China,Japan and Korea have exploited the fishery resources in the East China Sea area long time before,and the area is the traditional fishing ground for the three countries all the time.As over-fishing for a long time,the commercial stocks of the area have been declined in general,so some actions must be taken urgently to conserve the stocks.However,most of the fish-es in this area travel seasonally along the coastal lines of the three countries,therefore,the stocks shall be conserved successfully none but cooperation among the three countries.More-over,this also complies with the provision of the United Nations Convention on the law of the sea.The three countries have cooperated in the fisheries production and management for a long time,which provide a good foundation for co-management and joint-conservation to the fishery resources in the East China Sea area.Nevertheless,co-management and joint-conservation is still faced with some difficulties at present,so this paper proposes that different schemes should be practised in different phases,that is,the first priority is to control fishing efforts in the near fu-ture and to implement total allowable catch(TAC)system in the long term.
