Fish fauna of fishes collected from the Saemankum area in the west coast of Chollabuk-do was studied from October 1996 to April 1999. The specimens collected from the five sites in this area were identified into 107 species belonging to 83 genera and 52 families. Of them the largest group of fishes was order Perciformes, comprising 50 species and 21 families, and showed 46.7% in total numbers of species. Next larger groups were orders Scorpaeniformes and Pleuronectiformes containing 16 and 14 species respectively. In this area, the group comprising a lots of species was the family Gobiidae taking 13 species, and next groups were the families of Sciaenidae (6 species), Engraulidae (5 species) and Pleulonectidae (5 species). The dominant species was Engraulis japonicus which is 23.4 ％ in total indiyidual numbers, and subdominant species was Thryssa kummazensis which is 18.5%. The important species economically in the Saemankum area were Anguilla japonica, E. japonicus, T. kummalensis, Konosirus punctatus, Sardinella zunasi, Mugil cephalus, Argyrosomus argentatus, Pseudosciaena polyactis, Collichthys lucidus, Paralichthys olivuceus and Cynoglossus joyneri. The species of high frequency in this area from February to June every year were Anguilla japonica, E. japonicus, T. kammalensis, K. punctatus, S. zunasi, Coilia nasus, Syngnatuus schlegeli, P. polyactis, C. lucidus and Pholis fangi. Ophichthus rotundus, Repomucenus leucopoecitus and R. koreanus were Korean endemic species in the west coast of Chollabuk-do. On the other hand, Boleophthalmus pectinirostris was not found during this study, and Periophthalmus modertus, Tridentiger barbatus and Lophogobius ocellioauda sharply decreased in individual numbers in comparison to several years ago.
