Many cultured fishes (tilapia, carp, catfish, many others) can be raised on a strictly herbivorous diet. Top-level carnivores (most salmonidae species in particular) on the other hand, depend on fish feed, of which a large portion is usually derived from wild-caught fish ( anchovies , menhaden , etc.).
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.

Fully weaned fingerlings weighing up to one gram are transferred to juvenile culture tanks. [5] [7] Later cobia juveniles can be raised in ponds or shallow, near-shore submerged cages. Juveniles thrive on a wide range of protein and lipid, but there are optimal levels where they get the most benefit.
Mozambique tilapia, like other fish such as Nile tilapia and trout, are opportunistic omnivores and will feed on algae, plant matter, organic particles, small invertebrates and other fish. [19] Feeding patterns vary depending on which food source is the most abundant and the most accessible at the time.
Some species that are commonly raised in hatcheries include Pacific oysters, shrimp, Indian prawns, salmon, tilapia and scallops. The value of global aquaculture farming is estimated to be US$98.4 billion in 2008 with China significantly dominating the market; [ citation needed ] however, the value of aquaculture hatchery and nursery production ...
Since the late-1980s however, populations of feral tilapia have declined. Recently introduced cichlid hybrids (red tilapia O. mossambicus x O. niloticus, possibly also O. honorum and O. aureus) have crossbred with populations of Oreochromis mossambicus, possibly contributing to the decline. Inter-species hybrids tend to produce fewer fry per ...
The redbelly tilapia (Coptodon zillii, syn. Tilapia zillii), also known as the Zille's redbreast tilapia or St. Peter's fish (a name also used for other tilapia in Israel), is a species of fish in the cichlid family. This fish is found widely in fresh and brackish waters in the northern half of Africa and the Middle East.
Depending on the exact species, the maximum length of Coptodon ranges from 5 to 45 cm (2–18 in); the smallest is C. snyderae, which also is the smallest tilapia. [3] Although the individual species typically have different nonbreeding and breeding colors, the sexes are alike.
