The fish fauna of the Buan Dam, Chollabuk-do, Korea which was constructed in 1995 was surveyed in 1994 and 1998. 14 fish species were collected in the Buan Dam and 19 species were recognized in the brackish waters along the lower course of the dam in 1998. It was remarked that the dominant species in the dam has been changed dramatically from Zacco platypus and Z. temmincki to Pseudorasbora parva and Squalidus gracilis majimae within the three years after the dam construction. And also the number of Carassius auratus and Sirulus asotus were gradually increased in the dam. However, lksookimia pumila, the threatened fish species of Korea, was decreased sharply and restricted conspicuously by fragmentation of the habitat. The positive strategies should be considered for the species conservation of lksookimia pumila in the Buan Dam.
