Cultivated off the coasts of southern Portugal and northern Spain, our mussels naturally improve the quality of the water around them as they grow, providing a model of restorative ocean aquaculture. These plump, briny-sweet morsels make fine eating—and they’re rich in protein, too.*

Mussels pack as many nutrients as large fish, with the added environmental benefits of being lower on the food chain.

A complete protein, mussels contain all the essential amino acids needed to support functions like building muscles and skin. They’re a good source of iron, which carries oxygen to the blood to help maintain your energy, and their levels of vitamin B-12, which keeps red blood cells healthy, are well off the chart.* A serving of our mussels contains as much as 1000% of the daily value of this vitamin.

Sourcing: A Coastal Harvest

Our Mediterranean mussels (Mytilus galloprovincialis) are cultivated off the coasts of Galicia, Spain and Sagres, Portugal. Both locations produce excellent mussels with a similar rich, savory flavor.


In Spain: Mussels are native to Galicia and naturally thrive there, thanks to an upwelling from the Atlantic Ocean that brings in nutrients and phytoplankton, a natural food source. Our mussels come from certified EU Organic farms in the Galician bay of Ría de Arousa.

In spring, mussel seeds (spat) are placed on 40-foot ropes and then suspended vertically from bateas, large wooden rafts. The bay keeps the salinity level at around 34%, enabling the mussels to grow faster (8-9 months versus 13 months elsewhere). Once the mussels reach maturity, local farmers haul them up to harvest. Conservas Antonio Pérez Lafuente, a regional cannery in business for well over a century, steams the mussels, causing them to shed excess liquid that would dilute the seasonings in the can. Typically this broth would be discarded, but Pérez Lafuente adds some to each can, along with Mediterranean seasonings and extra-virgin olive oil. The result is less waste and a broth so delicious you can drink it straight from the can.

In Portugal: Mussels are native to this region too. Our partners raise them three miles off the southwestern tip of the country, in deep ocean waters swept by strong currents. As in Spain, the mollusks are raised on ropes—but here the ropes drape horizontally between buoys, like underwater necklaces. Every six months or so, farmers winch up the ropes, encrusted with thousands of mussels. They sort the mussels by size, and the mature ones are washed, shelled and sent to Pérez Lafuente to be seasoned and packed the same way as our Galician mussels.
Our Portuguese farm, Finisterra, is also the first aquaculture operation in continental Europe to meet the rigorous global standards of the Aquaculture Stewardship Council (ASC).

At Finisterra, off the coast of Sagres, Portugal, workers lower "socks" of immature mussels, which they've just sorted from mature mussels, into the water. Over time, the small mussels attach to the rope running down the center. The sock disintegrates as the mussels grow to market size.

Unlike other farmed fish or animals, mussels require no inputs from the farmer—no feeds, no fertilizers, no fresh-water resources. But these humble little bivalves aren’t just a sustainable seafood option. They’re a restorative one.

Our mussels grow on ropes hanging from rafts (a), at Galicia, or strung between buoys, at Sagres. The thickly clustered ropes provide protected habitat for young fish and other ocean creatures (b), which ultimately results in a more abundant ocean. Mussels feast on a floating buffet of phytoplankton (c) and require no other food. A tiny intake siphon (d) draws water into the shell, where gills filter out the plankton along with other common elements in the water, like nitrogen and phosphorus. In excess, these two nutrients cause large algae blooms that fatally deprive other aquatic life of oxygen. So, by steadily releasing filtered water (e), mussels improve water quality for many other marine species. A single mussel can process 10 to 15 gallons of water per day.

Both in Galicia, Spain and Sagres, Portugal, our mussel operations support the communities that work the farms, strengthening tradition and building hope for the future.

In Spain: Mussel and shellfish farming have supported the Galician village of Vilanova de Arousa for decades. In the early 21st century, large canning factories started leaving Spain for countries with cheaper workforces, threatening the village’s economy and way of life. Conservas Antonio Pérez Lafuente, a family-owned canning company, decided to redouble its support of local farmers. “We decided that the only way to survive was focusing on what we had been doing for all our company history … local products, productions and lifelong traditional recipes,” says Juan Pérez Lafuente, whose family started Conservas Antonio Pérez Lafuente in 1892. The company, located not far from the rafts where the bivalves are harvested, was the first in the European Union to earn organic certification for its canned mussels.

In Portugal: Although mussels are native to Portugal’s southern tip, mussel farming only arrived in 2010, when our partner, Finisterra, established its EU Organic operation in the pristine waters there. Along with local workers from the Algarve region, Finisterra employs North African workers and provides them with a path to EU citizenship. The company is also certified by the Aquaculture Stewardship Council (ASC), which means it meets strict standards for social responsibility as well as minimal environmental impact. Those standards include providing a safe and equitable working environment for its workers, decent wages and regulated working hours.

In both Spain and Portugal, third-party supervisors oversee production of our mussels, ensuring quality and environmental protection.

In Spain, the farming of our mussels is overseen by CRAEGA, an organization created by the Spanish government to make sure that products in Galicia meet the European Union’s high organic standards. In Portugal, the supervising organization is SGS, a Geneva-based global testing, inspection and certification company.

The EU’s organic certification for aquaculture, established in 2009, sets comprehensive guidelines for mussels, including limiting the use of synthetic materials on the rafts and ropes to prevent chemical contamination; testing the waters for contaminants; and requiring mussel seed to be responsibly sourced. Mussel cultivators are also monitored to make sure that none of their methods harm other ocean or bird species. CRAEGA layers on its own requirements, like limiting the number of ropes and allowing only the native Mediterranean mussel species to be farmed in the waters of Galicia. In Portugal, SGS audits help make sure EU organic standards are met.
