In 1654 the King of Spain entrusted the management of all the tuna fisheries in Sardinia to the banker Gerolamo Vivaldi, who had largely financed the Spanish treasury, which at the time were the property of the Royal Crown.

In 1671 King Philip IV sanctioned the sale of the tuna fisheries to Gerolamo Vivaldi, who established a tuna processing plant in Portoscuso. The tuna was salted and stored in wooden barrels and then sold.

After the Unification of Italy, the then-owner Pasquale Pastorino built a new complex on the island of San Pietro: a healthier canning plant than the previous one which had to close due to malaria.

In recent history, much is owed to lawyer Salvatore Greco: a protagonist in recent years of the survival of the "tonnara fissa", the tuna fishing nets system, and consistently at the forefront of environmental battles in defence of the ecosystem.

After being caught, the tuna was placed in the shade on reed mats for drying, later put in 10kg cans and then cooked in sets of huge pots. Some of the machinery, dating back to various eras, from cookware to autoclaves, can still be seen in our plant, bearing witness to the ancient tradition.

Salvatore Greco, along with his sons Giuliano, Pierpaolo and Andrea, are working together today to ensure continuity and future for this ancient tradition of immeasurable economic-social importance for the economy of the territories where it takes place.
