초록

Seasonal variation of species composition in the coastal waters off Wangdol-cho were investigated using the catches by gill net and trammel net from 2002 to 2004. A total of 58 species was collected and classified into 15 orders and 34 families. Of the 58 species identified, Scorpaeniformes and Perciformes accounted for 62.1% of the species. 35 species in 11 orders and 22 families were collected by gill net and 51 species in 15 orders and 30 families were collected by trammel net. The number of species was high in summer and autumn and lowest in winter. Catches were correlated with sea water temperature. The numbers of individuals and their biomass were 5,295 inds. and 1,890 kg, with the highest values achieved in summer and the lowest in spring. The most dominant species were Pleurogrammus azonus and Gadus macrocephalus. The seasonal species community showed a high similarity between summer and autumn.
