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.

Snails that are affected by this parasite are the Cerithideopsilla conica. Fish that come in contact with this parasite are Mugil cephalus, Tilapia milotica, Aphanius fasciatus, and Acanthgobius sp. [2] Humans and mammals will come in contact with this parasite by the consumption of contaminated or raw fish. [3]
Parasites can provide information about host population ecology. In fisheries biology, for example, parasite communities can be used to distinguish distinct populations of the same fish species co-inhabiting a region. [9] Additionally, parasites possess a variety of specialized traits and life-history strategies that enable them to colonize hosts.
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 blue tilapia (Oreochromis aureus) is a species of tilapia, a fish in the family Cichlidae. [2] Native to Northern and Western Africa, and the Middle East, through introductions it is now also established elsewhere, including parts of the United States, where it has been declared an invasive species and has caused significant environmental damage. [3]
Due to the low host specificity of the parasite, Ich infection is known from all freshwater fish systems examined. However, the susceptibility and the impact differ between host species. Rainbow trout , catfish and eels are highly susceptible fish species and uncontrolled infections lead to almost 100% mortality.
The parasite severs the blood vessels in the fish's tongue, causing the tongue to fall off. It then attaches itself to the remaining stub of tongue and the parasite itself effectively serves as the fish's new "tongue". [2] Many species of Cymothoa have been identified, [3] and only cymothoid isopods are known to consume and replace the host's ...
The black tilapia can grow to the recorded maximum length of 35.5 cm (14 inches). [3] The fish is silvery to steel-grey, with white abdomen. There is a red or orange margin on the dorsal and grey or black marblings on the gill-cover. [4]
