Conservas Olasagasti - Traditional Basque Fish Canned Goods

Conservas Olasagasti is a family-run company steeped in tradition, with over 130 years of history dating back to the late 19th century. The story begins with Salvatore Orlando, a Sicilian who settled in Getaria (Gipuzkoa) in the Spanish Basque Country and married a Basque woman named Simona Olasagasti. In 1920, Salvatore Orlando founded one of the first salted fish factories and established himself as one of the leading producers of Cantabrian anchovies. He was one of the Italian pioneers who introduced the centuries-old salt preservation techniques to the Cantabrian coast.

The company specializes in the production of top-quality canned and semi-preserved products, particularly Bonito del Norte (white tuna), anchovy fillets, bluefin tuna, and Cantabrian mackerel, all caught using environmentally friendly fishing methods and processed by hand. Key products include Bonito del Norte in various preparations, Cantabrian anchovies (considered among the best anchovies in the world), and tuna and mackerel fillets in organic olive oil.

The company continues to follow the traditional, artisanal methods of fish preservation that have been passed down since the 1920s. The fish are caught during the main season, from the end of March to the beginning of June, using small fishing boats in the Cantabrian Sea near San Sebastián. Today, the company is run by the fourth generation, Matteo Orlando, and represents the perfect combination of sustainable fishing, centuries-old Italian expertise, and Basque tradition.

Bonito del Norte - Premium White Tuna from the Cantabrian Sea

The Cantabrian Sea off the northern coast of Spain is considered one of Europe's most valuable fishing grounds for high-quality tuna. Here, in the nutrient-rich waters of the Bay of Biscay, thrives one of the world's most sought-after tuna species: the Bonito del Norte (Thunnus alalunga), also known as albacore or longfin tuna.
Biological characteristics and quality standards
The Bonito del Norte reaches an average length of 60 to 80 centimeters and weighs between 4 and 12 kilograms. Its characteristic spindle-shaped body with well-developed dorsal and pectoral fins, as well as its silver coloration with a white belly, allow for clear identification. The flesh is distinguished by its particularly tender texture and mild, delicate flavor, which clearly sets it apart from other tuna species.

Nutritional properties

Bonito del Norte is an excellent source of high-quality protein containing all essential amino acids. Its high content of omega-3 fatty acids, especially EPA and DHA, supports cardiovascular health and brain function. Furthermore, it provides significant amounts of vitamin B12, niacin, and selenium, while its low fat content makes it an ideal component of a balanced diet.

Sustainable fishing methods

The Bonito del Norte is fished exclusively during its seasonal migration between June and November. Traditional fishing methods such as selective purse seine fishing and pole fishing ensure both the sustainability of the stocks and optimal product quality. These controlled fishing practices comply with strict EU guidelines for sustainable fishing.

Processing quality and product variety

The fish are processed immediately after being caught, under strict hygiene standards. Hand-selected fillets, preserved in high-quality olive oil, are particularly prized. The ventresca, the belly section of the fish, is considered a premium product due to its exceptional tenderness and intense flavor.

Culinary applications

In professional gastronomy, Bonito del Norte is used in both traditional regional dishes and modern international cuisine. Its versatility is evident in applications ranging from classic Spanish preparations to contemporary creations such as sashimi and ceviche, where its natural qualities are showcased to their best advantage.

Market position and quality assurance

Bonito del Norte from the Cantabrian Sea represents the premium segment of the European tuna market. Strict quality controls and traceability from catch to final product ensure consistently high standards. The combination of sustainable fishing, traditional processing, and exceptional product quality makes it a preferred raw material for discerning consumers and restaurants.
