Aquaculture & Restoration

Healthier Fish. Higher Density. Fewer Losses.

Oxygen crashes, disease outbreaks, and ammonia spikes are draining your margins. Our ultrafine bubble systems steady your water mechanically — so your stock thrives, and the chemicals you still use go further.

The Problem

Your Water Is Working Against You

Low dissolved oxygen at the bottom of your ponds and tanks means stressed fish, slow growth, and sudden disease outbreaks. Ammonia builds up, pathogens spread, and every treatment you add creates new problems — antibiotic resistance, chemical residues, and rising compliance costs.

The Solution

Oxygen That Reaches the Bottom

Our ultrafine bubbles don't float and burst like conventional aeration. They stay suspended, delivering oxygen deep into the water column and into the sediment layer. The result: stable dissolved oxygen from surface to bottom, suppressed pathogens, and faster ammonia breakdown — without antibiotics, algaecides, or downtime.

Key Benefits

health_and_safety

Disease Drops, Survival Climbs

A permanently aerobic environment suppresses Vibrio, Aeromonas, and other pathogens at the source. Survival rates jumped from 15% to 75% in infection trials — without antibiotics.

Stock More, Lose Less

Stable dissolved oxygen throughout the water column means you can raise stocking density with far less exposure to oxygen crashes, feed waste, and overnight fish kills.

Cleaner Water, Less Maintenance

Ultrafine bubbles lock phosphorus in sediments, trigger ammonia oxidation, and suppress harmful algal blooms — reducing water changes, sludge removal, and chemical treatments.

The Science Behind the Results

How It Works — With the Research to Back It Up

Every aquaculture operation hits the same ceilings: oxygen crashes, disease pressure, ammonia spikes, and water quality decline. Here's exactly how ultrafine bubble technology breaks through each one — backed by peer-reviewed data.

Figures below are from independent, peer-reviewed studies unless marked KST field data.

Problem: Your Pond Bottom Is Releasing Toxinskeyboard_arrow_down
The Problem: Anoxic sludge at the bottom of your ponds releases ammonia and phosphorus back into the water — fueling algal blooms and stressing your stock, even after you've controlled external inputs. Waters et al., 2022
What We Do: Our ultrafine bubbles reach the sediment layer and activate beneficial bacteria that break down organic muck and lock phosphorus in place. Field trials show phosphorus release reduced by 79–96%.
Yu et al., 2019 Zhang et al., 2020 Zhang et al., 2018
Problem: Algal Blooms Are Killing Your Water Qualitykeyboard_arrow_down
The Problem: Algal blooms deplete oxygen, release toxins, and cloud your water. Chemical treatments are temporary, expensive, and often toxic to the species you're trying to protect.
What We Do: Our systems physically rupture the gas vacuoles of cyanobacteria, stripping their buoyancy so they sink and die. Combined treatments achieve 99% algae destruction in published work — without dosed algaecides.
Li et al., 2015 Wu et al., 2012 Ng et al., 2023
Problem: Disease Outbreaks Are Wiping Out Your Stockkeyboard_arrow_down
The Problem: Bacterial pathogens like Vibrio and Aeromonas cause mass mortality events. Antibiotics are increasingly restricted, build resistance, and leave residues that threaten your market access. Nghia et al., 2022
What We Do: Ozone ultrafine bubbles eliminate >99.99% of bacteria and boost the immune response in your fish. In infection trials, survival rates jumped from 15% to 75% — without antibiotics.
Imaizumi et al., 2018 Linh et al., 2021 Jhunkeaw et al., 2021
Problem: Viral Outbreaks Are Decimating Your Populationkeyboard_arrow_down
The Problem: Fish viruses like Spring Viremia of Carp Virus (SVCV) cause catastrophic losses and are nearly impossible to treat with conventional methods.
What We Do: Hydrogen ultrafine bubbles act as therapeutic antioxidants, reducing viral mortality from 80% to 40% by neutralizing oxidative stress and calming the inflammatory response.
Li et al., 2022 Yaparatne et al., 2024
Problem: Ammonia Is Building Up Faster Than You Can Remove Itkeyboard_arrow_down
The Problem: Ammonia and nitrite buildup is one of the top killers in recirculating aquaculture systems (RAS). Conventional biological filters can't keep up at high stocking densities.
What We Do: Oxygen ultrafine bubbles accelerate nitrifying bacteria activity, removing 70–83% of ammonia within just 45 minutes.
Subhan et al., 2021 Yaparatne et al., 2024
Problem: Your Ponds Are a Source of Greenhouse Gaskeyboard_arrow_down
The Problem: Anoxic pond sediments produce methane — a potent greenhouse gas that's increasingly under regulatory scrutiny and undermines sustainability claims.
What We Do: By delivering oxygen directly to the sediment layer, our ultrafine bubbles activate methane-eating bacteria and suppress methane production. Cumulative emissions reduced by a factor of 3.2×.
Shi et al., 2018 Waters et al., 2022
Problem: Off-Flavors Are Making Your Fish Unsellablekeyboard_arrow_down
The Problem: Blue-green algae produce geosmin and MIB — compounds that give your fish an "earthy" taste and smell. Once it's in the flesh, your harvest is unsellable.
What We Do: Oxygen ultrafine bubbles degrade these off-flavor compounds through advanced oxidation, removing up to 40% of geosmin and 20% of MIB — so your product reaches market without a purging cycle.
Soyluoglu et al., 2022 Foudas et al., 2023
Problem: Your Filters Are Clogging Constantlykeyboard_arrow_down
The Problem: Filtration membranes in water reuse systems clog rapidly from organic fouling, driving up maintenance costs and reducing system uptime.
What We Do: Ultrafine bubbles physically scour membrane surfaces, reducing flux decline from 60% to just 20% over 24 hours — without chemical cleaners.
Farid et al., 2022 Yaparatne et al., 2024
Problem: Parasites and Pests Are Spreading Through Your Systemkeyboard_arrow_down
The Problem: Small planktonic crustaceans and parasites hitch rides through your system, competing for feed and hosting pathogens that put your entire stock at risk.
What We Do: Hydrodynamic cavitation eliminates planktonic pests through mechanical shockwaves — no dosed treatments, no residues, no resistance.
