Viral disease outbreaks are the major concern in aquaculture sector, affecting the development of crustacean aquaculture. Since the emergence of white spot syndrome virus (WSSV) in shrimp farms, this caused huge economic loss and societal impact in aquaculture industry. Several strategies include controlled environmental conditions; vaccines and immunostimulants were proposed for disease management. However, there are no effective treatment methods available for viral infections in shrimp; the search for alternative approach is the need of the hour. Recently, natural products from medicinal plants, marine algae, and their derivatives gained importance in the control of disease conditions in shrimps. In this review, we focused on the importance and role of seaweed polysaccharides on the effective management of WSSV in aquaculture animals. In addition, the review emphasizes the mechanisms of anti-WSSV activity of seaweed polysaccharides and their potential therapeutic strategies.

病毒性疾病暴发是水产养殖部门的主要关切，影响甲壳类水产养殖的发展。自从虾场出现白斑综合症病毒（WSSV）以来，这对水产养殖业造成了巨大的经济损失和社会影响。几种策略包括控制环境条件。提出了用于疾病管理的疫苗和免疫刺激剂。但是，没有有效的治疗方法可用于虾的病毒感染。寻找替代方法是需要时间的。近来，来自药用植物，海藻及其衍生物的天然产物在控制虾的疾病中变得越来越重要。在这篇综述中，我们集中于海藻多糖对水产养殖动物中WSSV有效管理的重要性和作用。
