The geographic range for tilapia culture is limited by their temperature-sensitivity. For optimal growth, the ideal water temperature range is 82 to 86 °F (28 to 30 °C), and growth is reduced greatly below 68 °F (20 °C).
The Nile tilapia (Oreochromis ... The species has been recorded at water temperatures between 8 and 42 °C (46 and 108 °F), although typically above 13.5 °C ...
Other than their temperature sensitivity, tilapia exist in or can adapt to a very wide range of conditions. An extreme example is the Salton Sea, where tilapia introduced when the water was merely brackish now live in salt concentrations so high that other marine fish cannot survive. [13]
The redbelly tilapia also can live in a wide range of water temperatures, but in the northern part of its range it sometimes falls below its requirements (minimum 6.5–13 °C [43.7–55.4 °F], depending on a range of factors), resulting in large numbers dying. [10]
The water temperature in its range vary quite significantly with season, at least from 14 to 28.5 °C (57–83.5 °F), [6] but aquarium studies have shown that A. flaviijosephi are almost completely inactive at the lowermost range. [8] A. flaviijosephi is threatened by habitat loss caused by drought
This species constitutes about 4% of the total tilapia aquaculture production worldwide, but is more commonly hybridized with other tilapia species. [33] Tilapia are very susceptible to diseases such as whirling disease and ich. [26] Mozambique tilapia are resistant to wide varieties of water quality issues and pollution levels.
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 .
This has been observed in cases where a fish native to a more tropical region has been introduced to cooler waters, such as the introduction of the tilapia to bodies of water in Florida. Native to Africa's Nile River, the tilapia stop feeding when water temperatures drop below 60 °F (16 °C) and die when it reaches 45 °F (7 °C). Thus ...
