초록

Fish surveys were conducted near artificial structures installed in nine streamsflowing from the Han River region to the east coast of Korea. As a result of thesurvey, a total of 33,488 individuals belonging to 11 orders, 16 families, and 48species were found. The dominant and subdominant species were Zacco koreanus,and Zacco platypus respectively. Among the surveyed fish species, endangeredspecies (rank II) were Pungitius sinensis, Ladislavia taczanowskii, Phoxinus phoxinus,Lethenteron japonicus and Cottus hangiongensis. In addition, migratory fish specieswere Pungitius sinensis, Gymnogobius urotaenia, Tribolodon brandti, Oncorhynchusmasou masou, Oncorhynchus keta, Plecoglossus altivelis, Lethenteron japonicus,Cottus hangiongensis and Tribolodon hakonensis. As a result of community analysis,Samcheokosip Stream, and Yangyangnamdae Stream have the highest diversity,and dominance indices respectively. Also, Jusu Stream has the highest richness andevenness indices. The highest number of species was surveyed in GangneungnamdaeStream (24 species). Alpha diversity (the number of species at each survey pointin each stream) was the highest at a survey point in Gangneungnamdae Stream(21 species), and beta diversity (species at each stream survey point that doesnot overlap with nearby survey point) was the highest at survey points inGangneungnamdae Stream and Jusu Stream (10 species). As a result of the similarityanalysis, surveyed streams were divided into five groups: group 1 stream (Yeongok·Samcheokosip·Gagok), group 2 stream (Yangyangnamdae·Hosan), group 3 stream(Gangneungnamdae), group 4 stream (Sangun·Jusu), and group 5 stream (Nakpung).
This study is expected to serve as basic data for managing the aquatic ecosystem ofstreams flowing from the Han River region to the east coast.
