Here we give you some facts about fish.
The FAO (Food and Agriculture Organization) an UN organization states in their State of the World Fisheries and Aquaculture report of 2014 (see p. 61), of the United Nations:
“World per capita apparent fish consumption increased from an average of 9.9 kg in the 1960s to 19.2 kg in 2012 (preliminary estimate)… A portion of 150 g of fish can provide about 50–60 percent of an adult’s daily protein requirements.” (see page 22 of PDF File).
Human Fish Consumption has risen over the years and continues to do so:
2007 – 17.6 kg per capita fish consumption
2010 – 18.5 kg per capita fish consumption
2012 – 19.2 kg per capita fish consumption
It is important to keep in mind that aquaculture production can be categorized into:
1 – inland aquaculture (land-based farming) which generally uses freshwater but some do use saline or saline-alkali water inland, AND
2 – mariculture which describes production operations in the sea and intertidal zones.
Aquaculture accounts for about 50% of the fish that is used for food.
According to the FAO report (see p. 192 in PDF file), aquaculture is the fastest growing food sector.
