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 ...
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.
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]
With capture fishery production relatively static since the late 1980s, aquaculture has been responsible for the continuing growth in the supply of fish for human consumption. [24] Global aquaculture production (including aquatic plants) in 2016 was 110.2 million tonnes, with the first-sale value estimated at US$244 billion.
No one factor operates in isolation and components of the ecosystem respond differently to each individual factor." [40] In contrast to the traditional approach of focusing on a single species, the ecosystem-based approach is organized in terms of ecosystem services. Ecosystem-based fishery concepts have been implemented in some regions. [41]
Conversely, one of the most unsustainable practices within the fish farming industry occurs is when farmers feed the fish pellets of animal waste. The quality of ocean water in and around fish farms is up to the farmers to maintain, and due to the fact that the mesh cages take up only a certain amount of space in the ocean, fish farmers can ...
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.
The Blue Revolution is the increase in fish and aquatic food production through the sustainable use of water resources, including marine, brackish, and freshwater systems. It encompasses activities like aquaculture (fish farming), the development of fisheries, and the sustainable management of aquatic ecosystems to provide food security ...
