Raise Healthier Fish with Oxygen Nanobubbles

The survival and overall health of fish depend on their access to oxygen. Incorporating nanobubbles technology into the water system enhances oxygen dissolving capacity. This readily available oxygen supply minimizes fish stress, boosts feed conversion ratios, and supports the development of robust immune systems, promoting overall healthier fish.

Faster Growth

Nanobubbles can promote fish growth by improving the water quality in aquaculture systems. The improved oxygen availability helps to reduce fish stress, enhance their immune system, and increase their appetite, leading to more rapid growth.

Decreased Fish Mortality

In addition to increasing yields and promoting growth, nanobubbles can decrease rates of illness and mortality in aquaculture. The improved oxygenation and circulation provided by nanobubbles can create an environment that is less conducive to the growth of harmful bacteria and viruses, reducing the risk of disease outbreaks.

Increased Ratio of Hatching

The bubbles' tiny size and prolonged oxygen supply improve growth and survival of hatched fry, prevent suffocation and boost hatching success. Nanobubbles create an optimal environment for healthier aquatic species.

Increased Fish Size and Weight

Studies conducted in aquaculture operations have shown that using nanobubbles can result in a 15% increase in weight and a 9% increase in length, compared to control groups.

Reduced Harvest Time & More Cycles

By increasing oxygenation and circulation, nanobubbles enhance fish metabolism, allowing them to grow faster and reach market size more quickly. This reduction in harvest time translates to quicker time to market and increased sales for aquaculture customers.

Aquaculture Case Study

Aquaculture Case Study:

Explore some of the benefits of converting to nanobubble technology at an intensive aquaculture customer. 

The Environment:

This customer's setup utilized an on-site well to pump water into a 4-meter (12-foot) high holding tank. Gravity alone then delivered a consistent flow of fresh water to their numerous ponds and tanks, eliminating the need for additional pumps. While water flow rates varied by tank size, the pressure remained stable at around 0.2 bars at the water discharge points.

The Challange:

Customer desired a nanobubble aeration system, but their existing water pressure (3-4 PSI) fell short of what typical systems required.  Traditional solutions wouldn't work.  Trident stepped up to the challenge: designing a system that could function on this low pressure while still achieving an impressive >85% gas transfer efficiency for their tanks.

The Outcome:

  • Reduced oxygen utilization by >50% over Microbubble Stones

  • Zero additional power consumed, and no water pumps were used.

  • Visible water clarity, reduced solids content, and nitrogen gas removal.

  • Uniform oxygenation all-around the tank.

  • Low pressure discharge prevented any water turbulence inside the tank.

Overall Benefits

Financial Boost and Healthier Fish:

A double win with Trident nanobubble technology.

Reduced Oxygen Costs: Lower oxygen usage translates to operational savings (OpEx) due to less oxygen demand. This also allows them to right-size their oxygen supply and storage, further minimizing ongoing costs. The combined impact will  significantly reduce the payback period (ROI) of the nanobubble generator to mere months.

Cleaning The Ecosystem:  Nanobubbles also brought immediate results with cleaner tanks within just two days. This impressive clarity is attributed to the nanobubbles' ability to gently float organic matter to the surface, improving water quality for the fish.  Cleaner environments will lead to lower fish mortality rates and reduced stress, contributing to their overall success with implementing nanobubble technology.
