| Dokdo is a volcanic island, and its formative geological age took place at the end of the Pliocene Epoch. Dokdo is located at 131。 52′33" East longitude, and 37$^{circ}$ 14′18" North latitude, and is consituted of 87 islands. The total area of Dokdo is 0.186 $ extrm{km}^2$ and the length of its coastline is 4 km. Ookdo is a treasury of fish resources where many varieties of fish including squid and Alaska pollack live in abundance of greatest importance. Dokdo is a forward fishery base. Ullung island is located at 37$^{circ}$ 27′~37$^{circ}$ 33′North latitude and 130$^{circ}$ 47′~130$^{circ}$ 56′East longitude. The area of Ullung is 72.92 $ extrm{km}^2$ and the length of its seashore is 44.21 $ extrm{km}^2$. The total marine product of Ullungdo(1995) is 9,066 tons (M/T). The largest is squid, 8,900 tons. For the sea area of the depths near the Ullungdo, coast, that of 50m or less is 2,477 ha, and that of 50- 100m is 1,471ha. This fact tells us that there is no extensive area of a very shallow sea, and that it is directly connected to the deep sea. Ullungdo is a treasury of marine bioresources with rich and varied fishes including squid and Alaska Pollack and many others. Presently there is a sovereignty dispute over Dokdo between Korea and Japan. Since A.D.512, Dokdo has been a part of territory of Korea. Dokdo is a part of Kyungsang-Bukdo, Ullung-gun, Ullung-up, Do-dong in the Korean administrative district division system. Japan strenuously claims sovereignty for significant economic reasons, including fishery rights, and has adhered to a contradictory position that "Dokdo is Japanese land" since Japan incorporated Dokdo into Japanese territory in 1905.ritory in 1905. |
