Abstract
The fish species composition and its seasonal variation of the middle East Sea of Korea were investigated from May 2004 to January 2005 using gill and set nets. A total of 59 species of fishes belonging to 31 families in 11 orders were identified in the gill and set nets; 33 species in 15 families and 6 orders were collected by the gill net, and 36 species in 26 families and 10 orders were collected by the set net. Among the fishes collected by gill net, the order Scorpaeniformes was dominant; the number of species as well as individuals was highest in summer; the biomass was highest in winter. However, in fishes collected by set net, the order Perciformes was dominant, the number of species was highest in autumn, the number of individuals was highest in spring, and the biomass was highest in winter. The fish composition of the middle East Sea differed considerably from that of the south East Sea, especially in the species composition of the order Scorpaeniformes and Pleuronectiformes. Principal component analyses for each net showed that the fish species composition depends on the kind of net used, even though the investigation was carried out in the same area and at the same time.
