In the Basque Country this activity is divided into the following sub-sectors: shallow-water, deep sea-fresh water, cod fishing boats, tuna fishing-freezer boats and trawler-freezers. In the Basque Autonomous Community, the number of boats dedicated to these sub-sectors has suffered a clear drop after 1990, except in the tuna fishing-freezer boats, which has stayed the same. The most important deep-sea fishing ports are Ondarroa (Biscay) and Pasaia (Gipuzkoa). The shallow-water fishing, on the other hand, is an activity which is present in all the ports of Biscay, Gipuzkoa and Lapurdi.
