Sewage-fed aquaculture repurposes treated wastewater to create a nutrient-rich environment for fish farming. This process is a sustainable approach to waste management, especially in areas with limited resources. Through the natural filtration properties of aquatic plants and the nutrient absorption by fish, sewage-fed aquaculture can help mitigate water pollution while producing fish for consumption. In countries like India and Bangladesh, this method is used to support rural economies by reducing production costs and promoting self-sufficiency. However, strict regulations and thorough water quality monitoring are essential to ensure that the fish produced are safe and healthy for consumption.
