The metabolic rates of fish can be severely affected by the concentration of oxygen in a rearing environment. Suppressed dissolved oxygen levels lead to decreased respiration and feeding activity that slows fish growth rates. It can also lead to disease and fungal infections. If correctly applied, oxygen supplementation ensures that fish and seafood farmers can achieve the highest possible survival rates under optimum breeding conditions to boost yields and profits.
Guidelines for Dissolved Oxygen Levels
|General Effects on Fish|
|85%||No negative effect|
|65%||No appetite, possible mortality|
|45%||No appetite and high mortality|
The UFB generator is an essential complement to any aquaculture operation. Our UFB systems produce trillions of nanobubbles in the 70-200 nm range, delivering more than 200-times the interfacial surface area compared to microbubbles. Oxygen is transferred into the water with up to 99% efficiency, providing maximum utilization potential via a battery reserve of nanobubbles suspended in the water. This low turbulent, UFB oxygen diffusion creates a higher and more stable saturation level of oxygen that mitigates the risk of sudden DO drops during the night.
Ultra Fine Bubbles have unique characteristics. Due to their minute size and high internal pressure, they can remain stable in water for prolonged periods of time. Unlike a microbubble that rises and bursts on the surface very quickly, nanobubbles have minimal buoyancy and can disperse throughout a body of water due to the principals of Brownian motion (see Uniqueness of USB Technology) They can also be injected at any level and provide oxygenation at all depths.
Emergency oxygen injection with our UFB generators has proven to be effective in the event of breakdowns in traditional aeration systems. The mobility and versatility of our UFB systems allow them to practically and economically compensate for oxygen shortfalls.
