Coastal Aquaculture and Mariculture (2+1)

1.1.1. Global aquaculture production - total

• Aquaculture is a relatively recent, fastest growing food production system.
• It has grown at an annual rate of 8.3 percent between 1970 and 2008, while the world population grew at a rate of 1.6 percent during the same year.
• This has resulted in annual per capita supply of food fish from a mere 0.7 kg in 1970 to 7.8 kg in 2008 through aquaculture.
  
• The global production food fish through aquaculture stood at 52.5 million tonnes valued at 98.5 billion US dollars in 2008, accounting for 45.7 percent of the total world fish production by quantity and 51.2 percent by value.
• The total aquaculture production including both plants and animals was 68.3 million tonnes, valued at 106 billion US dollars.
  
• The output from world aquaculture has increased substantially in the last 6 decades, up form a meager 1 million tonne in 1950 to 52.5 million tonnes in 2008 and is predicted to grow further, although the rate of increase may slow down.
  
• Since the fish production from capture fisheries has stagnated around 90 million tonnes since the mid 1980s, aquaculture is expected to supply the ever increasing demand for fish.
