Abstract: Litter at the bottom of the sea is recently concern as well as the problems of litter pollution of land. We collected litter retained in the catches of bottom otter-trawl and beam-trawl operations that were conducted between 2004 and 2006. Collected litter was classified into natural and synthetic materials and their places of manufacture (country) were identified. Density of litter originated in China was O-31.4 pieces/km^2, litter from Korea, O-1.4 pieces/km^2, and litter from Japan, 0-3.2 pieces/km^2 for 3 years, respectively. We consider these litter were discarded from sLuling ships in the East China Sea. International action should be considered to mitigate this problem.
