To satisfy this requirement, more than 50 percent of the world fish oil production is fed to farmed salmon. [102] Farmed salmon consume more wild fish than they generate as a final product, although the efficiency of production is improving. To produce one kilograms of farmed salmon, products from several kilograms of wild fish are fed to them ...
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
It covers 11.4 million square kilometres (4.38 million sq mi), which is the second largest zone in the world, exceeding the land area of the United States. [5] According to the FAO, in 2005, the United States harvested 4,888,621 tonnes of fish from wild fisheries, and another 471,958 tonnes from aquaculture. This made the United States the ...

According to a 2019 FAO report, global production of fish, crustaceans, molluscs and other aquatic animals has continued to grow and reached 172.6 million tonnes in 2017, with an increase of 4.1 percent compared with 2016. [23] There is a growing gap between the supply of fish and demand, due in part to world population growth. [24]
Sustainable fish farming practices do not use dangerous chemicals, hormones, or antibiotics on their fish, which benefits the surrounding marine environment, and the human consumers themselves. In addition to this, sustainable fish farming is able to control what their fish eat: farmers will take care to keep the fish's diet healthy and balanced.
World capture fisheries and aquaculture production by species group [1]. The global commercial production for human use of fish and other aquatic organisms occurs in two ways: they are either captured wild by commercial fishing or they are cultivated and harvested using aquacultural and farming techniques.
World capture fisheries and aquaculture production by species group [1] This is a list of aquatic animals that are harvested commercially in the greatest amounts, listed in order of tonnage per year (2012) by the Food and Agriculture Organization. Species listed here have an annual tonnage in excess of 160,000 tonnes.
