How to Choose Aquaculture Aeration System？
The selection of an aeration system is very important and is key to increasing yields in commercial aquaculture.
We typically select appropriate aquaculture aeration systems based on the following factors:
Contact us for support* Choose based on whether you are farming fish or shrimp.
* Choose based on the aquaculture system model.
* Choose based on whether it is a high-value aquaculture species.
* Choose based on the performance and price of the aquaculture aeration equipment.
Different aeration systems are chosen for fish farming and shrimp farming.
The focus of aeration systems for fish farming ponds
Because fish swim very fast, in aquarium systems, we focus more on the total aeration volume rather than the individual values at a single point in the fish farming pond.
Therefore, we need to choose aerators with high flow rates, such as root blowers or large ring blowers, combined with nano-aeration pipes and nano-aeration discs. This continuously generates a large number of small bubbles in the fish pond, which improves dissolved oxygen and air utilization efficiency.
✅This method improves air utilization by more than 70% compared to directly using perforated PVC pipes for aeration. This high-flow-rate air blower + nano-aeration pipe system is one of our recommended aeration systems.
The focus of aeration systems for shrimp farming ponds
Shrimp swim much slower than fish. In shrimp farming systems, while ensuring sufficient total population, we focus more on ensuring uniform aeration at every point in the shrimp pond.
Shrimp ponds are typically designed for a lower water depth, usually 80-110cm. The shallower the water, the lower the required aeration pressure. Shrimp ponds require less aeration pressure than fish ponds.For the same aeration volume, shrimp ponds require less pressure than fish ponds. At the same aeration volume, without considering higher pressure, a ring blower is more competitive than a root blower.
✅We highly recommend using a ring blower for shrimp pond aerators. This provides greater aeration in shallow water environments and is also less expensive and easier to install.
Choose an aeration system based on different aquaculture systems.
Air Blower Aeration System for Biofloc Fish and Shrimp Farming
Using the Biofloc Technology in aquaculture creates a relatively enclosed space that requires a large number of ammonia-oxidizing and nitrite-oxidizing bacteria (NOBs) to decompose ammonia nitrogen and nitrite in the fish or shrimp ponds.
Both nitrifying and nitrite-oxidizing bacteria are aerobic bacteria, and their rapid reproduction requires very high aeration rates.
In the Biofloc system, high-flow-rate ring blowers and root blowers are the best choices for aquaculture aeration systems.
Aeration System for Flow-Through Aquaculture System
- The Flow-Through system is an intensive land-based aquaculture system. In this system, we aim to achieve relatively higher yields with less land, and the yield can be stably controlled.
- Unlike Biofloc and Ras systems, the Flow-Through system does not use biological filtration. Therefore, we only need to focus on the dissolved oxygen level in the aquaculture tank.
- Furthermore, this system typically raises fish with low dissolved oxygen requirements, so a dissolved oxygen level of 5ppm-7ppm is sufficient.
We recommend two aeration systems for the Flow-Through system.
- For small-scale systems, a ring blower alone is sufficient. By designing a reasonable number of blowers and selecting appropriate end-of-line aeration accessories, the overall dissolved oxygen requirements of the fish and shrimp tanks can be met.
- For large-scale systems, we recommend using root blowers.
- Aquaculture-specific root blowers have advantages in high-power applications and can be equipped with inverters to save electricity.
Aeration System for RAS Systems
RAS systems are highly intensive aquaculture systems, often requiring high-density farming in a small space. The goal in these systems is yield per unit volume, or stocking density per cubic meter of water.
In RAS, the aquaculture aeration system comprises two parts:
- The first part provides oxygen to the fish and shrimp tanks, ensuring sufficient dissolved oxygen levels.
- The second part provides oxygen to the biological filtration system, similar to bioflocculation technology, as nitrifying and nitrite-oxidizing bacteria require more oxygen to thrive.
For RAS systems, we recommend only two aeration systems:
- For low-investment RAS systems, a root blower can be used alone. By carefully designing the piping and end-point air diffusers, the aeration needs of the tanks and biological filtration system can be met.
- For high-investment RAS systems, we recommend using an air system combined with a pure oxygen system.
- The air system is used for aeration in the biological filtration tanks; either a root blower or a ring blower can be selected depending on the scale.
