Abstract

This study was investigated in order to find composition and density of fisheries resource using bottom trawl in April, July, August, and November 2022 in the East China Sea. The average density of fisheries resource was estimated using the swept area method. As a result, 35 species were collected from the East China Sea. These included 21 fishes, six crustaceans, six cephalopods and two echinoderms. Seasonally, the average density of crustacean individuals per unit area were highest in November (692.1 inds./km2), while cephalopod individuals per unit area were highest in August (39.4 inds./km2). The average density of fish individuals per unit area were highest in August at 355.0 (inds./km2).
