AQUACULTURE

CONTEXT

Aquaculture is the fastest growing animal-based food industry in the world. More than half of the seafood eaten in Spain comes from farms, and most of it is imported. Population growth and declining natural harvests place the managed aquaculture industry in a prime position for explosive global expansion. In this context, superior water quality management will be key to the ultimate success of the industry.

Dissolved oxygen (DO) is the most important chemical parameter in aquaculture. Low dissolved oxygen levels lead to a greater increase in fish kill, either directly or indirectly, than all other problems combined. Like humans, fish require oxygen to breathe. The amount of oxygen consumed by fish varies based on their size, feeding rate, activity level, and temperature. For example, small fish consume more oxygen than large fish due to their higher metabolic rate.

Fish farmers stock larger amounts of fish in the same body of water to maximize production. Therefore, an increase in oxygen demand occurs. Thus, it is often necessary to provide additional aeration to maintain adequate levels of dissolved oxygen.

For good growth, fish must be raised with optimal levels of dissolved oxygen. As a general rule, DO levels of at least 5 ppm should be maintained. Dissolved oxygen levels below 5 ppm can cause undue stress to fish, and levels below 2 ppm will result in death. It is worth mentioning that warm and cold water species have different tolerances to low DO levels.

Fish are not the only consumers of oxygen in aquaculture systems. Bacteria, phytoplankton, and zooplankton also eat large amounts. But the main consumer of oxygen in aquaculture systems is the decomposition of organic materials such as algae, bacteria and fish waste. Consequently, management of supplemental oxygen is critical.

In nature, oxygen enters water by direct diffusion at the air-water interface and through photosynthesis by plants. Direct diffusion is relatively insignificant unless there is considerable wind and wave action. Various forms of mechanical aeration are currently used to help nature. The general categories are: Paddlewheels, Agitators, Vertical Sprayers, Impellers, Airlift Pumps, Venturi Pumps, Liquid Oxygen Injection and Air Diffusers.

NAECOER offers a new, more efficient and more effective technology for maintaining DO levels in aquaculture operations using nanobubble generation.

WHY IS TECHNOLOGY NECESSARY NAECOER?

OXYGENATION TECHNOLOGY NAECOER

nanobubble technology NAECOER It has two components that allow it to create higher DO levels, up to ten times more than can be achieved with conventional technologies.

– The introduction of 97 percent pure oxygen to the water.
– The nanobubbles patent NAECOER .

Nanobubbles possess unique properties. First of all, they have a long shelf life as they remain relatively stable for seventy days. They also have a high solubility of the gas in the liquid due to its high internal pressure. Scientific studies have shown that nanobubbles significantly increase the concentration of dissolved oxygen in water. As a result, there is an increase of more than thirty percent of the oxygen that reaches the fish.

technology users NAECOER report healthy fish without stress that are actively feeding. This generates significant increases in weight at harvest.

As you have seen, nanobubbles can create a lot of value for your business
