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.

In California, for example, 15 fish farms produce tilapia, bass, and catfish with warm water from underground. This warmer water enables fish to grow all year round and mature more quickly. Collectively these California farms produce 4.5 million kilograms of fish each year. [161]

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.
Consequently, a large component of the fish feed will not be taken up. [26] Crustacean diets are favored possibly as a result of their high protein relative to lipid levels. [24] Whether octopus farming is profitable depends in large part on how much it costs to maintain a steady supply of crustaceans. [25]
Raising fish in cages in a lake in a relatively undeveloped environment. Urban aquaculture employs water-based systems, the most common, which mostly use cages and pens; land-based systems, which make use of ponds, tanks and raceways; recirculating systems are usually high control enclosed systems, [clarification needed] whereas irrigation is used for livestock fish.
