Tilapia ( Oreochromis niloticus ) is a freshwater aquaculture commodity with high demand and economic value. With developing breeding technology, hybrid tilapia also grows in popularity. Pandu tilapia is a strain of Singapore tilapia, while Kunti tilapia is a GIFT (Genetically Improved Farmed Tilapia) strain. To ensure the continuity of good fingerling stock, the individual selection needs to be conducted on Pandu and Kunti Tilapia broodstock candidates. The family selection method was chosen using 125 pairs of broodstock candidates. The male and female ratio is 1: 1 with horizontal breeding where a broodstock was mated with another fish from its own family or strain to ascertain that there is no cross-breeding. Larvae hatched from the spawning were reared in a nursery pond, then graded. The top 50% fish was reared until reaching the adult stage and bred again. The broodstock candidates were then tested for its performance and mass spawned.
