|
To investigate the ichthyofauna and habitat type of the fish in Tamjin River system, Korea, fishes were collected with cast net (, ) and dip net () at eight stations seasonally during five years from 2000 to 2004. 56 species belonging to 18 families were collected and 15 Korean endemic species( 26.8%) were investigated. While Coreoperca kawamebari was occurred at every station, the number of individuals and composition were decreased. Anguilla marmorata was not collected and the exotic species didn¡¯t appeared. Dominant species were Zacco platypus(34.2%), Squalidus gracilis majimae (9.4%), Microphysogobio yaluensis(8.1%), Zacco temmincki(6.8%) and Acheilognathus lanceolatus(5.1%). The surveyed stations were clustered into 3 groups: up stream, main stream and estuary. With the cluster analysis using the relative abundance of major fishes at each habitat, fishes were separated into 5 habitat types: U (upstream type), UM (up and main stream type), M (main stream), ME (main stream and estuarine type), and E (estuarine type).
