The “YY super tilapia male technology is considered an effective breeding protocol towards the production of all-male progeny for farming which has a special importance in tilapia farming.

The YY technology is a form of a breeding program which combines feminization and progeny testing resulting what is known by “super tilapia male” with two male sex chromosomes “YY” instead of the usual XY male. These YY males when mating with regular females, the progeny are only males.

In the Philippines, the dissemination of YY technology is being done through accredited hatcheries. There have been funded projects in Philippines on the production and dissemination of YY super tilapia male technology whereas the Bureau of Fisheries and Aquatic Resources (BFAR), and some Pilipino universities collaborated in these projects.
