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.
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.
Consistent supply of fish from aquaculture facilities is an important market requirement. [7] Broodstock conditioning can extend the natural spawning season and thus the supply of juveniles to farms. [7] [8] Supply can be further guaranteed by sourcing from hatcheries in the opposite hemisphere i.e. with opposite seasons. [9] 2. Genetic improvement
This might be caused by the initial investment needed when starting the system. [10] [11] The use of rice-fish systems has resulted in an increase in rice yields and productivity from 6.7–7.5 tonnes per hectare (3.0–3.3 short ton/acre) and simultaneously also from 0.75–2.25 tonnes per hectare (0.3–1.0 short ton/acre) of fish.

Mariculture, sometimes called marine farming or marine aquaculture, [1] is a branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in seawater. Subsets of it include ( offshore mariculture ), fish farms built on littoral waters ( inshore mariculture ), or in artificial tanks , ponds or raceways ...
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.
Sustainable fish farming practices do not use dangerous chemicals, hormones, or antibiotics on their fish, which benefits the surrounding marine environment, and the human consumers themselves. In addition to this, sustainable fish farming is able to control what their fish eat: farmers will take care to keep the fish's diet healthy and balanced.
