Mozambique tilapia are resistant to wide varieties of water quality issues and pollution levels. Because of these abilities they have been used as bioassay organisms to generate metal toxicity data for risk assessments of local freshwater species in South Africa rivers.
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.

There are concerns that Mozambique tilapia will invade the rivers of the Murray-Darling Basin. [18] [19] As tilapia can thrive in fresh, brackish and salt water habitats, [20] it is thought that tilapia can quickly infest neighbouring rivers. Tilapia, like eels or bull sharks, can enter new river systems via the sea.
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]
Oreochromis leucostictus (the blue-spotted tilapia) is a species of cichlid native to Albertine Rift Valley lakes and associated rivers in DR Congo and Uganda. It has now been introduced widely elsewhere East Africa , and is believed to have negative ecological impact, particularly on native tilapias .
The Wami tilapia is a tilapiine cichlid that grows to over 20 cm in length and is considered a useful food fish in Tanzania and the island of Zanzibar, which is recognized as a potential origin. It is tolerant of brackish water and grows well in saline pools, making it particularly suitable for aquaculture by communities living close to the sea.
Tilapia production in Brazil increased 3 - 4 percent in 2022. Philippines: 267,735 In the Philippines, several species of tilapia have been introduced into local waterways and are farmed for food. Tilapia fish pens are a common sight in almost all the major rivers and lakes in the country, including Laguna de Bay, Taal Lake, and Lake Buhi.
