Known simply as "la fabbrica del tonno" this tuna facility lies between Torre Colimena and Porto Cesario. Colimena applies craft production methods: the tuna is not steamed but cooked in a broth with Mediterranean herbs and natural sea salt. The tuna include albacore, bonito, Ionian little tunny, Strait of Sicily skipjack and mackerel. Agostino Lomartire and Franco Scarciglia have a list of products ranging from the tuna filets to tuna belly, tuna pasta condiments, and stuffed chillies.
