Typical Compressed Air Applications in Aquaculture
Pneumatic Feeding
Pneumatic feeding systems require low-pressure air to transport feed from silos into net pens while preserving its quality. A reliable supply of high-quality air is essential for efficient and even feed distribution, contributing to optimal feed utilisation.
Used in sea-based aquaculture to mitigate environmental threats like algae blooms, bubble curtains require a dependable supply of compressed air to operate effectively. For optimum performance, the compressed air system should be designed to meet the net pen farms specific conditions.
Sea Pen Aeration (SPA) utilises compressed air to improve oxygen levels and mitigate harmful organisms from entering net pens. To create and maintain optimum conditions critical for fish health, SPA requires a reliable and energy-efficient supply of high-quality compressed air.
Compressed air is instrumental to the operation of airlift collection systems used to remove morts, faeces and sludge from net pens. It facilitates the process of drawing these up from the deepest part of a net pen to the top for removal.
Sea Pen Oxygenation (SPO) is used to counter the impact that seasonal or environmental conditions have on the oxygen levels in net pens. By directly injecting oxygen into the net pens, SPO ensures sufficient oxygen levels are maintained for fish health.
Recirculating Aquaculture System (RAS)
Recirculating Aquaculture Systems (RAS) use compressed air in various applications. Low pressure-air is particularly important to biofilter aeration and degassing, which both require aeration 24/7, 365 days a year.
On-Site Oxygen Production in Aquaculture
The injection of oxygen into Recirculating Aquaculture Systems (RAS) is necessary to sustain the biomass in the water volume needed to farm economically on land. When the operation chooses to produce the oxygen on-site, a dependable supply of compressed air will be required.
Fish Processing
Fish processing systems that sort, gut and convey fish are typically operated by compressed air. A reliable compressed air system is essential for quick and efficient fish processing. Compressed air also plays a key role in the production of Styrofoam boxes used for packaging and transporting fish.
