After growing steadily, aquaculture is for the first time set to contribute half of the fish consumed by the human population worldwide. This issue of The State of World Fisheries and Aquaculture features some aspects of fisheries and aquaculture that receive increasing attention. These include climate change, the use of marine genetic resources in areas beyond national jurisdiction, and the proliferation of private standards and certification schemes in the international fish trade. This report also highlights some of FAO's special studies. Among these are the use of wild-fishery resources as seed and feed in aquaculture, and reviews of the world's shrimp fisheries and of the management of marine capture fisheries in the Pacific Ocean.
