영문 초록

This study adopts the marine environment research in 2002 for preservation and management of the ecosystem and fishery resources of the East China Sea. We carried out bottom trawl and acoustic survey from July 4 to 10 in 2002. During the survey, a total of 9 locations were towed along with hydroacoustic transect lines, intervals of which were about 30 ㎚ latitudinal, covering areas of 30˚ 30’ ~ 33˚ .00’ N and 123˚ 45’ ~ 120˚ E. We have been obtained giographical distribution of fisheries resources by the EK-500 echo sounder system. The high density were observed along the north-western part of the East China Sea, the volume backscattering coefficient of which were from -55㏈ to -53㏈. The serival dominant fish of which were common mackerel (Scomber japonicus), Yellowfin horse mackerel (Trachurus japonicus), and Squid.
