Farmed Fish & Aquaculture

Large-scale aquaculture has only really taken off in Spain in recent decades. The introduction of new technologies has now made fish farming a real alternative to conventional fishing. It also provides a way of counterbalancing the alarming decline in fish stocks while meeting domestic and international demand.

The farming of certain fish species, especially freshwater species and certain mollusks, has been practiced since time immemorial. Fish-farming was apparently invented by the Chinese in 2500 BC. However, there are also references to the farming of species like oysters by the ancient Egyptians and Greeks. The Romans installed both fresh and saltwater tanks in their homes to breed eels and morays, and carp, trout and other species were bred in river ponds near abbeys and monasteries during the Middle Ages.

Mollusks


Perhaps the most significant species farmed in Spain are mollusks. The most important and traditional is the mussel, which was first farmed in the Galician rias (inlets) in the 1940s. With their rich Atlantic waters, the coasts of Galicia are the ideal environment for the production of top-quality mussels. They are exported to many markets where their size and succulent orange flesh are highly appreciated.

The mussels produced by the traditional method of bateas comply with the strictest of quality controls, and are rich in protein, vitamins and minerals. One hundred grams (3½ oz) of mussels are sufficient to meet the daily protein requirements for an adult. Today, Spain is the world’s second largest producer of mussels after China. Galician mussels have a place of honor in local gastronomy and festivities, and have Protected Denomination of Origin (PDO) Mejillón de Galicia status.

Other mollusks cultivated in Galicia include oysters – also using the batea system –, as well as clams and cockles, which are cultivated in nurseries. Oysters, clams and mussels are also farmed in parts of the Mediterranean like Catalonia and, on a smaller scale, in the Balearic Islands, as well as along the southern Atlantic coast of Spain in Andalusia.

Saltwater fish


Galicia is also the focal point for the most important species of saltwater fish farmed in northern Spain: the turbot, which is produced in facilities located on land. Farming of new species like octopus, pollack and sole, is gradually starting up in this part of Spain.

Gilthead bream and sea bass are produced in the warmer waters along the Mediterranean and southern Atlantic coasts. Various systems are used – mostly floating cages – but there are also semi-extensive methods, such as those established along the coast of Cádiz, where ponds have been created on former salt pans. Bluefin tuna is also farmed in Murcia and Catalonia, eels in the Valencian Community and meager in Andalusia.

Freshwater fish


The most widely-produced freshwater fish in Spain is rainbow trout, which is extensively farmed in Galicia, followed by Castile-León and Castile-La Mancha. On a much smaller scale, other continental species such as tench are being cultivated in reservoirs and lakes in Extremadura and, to a lesser extent, in Castile-León. Sturgeon is being produced in the upper reaches of the river Guadalquivir (Sierra Nevada, Granada) and in parts of the Pyrenees in Navarre and Lleida. Additionally, there are crab farms in the Guadalquivir marshlands of Andalusia.


Aquaculture in Spain today is a modern industry made up of competitive companies using advanced technology. Their products account for about one third of Spanish fish production, guaranteeing the presence of a large number of species on our tables. There is no doubt that Spain is a nation of fish-eaters, and fish and shellfish enjoy a place of pride in Spanish cuisine, not only in coastal areas, but all over the country.
