  • The Nile tilapia (Oreochromis niloticus) is a species of tilapia, a cichlid fish native to Africa from Egypt south to east and central Africa, and as far west as Gambia.
  • It is also native to Israel, and numerous introduced populations exist outside its natural range (e.g., Brazil).[2] It is also commercially known as mango fish, nilotica, or boulti.
  • The Nile tilapia, a gonochoristic teleost fish with an XX/XY sex-determining system, provides an excellent model for studying gonadal sex differentiation because genetic all-females and all-males are available[1][2].
