A wide range of species are fanned including fish, crustaceans and molluscs, bivalves and aquatic plants (seaweed). In 2011, OECD countries produced about 6.85 million tonnes including aquatic plants of which diadromous fish (e.g. salmon) contributed 36.6% followed by molluscs (27.8%), aquatic plants (19.8%), marine fishes (8.8%), freshwater fishes (4.2%), and crustaceans (2.5%) (Source: Fisheries and Aquaculture Information and Statistics Service, FAO) (Table 3.1). The OECD/FAO Agriculture Outlook 2013 expects world fisheries production to expand to a total of 181 million tonnes by 2022 (which includes 15,6 million tonnes of fish for reduction to meal and oil), of which 85 million tonnes will come from aquaculture. These projections seem to be rather conservative compared to the increases that have taken place over the past two decades.
