| The Ichthyofauna and fish community were studied in the lower course of Imjin River from April 2003 to October 2004. During the survey period 80 species belonging to 23 families were collected. Twenty-five species (31.1%) of them were Korean endemic species. Exotic fishes were Carassius cuvieri, Lepomis macrochirus and Micropterus salmoides, and they complied 1.3% of total catch. The species of Hemibarbus mylodon was identified as natural monument, and acheilognathus signifer, Pseudopungtungia tenuicorpa, Gobiobotia macrocephala and Gobiobotia brevibarba were endangered species. Migration fish were Coilia ectens, Anguilla japonica, Plecoglossus altivelis and Takifugu obscurus. Dominant species were Zacco platypus (St. 1), Microphysogobio yaluensis (St. 2), Hemibarbus labeo (St. 3, 4) and coilia ectens (St. 5). The lower course of Imjin River was more abundance of species, high diversity and richness, and lower dominance index than those of the lower course of Han River. |
