FisTx Aquaculture Nanotechnology: Nano-Silver and Nano-Disinfectant to Combat Vibrio and Shrimp Diseases
Aquaculture Nanotechnology: What It Is and How FisTx Uses It
Aquaculture nanotechnology applies particles measuring 1–100 nanometers to eliminate bacteria, Vibrio, and viruses that cause disease in shrimp and fish. FisTx is the first aquaculture technology company in Indonesia to produce and apply this technology, through two products: Nano Silver and Nano Disinfektan (nano copper). Both are designed for two application routes at once — mixed into feed or spread directly into pond water — giving farmers biosecurity control from both inside and outside the shrimp's body.
What Is Aquaculture Nanotechnology?
Aquaculture nanotechnology works with materials at the 1–100 nanometer scale — roughly 1/40,000th the diameter of a human hair — allowing active particles to penetrate directly through a pathogen's cell wall, rather than just coating its surface the way conventional disinfectants do. This scale is what makes nano silver and nano copper far more efficient at killing bacteria than chlorine-based disinfectants like kaporit, even at much lower doses.
FisTx developed this technology through internal research, validated using a Transmission Electron Microscope (TEM) at the Chemistry Laboratory, Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Gadjah Mada (UGM), confirming a consistent particle size of 4–7 nanometers with even distribution and no clumping.
Nano Silver vs. Nano Disinfektan: What's the Difference?
Although both are nanoparticle-based, these two FisTx products play different roles in a farming system:
| Aspect | Nano Silver (AgNPs) | Nano Disinfektan (CuNPs) |
|---|---|---|
| Particle size | 5–7 nm | 4 nm |
| Concentration | 1,000–10,000 ppm nano silver ions | 150,000 ppm nano copper ions |
| Main application | Mixed into feed | Spread into pond water |
| Main function | Prevents infection from inside as shrimp feed; safe during transport | Sterilizes water, raises ORP, controls Vibrio |
| Preventive dose | 0.05 ppt (mixed into feed) | 0.05 ppm every 7–14 days |
By combining both products, farmers close two gaps at once: pathogens entering through feed, and pathogens multiplying in the water column.
How Nano Silver and Nano Disinfektan Fight Vibrio
Nano silver and nano copper particles work through a layered mechanism: they physically penetrate the pathogen's cell membrane, inhibit enzyme activity and energy (ATP) production, trigger reactive oxygen species that damage bacterial DNA, and ultimately denature cell proteins, killing the pathogen completely. Because this attack happens at multiple points — not through a single mechanism like antibiotics — the nanotechnology doesn't trigger bacterial resistance, while remaining effective against Vibrio, WSSV virus, and EHP/Nosema spores.
Field-Proven Results
FisTx's Nano Disinfektan has been tested at multiple commercial ponds. At a shrimp pond in Pasuruan, routine application kept total Vibrio levels below the safe threshold (<10%) throughout the entire farming cycle. In a feed-additive trial with partner PT MEN, one pond recorded a drop in pathogenic Vibrio Green from 38,700 CFU/ml to 0 within just 10 days of evaluation. A farmer in Kulon Progo, who had been experiencing high mortality since DOC 30, was able to restore pond conditions and complete harvest at DOC 120 with size 28, totaling 9.5 tons.

Safe for Shrimp, Easy on the Wallet
FisTx's internal LD-50 testing showed a safety margin of up to 710 times between the operational dose (0.05–0.2 ppm) and the toxic threshold (LC50 35.5 ppm) — meaning the normal usage dose is far below the level that could harm shrimp. In terms of cost, Nano Disinfektan is recorded as more than 87% cheaper than kaporit for an equivalent volume of disinfection, since its effective dose is much smaller despite its high active concentration.
Frequently Asked Questions About FisTx Aquaculture Nanotechnology
Is Nano Silver safe to mix into shrimp feed?
Yes. FisTx Nano Silver has a neutral pH (8) and is specifically designed to be mixed into feed at a preventive dose of 0.05 ppt, making it safe for regular consumption by shrimp without disrupting their life processes.
What is the Nano Disinfektan dose for a shrimp pond?
The preventive dose of FisTx Nano Disinfektan (nano copper) is 0.05 ppm every 7–14 days, and the treatment dose is 0.1 ppm every 3 days until mortality drops significantly, adjusted to the pond's actual water volume.
What's the difference between nanotechnology and ordinary chemical disinfectants like kaporit?
Conventional disinfectants work on the cell surface and tend to cause irritation with a short protection duration. Nanotechnology penetrates directly into the pathogen's cell structure at the nanometer scale, resulting in higher efficacy, smaller usage doses, and a much lower risk of bacterial resistance.
