The development of marine fishery is of great significance. This paper analyzed the current situation and existing problems of marine fishery in China and came up with some pertinent recommendations and measures. The area of marine fishery with authentic right is increasing year by year,and pelagic fishery constantly grows and the industrial structure is becoming more and more reasonable. However,there are still problems such as serious pollution of marine environment,frequent occurrence of marine disasters,shrinking space of fishery development,which seriously affect healthy development of the marine fishery. In this situation,it came up with recommendations including strengthening monitoring of marine fishery resources and protection of marine environment,optimizing the industrial structure,and raising the scientific and technological level of marine fisheries,to protect the sustainable development of marine fishery. It is expected to provide references for the development of marine fishery in China.展开更多
