Sewage-fed aquaculture, a prevalent practice across various regions in Asia, involves fertilizing fish production with wastewater-a method known for its efficiency in utilizing resources. One prominent approach within this practice is the sanitary engineering pond system, which not only aids in fish cultivation but also significantly conserves energy. Today, sewage-fed aquaculture has become a well-established industry, offering economic stability due to its ability to yield marketable products with proper maintenance efforts. This unique culture system utilizes nutrient-rich water sources from urban and industrial areas for both aquaculture and agriculture, promoting sustainable production. By recycling used water from urban and industrial sources, sewage-fed aquaculture mitigates environmental pollution, fosters a sustainable ecosystem, and contributes to biodiversity conservation.
