(The black lines represent the world fishery in metric tons and the blue bar indicate the aquatic production in percentage of the fishery) It is widely acknowledged that fish supplies from traditional marine and inland capture fisheries are unlikely to increase substantially and that the projected shortfalls in fish supply will probably be met mainly from expansion within the aquaculture sector. The potential of aquaculture to meet the challenges of food security and to generate employment and foreign exchange has been clearly demonstrated by the rapid espansion of this sector, which has grown at a rate of almost 10 since 1984 compared with 3 for livestock meat and 1.6 for capture fisheries production.

The contribution
of aquaculture to total aquatic production
|
|
In recent years, the supply of fish has continued to increase steadily and in 1995, total world production of finfish, crustaceans and molluscs from capture fisheries and aquaculture reached 112.9 millions mT ( metrical tonnes). The inclusion of plants in aquatic production raises the total production in 1995 by a further 7.8 millions mT to 120.7 million mT, an increase of around 15.6 million mT since 1989. Much of the increase in annual global aquatic production is attributable to aquaculture. The actual share of aquaculture depends on whether aquatic plants are included or not. For cultured finfish and shellfish, the annual contribution to total finfish and shellfish production rose linearly from 11.7% in 1989 to 18.5% in 1995. When aquatic plants from culture and wild harvest are included the corresponding annual contribution of aquaculture to total aquatic production increased from 14.4% to 23.0% in 1995. For food fish, over a quarter of total world supply was derived from aquaculture! |
