Tilapia

Tilapia

The Tilapias belong to the family Cichlidae. Three genera are well-known namely Oreochromis, Tilapia and Sarotherodon, of which Nile Tilapia belongs to genus Oreochromis. This species is naturally distributed in Palestine, the Nile River as well as most part of African river and lakes. It was introduced in the Philippines in 1972. Its rising popularity is due to their hardiness, resistance to disease, ease to breeding, reasonable growth rate, good taste, and tolerance to a wide range of environmental conditions including temperature and salinity.

Most Tilapias species of the tribe Tilapinii now being used in aquaculture were grouped initially into one genus, Tilapia. The species within this genus were later classified according to differences in their mode of reproduction (Low McConnel, 1959; Trewavas, 1973, 1978, 1982). Species which evolved as substrate spawner but guard their eggs were retained in the genus tilapia while those which orally rear their clutches were grouped into a new species Sarotherodon. Classification of the three genera Tilapia, Sarotherodon and Oreochromis was based largely on the differences on their reproduction, feeding habits and biogeography.
