Inhabitant patterns of the legally protected species and the characteristics of fish fauna in the Pyeongchang River, Korea, were studied from April to July 2004 by selecting 6 sites. The number of fish samples in this period were 2,448 in 35 species of 9 families. A total of nineteen endemic species (54.29%) were presented and those were Hemibarbus mylodon and Acheilognathus signifer. The highest frequency was shown in Zacco korean us (34.84%) and Pungtungia herzi (10.25%) and Coreoleuciscus splendidus (6.86%) were the next. In addition, The highest biomass was found in Z. koreanus (5,580.2g) and Coreoperca. herzi (1.241.2g) and C. splendidus (1,207.0g) were the next. When comparing the distribution of the legally protected species in within the Han River system, the highesting distributions were determined in the Pyeongchang and Dong River (6 species). The ratio of individuals in the Pyeongchang River was shown to be higher (10.62%) than that of other lakes and streams. In conclusion, more precise protection and protective plans were needed in order to maintain the lake ecology in good status because the Pyeongchang River is relatively well protected from the anthropogenic disturbance in the legally protected species including the endemic species. |
