At Mouettes d'Arvor, the profession of preserving has been passed from generation to generation. Here, in the last cannery of Concarneau, quality is the key word. Here, one does not derogate with the principles that have made and continue to make the reputation of the Mouettes d'Arvor: the freshness of the fish and work by hand. This concern for quality is also present at the time of the sale of each box.
