MahuWévi, the solution for aquaculture that sustainably feeds The MahuWévi is an advanced oxygenation system designed for sustainable fish farming in sub-Saharan Africa, particularly for tilapia. It provides efficient, low-cost oxygen enrichment, ensuring high dissolved oxygen levels through short, regular micro-injections, while operating with minimal energy use. This technology reduces water demand by 50%, lowers nitrogen and phosphorus runoff, and enhances water recycling for crop irrigation, supporting a circular economy. Adaptable to various users, MahuWévi boosts profitability (with an ROI of 30%) and aligns with key SDGs by promoting food security, environmental sustainability, and economic opportunities for youth and women in aquaculture.
