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 .
Fish with low inbreeding showed almost twice the aggressive pursuit in defending territory than fish with medium inbreeding, and furthermore had a higher specific growth rate. A significant effect of inbreeding depression on juvenile survival was also found, but only in high-density competitive environments, suggesting that intra-specific ...
Spawning and brood-raising reduce the growth rate of the tilapia, so introduction of Cichla is thought to maintain a high growth rate in the tilapia. They are also raised commercially for the aquarium trade; Asia is one of the main sources for aquacultured peacock bass. As a large predatory fish they are informally referred to as "monster fish".
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.

Some fish, like salmon, spend almost their whole life muaturin in the ocean, then swim many miles up their ancestral rivers, to lay their eggs, commonly dying after spawning. though most commonly associated with fish, spawning triggers also occur in bivalves [1] [2] and corals.
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.
The spawn (eggs) of a clownfish. The black spots are the developing eyes. Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and ...
Skeletal anatomy of Tilapia [3] Consider the tilapia shown in the diagram. Like most fish, the tilapia has a streamlined body shape reducing water resistance to movement and enabling the tilapia to cut easily through water. Its head is inflexible, which helps it maintain forward thrust. [3]
