Fish, asparagus, peaches and wine characterize the 4 municipalities included in the Reserve, and they play a leading role in the local economy.
An important stage of the gastronomical itinerary related to the Isonzo river's mouth is the peach, which plays a leading role in the fruit and vegetable production. It can be tasted alone, in desserts or dipped into wine, as shown by a local specialty called "Piersolada".
The fish dishes (from the sea or he lagoon) can be tasted in many restaurants, especially in Grado. The island's specialty is the "boreto a la graisana", a fish broth (European seabass, picked dogfish, tub gurnard, European flounder and turbot) with pepper served with polenta.
