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 ...
Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
As with other countries, the 200 nautical miles (370 km) exclusive economic zone (EEZ) off the coast of the United States gives its fishing industry special fishing rights. [6] 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]
The surface salinity of the ocean is a key variable in the climate system when studying the global water cycle, ocean–atmosphere exchanges and ocean circulation, all vital components transporting heat, momentum, carbon and nutrients around the world. [84] Cold water is more dense than warm water and salty water is more dense than freshwater.
The U.S. government will invest $240 million in salmon and steelhead hatcheries in the Pacific Northwest to boost declining fish populations and support the treaty-protected fishing rights of ...
In the United States, human rights consists of a series of rights which are legally protected by the Constitution of the United States (particularly by the Bill of Rights), [1] [2] state constitutions, treaty and customary international law, legislation enacted by Congress and state legislatures, and state referendums and citizen's initiatives.
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.
Water resource policy varies by region and is dependent on water availability or scarcity, the condition of aquatic systems, and regional needs for water. [18] Since water basins do not align with national borders, water resource policy is also determined by international agreements, also known as hydropolitics. [19]
