The ichthyofauna and community structure in the Chuncheon Reservoir, Korea, were investigated from August 2003 to April 2004. The total number of fish caught from the period was 10,821 fish representing 41 species and 13 families. There were 16 Korean endemic species, including Hemibarbus mylodon, Acheilognathus yamatsutae and Odontobutis platycephala. Dominant species was Hypomesus olidus $(30.69%) $ and subdominant species was Hemibarbus labeo $(14.70%)$. Also, Zacco platypus $(10.57%)$, Zacco temminckii $(9.66%)$, Micropterus salmoides$(4.81%)$, Rhinogobeus brunneus $(4.28%)$ and Microphysogobio yaluensis $(3.10%)$ were numerous. The biomass of collected fishes were Hemibarbus labeo (34.63 kg), Hypomesus olidus (19.01 kg), Cyprinus carpio (12.77 kg), Opsariichthys uncirostris amurensis (11.28 kg), Zacco platypus (8.04 kg). Among the 7 introduced fishes in Chuncheon Reservoir Carassius cuvieri, Hypophthalmichthys molitrix and Micropterus salmoides were originated from foreign countries, and others (Anguilla japonica, Hypomesus olidus, Oncorhynchus masou mason and Chaenogobius urotaenius) were introduced from other native river systems. |
