Milkfish – fishkill has been the major cause of bankruptcy to many fish farmers. Yearly, milkfish mortality reaches thousands in Pangasinan and Batangas due to insufficient dissolved oxygen due to high concentration of hydrogen sulfide in the water. This has been solved now by Philippine Atovi Technology. With the available technology, fish kill is avoided because of fast hydrogen sulfide neutralization and strong resistance of fish against temperature extremes (hot & cold). The technology also flushes heavy metals like mercury on the cellular level of fish, and can provide life support in long distance transportation.
