Malostonski zaljev / Mali Ston Bay special marine reserve

Mali Ston Bay (Malostonski zaljev), enclosed between the Pelješac peninsula and the mainland in southern Dalmatia, was declared a Special Natural (marine) Reserve in 1983 (≈4,821 ha, from the Sreser–Duba line eastwards) and is a Natura 2000 site. It is protected primarily as a shellfish-farming ecosystem (European flat oyster and Mediterranean mussel); as a special reserve it falls under the protected-area fishing regime (NN 48/2026) where the managing institution may fully prohibit or restrict sport/recreational fishing, including spearfishing.
