Aquaculture is growing fast across Africa, but every farm depends on one invisible ingredient: oxygen. From tilapia in Zambia to salmon in Norway, dissolved oxygen determines growth, survival, and profitability. Traditionally, many farms have relied on oxygen cylinders, but unpredictable deliveries and high costs limit progress. Pressure Swing Adsorption (PSA) technology is changing that story by providing reliable, on-site oxygen generation. Discover how farms from Botswana to Vietnam are using PSA systems to cut costs, improve fish health, and build a more sustainable future for aquaculture.
