Recirculating Aquaculture Systems (RAS): A Sustainable and Technology-Driven Future for Aquaculture

What would happen when fish could be grown with 5-10% of the amount of water needed in the traditional ponds? It is not a futuristic idea but the basic promise of smarter and more sustainable feeding our planet (Ahmed and Turchini, 2021). Global aquaculture production is the fastest-growing food production sector in the world, with its output growth more than 600 per cent since 1990. As the world population is predicted to be 9.7 billion by 2050, the demand of seafood protein is set to almost increase twofold (Brown et al., 2025). Since capture fisheries are almost stagnant, aquaculture is the only solution to the growing disparity between seafood demand and supply rates (Ahmed & Turchini, 2021).
