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]
The decline in wild fish stocks has increased the demand for farmed fish. [22] However, finding alternative sources of protein and oil for fish feed is necessary so the aquaculture industry can grow sustainably; otherwise, it represents a great risk for the over-exploitation of forage fish. [23]
Fish farming and shellfish production usually spew far less greenhouse gas emissions than production of beef and other animal protein, but aquaculture can still cause serious environmental problems.
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.
Total imports peaked in 2005, when they represented 30% of total consumption. A consistent decline occurred over the next 15 years, as oil production doubled and domestic use receded. This allowed the United States to be a net exporter of energy for the first time in 70 years. As of 2021, the US net exports 3.9% of energy production. [18]
Global energy consumption, measured in exajoules per year: Coal, oil, and natural gas remain the primary global energy sources even as renewables have begun rapidly increasing. [1] Primary energy consumption by source (worldwide) from 1965 to 2020 [2] World energy supply and consumption refers to the global supply of energy resources and its ...
Aquaculture is the most rapidly expanding food industry in the world [7] as a result of declining wild fisheries stocks and profitable business. [2] In 2008, aquaculture provided 45.7% of the fish produced globally for human consumption; increasing at a mean rate of 6.6% a year since 1970.
