Similar to other tilapia, Nile tilapia are maternal mouthbrooders and extensive care is, therefore, provided almost exclusively by the female. After spawning in a nest made by a male, the young fry or eggs are carried in the mouth of the mother for a period of 12 days. Sometimes, the mother pushes the young back into her mouth if she believes ...
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.

Like the Nile tilapia, the kidney of some fish shows its three parts; head, trunk, and tail kidneys. [36] Fish do not have a discrete adrenal gland with distinct cortex and medulla, similar to those found in mammals. The interrenal and chromaffin cells are located within the head kidney. [36]
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ in bony fish (but not cartilaginous fish [1]) that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift via swimming, which expends more energy. [2]
The Nile Tilapia (Oreochromis niloticus) is a species of tilapia, a cichlid fish native to the northern half of Africa and the Levante area (Lowe-McConnell, 1988). [4] Numerous introduced populations exist outside its natural range. The Nile Tilapia reaches up to 60 cm in length, and can exceed 5 kg.
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.
Because of the introduced Nile perch (Lates niloticus), Nile tilapia (Oreochromis niloticus), and water hyacinth, deforestation that led to water siltation, and overfishing, many Lake Victoria cichlid species have become extinct or been drastically reduced. By around 1980, lake fisheries yielded only 1% cichlids, a drastic decline from 80% in ...
