Algae Farming: Alternative in Aquaculture Sector

Algae farming has emerged as a promising alternative within the aquaculture sector, offering multifaceted benefits ranging from sustainable feed production to environmental remediation. This practice involves the cultivation of various species of algae in controlled settings, providing a renewable source of biomass rich in proteins, lipids, and carbohydrates. Algal cultivation presents opportunities for reducing dependence on traditional fish feed sources, mitigating environmental pollution through nutrient absorption, and serving as a viable solution for carbon sequestration. Moreover, algae farming showcases potential applications in pharmaceuticals, biofuels, and wastewater treatment, emphasizing its significance in fostering a more sustainable future for the aquaculture industry. This review discusses seaweed farming practices, different species of seaweed under cultivation practices, and their economic importance, especially in the Indian aquaculture system. In addition, this review focuses on commercial uses of seaweed and its byproducts. Finally, challenges and opportunities in seaweed farming are also discussed.
