Abstract: (243 Views)
Microagae are ancient and most adaptable microorganisms that by performing photosynthesis have a great role in producing oxygen and making life in the earth. These microorganisms have simple nutritional needs and could be cultured easily. Their biomass have various applications in different industries. They also have great potential to produce bioactive compounds such as polysaccharides, polyunsaturated fatty acids (PUFAs), antioxidants, and antimicrobial peptides, and play a significant role in enhancing aquatic animal health and promoting sustainable aquaculture. The use of microalgae species like Chlorella, Spirulina, and Nannochloropsis in the diet of fish and shrimp has been shown to boost immune responses, increase resistance to bacterial pathogens such as Vibrio spp., and reduce parasitic loads including Ichthyophthirius multifiliis. In addition to their nutritional and environmental benefits, recent studies highlight the potential of microalgae as oral vaccine carriers in aquaculture. By expressing specific antigens within algal cells and administering them via feed, microalgae-based vaccines can stimulate protective immune responses in aquatic species without the need for injection. Furthermore, the inclusion of microalgae in aquaculture systems improves water quality and helps suppress the proliferation of pathogenic microbes. Overall, microalgae offer a promising, eco-friendly alternative to antibiotics by enhancing disease resistance and supporting sustainable production in modern aquaculture practices.
