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.
Philippine aquaculture is hampered by the lack of a "trash fish" — a cheap fish that can be used to feed farmed fish — as most fish in the Philippines are directly valuable for human consumption. This increases the cost of farming carnivorous fish. Another common impediment is access to juveniles, for fish, crabs, and shrimp.
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 ]
The laboratory was expanded in the 1970s and 1980s to investigate serious disease risks threatening the expanding fish farming industry. During the 1980s research shifted towards determining drug residues in fish for human consumption and environmental problems associated with release of medicines from fish farms.
The buoys/lines are placed next to the fishnets or cages in which the fish grows. [6] In some tropical Asian countries some traditional forms of aquaculture of finfish in floating cages, nearby fish and shrimp ponds, and oyster farming integrated with some capture fisheries in estuaries can be considered a form of IMTA.

The farming of fish is the most common form of aquaculture. It involves raising fish commercially in tanks, fish ponds, or ocean enclosures, usually for food. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery.
Organic aquaculture is a holistic method for farming fish and other marine species in line with organic principles. [1] The ideals of this practice established sustainable marine environments with consideration for naturally occurring ecosystems, use of pesticides, and the treatment of aquatic life. [2]
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 ...
