Tilapia species is a very profitable fish used in inland bodies of water and this fish is so hardy and easily thrives in any bodies of water. Aquaculture is not a success without tilapia because this is the easiest fish to breed and culture however present techniques employed in breeding this fish is still conventional thus the Inventor, M.J Canto-Saan, developed a system where high-breed tilapia is properly raised for 5 months in b-net hapa in earthen ponds. The breeders are then selected, and classified, sex according to gender and transferred to holding b-nets for conditioning of at least 30 days. The breeders are separated in two b-net hapas according to gender.
The selected breeders are fed twice a day with 32 percent crude protein commercial pellets for 30 days. Rows of hapa nets, 6 meters (length) and 3 meters(width)
are installed in earthen ponds (20 meters in length and 40 meters in width) and greening of water is attained by fertilizing the pond with a chicken dung and synthetic fertilzer, 20-20-20. Breeders are put into these hapas at 30 females and 15 males ratio (30:15). Daily monitoring of pH, Dissolve Oxygen, Ammonia content is followed. Each hapa net with paired breeders are fed with commercial feed or rice bran twice a day for twelve (12) days. Fish technicians are task to monitor the hapa nets for surfacing newly-hatched fry. On the 12th day, the hapa nets are "crowd" with crowding bars made of wooden stick or pvc pipes to collect fry, newly-hatched fry and fertilized eggs from each hapa net. Fry and newly-hatched fry are transferred to a nursery net for further rearing. Fry are to be fed with a commercial fry booster made of ground fishmeal
The Fish Hatchery Group is based in General Santos. Fish Hatchery Group developed the J1 aquasystems, a hatchery system where there is no use of flowing water in the incubation of fish eggs. Fish Hatchery Group offers hands on training on establishing hatchery for tilapia, catfish, pangasius.
