영문 초록

This study adopts the marine environment research in 2001 for preservation and management of the ecosystem and fishery resources of the East China Sea. We carried out bottom trawl and acoustic survey from June 23 to 29 in 2001. During the survey, a total of 9 locations were towed along with hydroacoustic transect lines, intervals of which were about 30nm latitudinal, covering areas of 30°30′N-34°.00′N and 126°-128°E. We have been obtained geographical distribution of fisheries resources by the EK-500 echo sounder system. The high density were observed along the south-eastern part of the East China Sea, the area backscattering coefficient of which were from 200 to 1400. The serival dominant fish of which were Yellowfin horse mackerel(Trachurus japonicus), Red seabream(Pagrus major) and Blackmouth goosefish(Lophiomus setigerus). At that time, the temperature and salinity near the bottom were 18~21℃ and 34.0~34.4‰.
