Global RAS-based Aquaculture Competitive Landscape Professional Research Report 2025
RAS-based aquaculture, or Recirculating Aquaculture Systems, refers to a method of fish farming that utilizes closed-loop systems to continuously recirculate and filter water within a controlled environment, minimizing water consumption and waste discharge. In RAS systems, water is continuously pumped through tanks or ponds containing fish, where it undergoes mechanical and biological filtration to remove waste products and maintain water quality. This filtered water is then recirculated back into the system, reducing the need for large volumes of freshwater and minimizing environmental impacts associated with traditional open-water aquaculture practices. RAS-based aquaculture enables intensive fish farming in land-based facilities, allowing for year-round production of high-quality seafood regardless of geographical location or climate conditions. Additionally, RAS systems offer opportunities for biosecurity and disease control, as well as potential integration with other aquaculture technologies such as aquaponics, where fish waste is used to fertilize plants grown hydroponically. As global demand for seafood continues to rise, RAS-based aquaculture presents a sustainable and efficient solution to meet this demand while minimizing environmental impacts and ensuring food security.
