| The ichthyofauna and fish community of the Gap stream water system were studied at 17 sites from March to December, 2000. It was confirmed the presence of 36 species,29 genera in 8 families. Twenty-five species in Cyprinidae was accounted for 69.4% of the total, four species in Cobitidae 11.1% of the total species number. The dominant species in the Gap stream water system was Zacco platypus (relative abundant 52.0%), the subdominant species was Carassius auratus (9.2%). The major dominant species in the each tributary of the Gap stream water system were Zacco platypus (Daejeon stream, 87.0%; Yoodeung stream, 41.5%; Gap stream, 47.5%). Number of Korean endemic species was 12 species in the Gap stream water system and that was a 24.5% of the total Korean endemic species. Ten rare species accounted for less than 0.3% of the total individual numbers. The mean species dominance, diversity and evenness indices of the fish community from the Daejeon stream were 0.76, 0.25 and 0.28, respectively: from the Yoodeong stream, 0.20, 0.65 and 0.83, respectively; from the Gap stream, 0.25, 0.83 and 0.77, respectively. The fish community of the Yoodeung stream was showed closer relationship to that of the Gap stream than to that of the Daejeon stream. |
