Shrimp farming continues to be one of the most dynamic and lucrative sectors in aquaculture. However, the intensification of production has brought along a set of persistent challenges: high mortality, disease outbreaks, water quality fluctuations, and the need to reduce chemical use without compromising performance.

In response to these challenges, nanobubble technology has emerged as a promising solution. With the ability to increase dissolved oxygen, promote microbial balance, and support chemical-free disease control, nanobubbles are gaining traction among forward-thinking shrimp farmers worldwide.

This article highlights real-world case studies from different geographic regions and farming systems, demonstrating how nanobubbles are transforming shrimp aquaculture on the ground.

Case Study 1 – Thailand: Improving Survival in High-Density Ponds

Location: Samut Sakhon, Thailand
System: Lined earthen ponds
Species: Whiteleg shrimp (Penaeus vannamei)

Challenge:

High mortality in early growth stages due to low nighttime oxygen in ponds stocked at 70 shrimp/m².

Intervention:

A nanobubble oxygen system was installed to operate automatically during night hours, with micro-diffusers positioned to optimize deep water circulation.

Results:

• Nighttime dissolved oxygen (DO) remained 50% higher on average.

   

• Early-stage mortality dropped from 20% to 6%.

   

• Feed conversion ratio improved by 13%.

   

• The grow-out cycle was shortened by 4 days, allowing an additional crop annually.

   

Takeaway:

By stabilizing oxygen levels without oversaturation, nanobubbles reduced stress and supported consistent growth across the entire population.

Case Study 2 – Ecuador: Natural Disease Control Against Vibrios

Location: Guayas Province, Ecuador
System: Semi-intensive outdoor ponds
Issue: Frequent outbreaks of Early Mortality Syndrome (EMS) caused by Vibrio parahaemolyticus

Intervention:

Daily water exchange (10%) using nanobubble-treated water, along with weekly reactive oxygen species (ROS) dosing using a specialized nanobubble generator.

Results:

• Vibrios reduced by 65% in water samples over 3 weeks.

   

• No EMS-related mortality recorded during the trial period.

   

• Total elimination of chemical antibiotics and disinfectants.

   

• The facility achieved GlobalG.A.P. audit readiness faster.

   

Takeaway:

Nanobubbles enhanced water biosecurity through oxidative disinfection while preserving the beneficial microbiota in the pond ecosystem.

Case Study 3 – India: Reducing Winter Stress and Improving Feed Uptake

Location: Andhra Pradesh, India
Issue: Cold-season temperature drops led to lower DO and reduced shrimp activity.

Intervention:

Nighttime nanobubble aeration was deployed from November to February. The system delivered ultra-fine oxygen-rich bubbles directly into pond bottoms, where DO drops were most severe.

Results:

• DO levels remained stable despite temperature fluctuations.

   

• Feed consumption increased by 11%.

   

• Survival rates improved from 72% to 88%.

   

• Farmers reported a 25% higher harvest volume during winter.

   

Takeaway:

By minimizing hypoxia-related stress, nanobubbles improved both immunity and metabolic efficiency in low-temperature conditions.

Case Study 4 – Turkey: Enhancing Water Quality in Indoor RAS Shrimp Systems

Location: Mersin, Turkey
System: Indoor Recirculating Aquaculture System (RAS)
Problem: Buildup of sludge, foul odor near biofilters, elevated ammonia levels.

Intervention:

Nanobubble-infused water was introduced at biofilter inlets. Additionally, targeted ROS treatments were applied twice a week to reduce organic accumulation.

Results:

• Ammonia and nitrite levels dropped by 40%.

   

• Biofilter cleaning frequency reduced by 30%.

   

• Strong odor complaints eliminated by staff.

   

• Shrimp showed improved color and activity levels.

   

Takeaway:

In closed-loop systems, nanobubbles helped maintain system hygiene, improved microbial stability, and reduced operational stress.
