Abstract
This study was analysed the species composition of demersal fishes caught by a bottom trawler, KAYA, in the winter season during 4 years and the study area was the eastern fishing ground in depth of about 110m, 40 miles eastward from Jeju Island, Korea. A total of 54 species were collected, including 40 species of Pises, 9 species of Mollusks, 5 species of Crustaces. The number of individuals and biomass of unit area was $7,978ind/km^2$ and $1,800kg/km^2$, respectively. The dominant species in winter season were Dentex tumifrons, Carangoides equula, Callanthias japonicus, Thamnaconus modestus and Pagrus major. And these also were caught every year. The ranges of the diversity index(H') were 1.97 to 2.40, the richness(R) 1.91~4.59, the evenness(E) 0.54~0.83 and the dominance(D) 0.42~0.61.
