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.

Groupers can be fed tilapia whose growth was stunted by overcrowding. For milkfish, marine cages are more intensive and can produce higher output per unit area than in other locations. [11] Growth rates for caged tilapia vary from four months to a year depending on environmental conditions.
In small systems, the fish are often fed commercial fish food, and their waste products can help fertilize the fields. In larger ponds, the pond grows water plants and algae as fish food. Some of the most successful ponds grow introduced strains of plants, as well as introduced strains of fish. [32] Control of water quality is crucial.
The aquaculture of salmonids is the farming and harvesting of salmonid fish under controlled conditions for both commercial and recreational purposes. Salmonids (particularly salmon and rainbow trout), along with carp and tilapia, are the three most important fish groups in aquaculture. [2]
Hatcheries produce larval and juvenile fish, shellfish, and crustaceans, primarily to support the aquaculture industry where they are transferred to on-growing systems, such as fish farms, to reach harvest size. Some species that are commonly raised in hatcheries include Pacific oysters, shrimp, Indian prawns, salmon, tilapia and scallops.
In doing so, tilapia often out compete native fish, create turbidity in rivers by digging, and can reduce available sun light for aquatic plants. Tilapia greatly affect and alter local habitat. Many environmental problems wrought by tilapia have been observed in different locations, including Australia, the Philippines, and the United States ...
In 1998, the first commercial farming of tilapia able to survive in brackish water took place in Negros Occidental, in this case a hybrid of Mozambique tilapia and Oreochromis urolepis hornorum. Tilapia farming began to replace milkfish farming. [4] The fisheries code also included general provision for closed seasons to protect target species.
