Shellfish farming Dea is a family shellfish farm, specializing in oyster and mussel farming, located in the Bay of Mali Ston on the Pelješac peninsula, in the town of Ston. What makes shellfish from this area unique in the world is the rare combination of fresh and sea water of incredible purity in which they are grown. Here you will have the opportunity to taste fresh sea oysters combined with homemade white wine — straight from the sea with a little lemon that is eaten by hand. The kind owner of the farm can tell you a lot of interesting things not only about shellfish, but also about the Mali Ston Channel and their cultivation.
