[3]
The pure strain of the blue tilapia, Oreochromis aureus, has the greatest cold tolerance and dies at 7 °C (45 °F), while all other species of tilapia die at a range of 11 to 17 °C (52 to 62 °F).
For example, blue tilapia (Oreochromis aureus) (itself commonly confused with another species often used in aquaculture, the Nile tilapia, O. niloticus), Mozambique tilapia (O. mossambicus), blackchin tilapia (Sarotherodon melanotheron), spotted tilapia (Pelmatolapia mariae), and redbelly tilapia (Coptodon zillii) have all become established in ...
