Since the dissolved oxygen in the pond is uniform, and high throughout the pond, and the cost of operating is low, AirOxi tube should be used from before the stocking of seeds, to ensure that from day 1 the pond oxygen levels are high.

When such care is taken, it is observed that survival increases in all kinds of ponds – mud, PE lined, concrete ponds, nurseries, etc.

And the immunity improves due to good health of the seeds in the early stages of development

At most places where AirOxi tube is installed, farmers have said that they have found to be 30-40% higher per hectare, than in the nearby ponds of the same farmer where other traditional methods were used for aeration.

Availability of good DO

Increase in survival, increase in immunity and higher stocking density possible due to good DO are the main reasons for this

Traditional aeration methods splash up water in the air using paddles or other devices. When these drops of water come down, they dissolve oxygen in them. In Airoxi™ tube system, because oxygen dissolves through the diffusion process, small bubbles rising up in the water and dissolving oxygen, The Standard Oxygen Transfer Rate (SOTR) is 3 times that of paddle aerator. Hence Oxygen dissolves 3 times faster than with paddle aerators. For example – if it takes 1 hour to increase the DO from 4 to 5 mg/ L using paddle aerators, this will happen within 20 minutes using AirOxi™ Tube. The SAE – Standard Aeration Efficiency – is 3 times that of traditional paddle aerator. So power required is just 1/3rd. If for example you need 20 HP of power to aerate 1 hectare of aquaculture pond, the power required using AirOxi™ Tube will be just 5 HP.

Airoxi™ tube requires less power to aerate similar size ponds. In traditional methods, more motors are required to splash water. For example, if each paddle is powered by 2 HP of motor, and you are using 6 such paddles per hectare, that means you are using 12 HP of motors for one hectare. Whereas for one hectare of Airoxi™ pipe you may not need more than 3 HP size of the blower. This may translate into almost 60% to 70% saving in power.

Since Airoxi™ tube installations do not splash water, they do not disturb the fish and shrimp and they make very less noise. AirOxi Tube system can be operated 24/7 - any time of day or night. Even during feeding time. As a result, you can get higher oxygen content, even early in the morning around 4.00 am, when the natural dissolved oxygen is lowest.

Airoxi™ tube is installed at the bottom or almost bottom of the pond. It is not restricted to just the surface. So the dissolved oxygen is available uniformly from bottom to top oxygen is available faster to aquatic life at depths.

Also, Airoxi™ tube can be installed all through the pond, even going to the middle. It is not restricted only on the edges / border of the pond or within feeding lines. Hence oxygen can be dissolved deeper all across the pond. You get uniform dissolved oxygen all across the pond.

AirOxi tube system ensures that sufficient Dissolved Oxygen is available throughout the pond and at all times. As a result, all pond life including probiotics, algae, plankton and all other marine life grow well. No wonder that AirOxi Tube system is the choice of farmers when they plan a bio-floc or waterway based aquafarm.

With rising costs and volatile market prices for sea food, keeping costs low is essential. The cost per ton of sea food can be reduced marginally by reducing inputs. But still there will be costs which cannot be reduced like the cost of electricity, pond preparation, feed, seed, minerals and medicines, etc. The only way to reduce this is to increase stocking density and total bio mass harvested from the pond.

Feed, minerals, probiotics and medicines can be added as required. But the biggest obstacle to increasing output and bio mass is dissolved oxygen in the pond. That cannot be added externally like feed and supplements. It needs to be managed well and with its high efficiency low cost diffused aeration system, AirOxi Tube system is the preferred choice of aquaculture farmers for increasing their stocking density.
