Abstract
Seaweeds or marine macroalgae, gaining importance for their nutritional and economic potential, yet their incorporation into diets is limited. Seaweeds are categorised into red (Rhodophyta), green (Chlorophyta) and brown (Phaeophyta) are rich in vitamins, minerals, proteins, essential amino acids and polysaccharides. Their potential health benefits are underutilised due to limited awareness. Historically used for food and medicine, they are now gaining importance in aquaculture as a feed supplement. Global seaweed production has tripled since 2000, contributing significantly to food security and rural economies. It offers nutritional and economic benefits, with wide applications such as cosmetics, agrochemicals, biofuels and pharmaceuticals. Their usage in aquafeeds is promising, but effectiveness varies by seaweed species and inclusion levels. Recent studies reveal that certain seaweeds improve fish growth and feed efficiency, while others may have adverse effects. Further research is needed to optimipe seaweed inclusion in aquafeeds and to explore their full potential for sustainable aquaculture.
