Worldwide, aquaculture organisms are often infected by viruses, bacteria, fungi, and parasites. These organisms are responsible for the high mortality, leading to major financial loss in this industry. Controlling microbial diseases in aquaculture is not that easy; it is much more difficult than prevention because it is a complex environment. Farmers are using different strategies to overcome this issue; however, recognizing new dietary supplements for preventing the disease is always helpful to aquaculture farmers. More recently, the bioreduction of nanoparticles using seaweed extract and its sulfated polysaccharides are fascinated because of the presence of various bioactive properties. Also, it is well-accepted that the green chemistry approach is a superior alternative to the synthesis of non-toxic nanoparticles. This chapter covers the major microbial disease in aquaculture and its management, the application of nanoparticles in aquaculture, the importance of seaweed and its sulfated polysaccharide-mediated silver nanoparticles and its role in Vibriosis and WSSV disease control in aquaculture. This chapter provides a superior understanding to the researchers for formulating novel health supplements using seaweed and its sulfated polysaccharides mediated nanoparticles to overcome bacterial and viral disease in aquaculture.

Keywords: Seaweed, Silver nanoparticles, Sulfated Polysaccharide, Vibriosis, WSSV.
