Azolla, a fast-growing aquatic fern, is gaining recognition as a sustainable and cost-effective feed supplement in aquaculture. Rich in protein, essential amino acids, vitamins, and minerals, Azolla enhances fish growth, feed efficiency, and water quality through nutrient absorption. Its integration into aquafeeds, particularly at optimal inclusion levels, can reduce reliance on traditional protein sources and lower feed costs. However, challenges such as anti-nutritional factors and nutrient variability require further research and innovation in processing and cultivation. Overall, Azolla presents significant potential for advancing sustainable aquaculture practices and supporting environmental and economic benefits.
