Overview of production and trade- the role of aquaculture fish supply
Capture fisheries and aquaculture supplied the world with about 108 million tonnes of foodfish in 2005, with aquaculture accounting for 45 percent of the total. Apparent percapita supply reached 16.7 kg (live weight equivalent), the highest on record. Growth in supply from aquaculture more than offset the effects of stable capture fishery production levels and a growing population. Aquaculture continues to grow more rapidly than all other animal food-producing sectors. Worldwide, the sector has grown at an average rate of 8.8 percent per year since 1970, compared with only 1.2 percent for capture fisheries and 2.8 percent for terrestrial farmed meat production systems over the same period. In terms of foodfish supply (excluding 13.4 million tonnes of aquatic plants) the worlds aquaculture sector produced about 15 million tonnes of farmed aquatic products in 2004 (excluding China). Corresponding figures reported for China are about 31 million tonnes from aquaculture and 6 million tonnes from capture fisheries, a powerful indication of the dominance of aquaculture in China. The growth in production of the different major species groups continues, although the increases seen so far this decade are less than those realized during the extraordinary growth in the 1980s and 1990s. Over 240 different farmed aquatic animal and plant species were reported in 2004.
