| Fish fauna of 13 sites in a main channel and its tributaries of the Taehwa River and 9 Sites of other headwater streams in the Ulsan area (Mt. Gaji) were investigated from February 1999 to October 2000. All sites were the 1st to 5th order streams in the Ulsan area, and 10 sites (45.5%) were intermittent streams. A total of 2,695 flsh specimens were collected and classified into 14 families and 44 species. Cyprinidae accounted for 40.9% (18 species) of the total fish species collected and 68.4% (1,845 ind.) of the total abundance. Subdominant families were Cobitidae (6 species; 78 ind.), Gobiidae (5 species; 240 ind.), and Gasterosteidae (2 species: 128 ind.). Zacco temmincki (RA 23.0%, 14 sites) was the dominant species; subdominant species were Moroco oxycephalus (20.2%, 11 sites), Zacco platypus (8.0%, 10 sites), Mugil cephalus (5.2%, 3 sites). Among the total species, 8 species were endemic species to Korea. The dominant Korean endemic species was Squalidus chankaensis tsuchigae (53.6% of Korean endemic species) and subdominant species were Iksookimia longicorpa (20.5%), and S. japonicus coreanus (6.6%) . Due to the intermittent nature of streams in the Ulsan area, a conservation program of nsh fauna is strongly needed. |
