A raceway farm for freshwater fin fish usually has a dozen or more parallel raceway strips build alongside each other, with each strip consisting of 15 to 20 or more serial sections. [16] The risk of unhygienic conditions increases towards the lower level sections, and can be kept in check by ensuring there are not too many sections and 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.
Aquacultural engineering is a multidisciplinary field of engineering and that aims to solve technical problems associated with farming aquatic vertebrates, invertebrates, and algae. [1] Common aquaculture systems requiring optimization and engineering include sea cages, ponds , and recirculating systems. [ 2 ]
Aquaculture (less commonly spelled aquiculture [1]), 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 (e.g. lotus).
It cultures marine fish, microalgae, bivalves and Artemia. Effluents from seabream and seabass collect in sedimentation ponds, where dense populations of microalgae—mostly diatoms—develop. Clams, oysters and sometimes Artemia filter the microalgae from the water, producing a clear effluent. The farm sells the fish, bivalves and Artemia.
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.
Aquaculture is the farming of fish and other aquatic life in enclosures, such as ponds, lakes and tanks, or cages in rivers and coastal waters. China's 2005 reported harvest was 32.4 million tonnes , more than 10 times that of the second-ranked nation, India , which reported 2.8 million tonnes.
Aquaculture, in the United States, includes the farming of hatchery fish and shellfish which are grown to market size in ponds, tanks, cages, or raceways, and released into the wild. Aquaculture is also used to support commercial and recreational marine fisheries by enhancing or rebuilding wild stock populations.
