bay’s underwater landscape, with its canyons and basins, provides natural habitats where fish thrive, resulting in a distinct taste and texture that are impossible to replicate elsewhere.

Sustainable Fishing Practices

Traditional, low-impact fishing methods, such as pole-and-line or hook-and-line techniques, are still widely used, ensuring high-quality, sustainable seafood for preserves.

Iconic Fish of the Bay of Biscay

Bonito del Norte – The White Tuna

Renowned for its delicate, tender flesh and perfect fat balance, Bonito del Norte is the pride of Cantabrian waters. Caught during summer using traditional techniques, it is ideal for premium canned seafood.

Hake – Silky and Delicate

The soft, mild flesh of hake is a culinary treasure. Its texture makes it perfect for preserves, delivering a gourmet experience in every tin.

Anchovies – Rich and Balanced

Small yet full of flavor, anchovies from the Bay of Biscay absorb the richness of the waters. Properly cured in salt and olive oil, they achieve a delicately balanced taste that is a hallmark of Cantabrian preserves.

Mackerel and Sardines – Oily and Flavorful

Packed with natural oils, these fish retain both flavor and nutrients when canned. Their distinctive Atlantic taste makes them essential ingredients in high-end seafood preserves.

Preserving Seafood: A Centuries-Old Tradition

The Bay of Biscay is not only rich in natural bounty—it is also a center of artisanal preservation. Local families have passed down techniques for salting, oiling, and canning fish, allowing the flavors of the sea to be enjoyed year-round.

Brands like Olasagasti, Alalunga, and Nuri continue this heritage, selecting the finest catches, cooking them with precision, and maturing them in oil or brine until they reach perfect balance. The result is a preserve that captures the very essence of the Bay of Biscay.
