The Sanctuary consists of four sectors, three located  in Khasan District, Primorye, and the fourth on Popov Island, Pervomaisk District, Vladivostok. The Sanctuary is also in charge of sections of the continental coastal strip,  islands and adjacent water areas of Peter the Great Bay totaling 64,316.3 ha or 10% its area. A three- mile-wide sea zone and 500 m-wide coastal zone have been established to protect the Sanctuarys sea borders.
The total reservation zone is the largest area, including the Eastern sector (45,000 ha of water and 900 ha of land), which includes the islands Bloc Pelis, Stenin, Matveev, De Livron, Gildebrandt, Durnov, the Maximov, Vkhodnoi, Astafiev and Utiosistyi Islets, the Baklanii kekurs, the kolumnar kekur near Cape Sosnovyi and the kekurs near Bolshoi Pelis Island, the Elizarov rocks, and Gorshkov, Sredniaya, Nerpichiya, Astafieva, Spaseniya and Teliakovsky Inlets. Withdrawal and introduction of all organisms are banned here. In protection zones of Inlets Sredniya and Inlet Spaseniya, Sanctuary cordons have been built to accommodate inspectors. Occasionally researchers invited to conduct research stay at cordons Inlet Spaseniya and Inlet Sredniaya to perform their studies.
    In the Soutern Sector (15,000 ha of sea and 200 ha of land, including the islands Furugelm, Vera, the kekur Gelmersen, the rocks Bui, Yuzhnyi, Mikhelson and Butakov, Cape Ostrovok Falzhivyi, the inlets Kalevala, Sivuchiya and Pemzovaya), conventional and videocameras, research related to development of foundations for preserving and restoring marine communities, and monitoring and taking stock of the Sanctuarys population shall be allowed by special permission of management.
    In the smallest Western sector (3,000 ha of water with Sivuchyi rocks, Minonosok and Kreiserok Inlets), along with conservation of natural communities, biological foundations for growing mariculture are being developed, and by agreement with the Sanctuary the Temp Co., Ltd. Is cultivating pecten young to replenish and restore its natural populations in the Sanctuary and in other marine farms of Primorye.
    The Northern Sector designed for enlightenment and excursions occupies 216.3 ha on Popov Island with its hotel and  Sea Nature and Its Protection museum opened for education and tourist groups; also, an ecologic educational center has been organized. On Likander peninsula, an insular botanical garden is being organized to conserve the coastal zone vegetation changed in insular conditions.
    Several permanent protection cordons have been set up in the Sanctuary, and seasonal stations are operating on all islands in spring and summer. Thanks to improved protection, largha-seal  population in the Eastern and Southern Sectors has increased along with the number of gray stork families on Furugelm Island.  Again, the spawning grounds of Primorye pecten, the Far Eastern trepang  and other animals have revived along with vegetation of islands formerly serving as bases for fishermen and servicemen.
    Removal of all animals and plants, environment pollution, movement of vessels and motor transport, entry and dwelling on coast and islands shall be off limits in the Sanctuary and its protection zone. A vast buffer zone in the form of a planned Marine Park in Peter the Great Bay will play an auxiliary, yet substantial role in protecting the Sanctuary.
