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).
Warm water species such as Tilapia and Barramundi prefer 24 °C water or warmer, where as cold water species such as trout and salmon prefer water temperature below 16 °C. Temperature also plays an important role in dissolved oxygen (DO) concentrations, with higher water temperatures having lower values for DO saturation.
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]
[1] [2] It also occurs in brackish water, but is unable to survive long-term in full salt water. [2] The species has been recorded at water temperatures between 8 and 42 °C (46 and 108 °F), although typically above 13.5 °C (56.5 °F), [ 2 ] and the upper lethal limit usually is at 39–40 °C (102–104 °F).

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 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 .
Just as 68 degrees F is considered the best temperature for a house in winter, experts call 78 degrees F the magic number for the summer months. This interior temperature should be amenable to ...
