The military demarcation line (MDL), which is called as 38th parallel in Korean, has been a matter of common interest in the world since the end of Korean War in 1953. Many international scientists have discussed on an ecological importance in the demilitarized zone (DMZ) because the area comprises 2km southern and northern part from the MDL has been secured for a long time. The Pyeounghwa Dam located at 10km lower than the MDL was constructed in 1988, and extension work (Dam height: 80 to 125m) was done in 2005 in order to control primarily flood. We investigated fish community in the lower reach of the DMZ, North Han River, and found 41 species contain 4 endangered species. Among them, Korean endemic species was 18 species (43.9%) which was much greater than mean value (25.9%, Kim 1995). The fish fauna indicated that the area had high biodiversity and good habitats for those endangered species. Especially two endangered species, Hemibarbus mylodon and Siniperca scherzeri (Albino type) are classified as natural monument species, and they are protected by government law. Therefore, it is important to monitor and conserve their population and habitats in future |
