International trade in fishery products has increased, together with the absolute and relative importance of aquaculture, as a source of fish production. Shrimp and salmon are two examples of species grown in developing countries that are traded internationally.

Within the framework of its continued efforts to reduce food insecurity and alleviate poverty, the FAO Fisheries and Aquaculture Department encourages commercial or business-oriented aquaculture as a means of increasing food availability and accessibility, employment and income, and improving national economies, especially in developing countries.
