The contribution of aquaculture systems to global aquaculture production

This article summarises the development of aquaculture since 2000 and its integration into the global food system. The main topics covered are: aquaculture systems (which are highly diverse); aquaculture production (mainly from inland aquaculture and marine aquaculture); growth of annual production factors (intensification, the use of more and better feeds, improved produc-tion management, and increased attention to biosecurity); land use (aquaculture is more efficient than terrestrial animal production); the challenge of water use; reducing water consumption and facilitating nutrient recovery and reuse; and future development and recommendations.
