An integrated aquaculture system utilizing duckweed serves dual purposes: it acts as a sustainable feed source for fish while simultaneously bioremediating wastewater produced by aquaculture operations. This approach enhances resource efficiency.

Integrating duckweed into aquaculture systems presents a multifaceted approach to feeding aquatic species and managing waste. Duckweed, a fast-growing aquatic plant, is known for its high protein content and ability to absorb excess nutrients from water, making it an ideal candidate for this dual-purpose role. Duckweed can thrive on these nutrients, particularly nitrogen and phosphorus, often present in high concentrations due to fish excretion. By cultivating duckweed in conjunction with fish farming, the system not only provides a nutritious feed alternative but also mitigates the environmental impact of aquaculture by reducing nutrient pollution. Moreover, the harvested duckweed can be processed into feed pellets or used directly as feed for various fish species. This not only reduces reliance on traditional feed sources but also promotes sustainability within the aquaculture industry by closing the nutrient loop—waste from fish becomes food for plants that can then be fed back to the fish. This innovative approach aligns with current trends towards sustainable aquaculture practices that aim to minimize environmental footprints while maximizing productivity and resource efficiency.
