A highly effective, safe, and sustainable way to achieve all-male tilapia is through using super male tilapia which produce close to 100% male offspring without the use of hormones. This has been possible through a more than 35-year natural selection breeding programme involving feminization and progeny testing to supermales that carry the YY sex chromosome that produce at least 96% natural male tilapia (NMT) without fail. However, the YY supermale’s powers last only one generation as all of its offspring carry the regular XY sex chromosome which if used to breed will produce 50% female and 50% male just as in mother nature so there is no adverse effect on the ecosystem.

As NMT fingerlings are not hormone-treated, they have far superior immune systems from the very start resulting in much higher survival rates during the vulnerable hatchery phase as well as during the grow-out phase. Farming mono-sex male tilapia results in a faster Average Daily Growth Rate (ADG), better FCR and higher overall yields combined with lower mortality significantly increasing farmer’s profitability.

• Always works (at least 98%)
• Always natural (XY) male
• Easy to use
• No demolition of immune system
• No harm employees
• No ecological harm (Natural males)

Quite simply, YY super male tilapia is a game changer for tilapia farming for the years to come. PT Indo Aqua Sukses is the only private tilapia hatchery in Indonesia to have YY male tilapia.
