Nano-Tube Ring is better DO

Nano-Tube Ring is designed to optimize the use of Nano-Tube. Nano-Tube provides a quick and easy solution to carry oxygen, carbonate (O2, CO2, …) into your system. If you connect simply the Nano-Tube with our accessories, you will enjoy the high efficiency from Nano–Tube aeration technology

Nano-Tube Ring Diffuser
Improve dissolved oxygen level

Nano-Tube Ring is oxygen transfer efficiency

Nano-Tube Ring transfers oxygen into the environment effectively thanks to broad diffuser area, special designed equipment to provide oxygen to the shrimp, fish ponds with high density…

Nano-Tube Ring improves high stocking

To improve productivity in a small area, reduce production costs, we should apply new techniques in shrimp ponds. Nano-Tube Ring allows breeding with higher density, feeding more often, reducing FCR.

Reducing FCR for shrimp

Advantages of Nano-Tube

Reduce power costs up to 75%
No moving parts, low depreciation
Maintain high dissolved oxygen level
Allow higher density
Allow higher stocking rate
Allow feed more often
Grow faster and reduce FCR
Low initial investment costs

Advantages of Nano-Tube Ring

Install simply and quickly
Suitable for all types of ponds
Clean and service easily

Nano-Tube Ring Applications

When the oxygen content is low, the shrimp will eat less or eat slowly, leading to excess food in the pond. This will change the elements of water quality and accumulate toxic gases. These factors will impact back the shrimp making them weakened and susceptible to diseases caused by bacteria, especially white feces.

System of Nano-Tube diffusion plates meet various criteria, from simple to complex, intensive shrimp to super intensive shrimp management, indoor shrimp farming, Biofloc technology, raceway system, nursery, farming tilapia, farming fish in cages…

With insight, scientific and rational approach, constant experience over time, our diffuser system gives you superior performance, convenient and fast installation.

Earthen shrimp ponds

Earthen shrimp ponds

When the DO of the water is low, the shrimp’s growth rate is slow and the feed conversion ratio (FCR) is very high. It takes longer to raise a batch of shrimp than when the DO is sufficient. Excess feed causes a build up of waste materials in the pond, which encourages the growth of disease-causing Vibrio bacteria. When the oxygen or DO level in the pond drops over the course of the culture period, the shrimp are likely to get sick, special with white feces disease.

Geomembrane shrimp farming

Lined shrimp farming

The most appropriate DO for shrimp health and normal growth is from no less than 4 mg/l (ppm) up to the saturation point. For shrimp culture it is best to maintain the DO at 6-8 mg/l, or no less than 4 mg/l all the time. In reality, on most farms the DO only stays this high during the first month or two of the culture period. On some farms, once the shrimp are 30 days old the night time DO, from about midnight to early morning before dawn, goes down to less than 3 ppm.

Intensive shrimp farming

Intensive shrimp farming

Farms that are successful in keeping the DO at no less than 4 ppm even in the morning are usually very successful, with good growth rates, a high survival rate and a low FCR. When the DO is maintained at at least 4 ppm, there is seldom a problem with white feces disease or bacterial infections. In contrast, on farms where the DO drops below 4 ppm at night, the shrimp will grow slowly during the culture period and white feces disease is very common.
