Valorization of the chemical diversity of the tropical red seaweeds Acanthophora and Kappaphycus and their applications in aquaculture: A review

The role that seaweeds play as primary producers and ecosystems engineers in marine coastal is widely acknowledged. Seaweeds, however, are also important drivers the development of blue bioeconomy due to their vast diversity unique chemicals with a broad range industrial biotechnological applications. In tropical regions, seaweed production has been focused on few species only, because hydrocolloids used food industry. There strong need identify new applications red other sectors such aquaculture. Therefore, diversify culture seaweeds, more be investigated for chemical composition potential application aquaculture, then, develop method sustainable cultivation candidates enhance economic potential. Based this context, we analyze value edible Acanthophora spp., an under-valued which naturally abundant countries, Kappaphycus commercially valuable commonly polysaccharide extraction. (polysaccharides, phytohormones, amino acids, pigments) led research wide including pathogen control, immunostimulant, antioxidant, bioremediation, feed, UV protectants, increase seafood shelf life, animal colorant, growth regulator microalga culture. This review hopes stimulate interest among researchers investigate local seek greater added biomass compounds aquaculture sector. Additionally, information will help stakeholders benefit from these two by contributing diversification countries.
