The theoretical research about the ecosystem-based fishery management

At present,marine fishery resources in our country have been highly exhausted;the degradation of marine ecosystems is increasingly serious and some of ecosystems have lost their functions of ecology indeed.Some reasons lie in that the single species is listed in the target of management,under the traditional fishery management,and that the interactions and effect between the habitat,predator,prey and the ecosystem are ignored.To face this,it is obviously necessary and exigent that we should adjust the cell of management and build the system of ecosystem-based fishery management.The author introduces the concept,objectives and principles of the ecosystem-based fishery management,and puts forward some opinions about how to improve the actual system of fishery management of our country.
