To help tilapia raisers save on the cost of commercial feeds and produce healthier stock, Dr Redentor S. Gatus, regional director of the Department of Agriculture Regional Field Unit III, is conducting an experimental organic tilapia culture in his 3,000-square meter, fishpond in Candaba, Pampanga.
Dr. Gatus feeds his stock with the Organic Aqua Feeds (OAF), which is invented by Engr. Walther Alvarez who also invented Atovi, an organic feed additive for chickens and pigs.
Engr. Alvarez said that raising organic tilapia can be done when there is a profuse and sustained growth of algae, bryophytes, phytoplanktons, and zooplanktons in the natural habitat of the fish. Enhanced growth of these natural foods of the fish also results in the production of an ample supply of dissolved oxygen that tilapia needs. Aside from this, if there is a constant and reliable supply of oxygen, it wouldn’t be necessary to have an aerator to stir the fishpond.
To promote the growth of these natural foods, OAF is applied four weeks before the fingerlings are dispersed into the pond. By that time there is already a profuse supply of natural foods in the pond. Feed the fingerlings daily with OAF in addition to the natural foods in the pond, and the month-old tilapia will grow fast, remarkably gain weight, and develop their immune system.
