Since the settlement, the locals have been fishing because of its location on the Gulf of Trieste. While tuna and sardines used to be caught and processed, today the anchovies from Barcola ("Sardoni barcolani") are particularly in demand. These fish, which only appear at Sirocco, are in demand because of their particularly fine taste and achieve the highest prices. The fish larvae begin their growth in rivers such as the Po, later continue to mature in the central Adriatic, and then arrive as popular annual fish in the waters off Barcola in May or June.
