Juvenile coastal fish are drawn to turbid shallow waters and to mangrove structures, where they have better protection from predators. [ 11 ] [ 12 ] As the fish grow, their foraging ability increases and their vulnerability to predators decreases, and they tend to shift from mangroves to mudflats . [ 13 ]
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.

Limited to smaller prey items, juvenile tilapia are dependent upon phytoplankton and small Salton Sea invertebrates. Oreochromis mossambicus is an adaptable species of tilapia. During periods of food scarcity, Oreochromis mossambicus feeds on fish waste and other detritus. [30]
Oreochromis leucostictus is a relatively deep-bodied tilapia with a fairly small mouth, narrow, rounded head and high back. Juvenile are pale, countershaded and have around 8 thin faint dark bars on the flank beneath the dorsal fin, with other bars on the head and tail. The fins are faintly spotted and there is a rather vague dark 'tilapia mark ...
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 2016, juvenile Nile tilapia were given a food containing dried Schizochytrium in place of fish oil. When compared to a control group raised on regular food, they exhibited higher weight gain and better food-to-growth conversion, plus their flesh was higher in healthy omega-3 fatty acids. [14] [15]

The spotted tilapia (Pelmatolapia mariae [2]), also known as the spotted mangrove cichlid or black mangrove cichlid, is a species of fish of the cichlid family. [3] It is native to fresh and brackish water in West and Central Africa , [ 3 ] but has been introduced to other regions where it is considered invasive .
