Oxzo has received a $25 million strategic investment from S2G Investments, marking one of the company’s most significant milestones as it accelerates its expansion across the global aquaculture sector. The investment, which adds to existing support from Fiordo Austral and Altis, positions Oxzo to broaden its presence beyond its core markets of Chile, Norway, and Canada and bring its patented oxygenation technologies to additional international regions.
Headquartered in southern Chile, Oxzo has emerged as a critical technology provider to the aquaculture industry through its advanced oxygenation, aeration, and ozone-generation systems. These solutions enhance fish farming productivity, reduce mortality, support environmental sustainability, and improve animal welfare for both ocean-based and land-based operations. Oxzo’s technologies include automated oxygenation pontoons and mobile oxygen generation units that help optimize conditions throughout the fish production cycle, improving operational efficiency and biological outcomes.
Independent industry data shows that salmon farmers in Chile using Oxzo’s technologies have achieved biomass increases of 5% to 10%, cost reductions of up to 5%, and more than 24% reductions in fish mortality. In Norway, the company is working with three major salmon producers, helping address the country’s leading aquaculture health challenge by reducing fish stress and mortality while supporting efforts to mitigate sea lice. In Canada, Oxzo’s systems are assisting producers as they adapt to evolving regulatory frameworks, providing alternatives to more capital-intensive approaches such as land-based grow-out facilities or closed containment systems.
S2G Investments, which manages approximately US$2.5 billion in committed capital and has invested in more than 100 companies across five continents, has made Oxzo only its second Latin American portfolio investment under its Oceans strategy.
Launched in 2020, the strategy focuses on solutions that strengthen the ocean value chain, improve transparency, support ecosystem regeneration, and reduce barriers to adopting sustainable marine practices.
With this funding, Oxzo plans to extend the reach of Chilean-developed aquaculture innovation into new international markets, reinforcing its aim of advancing more productive, sustainable, and responsible fish farming practices worldwide. The investment further supports the company’s ambition to remain an essential partner for producers seeking efficient and environmentally aligned oxygenation technology.
