As a part of resource biological research on fish appearing in the East China Sea. This study investigated the species composition of demersal fish caught with bottom trawl from June 24 to 27, 2001. The fish caught 2 classes 17 orders 49 families 67 species in appeared in sampling period. In these, Percifomes were dominant identified into 21 families, 26 species accounted for 56.72% in the fish fauna and followed by Scorpeniformes (5 families, 12 species). Of the 49 families, dominant identified into Triglidae, Scorpaenidae. Among 67 species dominant identified appeared in the area Trachurus japonicus of the total fishes collected. The diversity index(H’)of each stations in the East China Sea, ranged between 0.2685~2.0714 and the evenness was ranged between 0.0856~0.7660, lowest in station 5 and 7. The dominance index ranged between 0.5185~0.9693 highest in station 7.
