Fishing permits can be obtained in any agency of the Banco Credito Agricola; the permits are $30, and are valid for one month. When going on a deep sea fishing excursion, these special permits are usually taken care of by your guide. You must have your permit and your passport with you; they must be presented if you encounter wildlife rangers at your fishing site.
