Introduction — Why AirOxi Matters for IPRS

Intensive Pond Raceway Systems (IPRS) push aquaculture toward higher stocking densities and stricter water quality control. In such systems, reliable dissolved oxygen (DO) management becomes the single most critical factor for survival, growth, and feed efficiency.

AirOxi tubes are a specialized aeration solution — porous micro-bubble tubing, diffusers, and plug-and-play aeration sets designed for commercial aquaculture. They provide consistent oxygenation, flexible deployment options, and relatively lower energy demand compared to many mechanical aerators.

How AirOxi Works in IPRS

AirOxi tubes release extremely fine bubbles along their length through engineered micro-pores. When installed in IPRS raceways (as floor grids, wall lines, or diffuser manifolds), they create a distributed curtain of bubbles that:

·        Increase oxygen transfer efficiency by maximizing water–air contact time

·        Generate gentle upward water movement to reduce dead zones

·        Allow modular layouts to match raceway geometry and flow rates

·        Because aeration is evenly distributed, operators can avoid localized supersaturation and reduce dependence on high-power paddlewheel or jet aerators in many cases.

·       

Key Benefits for IPRS Operators

1. Stable Dissolved Oxygen

Micro-bubble diffusion maintains uniform DO levels across the raceway, reducing stress and mortality at high stocking densities.

2. Energy Efficiency

When paired with suitable blowers (such as root blowers or multi-stage blowers), AirOxi systems can deliver higher oxygen transfer per watt compared to large paddlewheel aerators operating continuously.

3. Modularity and Retrofit-Friendly

AirOxi tubing can be installed as floating grids, floor lines, or side-mounted runs. This makes upgrading existing raceways simple and cost-effective.

4. Lower Maintenance Options

Certain AirOxi variants are manufactured with algae-resistant formulations to minimize fouling in ponds with heavy biofilm formation.

Practical Installation Tips for IPRS

Match the Blower to the Layout

AirOxi tubes perform best with root blowers for higher pressure requirements, especially on longer pipe runs. Always follow manufacturer recommendations for maximum run length and compatible blower types.

Design Smart Grids

In raceways, install parallel lines spaced evenly to ensure consistent DO coverage. In long, narrow raceways, multiple shorter loops are preferable to one long run, as this reduces pressure drop and ensures uniform bubble output.

Ensure Accessibility

Keep manifolds and inlet valves accessible for inspection and cleaning. Use manifolds or spider bases for compact multi-line connections, especially in corners.

Monitor Continuously

Combine AirOxi with continuous DO monitoring systems and alarm setups. While fine-bubble systems are highly efficient, real-time monitoring is essential in intensive aquaculture operations.

Measurable Outcomes Reported by Operators

IPRS operators using AirOxi commonly report:

·        Reduced mortality during feeding peaks and temperature stress

·        Improved feed conversion ratios (FCR) due to stable oxygen levels

·        Lower peak power consumption compared to running multiple high-horsepower paddle aerators continuously

Common Aeration Questions Shrimp Farmers Ask – Answered Simply

 

Aeration is one of the most discussed—and misunderstood—topics in shrimp farming. Most farmers don’t search for product names or technologies. They search for solutions to problems they see in their ponds.

This blog answers the real questions shrimp farmers ask about aeration in nurseries and grow-out ponds.

---

Why Do Shrimp Gather Near the Pond Edge or Surface at Night?

This usually happens due to low dissolved oxygen (DO) in the pond, especially near the bottom.

At night:

• Algae stop producing oxygen
• Shrimp respiration increases
• Organic waste consumes oxygen near the pond floor

If oxygen is only available at the surface, shrimp move upward or toward aerators to survive.

Bottom aeration helps maintain oxygen where shrimp live, preventing this behaviour.

---

Is Surface Aeration Enough for Shrimp Farming?

Surface aerators mainly:

• Oxygenate the top layer of water
• Create strong currents near the machine
• Leave the pond bottom under-aerated

For low stocking densities, this may be sufficient.
For nurseries, biofloc systems, or intensive grow-out ponds, surface aeration alone is usually not enough.

