Fishkill has been the major cause of bankruptcy of 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 Atovi Nanotechnology. 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 out heavy metals like mercury on the cellular level of the fish, and can provide life support in long distance transportation.

Dosage & Application

For Feeds

Mix 1 tablespoon of Atovi powder (10 grams) into 4 liters of water. Use a cotton cloth to filter. The filtrates may be safely fed to them. After straining the mixture, transfer it to a hand sprayer and apply to commercial feeds or any other form of meal before feeding. Do this regularly before feeding time to boost their immune system and help them grow fast.

For water in fish pond

For every hectare of fishpond, apply 1 kg of Atovi powder.


Mix 1 kg of Atovi into a drum of water (160-200 liters), then apply to the whole fishpond. Apply Atovi weekly at least for the first two months of culture to be ensured of good quality of water, maintenance of “dissolved oxygen”, and water free from pollution, toxins, chemicals, bacteria, hydrogen sulfide, and other problems.


Atovi helps in the proliferation of algae in the fishpond, which serves as natural food for them. It is best to start applying Atovi during pond preparation before stocking.

*Note: Sea water cannot be applied with Atovi. The feeds or meal given to them can be applied with the technology.
