At first glance, hydroponic farming and fisheries seem like completely different worlds.
One grows plants without soil. The other raises fish in water.
But underneath the surface, they share a surprisingly important dependency:
oxygen.
And not just oxygen in the air around them — dissolved oxygen (DO) in the water.
For hydroponic growers, oxygen availability around the roots can influence the growing environment. For fish farmers and fisheries, dissolved oxygen is fundamental to the environment their fish live in.
This is where nanobubble technology starts to become interesting.
It’s Not Just About Adding Oxygen
When people think about increasing dissolved oxygen, the obvious answer is usually simple: add more oxygen.
But getting oxygen into water efficiently — and keeping it there — is a different challenge.
Large bubbles rise quickly to the surface and release their gas into the atmosphere. Nanobubbles behave differently because of their extremely small size and large surface area relative to their volume.
Instead of simply pushing oxygen through the water, nanobubble technology is designed to create an enormous gas-to-water interface.
More interface means more opportunity for gas transfer.
IGS Water’s nanobubble generator produces ultra-fine nanobubbles designed to remain in the water longer than conventional larger bubbles, helping maintain elevated dissolved oxygen levels.
And that can be valuable in both plant and aquatic production.
Hydroponics: Your Roots Are Living in the Water
In a hydroponic system, the roots don’t have the same access to oxygen that they would have in conventional soil.
The plant may look healthy above the surface, but what is happening around the root zone is a completely different story.
The root environment needs the right balance of water, nutrients and oxygen.
When oxygen availability becomes limited, the root zone can become an increasingly difficult environment for plants.
This is why oxygen management deserves more attention in hydroponics.
By introducing oxygen nanobubbles into the nutrient solution, IGS NB can help increase dissolved oxygen availability throughout the system.
The goal isn’t simply to make the water “more oxygenated.”
It’s about creating a better environment around the roots.
That can support:
- Healthier root-zone conditions
- Stronger root development
- More consistent oxygen availability
- Better conditions in recirculating systems
- More efficient use of the growing environment
For commercial hydroponic operations, where the same water may continuously move through the system, maintaining water quality becomes even more important.
Fisheries: Oxygen Is Part of the Habitat
Now move from roots to gills.
Fish don’t have the luxury of leaving their environment when water quality changes.
Their entire habitat is the water.
Dissolved oxygen can fluctuate due to temperature, stocking density, organic matter, algae activity, weather and water movement.
In ponds and larger water bodies, oxygen can also become unevenly distributed.
You might have oxygen-rich water near the surface while deeper areas experience very different conditions.
This is where oxygen distribution becomes just as important as oxygen concentration.
IGS NB creates fine oxygen bubbles that can help distribute dissolved oxygen through the water column, supporting a more uniform aquatic environment.
For fisheries and aquaculture operations, this can help create better conditions for:
- Fish growth
- Aquatic animal respiration
- Water quality management
- Oxygen distribution
- Odour reduction
- High-density production environments
The objective is simple:
Keep the water working for the fish, not against them.
One Technology. Two Completely Different Production Systems.
Hydroponics and fisheries may have different goals, but both depend on managing the water effectively.
Hydroponic growers are trying to create the right environment for roots.
Fish farmers are trying to create the right environment for aquatic life.
In both cases, water is doing much more than simply carrying something from one place to another.
It’s the growing environment.
That’s why improving the quality and oxygenation of that water can have a much bigger role than it first appears.
Why Nanobubbles Instead of Simply Adding More Air?
Traditional aeration can introduce oxygen into water using larger bubbles.
The challenge is that many of those bubbles quickly travel to the surface and release their gas.
Nanobubbles take a different approach.
Because they are extremely small, they have a much greater total surface area compared with the same volume of gas in larger bubbles.
IGS Water’s technology is designed to generate a high concentration of nanobubbles without requiring water circulation through the generator.
This also allows the system to be configured around different applications, from smaller production systems to larger water bodies.
The result is a more flexible approach to oxygen management.
From Root Zone to Fish Pond
The interesting thing about nanobubble technology isn’t that it belongs to one industry.
It doesn’t.
The same basic principle — getting more useful gas into water and maintaining it effectively — can be applied across very different environments.
In hydroponics, that means focusing on the root zone.
In fisheries, it means focusing on the aquatic environment.
In both cases, the water becomes an active part of the production strategy.
And sometimes, improving production doesn’t start with changing the plant or the fish.
It starts with changing the water they’re living in.
