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.

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.
The feeds, in the form of granules or pellets, give nutrition in a stable and concentrated form, enabling the fish to feed efficiently and grow to their full potential. Many of the fish farmed more intensively around the world today are carnivorous, such as Atlantic salmon , trout , sea bass, and turbot .
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.
