Developing ecological approaches for disease control is critical for future sustainable aquaculture development. White spot syndrome (WSS), caused by white spot syndrome virus (WSSV), is the most severe disease in cultured shrimp production. Culturing specific pathogen-free (SPF) broodstock is an effective and widely used strategy for controlling WSS. However, most small-scale farmers, who predominate shrimp aquaculture in developing countries, cannot cultivate SPF shrimp, as they do not have the required infrastructure and skills. Thus, these producers are more vulnerable to WSS outbreaks than industrial farms. Here we developed a shrimp polyculture system that prevents WSS outbreaks by introducing specific fish species. The system is easy to implement and requires no special biosecurity measures. The promotion of this system in China demonstrated that it allowed small-scale farmers to improve their livelihood through shrimp cultivation by controlling WSS outbreaks and increasing the production of ponds.
发展生态疾病控制方法对于未来可持续水产养殖的发展至关重要。白斑综合征（WSS）是由白斑综合征病毒（WSSV）引起的，是养殖虾类生产中最严重的疾病。养殖特定无病原体（SPF）亲虾是控制 WSS 的一种有效且广泛使用的策略。然而，在发展中国家占主导地位的大多数小规模养殖户由于缺乏必要的基础设施和技能，无法养殖 SPF 虾。因此，与工业化养殖场相比，这些生产者更容易受到 WSS 爆发的影响。在这里，我们开发了一种虾类混养系统，通过引入特定的鱼类物种来预防 WSS 爆发。该系统易于实施，不需要特殊的生物安全措施。在中国推广该系统表明，通过控制 WSS 爆发和增加池塘产量，它允许小规模养殖户通过虾类养殖来改善生计。
