BayMar Canned Seafood: Cockles, Mussels, and Seafood from Galicia

BayMar is a brand of canned Galician seafood that has gained visibility in recent years among buyers of gourmet seafood products. Its positioning in the premium segment of Galician canned foods, with a special emphasis on cockles and mussels from the Rias Baixas, has allowed them to build a loyal customer base who value the quality of Galician seafood preserved with attention to detail.

This guide explains what BayMar offers, how it positions itself in the market, and how it compares to other options for those seeking quality canned seafood in Spain.

Who is BayMar Canned Seafood

Updated March 2026. After decades working with seafood products, we have learned that quality makes a difference.

BayMar is a canned seafood company based in Galicia, specializing in products from the Galician Rías. They work with local shellfish gatherers and producers to access cockles, mussels, clams, and other shellfish from the rías at their peak quality, and they process and preserve them with the aim of maintaining the organoleptic characteristics of the fresh product in a long-lasting format.

Their positioning is that of superior quality artisanal canned goods, aimed at a consumer who is no longer content with low-priced industrial seafood but also doesn't necessarily want to pay the highest prices on the market. It is a proposition of real quality at a reasonable price within the premium segment of Galician canned foods.

BayMar's main catalog

Cockles from the Galician Rías

BayMar's best-known product. Their cockles come from the Galician Rías Baixas, with a selection of sizes that prioritize large pieces. Galician cockles have a well-deserved international reputation: the specific conditions of the rías — the Atlantic upwelling, the concentration of phytoplankton, the cold and clean waters — produce bivalves with an organoleptic quality not easily found in other regions of the world.

BayMar offers its cockles primarily in their natural form, preserved in their own juice or with a minimal addition of sea salt. The sizes most requested by their customers are 35/45 pieces per 100g (large pieces), although they have several sizes available.

Mussels from the Rías

Mussels from the Galician Rías (Mytilus galloprovincialis) cultivated on rafts are another pillar of BayMar's catalog. They offer mussels in different preparations: natural, in escabeche (their best-selling version), and in some seasons with other marinades. Galician escabeche mussels are one of the classics of Spanish canneries, and BayMar prepares them with quality paprika and a balance of acidity that allows the mussel's flavor to take center stage over the seasoning.

Other seasonal seafood

Depending on the availability of the Galician harvest, BayMar may offer scallops, clams, razor clams, and other shellfish from the rías. The availability of these products is seasonal and dependent on the extraction quotas regulated by the Xunta de Galicia. When available, they usually have higher demand than supply, reflecting the reputation of Galician seafood among specialized buyers.

The process behind canned seafood

To understand why some canned seafood costs €3 and others cost €12 for the same quantity, it is useful to understand what happens between the ría and the can.

Extraction and market. Cockles are extracted by hand by permitted shellfish gatherers, with controlled daily quotas. They arrive at the market the same day of extraction. The best canneries buy the best batches at the market, prioritizing size and freshness. Industrial canneries buy what's left.

Purification. All shellfish go through a purification plant that guarantees cleanliness and compliance with health regulations. The duration and conditions of purification affect the final result.

Cooking and opening. The shellfish are briefly cooked to open their shells. The temperature and cooking time are critical: too much destroys texture and flavor; too little leaves the product raw and can cause food safety problems. Quality canneries control this process with great precision.

Packaging. The pieces are packaged by hand, selecting and placing those that exceed the minimum size. The covering liquid (own juice, seawater, oil, or escabeche depending on the variety) is added in the appropriate proportion, and the can is sealed.

Sterilization. The sealed can passes through an autoclave where it is sterilized at high temperature for the time necessary to ensure preservation. This phase determines the product's long-term durability.

In this process, every decision — the initial selection of shellfish, the cooking temperature, the packing time, the quality of the covering liquid — accumulates differences that separate a mediocre preserve from an exceptional one. This explains the price differential.

Comparison: BayMar vs Bacalalo in canned seafood

Seafood from the Galician Rías: the benchmark everyone imitates

The Galician Rías (mainly the Rías Baixas: Vigo, Pontevedra, Arousa, and Muros-Noia) produce approximately 40% of the mussels consumed in Europe and have the most regulated and productive cockle and clam beds on the continent.

The production volume is one of the reasons why Galicia can supply the demand for premium seafood, both fresh and canned. But quality doesn't come from volume: it comes from the ecosystem. The Galician coastal upwelling is one of the most powerful in the world in the European North Atlantic, bringing nutrients from the bottom to the surface continuously, creating a concentration of phytoplankton that makes Galician seafood an exceptional case of natural quality.

When you buy Galician cockles from a reputable cannery like BayMar or those we select at Bacalalo, you are not buying a product with a name of origin without real foundation: you are buying the result of one of the most productive and well-cared for marine ecosystems in the world.

Frequently Asked Questions

What is the difference between natural cockles and escabeche cockles?
Natural cockles are preserved in their own juice or with salt, without additional seasoning. The flavor is that of pure seafood, cleaner and more direct. Escabeche cockles have a marinade with vinegar, oil, paprika, and spices. The flavor is more complex and seasoned, but the seafood flavor is more masked by the dressing. To appreciate the quality of the cockle itself, the natural version is the best option.

What is the "O" in cockle sizes?
Cockle size is generally indicated by the number of pieces per 100g or per can. Some producers also use size categories (large, extra, etc.). Sizes with fewer pieces per can (35/45 vs 70/90) indicate larger pieces. Size affects the price because the larger the size, the fewer pieces per can and the more selective the sourcing.

Are mussels from Galicia better than those from other places?
In terms of international comparison, yes. Galician mussels (Mytilus galloprovincialis) cultivated on rafts in the Rías Baixas have internationally recognized organoleptic characteristics that are superior to those of mussels produced in other areas of Europe or outside the continent. The main reason is the ecosystem: the high concentration of phytoplankton and the water quality of the rías produce mussels of larger size, more abundant meat, and richer flavor.

How many cans of cockles are needed for an appetizer?
For an appetizer for 4 people as part of a seafood platter, 2-3 cans of 35/45 size are sufficient. If cockles are the only appetizer, estimate between 1.5 and 2 cans per person. Cockles are served at room temperature with the juice from the can and optionally a few drops of lemon or some fresh chopped parsley.

Do canned seafood contain glutamate or other enhancers?
Quality artisanal canned seafood does not need flavor enhancers: the flavor of Galician seafood is intense enough. Always check the labeling, but premium references from producers like BayMar and those selected by Bacalalo usually have very simple ingredients: seafood, seawater or brine, and sometimes oil or vinegar in seasoned versions.
