Aquaculture, also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants. Aquaculture involves cultivating freshwater, brackish water and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems. Mariculture, commonly known as marine farming, is aquaculture in seawater habitats and lagoons, as opposed to freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food.
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life or, more commonly, the site where such enterprise takes place. Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies and the oceans. About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem, causing declines in some populations.
The Chinook salmon is the largest and most valuable species of Pacific salmon. Its common name is derived from the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, Tsumen, spring salmon, chrome hog, Blackmouth, and Tyee salmon. The scientific species name is based on the Russian common name chavycha (чавыча).
Lake Volta, the largest artificial reservoir in the world based on surface area, is contained behind the Akosombo Dam which generates a substantial amount of Ghana's electricity. It is completely within the country of Ghana and has a surface area of 8,502 square kilometres. It extends from Akosombo in the south to the northern part of the country.
Tassal is a Tasmanian-based Australian salmon farming company founded in 1986. It was listed on the Australian Securities Exchange (ASX) from 2003 until 2022. Tassal is the largest producer of Tasmanian grown Atlantic salmon, supplying salmon to both domestic and international markets. In November 2022, it was purchased by Cooke Seafood of Canada and delisted from the ASX.
Tilapia has become the third most important fish in aquaculture after carp and salmon; worldwide production exceeded 1.5 million metric tons in 2002 and increases annually. Because of their high protein content, large size, rapid growth, and palatability, a number of coptodonine and oreochromine cichlids—specifically, various species of Coptodon, Oreochromis, and Sarotherodon—are the focus of major aquaculture efforts.
Fishing in India is a major sector within the economy of India contributing 1.07% of its total GDP. The fishing sector in India supports the livelihood of over 28 million people in the country, especially within the marginalized and vulnerable communities. India is the third largest fish producing country in the world accounting for 7.96% of the global production and second largest producer of fish through aquaculture, after China. The total fish production during the FY 2020-21 is estimated at 14.73 million metric tonnes. According to the National Fisheries Development Board the Fisheries Industry generates an export earnings of Rs 334.41 billion. Centrally sponsored schemes will increase exports by Rs 1 lakh crore in FY25. 65,000 fishermen have been trained under these schemes from 2017 to 2020. Freshwater fishing consists of 55% of total fish production.
Fishing in Ghana is made up of both ocean caught fish, as well as freshwater fishing in lakes and rivers.

Aquaculture started to take off in New Zealand in the 1980s. It is dominated by mussels, oysters and salmon. In 2007, aquaculture generated about NZ$360 million in sales on an area of 7,700 hectares. $240 million was earned in exports.
Aquaculture in Australia is the country's fastest-growing primary industry, accounting for 34% of the total gross value of production of seafood. 10 species of fish are farmed in Australia, and production is dominated by southern bluefin tuna, Atlantic salmon and barramundi. Mud crabs have also been cultivated in Australia for many years, sometimes leading to over-exploitation. Traditionally, this aquaculture was limited to table oysters and pearls, but since the early 1970s, there has been significant research and commercial development of other forms of aquaculture, including finfish, crustaceans, and molluscs.
The aquaculture of salmonids is the farming and harvesting of salmonid fish under controlled conditions for both commercial and recreational purposes. Salmonids, along with carp and tilapia, are the three most important fish groups in aquaculture. The most commonly commercially farmed salmonid is the Atlantic salmon.
Organic aquaculture is a holistic method for farming fish and other marine species in line with organic principles. The ideals of this practice established sustainable marine environments with consideration for naturally occurring ecosystems, use of pesticides, and the treatment of aquatic life. Managing aquaculture organically has become more popular since consumers are concerned about the harmful impacts of aquaculture on themselves and the environment.
Ghana'sMinistry of Food and Agriculture (MOFA) is the government agency responsible for the development and growth of agriculture in the country. The jurisdiction does not cover the cocoa, coffee, or forestry sectors. The primary organisation and main area of the presidential administration of Ghana is the nation's Ministry of Food and Agriculture (MOFA), which is in charge of creating and carrying out policies and plans for the agricultural sector within the framework of an efficient national socio-economic development and prosperity agenda. The Ministry's plans and programmes are created, coordinated, and put into effect using frameworks for policy and strategy using a sector-wide approach. The Food and Agriculture Sector Development Policy II and the Medium Term Agriculture Sector Investment Plan were both developed with the aid of MOFA in relation to this.
Offshore aquaculture, also known as open water aquaculture or open ocean aquaculture, is an emerging approach to mariculture where fish farms are positioned in deeper and less sheltered waters some distance away from the coast, where the cultivated fish stocks are exposed to more naturalistic living conditions with stronger ocean currents and more diverse nutrient flow. Existing "offshore" developments fall mainly into the category of exposed areas rather than fully offshore. As maritime classification society DNV GL has stated, development and knowledge-building are needed in several fields for the available deeper water opportunities to be realized.
Geoduck aquaculture or geoduck farming is the practice of cultivating geoducks for human consumption. The geoduck is a large edible saltwater clam, a marine bivalve mollusk, that is native to the Pacific Northwest.
Aquaculture in Madagascar started to take off in the 1980s. The industry includes the cultivation of sea cucumbers, seaweed, fish and shrimp and is being used to stimulate the country's economy, increase the wages of fishermen and women, and improve the regions ocean water quality. Coastal regions of Madagascar are reliant on the Indian Ocean's marine resources as a source of food, income, and cultural identity.
Blue economy is a term in economics relating to the exploitation, preservation and regeneration of the marine environment. Its scope of interpretation varies among organizations. However, the term is generally used in the scope of international development when describing a sustainable development approach to coastal resources. This can include a wide range of economic sectors, from the more conventional fisheries, aquaculture, maritime transport, coastal, marine and maritime tourism, or other traditional uses, to more emergent activities such as coastal renewable energy, marine ecosystem services, seabed mining, and bioprospecting.
Aquaculture in the United Kingdom is dominated by salmon farming, then by mussel production with trout being the third most important enterprise. Aquaculture in the United Kingdom represents a significant business for the UK, producing over 200,000 tonnes of fish whilst earning over £700 million in 2012 (€793 million).
Aquaculture has a long history in Taiwan and is an important component of the Maritime industries of Taiwan.