- The pure oxygen system is used for aeration of the aquaculture tank and can stabilize the dissolved oxygen level to 7ppm-10ppm.
Selection of Aquaculture aeration systems for High-value species: Oxygen generator for Salmon farming
High-value species like salmon require high dissolved oxygen levels.
Salmon farming demands high dissolved oxygen levels in the water, ideally above 6 mg/L. Many high-density farms require dissolved oxygen levels of at least 9 mg/L. Like largemouth bass, salmon are carnivorous and can be farmed artificially and fed pelleted feed. Both require high dissolved oxygen levels, with artificial high-density farming environments needing 7-9 ppm.
Comparison of two types of oxygen machines for fish farming:
In our largemouth bass rasa farming project, we conducted a comparative experiment using two fish tanks, both at a stocking density of 60 kg/m³. One tank used a pure oxygen system throughout the entire process, while the other used an air system.
- Fish in the pure oxygen system reached 500g in 150 days, while those in the air system took 180 days.
- The vitality of the bass in the two different systems was also significantly different.
- The feed utilization rate of a pure oxygen system is almost 100%.
Recommended Use of Pure Oxygen Systems:
For high-value aquaculture species, we highly recommend using a pure oxygen generator paired with nano-ceramic discs to maintain a stable high level of dissolved oxygen in the water.
Advantages of Pure Oxygen Generator + Nano-Ceramic Discs:
- Simple installation: Installation can be completed by only 1-2 people.
- Flexible control: The total oxygen flow rate for each fish tank can be controlled individually, as can the flow rate of each ceramic aeration disc.
- Energy saving: At different stages of fish and shrimp farming—seedling stage, growth stage, and maturity stage—the oxygen requirements vary for the same stocking quantity. We can save electricity by flexibly adjusting the oxygen flow rate.
- Biological isolation: Biological isolation is crucial for the future development of aquaculture. Each aquaculture tank can use an independent filtration and oxygenation system. This aeration method is one of the basic requirements for an independent RAS unit.
Other Aeration and Oxygen Control for Aquaculture: Pure Oxygen Generator + Oxygen Cone Aquaculture:
- This is a traditional pure oxygen connection method. Oxygen and water are pressurized and mixed inside the oxygen cone, and finally delivered to each aquaculture tank by the circulation system. We do not recommend using this method:
- Lack of Flexible Control
This method is like a large system where the flow rate of the entire system is pre-designed. If I adjust the overall value, it will affect all aquaculture tanks. - No Bioisolation
A series-connected aquaculture system cannot achieve bioisolation, making it easy for bacteria and viruses to spread. - Higher Energy Consumption
Oxygen cone aquaculture requires the addition of high-power circulation pumps and pressurization pumps. We can completely convert this energy consumption to the oxygen generator itself.

Importance of Dissolved Oxygen In Aquaculture
Fish and shrimp consume oxygen in water. In nature, this is a balanced state.
However, in aquaculture, we need to increase production to achieve economic benefits.
More fish and shrimp require more dissolved oxygen in the water, necessitating the addition of aquaculture aeration systems.
In commercial aquaculture, we typically use aerators to increase dissolved oxygen. Aerators are divided into air aerators and pure oxygen generators, which produce air and pure oxygen, respectively, then deliver these gases into the water through pipes and air diffusers.
Choosing suitable aquaculture aeration systems is crucial:
1. Increased production and improved aquaculture efficiency.
Traditional outdoor fish ponds without aeration systems generally have stocking densities below 10 kg/m³, while modern aquaculture using air aeration systems can easily reach 30 kg/m³, and with pure oxygen systems, even exceeding 100 kg/m³.
2. Improved feed utilization and reduced production costs.
In low-oxygen environments, the appetite of fish and shrimp decreases. When we feed fish, a significant amount is wasted, sometimes exceeding 50%. This wasted feed not only increases costs but also further pollutes the water.
Using an aeration system, while increasing electricity costs, improves feed utilization to over 90%.
3. Reduces fish disease incidence and simplifies aquaculture.
In low-oxygen environments, fish and shrimp are unhealthy, making them more susceptible to diseases like water mold, intestinal diseases, and respiratory illnesses.
Using aquaculture aeration systems maintains dissolved oxygen levels within a suitable range, greatly increasing the activity of fish and shrimp. Many diseases are even prevented from occurring.
