CONSERVERA CASTREÑA S.A. is a canned and salted fish factory, with more than 33 years of experience in the sector. His specialization has been, for many years, the manufacture of salted anchovies and anchovy fillets in olive oil. In recent years it has been incorporating another series of products into its catalog, such as canned Bonito del Norte in Olive Oil, and products made from anchovy, such as "anchovy pearls". "La Castreña, synonymous with quality" is our slogan and the principle that has governed our company since the beginning. To elaborate our products, we start with the highest quality raw material and follow a careful process of artisanal elaboration, carried out entirely in our facilities in Castro Urdiales, thus ensuring that our products are of the highest quality. All natural and without artificial additives.
