Our country is one of the largest producers worldwide, with the Galician coast, the Cantabrian coast, and the Atlantic Andalusian coast standing out.

The main exports include fresh fish and seafood, frozen fish and seafood, fish fillets, dried, salted, and/or smoked fish, crustaceans, mollusks, and canned products.

Each fish (sardine, sardinella, tuna, bonito, mackerel, salmon, anchovy…), shellfish, or bivalve mollusk (mussel, clam, cockle, scallop, razor clam…) and cephalopod mollusk such as (squid, cuttlefish, octopus) has a differentiated production process.

However, we can observe a certain common pattern for all products such as washing of the raw material, packaging and canning, sealing, washing, and sterilization of the container for subsequent labeling and packaging.

The consumption of fish and seafood has increased in all its formats thanks to new healthy food trends, as they are products with high protein value and low fat content.

In addition to this, they also have other benefits such as the high Omega 3 content found in fish like salmon, sardine, mackerel, cod, herring, freshwater trout, or canned tuna in water.


Although by excellence, canned tuna products are the main product with the highest distribution and sales elaborated by the canning industry, representing almost 70% of the total fish and seafood industry.
