Appearance patterns of freshwater fish were investigated in the western Demilitarized Zone (DMZ)
adjacent areas near Imjin River in Gyeonggi-do, Korea, of 2014. A total of 61 species belonging to 14 families
were found in the river during the survey. The dominant and subdominant species were Zacco platypus
(Relative abundance, 20.3%) and Zacco koreanus (12.6%), respectively. Other abundant species include
Rhinogobius brunneus (9.2%), Pungtungia herzi (4.4%), Acheilognathus yamatsutae (4.4%), and Pseudogobio
esocinus (4.0%). Among the residing species, 24 species (39.3%) were endemic to Korea; and 1 species,
Carassius cuvieri, was non-indigenous species. Hemibarbus mylodon is a natural monument, and Lethenteron
reissneri, Acheilognathus signifer, Pseudopungtungia tenuicorpa, Gobiobotia brevibarba, G. macrocephala,
and G. naktongensis are endangered species in Korea. In addition, Anguilla japonica and Plecoglossus altivelis
are catadromous and amphidromous species, respectively. Among the investigated sites, the lower part of
Sami Stream (St. 5, 6) and Gunnarm-dam region (St. 11, 14) are particularly valuable for the conservation of
species diversity, because many fish species (33~42 species) including a natural monument and several
endangered species inhabit in these regions.
