English name: Tilapia
Scientific name: Oreochromis niloticus
Oreochromis niloticus is a species of tilapia, a cichlid fish native to the northern half of Africa and Israel.Numerous introduced populations exist outside its natural range. It is also commercially known as mango fish, nilotica, or boulti.
Oreochromis niloticus reaches up to 60 cm (24 in) in length, and can exceed 5 kg (11 lb). As typical of tilapia, males reach a larger size and grow faster than females.
tilapia can be found in most types of freshwater habitats, such as rivers, streams, canals, lakes and ponds, and ranging from sea level to an altitude of 1,830 m (6,000 ft). It also occurs in brackish water, but is unable to survive long-term in full salt water. The species has been recorded at water temperatures between 8 and 42 °C (46–108 °F), although typically above 13.5 °C (56.5 °F),and the upper lethal limit usually is at 39–40 °C (102–104 °F). There are also some variations depending on the population. For example, those in the northern part of its range survive down to the coldest temperatures, while isolated populations in warm lakes and springs, such as Lake Tana and hot springs in the Awash basin, generally live in waters that are at least 32–33 °C (90–91 °F).
