In traditional aquaculture, aeration was often seen as just a supporting part of the farming process. Most attention was placed on water conditions and farming methods. But with the rise of high-density farming, Recirculating Aquaculture Systems (RAS), and industrial aquaculture, oxygen supply has become one of the key factors affecting productivity and profitability.

During hot weather, rainy days, or nighttime low-oxygen periods, dissolved oxygen levels can drop quickly. This may reduce feeding activity, slow growth, and in serious cases, cause large-scale fish or shrimp losses.

Why Traditional Aeration Is No Longer Enough

Traditional paddlewheel aerators and air blowers mainly inject air into the water. However, air contains only around 21% oxygen.

In modern high-density aquaculture environments, this can lead to problems such as:

• Low oxygen utilization efficiency
• Uneven dissolved oxygen levels
• Unstable oxygen supply at night
• Higher energy consumption

In high-temperature conditions, water naturally holds less oxygen, making the risk even greater.

Why Efficient On-Site Oxygen Generation Matters

Compared with traditional aeration methods, on-site oxygen generation systems (PSA/VPSA) can continuously provide high-concentration oxygen and improve oxygen dissolution efficiency in water.

A stable oxygen supply can help farms achieve:

• More stable dissolved oxygen levels
• Higher farming density
• Healthier growth conditions
• Lower long-term operating costs

These factors can directly affect both production output and seafood quality.

Modern Aquaculture Is Entering the Era of Systematic Operation

As the global aquaculture industry moves toward smarter and greener development, precise oxygen management is becoming increasingly important.

Oxygen management is no longer just an equipment issue.
It is becoming part of the overall capability of modern aquaculture systems.

In the future, farms that can manage oxygen more efficiently and more reliably will have a stronger advantage in sustainable growth.
