Channel catfish quickly became the major catfish grown, as it was hardy and easily spawned in earthen ponds. By the late 1960s, the industry moved into the Mississippi Delta as farmers struggled with sagging profits in cotton , rice and soybeans , especially on those farm areas where soils had a very high clay content.
As an example, tilapia farming is a core component of the economy of Lake Sebu, South Cotabato, in 1994 making up over 50% of total income and employing 10% of workers. [14] Riverine and marine aquaculture provide an economic opportunity for poorer individuals, as access to water is much more available than access to land, which is often the ...
Worldwide, the most important fish species produced in fish farming are carp, catfish, salmon and tilapia. [1] Global demand is increasing for dietary fish protein, which has resulted in widespread overfishing in wild fisheries, resulting in significant decrease in fish stocks and even complete depletion in some regions.
For example, trout and juvenile salmon are less tolerant of degraded water quality and require a more rapid water turnover than catfish or tilapia. [18] The flow rate necessary to maintain water quality can also change through the year, as the temperature changes and the cultured species grow larger.
Tilapia were introduced to Indonesia in 1969 from Taiwan. Later, several species also introduced from Thailand (Nila Chitralada), Philippines (Nila GIFT) and Japan (Nila JICA). Tilapia has become popular with local fish farmers because they are easy to farm and grow fast. Major tilapia production areas are in West Java and North Sumatra.
Tilapia (/ t ɪ ˈ l ɑː p i ə / tih-LAH-pee-ə) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini.

Worldwide, the most important fish species used in fish farming are, in order, carp, salmon, tilapia, and catfish. [28] In the Mediterranean, young bluefin tuna are netted at sea and towed slowly towards the shore. They are then interned in offshore pens (sometimes made from floating HDPE pipe) [39] where they are further grown for the market. [40]
The adaptable tilapia is a commonly farmed fish in South Africa. South Africa has an emerging aquaculture.It consists mainly of culture of freshwater species such as crocodiles, trout, catfish, tilapia, and ornamental fish as well as marine species such as abalone, prawns, oysters, and mussels.
