Tilapia (/tÉ¨ËlÉËpiÉ/ ti-LAH-pee-É) is the common name for nearly a hundred species of cichlid fish from the tilapiine cichlid tribe.Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers and lakes and less commonly found living in brackish water.ilapia are unable to survive in temperate climates because they require warm water. The pure strain of the blue tilapia, Oreochromis aureus, has the greatest cold tolerance and dies at 45 Â°F (7 Â°C), while all other species of tilapia will die at a range of 52 to 62 Â°F (11 to 17 Â°C).
Commercially grown tilapia are almost exclusively male. Being prolific breeders, female tilapia in the ponds or tanks will result in large populations of small fish. Whole tilapia can be processed into skinless, boneless (PBO) fillets: the yield is from 30% to 37%, depending on fillet size and final trim.hailand has its share of fish farms and fish pens devoted to the culture of tilapia species. In March 2007, millions of caged tilapia in the Chao Praya river died as the result of a massive fish kill. The cause for this was determined to be oxygen deprivation on a massive scale, one of the causes for fish kills.
