| The fish fauna and community structure at 20 stations in streams of the Mt. Biseul were investigated from June 2003 to May 2004. During the study period, 29 species, 25 genera belonging to 9 families were collected. Cyprinid fish occupied 48.3% (14 species) and cobitid fish had 13.8% (4 species). Six species (22.2%) were korean endemic and two species of Micropterus salmoides and Lepomis macrochirus were exotic. It was found that the population density of carnivorous fish (Opsariichthys uncirostris amurensis) increased in the lower-reach of small streams in the Mt. Biseul area since it had been introduced from the other native rivers in the middle 1990s. As the result of analyzing fish community in the surveyed area, the species diversity ranged from 0.553 to 1.023. The findings showed that the Geumpo, Chacheon and Hyeonpung streams had higher species diversity indicies of $0.936{sim}1.023$ than the Sincheon and Gisegok streams with $0.553{sim}0.727$. |
