Aquaculture, also known as aquatic farming, is the practice of farming aquatic organisms such as fish, mollusks, crustaceans, and aquatic plants in water environments. This type of farming is becoming increasingly popular due to its potential to supplement the declining wild fisheries, reduce water pollution, and provide food security.

Aquaculture is distinct from fishing, which is the practice of capturing wild fish. The main difference between aquaculture and fishing is that aquaculture is a controlled and purposeful production of aquatic organisms while fishing relies on the exploitation of wild populations. Aquacultured organisms are raised in captivity, either in open-air pens in the coastal ocean or in tanks on land.

Aquacultured species may be used for human consumption, or for stock enhancement for recreational fishing. They may also be used for restocking or relocating fish populations, bioremediation, spawning, freight farming, and research. Aquaculture is widely practiced by countries around the world, with the United States, China, India, and Vietnam leading in production.

Aquaculture can take on various forms, such as recirculating aquaculture systems (RAS) or intensive polyculture systems. RAS consists of tanks or raceways that are stocked with larval or juvenile fish and enclosed with a water re-circulating system. Intensive polyculture systems involve the simultaneous cultivation of multiple species of fish, crustacea, and aquatic plants in tanks or ponds. The goal is to achieve a balance among the different species, where each species benefits from the other species.

Aquaculture is a rapidly growing segment of the agricultural sector and is an important part of global food production. With the world’s population increasing at a rapid rate, aquaculture has the potential to help meet the ever-growing demand for seafood and other aquatic products.