Bottom-level oxygen supply is critical as biomass increases.

---

Why Does My Pond Bottom Turn Black and Smell Bad?

A black, foul-smelling pond bottom indicates:

• Low oxygen at the bottom
• Formation of anaerobic conditions
• Presence of toxic gases like hydrogen sulphide (H₂S)

This often leads to:

• Poor shrimp growth
• Weak moulting
• Sudden mortality

Aeration that reaches the pond bottom prevents these conditions by keeping the soil aerobic.

---

How Can I Improve Oxygen at the Pond Bottom?

To improve bottom oxygen:

• Use aeration systems that release air near the pond floor
• Ensure oxygen is distributed evenly across the pond
• Avoid relying only on high-turbulence surface aerators

Fine air bubbles rising slowly from the bottom improve oxygen transfer and circulation without stressing shrimp. More info https://airoxitube.blogspot.com/2025/02/what-is-ideal-aeration-setup-for-shrimp.html

---

Why Is Aeration More Important in Shrimp Nurseries?

Nurseries have:

• Very high stocking density
• High feeding frequency
• Rapid waste accumulation

Young shrimp stay close to the bottom and are sensitive to:

• Oxygen fluctuations
• Strong water currents

Gentle, uniform aeration near the bottom improves:

• Survival rate
• Growth uniformity
• Stress resistance during moulting

---

Can Too Much Aeration Stress Shrimp?

Yes.

Excessive or poorly designed aeration can:

• Create strong currents
• Increase shrimp energy loss
• Cause physical stress or injury

Effective aeration should:

• Supply oxygen evenly
• Maintain gentle circulation
• Avoid disturbing feeding and resting behaviour

More turbulence does not always mean better oxygenation.

---

Why Does Feed Waste Accumulate Even with Aerators Running?

This happens when:

• Aeration is concentrated in one area
• Pond circulation is uneven
• Bottom zones remain stagnant

Proper aeration helps:

• Prevent sludge compaction
• Keep organic matter from settling excessively
• Make siphoning and waste removal easier

Even oxygen distribution is key, not just aerator power.

---

Is Bottom Aeration Useful in Grow-Out Ponds?

Yes, especially during:

• Mid to late culture stages
• High biomass periods
• Nighttime and early morning hours

Bottom aeration helps:

• Maintain stable DO during peak demand
• Improve feed conversion ratio (FCR)
• Reduce disease risk linked to poor pond conditions

Many farms combine bottom aeration with surface aerators for best results.

---

Does Better Aeration Reduce Shrimp Disease?

Indirectly, yes.

Good aeration:

• Prevents toxic gas formation
• Improves pond hygiene
• Supports beneficial microbial activity
• Reduces stress on shrimp

Lower stress and cleaner pond bottoms result in better immunity and survival.

---

Is Aeration Power Consumption Always High?

Not necessarily.

Efficient aeration depends on:

• Bubble size
• Air distribution method
• Coverage area

Systems that distribute air evenly using fine bubbles often achieve:

• Higher oxygen transfer efficiency
• Lower energy consumption per kg of shrimp produced

---

What Is the Best Aeration Strategy for Shrimp Farming?

There is no single aerator that fits all farms, but the most effective strategy usually includes:

• Uniform oxygen distribution
• Oxygen availability at the pond bottom
• Gentle circulation suitable for shrimp behaviour
• Scalable aeration as biomass increases

Farms that focus only on surface oxygen often face problems later in the cycle.

---

Final Thoughts for Shrimp Farmers

If you are facing issues like:

• Low DO at night
• Black pond bottoms
• Uneven shrimp growth
• High FCR
• Sudden mortality during peak biomass

The problem is often not lack of aerators, but how and where oxygen is delivered.

Improving bottom-level oxygen and uniform aeration can dramatically improve pond performance in both nurseries and grow-out systems.
